A kind of preparation method of oil-water two-soluble type rosemary antioxidant

Abstract

The invention provides a preparation method of an oil-soluble water-soluble type rosemary antioxidant. The preparation method comprises the following steps of S1, adding water for dissolving wall materials, and performing filtration so as to prepare a wall-material solution; pouring a rosemary medicinal extract which is dissolved into the wall-material solution for uniformly stirring so as to obtain a solution to be homogenized; and S2, separately performing first-class homogenizing and second-class homogenizing on the solution to be homogenized obtained in the step S1, and then performing drying and cooling so as to obtain the oil-soluble water-soluble type rosemary antioxidant, wherein the solution to be homogenized is prepared from the following components in percentage by mass: 20-30% of the wall materials, 10-15% of the rosemary medicinal extract and the balance being water, and the wall materials are prepared from the following raw materials in percentage by mass: 65-85% of maltodextrin, 10-20% of beta-cyclodextrin or hydroxymethyl chitosan and 1-15% of sodium carboxymethyl cellulose or xanthan gum. The antioxidant provided by the invention can be mixed and dissolved in a water system, facilitates packaging and storage, and besides, has excellent antioxidation effects.

Description

technical field [0001] The invention belongs to the technical field of antioxidant embedding, and more specifically relates to a method for preparing an oil-water two-soluble rosemary antioxidant. Background technique [0002] Rosemary is a spice plant with a long history, which contains a variety of antioxidant phenols. [0003] Among them, the high-efficiency antioxidant substances are bisphenol diterpenes. Scientific evidence shows that carnosic acid and carnosol are the main active ingredients, and others include rosmanol. [0004] Rosemary antioxidants can be divided into fat-soluble and water-soluble. The main active ingredient of fat-soluble antioxidants is carnosic acid, which is used in foods such as oils and fats, dairy products, oil-rich foods, candies, and baked goods. Its function is to prevent oxidative deterioration of oils and food oxidative discoloration. Because of its excellent thermal stability, it can withstand high temperatures from 190°C to 240°C, so...

AI Technical Summary

Problems solved by technology

[0005] The existing rosemary oil preparation antioxidant can only be dissolved and dispersed in the oil state, and mainly has the following deficiencies: 1. Its scope of application is greatly limited, and its practicability is also greatly reduced, and it is not conducive to transportation and packaging

[0006] 2. In the prior art, oil preparations of other antioxidant products are also prepared into water-oil miscible systems, but the antioxidant performance of related antioxidant products after treatment is reduced

[0008] At present, there is no product and method that treats the oil preparation rosemary antioxidant to obtain oil-water miscibility
