Deficiency of folates can cause various health problems, and germination is a potential way to enrich folates in grain-based food materials. In the present study, the effects of six amino acids (phenylalanine, tyrosine, tryptophan, glutamate, γ-aminobutyric acid, and p-aminobenzoic acid) on folate accumulation during wheat germination under red lig...

BACKGROUND Ultraviolet B (UV‐B) radiation can enhance the accumulation of phenolic compounds (PCs) in barley seedling, although this may result in severe oxidative damage. In the present study, the role of spermidine in alleviating oxidative damage and regulating synthesis of PCs in barley seedlings under UV‐B stress was investigated. RESULTS Exog...

To further reveal the role of feruloylation of arabinoxylan (AX) in regulating the heat-evoked polymerization behavior of gluten, AX was extracted from wheat bran and in situ modified with lime to obtain AX with controlled ferulic acid (FA) content. The effects of AX with varied FA level on the heat-evoked polymerization of gluten were comparativel...

The utilization of rapeseed meal in food is limited due to its abundant glucosinolates (GLs). In this study, an LC-MS/MS method for GLs determination in rapeseed meal was developed. Then, the degradation of GLs using rapeseed sprouts derived myrosinase (MYR) was investigated. Results showed that 11 kinds of GLs were identified in rapeseed meal. The...

Chrysanthemum has a long history of being used to attenuate various oxidative stress-related discomforts and diseases; however, its mechanisms remain unclear. In this study, the antioxidant effect of chrysanthemum aqueous extract was investigated, and the potential mechanisms were explored via a metabolomics study. Chrysanthemum extract could signi...

This study investigated the content of deoxynivalenol (DON), sugars, proteins, phenolics, amino acids, the antioxidant capacity and antioxidant enzymes activities of Fusarium naturally contaminated wheat (FCW) during soaking and germination. Results showed that the concentration of DON in FCW was less than 100 μg/kg after soaking and 4 days of germ...

This study aimed to develop a fermentation process that allows the concomitant production of dextran (a texture-enhancing agent) and vitamin B12 (in situ fortification) for bread applications. Mixed fermentation of soya flour or rice bran using Propionibacterium freudenreichii DSM 20271 and Weissella confusa A16 with added sucrose resulted in subst...

Red, white, blue, green, and yellow lights were applied to investigate their effects on folate accumulation in wheat seedlings. The different lights, especially red light, significantly increased the total folate content. Total folate showed maximum accumulation under 30 μmol/(m2·s) of red light, with an increase of 24% compared with the control (d...

Salt stress is an effective way to enhance the accumulation of phenolic compounds in soybean sprouts. In the present study, the effects of nitric oxide (NO) and γ-aminobutyric acid (GABA) on the biosynthesis of phenolic compounds in soybean sprouts under NaCl stress were investigated. Results showed that activities of three key enzymes involved in...

NaCl stress causes oxidative stress in plants; γ-aminobutyric acid (GABA) could alleviate such abiotic stress by enhancing the synthesis of phenolics, but the underlying mechanism is not clear. We investigated the effects of GABA on phenolics accumulation in soybean sprouts under NaCl stress by measuring changes in the content of physiological bioc...

The present study investigated the in situ production of vitamin B12 in eleven cereal, pseudo-cereal and legume materials by fermentation with Propionibacterium freudenreichii DSM 20271 and Levilactobacillus brevis (formerly Lactobacillus brevis) ATCC 14869.
