Embodiment 1

[0015] Macadamia nut shells were dried and crushed to obtain 50-mesh coarse powder, baked at a constant temperature of 25°C for 24 hours; the weight ratio of solvent to macadamia nut shells was 5:1, soaked in 95% ethanol solution overnight, and extracted by reflux for 17 hours. Filtrate while it is hot, and suction filter the filtrate with 300-mesh gauze until the filtrate is clear and transparent, and the temperature of the suction filtration is 35° C., and concentrate the suction filtration to an extract to obtain the macadamia nut shell extract of the present invention.

Embodiment 2

[0017] The macadamia nut shell was dried and crushed to obtain a 70-mesh coarse powder, baked at 80°C for 10 hours, cooled and soaked in 95% ethanol solution at a weight ratio of solvent to macadamia nut shell of 5:1 overnight, and extracted by reflux for 17 hours. Filtrate while it is hot, and use 300-mesh gauze to filter the filtrate until the filtrate is clear and transparent. The temperature of the suction filtration is 45° C., and the suction filtration is concentrated to an extract, and the macadamia nut shell extract of the present invention is obtained.

Embodiment 3

[0019] Macadamia nut shells were dried and crushed to obtain 100-mesh coarse powder, baked at 150°C for 5 hours, cooled and soaked in 95% ethanol solution at a weight ratio of solvent to macadamia nut shells of 5:1, and extracted by reflux for 17 hours. Filtrate while it is hot, and suction-filter the filtrate with 300-mesh gauze until the filtrate is clear and transparent, the temperature of the suction filtration is 60°C, and concentrate the suction-filtration until it is in the form of an extract, thereby obtaining the macadamia nut shell extract of the present invention.

Abstract

The invention relates to a macadamia shell extract and an application thereof, belonging to the technical field of natural plant processing and application. The macadamia shell extract in the invention can be obtained by the following steps: selectively grinding macadamia shell into 50-100 meshes, and baking for 5-24h on the constant temperature of 25-150 DEG C; extracting by 95% ethanol solution, wherein the weight ratio of the solution to the macadamia shell is 5:1, and refluxing for 17h on the condition of constant temperature; and filtering by a filtering method at the temperature of 35-60 DEG C, filtering until filtrate is clear and transparent by a 300-mesh cotton gauze, concentrating to be extractum to obtain the extract. The macadamia shell extract in the invention can be used as an additive to manufacture tobacco products. The invention has the beneficial effects that the macadamia shell extract can increase fragrance for tobacco products, endow tobaccos with unique note and opens up a new application filed for the macadamia shell extract.
