Problems solved by technology

This method uses flash extraction and molecular distillation to obtain fireworks essential oil, but the flash extractor extracts a small amount of samples due to equipment reasons, which is only suitable for the analysis and testing of a small amount of samples and cannot be used in industrial production. The power used should not be too large, and the one-time use time is also strictly limited (no more than 2 minutes), and in terms of net oil yield, the "floating oil method" process of the present invention is also higher

Abstract

The invention relates to a method for preparing tobacco flower absolute by an oil floating method and an application thereof, belonging to the technical field of tobacco essence and flavor. The methodcomprises the following steps: extracting, concentrating, refrigerating and layering, secondary concentrating, ethanol washing, third concentrating, ethanol precipitating, filtering, fourth concentrating and molecular distillation to prepare the tobacco flower absolute, and preparing the tobacco flower absolute into a flavoring module for application in cigarettes. The invention takes ethanol with different concentrations as extracting agent and extractant, abandons membrane filtration and petroleum ether extraction of the traditional method, and uses the oil-water separation principle, cleverly separates the oily substances and water-soluble substances in tobacco flower extract, removes saccharides, proteins and other macromolecular water-soluble substances, retains the main aroma components in tobacco flower to the greatest extent, the method is simple, safe, economic, high yield of tobacco flower absolute. After the tobacco flower absolute is applied to cigarettes, the sweet flowerfragrance is obvious, the coordination is good, the scorched miscellaneous gas in the smoke is concealed, and the aftertaste is pure and natural.

Description

technical field [0001] The invention belongs to the technical field of flavors and fragrances for tobacco, and in particular relates to a method for preparing fireworks absolute by a floating oil method and an application thereof. Background technique [0002] Molecular distillation technology is a new type of liquid-liquid separation technology that has developed rapidly in recent years. Because it is especially suitable for the separation and purification of high boiling point, heat-sensitive and easily oxidized materials, and has the advantages of high vacuum and low separation temperature, it has been widely used in food and medicine. It has significant advantages in the separation of natural products in the fields of daily chemicals, spices, etc., and can better enrich the characteristic aroma components of natural products. However, when molecular distillation technology is used to separate natural products, in a high vacuum and high temperature environment, macromolec...
