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.

The QuEChERS extraction technique is a pretreatment technique that has been rapidly applied in recent years and is widely used in the field of pesticide residues with many advantages. This technique is based on solid phase extraction (SPE), which uses the interaction between adsorbent and impurities in the matrix to achieve the purpose of purification. The method has easier operation and better purification effect than SPE. In this paper, the research progress of the QuEChERS technique in pesticide residue detection in different fields in recent years and its future development were reviewed, hoping to provide reference for further development and utilization of the QuEChERS technique in pesticide residue detection in the future.
