概要
Astaxanthin Microencapsulated Powder, also known as Astaxanthin Microcapsule Powder, refers to a powdered product made by encapsulating natural astaxanthin as the core material within food-grade wall materials (such as sodium starch octenylsuccinate, maltodextrin, gum arabic, etc.) using microencapsulation technology. Astaxanthin is a carotenoid with the chemical formula C40H52O4, molecular weight of 596.90 g/mol, and CAS number 472–61–7.Astaxanthin is widely found in Haematococcus pluvialis, Phaffia yeast, krill, and other organisms, and is one of the strongest natural antioxidants in nature. The antioxidant capacity of natural astaxanthin is approximately 550–1000 times that of vitamin E. The core value of Astaxanthin Microencapsulated Powder lies in its ability to solve the application bottlenecks of natural astaxanthin—poor water solubility, low stability, and low bioavailability—through microencapsulation technology. Microencapsulated astaxanthin improves its water solubility and stability, making its stability and efficacy far superior to ordinary astaxanthin powder. Astaxanthin Microencapsulated Powder is mainly divided into natural astaxanthin microencapsulated powder (derived from Haematococcus pluvialis extract) and synthetic astaxanthin microencapsulated powder (derived from chemically synthesized astaxanthin).Natural astaxanthin microencapsulated powder is rich in 100% L-isomer (all-trans) astaxanthin with the strongest biological activity.
Astaxanthin Microencapsulated Powder possesses multiple unique performance advantages:
Astaxanthin is the strongest antioxidant discovered in nature for inhibiting free radical absorption in the human body. Its biological antioxidant capacity is 100–500 times stronger than vitamin E and more than 10 times stronger than carotene. Astaxanthin Microencapsulated Powder inherits the super antioxidant activity of astaxanthin, capable of capturing and eliminating free radicals in the body, reducing oxidative stress damage to cells.
