ABSTRACT:
The inventor has found that enzymatic treatment of crustaceans with lipolytic enzymes promotes the extraction of coloured pigment. Accordingly, the invention relates to a method for recovering coloured pigment, e.g. astaxanthin, and/or chitin or chitosan and/or lysolecithins from crustaceans. Lipolytic enzyme(s) may e.g. be lipase or phospholipase. The lipolytic enzyme treated crustacean material may be subjected to additional process steps, including treatment with non-lipolytic enzymes such as e.g. protease. The process of the invention provides several suitable products and several uses of such products. Furthermore, the invention also relates to the cosmetic and consumable products (feed and food (including beverages) products and additives produced therefrom.
