Article Abstract

The present study has developed a novel, eco-friendly method for the modification of potato starch by incorporating ultrasonic pretreatment, enzymatic hydrolysis, and oxidation with hydrogen peroxide. The technical parameters of the modification were optimized through response surface methodology to give optimum conditions. The results showed that the combination of ultrasound and enzyme disrupted the microstructure and crystalline structure of the starch granules, thus allowing for easier penetration of modifying agents and increasing the reactivity of the starch. Additionally, this starch exhibited higher thermal stability, with improved rheological properties compared to conventionally modified starch. This combined modification approach further reduced agglomeration of starch granules usually achieved by single-agent modification and increased the solubility of starch. Thus, this eco-friendly method is effective for the modification of potato starch.

Maize (Zea mays L.) is one of the world's most widely cultivated and economically important cereal crop, serving as a staple food and feed source in over 170 countries. However, its global productivity is threatened by late wilt disease (LWD), a disease caused by Magnaporthiopsis maydis, that spreads through soil and seeds and can cause severe yield losses.

Over recent decades, the indiscriminate use of antibiotics in animal production to enhance product quality and maximize economic returns has raised critical concerns. However, antibiotic misuse has led to the development of antimicrobial resistance in livestock and poses substantial health risks to humans through drug residue accumulation. In response, nations globally have progressively implemented bans on antibiotic inclusion in animal nutrition, redirecting scientific attention toward antibiotic-free feed additives that maintain or enhance animal health performance.

In this study, aloe emodin and β-d-glucose pentaacetate were added into potato starch/polyvinyl alcohol for the construction of colorimetric/fluorescent dual-pass intelligent response labels. Inspired by the lotus leaf structure, retained the advantages of the label itself and solved the hydrophilic problem of the label, and further developed a multi-functional dual-channel smart label with hydrophobicity and self-adhesion. The water contact angle of the prepared T-AEB label was 120.

Polysaccharide copolymers Conjuates have surfaced as a versatile foundation in the development of advanced smart drug delivery systems, owing to their inherent biocompatibility, biodegradability, and capacity for chemical modification. This review brings into focus the recent advances in co-polymeric drug delivery systems based on naturally occurring polysaccharides like chitosan, alginate, dextran, hyaluronic acid, pullulan, guar gum, xanthan gum, agarose, gellan gum, and starch. Their structural malleability and functionalization capabilities are emphasized to engineer therapeutic payload stability, bioavailability, and controlled release.
