Embodiment 1

[0017] Embodiment 1: a kind of preparation method of concentrated seabuckthorn clear juice, comprises the following steps:

[0018] A preparation method of concentrated seabuckthorn clear juice, comprising the following steps:

[0019] Put the branches and fruits of seabuckthorn in a cold storage at -35°C for 8.5 hours, then use a fruit-threshing and sorting machine to remove and sort them to obtain seabuckthorn fruits. After washing with water at 20°C, the seabuckthorn fruits are sprayed with pure water , use a crusher to crush seabuckthorn fruit, add seabuckthorn fruit quality 0.8‰ cellulase for enzymolysis for 40min, use a belt press to squeeze, separate the pomace, and obtain seabuckthorn raw juice, according to the mass ratio of 1:1 to Add pure water at 25°C to rehydrate the pomace for 20 minutes, squeeze the rehydrated pomace again, and obtain the original seabuckthorn juice again;

[0020] Heat the raw seabuckthorn juice to 70°C for pasteurization, then cool it down to...

Embodiment 2

[0022] Embodiment 2: a kind of preparation method of concentrated seabuckthorn clear juice, comprises the following steps:

[0023] Put the branches and fruits of seabuckthorn in a cold storage at -40°C for 9 hours, then use a fruit-threshing and sorting machine to remove the fruits and sort them to obtain seabuckthorn fruits. After washing the seabuckthorn fruits with water at 22°C, spray them with pure water. Use a crusher to crush the seabuckthorn fruit, add cellulase with a quality of 2‰ of the seabuckthorn fruit to carry out enzymatic hydrolysis for 45 minutes, use a belt press to squeeze, separate the pomace, and obtain the original fruit juice of seabuckthorn. Add pure water at 28°C to the pomace for rehydration for 25 minutes, and squeeze the rehydrated pomace again to obtain the original seabuckthorn juice;

[0024] Heat the raw seabuckthorn juice to 75°C for pasteurization, then cool it down to 45°C and add pectinase and protease with a quality of 2‰ of the raw seabu...

Embodiment 3

[0026] Embodiment 3: a kind of preparation method of concentrated seabuckthorn clear juice, comprises the following steps:

[0027] Put the branches and fruits of seabuckthorn in a cold storage at -40°C for 10.5 hours, then use a fruit-threshing and sorting machine to remove and sort them to obtain seabuckthorn fruits. After washing with water at 25°C, the seabuckthorn fruits are sprayed with pure water , using a crusher to crush the seabuckthorn fruit, and adding cellulase with a quality of 4‰ of the seabuckthorn fruit to carry out enzymatic hydrolysis for 50 minutes, using a belt press to squeeze, separate the pomace, and obtain the original fruit juice of seabuckthorn, in a mass ratio of 1:1, Add pure water at 30°C to the pomace to rehydrate for 30 minutes, and squeeze the rehydrated pomace again to obtain the original seabuckthorn juice;

[0028] Heat the raw seabuckthorn juice to 85°C for pasteurization, then cool it down to 50°C and add pectinase and protease with a qual...

Abstract

The invention discloses a concentrated sea-buckthorn clear juice and a preparation method thereof. The preparation method comprises the following steps: (1) washing, crushing, enzymatically hydrolyzing and squeezing sea-buckthorn fruits orderly, separating out fruit residue to obtain a raw sea-buckthorn juice, and rehydrating the fruit residue and squeezing again to obtain the raw sea-buckthorn juice; (2) pasteurizing the sea-buckthorn juice, adding an enzymic preparation for further enzymatic hydrolysis, and separating out the extracted sea-buckthorn fruit oil to obtain the sea-buckthorn juice; (3) orderly performing ultrafiltration, decoloration, reverse osmosis membrane concentration and concentration by use of a quadruple effect vacuum evaporator on the sea-buckthorn juice, thereby obtaining the concentrated sea-buckthorn clear juice. According to the preparation method of the concentrated sea-buckthorn clear juice, twice enzymatic hydrolysis, twice squeezing and twice concentration are adopted in the process of preparing the concentrated sea-buckthorn clear juice, and therefore, the fruit juice extraction rate is increased and nutritional ingredients in the fruit juice are not damaged and lost; meanwhile, the preparation method is energy-saving, low in consumption and low in production cost; the prepared sea-buckthorn clear juice has relatively high sugar degree, acidity, color value and light transmittance, and is stable in quality and easy to store.

Description

technical field [0001] The invention relates to the technical field of seabuckthorn clear juice, in particular to a concentrated seabuckthorn clear juice and a preparation method thereof. Background technique [0002] Seabuckthorn is a natural berry plant, its fruit contains a variety of nutrients, known as "the third-generation fruit", "the king of vitamins" and "the most promising raw material for new health products in the 21st century". Seabuckthorn fruit contains more than 190 kinds of biologically active ingredients. It is a rare miraculous plant that integrates protein, unsaturated fatty acids, vitamins, and flavonoids (VP). It is called "vitamin treasure house". Its Vc content is 3-6 times that of the so-called "Vc" king kiwi fruit, its bioflavonoid content is higher than that of ginkgo biloba, and its β-carotene and VE content are higher than other fruits. Seabuckthorn and its deep-processed products have the functions of nourishing the stomach and strengthening th...
