SEA-BUCKTHORN CONCENTRATE PRODUCTION METHOD Russian patent published in 2012 - IPC A23L2/00 

FIELD: food industry.

SUBSTANCE: invention relates to berry concentrates production. Characteristically the method for sea-buckthorn concentrate production is as follows: one crushes sea-buckthorns to produce mash, maintains the mash during 10-15 minutes at a temperature of 40-45°C, one proceeds with introducing into it a mixture of enzymic preparations i.e. Fructozym colour and Laminex BG at a ratio of the mash to the enzymes mixture equal to 100 g - 0.025 g. Then one performs (while continuously stirring) hydrolysis during 1-2 hours at a temperature of 40-45°C, heating of the mixture up to a temperature of 80-85°C, maintenance during 1-2 minutes, cooling to a temperature of 30-40°C. Then one proceeds with separation into the liquid fraction (with dry substances content equal to 10-11%) and the solid residue by way of pressing; then the liquid fraction is concentrated under vacuum at a temperature of 50-70°C. The ratio of enzymic preparations in the mixture is equal to 1:1; dry substances content in the concentrate is equal to 45-50%. Before concentration one may mix the liquid fraction with sugar at a ratio of 1:1; after addition of sugar the dry substances content in the concentrate is equal to 70-72%.

EFFECT: method ensures juice yield increase by 18-20%, additionally - increase of yield of biologically active berry components: organic acids - 1,25 times, vitamin C - 1,2 times and sugars - 1,4 times.
