Carrot extract and application thereof in tobacco flavoring and charging

Abstract

The invention provides a carrot extract product which is produced by the following steps: pretreatment of fresh carrot, solvent extraction, filtration of extraction liquid and concentration of extraction liquid to obtain the carrot extract, wherein the dry carrot, carrot slurry, concentrated carrot juice or carrot residue obtained by the pretreatment step is extracted with an ethanol solution, and the extraction liquid is subjected to reduced-pressure concentration to obtain an extract product rich in carotenoids and soluble sugar and in a form of orange to red brown liquid or paste semi-fluid. The carrot extract is added into a tobacco product as perfume and can enhance the mellow aroma of tobacco and highlight the fresh and sweet aroma of tobacco while covering offensive odors, reducing irritation and improving taste; meanwhile, the tobacco color can be improved, and the tobacco mellowing is promoted. By adopting the method, the sugar and carotenoids in the carrot can be sufficiently extracted, the utilization rate of the raw materials is high, and the process is simple; without any harmful additive, the carrot extract product is safe to use.

Description

technical field [0001] The invention relates to the technical field of preparation of natural extracts for tobacco, in particular to a carrot extract, a preparation method thereof and an application in tobacco flavoring and addition. Background technique [0002] Extracts obtained from natural plants are one of the main flavoring materials for tobacco products, such as tobacco extracts, jujube extracts, raisin extracts, maple extracts, licorice extracts, fig extracts, and Luo Han Guo extracts. Extract, fenugreek extract, Peru extract, Tulu extract, plum extract, etc., have their own characteristics. Carrots are a common and extremely nutritious plant food rich in sugars and carotenoids, both of which play an important role in the aroma and appearance of tobacco. At present, the research on the use of carrot extracts is mainly focused on the extraction of carotene and special nutrients. The products are mainly used as food and nutritional health products, and there are only ...

Problems solved by technology

This method has high requirements on equipment and complicated process. The production process uses strong oxidant hydrogen peroxide and reducing agent sodium borohydride. The residue of any one of these two additives in the extract product is harmful to the human body, such as borohydride Sodium is highly irritating to the mucous membranes of the respiratory tract, eyes and skin, and can cause throat, bronchospasm, inflammation and edema after inhalation; and borate, the decomposition product of sodium borohydride in extract products, is also highly toxic, and is generally banned by countries all over the world Borate is added to food, and the relevant laws and regulations of our country also expressly prohibit the use of borate as a food additive, so the safety of the product of the inventive method needs to be improved

On the other hand, the sugar content in dried carrots is as high as 20% to 60%, and the inventive method cannot fully extract, and the utilization rate of carrots is relatively low.
