Abstract

The invention relates to fruit wine, particularly discloses raspberry fruit wine and a method for preparing the same, and belongs to the technical field of fruit wine. The raspberry fruit wine is mainly prepared from, by weight, 100-150 parts of raspberry freeze-dried powder, 30 parts of white granulated sugar, 5-6 parts of food stabilizers and 3-4 parts of capsanthin. A process for preparing the raspberry freeze-dried powder includes thoroughly cleaning raspberries and then drying the raspberries by means of freezing under certain freeze drying conditions; smashing the raspberries after the raspberries are dried by means of freezing and sieving the raspberries by the aid of 40-mesh sieves. The certain freeze drying conditions include that the pressures of drying chambers are 100-110 Pa, the temperatures of heating plates are 42.5-45 DEG C, and the cooling rates are 0.3 DEG C / min. The raspberry fruit wine and the method have the advantages that the raspberries are dried by means of freezing at first and then are fermented to make wine, accordingly, the raspberry fruit wine prepared by the aid of the method has strong aroma of the raspberries and sweet and mellow taste, is fresh, pleasant and pure and is fruit wine with excellent quality, and aftertaste of the raspberry fruit wine is durable and can be enhanced with age.

Description

technical field [0001] The invention relates to the technical field of fruit wine, in particular to raspberry fruit wine and a preparation method thereof. Background technique [0002] Raspberry is a perennial deciduous shrub-type fruit tree of the Rosaceae Rubus genus, also known as tray, Rubus, etc., and Chinese herbal medicine calls it raspberry. Raspberry has the advantages of good ecological benefits, strong resistance to diseases and insect pests, high investment returns, simple management techniques, and long industrial extension chains. At the same time, because of its special nutritional and health functions, it is widely recognized by consumers from all over the world, and is known as "golden fruit" in the international market. [0003] Raspberries are rich in 21 kinds of amino acids and multivitamins necessary for the human body, among which eight kinds of amino acids cannot be synthesized by the human body but play an important role in human metabolism. Raspber...
