experiment example 1

[0028] Experimental Example 1 Effect of Pectinase Addition Amount on Juice Yield

[0029] Select fresh, ripe Kyoho grapes with consistent color and a sugar content above 17°Bx to remove rotten and moldy fruits. Weigh 5 parts of Kyoho grapes, 500g each, break into grape pulp, add 0, 0.04mL / kg, 0.08mL / kg, 0.12mL / kg and 0.16mL / kg pectinase to hydrolyze for 30min, and detect the juice yield. The result is as figure 1 shown. When the amount of pectinase added is 0-0.12mL / kg, the juice yield has an obvious increasing trend. When the amount of pectinase added is 0.08mL / kg and 0.16mL / k, the grape juice yield is higher, 76% and 79%. %, the juice yield was the highest when the addition amount was 0.12mL / kg, reaching 80%. Therefore, the addition amount of pectinase is preferably 0.08-0.16mL / kg.

[0030] Experimental Example 2 Effect of Addition of Potassium Metabisulfite on Wine Fermentation

[0031] (1) Sorting: Select fresh, ripe Kyoho grapes with consistent chroma and sugar content above 17°Bx, and remove rotten and moldy fruits. Weigh 5 parts respectively, each 500g.

[0032] (2) Crushing: Soak the sorted Kyoho grapes in water to remove dust respectively, dry them naturally, remove grape stems and grape seeds, crush pulp and pericarp, and obtain grape pulp mixed with pomace.

[0033] (3) Dipping fermentation: 0, 10 mg / kg, 30 mg / kg, 50 mg / kg and 70 mg / kg of potassium metabisulfite were added to 5 portions of grape pulp respectively, and allowed to stand for 2 hours. Add 0.12mL / kg pectinase, and enzymatically hydrolyze for 30min. Add sucrose to bring the initial brix of the grape syrup to 26°Bx. Add 0.02% wine active dry yeast RW, mix well, soak and ferment in a constant temperature incubator at 24° C. for 10 days to obtain preliminary fermented wine.

[0049] (1) Sorting: Select fresh, ripe Kyoho grapes with consistent chroma and sugar content above 17°Bx, and remove rotten and moldy fruits. Weigh 5 parts respectively, each 500g.

[0050] (2) Crushing: Soak the sorted Kyoho grapes in water to remove dust respectively, dry them naturally, remove grape stems and grape seeds, crush pulp and pericarp, and obtain grape pulp mixed with pomace.

[0051] (3) Dipping fermentation: Add 30 mg / kg of potassium metabisulfite to 5 portions of grape juice respectively, and let stand for 2 hours. Add 0.12mL / kg pectinase, and enzymatically hydrolyze for 30min. Add sucrose again, make the initial brix of grape syrup reach 26 ° Bx. Then add 0, 0.01%, 0.02%, 0.03% and 0.04% wine active dry yeast RW respectively, mix well, soak and ferment for 10 days in a constant temperature incubator at 24°C to obtain preliminary fermented wine.

Abstract

The invention discloses a pink kyoho grape wine, which is prepared by following steps: choosing matured kyoho grapes with a sugar degree more than 17 degree Bx; grinding kyoho grapes to obtain grape pulp; adding potassium metabisulfite (10-50 mg / kg), allowing the system to stand still for 0.5 to 2 hours; adding pectase (0.08-0.16 mL / kg), carrying out enzymatic hydrolysis for 5 to 30 minutes; adding cane sugar and wine active dry yeast RW (0.01-0.03%), evenly mixing, carrying out impregnation and fermentation for 10 to 15 days in a thermostatic incubator with a temperature of 22 to 26 DEG C, filtering, separating, sealing, placing the wine in a refrigeration house with a temperature of 10 to 16 DEG C, and carrying out brewing for 10 to 28 days in the absence of light to obtain the pink kyoho grape wine. The invention also discloses a brewing technology of the pink kyoho grape wine. The prepared pink kyoho grape wine has a bright color, a tender taste, and fresh aroma. The resource wastedue to poor market and storage is reduced, the benefits of farmers are protected, and the kyoho grape industry is promoted.

Description

technical field [0001] The invention relates to pink wine and its brewing process, in particular to Kyoho pink wine and its brewing process. Background technique [0002] Kyoho grape (Vitis vinifera cv. Kyoho) is originally produced in Japan. Due to its strong adaptability, disease resistance and cold resistance, after being introduced into China, it has been widely promoted all over the country and has become one of the main grape varieties in my country. . Kyoho grapes ripen in late August. When ripe, they are purple-black with basically the same color. The fruit is uniform in size and weighs 10-14g. It has a lot of powder and soft flesh. Kyoho grapes not only have edible value, but also have certain medicinal value. They have the effect of adjuvant treatment for hypotension, and the anti-cancer trace element resveratrol contained in it has the highest content among all quality grapes. [0003] As one of the main varieties of grapes in my country, Kyoho grape has a wide p...
