Abstract

The invention relates to a preparation method for phytosterol ester microcapsules, which comprises the following steps: firstly, taking Arabic gum and maltodextrin as wall materials, adding hydrophilic emulsifier, and dissolving by heating in a water bath, so as to prepare an aqueous phase wall material solution; then adding oleophylic emulsifier into phytosterol ester to prepare an oil phase core material solution; further, mixing the core material solution and the wall material solution under the ultrasonic-assisted condition, and emulsifying and homogenizing to acquire a homogeneous emulsion system; finally spray drying the emulsion, and screening to acquire powdery homogeneous phytosterol ester microcapsule products. The phytosterol ester microcapsule products prepared through the method have embedding rate more than 94%, solubility more than 95%, and fragrance; oxidation stability of the phytosterol ester is improved, and functional activity and nutrition of the phytosterol ester are favorably conserved; meanwhile, the method enables the phytosterol ester to transform from a liquid to a more stable solid, so that shelf life is prolonged, transportation and storage are facilitated, bioavailability of the phytosterol ester is improved, and the market demand is met more satisfactorily.

Description

technical field [0001] The invention belongs to the technical field of oil deep processing, and in particular relates to a preparation method of phytosterol ester microcapsules. Background technique [0002] Phytosterol esters are obtained by esterification of phytosterols and fatty acids. Since the main components of phytosterols are β-sitosterol, stigmasterol, brassicasterol and campesterol, phytosterol esters are mainly composed of β-sitosterol esters, Composition of stigmasterol ester, brassicasterol ester and campesterol ester. Sterol esters can be absorbed by the human body and transformed into sterols and fatty acids, which have a better cholesterol-lowering effect than free phytosterols. Now it has been recognized as a functional oil with health care function, and it has been continuously developed and utilized in the fields of food and medicine. At present, phytosterol esters are mainly transported and stored in the form of barrels. Because phytosterol esters are ...
