Problems solved by technology

[0005] This study only conducted a preliminary screening of tomato residue fermentation strains, screened and obtained several target strains, which can be used to ferment tomato residue to produce single-cell protein feed, but did not conduct optimization of tomato residue solid fermentation parameters and fermentation process discussion , is incomplete and immature in the fermentation process

example 1

[0021] (1) Strain and source

[0022] Candida utilis (Candida utilis), Geotrichum candidum, Saccharomyces cerevisiae, Aspergillus oryzae, Aspergillus fumigatus, strains were purchased from the China Industrial Microorganism Collection .

[0023] (2) Preparation of composite microorganisms

[0024] Original seed test tube activation-triangular flask expansion-seed tank culture-fermenter culture.

[0025] The described enzyme mother bacteria (Candida utilis, Geotrichum candidum, Saccharomyces cerevisiae) medium is 5°Bé wort medium: 100g of barley malt is crushed, put into a 1000ml beaker, 400-500ml of water is added, and cultured at 60°C at a constant temperature 4 to 5 hours, 8 layers of gauze filter. Add 20ml of water to an egg white, stir to a large amount of foam, pour it into the filtrate, boil, keep boiling for 5 minutes, filter with 8 layers of gauze to obtain clarified wort, measure the sugar content with a sugar meter, and dilute to 5°, 112.6°C Sterilize for 30 minutes and s...

example 2

[0036] (1) Strain and source: the same as in Example 1.

[0037] (2) Preparation of composite microorganisms: the suspensions of Candida utilis, Geotrichum candidum, Saccharomyces cerevisiae, Aspergillus oryzae and Aspergillus fumigatus were mixed at a ratio of 1:1:0.5:2.0:2.0 to obtain a composite microorganism suspension. Others are the same as in Example 1.

[0038] (3) Preparation of fermentation raw materials: fresh tomato residue accounted for 85%, bran in auxiliary materials accounted for 12%, urea 1.5% and ammonium nitrate 1.5%.

[0039] (4) Strain inoculation and preparation process

[0040] The composite microorganisms are converted into a solid mixed microbial agent by using sterilized wheat bran at an inoculum amount of 3% by weight of the raw material through conventional carrier technology.

[0041] After mixing the solid mixture with fresh tomato residue, ammonium nitrate and urea, solid fermentation is carried out. The solid fermentation stack height is 80cm, the fermen...

Abstract

The invention discloses a manufacturing method for producing bioprotein feed using tomato pomace. The manufacturing method comprises mixing fermentation materials by mass percent, including 80-85% of tomato pomace, 12-18% of wheat bran, 1-1.5% of urea and 1-1.5% of ammonium nitrate; then preparing a solid fermentation culture medium; inoculating composite microorganism composed of saccharomycetes and mould; fermenting for 48-72 hours; and drying and crushing or granulating the ferment so as to obtain the bioprotein feed... By adopting the tomato pomace to produce the bioprotein feed, the problem that the resource for bioprotein feed is insufficient in China is alleviated, and the investment cost of the feed is saved, so that the economic income of peasants is increased.

Description

Technical field [0001] The invention relates to a method for producing biological protein feed using tomato residue. Background technique [0002] In recent years, with the development of animal husbandry production, the shortage of protein feed has become increasingly prominent, which has become one of the bottlenecks restricting the development of animal husbandry in my country and the world. In order to alleviate the tension of domestic protein feed and meet the demand for protein feed resources in the breeding industry and feed industry, my country's soybean imports for soybean meal production have increased to as much as 30 million tons, even exceeding domestic output. How to develop new protein feed resources is an urgent task for my country's feed industry. [0003] As a by-product of tomato paste processing, tomato residue has an annual output of more than 500,000 tons nationwide. The production of fresh tomato residue is seasonal, with high moisture content (above 75%), ...
