The invention discloses a technology for preparing a
hippophae rhamnoides
fruit juice beverage by quick-freezing separation and superhigh pressure sterilization. The technology comprises the steps ofquickly freezing
hippophae rhamnoides twigs and fruits, taking the fruits, performing
mashing, performing
colloid milling, performing homogenizing, performing enzymolysis, performing sheet frame filtering, performing vacuum material preparation, performing canning, and performing superhigh pressure sterilization, wherein normal-temperature water is used as a medium, and sterilization is performedat the sterilization pressure being not less than 500Mpa for at least 15 minutes. The technology has the following advantages that the degree of perfection of the
hippophae rhamnoides fruits is guaranteed, the destroying of the
hippophae rhamnoides fruits in the process for separating twigs from fruits is reduced, and the raw materials are fresh, nutritive and safe; and a biological
enzyme methodis adopted for wall breaking
on cells, which is favorable for
dissolution of effective components of
multiplex vitamins, fat,
organic acid, flavone, and the like. A superhigh pressure normal temperature sterilizing technology is adopted, so that destroying of high temperature to
heat sensitive nutrient components is avoided, and sterilization effects of products are guaranteed; and besides, few cells which are not broken, in the
fruit juice, are further broken, so that the raw materials are uniform in components, the
nutrient is easy to absorb, and the products are full in mouth feel and fineand smooth.
