This disclosure is concerned with the demineralization of crustacea shells and the like, before or after protein removal therefrom, with sulfurous acid, thus to convert the calcium carbonate of the shell to calcium bisulfite solution which may be separated from the solid residual shell, and regenerating sulfurous acid from the said solution for reuse in the process.
本公开涉及使用亚硫酸对甲壳类壳及类似物进行脱矿化处理的方法,无论是在蛋白质去除前还是后进行处理。这样可以将壳中的碳酸钙转化为亚硫酸钙溶液,从而可以将固体残留壳与其分离。同时,还可以从该溶液中再生亚硫酸,以便在处理过程中再次使用。
