Problems solved by technology

However, the essence often contains a variety of ingredients, which are easy to volatilize and are sensitive to light and heat, which makes the service life of the essence short
[0003] By embedding the essence, the essence is wrapped inside the wall material to obtain microcapsules, which is beneficial to improve the service life of the essence. At present, the preparation method of microcapsules is spray drying method, air suspension method, complex coagulation, orifice coagulation, etc. Among them, the spray drying method is used more, but it is easy to cause the loss of essence
[0004]And for essence microcapsules, generally one type of essence is embedded in the microcapsules. The different components of different ingredients will easily cause different embedding effects, affect the compactness of microcapsules, and cause thermal stability and aroma retention time to decrease

Abstract

The invention relates to the technical field of essence, in particular to an oily essence microcapsule and a preparation method thereof. Comprising the following steps: preparing a water phase; preparing an oil phase; preparing a wall material; preparing a curing liquid; and preparing the microcapsule. The preparation method provided by the invention can be used for preparing the oily essence microcapsule, and the oily essence is treated, so that various oily essence can be embedded in the microcapsule together, the mixing of the essence is avoided, and the mixed fragrance is realized. By controlling the concentration of the sodium alginate in the wall material and selecting the proper capsule wall material to act together with the sodium alginate, the compactness of the wall material of the pre-hole-sharpening powder is improved, the embedding stability of the pre-hole-sharpening powder is improved, and the loss of the essence in the preparation process is reduced. The prepared microcapsule powder has low water content and good smoothness and fluidity, is prevented from being damaged by heat and the like, and improves the retention rate of aroma.

Description

technical field [0001] The invention relates to the technical field of essence, and more specifically, the invention relates to a preparation method of oily essence microcapsules and the microcapsules. Background technique [0002] Flavor is a kind of substance with fragrance, which can be used for daily use, food or other purposes. According to solubility, it can be divided into two categories, namely water-soluble (including alcohol-soluble) and oil-soluble. However, the essence often contains a variety of ingredients, which are easy to volatilize and are sensitive to light and heat, which makes the service life of the essence shorter. [0003] By embedding the essence and wrapping the essence inside the wall material to obtain microcapsules, it is beneficial to improve the service life of the essence. At present, the preparation methods of microcapsules include spray drying method, air suspension method, complex coagulation, orifice coagulation, etc., among which The spr...
