quantitative research title about food industry

Set-up and number of reactions needed for simultaneous quantification of four samples with qPCR and ddPCR. For qPCR, measurements were made in duplicate. A quantitative survey provides data on the amounts of various foods consumed by individuals and or populations; qualitative research provides information on the kind of foods consumed, food preparation procedures, food preferences, cultural influences and attitudes towards foods. Several advantages are proposed for the use of dPCR instead of qPCR in routine GMO testing: 1) it enables absolute target copy number to be detected and avoids the amplification efficiency bias observed with qPCR [11], [19], 2) it overcomes dependence on the availability of references or standards [18], 3) it provides data with the high precision and confidence necessary for metrological use [11], [19], 4) it provides more accurate data at low target copy numbers than qPCR [20], allowing quantification of low GMO content, and 5), because of its tolerance to inhibitors as an end-point measurement, it can reduce the biases linked to matrix type often observed with qPCR [18]. Based on this criterion, aLOQ was estimated to be around 5 copies for the hmg system, and 18 copies for the MON810 system and for the duplex ddPCR assay (Table S5). Readers will gain increased knowledge about qualitative research and greater competency in evaluating this type of research. Are beans enough to substitute meat proteins?

Browsing through these titles will give you an idea about how you can write yours. The impact of the size of the plate on our level of hunger. One approach, termed chamber digital PCR (cdPCR), relies on the partitioning of up to a few thousand individual reactions in microfluidic chambers. It might save your time researching about possible topics for your research. The most harmful preservatives in fast food. Just pick a quantitative research title about cookery from the list below! Can’t you read my question??? Vegetarianism: a new trend or philosophy? You need to understand the food industry’s categories, their size, segmentation and forecasts. Before introducing a new technology in a laboratory, one has to verify its practicability for daily use [24]. Qualitative research isn’t about numbers – it’s about thoughts and opinions. Is the atmosphere that important for restaurants? The second approach, called droplet digital PCR (ddPCR), combines partitioning of the PCR test into several thousands or millions of individual droplets in a water-oil emulsion, with the use of flow cytometry to count positive PCR tests. Discover a faster, simpler path to publishing in a high-quality journal. 2 - The American supermarket: Stuck in a timewarp? We talk about it all the time: planning what to eat next, recalling the delicious dishes we had before, and even watching culinary shows. It was recently suggested that it is preferable to expose gDNA to endonuclease restriction in order to improve amplification efficiency and to increase the accuracy of GMO target copy number measurement with cdPCR [19]. In the absence of a DNA reference material certified for absolute copy number concentration, trueness could only be assessed for the MON810 content. This finding supports the fact that the duplex MON810/hmg ddPCR assay can be used over a wide range of target concentrations to determine the MON810 content in a given sample, and that values around 115,000 copies constitute the upper range of quantification with ddPCR. qPCR efficiency and hence quantification by qPCR of endogene and transgene, can be influenced by many factors, including inhibitors, present in food and feed samples, leading to significant under- or over-estimation of GMO content [8], [11]. False-positive rates observed with ddPCR. Duplex ddPCR reaction mixes were prepared as follows. However, most of the proposed solutions are not practical and reliable quantification of GMOs in food and feed samples still remains a major challenge. Yes The ddPCR duplex assay response was investigated over target concentrations ranging from approximately 0.02 to 118,000 hmg copies and from approximately 0.0008 to 4300 MON810 copies per 20 µL of ddPCR reaction. Affiliation Linearity over the dynamic range was determined by the coefficient of correlation R2, calculated on the average of the target copy numbers measured in the replicated dilution series for both qPCR and ddPCR. Garlic and onions: Ayurveda point of view. For comparison, qPCR would take 160 minutes to generate results (see Table S10 in Appendix S2). https://doi.org/10.1371/journal.pone.0062583.t002. It has already been asserted that qPCR offers a much broader dynamic range than digital PCR [16]. 6 - Go veggie: Boost your health and save the planet? Research Proposal submitted to the University of Dublin Trinity College, in partial fulfilment of the requirements for the Bachelor in Nursing Studies However, the ddPCR performance demonstrated in this study on real routine samples should lead to greater confidence and easier adoption of digital PCR technology, to generating more precise data on everyday tests, and at overall better cost per sample. Both qualitative and quantitative research falls under consumer research and is normally completed by market research companies that specialize in this type of research. The absolute limit of detection (aLOD) is the lowest target copy number in a sample that can be reliably detected, but not necessarily quantified [25]. Put simply, quantitative research involves gathering extensive data from the relevant sample size of the market sector or sub-sector that we’re focusing on. https://doi.org/10.1371/journal.pone.0062583.s008, https://doi.org/10.1371/journal.pone.0062583.s009. 640118/2008/67 on performing activities as holder of the national standard MIRS/NIB/FITO for the amount of substance in food of plant origin. The aim of this study was therefore to evaluate the application of ddPCR for quantitative analysis in food and feed samples. It is noteworthy that the deviation between the MON810 content measured by ddPCR and the reference value tended to increase with lower target copy number. However, two subcategories make great research titles about the cookery strand: fast food and restaurants. Food adulteration and law. Time needed for quantification with qPCR and ddPCR. In the case of GMO quantification, the target of the event-specific assay and the target chosen for endogene quantification are present as unique copies in the host plant genome and are not linked. The overall repeatability could also be estimated by analyzing the results of the experiment performed for aLOQ and dynamic range determination. Standard curves were prepared from five serial dilutions of the copy/copy ratio certified reference material ERM-BF413gk (starting from approximately 100 ng to 1 ng DNA per reaction) and used in two replicates. The impact of a visual representation of a dish on a customer’s review. In order to avoid biases as much as possible when comparing qPCR and ddPCR quantification, we transferred the inter-laboratory validated qPCR hmg- and MON810-specific assays to ddPCR technology with the minimum of adaptation. In this study, the applicability of droplet digital PCR (ddPCR) for routine analysis in food and feed samples was demonstrated with the quantification of genetically modified organisms (GMOs). Moreover, the key assay parameters (primer and probe concentration, thermal profiles) were not modified. It has to be noted that there is substantial empirical knowledge about the efficacy of DNA extraction methods related to sample matrix. What are the healthiest sugar substitutes? In this study, the applicability of droplet digital PCR (ddPCR) for routine analysis in food and feed samples was demonstrated with the quantification of genetically modified organisms (GMOs). Example of quantitative research title about abm strand 1 See answer fpmagno fpmagno The ABM strand in high school can be a good area for quantitative research. Self-service kiosk in fast-food restaurants. Set-up and number of reactions needed for simultaneous quantification of 23 samples with qPCR and ddPCR. Error bars represent the standard deviation between the five replicates at each target concentration. From these results, it was concluded that the duplex ddPCR assay performs as well as the singleplex ddPCR assays without any additional optimization. They are accommodating for students who want to write a paper related to food. The fifth series was prepared by one operator on a second day and ddPCR reactions were performed on another 96-well plate. An attempt to optimize the duplex qPCR assay was made by varying primers and probe concentration of both systems. Linearity of response, absolute limits of detection and quantification, repeatability over the dynamic range of the ddPCR endogene and transgene assays were assessed. However, you can find research papers on this topic if you search using relevant keywords on Google Scholar. The absolute limit of quantification (aLOQ) and absolute limit of detection (aLOD) for qPCR and ddPCR were determined on these experimental results. Comparison of quantification using singleplex and duplex ddPCR assays. The results obtained should be applicable to other fields where quantitative testing in food and feed samples is required. Transparent windows – transparency for the customers. How to Conduct Market Research for Restaurants. You’d want to work out what you’re going to write about first, to be honest. No, Is the Subject Area "Plant genomics" applicable to this article? And, of course, the top 10 food research questions for your paper! Samples representative of four different maize-containing matrices from routine GMO testing were used to test the applicability: seed-powder flour, corn flakes, wheat seed-powder flour with maize contamination, and feed containing maize (see Appendix S1 and Table S1). Trueness is defined as the closeness of agreement between the average value obtained from a series of test results and an accepted reference value [25]. The aLOQ of the qPCR MON810 specific method used in this study was initially estimated at 10 copies of the target MON810 sequence [22], and at a higher range of 31–63 copies in another recent study [18]. Because GMO content is calculated based on the ratio of transgene/endogene quantities, it would be more practical to perform endogene–transgene duplex reactions to reduce costs. PLOS ONE promises fair, rigorous peer review, Lower right quadrant: FAM (hmg) negative-VIC (MON810) positive droplet cluster. Technology trends in the restaurant industry. In each cartridge, one well was filled with a non template control (NTC) ddPCR mix, while the seven other wells contained ddPCR mixes with DNA extracted from the ERM-BF413ek CRM (average of 46,571 hmg copies and 324 MON810 copies). Genetically modified food: debunking myths. DNA quantification in the initial MON810 maize DNA solution was estimated by qPCR as described [23]. Therefore, a research title about a restaurant would be a perfect choice for someone who wants a career in this area. Table S10. e62583. What are the advantages of the macrobiotic diet? MON810 content was determined by qPCR, using relative quantification according to the standard curve approach. To many food and nutrition professionals the term research elicits thoughts of data, numbers, measurement, controls, controlled environments, reliability, randomized clinical trials, interventions, and outcomes. How to achieve the umami flavor in your cooking? Food and cookery is a wide area, which means it includes all the issues related to food. Results from the dilution series used for the dynamic range, the aLOD and aLOQ determination, and the overall repeatability. Why is a plant-based diet getting more and more popular? In this study, similar variability of the measured target copy numbers (Table S5 and Figure 1) and of the MON810 content was observed at lower target concentrations (Table S5 and Figure 3). broad scope, and wide readership – a perfect fit for your research every time. Recently, a cdPCR commercial system has been demonstrated that enables suitable metrological performance for the certification of the copy number ratio of reference materials used in GMO testing [11], [19]. How are robots used in the restaurant industry? We use cookies to give you the best experience possible. Currently, two approaches are used in commercially available dPCR systems [15], [16]. Tired of searching a sample? Fast food vs. slow food: what will be the trend in the future? https://doi.org/10.1371/journal.pone.0062583.g003. The absolute limit of quantification (aLOQ) is the lowest target copy number in a sample that can be reliably quantified with an acceptable level of precision and accuracy [25]. The impact of the quick-service restaurants on the speed of life. However, the hmg and MON810 were affected differently under all the tested conditions, resulting in under-estimations of the MON810 content and/or loss of sensitivity (data not shown). I know, I know, “I’m writing about food. The absolute number of target nucleic acid molecules contained in the original sample before partitioning can be calculated directly from the ratio of positive to total partitions, using binomial Poisson statistics [15]. Top 100 Research Topics & Titles about Food & TVL When you look for a good research paper topic, you can easily become the severest critic of any proposed idea. https://doi.org/10.1371/journal.pone.0062583, Editor: Joshua L. Heazlewood, Lawrence Berkeley National Laboratory, United States of America, Received: January 29, 2013; Accepted: March 22, 2013; Published: May 2, 2013. The average number of droplets read for each ddPCR reaction included in the data analysis was 13,606 with a standard deviation of 931 droplets (coefficient of variation cv = 6.8%). This asymmetry in concentration renders establishment of a qPCR duplex assay targeting both the MON810 transgene and the hmg endogene even more difficult. That is why the research design should reflect the nature of your research… Inhibition effect on MON810 quantification in qPCR and ddPCR. Due to pipetting errors, that were noted after loading the 8-well cartridges with ddPCR mixes, data from one reaction (1.4% of the total dataset) were excluded from the analysis. It includes all the businesses that produce most of the food supplies. The amount of fats children and adults need: statistical analysis. Chemicals of Potential Concern Here are a few other tips you can use to make sure your title will be part of the recipe for an effective research paper: Make sure your research title describes (a) the topic, (b) the method, (c) the sample, and (d) the results of your study. All samples were stored at −20°C. Cookies Policy. Coffee for breakfast: a destructive habit for women’s health. we will assume that you agree to our Finally, ddPCR throughput and cost are advantageous relative to those of qPCR for routine GMO quantification. The use of buttermilk in baking in India. Intra- and inter-cartridge (ddPCR 8 well chips) repeatability was determined on five independent series consisting of seven replicates of the ERM-BF413ek (approximately 100 ng and an average of 46571 hmg copies and 324 copies of MON810 per 20 µl reaction) and one NTC. Feel free to alter any topic to your liking. Repeatability over the dynamic range was determined by the coefficient of variation (cv) of the measured target copy number or of the MON810 content between the replicates of the dilution series. The use of cdPCR, taking into account prices per chip or plate (from US$150 to US$400 each) [16] and using the proposed set-up for ddPCR (four runs, i.e. An additional set of experiments was performed to establish repeatability between different emulsification runs. That’s why they come to Mintel. What makes the process of fast food cooking so fast? However, its use for target quantification can be seriously limited by a significant bias when the target is present at low concentrations in a background of high numbers of non-target nucleic acids in the sample [4]–[7]. Based on the experience acquired during this study and assuming the samples and mixes are already prepared, the simultaneous analysis of these four samples with ddPCR would require approximately 190 minutes. Therefore, apart from the mastermix and settings that are specific to the QX100 droplet system, primers and probe nucleotide sequences and concentrations, DNA concentration, and PCR thermo-profile were kept identical to those in the qPCR assays. With ddPCR, the standard curve is not needed and a duplex MON810/hmg assay with a wide dynamic range is used. The primers and probes of both the hmg and MON810 systems were mixed in the qPCR or ddPCR volumes to final concentrations equal to those in the original singleplex assays. The demonstrated application of ddPCR for routine quantification of GMO content in food and feed samples should act as an inducement to introduce this technology in other areas where precise analytical testing is required in food and feed samples. Considering the cost of reagents, consumables and labor at NIB and the above proposed set-ups for GMO testing, the quantification of a given transgene in four samples with ddPCR would cost approximately US$20.9 per sample and US$22.3 using qPCR. Why are cereals becoming the breakfast of the past? If you are not sure how to choose a food research topic, here is a short guide for you. Several MON-ØØ81Ø-6 (MON810) maize seed powder based, certified reference materials (CRM) were purchased from the EU Joint Research Centre, IRMM (Institute for Reference Materials and Measurements, Geel, Belgium). Evaluation of qPCR duplex systems has shown that the hmg system performed identically in duplex and singleplex qPCR reactions, while MON810 amplification was significantly affected in the duplex reactions, showing signal values approximately 5.5 Cq higher than in singleplex reactions (data not shown). Set-up and number of reactions needed for quantification with qPCR and ddPCR (full 96 well-plate). Trueness was also evaluated on two additional CRMs and on samples from the ILC-EURL-GMFF proficiency program: ddPCR results showed better agreement with the target values than qPCR and were in accordance with the trueness acceptance criterion (Table 1). Salmonella cases in port cities: a quantitative evaluation. No, Is the Subject Area "Nucleic acids" applicable to this article? https://doi.org/10.1371/journal.pone.0062583.s007. How do different types of wood for smoking affect the taste of meat? It is also very precise at very low levels of target content. A good research topic will not only earn you grades but would be beneficial in your daily dietary intake and appreciation of nutrition in life. You don’t have to be an experienced writer to come up with good topics for a food research paper. 178 Best Research Titles about Cookery & Food, We will write a custom essay specifically for you. Qualitative Methods in Food Related Research Lauren Blake Royal Veterinary College / LCIRAH ANH Academy Week June 2016. In all cases, a false-positive rate far below 5%, which is the generally used acceptance criterion, was observed (Table S7). A limited specificity study was however conducted on two samples containing either wild-type maize, or DNA from milk sample without maize. Error bars represent the standard deviation between the replicates for each series or in the aggregate. How do restaurant services manage the Big 8 allergens? The Jamaican influence on British cuisine. The average value of the pooled ddPCR duplex assay data at each dilution level of the dynamic range showed good agreement with the reference value of 3.85% cp/cp (ERM-BF413gk) (Table 1). The aim of your quantitative research is to determine the number of students in your High school taking up TVL Home Economics now, are planning to study food and beverage courses at college and will pursue a career in the food and beverage industry.

Four series were prepared by two operators and droplet amplification reactions were performed simultaneously on the same 96-well plate. The historical analysis: how have Asian hot pots become popular in the US? Yes Another important limitation is its sensitivity to the frequent presence of inhibitors co-extracted with nucleic acid from complex matrices [8]. Inter- and intra-cartridge repeatability. It describes existing and innovative quantitative methods that could be applied to the vegetable industry for food safety and quality, and suggests ways in which such methods can be applied for risk assessment. Then, we moved on to the most relevant topics in our fast-paced world: fast-food and restaurants. Lower frame: TaqI digested DNA. Results of quantification performed with CRM certified for transgene/endogene copy ratio were expressed as percentages of the copy/copy ratio. Funding: The work was supported by the Slovenian Research Agency (grant Nos. A correlation between the climate and diet. The establishment of duplex reactions is straightforward and does not need optimization, which is also encouraging. The impact of freezing the dough on its quality. Wrote the paper: DM MM KG JZ. Using ddPCR duplex assay, we have measured the absolute numbers of MON810 transgene and hmg maize reference gene copies in DNA samples. The applicability of ddPCR was investigated for the quantification of GMO in food, feed and seed samples. The data is usually gathered using more structured research instruments Quantification of routine samples using ddPCR is therefore practical and has the potential to provide better throughput and cost-effectiveness than qPCR for GMO laboratories. A quantitative approach is all about collecting and analyzing numerical data. However, the application of cdPCR is limited by two important factors: the small dynamic range it offers (2–3 logs) and its relatively high price. : P4 0165). Therefore, any of the topics mentioned above would fit perfectly for the task of picking research topics on the food industry. Acceptance criterion for trueness is that the measured value has to be within ±25% of the accepted reference value over the whole dynamic range [24], [25]. Droplets were generated for each individual cartridge, and those droplets containing the PCR mixes of the three cartridges were transferred onto a single PCR plate for amplification followed by droplet count. The cookery and food industry is the largest one, among others. The Food Safety and Inspection Service (FSIS) has developed a list of the top food safety research areas of interest. All samples used for determining the dynamic range came from serial dilution of a single stock MON810 maize DNA sample. Other samples containing the MON810 maize event, and previously assayed by qPCR, were also used in this study. How do the proportions of the ingredients affect the texture of baked products? Competing interests: The authors have declared that no competing interests exist. The term food industry is an extremely broad one which tries to encompass an entire system that joins farms to end users through a channel of food manufacturers, wholesalers and retailers. The intention of this study was to demonstrate the usability of ddPCR in real-life routine diagnostics, rather than to re-investigate the recently reported metrological characteristics of this technology [15]. If you think that fast food is a recent invention, you are very much mistaken. Everything from agriculture and food processing to distribution and finances is included in the definition of the food industry. GMO laboratories use adapted DNA extraction methods that in some cases may reduce inhibition during the qPCR analysis. Yes This is because many students do not prepare well for the food research projects, owing to low analytical and quantitative research abilities to search for a relevant topic for research topics on food and cookery. People hate waiting for their food for too long, so the fast-food demand is growing. This sample questionnaire template consists of 20 questions for food quality evaluation, customer service, the value of food, hygiene levels, and overall customer satisfaction. Eating disorders and beauty standards: a quantitative evaluation. CiteScore values are based on citation counts in a range of four years (e.g. In our laboratory, the aLOQ estimated for the qPCR assay on the same DNA is 18 copies. Including NTC and quantification control reactions in the set-up, a total of 20 reactions would be necessary to reliably quantify MON810 in four samples. This wider range of concentrations can be attributed to the large number of partitions available for reactions in ddPCR (13,606 droplets on average in this work) compared to the number (765) available for cdPCR test. And it gives unlimited career opportunities for those interested in the art of cooking. Ask our academic expert for help with your assignment! For this reason, evaluation of duplex qPCR and ddPCR assays was performed and compared to the performance of singleplex assays. For example, looking into only a particular country or area would make your paper more specific. The ddPCR duplex assay was evaluated using three 8-well cartridges containing the singleplex hmg, the singleplex MON810 and the duplex ddPCR assay respectively. Applicability of the technology has been verified on representative matrices found in routine samples, and on the range of GMO content usually found in routine samples and relevant to different international labeling requests. Nevertheless, the MON810/hmg ddPCR duplex assay met trueness acceptance criteria throughout the whole dynamic range. One example of the need for quantitative nucleic acid analysis in food and feed is the testing for genetically modified organisms (GMOs). In addition, for all experiments performed in this study, NTC resulted in no signal (no positive droplet). Since inhibition is assessed during the screening and identification phases of GMO testing and given the demonstrated tolerance of the assay for amplification inhibition, it is not necessary to control the inhibition at the ddPCR quantification stage. Consequently, diluted DNA samples were used to determine the MON810 content with qPCR. More specifically, their ability to perform well with different sample matrices and within a range of concentrations relevant for GMO testing has to be demonstrated [24]. In many aspects of basic research, diagnostic tests, and commercial processes, the advent of modern analytical technologies has provided the ability to detect and quantify nucleic acid targets with unprecedented sensitivity and specificity. ddPCR workflow and data analysis were performed as described (see Appendix S1) [15]. The ddPCR response was linear over concentrations ranging from an average of 5 to 118,000 hmg copies (0.02% to 99.5% positive droplets) with a coefficient of correlation (R2) of 0.9990. This collection of research titles about culinary consists of every topic from food poisoning to preservation methods. Upper left quadrant: FAM (hmg) positive-VIC (MON810) negative droplet cluster. Interestingly, for the DNA extracts obtained with NSF, very low differences were observed between the MON810 content determined by ddPCR in the stock (presenting inhibition with qPCR) and the diluted DNA solutions for both matrices (Table S8 in Appendix S2). Acceptance criterion for precision is ±25% of the target content (from 2.89% to 4.81%) represented by the dashed lines. This book focuses on the food safety challenges in the vegetable industry from primary production to consumption. The food and restaurant market is a vast and demanding industry that is expanding at a rapid pace. 10 hot topics in food and beverage development 1 - The American diet: One long snack? Quantitative research is a method that studies numerical values. What will you prove? Similarly, the aLOQ of the duplex ddPCR assay was also in a range similar to the aLOQ measured in cdPCR (15–56 transgene copies), assessed only on the MON810 assay [18]. Tea ceremonies in Japan as an art: ethnographic research. The hmg gene was used as the endogenous control gene for maize. Title: Systems Approach and Qualitative Methods in Food Related Research … This page contains specific research studies associated with our food safety research priorities. Upper frame: Non digested DNA. Additionally, the repeatability of the duplex assay in measurements of the MON810 content appears slightly better that of the singleplex assays.
