Abstract

Conjugate linoleic acid or cnojugate linoleate microcapsule consists of wall material, capsule core, assistant, surfactant and plasticizer. Capsule core is added into wall material water solution and emulsified while adding assistant, surfactant and plasticizer; and the microcapsule product is obtained through spray drying. Great amount of experiment shower that the product has high antioxidant performance and high store stability, can mask bad smell, avoid mutual effect of different incompatible food components and decrease degradation reactions and reach controlled release. 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 of conjugated linoleic acid or conjugated linoleic acid ester prepared by spray drying method 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 ph...
