Abstract

Cyclodextrin coated microcapsule consists of coated matter, cyclodextrin and antioxidant. The coated matter is added into cyclodextrin or its solution while adding antioxidant and stirring and the microcapsule product is obtained through cooling, vacuum filtering and freeze drying. The product has the same physiological activity as conjugate linoleic acid and its derivative as well as high antioxidant performance and high stability. The present invention may be used in health food, food additive and feed additive and has health functions of anticancer, resisting arteriosclerosis, regulating metabolism, strengthening body's immunity, regulating blood sugar, etc.

Description

technical field [0001] The invention relates to a microcapsule product of conjugated linoleic acid and its derivatives prepared by cyclodextrin inclusion Background technique [0002] Microencapsulation technology (microencapsulation) is a rapidly developing new technology today, which refers to the encapsulation of capsule core (core) substances such as oil, spices, condiments and other food ingredients or food additives with wall material (encapsulation) substances, so that It is isolated from the external environment and released at an appropriate time. [0003] So far, the methods of microencapsulation can be divided into three categories: 1. The method of preparing microcapsules by applying chemical principles, such as interfacial polymerization method, in-situ polymerization method, etc.; 2. The method of preparing microcapsules by applying physical and chemical principles, such as Single coacervation method, complex coacervation method, oil phase...
