Embodiment 1

[0019] A dry processing method of cistanche, carried out according to the following steps:

[0020] (1) selection: select the complete fleshy stem of Cistanche tubulosa without damage by diseases and insect pests, its length > 15cm;

[0021] (2) cleaning: clean the surface silt with water for the selected Cistanche cistanche;

[0022] (3) Slicing: the cleaned Cistanche cistanche meaty stem is horizontally cut into uniform slices, and its thickness is 2mm;

[0023] (4) Blanching to kill enzymes: Place Cistanche cistanche slices in a single layer on a material tray, and use high-temperature, high-humidity superheated steam to perform anhydrous blanching, sterilization and enzyme-killing treatment. The blanching temperature is 110°C; superheated steam is relatively Humidity 35%; superheated steam speed 9m / s; blanching time 60s;

[0024] (5) Gas jet impingement drying: Put the slices of Cistanche cistanche after blanching and enzyme treatment into a gas jet impingement drying ov...

Embodiment 2

[0027] A dry processing method of cistanche, carried out according to the following steps:

[0028] (1) selection: select the complete desert Cistanche succulent stem without damage by diseases and insect pests, its length > 15cm;

[0029] (2) cleaning: clean the surface silt with water for the selected Cistanche cistanche;

[0030] (3) Slicing: the cleaned Cistanche cistanche meaty stem is horizontally cut into uniform slices, and its thickness is 4mm;

[0031] (4) Blanching to kill enzymes: Place Cistanche cistanche slices in a single layer on the material tray, and use high-temperature, high-humidity superheated steam to perform anhydrous blanching, sterilization and enzyme-killing treatment, and the blanching temperature is 120°C; superheated steam is relatively Humidity 35%; superheated steam velocity 12m / s; blanching time 90s;

[0032] (5) Gas jet impingement drying: Put the slices of Cistanche cistanche after the enzyme treatment of blanching into a gas jet impingemen...

Embodiment 3

[0035] A dry processing method of cistanche, carried out according to the following steps:

[0036] (1) selection: select the complete fleshy stem of Cistanche saline without damage by diseases and insect pests, its length > 15cm;

[0037] (2) cleaning: clean the surface silt with water for the selected Cistanche cistanche;

[0038] (3) Slicing: the cleaned Cistanche cistanche meaty stem is horizontally cut into uniform slices, and its thickness is 4mm;

[0039] (4) Blanching to kill enzymes: Place Cistanche cistanche slices in a single layer on the material tray, and use high-temperature, high-humidity superheated steam to perform anhydrous blanching, sterilization and enzyme-killing treatment, and the blanching temperature is 120°C; superheated steam is relatively Humidity 40%; superheated steam speed 12m / s; blanching time 90s;

[0040] (5) Gas jet impingement drying: put the slices of Cistanche cistanche after the enzyme treatment of blanching into a gas jet impingement d...

Abstract

The invention discloses a dry processing method for cistanche deserticola, which belongs to the technical field of agricultural product processing. The method comprises choosing fresh cistanche deserticola fleshy stem, cleaning up, slicing, blanching at high temperature of 100 DEG C to 120 DEG C to extinguish enzyme and sterilize for 60 seconds to 120 seconds, drying through air flow impact at the temperature of 50 DEG C to 80 DEG C for 5 hours to 10 hours, cooling after being dried, and finally packing to obtain. The method uses blanching, enzyme extinguishing and sterilizing processing, thereby effectively restraining activity of enzyme and microorganisms, reducing mildew of fresh cistanche deserticola and loss in drying processes, preventing color and luster of the cistanche deserticola and improving quality of products. Air injection flow impact drying technology is utilized, so that drying speed of cistanche deserticola is effectively improved, drying time is shortened, and energy consumption in drying processes is saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for drying and processing Cistanche deserticola. Background technique [0002] Cistanche tubulosa (Schenk) R.Wight is a perennial obligate root parasitic plant of Orobanchaceae (Orobanchaceae) Cistanche Hoffing.et Link. Efficacy, it is the most frequently used traditional Chinese medicine for invigorating the kidney, known as "desert ginseng". [0003] Cistanche has high sugar content and slow water loss. It usually takes 2-4 months to dry naturally, which is slow to dry and easy to mold. Studies have shown that during the natural drying process of Cistanche, due to the action of hydrolase and polyphenol oxidase, enzymolysis and enzymatic browning are very prone to occur, which will not only reduce the effective medicinal ingredients of Cistanche, but also make the dried The dark color of Cistanche has seriously affected the sensory ...
