Embodiment 2

[0009] Prepare acid-processed gelatin (type A) homogeneous solution (0.07%) at pH 4.5 and hydroxypropyl distarch phosphate solution (0.85%) at pH 4.5 with acetic acid solution (1% v / v) at room temperature for subsequent use; Add a compound emulsifier (monoglyceride: sucrose ester = 1:8) (0.75%) to a certain volume of green thorn fruit oil while stirring, stir in a water bath at 50°C for 30 minutes, and add dropwise to the prepared gelatin solution Medium (the ratio of green thorn fruit oil to gelatin is 1:4, v / w), stir for 30 minutes and shear evenly at 2000 r / min to obtain a uniform emulsion; add the prepared The hydroxypropyl distarch phosphate solution was stirred for 20 minutes, then stood still for 5 hours, centrifuged at 10,000 rpm for 10 minutes at 25°C, collected the formed particles, and dispersed the obtained wet particles in distilled water. Then dry at room temperature under negative pressure, and store under dry conditions at 25°C. The core material of the micros...

Abstract

The invention provides a prinsepia utilis royle fruit oil microsphere and a preparation method thereof. The prinsepia utilis royle fruit oil microsphere prepared by the preparation method is uniform in shape and has a smooth surface. The preparation method comprises the following steps: respectively preparing an acid-process gelatin (A type) homogeneous solution with pH being 4-5 and a hydroxy propyl distarch phosphate solution with pH being 4-5 by using an acetic acid solution (1%v/v) for later use; adding a compound emulsifier (containing monoglyceride and sucrose ester in a ratio being 1:8) into a certain volume of prinsepia utilis royle fruit oil under the stirring condition, stirring for 30 minutes and dropwise adding into the prepared gelatin solution, stirring and uniformly shearing to obtain a homogeneous emulsion; adding the prepared hydroxy propyl distarch phosphate solution into the emulsion, stirring, standing, centrifuging at the temperature of 25 DEG C and at a rotation speed of 10000rpm, drying at the room temperature and the negative pressure to obtain the prinsepia utilis royle fruit oil microsphere, wherein the coating is gelatin. The preparation method is mild in conditions, free of organic solvent and low in ionic concentration.

Description

technical field [0001] The invention relates to the technical field of food oil, in particular to an oil microsphere and a preparation method thereof. Background technique [0002] Green thorns belong to the genus Rosaceae and grow on hillsides or streams at an altitude of 1000-3000 meters. The green thorn fruit oil made from the green thorn nuts is rich in a variety of essential fatty acids, fat-soluble vitamins A, D, E, K and various trace elements, and the unsaturated fatty acid content is over 70%. And the ratio of oleic acid to linoleic acid is close to 1:1, which meets the nutritional needs of the human body. In addition, according to research, the green thorn fruit oil has antibacterial effects, hypoxia resistance, anti-brain hypoxia effects, blood lipid regulation, and in vitro inhibition of platelet aggregation, etc., and has therapeutic effects on various diseases of the human body. Green thorn fruit oil is widely used in the fields of food, cosmetics and health ...
