Technical Field

The invention belongs to the technical field of polygonatum sibiricum soft sweet processing, and particularly relates to a simple production place processing method of polygonatum sibiricum soft sweet.

Background

Huang Jing was recorded in the miscellaneous records of famous physicians, and is the top-grade medicine, "taking lightly and prolonging life without hunger for a long time", and has the effects of tonifying qi and yin, invigorating spleen and tonifying kidney. It is often used for dry cough due to lung deficiency, qi deficiency of spleen and stomach, inappetence, deficiency of kidney essence, soreness and weakness of waist, early white hair, and hyperglycemia. Rhizoma polygonati is capable of tonifying qi and nourishing yin, and is suitable for being eaten in autumn and winter. Rhizoma Polygonati is suitable for treating hyperglycemia, diabetes, hyperlipemia (especially for hyperlipemia and lean seed), lung deficiency and dry cough, pulmonary tuberculosis, and various symptoms of aging (fatigue, early white beard and hair, kidney essence deficiency, waist soreness and softness). The sealwort has high sugar content and high nutritive value, and is an ideal medicinal and edible raw material. Rhizoma Polygonati mainly contains chemical components such as steroid saponin, polysaccharide, flavone, and alkaloid.

Fresh/raw rhizoma Dioscoreae Zingiberensis has a numb taste, stimulates throat, and is processed without being directly added into medicine. The steamed rhizoma Polygonati has no pungent taste, reduced irritation to throat, easy dissolution of effective components, and enhanced spleen invigorating and lung moistening effects. In addition, yellow wine-processed rhizoma Polygonati can enhance its tonifying effect and make it delicious but not greasy. The honey processing is one of the traditional processing methods of the sealwort, but the honey is not easy to enter the sealwort, the process uses stevia rebaudiana water to replace honey, the stevia rebaudiana is a natural sweetener which is 200 times of the sweet taste of granulated sugar, can correct the numb taste of the sealwort, has the effects of reducing blood pressure and blood sugar, and can assist the sealwort to play the roles of reducing blood pressure and blood sugar.

In the prior production, the polygonatum sibiricum is processed and processed by nine times of steaming and nine times of drying, the steaming time is long, the drying process is simple and extensive, the moisture is not easy to control, and the appearance, color, shape and the like of the polygonatum sibiricum are easy to be uneven. And the past patents (CN 201810527497.0-a rhizoma polygonati extract rhizoma polygonati sugar and a preparation process thereof, CN 108835353A-a rhizoma polygonati sugar preparation formula and a preparation process thereof): 1. at present, the existing polygonatum sibiricum soft sweets processing technology mostly needs to carry out the crushing, extraction and the like of polygonatum sibiricum, the preparation technology is complicated, equipment such as a crusher, a stirrer and the like is needed, the processing time is long, and manpower and material resources are consumed. 2. And various chemical reagents are required to be added in the processing process for color matching, seasoning, corrosion prevention and the like.

Rhizoma polygonati has dual purposes of medicine and food, and has low requirements on soil environment, so the rhizoma polygonati becomes important economic crops for farmers to get rid of poverty and become rich in many poor areas in China at present, but most of the rhizoma polygonati cultivated in production places are directly dried in the sun and sold as raw materials at low price, the income of the farmers is not remarkably increased, and the risk of price reduction is also caused along with the continuous expansion of cultivation areas. Therefore, a method for improving the income of farmers at the front end of the polygonatum kingianum industrial chain is urgently needed to be found, and meanwhile, the method is simple and practical, does not need to purchase a large amount of high-precision equipment, does not need a complex process, is suitable for popularization in vast polygonatum kingianum planting rural cooperative society, and is also guaranteed in market sales in combination with the rise of rural tourism.
