Abstract

The invention discloses a cryopreservation method for persimmons. The cryopreservation method comprises the specific steps that (1) the harvested persimmons are fumigated through 0.5-1.0 [mu]l / L of methylcyclopropene for 4-6 hours; (2) the fumigated persimmons are placed in purified water to be soaked for 5-10 min; (3) the surfaces of the persimmons are blown dry; (4) oil wax containing a cryopreservation agent is sprayed on the persimmons; (5) the surfaces of the persimmons are dried; and (6) the dried persimmons are stored in a cold storage with the temperature being 4 DEG C and the relativehumidity being 70-80%. By adopting the cryopreservation method for the persimmons, the reliable and effective effects are achieved, pollution is avoided, and the side effect is small.

Description

technical field [0001] The invention relates to a low-temperature preservation method, in particular to a low-temperature preservation method for persimmons. Background technique [0002] Persimmon is sweet and astringent, cold in nature and non-toxic; persimmon is astringent in taste and flat in nature, and enters the lung, spleen, stomach, and large intestine meridians; Hemostasis and other functions can relieve dry stool, hemorrhoid pain or bleeding, dry cough, sore throat, high blood pressure and other symptoms. Therefore, persimmon is a natural health food for patients with chronic bronchitis, hypertension, arteriosclerosis, and internal and external hemorrhoids. If persimmon leaves are decocted or boiled as tea, it can also promote the body's metabolism, lower blood pressure, increase coronary blood flow, and relieve cough and reduce phlegm. It can tonify deficiency, relieve cough, benefit intestines, remove heat, stop bleeding, and satisfy hunger. [0003] The path...
