The convergence of sustainability and climate change has catalyzed the pursuit of inventive strategies for waste management and sustainable energy production. Hereby, we explored the effect of coupling biochar addition and thermal pretreatment in anaerobic mono-digestion and co-digestion of thermally pretreated thickened waste activated sludge (PTWAS) with food waste (FW). Six semi-continuous lab-scale digesters were operated for 161 days at various organic loading rates (OLR of 2, 3, 4 and 8 kgCOD/m/day) with and without biochar (BC) addition.

Although rice bran active peptide (RBAP) has potent antioxidant properties, its practical applications have been limited by its low bioavailability. In this study, we hypothesized that pH-responsive hydrogels prepared from the ionic gelation between chitosan and alginate could be a promising delivery system of short-chain peptides, like RBAP, for protecting them from chemical degradation during digestion and improving their functionality. The hydrogel beads retained RBAP in the gastric environment due to strong interactions between two biopolymers and RBAP, followed by a sustained release of more than 70 % peptide in the intestinal condition, thus improving its gastrointestinal stability.

Sea buckthorn, rich in nutrients and bioactive compounds such as phenolics, fatty acids, and vitamins, presents processing challenges due to its intense sourness and bland flavor. This study addresses key challenges in flavor enhancement and sourness reduction by evaluating the effects of pectinase treatment and inoculation sequences on the overall quality. Optimal malic acid degradation and antioxidant occurred when Schizosaccharomyces pombe (S.

The effects of wheat bran dietary fiber (WBDF) treated by air flow micro-pulverization on gelatinization, thermal, rheological, structural properties, and in vitro digestion of wheat starch (WS) were investigated. Different particle sizes of WBDF were obtained by conventional knife grinding and airflow micro-grinding. Compared with conventional knife grinding, the particle size of WBDF treated by air flow micro-pulverization decreased, the particle size distribution was concentrated at small particle sizes, the specific surface area increased, and the hydraulic and oil-holding power decreased, which was mainly related to the change of WBDF spatial structure and the increase of solubility.

Different kinds of proteins interact with the digestible lipids in various ways, affecting the adsorption behavior of proteins and digestion. The ordered porous layer interferometry (OPLI) system was constructed by the silica colloidal crystal (SCC) films used to monitor the real-time binding assessment between bovine serum albumin (BSA), casein, fibrinogen, and triolein. The OPLI system reflected the changes in protein mass on the SCC films in real time through the migration of the interference spectrum of the SCC films, which was converted into the changes in optical thickness (ΔOT) that can be monitored.
