Problems solved by technology

In addition, the complex coacervation method is also a means of vitamin E microencapsulation, but the cost of the wall material used is usually high, the process is relatively complicated, and the crosslinking agent used is often toxic.
The cross-linking method is also a method of vitamin E microencapsulation. At present, there are many foreign patents on the preparation of fat-soluble vitamin microcapsules by the cross-linking method, but the process of this method is relatively complicated, and there are many factors to be considered in the cross-linking process. still improving

Abstract

A vitamin E microcapsule preparation method belongs to the technical field of preparation of controlled-release microcapsule for food additives and bioactive substances. The vitamin E microcapsule preparation method can improve the stability of vitamin E and amplify the application range. The method comprises the following steps: selecting chitosan and maltodextrin as wall material, selecting soybean lecithin (P powder) and Tween-80 as the composite emulsifying agent; and synthesizing vitamin E microcapsule by spray drying. The vitamin E microcapsule has embedding rate up to 92.45%, retention rate up to 91.73%, and water content lower than 3%, and has wide application prospect in the fields of bread or snack products, beverages, biscuits, health products and nutrient fortified food, etc. The method has the advantage of low cost and simple process, can meet the environmental protection and practical requirement.

Description

technical field [0001] The invention discloses a method for preparing vitamin E microcapsules, belonging to the technical field of microcapsule preparations for controlled release of food additives and bioactive substances. Background technique [0002] Vitamin E is an essential nutrient for the human body. It is a powerful and effective free radical scavenger, which can protect the body's cell membrane and life macromolecules from free radical attacks. It is a kind of efficient and safe natural antioxidant, which can delay aging. , prevention and treatment of cardiovascular disease, anti-tumor has a good effect. Natural vitamin E is superior to synthetic vitamin E in terms of nutrition, physiological activity, and safety. With the in-depth study of nutrition and pathology, more new functions of vitamin E have been continuously discovered and confirmed. People's demand for vitamin E is increasing, and its role has attracted more and more attention. [0003] Vitamin E is an...
