Embodiment 1
[0036] Weigh 100kg of Huaxiang seeds, grind them 1 to 3 times on an ordinary grinder, add them to 300L of warm water with a water temperature of 30 to 40°C, stir well, and then use 0.5moL / L hydrochloric acid or 0.5moL / L sodium hydroxide aqueous solution Adjust the pH of the feed solution to 6, add amylase and cellulase to a final concentration of 60U / L, and perform enzymatic hydrolysis for 4 hours; then add temperature-sensitive acidic protease (with rapid inactivation characteristics above 45°C) to the enzymolysis solution to The final concentration is 80U / L, enzymolysis is carried out for 3 hours, and the temperature is kept above 55°C for 35 minutes to obtain feed solution Ⅰ. The feed liquid I is centrifuged on a decanter centrifuge to obtain liquid and wet residue, and the liquid directly enters the disc separator to separate the oil of the fragrant tree seed and waste water I. Drying the obtained fenugreek seed oil under vacuum condition, filtering after standing still to...
Embodiment 2
[0038]Weigh 200kg of Huaxiang seeds, grind them three times on an ordinary grinder, add 1500L of effluent I, heat to about 30-40°C, stir well and then adjust with 0.5mol / L hydrochloric acid or 0.5mol / L sodium hydroxide aqueous solution The pH of the feed solution is 5.5, add amylase and cellulase to a final concentration of 50U / L, and after 3 hours of enzymolysis, add temperature-sensitive acidic protease (rapid inactivation characteristics above 45°C) to the enzymolysis feed to The final concentration is 80U / L, enzymatic hydrolysis for 3 hours, and incubation at 55°C for 35 minutes to obtain feed solution II. The feed liquid II is centrifuged on a decanter centrifuge to obtain liquid and wet residue, and the liquid directly enters the disc separator to separate the oil and waste water II. Drying the obtained fenugreek seed oil under vacuum condition, filtering after standing still to obtain the finished elixir tree seed oil, and inspecting the finished oil. The obtained wast...
Embodiment 3
[0040] Take 100kg of waste water and 450kg of waste residue produced by untreated circulating oil production as raw materials, make the water content reach about 35%, add 40kg of Bacillus subtilis powder for feed purchased in the market, and cultivate aerobic fermentation at 30-40°C for 48 hours. It is determined that the total free amino acid content reaches 14.4g / 100g, which is 37.6% higher than that of waste residue.
