The invention discloses a production method of an
alcohol-based
ginkgo leaf sterilization and preservation solution. The technical scheme of the production method comprises the following steps: mixing a crushed
ginkgo leaf mixture with edible
alcohol, and then adding the obtained mixture into a stainless steel container for soaking; performing filter pressing; blending; and
dewatering and filling to finally obtain the finished product of the
alcohol-based
ginkgo leaf sterilization and preservation solution. The alcohol-based ginkgo leaf sterilization and preservation solution is prepared from ginkgo leaf,
mulberry leaf,
lotus leaf, cacumen platycladi, tree peony leaf, tree peony
bark, pomegranate rind, Chinese redbud
bark and alcohol. The alcohol-based ginkgo leaf sterilization and preservation solution has the beneficial effects that the effective ingredients of the alcohol-based ginkgo leaf sterilization and preservation solution are slowly released and permeated into the whole space in food
package so as to form a layer of sterilization and preservation film on the surface of food; and after the alcohol-based ginkgo leaf sterilization and preservation solution is contacted with the food with
high water content, the alcohol concentration of the sterilization and preservation film is not less than 70 degrees so that the optimum bactericidal concentration can be maintained for a longer time, thus achieving the purposes of sterilizing and refreshing the food in the whole
shelf life. Therefore, the alcohol-based ginkgo leaf sterilization and preservation solution is efficient and applicable to sterilizing and refreshing fruit, vegetable and other food.
