DEPROTEINIZATION OF CARAPACE OF CRUSTACEA

摘要

PURPOSE: To safely remove about ≥95wt.% protein contained in a carapace of a Crustacea by adding a specified amount of a fatty acid sodium salt to the carapace. ;CONSTITUTION: About 95wt.% protein based on the whole protein contained in a carapace of a Crustacea is removed by adding about ≥1wt.% fatty acid sodium salt (e.g. detergent sold on the market), preferably a mixture of ≥1wt.% fatty acid sodium salt and 0.1wt.% sodium carbonate to the carapace. Since chitin, chitosan and their calcium salts obtained by this invention exist each in a bonded state, the above-mentioned substances exhibit the same effect as in a brine when used for processing Chinese noodle, etc.;COPYRIGHT: (C)1993,JPO&Japio
