Problems solved by technology

[0008] But the above prior art still has the following problems: 1, the bromelain activity in the pineapple fruit wine is high, and after the fermentation finishes, oral cavity and stomach are still irritated; The clarification time in the later stage is long and secondary precipitation is easy, and the pectin and protein of the pineapple are easy to form floc gel, and the clarification of the glue in the colloidal state is not thorough; 3. The content of methanol and fusel oil in the late stage of pineapple fermentation is high, and it is easy to get on the top

Abstract

The invention discloses a production method for making pineapple fruit wine. The method includes the steps: squeezing fresh pineapple fruits into juice, adding sulfur dioxide, adjusting pH (potentialof hydrogen) to reach 3.4-3.5 by the aid of tartaric acid, adding food-grade NaCl to adjust intensity of conductivity of the juice, preheating the juice to reach the temperature of 30-38 DEG C, keeping the temperature for 3-5 minutes, and pumping the juice in a high-strength electric pulse electric field treating chamber; placing the treated pineapple juice at the temperature of 0-4 DEG C, and taking liquid supernatant; adjusting pineapple sugar degree in the liquid supernatant; taking adjusted clarified pineapple juice, adding yeast, and fermenting mixture for 5-7 hours by controlling the temperature of 20-25 DEG C; adding activated bentonite into the pineapple fruit wine, standing at low temperature, taking liquid supernatant, enabling the liquid supernatant to pass a deep filter film and a sterilization filter film, and filling cans with the liquid supernatant to obtain the pineapple fruit wine. According to the method, by a high-strength electric pulse electric field treating mode,the tartaric acid and the NaCl are added, components of the pineapple juice are adjusted, pretreatment before fermentation is implemented, and the prepared pineapple fruit wine is unique in flavor, high in clarity degree and quality and low in fusel oil and methyl alcohol.

Description

technical field [0001] The invention relates to fruit wine, in particular to a production method for brewing pineapple fruit wine, and belongs to the technical field of fermented wine processing. Background technique [0002] Pineapple, formerly known as pineapple, belongs to the family Bromeliaceae, a tropical herb. Pineapple has a strong aroma, and the pineapple wine made from pineapple has a typical aroma, but the pineapple wine produced is prone to secondary precipitation. The turbidity in pineapple wine is mainly composed of protein, polyphenols, pectin and other mixtures. During the change of standing conditions, changes in polyphenols, protein, temperature, and light will cause unstable factors to the wine body, and the polymerization will form Insoluble complexes produce turbidity or precipitation. The clarifying agent is mainly used to remove the suspended protein and pectin macromolecules in the wine body during the clarification process of the wine. After the fe...
