Beverage by juicing of grapefruit after freezing and preparation method thereof

Abstract

The invention relates to a beverage by juicing of grapefruit after freezing and a preparation method thereof. The preparation method comprises the following steps of 1, selecting grapefruits without diseases or pests and pest biting, cleaning, putting into a refrigerator, freezing for 24 to 48h at the temperature of -20 to -25 DEG C, fetching out, standing for 6 to 8h at normal temperature, thawing, and juicing for further use; 2, selecting lily bulb, semen nelumbinis, tremella fuciformis and red date without diseases or pests and pest biting, cleaning, putting into a container, adding a proper amount of water, decocting for 2 to 3h, extinguishing fire, cooling, filtering when the temperature is reduced to normal temperature, removing residues, and obtaining liquid for further use; 3, adding the juice in step 1 into the liquid in step 2, uniformly stirring, standing for 8h, filtering by a 200-mesh filter cloth, bottling, sterilizing at the temperature of 90 DEG C, and capping, so as to obtain a finished product.

Description

technical field [0001] The invention relates to a beverage prepared by squeezing pomelo after freezing and a production method thereof, belonging to the field of food processing. Background technique [0002] At present, the fruit drinks sold in the market are made of freshly squeezed juice or freshly squeezed juice after boiling. Without freezing treatment, the sugar in the fruit is not sufficiently extracted, and the enzyme bacteria contained in the fruit cannot be destroyed. Thorough killing will affect the shelf life of the fruit juice. Therefore, it is an important topic for scientific and technological personnel to study fruit drinks that can fully extract the sugar content contained in the fruit and have a longer shelf life. Contents of the invention [0003] The purpose of the present invention is to provide a kind of beverage which is not only rich in nutrition but also unique in flavor and has a long shelf life prepared by squeezing pomelo after freezing.

Problems solved by technology

[0002] At present, the fruit drinks sold in the market are made of freshly squeezed juice or freshly squeezed juice by boiling. Without freezing treatment, the sugar in the fruit is not sufficiently extracted, and the enzyme bacteria contained in the fruit cannot be digested. Thorough killing will affect the shelf life of fruit juice. Therefore, research on fruit drinks that can fully extract the sugar contained in fruits and have a longer shelf life is an important topic for scientific and technological personnel.
