Method for prevention of quality changes and cyanide ion formation of the bamboo shoots using calcium salts

摘要

The present invention relates to a method for suppressing tissue softening and cyanide formation of bamboo shoots using calcium chloride. According to the present invention, hydrogen cyanide, which is a natural toxic substance of bamboo shoots, is chlorinated through ionic decomposition with an alkaline calcium salt (CaCl_2) which does not have off-flavor and malodor among food additives in the form of calcium salt containing divalent calcium ions and is decomposed to harmless Na_2CO_3, N_2, NaCl, H_2O. By suppressing the quality change of bamboo shoots and effectively suppressing the formation of cyanide, which is a toxic substance of bamboo shoots, compare to a salting method as a conventional bamboo shoot storage method, the present invention contributes to an increase in a quality maintenance period of other processed products and development of the processed products using bamboo shoots. Therefore, it is possible to secure a unique effect of diversifying processed bamboo shoot products and increasing the usability of bamboo shoots.
