Problems solved by technology

The determination of these indicators has its own focus. For example, the acid value is an important performance index of flavors. Generally speaking, the content of free acid in flavors is very small, but if the processing is improper or the storage time is too long, due to the decomposition and hydrolysis of flavor components, Or oxidation will increase the free acid content in it, and the quality of flavor will decrease.

Embodiment 1

[0013] Use surface tension as an index to evaluate the quality of Yunyan (soft treasure) sugar material:

[0014] 1. Determination of the surface tension value of the standard product: Prepare 10 qualified samples of Yunyan (soft treasure) sugar material produced at different times and in different batches for the determination of the standard surface tension. The determination steps and solution concentration preparation refer to the standard "GB / T 5549-2010 Surface active agent is measured by pulling up liquid film method to measure surface tension". The specific steps are: the measurement should be carried out in a constant temperature room, and the temperature of the test solution should be kept constant. The temperature can generally be in the range of (20-25) °C Choose one of them. When measuring, the measuring cup is first rinsed with the solution to be tested several times, and then the test portion is sucked into the measuring cup from the middle of a large amount of ...

Abstract

The invention discloses a method of evaluating the quality of tobacco essence and spice with surface tension as an index. The method includes the steps of respectively measuring the surface tension of a standard sample of the tobacco essence and spice and a sample to be tested, calculating relative deviation of the surface tension of the sample to be tested to the standard sample, if the absolute value of the relative deviation is not more than 10%, the sample to be tested is qualified, or otherwise, the sample to be tested is unqualified. Because the properties of the tobacco essence and spice will influence the surface tension of liquid, the properties of the tobacco essence and spice in a solution can be reflected in a certain degree by measuring the surface tension. Through calculation of the relative deviation of the surface tension of the sample to be tested to the standard sample, whether the tobacco essence and spice is qualified or not can be determined. With combination of a liquid-film pull-up method, the method is quick in identification and is high in accuracy and can be used as an effective quality evaluation and control index for the tobacco essence and spice.

Description

technical field [0001] The invention belongs to the technical field of quality control of cigarette flavors and fragrances, and in particular relates to a method for evaluating the quality of tobacco flavors and fragrances by using surface tension as an index. Background technique [0002] The role of cigarette additives is to improve the smoking quality of cigarettes and form the unique style of cigarette brands. On the one hand, cigarette additives can adjust the pH of the smoke, improve the taste and make the aftertaste comfortable; Addition can improve the physical properties of tobacco; in addition, cigarette addition can further balance the main chemical components on the basis of raw material formula, adjust the aroma of cigarettes and endow cigarette products with style. Therefore, the quality stability of cigarette flavor and fragrance must directly affect the quality stability of cigarette products. However, affected by various factors such as raw materials and p...
