Description
Technical Field
The invention relates to white spirit catalysis Chen Lingyu, in particular to a method for catalyzing and ageing white spirit by electrochemical oxidation.
Background
The new wine just produced has pungency and can only be calculated as a semi-finished product. Similar to brandy and whiskey, white spirit generally needs to be stored for a certain time to be aged, so that the irritation and pungency of new wine are reduced, the wine body is soft and palatable, mellow and strong, and the taste is coordinated, and the phenomenon is called "aging" or "aging" in the white spirit industry. The ageing time is 3 to 5 years, even 10 years, and the long-time ageing greatly increases the brewing cost and the selling price of the white spirit. Therefore, the white spirit industry is in urgent need of a manual ageing accelerating technology, so that the white spirit ageing time is shortened.
In the prior art, an electrocatalytic method (publication number: CN 86103016C) for accelerating aging of wine is adopted to perform electrocatalytic by adopting a Pt-Pt electrode with catalytic activity, a reference electrode and a constant potential polarization power supply system so as to complete the aging accelerating process of the wine. However, by controlling the platinum potential of the working electrode of the oxidation and reduction groups, the catalytic effect is unstable, and the difference of the liquor samples processed in different batches is large, so that the stability of the quality of the white liquor is affected. Therefore, development of an electrocatalytic method for accelerating aging and curing of white spirit with stable catalytic effect is needed to ensure the quality and stability of white spirit.

Using the oxidation current of the self-assembled film as a judgment condition for the aging stop time: the reducing substance and the modified self-assembled film in the new wine can be oxidized to form a competition reaction, but the reducing substance has low oxidation potential and is oxidized first. When the self-assembled film starts to oxidize, the reducing substances in the new wine are obviously consumed, and the current generated at the moment when the self-assembled film starts to oxidize is greatly increased, so that the oxidation reaction is stopped, excessive oxidation of the new wine is avoided, excessive acid substances are generated, the ethyl caproate exceeds the standard, and the quality of the white wine is influenced.
Preferably, the self-assembly solution consists of a volume ratio of 2 to 10:100:200, ethanol and butanol.
Specifically, the polishing step is to sequentially polish the gold electrode into a mirror surface by using aluminum oxide polishing powder with the particle sizes of 0.2-0.4 microns and 0.04-0.06 microns, so that the polishing effect of the surface of the gold electrode is ensured.
Specifically, the surface of the gold electrode is cleaned by sequentially using 8-15% by volume of dilute hydrochloric acid aqueous solution, 40-60% by volume of ethanol aqueous solution and deionized water, so that the surface of the gold electrode is kept clean and then subjected to film forming reaction.
Specifically, after immersing in the self-assembly solution for reaction, cleaning the surface of the gold electrode, sequentially cleaning the surface of the self-assembly film by using an aqueous solution of 40-60% ethanol and deionized water in volume fraction, and cleaning the residual solution on the surface of the self-assembly film.
In the invention, the new wine testing step provides reducibility identification for new wines in different batches, provides guidance for setting oxidation voltage, and avoids insufficient or excessive aging. And an oxidation catalyst Chen Buzhou, which rapidly oxidizes the reducing substances in the new wine by utilizing the catalysis of the working electrode, so that the new wine is rapidly aged. And stopping the ageing, namely stopping the reaction according to the reaction current in time, so as to ensure the stability of the quality of the white spirit.
The invention has the advantages that the self-assembled film is adopted to modify the gold electrode as the working electrode, proper oxidation potential is selected to oxidize the new wine, and the aging is stopped under proper reaction current condition. On the premise of ensuring the quality stability of the white spirit, the aging time of the white spirit is shortened, and the method has important significance for promoting the sustainable development of the white spirit industry.
