Milk fat globules (MFG) are the primary source of energy and functional factor in dairy-based products. To evaluate the suitability of commercial MFG substitutes for infant and adult consumers， the lipolysis properties and regulatory factors in digesting bovine， caprine， and human MFG were compared. The lipolysis kinetic models of bovine and caprine MFG are comparable， with bovine MFG displaying the highest degree of lipolysis (50.21%) during gastric digestion in infants， resulting in the production short-chain saturated fatty acids. Caprine MFG has a high rate of lipolysis due to its weak phospholipid-glycoprotein layer， which is prominent in both infants’ and adults’ digestion. The effects of consuming bovine and caprine MFG for adults are comparable in terms of lipolysis properties and nutritional value of fatty acid. After gastrointestinal digestion， human MFG has the highest digestibility (93.98%). The advantages of human MFG include its phospholipid structure， exogenous lipase， and lipolysis-regulating proteins. This study provides recommendation for the selection of milk fat substitutes and improvements in commercial dairy.

Self-healable and mechanically robust supramolecular-covalent poly(oxime-urethane) elastomers with information encryption via hydrogen bonds and coordinate interactions

引用

Science China Chemistry 2024年

作者： ting Ye Jialing Tan Tao Wu Fang Zhang Shaoyu chen Chaoxia Wang College of Textile Science and Engineering Jiangnan University School of Fashion and Textiles The Hong Kong Polytechnic University

Self-healing polyurethane-elastomers are highly desired in various fields. However, there is often a trade-off between mechanical properties and dynamic self-healing due to the mutually exclusive mechanism. Herein, we develop a self-healable and mechanically robust poly（oxime-urethane） elastomer（Zn-DAPU） to circumvent this inherent trade-off by incorporating zincpyridinyl cross-links into the hydrogen bonding and dynamic oxime-urethane supramolecular-covalent hybrid network. Benefiting from the synergistic strengthening of H-bonding and coordinate interactions, Zn-DAPU network performs tunable toughness with metal ion concentration change, which improves 345.2% and reaches 82.2 MJ m-3, with robust tensile strength of 22.8 MPa, Young's modulus of 37.1 MPa, and satisfactory elongation of 815.7%. The healing efficiency can be reached at 91.7% with a restored toughness of 75.4 MJ m-3at 80 °C for 10 h. Furthermore, zinc-contained networks exhibit photolysis behavior due to the homolytic cleavage of N–O bonds in oxime-urethane moieties, which can be functionalized further with fluorescamine as the specific information encryption coating with quick response codes（QRs） upon polyester fabric. This work provides valuable guidance towards the development of high-performance self-healing polyurethane and wearable functional materials.
