Problems solved by technology

However, if the tobacco flavor formula contains raw materials such as natural flavors, extracts or syrups, since these raw materials are a mixture of multiple components, the content of the components is different, the chemical properties of the substances are also different, and different components have different activities. There will often be chemical reactions or biochemical reactions in contact with microorganisms, resulting in the phenomenon of obvious differences in aroma and aroma before and after storage for a period of time

Embodiment 1

[0024] Take 200g of tobacco flavor product samples, store them at a freezing temperature of -4°C and a humidity of 60% for 42 hours, then transfer the samples to room temperature at Place it at a humidity of 90% for 42 hours, then transfer the product to a temperature of 98°C and a humidity of 20% for 42 hours. Determination of product acid value, volatility, refraction, density. The above steps are cycled once as a cycle, and the parameters are measured once in each cycle, so that 12 cycles are cycled, and all data are compared with standard samples. The comparison results are as follows:

[0025]

[0026]

[0027] Judgment of stability: From the test results of the above-mentioned product control indicators, it can be seen that the performance of the tobacco flavor product is stable, and after 12 cycles, the test results of various parameters are not significantly different from the initial values, and it is judged that there is no deterioration. Therefore, it is pre...

Abstract

The invention relates to a method for evaluating essence and flavor, in particular to a method for measuring stability of a flavoring essence and predicting quality guarantee period. The method comprises the following steps of: placing a flavoring essence sample under freezing environment, room temperature environment, high temperature and high humidity environment and high temperature drying environment for certain time in turn to measure parameters of an obtained product; circulating for several times in the same way; and comparing the parameters with those of a standard sample to acquire stability data of the flavoring essence and an estimated quality guarantee period value. The method of the invention has the advantages of scientificity, operability and high repeatability. The used instrument and facility are simple.

Description

【Technical field】 [0001] The invention relates to flavor evaluation testing technology, in particular to a method for measuring the stability of tobacco flavor and predicting its shelf life. 【Background technique】 [0002] The evaluation of the stability of spices and flavors mainly depends on two aspects: the stability of flavor or aroma, that is, whether the aroma or flavor of spices and flavors can remain unchanged to a certain extent after being stored for a certain period of time and under certain conditions; Whether spices and essences can maintain stable physical and chemical properties in their medium (or matrix), especially after a certain period of storage, and whether there will be quality changes after exposure to heat, light or air during storage. [0003] The main active ingredients of tobacco flavors include synthetic flavors and natural flavors. Under normal circumstances, for tobacco flavors compounded only from synthetic flavors, most of their aromas can b...
