The main value of banana taro
Banana lotus root is a good material to beautify the courtyard because of its lush stems and leaves, long leaf viewing period and simple management.
The development and utilization of banana taro mainly focuses on the production of starch, and the development of starch deep-processed products and food items such as vermicelli and vermicelli. Banana taro is processed into starch, or dried and fermented to make wine. The wine yield is 60-70%, which is higher than that of grain. Distiller's grains and banana taro stalks are also feed for pigs. Generally, 2.5 kg of banana taro starch can produce 0.5 kg of monosodium glutamate, as well as starch sugars such as glucose and sorghum maltose for oral administration and injection, and various non-staple foods such as lotus root starch. Its pedicel has a sweet taste. As a vegetable, it can be sliced or shredded; Or blanch in boiling water and then cold mix, or pickle.
The rhizome and tubers of banana taro mainly contain starch, and each 100g tuber contains starch 12 ~ 14g. Its roots and tubers are sweet, light and cool, and have the effect of clearing away heat and promoting diuresis.
In textile industry, compared with grain starch sizing, banana taro starch sizing has the characteristics of high adhesion and good smoothness. Banana taro starch can also be used in papermaking, shoemaking, hat making, clothing and stationery. Its stem and leaf fibers can be used as raw materials for papermaking or twisting ropes. ?
