Coffee flakes and process

摘要

A thin, transparent coffee glass is disclosed which is prepared by forming a mixture containing above 4% to 12% water and about 88% to above 96% total coffee derived solids. These solids can further contain up to 20% hydrolyzed mannan and oligomers having a DP from 1 to 10 and up to 10% coffee cellulosic sugars. The coffee melt is characterized by having a glass transition temperature between 30 DEG C. to 80 DEG C. The coffee melt is heated to a temperature of 60 DEG C. to 130 DEG C. and extruded into a thin continuous film, stretched to further form a thin film which is rapidly cooled into a hard coffee glass which is shiny on both sides, dark in color and transparent. This transparent glass is then dried to a stable moisture content. The coffee glass provides a shiny appearance to any coffee product it is combined with an is an excellent means of entrapping and protecting coffee aromas. Furthermore, the coffee glass provides a means for shaping numerous new coffee products. The thin flakes of coffee glass disolve rapidly.
