Rapid and sensitive detection of shrimp allergens within 30 min using a new food nucleic acid release agent combined with a fast real-time PCR assay
To achieve fast on-site detection of shrimp allergens in food, this study established a new direct, fast, and real-time quantitative polymerase chain reaction (PCR) technology. The technology completed nucleic acid extraction in 4 min using a new nucleic acid releaser, and the DNA samples were detected using fast qPCR within 25 min (total detection was approximately 30 min). The results indicated that the direct fast qPCR can specifically detect shrimp, with a limit of detection of 0.0001% of shrimp in artificially simulated meat samples and a detection precision variation coefficient (CV value) was less than 5%. It successfully identified shrimp in different types of commercial food samples. As a simple, fast, and sensitive nucleic acid testing technology, it has broad application prospects for the on-site detection of shrimp allergens in food.
期刊介绍:
LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
