Abstract

The present invention discloses a preparation method of rhodomyrtus tomentosa fruit concentrated juice. The rhodomyrtus tomentosa fruit concentrated juice is prepared by the following raw materials in parts by weight. The rhodomyrtus tomentosa fruits are beat into slurry, the slurry is subjected to a color protection, and the color protected slurry is enzyme deactivated to obtain an enzyme deactivated slurry; the enzyme deactivated slurry is filtered and squeezed to obtain fruit juice, and amylopectin is added to obtain a fruit juice suspension; a microfiltration membrane is used to conduct a micro-filtering and clarifying of the fruit juice suspension, carried fruit juice is obtained, an ultrafiltration membrane is used to conduct an ultra-filtering and concentrating, an ultrafiltration membrane trapped liquid and an ultrafiltration membrane permeated liquid are obtained, a vacuum evaporation device is utilized to concentrate the ultrafiltration membrane permeated liquid to be 35-45 degree Bx, a vacuum concentrated juice is obtained, the vacuum concentrated juice and the ultrafiltration membrane trapped liquid are mixed, the mixture is sterilized, and the sterilized mixture is filled to obtain the finished products. The amylopectin is added as an adsorbent before the membrane filtration, which is good in the adsorbability of impurities and can targetedly remove non-nutrient substances. The microfiltration membrane can trap the starch and the adsorbed impurities, so that the nutrient flavor substances can be retained.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing concentrated twist fruit juice. Background technique [0002] Twisted fruit is also called myrtle, and there are the following aliases Hypericum, Shanrenzi, Shanshen, Duolian, Dou Rengan, Duo milk, Shan Duo milk, Su Yuanzi, pomegranate seed, white mill, Gang Ren, water knife Lian, Wudu, Danglizi, Duo Moo Zai and so on. Myrtle is the fruit of the Myrtle plant Myrtle, also known as Myrtle, Zhazi, Shanzhu, Zhongni. Myrtle fruit is a wild fruit produced in the subtropical zone. It is born in hills, wilderness and roadsides. It can also be artificially planted in large areas. It is a wild plant resource with extensive development and utilization value. . According to the "Dictionary of Chinese Medicine", myrtle fruit is famous for nourishing blood, nourishing beauty, and improving eyesight. It can be used to treat various anemia, physical weakness, nocturnal em...
