Embodiment

[0025] A method for evaluating the sensory quality of hawthorn wine, using gas chromatography to determine the contents of three higher alcohols in hawthorn wine, comprising the following steps:

[0026] 1) Higher alcohol standard solution configuration: Weigh 0.5500g of isobutanol, isoamyl alcohol and phenylethyl alcohol in a 100mL volumetric flask respectively, and dilute to the volume with ethanol with a volume fraction of 30% to obtain a standard stock solution; then use a volume fraction of 30% % of ethanol and n-butyl acetate are used to carry out gradient dilution on the standard stock solution, and configure the standards with mass concentrations of 10mg / L, 30mg / L, 80mg / L, 120mg / L, 180mg / L, and 360mg / L respectively. solution, and the mass concentration of n-butyl acetate in the standard solution is 50mg / L;

[0027] 2) Sample configuration: Weigh 2mL of hawthorn wine, filter it through an inorganic water-based filter membrane with a pore size of 0.45 μm, dilute it, and ...

Abstract

The invention belongs to the technical field of food inspection and detection, and specifically discloses a sensory quality evaluation method of hawthorn wine. The sensory quality evaluation method of the present invention uses gas chromatography to measure the contents of three higher alcohols in hawthorn wine, comprising the following steps: 1) preparation of higher alcohol standard solutions: using ethanol and n-butyl acetate to configure isobutanol, isoamyl alcohol and phenylethyl alcohol 2) sample preparation: dilute the hawthorn wine and add n-butyl acetate to prepare a sample solution; 3) adopt gas chromatography to detect the standard solution and the sample solution and calculate the content of higher alcohols in the sample solution; 4 ) Sensory quality judging conditions: judge the sensory quality of hawthorn wine according to certain judging conditions. The sensory quality evaluation of the present invention can objectively and accurately judge the sensory quality of the hawthorn wine by measuring the content of the main flavor substance higher alcohol of the hawthorn wine, and according to the content relationship among the higher alcohols.

Description

【Technical field】 [0001] The invention relates to the technical field of food inspection and detection, in particular to a method for evaluating the sensory quality of hawthorn wine. 【Background technique】 [0002] Hawthorn, also known as Shanliguo and Shanlihong, belongs to the Rosaceae Hawthorn genus. Hawthorn fruit contains a variety of nutrients and is a well-known medicinal and edible fruit. Hawthorn wine is brewed with hawthorn fruit as the main raw material through a fermentation process. The wine is mild and refreshing, with a strong fruity aroma. It basically maintains the nutrients in the hawthorn fruit. It is a natural and healthy biological drink. [0003] At present, the basic method of sensory quality evaluation of hawthorn wine is that sommeliers taste hawthorn wine to obtain the sensory quality evaluation results of hawthorn wine. However, this method is greatly affected by personal subjective factors, and the evaluation results are unstable. 【Content of in...
