Embodiment 1

[0025] Pump 20 tons of waste mash protein into the reaction kettle, and then pump 1 ton of waste gulonic acid mother liquor. After stirring, the pH value is 5.0. Heat the reaction kettle to 90°C, keep it warm for 1 hour, and keep it still. Pump out the supernatant in the reactor (about 17 tons), pass through 40 kg of slaked lime Ca(OH) 2 Adjust the pH to 7.2, evaporate and concentrate until the polypeptide and amino acid account for about 9wt%, and then add appropriate amount of trace elements and crop stalks according to the organic fertilizer standard to become the polypeptide organic fertilizer. In this embodiment, the trace elements may be Fe, Zn, Mn, Mo and B, and by weight percentage, Fe 1.2%, Zn 0.8%, Mn 0.2%, Mo 0.1%, B 0.1%. The precipitated part in the reaction kettle is pumped into the plate and frame filter press, and after being filtered, it is dried with a dryer and crushed to make bacterial protein (about 1.5 tons).

Embodiment 2

[0029] Pump 20 tons of waste mash protein into the reaction kettle, and then pump 3 tons of waste azuronic acid mother liquor. After stirring, the pH value is 4.0. Heat the reaction kettle to 50°C, keep it warm for 2 hours, and keep it still. Pump out the supernatant in the reaction kettle (about 18 tons), adjust the pH to 7.2 through 100 kilograms of slaked lime, and concentrate through evaporation to: polypeptides and amino acids account for about 7.6wt%, and then add appropriate amount of trace elements and Crop stalks become polypeptide organic fertilizers. In this embodiment, the trace elements may be Fe, Zn, Mn and B, and by weight percentage, Fe 1.0%, Zn 0.7%, Mn 0.1%, B 0.2%. The precipitated part in the reaction kettle is pumped into the plate and frame filter press, and after being filtered, it is dried with a dryer and crushed to make bacterial protein (about 1.0 tons).

Embodiment 3

[0033]Pump 20 tons of waste mash protein into the reaction kettle, and then pump 2 tons of waste gulong acid mother liquor. After stirring, the pH value is 3.0. Heat the reaction kettle to 40°C, keep it warm for 12 hours, and keep it still. Pump out the supernatant in the reaction kettle (about 15 tons), adjust the pH to 7.2 with 65 kg of slaked lime, and concentrate through evaporation to: peptides and amino acids account for about 10wt%, and then add appropriate amount of trace elements and crops according to the organic fertilizer standard Straw becomes polypeptide organic fertilizer. In this embodiment, the trace elements may be Fe, Mn and B, and by weight percentage, Fe is 1.5%, Mn is 0.7%, and B is 0.3%. The precipitated part in the reaction kettle is pumped into the plate and frame filter press, and after being filtered, it is dried with a dryer and crushed to make bacterial protein (about 1.7 tons).

Abstract

The invention relates to a method for producing mycoprotein and polypeptide organic fertilizer by waste fermented mash and gulonic acid mother solution formed in the vitamin C production technology, which belongs to the field of biotechnology and waste resource utilization technology, and comprises the following steps: adding 5 to 20 parts of gulonic acid mother solution in 100 parts of waste vitamin C fermented mash protein, adjusting pH value to 2.0 to 5.0, and hydrolyzing for 0.5 to 12 hours under the temperature of 40 to 70 DEG C. On the one hand part of protein in fermented mash protein is hydrolyzed to become polypeptide and amino acid to dissolve in water, through adjusting pH value and appropriate concentration, right amount of trace element is added, obtaining polypeptide organic fertilizer, on the other hand the rest protein in mash protein is precipitated, and the precipitated protein is made into mycoprotein through filter-pressing, drying and smashing. The invention recycles the vitamin C fermentation industry waste to produce mycoprotein and polypeptide organic fertilizer, thus not only solving the problem of industrial pollution, but also providing organic fertilizer and feed protein for agricultural production.

Description

technical field [0001] The invention relates to a method for producing bacterial protein and polypeptide organic fertilizer by using waste fermented mash of vitamin C and mother liquor of gulong acid, and belongs to the technical field of biotechnology and waste resource utilization. Background technique [0002] Bacterial proteins are also called microbial proteins and single-cell proteins. According to different production raw materials, it can be divided into petroleum protein, methanol protein, methane protein, etc.; according to the type of bacteria produced, it can be divided into bacterial protein, fungal protein, etc. In 1967, at the first worldwide conference on single-cell proteins, microbial bacterial proteins were collectively referred to as single-cell proteins. Single-cell protein contains rich nutrients, among which the protein content is as high as 40wt% to 80wt%, which is 10% to 20% higher than that of soybean, and more than 20% higher than that of meat, fi...
