Summary: Starch, a copolymer with unique physicochemical characteristics, has limitations in food applications due to its undesirable properties. Different modification methods are used to improve its performance and expand its application. The addition of small amounts of polysaccharides affects the properties of starch pastes and gels, with factors such as starch type, polysaccharide type, and preparation methods playing a role. This review discusses the changes in starch properties and the mechanism of polysaccharide action on starch after modification.

Summary: In this study, a series of cellulose ester-graft-polylactide copolymers were synthesized using the ionic liquid 1-ethyl-3-methylimidazolium diethylphosphate as the reaction medium. The structures and compositions of the copolymers were controlled by varying the feed ratio of carboxylic anhydride and L-lactide. The copolymers exhibited enhanced thermal stability and thermoplasticity due to the intermolecular interactions. The mechanical properties and biodegradability of the copolymers were investigated using homogeneous cast films and enzymatic degradation.

Summary: Swelling behavior involves the process of starch granules absorbing enough water to increase the viscosity of starch suspension under hydrothermal conditions, which is important in starch research. The changes in starch granules during the swelling process are crucial in predicting their functional properties in food processing. This article comprehensively reviews the mechanism of starch swelling, its influencing factors, and its relationship with the pasting, gelling, and digestion characteristics of starch.

Summary: Starch can be efficiently converted into formates using N-formyl imidazole, which are soluble in polar aprotic solvents, resistant to hydrolysis, and not meltable. Thermoplastics can be produced by converting starch formates with long-chain fatty acids, resulting in mixed esters with melting temperatures mainly dependent on the amount of laurate ester moieties.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
