Problems solved by technology

These substances are feed anti-nutritional factors, which have toxicity, bad smell and bitter taste, which will reduce the palatability of potato vines as feed, and even cause animal poisoning, so their feeding value is greatly limited
[0003] Finding a cheap method to separate the toxic components and feedable components in potato vines, so that both can be used, can solve the problem of wasting the abundant potato vine resources in Inner Mongolia, and the serious shortage of high-quality green fodder for cattle and sheep the puzzle

Abstract

The present invention discloses process of extracting steroid alkaloid from potato vine and the use of the intermediate product as silage. The process of extracting steroid alkaloid from potato vine includes the step of fermenting potato vine, and the step of extracting steroid alkaloid. The present invention can extract steroid alkaloid from potato vine while producing high quality silage.

Description

Technical field: [0001] The invention relates to a method for extracting steroidal alkaloids from potato vines and the use of intermediate products as silage, belonging to the fields of medicine manufacturing and feed processing. technical background: [0002] The Inner Mongolia Autonomous Region is one of the main potato producing areas in my country. The sown area and total output both rank first in the country. In recent years, with the pull of the international and domestic potato markets and the development of potato production, the potato industry in Inner Mongolia has become a region with regional economic characteristics. important industry. Potato vine is a by-product of the potato planting industry. The output of fresh vine per mu can reach about 1,000 kilograms, and the annual output of the whole region is 8 million tons. Although potato vines can be used as green manure, it is one of the main causes of potato late blight damage year after year, and the gains outw...
