Embodiment 1

[0014] 1. Strains: N. Sitophila strain No. 17

[0015] 2. Medium and culture conditions:

[0016] Slant medium (PDA slant): 2% glucose, 2% agar, prepared with 20% potato juice, natural pH, cultured at 28°C for 3 days.

Embodiment 2

[0018] 1. Incline cultivation is the same as in Example 1

[0019] 2. Main detection methods

[0020] (1) Determination of protein content: Folin-phenol method

[0021] (2) Determination of antioxidant activity: pyrogallol autoxidation method

[0022] 3. Determination of solid fermentation medium: using the orthogonal design experiment method, put 5g of solid dry basis in a 250mL triangular flask, bandage the bottle mouth for sterilization, and inoculate 1.0×10 spores per bottle 6 One, culture temperature 28±0.5℃. After culturing for 4 days, the antioxidant activity of the fermentation product extract and the protein utilization rate of the bacteria were measured. 4 parallels were done for each condition. The results were analyzed using SAS6.12 software. Determine the optimum fermentation medium composition: the ratio of corn gluten meal to bran is 3:2; the ratio of medium dry base to water is 1:1.5; MgSO 4 The ratio to the dry base of the medium is 0.01%.

Embodiment 3

[0024] 1. Incline cultivation is the same as in Example 1

[0025] 2, fermentation medium is the same as embodiment 2

[0026] 3. Determination of fermentation conditions

[0027] The effects of fermentation temperature, time and inoculation amount on protein content and antioxidant activity were studied by single factor experiment. Determine the best fermentation conditions: the inoculum amount is 1.0×10 6 piece / g material, the fermentation temperature is 25°C, and the fermentation time is 4 days.

Abstract

The present invention discloses a new-type feed and its preparation method. Said new-type feed is made up by using corn protein powder and wheat bran as raw material and using neurospora strain No.17 as fermentation zymophyte seed through a certain preparation process. Said preparation process includes the following steps: making slant cuture and solid fermentation, the ratio of corn protein powder and wheat bran is 3:2, the ratio of dried culture medium and water is 1:1.5 and the ratio of MgSO4 and culture medium is 0.01%, and making culture for 4 days at 25deg.C so as to obtain the invented new-type feed. The resolubility of protein in said new-type feed can be up to above 20%, and the antioxidant activity of said new-type feed can be up to above 200U / mL. Said new-type feed has high nutritional value.

Description

technical field [0001] The invention relates to a novel feed produced by fermenting neurospora californica corn yellow powder and a preparation method thereof, belonging to the technical field of feed production. Background technique [0002] The annual output of my country's feed industry ranks second in the world after the United States, and its output value ranks 20th among the 41 major industries of my country's national economy, becoming one of the basic industries of the national economy. In this output, pig feed accounts for 30%, laying poultry accounts for 20%, meat poultry accounts for 30%, aquatic feed accounts for 10-15%, and others account for 5%. According to estimates by experts, at present, my country's feed industry is short of 10 million tons of protein feed and 30 million tons of energy feed. Therefore, it is necessary to extensively develop new protein sources. my country is rich in plant protein resources, with the characteristics of wide sources and low...
