Preparation method for astaxanthin microcapsules

Abstract

The invention belongs to the technical field of biological products, and relates to a preparation method for astaxanthin microcapsules. The specific process is as follows: uniformly stirring pure gum, maltodextrin and distilled water to prepare wall material solution at first, and then mixing and stirring the wall material solution with a compound emulsifier until the wall material solution is completely emulsified to obtain wall material emulsifier solution; then carrying out a wall-breaking treatment on haematococcus pluvialis spores and then preparing astaxanthin solution by a conventional extraction process, and mixing the astaxanthin solution with vitamin E to obtain astaxanthin oil solution; then mixing and stirring the wall material emulsifier solution with the astaxanthin oil solution until an emulsifier is formed, then homogenizing by a super cell homogenizer, adjusting the temperature of the emulsifier, and then homogenizing by the super cell homogenizer until water-colour oil microcapsules are formed; finally carrying out spray-drying on the water-colour oil microcapsules by a spray dryer until a wall material is condensed, so as to prepare the astaxanthin microcapsules. The preparation method is simple in process, high in product activity, good in application effect, stable in performance, free from the influence of external environment, and high in utilization rate.

Description

Technical field:

[0001] The invention belongs to the technical field of biological product preparation, and relates to a method for preparing astaxanthin microcapsules, which can replace the astaxanthin products in the prior art and be used in the technical fields of medical care and sanitation and epidemic prevention. Background technique:

[0002] Astaxanthin is a high-efficiency pure natural antioxidant, a kind of carotenoid, which is a fat-soluble and water-soluble natural pigment, which can be extracted from marine organisms such as shrimp, crab, salmon and algae; natural astaxanthin Carotene has strong antioxidant capacity, which is 550 times that of vitamin E and 10 times that of β-carotene. Its main function is to scavenge free radicals, improve the body's anti-aging ability, protect skin and eyes, resist radiation, and prevent cardiovascular disease. effects on aging, dementia and cancer. At present, astaxanthin is generally made into microcapsule solid particles b...
