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 specifically a kind of preparation method of longan liquor.
Background technology
Longan is the precious fruit variety of Subtropic of China.In recent years, Longan Cultivation area continues to expand.The longan ripening stage, the not resistance to storage of longan fresh fruit, transported for long-distance perishable in high temperature season, 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 20% left and right, is the high quality raw material of brewed fruit wine.But, the fragrance of longan fermented wine a little less than, fail to brewage into high-quality high-grade dry wine.The angle of liking drinking white wine from China human consumer, starts to develop longan liquor.Whether succeeding in developing of longan liquor, is it is mainly how the flavor taste of longan liquor is adapted to the key point that human consumer is Technology preparation tackling key problem.
Summary of the invention
The present invention to domestic white wine research, develops a kind of preparation method of longan liquor by for many years.Improve from making method, reduce fermenting process and produce harmful as tunnings such as higher alcoholss.Novel process is prepared and in longan liquor mouthfeel, is had longan and give off a strong fragrance, and similar brandy flavor drinks that does not ache back, mouth is dry, reduces widely the drunk entertaining that may drink with raising.Meet drink consumption and the theory of environment protection health of modern times, longan liquor is applicable to the social life of modern high end stratum fashionable life, taking high-quality, high value as epoch elite and successful personage high-grade material, spiritual enjoyment are provided.Develop and develop high-grade longan liquor, improve Business Economic Benefit and there is realistic meaning and application prospect.
Longan fresh fruit is squeezed the juice, is added polygalacturonase and be processed into longan fruit drink through stripping longan aril, making beating; Longan fresh fruit becomes longan dry fruit, becomes soak solution to add 55Brix sucrose syrup through stripping longan biltong, boiling water immersion treatment to be prepared into dried longan fruit syrup through roasting.Longan fruit drink is adjusted component with dried longan fruit syrup and is become longan liquor fermented liquid, add the high temperature resistant Active Dry Yeast in Angel and plant lactobacillus liquid to ferment for the first time, ferment after 2 days, add dried longan fruit syrup to 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 to become lactic fermentation wine with dregs; Longan liquor karusen and lactic fermentation wine with dregs wine with dregs are distilled into the former wine of longan, blend into the longan liquor of different class through ageing.
