Abstract

Melon and fruit juice is first produced with melon and fruitand through cleaning, peeling, pitting, crushing and eliminating dregs, and then spray or freeze dried and condensed at low pressure and low temperature to produce active melon and fruit water. The active melon and fruit water produced by the present invention has the biological activity and nutritive value of melon and fruit maintained.

Description

Production process of active melon and fruit water

The present invention relates to a kind of production technology of active water, particularly a kind of production process of active melon and fruit water.

In recent years, because the develop rapidly of science and technology, the technical merit of plantation melon and fruit has also obtained significant progress, and the single rate of melon and fruit rises rapidly at present, and the quality of melon and fruit also is greatly improved, and unprecedented good harvest scene occurred.But bring melon and fruit to have a good harvest thus, pin is motionless on market, causes a large amount of overstocking and since fresh melon and fruit between the storage life still in growth, be the active plant fruit, the long term storage difficulty is bigger, rots easily.In order to address the above problem, people carry out deep processing to melon and fruit, generally be melon and fruit to be manufactured melon and fruit goods such as melon and fruit can, melon and fruit drink, most of composition is sugar part in the melon and fruit goods, in process, adopt thermophilic digestion, through the melon and fruit of processing, because the boiling of high temperature makes the death of active plant fruit, therefore nutritions a large amount of in the melon and fruit are lost.

The objective of the invention is to provide a kind of production process of active melon and fruit water that can keep the melon and fruit nourishing composition.

The object of the present invention is achieved like this: select the bright melon and fruit of no scar, selected melon and fruit is cleaned, remove the Pi Jihe of melon and fruit after the cleaning, the melon and fruit digested tankage that obtains is broken, remove the melon and fruit slag after the pulverizing, promptly obtain melon and fruit Normal juice after removing the melon and fruit slag, melon and fruit Normal juice has been carried out drying, condensation process, promptly obtained active water after drying, the condensation.

The dry processing adopted spray-drying, condensation method or freeze drying, condensation method.

Spray-drying, condensation method are to place spray-drying, condensing plant to carry out drying, condensation melon and fruit Normal juice, pressure in spray-drying, the condensing plant container is the 0.1-0.9 atmospheric pressure, heat drying under this atmospheric pressure, 10 ℃-90 ℃ of heating and temperature control, condensation temperature are controlled at subzero 5 ℃-30 ℃.

Freeze drying, condensation method be with melon and fruit Normal juice place carry out in the freezing equipment freezing, freezing temperature is subzero below 20 degrees centigrade, solid content after freezing is put into pressure vessel, pressure in the pressure vessel is the 0.1-0.9 atmospheric pressure, under this atmospheric pressure to the solid-state melon and fruit Normal juice heat treated after freezing, heating and temperature control is at 10 ℃-90 ℃, and condensation temperature is controlled at subzero 5 ℃-30 ℃.

Owing to adopted such scheme, melon and fruit cleaning, peeling and the back of examining, pulverize, remove slag are obtained melon and fruit Normal juice, melon and fruit Normal juice is carried out spray-drying, condensation or freeze drying, condensation, melon and fruit Normal juice all is in to be lower than under normal atmosphere (An) and the low temperature and carries out in drying, condensation process, dry at low temperatures, condensation makes the active water of making can keep the biologically active of melon and fruit, various nutritions in the active water are not destroyed, effectively keep whole nutritive values of melon and fruit, reached purpose of the present invention.The production technology of this active water is simple, and easy operating can be converted into the bioactive water long preservation with bright melon and fruit, has kept the full nutrition composition, has thoroughly solved fresh fruit and has sold the short contradiction of shelf life, and the added value of melon and fruit is increased greatly.

Be described further with embodiment below.

Embodiment 1: select fresh watermelon, selected watermelon is cleaned, put into the skin that skinning machine removes watermelon after the cleaning, the watermelon meat that obtains is put into crusher for crushing, putting into centrifuge after the pulverizing separates watermelon Normal juice with watermelon slag, melon seeds, after separating, centrifuge promptly obtained watermelon Normal juice, watermelon Normal juice is carried out spray-drying, condensation process, its solid content falls into the bottom of equipment after dry the processing, the heat steam that produces in dry run has promptly obtained the active water of melon and fruit Normal juice through after the condensation.

Dry, condensation process adopts spray-drying, condensation method, spray-drying, condensation method are to place spray-drying, condensing plant to carry out drying, condensation melon and fruit Normal juice, pressure in spray-drying, the condensing plant container is 0.5 atmospheric pressure, heat drying under this atmospheric pressure, heating-up temperature is the moisture content start vaporizer when 50 ℃ of left and right sides, the moisture content of evaporation enters condensing tube condensation, condensation temperature is at 0 ℃, the active water that condensation obtains has kept the biologically active of watermelon and the nutrition in the watermelon fully.

Embodiment 2: the dry processing adopted freeze-drying, freeze-drying be with pears Normal juice place carry out in the freezing equipment freezing, make after freezing solid content in the pears Normal juice and pears moisture from, freezing temperature is at subzero 50 ℃, solid-state pears Normal juice after freezing is put into pressure vessel, pressure in the pressure vessel is 0.3 atmospheric pressure, under this atmospheric pressure to the solid-state pears Normal juice heat treated after freezing, heating and temperature control is about 30 ℃.Solid-state pears Normal juice promptly becomes the active water of pears after the water evaporates condensation after heating is thawed, the remaining solid content that is melon and fruit Normal juice falls into device bottom, and other and embodiment 1 omit together.
