[0005] The Chinese invention patent application with the application publication number CN106996963A discloses a high-performance liquid chromatography separation and preparation method for the main chemical components of caprylic glyceride, specifically disclosing tricaprylic glyceryl, dicaprylic acid monocapric The separation method of the four main components of glyceryl caprylate, glyceryl monocaprylate and glyceryl tricaprate, the purity of each component obtained by separation is greater than 99%, but the separation of each component in glyceryl caprylate has not been realized. Quantitative determination of ingredients
[0006] The article "Determination of Three Kinds of Monoglyceride Contents in Bread by Gas Chromatography" published by Ma Yusong and others in the Journal of Analysis and Testing discloses the analysis methods for the content of glyceryl monocaprylate, glyceryl monocaprate and glyceryl monolaurate in bread. The standard solution was prepared with the standard substance of each analyte as the standard substance, but bread belongs to food, which is different from the interference in cigarette popcorn. The analysis method of the three monoglycerides in bread disclosed in the above article is not suitable for cigarettes. Quantitative detection of caprylic capric acid glyceride in popcorn

Abstract

The invention relates to a quantitative determination method for medium-chain triglycerides in a tobacco breakable bead solvent, and belongs to the field of tobacco additive component physical and chemical analysis. The quantitative determination method for medium-chain triglycerides in the tobacco breakable bead solvent comprises the following steps of carrying out mixing and extracting on crushed tobacco breakable beads, an extracting agent and an internal standard substance, and taking the supernate to carry out GC-FID measurement, and performing quantifying by an internal standard method,wherein the extracting agent is ethanol, acetone or dichloromethane. According to the method disclosed by the invention, the quantitative detection of the four components of the medium-chain triglycerides in the cigarette breakable bead solvent is realized for the first time, and the method has the advantages of being low in detection cost, rapid in detection, high in sensitivity and high in accuracy, and is suitable for quantitative detection of medium-chain triglycerides in the cigarette breakable beads and commercial medium-chain triglycerides.

Description

technical field [0001] The invention relates to a method for quantitatively determining caprylic acid glyceride in a cigarette popping bead solvent, and belongs to the field of physical and chemical analysis of cigarette additive components. Background technique [0002] Popping beads for cigarettes are a kind of beads that can be crushed. The inside of the popping beads contains a popping solvent and a fragrance substance. Through the sealed popping beads, the fragrance substance can be prevented from directly contacting the outside world, and the stability of the fragrance substance can be maintained. Popping beads are generally placed in the mouth stick of cigarettes. Consumers squeeze the popping beads to release flavor substances during the process of smoking the popping beads cigarettes, so as to achieve the effects of increasing flavor, moisturizing and reducing irritation. With the help of its own advantages, more and more similar products have poured into the market...
