Problems solved by technology

[0005] Both CN104686979B and CN201110280315.2 mention the use of macroporous resins to remove impurities and detoxify the smoked liquid. However, the removal effect of toxic and harmful substances in it is very small, and multiple adsorption treatments are required. Not only the cost is high, but the aroma substances The loss is also more serious
The method is complicated, the activated carbon cannot be reused, the cost is high, and the adsorption of activated carbon is extensive, there is no distinction between aroma components and toxic components, and the product quality is not easy to control

Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0028] The invention provides a rubber wood essence and a preparation method thereof. Freshly felled rubber wood with an age of 7 years is selected, the fresh wood is broken so that its equivalent diameter is controlled at 3-4 cm, and the wood fragments are subjected to nitrogen blasting treatment , the temperature was controlled at 60 °C, the pressure was 100 MPa, the pressure was maintained for 4 min, and the blasting treatment was repeated once. Then, the wood blocks after nitrogen blasting were added with laccase, the mass fraction of laccase was 0.5%, and the temperature was kept at 60 °C. Heat preservation fo...

Abstract

The invention discloses a rubberwood essence and a preparation method thereof. The preparation method includes the following steps: crushing rubber wood (5-10 years old), the equivalent diameter is controlled at 2-5cm, the crushed wood block is subjected to nitrogen blasting treatment (50-300MPa), and the wood block after the nitrogen blasting is added with paint Enzyme (0.1-3%), the wood blocks treated with laccase are dried to a moisture content of 8-25%, the dried cork fragments are mixed with a flame retardant, placed in an environmentally friendly drying furnace, and gradient heating and Endogenous smoke technology, the temperature of the combustion kettle is controlled at 150-200 ℃, flameless and anoxic combustion. The cork essence is obtained by gradient fractionation, tertiary purification, cooling and collection. The product obtained by the invention has a strong fragrance, does not contain harmful substances such as benzopyrene, and can be used as an additive to develop smoked food, feed, medicine or other industrial products.

Description

technical field [0001] The invention relates to a rubber wood essence and a preparation method thereof, belonging to the field of food processing, and specifically refers to taking 5-10-year-old rubber cork as a raw material, after crushing, nitrogen blasting and laccase treatment, drying and mixing with resistance After the fuel is mixed, it is placed in an environmentally friendly drying furnace, using gradient heating and endogenous smoke technology, the temperature of the combustion kettle is controlled at 150-200 ° C, and the flameless and anoxic combustion is carried out. Cork essential oil is subjected to gradient fractionation, tertiary purification, cooling and collection to obtain cork essence. The product obtained by the invention has rich aroma, unique smoky taste, and does not contain harmful substances such as benzopyrene and dioxin. Background technique [0002] Smoking is a common and time-honored food processing technique traditionally used to prolong the s...
