Lactic acid refining extraction process and application thereof

Abstract

The invention relates to a lactic acid refining extraction process and application thereof, and belongs to the technical field of tobacco. The lactic acid refining extraction process comprises the following steps: S1, mixing lactic acid and water according to a certain mass ratio, adding the mixture into a rotary evaporator, carrying out rotary evaporation under the conditions that the first temperature is 75-85 DEG C and the first pressure is 215-225 mbar, and collecting a first rotary evaporation substance; and S2, after the rotary evaporation is completed, continuously carrying out rotary evaporation under the conditions that the second temperature is 90-105 DEG C and the second pressure is 15-25 mbar, and collecting a second rotary evaporation substance which is the refined lactic acid. The lactic acid refining extraction process is easy to operate, lactic acid with high purity can be effectively extracted, and after the refined lactic acid is added into cigarettes, the cigarettes are rich and full in fragrance, agglomeration and moist feeling are improved, the smoke state is good, irritation is avoided, and the taste is comfortable.

Description

technical field [0001] The application relates to a lactic acid refining extraction process and its application, belonging to the technical field of tobacco. Background technique [0002] In the cigarette industry, lactic acid can be used to remove impurities in tobacco, remove pungent taste, improve taste, and improve tobacco grade. Lactic acid in tobacco can significantly reduce the pH value of cigarette smoke, improve cohesion, and improve smoking taste. [0003] The lactic acid added in the cigarette in the prior art is purchased directly on the market mostly. The inventor has found through research that commercially available lactic acid contains more impurities (such as figure 1 As shown), adding commercially available lactic acid directly to cigarettes can improve the effect of cigarettes to a certain extent, but there are still problems such as increased smoke, reduced hot tingling, lack of hair penetration, tongue residue and acupuncture Significantly increased se...
