Processing method of concentrated hippophae rhamnoides fruit clear juice

Abstract

The invention provides a processing method of concentrated hippophae rhamnoides fruit clear juice, relates to the processing technologies of hippophae rhamnoides fruit juice, and solves the technicalproblem that the nutrient components in hippophae rhamnoides fruits can be destroyed in the preparation process of hippophae rhamnoides fruit clear juice. The method includes the following steps: step1, quickly freezing hippophae rhamnoides branch fruits; step 2, separating and screening hippophae rhamnoides pure fruits with good quality; step 3, cleaning and thawing the hippophae rhamnoides purefruits, and performing beating and juicing to obtain juice A and seed skin residues; step 4, performing coarse filtration on the juice A, performing heating, and performing refining and separation toobtain a material A; step 5, continuing heating the material A, and performing separation to obtain fruit oil, pulp and juice B; step 6, performing enzymolysis on the juice B, and performing separation and filtration to obtain a filtrate A with a color value (T440) not less than 60% and the light transmittance (T625) not less than 85%; and step 7, performing evaporation and concentration on the filtrate A at a low temperature to a sugar content of 65-70BIX to obtain the concentrated hippophae rhamnoides fruit clear juice. The method is scientific and reasonable in process and convenient to operate, and ensures that the nutrient components and active substances of the hippophae rhamnoides fruits are not destroyed to maximum extent.

Description

Technical field [0001] The invention relates to a sea-buckthorn juice processing technology, in particular to a processing method of concentrated sea-buckthorn clear juice, which is used to obtain sea-buckthorn juice while retaining nutrients in the sea-buckthorn to the maximum. Background technique [0002] Sea buckthorn (Latin scientific name: Hippophae rhamnoides Linn.), is a deciduous shrub of the Elaeagnus family and the genus Hippophae. Its characteristics are drought-tolerant, cold-tolerant, barren-tolerant and wind-sand-resistant. It is widely used in water and soil conservation. [0003] Northwest China is arid and rainless, and the land is barren. In most areas, it is difficult for trees to survive or grow into small old trees, and it is very difficult for vegetation to recover. Seabuckthorn has the characteristics of cold tolerance, drought tolerance, and barren tolerance, so it is planted in large quantities in northwestern my country for soil and water conservation, w...

Problems solved by technology

[0006] At present, the production process of seabuckthorn juice generally includes juicing, high-temperature sterilization, filling and other processes, but the loss of VC, the main nutrient in seabuckthorn, is very serious at high temperature, and in the processing of juice, thermal processing seriously damages the juice. Nutrition and mouthfeel, in order to solve the above-mentioned technical problems, the present invention provides a kind of processing method of concentrated seabuckthorn clear juice
