Detailed Description
The present application is further described with reference to the following figures and examples.
In the following description, the terms "first" and "second" are used for descriptive purposes only and are not intended to indicate or imply relative importance. The following description provides embodiments of the invention, which may be combined or substituted for various embodiments, and this application is therefore intended to cover all possible combinations of the same and/or different embodiments described. Thus, if one embodiment includes feature A, B, C and another embodiment includes feature B, D, then this application should also be considered to include an embodiment that includes one or more of all other possible combinations of A, B, C, D, even though this embodiment may not be explicitly recited in text below.
The following description provides examples, and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made in the function and arrangement of elements described without departing from the scope of the disclosure.

Furthermore, features described with respect to some examples may be combined into other examples.
At present, the cold stability of a wine sample is judged in the white spirit industry mainly by observing and determining the sample by experimenters, and the main operation steps are as follows: the method comprises the steps of placing a tested wine body in a sealed clean container (mainly made of transparent glass), freezing for 24 hours at-18 +/-2 ℃, observing whether phenomena such as turbidity and floccule precipitation exist to judge the cold stability of the wine body, and continuously wiping a bottle body to observe the clarification condition of the wine body by measuring the temperature by an experimenter during an experiment process, wherein the experimenter has large subjective factors and wastes time and labor.
Professional equipment for analyzing the cold stability of drinks such as white spirit and the like does not exist in the market at present; in the industry, turbidity and chromaticity of a sample (normal temperature) are mainly determined by using a nephelometer, a colorimeter and the like based on a spectrophotometric light absorption principle, so that the wine turbidity degree is determined, but when a low-temperature sample is determined by using the nephelometer or the colorimeter, the surface of a cuvette is easy to fog to cause measurement errors, and in addition, the temperature rise is fast due to the small amount of the sample, so that the equipment cannot track the temperature change in real time and cannot reflect the cold stability condition at a specific temperature.
The quality of the white spirit not only needs to reach the quality control standard except aroma, taste and the like, but also is expressed in the cold stability of the white spirit, if the bottled white spirit generates turbidity and flocculation precipitation at low temperature, the sensory quality of the white spirit is influenced, and the bottled white spirit is not accepted or misunderstood by consumers and is one of the expressions of poor quality control of manufacturers. The main reason for the turbidity of the white spirit is that when the temperature of higher fatty acid ester or fusel oil in the white spirit is reduced to about the refrigeration temperature, the solubility of the higher fatty acid ester or the fusel oil in ethanol is rapidly reduced, so that the white spirit is subjected to light loss and turbidity, white flocculent precipitates can be generated by coagulation after the white spirit is placed for a long time, the sense and the product quality of the white spirit are influenced to a great extent, and how to accurately analyze the cold stability becomes more important in the quality control of the white spirit.
