Wolfberry (Lycium barbarum L.) is a medicinal herb with anti-aging and neuroprotective effects. The purpose of this study was to explore the enhanced neuroprotective effects of wolfberry water extract (RW)， and brown wolfberry water extract (BBW). The reduced percentage of reducing sugar in BBW was shown to be 62.8%， 64.3%， 39.8%， and 11.6% for glucose， fructose， maltose， and lactose compared to those of RW， as well as free amino acids. And the contents of total phenols and total flavonoids were increased by 62.0% and 33.1%. Melanoidins (1% ± 0.05%) were first isolated from BBW. RW and BBW increased anti-stress abilities (oxidative stress: 24.2% vs 35.7%， and heat stress: 10.9% vs 19.1%) while decreasing the ROS levels in vivo. RW and BBW reduced the rate of paralysis and odor cognitive deficits. At the same time， RW and BBW reduced the number of fluorescent spots of Aβ::GFP. The RW and BBW activated autophagy by upregulating the gene levels (bec-1， lgg-1， lgg-2， unc-51， vps-34， atg-5， atg-18， and sqst-1). Additionally， BBW promoted the nuclear-cytoplasmic ratio of DAF-16::GFP and fluorescence intensity of SOD-3::GFP by 39.4 fold and 1.16 fold. This study laid a new insight for exploring the Maillard reaction in improving the anti-AD activity of wolfberry.

Modification of food protein fibrils: During and after fibrillization

引用

food Science and Human Wellness 2024年

作者： Kefan Ouyang Hexiang Xie Hua Xiong Qiang Zhao Wenjun Wang State key laboratory of food Science and resources， Nanchang University Jiangxi key laboratory of Natural Products and Functional food， College of food Science and Engineering， Jiangxi Agricultural University

Fibrillization endows food proteins with anisotropic nanostructures， significantly enhancing their functional properties. The resultant food protein fibrils (FPFs) have garnered attention for their diverse applications across the food industry. However， the full potential of FPFs is hindered by inherent challenges， particularly their limited stability. This review critically examines the formation of FPFs in food processing， the new protein sources， and on the modification strategies of FPFs， thereby unlocking new avenues for FPF utilization in food processing. In particular， the strategies during and after fibrillization are highlighted. The first strategy is to modify the structure and function of protein fibrils by influencing fibrillization， such as through pretreatment， incubation conditions， nuclei induction， and ingredient interactions. The second strategy is to modify the mature FPFs by regulating their properties and interactions with other components. The review also discusses the potential applications and challenges of FPFs in food systems， such as food preservation， functional food design， and novel delivery carriers.

Effect of ellagitannin metabolites ellagic acid and urolithins A-D on the non-enzymatic glycation of human serum albumin and inhibiting mechanisms

food Science and Human Wellness 2024年

作者： Lu Zhang Chun-yan Peng Wen-na Zhou Fei-yan Lu Lin-ju Xu Qing-hui Wen Xing Xie Zong-cai Tu National R&D Center of Freshwater Fish processing， College of Life Science， Jiangxi Normal University State key laboratory of food Science and resources， Nanchang University

Effect of ellagitannins gut microbiota metabolites ellagic acid (EA) and urolithin A-urolithin D (UroA-UroD) on human serum albumin (HSA) glycation were firstly evaluated in this research. The inhibition mechanisms were investigated by methylglyoxal (MGO) trapping and radical scavenging ability assays， docking studies and Nano LC-Orbitrap-MS/MS technology. Results indicated that the inhibition of urolithins on HSA glycation was highly positive correlated with the number of phenolic hydroxy groups. Addition of UroD and EA could effectively enhance the content of free amino group， suppress dicarbonyl compounds and advanced glycation end-products (AGEs) formation， alleviated tryptophan and protein oxidation， inhibited HSA amyloid-like aggregation. They could also trap MGO and scavenge DPPH· and ABTS·+. Molecular docking indicated that EA and UroA-UroD interact with HSA mainly through hydrogen bound and hydrophobic interaction， among which two or three hydrogen bonds were formed. The number of glycation sites were reduced from 11 to 10， 10， 7， and 10， respectively， when 90 μmol/L of EA， UroA， UroC and UroD were added. However， weak inhibition was observed on UroA and UroB. These findings can provide scientific evidence for the application of ellagitannins-rich foods in alleviating diabetic complications.
