Abstract

The invention discloses a method for microencapsulating pitaya peel pigment. The method comprises the following steps: A, dissolving a core material (namely pitaya peel pigment) into water, with that, obtaining a core material solution for standby, wherein the concentration of the core material solution is 95-98 percent; B, preparing a wall material, taking and mixing the wall material, and adding cellulose acetate phthalate into the wall material, with that, obtaining a wall material solution for standby; C, mixing the core material solution, the wall material solution, the water and an emulsifier, performing high-pressure homogenization to obtain emulsion, wherein the solid content of the emulsion is 15-30 percent; performing spray drying to the emulsion to obtain the microencapsulated pitaya peel pigment. According to the invention, via microencapsulating the pitaya peel pigment, the stability of the pitaya peel pigment and the solubility of the pitaya peel pigment in a fat-soluble medium are improved, and the technical effect of the food industry application of the pitaya peel pigment is expanded.

Description

technical field [0001] The invention relates to a method for processing pitaya peel pigment, in particular to a method for microencapsulating the pitaya peel pigment. Background technique [0002] Pitaya peel pigment is a water-soluble natural red pigment, soluble in ethanol, acetone, isopropanol, acetic acid, citric acid, tartaric acid and 0.2mol / L HCl solution, slightly soluble in ether and ethyl acetate, the Pigment has the characteristics of polar or weak polar molecular substances, and is a kind of polar or weak polar molecular substances. [0003] Pitaya peel pigment is easy to absorb, has strong biological activity, has biological activities such as anti-oxidation, cardiovascular protection, and anti-mutation, and is widely used in food, medicine, cosmetics and other fields. In recent years, pitaya peel pigment has become a commonly used raw material in health food in my country. However, since the pitaya peel pigment is easily affected by external conditions, such ...
