Embodiment

[0024] Embodiment: select the Houttuynia cordata rhizome with whiter color, no disease spots, no insect population, and uniform thickness, wash and drain, and cut into 10cm sections, and use 0.7% sodium pyrosulfite, 0.1% citric acid and 0.1 % Vitamin C mixture soaked for 70 minutes, drained and then soaked in 0.5% calcium chloride solution for 20 minutes, drained, continued to soak in 2.5% potassium sorbate solution for 10 minutes, drained, and then packed fish according to the 250g of Houttuynia cordata and 90mL of fresh-keeping solution are vacuum-packed, and the packaged Houttuynia cordata is boiled in hot water at 70°C for 2 minutes to complete the fresh-keeping treatment. The Houttuynia cordata treated in this way does not deteriorate during storage at a temperature of 25° C. for 4 months.

[0025] The houttuynia cordata fresh-keeping liquid is formulated by mixing equal amounts of color-protecting liquid, crisp-preserving liquid and preservative liquid, wherein the color...

Abstract

The invention discloses processing technology for preserving cordate houttuynia, and preservation solution. The processing technology comprises the following steps of: selecting and cleaning the cordate houttuynia, conserving the color of the cordate houttuynia, keeping crisp of the cordate houttuynia, performing corrosion protection on the cordate houttuynia, packing the cordate houttuynia in vacuum, sterilizing the cordate houttuynia, storing the cordate houttuynia and other procedures, wherein soaking the rhizome of the cleaned cordate houttuynia in mixed solution of 0.7 percent of sodium pyrosulfite, 0.1 percent of citric acid and 0.1 percent of vitamin C, 0.5 percent of calcium chloride and 2.5 percent of potassium sorbate, filling the soaked rhizome of the cleaned cordate houttuynia in a vacuum pack filled with preservation solution, and sterilizing. Based on multiple kinds of preserving treatment, the processing technology maintains the intrinsic quality of the cordate houttuynia, can prolong the supply period of the cordate houttuynia, lessens corrosion and brown stains of the cordate houttuynia, maintains the unique flavour of the cordate houttuynia through the processes of preventing brown stains, preventing corrosion and preserving freshness, keeping crisp, packing in vacuum and the like, solves the problems of brown stains and corrosion in the storage period of the cordate houttuynia when used for storing and preserving the cordate houttuynia, and keeps the crisp during the storage period of the cordate houttuynia.

Description
