い方法とは云えない。2. Description of the Related Art Conventionally, various methods have been proposed for deproteinizing shells of crustaceans to produce chitin, chitosan, and calcium salts. However, the use of sodium hydroxide for deproteinizing these proteins removes proteins. Although it is an effective method in that respect, sodium hydroxide itself is not a preferable method because it requires a considerable investment from a storage facility to a treatment facility because it has a danger as a chemical substance.

効果を表１に示す。The present inventors have conducted various studies on substances that can be deproteinized in place of sodium hydroxide. When at least 1% by weight of sodium fatty acid and a small amount of sodium carbonate (0.05% by weight) are used together. We obtained the finding that the deproteinization effect is great. The present inventors have completed the present invention as a result of further research based on these findings. Table 1 shows the shrimp shell protein removal effect by the surfactant drug substance, which is the result of the present inventors' studies.
