Technology for preparing hippophae rhamnoides fruit juice beverage by quick-freezing separation and superhigh pressure sterilization

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of food production, in particular to a preparation process of seabuckthorn juice drink. Background technique [0002] Seabuckthorn (scientific name: Hippophae rhamnoides Linn.), also known as vinegar willow and blackthorn, is a plant of the genus Hippophae in the family Echinaceae. It is distributed in North China, Northwest, Southwest and other places, and is drought-resistant and wind-sand resistant. The content of vitamin C in the fruit of seabuckthorn is high, and it is called "the king of vitamin C". Seabuckthorn is an important biological resource integrating ecological, economic and health functions. Seabuckthorn juice is rich in various vitamins and organic acids, including 6 kinds of soluble vitamins, 22 kinds of fatty acids, 42 kinds of lipids, and 33 kinds of flavonoids and phenols. function, lowering blood pressure, lowering cholesterol and triglycerides, promoting blood circulation and dispell...

Problems solved by technology

Due to the long storage time of raw materials, the active ingredients of this kind of products are degraded and browned, and the high sterilization temperature destroys the nutrients and aromatic substances such as vitamins and carotene in seabuckthorn juice, resulting in low nutritional value of the products. Monotonous flavor
