Fuyuan's konjac 300-word composition

Konjac, also known as konjac, is a perennial herb of Araceae. There are about 170 species in the world, mainly distributed in Asia and Africa. China is rich in konjac resources, with more than 20 species. With its unique geographical environment and climatic conditions, Yunnan has the reputation of "plant kingdom", with 17 konjac varieties, accounting for 63% of the national konjac germplasm resources. Fuyuan, on the other hand, is dominated by konjac varieties, with good quality and good color. It is regarded as a fine product by konjac brands and has set a record of per mu yield 1 1 ton.

The Chinese nation is the first nation to study and utilize konjac. As early as the Western Han Dynasty, the Shennong Herbal Classic confirmed for the first time that konjac was a medicine for treating diseases. Later, in the Yuan, Ming and Qing Dynasties, there were records of konjac used as medicine, which was used to satisfy hunger in famine years. Compendium of Materia Medica also systematically introduces the ecological environment, cultivation methods, indications, taking methods and cooking techniques of konjac. The Dictionary of Modern Chinese Medicine also affirmed that konjac, as a traditional Chinese medicine, has the functions of detoxification, bacteriostasis, phlegm-resolving, stagnation-resolving and blood stasis-removing. The traditional way of eating konjak in China is to manually process fresh konjak or konjak horn into gray-black konjak tofu to eat. This kind of indigenous konjac tofu often affects the health care function of konjac because of a large amount of alkali added.

The effective component of Amorphophallus konjac is glucomannan contained in bulbs. From the anatomical structure of the bulb, we can see that the bulb contains a large number of large heterogeneous cells, and the heterogeneous cells contain glucomannan. By removing starch and other components around heterogeneous cells, the crude product of konjac glucomannan-refined konjac powder can be obtained. The refined konjac powder can be further purified and refined, and processed into konjac micropowder with higher quality and more convenient use.

Konjac glucomannan is a kind of high molecular polysaccharide, which has many physical and chemical properties such as water solubility, thickening, stability, suspension, gelation, film forming and adhesion. Therefore, konjac is widely used in medicine, food, drilling, papermaking, building materials, printing and dyeing, daily chemical, environmental protection and other industries.

Before 1990s, Fuyuan Amorphophallus konjac was still scattered. After 1990s, with the extensive development and utilization of konjac products, the market demand at home and abroad increased, and towns and villages such as Laochang and Fucun in Fuyuan County began to plant on a large scale. Villages and towns such as Huangnihe, Shilianshan and Mohong also use idle land for moderate-scale planting, which has achieved good economic benefits. 1998, the whole county planted konjac 1 134 mu.

In 20001year, the fifth plenary session of the ninth session of the county Committee listed konjac as one of the characteristic economies, strengthened the leadership of konjac production, increased technical guidance and financial support, and Fuyuan konjac ushered in the spring of development. In 200 1 year, the county planted konjac 1. 1 10,000 mu, with a total output of 52.77 million kilograms and an output value of 38 1.8 million yuan. In 2002, it planted 15800 mu, produced 7 1 10000 kg of fresh taro, and realized an output value of 49.77 million yuan. It is planned to plant 20,000 mu of konjac in 2003. By 2007, the planting area of konjac in the county will reach 50,000 mu, making it the largest gathering place for konjac production, processing and sales in the province. With the improvement of human material life and health care level, konjac industry will have a broader prospect and become a sunrise industry in 2 1 century.
