Abstract

The invention discloses a preparing method of a freshly-squeezed pyrus ussuriensis carbonate beverage. The method includes the following steps of selecting pyrus ussuriensis fruits with the measured hardness of 2.5-3.2 kg/cm<2>, conducting cleaning and direct squeezing on the whole fruits without removing peel or kernels, putting 0.2-0.5% of ascorbic acid into juice to be evenly stirred, removinglarge granules in the juice, mixing and filling the pyrus ussuriensis juice which is prepared by evenly mixing, by weight, 70-86 parts of juice, 1-5 parts of sodium fluoride, 1-5 parts of citric acid,1-5 parts of xylitol and 1-5 parts of sodium bicarbonate, clearing the juice to remove impurities of the juice, conducting high-pressure carbon dioxide sterilizing, adding 50-100 parts of a saturatedcarbon dioxide water solution, and conducting packaging and mouth sealing. The method has the advantages that labor is saved, nutrients are rich, the nutrients are not greatly different from those infresh fruits, and the flavor and taste are better.
