- Enzymatic Synthesis and Antioxidant Activity of 1-Caffeoylglycerol Prepared from Alkyl Caffeates and Glycerol
-
Caffeic acid (CA) as a strong antioxidant has lower solubility in nonpolar media, which limits its application in the food industry. To increase the lipophilicity of CA, 1-caffeoylglycerol (1-CG) was synthesized by lipase-catalyzed transesterification of

- Water-soluble caffeoyl structural grease, and preparation method and application thereof
-
The invention belongs to the field of structural grease, and discloses water-soluble caffeoyl structural grease, and a preparation method and application thereof, in particular application thereof as an antioxidant. The chemical name of the water-soluble caffeoyl structural grease is 1-caffeoyl monoglyceride. The chemical structure is as shown in Formula (1). The invention also provides an enzymatic synthesis method. According to the method, an exchange reaction between caffeoyl acetate and glyceride is catalyzed by enzymes through a solvent-free system to prepare the 1-caffeoyl monoglyceride, so that the preparation of water-soluble caffeoyl derivatives is realized. The 1-caffeoyl monoglyceride is a new functional phenololipoid, has multiple physiological activities of caffeic acid, has higher antioxidant activity in both a water-soluble system and an alcohol-soluble system, and overcomes the defect of poor water solubility of the caffeic acid. Meanwhile, the 1-caffeoyl monoglyceride, serving as a potential natural water-soluble antioxidant substance, can be applied to the fields of emulsified food such as milk and functional grease and cosmetics, and has great economical and social values.
