Yellow peaches are generally mature and centralized on the market in 7-8 months per year, are not stored at normal temperature, have less than 2 months in fresh eating period, have low fresh-selling commodity fruit rate of the yellow peaches, have less than 10 percent of deep processing proportion, and are non-commodity fruits which do not reach the standard in weight, appearance and the like, are treated by fruit farmers at low price or directly discarded, so that great waste and environmental pollution are caused, and the processing of the yellow peaches becomes a necessary link for improving the industrial value of the yellow peaches. The current yellow peach processed products mainly comprise canned yellow peaches and dried yellow peaches. The yellow peach fruit wine is an ideal edible way and deep processing mode for yellow peaches, can reserve the original nutrient components in the yellow peaches to the maximum extent, and can meet the diversified demands of the fruit wine market.

Hanseniaspora (H.) is one of the leading wild Saccharomyces occurring in the early stage of natural fermentation of fruit wine, and is mainly selected from Hanseniaspora vinifera (H.vinae), Hanseniaspora viticola (H.uvarum), Hanseniaspora cactus (H.opuntiae), Hansenula montmorifolium (H.guilliermondii) and Hansenula osmansoni (H.osmophila). Compared with saccharomyces cerevisiae, the ethanol production capacity of h. fermentation is lower, which plays an important role in increasing volatile compounds of wine. Therefore, the invention provides the excellent Hanseng yeast with spores for the fermentation of the yellow peach fruit wine, and has important significance for improving the color, the aroma, the sense and the style of the yellow peach fruit wine.
Compared with the prior art, the invention has the advantages that:
(1) the invention provides a spore Hanseng yeast which can be applied to brewing yellow peach fruit wine and has the advantages of increasing the complexity of the aroma of the yellow peach fruit wine, improving the richness of the aroma, improving the quality of the yellow peach fruit wine and the like.
(2) The application of the Hanseng sporozoite yeast in the yellow peach fruit wine utilizes the Hanseng sporozoite yeast HT9 to be mixed with the saccharomyces cerevisiae for fermentation, can obviously improve the content of ester aroma substances such as ethyl acetate, phenethylacetate and the like, and thus effectively increases the aroma in the yellow peach fruit wine.

(3) The invention adopts the ozone composite high-voltage pulse electric field to degrade the pesticide residues, can effectively reduce the use concentration of ozone, simultaneously solves the problems that the pesticide residues are not completely reduced by the ozone and the degradation products with more toxicity are generated due to incomplete degradation at present, realizes the quick and effective degradation of the pesticide residues and ensures the food safety. Ozone is a strong oxidant, but is rarely applied in actual water treatment, mainly because of high economic cost, and how to reduce the ozone consumption and improve the utilization rate of ozone is a difficult point. The ozone composite high-voltage pulse electric field can generate a synergistic effect, the pulse discharge improves the solubility of ozone in water, the high-voltage pulse discharge and ozone oxidation fully utilize the liquid-electric cavitation effect generated by the high-voltage pulse discharge, the periodic expansion and contraction of bubbles between electrodes generate a large amount of fine bubbles, the contact area is increased to promote the ozone to enter a liquid phase or react at a gas-liquid interface in a large amount, the utilization efficiency of ozone oxidation is improved, and therefore, the ozone composite high-voltage pulse electric field has a good degradation effect on pesticide residues.
(4) The invention adopts low-frequency ultrasonic wave for auxiliary fermentation after yeast inoculation, can accelerate the utilization of yeast to substrate glucose by low-frequency ultrasonic wave, accelerates reproductive metabolism, quickly increases yeast value and iterates, and increases CO2The generation of the alcohol is reduced, and meanwhile, the influence of other flavor substances such as esters and acids is small; on the other hand, the content of pectin in the yellow peaches is high, the content of fusel alcohol such as 2-methyl-1-propanol, 2-methyl-1-butanol and 3-methyl-1-butanol after fermentation is generally high, and free radicals generated by low-frequency ultrasonic cavitation react with tartaric acid, ethanol, ferrous iron, copper ions, mannitol and the like, so that the generation of high-grade alcohol is reduced, and the improvement of the quality and the flavor of the fruit wine is facilitated.
(5) According to the invention, a small amount of sulfur dioxide, freezing and ultrasonic treatment are adopted to terminate fermentation after the main fermentation is finished, so that the stability of the quality of the yellow peach fruit wine in the later period is ensured. Because the yellow peach fruit wine has low alcohol content and high residual sugar content, microorganisms in the product are still in an active period, and the stability in the later period is difficult to ensure, the freezing treatment after fermentation can better inhibit the continuous activity of the microorganisms such as residual saccharomycetes and the like, is favorable for accelerating the sedimentation of pulp suspended substances in the wine, and increases the stability of the pulp suspended substances; the low-temperature treatment has small influence on flavor components and overall aroma quality of the wine body, is beneficial to keeping fresh and mellow taste and improving the sensory quality of the yellow peach fruit wine; meanwhile, the cavity effect and the high-energy micro bubbles generated by the ultrasonic treatment of 40 kHz-50 kHz can enable the wine body to be in a transient high-temperature and high-pressure state, accelerate the breaking of microbial cells such as yeast and the like, and better ensure the microbial stability of the product.
