Problems solved by technology

This method has the following disadvantages: a large amount of rubber powder is used in this method, so it is easy to cause excessive viscosity, or require a large amount of water to dissolve, resulting in high energy consumption of spray drying, and the stirring time of the whole process is too long; two-phase The particle size produced by mixing and stirring is too large, it is difficult to ensure the uniformity of the emulsion, thus affecting the embedding effect

Embodiment 1

[0025] Capsanthin microcapsules with a color value of 150 were used as raw materials to prepare capsanthin microcapsules.

[0026] Add 1 g of vitamin E to 10 g of capsanthin, heat to 30° C. and stir for 10 minutes until the vitamin E dissolves, thereby obtaining a core material phase. Add 60g of modified starch into 100mL of water, heat to 50°C and stir for 30 minutes to dissolve the modified starch, then add 27g of dextrin and 2g of phospholipid, continue stirring for 30 minutes until the dextrin and phospholipid are dissolved, and cool to 20°C to obtain Capsule phase. The core material phase and the capsule material phase were mixed, and emulsified and homogenized by a high-pressure homogenizer at 20 MPa to obtain an emulsion with a particle size of 1000 nm. Under the conditions of 160°C inlet air temperature and 70°C outlet air temperature, the emulsion is dried in a spray drying tower to prepare capsanthin microcapsule powder.

Abstract

The invention discloses a method for preparing a capsanthin microcapsule, comprising the following steps of: (1) preparing capsanthin core phase; (2) preparing modified starch capsule phase; (3) mixing the capsanthin core phase and the modified starch capsule phase and emulsifying and homogenizing the mixture into emulsified liquid with a nanometer grain diameter at high pressure; and (4) drying the emulsified liquid to obtain the capsanthin microcapsule. The method for preparing the capsanthin microcapsule microencapsulates capsanthin by adopting microencapsulation technology and coats the capsanthin (core) into the microcapsule with a nanometer grain diameter by using single capsule modified starch. The method for preparing the capsanthin microcapsule has simple process, and the prepared product has good water solubility and high stability.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a method for preparing capsanthin microcapsules. Background technique [0002] Capsanthin is a dark red oily viscous liquid extracted from peppers. It is a natural pigment whose main components are red pigments such as capsanthin and capsanthin, and yellow pigments such as capsanthin, zeaxanthin and cryptoxanthin. Capsanthin is easily soluble in acetone, n-hexane, chloroform and other organic solvents and vegetable oils, insoluble in water, and very sensitive to light and oxygen, so it is very unstable. [0003] Capsanthin has bright color, strong coloring power, non-toxic and no side effects, so it is widely used in food, medicine and cosmetics. In addition, it is also used in advanced feed, aquatic products and other fields, so it has great development value. However, due to its poor stability, it is an oil-soluble pigment, and it is usually made into a water-dispersible pigmen...
