Abstract

The invention discloses a preparation method of a ginseng nano-microcapsule in favor of human body absorption. The method includes: conducting jet milling treatment on ginseng to obtain micron-sized ginseng granules, performing sieving and then carrying out supercritical CO2 fluid extraction technical treatment to obtain a ginseng extract; taking the ginseng extract and an emulsifier as core materials, using sodium alginate and chitosan as wall materials, and adding the ginseng extract, the sodium alginate, the chitosan and the emulsifier into water, stirring them uniformly, and performing nanometer ultrahigh pressure homogenizing treatment. The emulsifier is molecular distillation monostearin. Specifically, the core materials and the wall materials are in a mass ratio of 1:0.5-3, the sodium alginate and the chitosan are in a mass ratio of 1:1-5, the emulsifier accounts for 0.05-0.5% of the total solid mass, and the mass ratio of solid to liquid is 10-30%. The obtained solution is subjected to spray drying, thus obtaining the ginseng nano-microcapsule. The method provided by the invention is conducive to absorption of nutrients by the human body, can improve the bioavailability of ginseng, and enhances the activity.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a preparation method of ginseng nano-microcapsules. Background technique [0002] Ginseng is the dry root of Araliaceae plants. "Shen Nong's Materia Medica" records that ginseng "mainly nourishes the five internal organs, calms the spirit, calms the soul, stops panic, eliminates evil spirits, improves eyesight, improves intelligence, and makes light body and prolongs life after long-term use." Ginseng Chemistry The composition is complex, containing saponins, fatty acids, volatile oils, amino acids, sugars, flavonoids, vitamins, etc. Among them, saponins are considered to be the main active ingredients in ginseng. Function and immune function and anti-fatigue and other aspects have a good effect. [0003] There are two types of ginseng commonly eaten in my country: (1) Raw sun-dried ginseng, also known as white ginseng, is processed from fresh ginseng through washing, sun-drying, ...
