Abstract

The invention relates to cold-soluble freeze-dried coffee and a preparation method thereof, and belongs to the technical field of food processing. The cold-soluble freeze-dried coffee is prepared from, by weight, 42-50% of Colombia coffee, 5-8% of Khatisk coffee, 10-20% of Blue Mountain coffee, 12-20% of Mocha coffee, 8-15% of Java coffee and 5-12% of Ethiopian coffee. The preparation method of the cold-soluble freeze-dried coffee sequentially includes the operation steps of baking, grinding, extraction, centrifugation, evaporation and freeze drying. According to the cold-soluble freeze-driedcoffee and the preparation method thereof, by adopting a freeze-drying technology, the cold-soluble freeze-dried coffee is prepared, aromatic substances with high heat sensitivity in coffee beans arereserved, the cold-soluble freeze-dried coffee is rich in fragrance and pure and mild in taste, and the solubility in drinking water at 0 DEG C, 25 DEG C and 80 DEG C is 100%, so that brewing withouthot water or boiled water is convenient.

Description

technical field [0001] The invention relates to a cold-melt freeze-dried coffee and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] With the continuous improvement of people's living standards and the continuous acceleration of the pace of life, the fast-moving consumer beverage market has developed rapidly. Since the birth of instant coffee in 1938, restoring the flavor and taste of roasted and ground coffee has always been the direction of continuous efforts of instant coffee producers. And gradually developed three generations of instant coffee products: "spray-dried coffee", "condensed flavored coffee" and "freeze-dried coffee". Among them, the freeze-dried coffee produced by vacuum freeze-drying technology is the instant coffee with the best quality, flavor and taste in the world at present. The damage of coffee quality has kept the flavor and mouthfeel of roasted and ground coffee intact, and the quality...
