Problems solved by technology

However, the preparation process requires chemical curing treatment, which affects the safety and quality of the product, and the product is prone to agglomeration when it is placed for a long time
[0006] Chinese patent publication CN101019838A reports a method for preparing linseed oil microcapsule powder by using starch sodium octenyl succinate, which uses a single wall material to embed and emulsify linseed oil, and only adds a vitamin E as an antioxidant, which is difficult to obtain. Guaranteed shelf life of linseed oil products
[0007] Due to the high content of unsaturated fatty acids in linseed oil, it is easy to oxidize and become rancid during processing and storage, not only the nutritional value will be greatly reduced and the smell will be unpleasant, and the peroxides, aldehydes and ketones produced at the same time will be harmful to the human body. influences

Abstract

The invention discloses a flaxseed oil microcapsule and a production method thereof. The core material of the flaxseed oil microcapsule is flaxseed oil, and the wall material is made of modified starch, maltodextrin and sodium caseinate. The production method comprises steps of adding the modified starch, the maltodextrin and the sodium caseinate to hot water with high-speed stirring until the the modified starch, the maltodextrin and the sodium caseinate are dissolved completely and forming a water phase; weighing and taking the flaxseed oil, adding vitamin E, rosemary and tea polyphenol step by step, stirring the mixture until the mixture is dissolved completely and forming an oil phase; conducting high-speed cutting for the obtained water phase by using a cutting machine, adding the obtained oil phase slowly and obtaining an emulsion; homogenizing the emulsion by using a high-pressure homogenizer; sterilizing the emulsion which is homogenized by using an ultra high-temperature sterilizing machine; and spraying and drying the sterilized and obtaining the flaxseed oil microcapsule. The embedding rate of the flaxseed oil microcapsule is more than 90%, the capacity of the flaxseed oil can reach 45%, the process is simple, the taste is special, the scent is obvious and the shelf life is long.

Description

technical field [0001] The invention relates to the technical field of deep processing and application of agricultural products, in particular to a production method of linseed oil microcapsules. Background technique [0002] Flaxseed oil, also known as linseed oil or linseed oil, is a drying oil obtained from flaxseed. The unsaturated fatty acid in linseed oil is more than 80%, among which the content of α-linolenic acid is as high as more than 50%. As edible oil, linseed oil has important physiological functions and high nutritional value. First of all, α-linolenic acid is an essential fatty acid for the human body, which cannot be synthesized in the human body. If it is deficient in the diet, it will cause α-linolenic acid deficiency; its metabolites EPA and DHA are the precursors of triene prostaglandins in the body and the brain, retina It can not only improve the function of the nervous system, promote learning and memory and behavioral activities, but also regulate ...
