Product Description
Product Description
Astaxanthin is a type of carotenoid with extremely strong antioxidant properties, being 100 times more effective than vitamin E. In feed, it is mainly used in fish feed and can be used as a colorant. It also has excellent biological functions.

Product production process introduction:
At present, the production methods of carotenoids mostly adopt chemical synthesis or extraction from natural products. Although the chemical method has a low production cost, its biggest drawback is the low biological activity, which reduces the efficacy of the products. The carotenoids extracted from natural products have extremely high biological activity, but the production cost is too high.
Our company's production process selects the biological fermentation method. By using modern biotechnology to revolutionize the product process, we replace the synthesis method with the biological method to produce carotenoids. The products produced by the biological method have biological activity and can be comparable to natural products, but the production cost is much lower than the natural extraction process. It can reduce costs, improve product quality, be environmentally friendly, and reduce pollution.
