A kind of preparation method of using ultra-high pressure to keep fresh fragrant bamboo shoots

Abstract

The invention discloses a preparation method for retaining the freshness of fragrant bamboo shoots at a super-high pressure. According to the technical scheme of the invention, fresh fragrant bamboo shoots are cleaned by an automatic spray cleaning machine, and then the fresh fragrant bamboo shoots are subjected to anti-oxidation treatment by an automatically cyclic spraying type low-temperature anti-oxidation processor. After that, the bamboo shoots are subjected to heat treatment by a microwave heating type food drying machine and then are packaged by a full-automatic type continuous-drawing vacuum packaging machine. The packaged bamboo shoots are subjected to super-high pressure treatment by a super-high pressure bamboo shoot processor and then are subjected to quality inspection. Finally, the bamboo shoots are packaged as bamboo shoot products, so that super-high-pressure freshness-retaining type fragrant bamboo shoots are obtained. In this way, the freshness-retaining effect of fragrant bamboo shoots is realized through the super-high-pressure treatment, so that the quality of fragrant bamboo shoots within the shelf life is improved. Meanwhile, fragrant bamboo shoots are good in color, brittleness and freshness.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of fresh-keeping fragrant bamboo shoots using ultra-high pressure. Background technique [0002] Fragrant bamboo shoots are the young shoots of bamboo, also known as bamboo shoots.
