This study investigated the suppressive effects of Armoracia rusticana (AR) and its three main glucosinolates on both free and bound heterocyclic amines (HAs)， along with their mechanisms of free radical quenching using density functional theory. Fish patties were supplemented with varying concentrations of AR (0.5%～1.5%) and glucosinolates (0.005%～0.015%)， showing a dose-dependent inhibition of HAs and concurrent elimination of free radicals and HAs intermediates. Glucobrassicin demonstrated the highest reactivity， which was verified by frontier orbit analysis and conceptual density functional parameters， consistent with experimental findings. Furthermore， the O-H bond connected to the sulfur atom of glucobrassicin possessed the smallest bond dissociation enthalpy (BDE) value， which indicated that this particular hydrogen atom is most susceptible to react with free radicals. Overall， AR and its glucosinolates， especially glucobrassicin， show promise as natural additives for improving food safety and quality.

High-carbohydrate(HC) diets decrease the intestinal levels of sodium acetate(SA) and sodium butyrate(SB) and impair the gut health of largemouth bass; however, SA and SB have been shown to enhance immunity and improve intestinal health in farmed animals. Thus, the present study was to investigate the effects of dietary SA and SB on HC diet-induced intestinal injury and the potential mechanisms in juvenile largemouth bass. The experiment set five isonitrogenous and isolipidic diets, including a lowcarbohydrate diet(9% starch)(LC), a high carbohydrate diet(18% starch)(HC), and the HC diet supplemented with 2 g/kg SA(HCSA), 2 g/kg SB(HCSB) or a combination of 1 g/kg SA and 1 g/kg SB(HCSASB).The feeding experiment was conducted for 8 weeks. A total of 525 juvenile largemouth bass with an initial body weight of 7.00 ± 0.20 g were used. The results showed that dietary SA and SB improved the weight gain rate and specific growth rate (P<0.05) and ameliorated serum parameters(alkaline phosphatase, acid phosphatase, glutamate transaminase, and glutamic oxaloacetic transaminase)(P<0.05). And, importantly, dietary SA and SB repaired the intestinal barrier by increasing the expression levels of zonula occludens-1, occludin, and claudin-7(P<0.05), reduced HC-induced intestinal damage, and alleviated intestinal inflammation and cell apoptosis by attenuating HC-induced intestinal endoplasmic reticulum stress(P<0.05). Further results revealed that dietary SA and SB reduced HC-induced intestinal fat deposition by inhibiting adipogenesis and promoting lipolysis(P<0.05). In summary, this study demonstrated that dietary SA and SB attenuated HC-induced intestinal damage and reduced excessive intestinal fat deposition in largemouth bass.

Fresh wet noodles(FWN) are popular staple foods due to its unique chewy texture and favorable taste. However,the development of FWN is limited by its short shelf life and high browning rate. It has been found that the quantity of original microorganisms in wheat flour produced by traditional method is relatively high, which is detrimental to the processing quality and storage stability of FWN. Consequently, it becomes imperative to decrease microorganisms in wheat flour. Microwave treatment has been regarded as a promising method in the food industry due to its potential in inhibiting microbial growth and inactivating enzymes without causing adverse effect on the food quality. This study aims to investigate the effects of microwave treatment of wheat kernels under different powers(1, 2, 3, 4, 5 kW) on the physicochemical properties of wheat flour and the quality of FWN. The results revealed that microwave treatment had a significant effect on microbial inhibition and enzyme inactivation, wherein the total plate count(TPC) and yeast and mold counts(YMC) decreased by 0.87 lg(CFU/g) and 1.13 lg(CFU/g) respectively, and PPO activity decreased from 11.40 U to 6.31 U. The dough quality properties, such as stability, extensibility, and starch viscosity, improved significantly under different microwave conditions. Confocal laser scanning microscopy(CLSM) images indicated that starch and proteins aggregated gradually in treated flour, altering rheological properties of dough. From the results of scanning electron microscopy(SEM), microwave treatment led to the appearance of disrupted structure in the gluten proteins, but the secondary structure of proteins altered slightly. Rheological properties of dough confirmed that the microwave treatment greatly affected processing characteristics of wheat flour products, with significant advantageous consequences on product quality, especially for textural properties of FWN. Furthermore, FWN darkening could be inhibited noticeably aft
