Recombinase polymerase amplification combined with Pyrococcus furiosus Argonaute for fast Salmonella spp. testing in food safety.

Foodborne illness caused by Salmonella spp. is one of the most prevalent public health problems globally, which have brought immeasurable economic burden and social impact to countries around the world. Neither current nucleic acid amplification detection method nor standard culture method (2-3 days) are suitable for field detection in areas with a heavy burden of Salmonella spp.

Design and development of a rapid meat detection system based on RPA-CRISPR/Cas12a-LFD.

In recent years, meat adulteration safety incidents have occurred frequently, triggering widespread attention and discussion. Although there are a variety of meat quality identification methods, conventional assays require high standards for personnel and experimental conditions and are not suitable for on-site testing. Therefore, there is an urgent need for a rapid, sensitive, high specificity and high sensitivity on-site meat detection method.

A novel FCTF evaluation and prediction model for food efficacy based on association rule mining.

Introduction: Food-components-target-function (FCTF) is an evaluation and prediction model based on association rule mining (ARM) and network interaction analysis, which is an innovative exploration of interdisciplinary integration in the food field.

Methods: Using the components as the basis, the targets and functions are comprehensively explored in various databases and platforms under the guidance of the ARM concept. The focused active components, key targets and preferred efficacy are then analyzed by different interaction calculations.

Comparative phylogenetic analysis of oolong tea ( tea) using complete chloroplast genome sequences.

tea, a variety of oolong tea, is produced in Chaozhou, Guangdong Province, China, and is characterized by numerous hybridizations and polyploidization. To assess the genetic diversity and phylogenetic relationships among tea and other oolong teas, an integrated circular chloroplast genome was constructed for thirty species of tea from Chaozhou. The genome of tea is a circular molecule of 157,041-157,137 bp, with a pair of inverted repeats (26,072-26,610 bp each) separated by a large single copy (86,615-86,658 bp) and small single copy (18,264-18,284 bp).

SPME-GC-MS combined with chemometrics to assess the impact of fermentation time on the components, flavor, and function of Laoxianghuang.

Laoxianghuang, fermented from L. var. of the family, is a medicinal food.

Effect of Amylose and Crystallinity Pattern on the Gelatinization Behavior of Cross-Linked Starches.

Starches from normal maize (NM), normal potato (NP), waxy maize (WM), and waxy potato (WP) were cross-linked with seven different concentrations (0.01, 0.05, 0.
