Egg yolk immunoglobulin (IgY) is valuable against intestinal infections, however, its activity will be affected by the gastrointestinal fluid of livestock and poultry storage environment. Therefore, we prepared IgY-loaded sodium alginate/chitosan/sodium alginate microcapsules (IgY-loaded SA/CS/SA MCs), aiming to improve poor tolerance IgY in tract as well instability performance, so performance application. In this experiment, was used core material, chitosan were wall preparation carried out extrusion method. The results showed that encapsulation efficiency MCs highest (94.84%) when concentration 200 mg/mL, CS 0.8%, solution pH value 5.0 (P<0.05). After freeze-drying, shape group T1 more regular, with an average particle size 2.159 mm compressive strength stability simulated gastric (pH 2.0) significantly enhanced compared NC, T2, T3 groups (P<0.05), improved antibacterial properties increased alkalinephosphatase content T2 addition, stored at room temperature (23±2°C) for 8 weeks, maintained >70% fluids significant inhibition E. coli SG vitro.

Oligosaccharides, as a wide type of polysaccharide, have broad antimicrobial spectrum and promote development plant growth stimulants. To investigate the regulation effects different oligosaccharides on dynamic changes chlorophyll content, leaf fluorescence, root activity morphology, chloroplast ultrastructure, well yields yield components strawberry cucumber, typical greenhouse experiments were conducted over two years (2021–2022). The experimental plants foliar sprayed with tap water (CK), chitosan oligosaccharide (CSOS), mixed (MixOS) five times before flowering. conventional management (CM) was control. findings present study suggest that application MixOS has greatest delayed senescence, well-developed roots, higher fruit productions cucumber. Exogenous resulted in significant increases SPAD values, maximum photochemical efficiency (Fv/Fm), quenching coefficiency (qP); they increased by 1.94–28.96%, 5.41–33.89%, 9.93–62.07%, compared to CSOS, CM, CK treatments, respectively. orderly steady structure thylakoids chloroplast, randomly distributed starch grains, could be clearly observed treatment, while non-photochemical (NPQ) correspondingly reduced 19.04–45.92%. Meanwhile, remarkable promotion surface morphology indicators (i.e., length, area, average diameter, volume) when exposed total cucumber all 12.40–25.57%. These mainly coordinated shoot, which leads improved

The study focuses on the efficient production of curdlan β-1,3-glucooligosaccharides (CDOS) through microwave-assisted hydrothermal hydrolysis curdlan. optimal condition was identified as 170 °C and 30 min, resulting in a liquefaction yield over 96%, mainly contains CDOS along with minor amounts glucose 5-hydroxymethylfurfural (5-HMF). Oligosaccharides low degree polymerization (DP), specifically DP2 to DP6, were isolated. yields for DP6 15.87%, 8.33%, 6.00%, 3.13%, 1.83%, respectively, purities 70%. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) analysis demonstrated that dense triple helix structure crystalline disrupted during degradation. Additionally, at concentration 2.5 mg/mL partially inhibited growth
