Abstract

The invention provides a preparation method of quick-frozen bamboo shoots. The method includes the steps of: cleaning selected fresh bamboo shoots with clear water, and then drying the moisture on surfaces of the cleaned bamboo shoots; soaking the fresh bamboo shoots in tincture of iodine with a concentration of 3.2% for 30min, and then further performing soaking with a sodium chloride aqueous solution for 20min; brushing a layer of chlorophyll on the surfaces of the bamboo shoots, and then performing freezing to -10DEG C; taking out the bamboo shoots, and performing thawing to 5-10DEG C, and then using a fresh-keeping liquid to perform soaking treatment for 1h; then flushing the bamboo shoots with room temperature distilled water once, then performing natural air drying till no water dripping on the surface, then putting the bamboo shoots into a instant freezer and conducting quick-freezing to -15DEG C, then detecting the bamboo shoots, performing packaging when the bamboo shoots are qualified, and storing the finished product in a -20DEG C cold storage. The method provided by the invention employs tincture of iodine to soak bamboo shoots, ensures no water loss of bamboo shoots, and the treated bamboo shoots have no nutrient loss and enough crispness, thawed bamboo shoots do not soften, and bamboo shoot fiber has enough elasticity.
