Problems solved by technology

The market is more willing to use the water enzymatic method to extract the products obtained from the technology of black tiger seed oil. There is no risk in eating, and the quality of black tiger seed oil is higher
However, a large amount of industrial wastewater will be produced in the process of enzymatically producing black tiger seed oil. Since the wastewater contains a large amount of saponins and other antibacterial substances, traditional wastewater treatment methods cannot completely solve the problem, and the cost of wastewater treatment for enterprises is very high.

Embodiment 1

[0040] Weigh 100kg of black tiger 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, and stir evenly to obtain a feed solution; oxidize with 0.5mol / L hydrochloric acid or 0.5mol / L hydrogen Sodium aqueous solution was used to adjust the pH of the feed solution to 6, and amylase and cellulase were added to a final concentration of about 90U / L, and the enzymatic hydrolysis was performed for 4 hours. Add temperature-sensitive acid protease (rapidly inactivated above 45°C) to the enzymolysis material again to a final concentration of 100U / L, enzymolysis for 3 hours, and keep warm at 55°C for 35 minutes to obtain material solution I. Centrifuge the material liquid I on a decanter centrifuge to obtain liquid and wet residue, and the liquid directly enters the disc separator to separate black tiger seed oil and waste water I. The obtained black tiger seed oil is dried under vacuum condition, left to stand and t...

Embodiment 2

[0042] Weigh 200kg of black tiger seeds, grind them three times on a common grinder, add 1500L of effluent liquid I, heat to about 30-40°C, stir well to obtain feed liquid II; oxidize with 0.5moL / L hydrochloric acid or 0.5moL / L hydrogen Sodium aqueous solution was used to adjust the pH of the feed solution to 5.5, and amylase and cellulase were added to a final concentration of 75U / L, respectively, and the enzymatic hydrolysis was carried out for 3 hours. Add temperature-sensitive acid protease (rapidly inactivated above 45°C) to the enzymatic hydrolysis solution I again to a final concentration of 110 U / L, enzymatic hydrolysis for 3 hours, and keep warm at 55°C for 35 minutes to obtain feed solution III. Centrifuge the material liquid III on a decanter centrifuge to obtain liquid and wet residue, and the liquid directly enters the disc separator to separate black tiger seed oil and waste water II. The obtained black tiger seed oil is dried under vacuum condition, left to stan...

Embodiment 3

[0044] Take 500kg of waste water (without resin treatment) produced by recycling oil production as raw material, add 75kg of Bacillus subtilis powder (15%), cultivate at 37°C for 24h, and directly use it in refrigeration at 0~5°C as a feed starter. The total amino acid content was determined to be 105mg / g, and the protease activity reached 1340U / g.

Abstract

The invention provides a method for efficiently preparing oil by using kadsura coccinea seeds. The method comprises the steps of grinding seed kernels; adding water and adjusting the pH value of slurry; adding a mixed enzyme for enzymolysis and centrifuging to obtain seed oil and wastewater; carrying out adsorption treatment on the wastewater through 732 cation exchange resin and recycling the wastewater for multiple times; and adopting the wastewater produced by circulating oil preparation as a feed additive after fermentation treatment. According to the method, the emulsification effect is obviously weakened, the content of phenol and saponin in the water and the oil is obviously reduced, cyclic reuse of the water is facilitated and the discharge amount of the waste is reduced. A feed leavening agent is produced by adopting the wastewater as a basis, so that the risk that the wastes pollute the environment can be greatly reduced, and meanwhile, the utilization value of effective components in the wastes is also improved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a method for preparing black tiger seed oil from black tiger seeds, in particular to an aqueous enzymatic method for preparing black tiger seed oil and its waste recycling method. Background technique [0002] The black tiger is also called Mountain Breeze, Wind Sand Vine, Earth-Drilling Wind, Penetrating Earth Lianzhu, Three Hundred Taels of Silver, Red Diamond, Eighteen Symptoms, Ground Musk, Midorro, Big Diamond, Orangutan Schisandra, Drilling Bone Wind, Hongxiao, Guoshanxiang, and Schisandra chinensis are evergreen climbing vines, 3-6m long. The lower part of the stem is stuck in the soil, the upper part is twined, the branches are cylindrical, brown-black, with sparse white punctate lenticels. Single leaves alternate; stalk length 1-2.5cm; leaf leathery, leaf blade oblong to ovate-lanceolate, 8-17cm long, 3-8cm wide, apex obtuse or acute, base broadly cuneate or nearl...
