Summary: Lotus flower polysaccharide (LFP) and lotus seedpod polysaccharide (LSP) were separated and characterized in this study. Both polysaccharides exhibited antioxidant capacity and enhanced cellular proliferation without cytotoxicity. Furthermore, LFP and LSP were able to induce autophagy in cells.

Summary: The lotus is the largest aquatic vegetable in Asia. The lotus seedpod is an inedible part of the mature flower receptacle, but its polysaccharide content has been less studied. Two medium-sized HG pectins, LSP-1 and LSP-2, were purified from the seedpod and their structures were elucidated. They possess certain antioxidant and immunomodulatory activities, but esterification of HG pectin negatively affects these activities. The degradation of LSPs by pectinase followed the Michaelis-Menten model. The abundance of lotus seedpods makes them a promising source for polysaccharide isolation, with potential applications in the food and pharmaceutical industries.

Summary: In this study, a YOLOv5-lotus method is proposed to accurately detect overripe lotus seedpods. Through the use of an improved YOLOv5 network model and a coordinate attention module, the detection accuracy is significantly improved. Case studies and comparisons demonstrate the effectiveness and superiority of the proposed approach, providing a foundation for the development of automated harvesting equipment.

Summary: This study prepared lotus seed protein hydrolysate (LSPH) using Flavourzyme and evaluated its antioxidant activities. The results showed that the low molecular weight fragments generated from Flavourzyme hydrolysis of lotus seed protein have potential as nutraceutical or health promoting supplements due to their antioxidant activities.

Summary: This study aimed to investigate the safety and probiotic properties of Lactobacillus paraplantarum LS-5 isolated from traditional northeastern sauerkraut, and to assess the antioxidant capacity of different solvent extracts of L. paraplantarum LS-5-inoculated sauerkraut. The probiotic characteristics of L. paraplantarum LS-5 were determined, including good survival ability under artificial gastrointestinal conditions, antagonistic activity against various pathogens, non-biogenic amines, antibiotic susceptibility, and non-hemolytic. The sauerkraut alcohol extract of L. paraplantarum LS-5-inoculated sauerkraut showed significantly higher 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonate (ABTS) radical scavenging activity and ferric reducing antioxidant power (FRAP) compared to water extracts.

Summary: This study prepared covalent conjugates of pumpkin seed protein isolate (PSPI) and different polyphenols (epigallocatechin gallate (EGCG), chlorogenic acid (CA), and gallic acid (GA)) at pH 9.0 to develop covalent microparticles for protecting the stability of polyphenols. The results showed that polyphenols covalently bonded with PSPI, resulting in a more regular and stable structure. EGCG-PSPI conjugates exhibited the highest polyphenol-bound equivalents and the most stable structure. EGCG-PSPI microparticles effectively increased the retention rate of free radical scavenging activity under different conditions. Therefore, polyphenol-PSPI covalent conjugate microparticles could be used as efficient carriers for stabilizing the DPPH radical scavenging ability of polyphenols.

Summary: This study examined the metabolite profiling of COP1 mutated rice seed (yel-mutant) and found that the total fatty acid content decreased by more than 50% in the yel-mutant compared to the wild-type. The yel-mutant of both cultivars showed significantly higher flavone contents than their wild-type. This study provides useful information for colored rice breeding by revealing the detailed biofunctional metabolic profile under COP1 mutation.

Summary: The conditions for determining the antioxidant properties of cyclitols, flavanones, and glutathione have been identified. The low antioxidative properties of cyclitols compared to flavanones and glutathione were revealed. However, the methyl-ether derivatives of cyclitols showed a significant increase in the antioxidative properties of glutathione.

Summary: The novel free radical scavenger ML-Ti3C2Tx MXene exhibits high scavenging efficiency due to its intrinsic reducing property, rather than hydrogen donation ability from surface functional groups. The observed scavenging activity is attributed to the reducing property of ML-Ti3C2Tx, as compared to other materials.
