Take the scale as raw material, cuts, the low temperature purification, freeze-drying after the directional enzyme becomes, the molecular weight 92% concentrates in 1000Dal, has the extremely high biological activity, widely applies in domains and so on food, cosmetics and healthy product.

Fish scale as raw materials, refined by directed enzyme and low temperatures, freeze drying and the molecular weight is 92% focused on 1000Dal, it has a high biological activity, widely used in areas such as food, cosmetics and health products.
