Abstract

The invention discloses a method for producing a fortified fruit wine by using a pulsed electric field assisted supercritical CO2 fluid. The method is implemented through juicing litchi, longans and pineapples and the like with low sugar content, carrying out full-juice fermentation, when the fermented alcohol content reaches 6% (V / V), stopping fermenting, treating the obtained object by using a pulsed electric field, carrying out supercritical CO2 fluid extraction, then quickly reducing the pressure to 4-6 MPa, raising the temperature to 50-60 DEG C, separating the extracted substance, cooling to 5-8 DEG C, and carrying out constant-temperature airtight preservation; vacuumizing residual raffinate after extraction so as to obtain a concentrated liquid; and finally, adding abstract into the concentrated liquid, and carrying out ultrafiltration, so that the fortified fruit wine is obtained. The fortified fruit wine brewed according to the invention is full-bodied in fruit flavor, rich in ester substances, fresh and smooth in taste, and low in fusel oil content, therefore, the wine does not go to the head after being drunk more. The method is suitable for brewing a fortified fruit wine by using fruits with low sugar content, simple in process and low in cost.

Description

technical field [0001] The invention relates to a processing method of fruit wine, in particular to a pulse electric field assisted supercritical CO 2 The invention discloses a method for fluid production of enhanced fruit wine, which belongs to the technical field of fruit wine production. Background technique [0002] Guangdong area is rich in fruits such as lychee, longan and pineapple. Except some fruits are used as fresh fruits, fermenting fruit wine to brew fruit wine is an emerging processing direction in recent years. [0003] Compared with wine-making grapes, fruits such as lychee, longan, and pineapple have low sugar content. If no exogenous sugar is added during the fermentation process, generally only 8-10.5% (V / V) alcohol can be reached after complete fermentation There is a gap between the alcohol content of 12-14% (V / V) of fruit wine, so general fruit wine companies use artificial sugar sources to increase the alcohol content of fermentation.
