Embodiment 1

[0029] 1. Obtaining lean pork

[0030] Provided by a pig farm.

[0031] 2. Research on acid hydrolysis conditions

[0032] 1) Sulfuric acid concentration: set different sulfuric acid concentrations (3mol / L, 4mol / L, 5mol / L and 6mol / L) for acid hydrolysis at 80°C, and the material ratio is 1:2 (1g lean pork: 2mL sulfuric acid) , acid hydrolysis time 5h, gauze filter, 50 ℃ drying to determine the degradation rate of lean pork.

[0033] Result: by figure 1 It can be seen that when the acid concentration is higher than 5mol / L, there is no significant difference in the degradation rate of pig lean meat, and the sulfuric acid concentration of 5mol / L is determined as the optimal acid concentration.

[0034] 2) Acid hydrolysis temperature: set different temperatures (60°C, 70°C, 80°C and 90°C) at a sulfuric acid concentration of 5mol / L, a material ratio of 1:2 (1g lean pork: 2mL sulfuric acid) and an acidolysis time of 5h Acid hydrolysis under conditions, gauze filtration, drying a...

Abstract

The invention discloses a liquid amino acid compound produced by dead porcine proteins and an application of the compound. The liquid amino acid compound is obtained by acidifying lean meat by adding sulfuric acid. The liquid amino acid compound produced by acidifying lean meat by adding sulfuric acid is rich in various free amino acids, and the contents of the free amino acids, soluble polypeptide and soluble albuminous total nitrogen are high. The compound diluted as a liquid agricultural amino acid fertilizer leaf fertilizer is sprayed to cucumber, brassica chinensis and radish plants, so that the compound has a very good growth promoting effect. The invention provides a production method of a liquid agricultural amino acid by acidifying lean meat by adding sulfuric acid. The process is simple and the demand on the equipment is low. Compared with a conventional dead pig treatment process, the production method disclosed by the invention has the characteristics that the produced amino acid as the liquid agricultural amino acid fertilizer has the advantages of low treatment cost, and the porcine lean meat resources can be effectively recycled. The compound disclosed by the invention has importance meaning for preserving the ecological environment, effectively solving the problem of treating dead pigs, protecting physical health of people and improving the additional value of agricultural products.

Description

technical field [0001] The invention belongs to the field of resource utilization of waste, and relates to a liquid amino acid compound produced by utilizing sick and dead pig protein and its application. Background technique [0002] In 1908, Frenchman Lutz made the world's first amino acid absorption aseptic test, which proved that plants can absorb amino acids. After the 1950s, with the application of isotope tracing technology and microautoradiography technology, the research on plant amino acid nutrition began to make more in-depth progress. Xu Yulan et al. used 15N to label glycine and leucine under sterile culture conditions, and found that single or mixed application could significantly increase the dry weight of rice seedlings. Glycine increased the weight of rice seedlings by 23.7%, and leucine increased the weight by 30.0%. , the mixed treatment of the two increased the weight by 41.2%. Liu Qingcheng and others sprayed celery stems and leaves with amino acid mix...
