Qualitative analysis method for chemical compositions in white wine sediments

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...

AI Technical Summary

Problems solved by technology

At present, there are many difficulties in the qualitative analysis of liquor sediments, the main difficulties are as follows: the conventional analysis method mainly analyzes the sediments directly, so a certain amount of sediments needs to be obtained before qualitative analysis can be performed, and the precipitation of liquor sediments The amount is relatively small, and the enrichment and separation of the precipitate are difficult, and the precipitate is prone to change during enrichment and separation

In addition, the current analysis methods cannot comprehensively analyze the chemical components in liquor sediments.
