CN103168917A - High-protein feedstuff produced by using persimmon - Google Patents

Abstract

The invention relates to a high-protein feedstuff produced by using persimmon. The feedstuff is prepared from 1000kg of sweet persimmons, 2kg of aspergillus niger, 2kg of oxalic acid, 5kg of acidic protease, 5kg of active dry yeast, and 1kg of a preservative. According to the invention, the 1000kg of ripe persimmons are crushed, and are dispersed into a persimmon pulp by using a high-speed dispersion machine; oxalic acid is added, such that a PH value is regulated to 3.5-4.5; aspergillus niger is added, and the temperature is increased to 32 DEG C; the active dry yeast is added, and the mixture is uniformly mixed by stirring; sealed fermentation is carried out for 4-5 days; when sugar content in the persimmon pulp is reduced to below 0.5%, the fermentation is stopped; water and ethanol in the fermented persimmon pulp are removed by filtering; filtering slag is bake-dried; components are adjusted, and the preservative and the acidic protease are added; water content is controlled below 10%, and the feedstuff is obtained. According to the invention, sugar in the sweet persimmon is utilized, and is converted into protein by using a biological enzyme technology. The protein content is no lower than 18%. The feedstuff is a green and environment-friendly novel high-quality feedstuff.

Description

A kind of high protein feed of producing with persimmon

Technical field

The invention belongs to the processing method of feed.

Background technology

Along with China's rapid development of economy, the people's living standard improves day by day, and common people sharply increase the demand of poultry and egg, thereby drives China's aquaculture high speed development, also brings unprecedented great development to Feed Enterprise simultaneously.Through high speed development in recent years, a unprecedented prosperity scene has appearred in China's feed processing industry, still, along with grain price constantly raises, the rising of human cost has brought very large cost pressure to feed industry, also cause simultaneously price rise, bring destabilizing factor for China's economic development.

Summary of the invention

In order to reduce the feedstuff cost, thereby reduce aquaculture cost, stable price then the invention provides a kind of high protein feed of producing with persimmon.

Technical scheme of the present invention is: batching:

1. sweet persimmon is 1000 kilograms;

2. black-koji mould is 2 kilograms;

3. oxalic acid is 2 kilograms;

4. acid protease is 5 kilograms;

5. active dry yeast is 5 kilograms;

6. anticorrisive agent is 1 kilogram.

Described anticorrisive agent refers to KF88.

Production technology of the present invention: first that the sweet persimmon of maturation is broken, then be dispersed into the persimmon slurries with the high speed dispersion machine;

Adding oxalic acid to make PH is 3.5--4.5;

Then add black-koji mould, be warming up to 32 degree;

Then add active dry yeast to stir, sealing fermentation 4--5 days; The sugared content of persimmon slurries the inside is reduced to below 0. 5 percent, fermentation ends;

With the water in the persimmon slurries of fermentation ends, alcohol removes by filter, and then with the filter residue oven dry, after adjusting component, adds anticorrisive agent, and below ten of percent water leave it at that.

Owing to adopting persimmon as raw material, its raw material output is huge, and price steadiness belongs to non-grain farmer crop, can not fluctuate because of provision price, causes feed price unstable.In addition, present persimmon only has a very little part as the fruit utilization, so price comparison is stable, is a very favourable condition to large-scale production.

The present invention utilizes the sugar of sweet persimmon the inside, with biological enzyme technology, sugar is changed into protein, and its protein content 〉=18% is a kind of novel high-quality feed of environmental protection.

The specific embodiment

Embodiment: production technology of the present invention: first that the sweet persimmon of 1000 kilograms of maturations is broken, then be dispersed into slurries with the high speed dispersion machine;

Adding oxalic acid to make PH is 3.5--4.5;

Then add black aspergillus, be warming up to 32 degree;

Then add active dry yeast to stir, sealing fermentation 4--5 days; The sugared content of persimmon slurries the inside is reduced to below 0. 5 percent, fermentation ends;

With the water in the persimmon slurries of fermentation ends, alcohol removes by filter, and then with the filter residue oven dry, after adjusting component, adds acid protease and anticorrisive agent, and below ten of percent water leave it at that.

Claims (3)
