Abstract

The invention provides a preparation method of an amomum villosum essential oil microcapsule. The preparation method mainly comprises the following steps: by taking amomum villosum essential oil as a core material and one or more of an inulin-lysozyme aqueous solution, an inulin-chitosan aqueous solution, a pectin-lysozyme aqueous solution and a pectin-chitosan aqueous solution as wall materials, adjusting the pH value of a system to 3-10 according to a mass ratio of the amomum villosum essential oil to the nanoparticle aqueous solution of 2: 1-1: 2, stirring at a high speed of 800-1600 r / min to obtain a pickering emulsion product, carrying out ultrasonic dispersion for 30-60 minutes under the power of 200W, and then carrying out spray drying to obtain the amomum villosum essential oil microcapsule. The amomum villosum essential oil microcapsule prepared by the method not only can protect the activity of the amomum villosum essential oil and realize slow release of the amomum villosum essential oil, but also has biological activity of inducing apoptosis of human hepatoma cells HepG2, and can realize wider application of the amomum villosum essential oil in the fields of food, health care products and medicines.

Description

technical field [0001] The invention belongs to the technical field of microcapsule preparation, relates to a method for preparing amomum essential oil microcapsules, and belongs to the technical field of food processing. Background technique [0002] Amomum ( Amomum villosum Lour.), a perennial herb belonging to the Zingiberaceae cardamom, is a medicinal and edible raw material widely distributed in Fujian, Guangdong, Guangxi and Yunnan in China. It has the effects of dispelling dampness and appetizing, warming the spleen and stopping diarrhea, regulating qi and anti-abortion. It is mainly used clinically for the treatment of dampness and turbidity, abdominal distension without hunger, spleen and stomach deficiency and cold, vomiting and diarrhea, pregnancy obstruction, fetal movement and other diseases. , and have a better effect. In recent years, studies have found that amomum has rich pharmacological activities, especially in gastrointestinal protection, analgesia, an...
