FIELD: food industry.
SUBSTANCE: group of invention relates to coffee industry and particularly to application of a stabilised enzyme compositions in production of coffee products. The dry stabilised enzyme composition contains a hydrolase enzyme and an efficient quantity of coffee material promoting stabilisation in a quantity approximately 1 - 25% of the enzyme and approximately 75 - 99% of the coffee material. The method for production of a soluble coffee extract involves roasted solid coffee substances treatment to produce a coffee suspension containing solid coffee substances, the coffee suspension treatment with an effective quantity of the enzyme in the form of the stabilised enzyme composition at the temperature and during the time sufficient for hydrolysis of the solid coffee substances to produce a soluble coffee extract material, the soluble coffee extract material treatment to produce a soluble coffee extract. The semi-continuous or continuous method of the soluble coffee extract production envisages treatment of finely ground solid coffee substances with an effective quantity of the enzyme in the form of the stabilised enzyme composition for hydrolysis of the solid coffee substances to produce a soluble coffee extract material containing a soluble coffee extract, the soluble coffee extract material circulation through a separator device with a semi-permeable membrane for continuous retentate and permeate generation. The permeate contains a soluble coffee extract and is continuously collected in the reactor while the retentate is at least partially recirculated into the vessel.
EFFECT: group of inventions enables production of a stabilised enzyme composition that retains enzyme stability and activity during storage without usage of stabilisers and/or incorrect application during usage of solely the coffee materials.
