Abstract
The invention relates to a detoxifying method for cassava leaves. The detoxifying method comprises the following steps of (1) collecting fresh cassava leaves, thoroughly cleaning the collected cassava leaves, drying the cleaned cassava leaves, and cutting up the dried cassava leaves; (2) respectively weighing a certain amount of white granulated sugar, a certain quantity of the cassava leaves and a certain amount of drinking water (the raw materials in parts by weight comprise 1-2 parts of the white granulated sugar, 3-4 parts of the cassava leaves and 10-12 parts of the drinking water), putting the raw materials in a clean conditioner, performing uniform mixing, and then performing sealing; and (3) putting the container in the shade, performing fermentation for 3-7 days and realizing fermenting and detoxifying of the cassava leaves. The method provided by the invention can enable linamarin toxicants in the cassava leaves to be acidified, so that the cassava leaves in which the content of hydrocyanic acid is smaller than or equal to 10mg/kg are obtained, and relative standard requirements of China are completely met.
Description
Technical field
The method that the present invention relates to the fermentation detoxification of a kind of leaf of Maninot esculenta crantz..
Background technology
Maninot esculenta crantz. is that one is grown in shrub tropical, semi-tropical, in the world state's main product such as Brazil, Thailand, India, China Guangxi,
The ground such as Guangdong, Hainan growing surface is bigger.In the developing country of torrid areas, Maninot esculenta crantz. is mainly used as grain, mainly uses in China
Make feedstuff and produce starch.The tuber of Maninot esculenta crantz. is typically used as producing starch, and its leaf is principal by product, the yield ratio of leaf of Maninot esculenta crantz.
More considerable, per hectare soil can produce leaf of Maninot esculenta crantz. 10～15 tons, is equivalent to every per mu yield leaf of Maninot esculenta crantz. 700～1000 kilograms.
Leaf of Maninot esculenta crantz. has the protein of high level and abundant mineral element, and after leaf of Maninot esculenta crantz. air-dries, moisture is 9.7%, containing thick
Albumen 13.6%, crude fat 7.1%, crude fibre 19.7%, nitrogen-free extract 47.2%, coarse ash 7.5%, leaf of Maninot esculenta crantz. aminoacid
In except methionine is less than in addition to critical level, and other amino acid content enriches, and Compositional balance is more much higher than some high quality forages,
It is a kind of comprehensive nutrition, high-yield feedstuff.
Blue or green dry cassava leaf meal, compared with the thick protein of quality alfalfa grass meal, exceed a lot, as cassava leaf meal crude protein reaches
27%, alfalfa only has 20.40%, and metabolizable energy value relatively alfalfa leaf meal is suitable (leaf of Maninot esculenta crantz. 1.55Mcal/kg, Herba Medicaginis 1.63Mcal/kg),
Crude fiber level slightly higher (leaf of Maninot esculenta crantz. 24.7%, Herba Medicaginis 22.70%), relative metabolic rate is less than alfalfa meal (leaf of Maninot esculenta crantz. 27.9%, Herba Medicaginis
Leaf 34%), so, from overall trophic level assessment, the nutritive value of leaf of Maninot esculenta crantz. is suitable with alfalfa meal.
The noxious substance of fresh leaf of Maninot esculenta crantz. is core of Caulis et Folium Lini hardship glycosides, and core of Caulis et Folium Lini hardship glycosides produces free hydrocyanic acid, hydrogen after gastric acid hydrolyzes
Cyanic acid easily causes people's alimentary toxicosis, affects health.In leaf of Maninot esculenta crantz. the height of cyanide content with Cassava Cultivars difference,
The factors such as the Maturity of leaf, the nutrition of plant and weather conditions are correlated with, usually 200～800 milligrams HCN/ kilogram fresh leaf weight,
When utilizing leaf of Maninot esculenta crantz. to make food or feedstuff, it should be noted that detoxification.
Summary of the invention
The method that it is an object of the invention to provide the fermentation detoxification of a kind of leaf of Maninot esculenta crantz..
To achieve these goals, present invention employs techniques below scheme:
A kind of leaf of Maninot esculenta crantz. fermented detoxification method, comprises the steps:
(1) collect fresh leaf of Maninot esculenta crantz. and clean, dry, shred；
(2) by weight, weigh white sugar 1～2 parts, leaf of Maninot esculenta crantz. 3～4 parts and water 10～12 parts, be placed in clean appearance
Device is interior and mixes, and seals；
(3) container is placed in the cool, ferments 3～7 days, it is achieved the fermentation detoxification to leaf of Maninot esculenta crantz..
Compared with prior art, the beneficial effect that the present invention possesses:
The method that the present invention provides, simple to operate, after leaf of Maninot esculenta crantz. is fermented, harmful components are acidified, and reach relevant national standard
Nutrient component damages in requirement, and leaf is less, and the leaf of Maninot esculenta crantz. quality after fermentation is soft, good palatability, and poultry are liked to eat, for poultry
Animal husbandry provides a kind of safety, the feedstuff of high-quality；Meanwhile, it is also beneficial to make full use of the leaf of Maninot esculenta crantz. of high yield, reduces environmental pollution,
Promote the sustainable development of agricultural.
