Abstract

The invention discloses a preparation method of a red grape juice powder dry extract. The preparation method comprises the following steps: selecting raw materials; cleaning; heating; extracting juice; removing jam: adding fruit juice enzyme to grape juice extracted from the last step, and removing jam by virtue of a centrifuge at 3600L / h; after separating the jam, carrying out enzyme deactivation on the grape juice by virtue of a plate heat exchanger or a tubular disinfector at 85 DEG C for 15s; after carrying out the enzyme deactivation, immediately cooling to be less than 45 DEG C; after processing complex enzyme, filtering by virtue of a diatomite filter, wherein the addition is 0.5-1% of the volume of the fruit juice; concentrating in a vacuum environment by virtue of a falling-film or forced circulating low-temperature vacuum concentrating device; cooling the concentrated grape juice to minus 2 DEG C by virtue of a cooler, standing in a tank for a night until a considerable number of tartar deposits are separated on the bottom layer, filtering supernatant, filling filtrate in a stainless steel tank, and refrigerating the filtrate for the second time and the third time at minus 5- minus 7 DEG C so as to remove tartar; decompressing and concentrating the concentrated juice regulated by the last step, and spray-drying so as to obtain the dry extract.

Description

technical field [0001] The invention relates to the field of medicine extraction, in particular to a dry extract of red grape juice powder and a preparation method thereof.
