Embodiment 1

[0012] 100kg of fresh loquat fruit is cleaned and cored, soaked with 2mg / l sodium bisulfite aqueous solution to protect the color, adding 8g of sulfur dioxide or 20g of ascorbic acid to the fresh loquat pulp for pulping; use 15g of refined fruit pulp Gelase was treated at 30°C for 4 hours, then squeezed to separate and remove slag to obtain fruit juice; adjust sugar and acid to make the total sugar of the fruit juice reach 170g / l, and the pH value was 3.5-4.0, adding 1kg of expanded cultured yeast No. 1450 Alcoholic fermentation is carried out on the wine mother, and 50g / l sugar is added on the fourth day of fermentation. After 8 days, the wine is separated and transferred to the post-fermentation process. Blend the wine into semi-dry, semi-sweet, sweet and other types according to needs, add 80mg / L bentonite to the blended fruit wine for glue treatment, filter, sterilize, bottle, cork and seal after the wine body is clarified and stable Can.

Abstract

The present invention relates to loquat wine brewing technology and a technology of brewing and storing loquat wine without oxidation color change. The loquat wine is prepared with loquat fruit and through color protection, enzyme treatment, alcohol fermentation, stabilizing treatment and other steps. The pectase enzymolysis and liquefying treatment techonlogy used raises the loquat juice yield, facilitates the juice squeezing, prevents browning and deterioration during brewage. Some bacteria strain suitable for fermentation of loquat fruit is screened. The loquat wine has special loquat flavor, mild taste, mellow scent and stable quality.
