Abstract

The invention relates to a qualitative analysis method for chemical compositions in white wine sediments, belonging to the field of food analysis and detection. The technical problem solved in the invention is to provide the qualitative analysis method for chemical compositions in white wine sediments. The method comprises the following steps: a, preliminary analysis: measuring ion contents in a wine sample before and after sedimentation and determining the elemental compositions in the sediments, and preliminarily determining the ionic compositions in the sediments by combining the variable data of ion content in the wine sample before and after sedimentation with the elemental compositions of the sediments; and b, determination analysis: using a compound structural analysis method to analyze the structure of compounds in the sediments, and combining the preliminary analysis result in step a to determine the chemical compositions in the sediments.

Description

technical field

[0001] The invention relates to a qualitative analysis method for chemical components in liquor sediment, belonging to the field of food analysis and detection. Background technique

[0002] Liquor produced by the solid-state method, after brewing, storage, blending, pulping, and packaging, sometimes tends to have problems such as turbidity, loss of gloss, and precipitation during the shelf life, which will affect product quality and corporate benefits. There are many reasons for the turbidity and precipitation of liquor. The shape of the precipitation is needle-like, flaky, powdery, flocculent or crystalline; the color is milky white, off-white, light yellow, yellow, reddish brown, blue-black, green, dark brown Wait. Reports in this regard are mostly speculative and lack scientific basis.

[0003] The qualitative analysis of the chemical components in the liquor sediment can confirm the chemical composition in the sediment, and the enterprise can take corr...

Embodiment Construction

[0020] The qualitative analysis method of chemical composition in liquor sediment of the present invention comprises the steps:

[0021] a. Preliminary analysis: measure the ion content in the wine sample before and after precipitation, and determine the elemental composition of the precipitate; combine the ion content change data of the wine sample before and after precipitation and the elemental composition of the precipitate to preliminarily confirm the ion content in the precipitate ion composition;

[0022] b. Confirmation analysis: use the compound structure analysis method to analyze the structure of the compound in the precipitate, and combine the preliminary analysis results of step a to confirm the chemical composition in the precipitate.

[0023] Further, in order to facilitate the initial confirmation of the ion composition in the sediment, the appearance of the liquor sediment is also analyzed during the preliminary analysis in step a, according to the color and s...
