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.
