Heterogeneity in Diameters of Protein Fibrils and Chitosan for a High CO/O Selectivity and Desired Mechanical Properties of Edible Bioplastic Films.

Edible bioplastics offer a possible approach with great potential to address the challenges of plastic and microplastic crisis and the issue of food waste. In the present study, in situ, induction of fibrillation of legume proteins within chitosan matrix is found to form edible bioplastic films with a high CO/O selectivity coefficient of ≈130. Desirable mechanical properties, including a high elongation at break of ≈230%, are realized to fabricate shopping bags, which can be filled with 5 kg of fruits.

Interfacial Protein Fibril Polymorphisms Regulate Adipose Expansion for Control of Obesity.

Obesity is becoming a worldwide pandemic. Interfacial engineering of food lipid is expected to inhibit diet-induced obesity without damage to the eating enjoyment brought by high-fat diets. Unfortunately, this strategy has not been achieved yet.

Salt-Promoted Fibrillation of Legume Proteins Enhanced Interfacial Modulus for Stabilization of HIPEs Encapsulating Carotenoids with Improved Nutritional Performance.

The thermal acidic-treatment-induced fibrillation of legume proteins isolated from cowpea and mung bean was demonstrated to be promoted by salt. Worm-like thin prefibrilar intermediates were formed in low salt concentrations (0-75 mM), which twisted to be the thick and mature amyloid-like fibrils with multistrands as the salt content was elevated (150-300 mM). Absorption of the fibrils fabricated in high salt concentrations to the oil/water interface constructed the protein layer with a significantly higher interfacial modulus compared with the one formed by the fibrils fabricated in low salt concentrations.

Lonicera japonica polysaccharides alleviate D-galactose-induced oxidative stress and restore gut microbiota in ICR mice.

Lonicera japonica polysaccharides (LJPs) exhibit anti-aging effect in nematodes. Here, we further studied the function of LJPs on aging-related disorders in D-galactose (D-gal)-induced ICR mice. Four groups of mice including the control group, the D-gal-treated group, the intervening groups with low and high dose of LJPs (50 and 100 mg/kg/day) were raised for 8 weeks.
