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 object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The invention provides a rubber wood essence and a preparation method thereof. Freshly felled rubber wood with a tree age of 7 years is selected, and the fresh wood is crushed 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 100MPa, and the pressure was maintained for 4min. The blasting treatment was repeated once. Then, the wood block after the nitrogen blasting treatment was added with laccase. The mass fraction of laccase was 0.5%, and the temperature was maintained at 60°C. Keep ...

Abstract

The invention discloses rubber wood essence and a preparation method thereof. The preparation method comprises the following steps that rubber wood (the tree age is 5-10 years) is crushed, the equivalent diameter is controlled to be 2-5 cm, the crushed wood blocks are subjected to nitrogen explosion treatment (50-300 MPa), laccase (0.1%-3%) is added into the wood blocks subjected to nitrogen explosion, the wood blocks subjected to laccase treatment are dried till the moisture content is 8-25%, the dried soft wood fragments and a flame retardant are mixed and placed in an environment-friendly drying furnace, the gradient heating and internal smoke generating technology is adopted, the temperature of a combustion kettle is controlled to be 150-200 DEG C, and flameless oxygen-deficient combustion is achieved. Gradient fractionation, three-stage purification, cooling and collection are performed on the cork essence to obtain the rubber wood essence. The product obtained by the invention has strong fragrance, does not contain harmful substances such as benzopyrene and the like, and can be used as an additive to develop smoked foods, feeds, medicines 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, specifically refers to using 5-10-year-old rubber cork as a raw material, after crushing, nitrogen blasting and laccase treatment, drying and mixing with retarder After the fuel is mixed, it is placed in an environmentally friendly drying furnace, using gradient heating and internal smoke technology, the temperature of the combustion kettle is controlled at 150-200 ° C, and there is no flame and anoxic combustion. Cork essential oil undergoes gradient fractionation, three-stage purification, cooling, and collection to obtain cork essence. The product obtained by the invention has rich aroma, unique smoke flavor, and does not contain harmful substances such as benzopyrene and dioxin. Background technique [0002] Smoking is a common and long-established food processing technology. According to tradition, smoking is mainly used to ...
