Abstract

The invention discloses a color fixing and freshness keeping agent for bamboo shoots and a color fixing and freshness keeping method for the bamboo shoots. The color fixing and freshness keeping agent is prepared from ascorbic acid or iso-ascorbyl sodium, ethylenediamine tetraacetic acid disodium, L-cysteine or L-cysteine hydrochloride, sodium phytate, epsilon-polylysine or epsilon-polylysine hydrochloride and sodium citrate. The color fixing and freshness keeping method includes: preparing raw material bamboo shoots, soaking for desulfurization and preservation, adding color fixing and freshness keeping liquor, filling, sterilizing and the like. Due to fact that a stable chlorine dioxide solution with rotting prevention and color fixing characteristics is combined with the safe and effective color fixing and freshness keeping agent and key process control is used, browning and rotting of the bamboo shoots are inhibited, standard exceeding of chlorine dioxide is prevented, and safety of the bamboo shoots is improved.
