Other sources of fat are necessary and crucial for infants while the breastfeeding is not possible, desirable or sufficient. There is enough scientific evidence that suggests the composition and distribution of the fatty acids affect the absorption of the fat in infants greatly, which influences the growth and health of infants. However, the composition and distribution of the fatty acids in certain fat such as cow milk fat or vegetable oil are different from those in human milk. So as to mimic human milk fat composition and structure, a series of human milk fat substitutes （HMFS） have been developed through enzymatic interesterification reaction during recent years This review described current trends in the production of HMFS, discussed the significance and methods of preparing HMFS and the problems and put forward potential solutions about this kind of product.展开更多

In this review, the recent developments by 2019 in the field of enzymatic modification of oils rich in omega 3 PUFAs have summarized. Several different products, such as structured lipids with a variety of FA compositions, nutritional aspects, omega 3 PUFA concentrates and phospholipids,have discussed from the point of process technology as well as possible applications. Enhancing omega 3 PUFA content in diet involves a number of strategies aiming to modify the content of such FAs in fats and oils. Due to the mild reaction conditions used, especially the lipase specificity, the position as well as content of omega 3 PUFAs in lipid molecules being of importance from the point of bioavailability, enzymatic processing of omega 3 PUFA oil is safe, efficient and preferred over chemical treatments.展开更多

文摘Human milk fat （HMF） is the component that supplies the highest fraction of the infant＇s required dietary energy.
