Embodiment 1

[0019] A freeze-drying and fresh-keeping processing technology of cistanche, characterized in that it comprises the following steps:

[0020] (1) Harvesting and grading: the large Cistanche cistanche excavated is cleaned to remove sand and soil, and is classified according to the grading standard;

[0021] (2) Slicing: slice the washed Cistanche transversely, the thickness of the slice is about 15mm, and put it into the original shape after slicing, and connect it with two threads, which is beneficial to restore the original shape;

[0022] (3) Enzyme elimination and sterilization: putting the sliced ​​Cistanche deserticola into a sugar solution with a temperature of 90° C. and a sugar content of 50% for enzyme elimination and sterilization;

[0023] (4) Arrangement: place the Cistanche cistanche slices that have been sterilized and sterilized at 9 kilograms per square meter in a freezer tray;

[0024] (5) Ultra-low temperature quick-freezing: put the Cistanche cistanche slic...

Embodiment 2

[0028] A freeze-drying and fresh-keeping processing technology of cistanche, characterized in that it comprises the following steps:

[0029] (1) Harvesting and grading: the small Cistanche cistanche excavated is cleaned to remove sand and soil, and is classified according to the grading standard;

[0030] (2) Enzyme elimination and sterilization: putting the sliced ​​Cistanche deserticola into a honey solution with a temperature of 70° C. and a sugar content of 50% for enzyme elimination and sterilization;

[0031] (3) Arranging the plate: put the Cistanche cistanche slices that have been sterilized and sterilized at 8 kg per square meter in a freezer plate;

[0032] (4) Ultra-low temperature quick-freezing: put the cistanche slices frozen plate after the enzyme-killing and sterilized treatment into the quick-freezing box, and turn on the freezer after airtight, so that the cistanche slices in the quick-freezing box are frozen at a temperature of -80°C for 6 hours;

Abstract

The invention relates to a processing technology of freeze drying and fresh-keeping of cistanche, and relates to the cistanche preservation technical field. The processing technology comprises the following steps: collecting and grading, slicing, killing enzyme and disinfecting, loading in a tray, quickly freezing at ultralow temperature, performing vacuum dehydrated drying, and sealing and packaging. The defect of cistanche nutrition loss caused by current cistanche drying and fresh-keeping technology in the prior art can be effectively overcome. The invention is characterized in that the cistanche contains a heat sensitivity substance, denaturation or inactivation performance can not be generated, the volatile component loss in cistanche is little; cistanche can keep original property and structure, the dried cistanche is loosened and porous, and presents a sponginess state, the original property can be recovered after 2-4 hours by adding water, the volume is almost unchanged; the good original state can be kept after slicing the cistanche, and the sliced cistanche can be connected through several lines, which is in favor of original state recovery, the substance capable of easily being oxidized in cistanche can be protected, more than 95-99% of moisture can be eliminated after drying, so that long-term fresh keeping of the dried produce can be realized.

Description

technical field [0001] The invention relates to the technical field of Cistanche preservation, in particular to a freeze-drying and fresh-keeping processing technology of Cistanche. Background technique [0002] Cistanche deserticola is a parasitic plant that lives on the roots of desert trees Haloxylon and tamarisk. It is known as "desert ginseng" and has extremely high medicinal value. It is a traditional Chinese medicinal material in my country. Metabolism and strengthening effects, enhancing immunity (can significantly increase the weight of spleen and thymus), lowering blood pressure, anti-atherosclerosis, etc. It has a significant effect on kidney yang deficiency, loss of essence and blood, impotence, nocturnal emission, cold pain in the waist and knees, tinnitus and blurred vision, turbidity, frequent urination, irregular menstruation, metrorrhagia, infertility, intestinal dryness and constipation. It is also the highest-grade medicine among more than 60 kinds of toni...
