Phytosterols are important micronutrients in human diets. Evidence has shown that phytosterols play an essential role the reduction of cholesterol blood and therefore decrease cardiovascular morbidity. In this study, content composition different kinds vegetable oils were analyzed, total phytosterol intake contribution foods to estimated based on consumption data. The results showed contents rice bran oil, corn rapeseed oil higher than those other Chinese diet was about 392.3 mg/day. main...
The detection of adulteration high priced oils is a particular concern in food quality and safety. Therefore, it necessary to develop authenticity method for protecting the health customers. In this study, fatty acid profiles five edible were established by gas chromatography coupled with mass spectrometry (GC/MS) selected ion monitoring mode. Using spectral characteristics ions equivalent chain length (ECL), 28 acids identified employed classify kinds using unsupervised (principal component...
Chemical composition of secondary metabolites is great importance for quality control agricultural products. Black sesame seeds are significantly more expensive than white seeds, because it thought that black beneficial to human health seeds. However, the differences in nutrient between and still unknown. The current study examined levels different via use a novel metabolomics strategy. Using widely targeted data, we obtained structure content 557 metabolites, out which 217 were identified,...
In the experiment, a high-performance liquid chromatography and electrospray ionization-tandem mass spectrometry with selected reaction monitoring was used to simultaneously determine various classes of phytohormones, including indole-3-acetic acid, α-naphthaleneacetic 2-chlorobenzoic 4-chlorobenzoic indole-3-butyric gibberellic 2,4-dichlorophenoxyacetic 2-naphthoxyacetic abscisic 2,3,5-triiodobenzoic uniconazole, paclobutrazol 2,4-epibassinolide in rape tissues. The analyses were separated...
The effect of UV-B radiation exposure on transgenerational plasticity, the phenomenon whereby parental environment influences both parent's and offspring's phenotype, is poorly understood. To investigate impact exposing successive generations rice plants to seed morphology proanthocyanidin content, local traditional variety 'Baijiaolaojing' was planted terraces in Yuanyang county subjected enhanced treatments. intensity that caused maximum phenotypic plasticity (7.5 kJ·m-2) selected for...
Abstract The method of headspace coupled with comprehensive two‐dimensional GC–time‐of‐flight MS (HS‐GC × GC–TOF/MS) was applied to differentiate the volatile flavor compounds three types pure vegetable oils (sesame oils, peanut and soybean oils) two adulterated oils). Thirty common volatiles, 14 particular flavors were identified from sesame respectively. Thirty‐one potential markers (variables), which are crucial forming different oil flavors, selected volatiles in they analyzed using...
To prevent the potential adulteration of flaxseed oil with high amounts nutritional components, a simple and rapid detection method was proposed based on ion mobility spectrometry (IMS).
Aflatoxins, highly toxic and carcinogenic to humans, are synthesized via multiple intermediates by a complex pathway in several Aspergilli, including Aspergillus flavus. Few analytical methods available for monitoring the changes metabolite profiles of aflatoxin biosynthesis under different growth environmental conditions. In present study, we developed D-optimal mixture design solvent system, methanol/dichloromethane/ethyl acetate/formic acid (0.36/0.31/0.32/0.01), that was suitable...
Adulteration of edible oils has attracted attention from more researchers and consumers in recent years. Complex multispecies adulteration is a commonly used strategy to mask the traditional detection methods. Most were only concerned about single targeted adulterants, however, it was difficult identify complex or untargeted adulterants. To detect oil, identification characteristic markers adulterants proposed be an effective method, which could provide solution for detection. In this study,...
