Problems solved by technology

However, a large amount of waste water will be produced in the process of producing fragrant tree seed oil by aqueous enzyme method. Since the waste water contains a large amount of sugars, proteins and other substances, the traditional waste water treatment method cannot be completely solved, and the cost of waste water treatment for enterprises is very high.

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.

Abstract

The invention provides a method for preparing healthy oil from platycarya strobilacea seeds. The method comprises steps as follows: the platycarya strobilacea seeds are ground, water is added, pH value of a feed liquid is regulated, amylase, acid protease and cellulase are added for enzymolysis, and oil and wastewater are obtained after centrifugation; the wastewater is adsorbed by 732 cation exchange resin, and effluent is obtained, used in next enzymolysis and oil extraction cycling steps and cycled 3-5 times for use; wastewater produced through cycling oil production and 2-3 times by weight of waste residues are taken as raw materials, water content is enabled to reach 30%-40%, 10%-20% by mass of bacillus subtilis powder is added, and aerobic fermentation culture is performed at 30-40 DEG C for 24-48 h. According to the method, protein content is reduced in an extraction process of platycarya strobilacea seed oil, so that an emulsification effect is obviously weakened, dissolving-out speed of phenols, tannin, saponin and other substances is reduced, water recycling is facilitated, and emission amount of the wastewater is reduced; due to the fact that the wastewater and the waste residues are directly used as the basis for producing fermented feed, risk of environmental pollution caused by the wastewater can be greatly reduced, and the use value of effective components in the wastewater is also improved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a comprehensive utilization method for preparing fenugreek seed oil from the seeds of the fenugreek tree, in particular to an aqueous enzymatic method for preparing the licorice tree seed oil and a method for cleaning and treating the waste water thereof. Background technique [0002] Huaxiang tree is an oil-bearing deciduous small tree. Mainly distributed in Gansu; Shaanxi; Henan; Shandong; Anhui; Jiangsu; Zhejiang; Jiangxi; Fujian; Taiwan; Guangdong; Guangxi; Hunan; Hubei; Sichuan; Guizhou; Yunnan. The tannin content of Huaxiang tree seeds is about 16.2-23.0%, and its oil content is as high as 26.5-35.7%. Promoting blood circulation, relieving pain, killing parasites and relieving itching. Indications for internal injury, chest and abdomen distension and pain, bruises, muscle and bone pain, carbuncle, eczema, scabies. [0003] Lemongrass leaves contain juglone, 5-hydro...
