Peony seed oil microcapsule and preparation method thereof

Abstract

The invention discloses a peony seed oil microcapsule and a preparation method thereof. The peony seed oil microcapsule provided by the invention is prepared from the following substances in mass ratio: a core material: peony seed oil; the wall material comprises a wall material A and a wall material B; the wall material A is maltodextrin; the wall material B is selected from one of soybean protein isolate, whey protein isolate and sodium caseinate; the mass ratio of the wall material B to the wall material A is (2: 1)-(1: 2); the mass ratio of the wall material to the core material is (2: 1)-(1: 2). The invention also provides a preparation method of the peony seed oil microcapsule. The peony seed oil is embedded through the composite wall material, and the preparation process conditions of the peony seed oil microcapsule are optimized by utilizing an orthogonal experiment on the basis of a single factor experiment, so that the optimal embedding conditions are obtained. After the peony seed oil is subjected to microencapsulation, nutritional ingredients of the peony seed oil can be effectively reserved, and oxidation can be delayed to a great extent.

Description

technical field [0001] The invention relates to microcapsules and a preparation method thereof, in particular to peony seed oil microcapsules and a preparation method thereof. Background technique [0002] As a new edible oil resource, peony seed oil has a content of unsaturated fatty acids up to 90%, of which α-linolenic acid content can reach 40%. As an essential fatty acid for the human body, α-linolenic acid can synthesize a variety of functional components in the human body, which has the functions of lowering blood fat, lowering cholesterol, and preventing cardiovascular and cerebrovascular diseases. Therefore, its application prospects are very broad. However, due to the extremely easy oxidation of peony seed oil, the product types of peony seed oil on the market are relatively single, and the resources of peony seed oil have not been efficiently utilized. And the current research mainly focuses on the refining technology and antioxidant activity of peony seed oil. ...

AI Technical Summary

Problems solved by technology

There are detailed and sufficient studies on functional oils at home and abroad, such as fish oil, Antarctic krill oil, and linseed oil, but there are relatively few studies on the microencapsulation of peony seed oil and the evaluation of in vitro and in vivo biological properties after microencapsulation. few
