The invention relates to the technical field of
processing of
bamboo shoots, and discloses a preservation
processing method of the
bamboo shoots. The method comprises the following steps: (1) positioning freshly-picked
bamboo shoots into a foam heat insulation box in which ice cubes are arranged; spraying a layer of anti-oxidant
antibacterial agent; then
coating the bamboo shoots with shells through natural
plant extracts, and then performing
cold storage, wherein the
breathing of cells of the bamboo shoots is inhibited through the synergistic effect, and meanwhile, the
ageing speed of the bamboo shoots can be slowed down, so that the crisp and tender sensory attributes of the bamboo shoots can be maintained; (2)
slicing the bamboo shoots which are subjected to
cold storage, and then soaking the slices into a nutritional preservation solution to provide nutrients to the bamboo shoots, wherein the material basis is provided for the
metabolism of the bamboo shoots, and the
ageing and water loss of the bamboo shoots are delayed, thus the fresh taste of the bamboo shoots is maintained; moreover, the lignification rate can be decreased, the
cellulose accumulation is reduced, and thus the bamboo shoots can be kept in a crispy and tender state; (3) treating the sliced bamboo shoots by means of
microwave and intensive
pulse light, wherein the activity of
enzyme in the sliced bamboo shoots is damaged to cause long-term
passivation, thus the comprehensive sterilizing effect is achieved, and as a result, the
expiration date and the
shelf life of the bamboo shoots are prolonged.
