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...

AI Technical Summary

Problems solved by technology

At present, astaxanthin is generally made into microcapsule solid particles before use, and then processed into tablets, soft capsules or pills. Due to the high activity of astaxanthin, its performance is unstable and it is easily affected by the external environment, especially light and Loss of activity under the influence of heat; Chinese patent 201210561599.7 discloses a preparation process of astaxanthin microcapsules, the wall material is mixed with water to form a wall material solution, and then an emulsifier with a concentration of 6% by weight is added to make a wall material emulsifier solution , then add astaxanthin oil solution with a mass percent concentration of 3%, stir vigorously to form an astaxanthin emulsifier, then disperse and stir at 30000r / min for 1min, disperse and stir at 30000r / min for 1min three times, and finally carry out spray drying to prepare Astaxanthin capsules, but its process and product stability are poor, easily affected by the external environment and lose activity, and the utilization rate is low. Therefore, it is very difficult to develop a new process for the preparation of astaxanthin microcapsules with stable performance and not affected by the external environment. Has application prospects and social value
