Processing method of fresh dried cistanche deserticola slices and product obtained by processing method

Abstract

The invention provides a processing method of fresh dried cistanche deserticola slices, and belongs to the technical field of processing of traditional Chinese medicinal materials and agricultural products. The method comprises the following steps: cutting cistanche deserticola into slices until the thickness of cistanche deserticola slices is 0.1-0.3 cm to obtain cistanche deserticola slices; then drying the cistanche deserticola slices at the temperature of 50-60 DEG C under the microwave condition of minus 10-minus 6Pa for 15-20 minutes to obtain primary dried slices; and finally, drying the primary dried slices in an air circulation drying environment until the water content of materials is 1-5% to obtain the fresh dried cistanche deserticola slices. According to the method provided by the invention, a vacuum low-temperature microwave drying technology is adopted, so that polysaccharide of a cistanche deserticola dried product is not oxidized in a vacuum environment, cells are loose and shrink-resistant, and effective components of the cistanche deserticola can be reserved to the greatest extent; oxygen-free operation is achieved in the whole processing process, air pollution and cistanche deserticola polysaccharide oxidation can be avoided, the polysaccharide content is high, and the taste is sweet and mellow; and the fresh dried cistanche deserticola slices are sealed in vacuum, are preferably packaged into independent small packages of 2g, are ready-to-eat after being opened, and are convenient, quick, safe and healthy.

Description

technical field [0001] The invention relates to the technical field of processing traditional Chinese medicinal materials and agricultural products, in particular to a processing method of fresh and dried Cistanche deserticola slices and a product thereof. Background technique [0002] Cistanche deserticola is a perennial parasitic herb, which mainly parasitizes the roots of psammophytes Haloxylon. Cistanche deserticola is used as medicine with scaly fleshy stems. The main components are verbascoside and echinacoside, which are phenylethanol glycoside compounds. Function, memory dysfunction, prevent Alzheimer's disease, promote the growth and repair of nerve cells, anti-atherosclerosis and other pharmacological effects. [0003] Cistanche deserticola is rich in polysaccharides, with a water content of more than 80%, of which 70% of the water exists in the intercellular space, and 30% of the water exists in the polysaccharides in the cells. Drying at room temperature can on...

AI Technical Summary

Problems solved by technology

Normal temperature drying method can only remove intercellular moisture, but it is difficult to remove intracellular moisture

The high-temperature drying method will cause serious shrinkage of the cells while removing the water in the cells, and at the same time cause the polysaccharides in the cells of Cistanche to be oxidized, resulting in the dried Cistanche being black and hard, with the loss of active ingredients and difficult processing
