The above-mentioned sea buckthorn juice concentration technology that the present invention provides have employed the concentration of juices equipment of present invention design, can will concentrate pressure
Controlling in the range of technological requirement with thickening temperature, arranging concentration pressure is 1000Pa-2000Pa, and thickening temperature is 15 DEG C-30 DEG C
Time, the color approximation primary colors of the Fructus Hippophae concentrated fruit juice being concentrated to give under above-mentioned pressure and temperature environment, colour-darkening does not occurs
Situation；The present invention finds Fructus Hippophae Fresh Juice to be 1000Pa-2000Pa at pressure by great many of experiments, and thickening temperature is
15 DEG C-30 DEG C prepare under environment, Fructus Hippophae concentrated fruit juice colour-darkening after water dilutes can be avoided in non-additive situation
Phenomenon, special fruit this for Fructus Hippophae, wherein contain relatively polyphenols, prior art is kept away usually through adding antioxidant
Exempt from sea buckthorn juice oxidized and metachromatism occurs, but for sea buckthorn juice, the composition phenol special due to it is more, even if adding
Antioxidant is to prevent sea buckthorn juice variable color, and its effect is not got better, because the aldehydes matter in sea buckthorn juice is than conventional antioxygen
Agent is easier to oxidation, and therefore prior art is want to avoid metachromatism completely by the means adding antioxidant, and its effect is poor,
Therefore, the present inventor discharges the thinking of chemical reaction and considers from physical means, is put into by sea buckthorn juice under specified pressure temperature environment,
Especially the moisture in sea buckthorn juice can be steamed under condition of ultralow temperature, make use of the principle of boiling point substance step-down under high pressure, design
The process conditions of the present invention, the most specifically operate pressure and temperature, avoid the original one-tenth in sea buckthorn juice under this ultra low temperature
Divide destroyed, moisture in sea buckthorn juice also can be made to be evaporated, finally give satisfactory Fructus Hippophae concentrated fruit juice.
In the preparation method of the Fructus Hippophae concentrated fruit juice of the present invention, different from sterilizing after traditional first concentration, it is the most right to present invention employs
Fresh Juice carries out the technology that sterilizing carries out concentrating again, can reach that fruit juice sterilizing is uniform, effect preferable, easily operation and cost-effective.
The above-mentioned concentration of juices equipment using present invention design is the most simple to operate, and simple in construction, cost is less, can give birth in high volume
Producing concentrated fruit juice, improve yield, reduce energy consumption, the Fructus Hippophae concentrated fruit juice quality of colour prepared is preferable, production cost
Relatively low, it is often more important that to reach concentration of juices and invariant color by physical technique, fruit juice does not adds various additive, such as breast
Agent, thickening agent, antioxidant etc., the Fructus Hippophae concentrated fruit juice green pure of preparation is natural, and additive-free and Color Quality is preferable,
Meet people's hobby and market demands, bigger economic benefit can be brought.
The detailed description of the invention being only the present invention disclosed above, but protection scope of the present invention is not limited thereto, any familiar
Those skilled in the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain at this
Within the protection domain of invention.Therefore, protection scope of the present invention should be as the criterion with above-mentioned scope of the claims.
