Abstract

The application provides a method for treating crops, which belongs to the field of crop processing and treatment. The method can be used for improving the added value or medicinal value of the effective parts of crops.

Description

Crop treatment method and product thereof
Technical Field
The application belongs to the field of crop processing and treatment, and particularly relates to a crop processing method and a crop product.
Background
Dioscorea (Dioscorea polystachya Turczaninow) is a plant of Dioscorea of Dioscoreaceae, and is entangled with grass vine. The tuber of yam is also called "yam" and is rich in starch and can be eaten by vegetables. Chinese yam can also be used as a medicine, and has sweet, warm and flat nature, no toxicity, mainly treats injuries, supplements deficiency and deficiency, eliminates cold and heat evil, supplements middle-jiao, benefits qi, grows muscles and strengthens yin. The bulbil between the axilla of the yam is a bulbil, is kidney-shaped or oval-shaped, has different long circles, is also called as 'yam egg', 'yam seed', 'yam bean' in folk, and the like, and is distributed in North China, northwest China, eastern China and China. The fructus phyllanthi has the effects of improving intelligence, tranquilizing, prolonging life, strengthening body constitution, nourishing lung, nourishing yin, invigorating spleen, replenishing kidney essence, relieving cough and asthma.
Although it is thought that the yam and yam beans contain dopamine, hydrochloric acid, yam glycoside and other substances which can be used for reducing blood sugar, blood pressure or other cardiovascular and cerebrovascular diseases, clinically, the crop has no obvious effect on improving or treating disease symptoms, and the reason is probably that the content of the active ingredients is lower than the whole quality of the crop, and the yam and yam beans also contain higher starch, which can be converted into polysaccharide and glucose after metabolism, so that the blood sugar is increased.
Solanaceae and Nelumbo nucifera are also common crops, and tubers such as potato or lotus root are rich in starch, and can be metabolized into polysaccharide and glucose after being eaten in a large amount, so that the blood sugar concentration is affected.
Therefore, development is needed to increase the content of beneficial components in crops to improve the edible and medicinal values of crops and the nutritional and health care values of foods.
In addition, at present, the yam beans are mainly used as yam bean sugarcoated haws or are sold directly in a small amount in the supermarket, but due to low added value of products, a large amount of yam beans are directly discarded as waste. The effective storage of agricultural products such as potatoes, lotus roots, yams and the like is also related to national folk life. Therefore, the development of a simple method capable of improving the added value of agricultural products is also helpful to increase the income of farmers and the commercial value of crops.
