Description

A kind of preparation method of longan liquor
Technical field
The present invention relates to a kind of preparation method of liquor, relate to a kind of preparation method of longan liquor specifically.
Background technology
Longan is the precious fruit variety of Subtropic of China.In recent years, Longan Cultivation area continuous enlargement.The longan ripening stage is in high temperature season, and longan fresh fruit not shelf-stable, transports for long-distance perishable, and traditional processed goods of longan is dried longan, and kind is single, and market is limited, the sale problem of outlet that unresolved Longan Output increases.Longan pulp, containing sugars such as glucose, fructose, sucrose, up to about 20%, is the high quality raw material of brewed fruit wine.But the fragrance of longan fermented wine is more weak, fail to brewage into high-quality high-grade dry wine.Like the angle of drinking white wine from China human consumer, start to develop longan liquor.Whether succeeding in developing of longan liquor, is how the flavor taste of mainly longan liquor is adapted to the key point that human consumer is Technology preparation tackling key problem.
Summary of the invention
The present invention, by studying domestic white wine for many years, develops a kind of preparation method of longan liquor.Improve from making method, reduce fermenting process and produce harmful as tunnings such as higher alcoholss.Novel process is prepared and longan liquor mouthfeel has longan is given off a strong fragrance, similar brandy flavor, drinks that back is not ached, mouth is not done, reduce widely drunk may with improve the entertaining drunk.Meeting the modern times drinks consumption and the theory of environment protection health, and longan liquor is applicable to the social life of modern high end stratum fashionable life, provides high-grade material, spiritual enjoyment with high-quality, high value for epoch elite and successful personage.The high-grade longan liquor of Study and Development, improves Business Economic Benefit and has realistic meaning and application prospect.
Longan fresh fruit is squeezed the juice through stripping longan aril, making beating, is added pectinase treatment and become longan fruit drink; Longan fresh fruit becomes longan dry fruit through roasting, become soak solution to add 55Brix sucrose syrup through stripping longan biltong, boiling water immersion treatment is prepared into dried longan fruit syrup.Longan fruit drink and dried longan fruit syrup adjust component and become longan liquor fermented liquid, add the high temperature resistant Active Dry Yeast in Angel and plant lactobacillus liquid to carry out first time and ferment, ferment after 2 days, add dried longan fruit syrup and carry out fed-batch fermentation and become longan liquor maturing fermentation wine with dregs; Lactobacillus delbruckii adds the lactic fermentation of dried longan fruit syrup and becomes lactic fermentation wine with dregs; Longan liquor karusen and lactic fermentation wine with dregs wine with dregs carry out being distilled into the former wine of longan, blend into the longan liquor of different class through ageing.
Adopt technical scheme as follows for realizing object of the present invention:
