Yunnan arabica coffee bean preparation technology

Abstract

The invention discloses a Yunnan arabica coffee bean preparation technology. The Yunnan arabica coffee bean preparation technology includes: subjecting fresh coffee cherries to mechanical peeling within 12 hours after picking so as to separate coffee beans from peels thoroughly, subjecting the coffee beans to fermentation at normal temperature for 12 hours, adding 1.5 times of clean water to soak the coffee bean flesh for 12 hours, performing floatation and classification prior to airing surface moisture on the moist coffee beans with hulls, and transferring the coffee beans to a clean and peculiar-smell-free airing shelf for sun drying till 10-12.5% of water content is left; hulling by a huller, filtering imperfect coffee beans, removing small coffee beans with pore diameter smaller than 6 millimeters by a vibration classification screen, and removing all defective coffee beans in different colors by manual picking-up to obtain primary coffee beans; lightly baking the primary coffee beans for 8-12 minutes by controlling the out-of-pot temperature of the coffee beans to range from 190 DEG C to 195 DEG C and the chromaticity of the coffee beans to range from 95 degrees to 130 degrees so as to obtain target objects. The Yunnan arabica coffee bean preparation technology has the advantages that simple technology and low cost are achieved, excellent savory and mellow degree and acidity degree of Yunnan coffee beans are highlighted on the premise that quality of the Yunnan coffee beans is guaranteed, and parameters and indexes in the primary Yunnan coffee bean processing process are provided.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation process of Yunnan arabica coffee beans. Background technique [0002] Coffee arabica is suitable for growing in mountainous areas with an altitude of 800-1800 meters. If the altitude is too high, the taste will be sour, and if the altitude is too low, the taste will be bitter. Most arabica coffees are planted in hot and dry valleys at an altitude of about 1100 meters, so they have a moderate sour taste and a rich and mellow aroma. Many areas in Yunnan have a unique environment suitable for the growth of arabica coffee, and the quality of the arabica coffee produced is excellent. The planting areas are mainly distributed in Lincang, Baoshan, Simao, Xishuangbanna, Dehong and other prefectures. The average temperature in the coffee-growing areas of Yunnan is 17-22°C, the highest is 40.4°C, and there is basically no frost all year round. The arabi...

Problems solved by technology

Due to the unique natural environment such as low latitude, high altitude, large temperature difference between day and night, and brick red soil, the coffee beans of small grains in Yunnan have the characteristics of thick but not bitter, fragrant but not strong, and slightly fruity sour. The current coffee bean processing methods cannot fully Highlight the excellent aroma and acidity of Yunnan arabica coffee beans
