Embodiment 1

[0047] Weigh 100kg of Litsea Cubeba, grind 3 times on an ordinary grinder, add to 300L of warm water with a water temperature of 35°C, and stir evenly to obtain a feed solution; use 0.5mol / L hydrochloric acid aqueous solution to adjust the pH of the feed solution to 6, add amylase and cellulase to a final concentration of 90U / L, hydrolyze for 3 hours, then add acid protease that is rapidly inactivated above 45°C to the hydrolyzate to a final concentration of 85U / L, hydrolyze for 3 hours, Keep warm 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 litsea cubeba oil and waste water I. The obtained litsea cubeba oil is dried under vacuum condition, left standing and then filtered to obtain the finished litsea cubeba oil, and the finished oil is inspected. Wastewater I is adsorbed by 732 cation exchange resin to obtain effluent I. After...

Embodiment 2

[0049]Weigh 200kg of litsea cubeba, grind it three times on a common grinder, add 1000L of effluent liquid I, heat to about 30-40°C, and stir well to obtain feed liquid II; use 0.5mol / L hydrochloric acid aqueous solution to adjust the pH of feed liquid II to 5.5 , add amylase and cellulase respectively to a final concentration of 85U / L, and perform enzymatic hydrolysis for 4 hours to obtain enzymatic hydrolysis solution Ⅰ. Add acid protease that is rapidly inactivated above 45°C to the enzymatic hydrolysis solution I again to a final concentration of 110U / L, hydrolyze for 3 hours, and keep warm at 55°C for 30 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 litsea cubeba oil and waste water II. The obtained litsea cubeba oil is dried under vacuum condition, left standing and then filtered to obtain the finished litsea cubeba oil, and t...

Embodiment 3

[0051] Take 100kg of waste water produced by circulating oil production as raw material, add 350kg of wet residue to make the water content reach about 30%, sterilize at 115°C for 20 minutes, then add 605kg of Bacillus subtilis powder, ferment at 28°C for 3 days, and granulate at 40°C Low temperature drying to obtain feed additives.

Abstract

The invention provides a method for producing litsea cubeba oil by utilizing litsea cubeba. The method comprises the following steps: grinding litsea cubeba, mixing the ground litsea cubeba and water, adjusting a pH value of a material solution, adding mixed enzyme, performing the enzymolysis, and centrifuging to obtain olive oil and waste water; adsorbing the waste water by virtue of a 732-cation exchange resin, and recycling for multiple times; adding wet residues into waste water produced by the circular oil production, enabling the water content to reach 25 to 35 percent, sterilizing for 20 to 30 min at the high temperature of 115 to 121 DEG C, adding 10 to 20 percent of bacillus subtilis powder, fermenting for 3 to 5 days at 25 to 30 DEG C, granulating, drying at a low temperature of 35 to 45 DEG C, and obtaining a feed additive. The content of proteins is reduced in the litsea cubeba oil extraction process, the emulsification effect is apparently weakened, the repeated application of the water is facilitated, and the discharging amount of the waste water is reduced. The waste water and the wet residue are directly utilized as a base to produce a feed product, so that the risk that the environment is polluted by the waste water can be greatly reduced, and the utilization value of active ingredients in the litsea cubeba can also be increased.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a method for preparing litsea cubeba oil from litsea cubeba, in particular to a method for preparing litsea cubeba oil and fully utilizing its waste. Background technique [0002] Although the output of litsea cubeba products in China is high, the overall production level is low, and the export is mainly primary crude oil. The current situation of litsea cubeba oil utilization, the main way of low-value export can no longer realize China's resource utilization advantages, which is high cost and low cost. The workshop mode of the output. Because Litsea Cubeba contains high aldehyde, it is easy to oxidize into acid or mildew and deteriorate when exposed to heat, moisture and humid air. It requires local purchase and processing, so the crude oil containing about 65% citral has been extracted by local distillation. , and then concentrated to the natural fragrance factory, dist...
