Embodiment 1

[0020] A processing method of sulfur-free pinellia, the steps are:

[0021] A. Select the fresh pinellia, select out the impurities that cannot be used as medicine and the pinellia that has deteriorated and become invalid, and then classify the selected pinellia according to the size, clean the pinellia according to the gear, and use the pinellia Peeling machine for peeling.

[0022] B. Immerse the peeled pinellia of the same grade in a color-protecting agent for color protection. The color-protecting agent contains 0.2% ascorbic acid, 0.2% citric acid, and 0.05% L-cysteine A mixed solution of amino acid, 0.2% sodium chloride and 0.2% calcium chloride, wherein the mass ratio of the color-protecting agent to Pinellia is 1:5, and after color-protecting for 1 hour, the Pinellia after color-protecting is washed with water Clean and air dry until the moisture attached to the surface of pinellia evaporates.

[0023] C. Put the pinellia that has been treated with color protection a...

Abstract

The present invention discloses a sulfur-free pinellia ternata processing method. According to the method, fresh pinellia ternata is subjected to selection and grading, the fresh pinellia ternata having the same grade is peeled, and the peeled pinellia ternata is subjected to color protection treatment by using a special color protection agent, wherein the special color protection agent comprises any three, four or five materials selected from ascorbic acid with a mass percent concentration of 0.04-0.4%, citric acid with a mass percent concentration of 0.1-0.6%, L-cysteine with a mass percent concentration of 0.01-0.06%, sodium chloride with a mass percent concentration of 0.1-0.6%, and calcium chloride with a mass percent concentration of 0.1-0.4%; after the color protection treatment is completed, the obtained pinellia ternata is conveyed into drying equipment, and drying is performed until the water content in the pinellia ternata is less than 15%, wherein high temperature enzyme inactivation and bacterial killing are performed before the drying; and the dried pinellia ternata is cooled to a room temperature, and the cooled pinellia ternata can be directly subjected to vacuum sealed packaging or can be stored at a safe temperature and a safe humidity. According to the present invention, the method has characteristics of simple process and easy operation, the obtained pinellia ternata finished product has characteristics of white surface, good color and no sulfur residue, and the chemical components and the medicinal value of the pinellia ternata are not affected, and the advantages of economy and environmental protection are provided.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, and relates to a processing method of pinellia, in particular to a processing method of sulfur-free pinellia. Background technique [0002] Pinellia is the dry tuber of Pinellia araceae. It has the effects of drying dampness and resolving phlegm, reducing adverse reactions and relieving vomiting, and dissipating mass. Swollen phlegm nucleus and other diseases are traditional Chinese medicinal materials. [0003] Fresh pinellia is perishable and needs to be dried after harvesting to facilitate preservation. The skin of pinellia is not of much use value. Fresh pinellia needs to be peeled during the processing process. The surface of fresh pinellia is white and bright after peeling, but the surface color turns yellow after drying, which seriously affects its appearance quality and price. In order to improve the appearance of pinellia products, sulfur fumigation is often used ...
