Embodiment 1

[0021] A preparation method of the extract of Gardenia jasminoides:

[0022] 1) Put the gardenia fruit into an extraction tank after being crushed, add water with a mass ratio of 1:20, and add lactic acid bacteria and compound enzymes in an amount of 0.3% of the gardenia fruit mass, stir evenly, and dissolve at 45°C and pH Under natural conditions, ferment for 3 hours to obtain a gardenia fermented liquid;

[0023] Described lactic acid bacteria and compound enzyme are: account for 0.3% of gardenia fruit quality altogether, wherein lactic acid bacteria freeze-dried bacteria powder (food grade) accounts for 0.15%, β-glucosidase (food grade, enzyme activity is 1000u / g) accounts for 0.075% %, neutral protease (food grade, enzyme activity 50,000 u / g) accounts for 0.075%;

[0024] 2) Alcohol precipitation and purification: add 15% ethanol (95%, food grade) of water volume to the gardenia fruit fermentation broth, extract 3 times at low temperature and pressure, filter with suction...

Abstract

The invention discloses a preparation method for a fructus gardeniae extract for tobacco. The preparation method is characterized by comprising the following steps: (1) crushing fructus gardeniae fruits, adding the crushed fructus gardeniae fruits into an extracting tank, adding water, and adding lactobacilli and complex enzyme for fermenting to obtain fructus gardeniae fruit fermentation liquid, wherein the fructus gardeniae fruit and the water are in the mass ratio of 1 : (20 to 40); (2) performing alcohol precipitation and purification on the fructus gardeniae fruit fermentation liquid to obtain secondary fructus gardeniae concentrated liquid; (3) performing molecular distillation refining, namely, performing vacuum concentrating on the secondary fructus gardeniae concentrated liquid to obtain tertiary fructus gardeniae concentrated liquid, adding propylene glycol, performing further separation and purification on the tertiary fructus gardeniae concentrated liquid in molecule distillation equipment, collecting a light component, performing molecular distillation purifying on a heavy component again, and combining two light components to obtain the fructus gardeniae extract for the tobacco. According to the preparation method, the fructus gardeniae extract for the tobacco is prepared by adopting compound fermenting, solvent low-temperature extracting and molecular distillation refining, and is applied to reconstituted tobacco, so that the appearance colour and lustre of the reconstituted tobacco are more natural and uniform, and are close to those of high-quality tobacco; the pH value of smoke is reduced; aroma is enriched; stimulation and miscellaneous gas are reduced; the smoking taste is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco additives, in particular to a preparation method and application of a gardenia tobacco extract. Background technique [0002] Reconstituted tobacco leaves are mainly composed of tobacco powder, chips, tobacco stems or low-grade tobacco leaves with adhesives and other additives. However, there are also taste defects such as heavy miscellaneous gas, strong irritation and unpleasant taste, which affect the use effect and addition amount of reconstituted tobacco leaves in cigarette products. The usual practice in China is to use additives to improve. At present, the most used additives are tobacco and natural plant extracts. These extracts are generally obtained through water, alcohol extraction or molecular distillation. The degree of improvement in cigarette quality after adding Limited, there are still defects such as large irritation and a lot of miscellaneous gas. [0003] Gardenia (scientific ...
