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 fireworks absolute by a floating oil method and an application thereof, and belongs to the technical field of flavors and fragrances for tobacco. The method includes a series of processes of extraction, concentration, refrigerated stratification, secondary concentration, alcohol washing, three-time concentration, alcohol analysis, filtration, four-time concentration, and molecular distillation to prepare fireworks absolute, and prepare the fireworks absolute into a flavoring module , used in cigarettes. The present invention uses different concentrations of ethanol as the extractant and extraction agent, abandons the steps of membrane filtration and petroleum ether extraction in the traditional method, and uses the principle of oil-water separation to skillfully separate the oily substances and water-soluble substances in the fireworks extract, Macromolecular water-soluble substances such as sugars and proteins are removed, and the main aroma-causing components in fireworks are retained to the greatest extent. The method is simple, safe, economical, and has a high yield of net oil. After the obtained absolute oil is applied to the cigarette, the sweet and floral fragrance is obvious, the coordination is good, the burnt gas in the smoke is covered, 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...
