Problems solved by technology

Among them, during the pulverization, beating and sedimentation process of sweet potatoes, phenolic substances in sweet potatoes are prone to oxidative browning, and the mixture of other colored impurities makes the vermicelli black, dark in color and lower in quality.
In the step of drying powder, the natural drying method is mostly used in the southern region, but in rainy weather, the drying speed is slow, coupled with the high temperature and high humidity in the south, it is prone to deterioration, and many producers have to transfer the vermicelli to the vermicelli in rainy weather. Into the greenhouse to continue drying, which will increase energy use and increase production costs
In addition, with the improvement of people's living standards, the requirements for high-level nutritional and health-care foods are getting higher and higher. Vermicelli and vermicelli containing a single starch component can no longer meet people's requirements. Increase the health care effect of sweet potato powder, overcome the problem of single health care effect of existing sweet potato powder, and meet the needs of the public

Abstract

The present invention discloses a manufacture technology of health-care sweet potato vermicelli and relates to the technical field of food processing. The method comprises the following steps: sweet potato selecting and washing, beating, precipitating, sweet potato starch and water mixture preparing, steaming to obtain vermicelli and vermicelli air-drying; wherein the steps of the beating, precipitating, etc. all use a tea leaf extract for treatment; when the sweet potato starch and water mixture is prepared, the tea leaf extract, a pumpkin seed extract, a perilla seed extract and a grape seedextract are added; and besides, before the air-drying, a mint extract is firstly sprayed on the vermicelli. By optimizing the manufacture method, the manufacture technology suppresses formation of dark brown materials in the sweet potato vermicelli, so that the prepared sweet potato vermicelli is not black, translucent, bright and pure in color and luster, and improved in quality; at the same time, in the natural air-drying process, the sweet potato vermicelli is prevented from being rancid and deteriorated in cloudy and rainy weather; and in addition, the sweet potato vermicelli also has health-care effects of losing weight, lowering blood fat, lowering blood pressure and lowering blood sugar, and is especially suitable for the consumption of the elderly.

Description

【Technical field】 [0001] The invention relates to the technical field of food processing, in particular to a manufacturing process of health-care sweet potato flour. 【Background technique】 [0002] Sweet potato flour is a traditional specialty food in my country. It is rich in protein, sugar, fat, phosphorus, calcium, iron, carotene, vitamins, linoleic acid, amino acids and other nutrients. It has a special flavor and taste and is deeply loved by consumers. Studies have shown that sweet potato flour is very low in calories, and it is not easy to gain weight if you eat more. [0003] At present, the main raw material for making sweet potato flour is sweet potato, and some auxiliary materials will be added together. The main production process is: potato selection→peeling→cleaning→beating→sedimentation→making cornstarch→steaming powder→sun powdering→finished product. Wherein sweet potato is in crushing beating and sedimentation process, the phenolic substance in sweet potato ...
