Abstract

In the production process of frozen pear and frozen pear juice, pear is processed through washing, disinfection and freezing to produce frozen pear and the frozen pear is stored in refrigerator. The inferior frozen pear is produced into frozen pear juice through defreezing, wind drying, crushing deseeding, squeezing and bottling. The frozen pear product contains no chemical matter and has good taste and rich nutrients and the frozen pear juice may be produced in low cost and the year round.

Description

The technology that pears and frozen pear juice are frozen in processing

The present invention relates to the technology that a kind of fruit stores deep processing, the technology of pears and frozen pear juice is frozen in specifically a kind of processing.

At present, the storage of fruit can only be fresh-keeping storage, can not carry out stored frozen, and the fruit of stored frozen thaws, and edible peculiar smell just to occur be not the taste of fruit in the back.Fresh-keeping storage is just put into special cellar for storing things to the fruit that will store up, and the temperature in the control cellar for storing things, humidity prolong the edible phase thereby reach fresh-keeping purpose in certain scope.Its weak point of this kind storage method is the longest the depositing at the end of spring and the beginning of summer of fruit of plucking autumn, if the condition of storage is improper perishable; The long-time storage causes the fruit nutrition composition to descend the not good phenomenon of mouthfeel during food.Be with a kind of fruit ussurian pear of abounding with for the northern area of China west of Liaoning one especially, fresh-keeping storage has more certain difficulty, uses best storage method and also can only deposit early spring, has more out of the question eaten this kind pears during the broiling summer.

The purpose of this invention is to provide one and the processing technology of freezing pears and frozen pear juice, make people during the broiling summer or other season edible to taste brighter freeze pears and frozen pear juice.

Realize that the concrete scheme that the technology of pears and frozen pear juice is frozen in purpose processing of the present invention is: will purchase the ussurian pear graduation that comes and clean decontamination, send into freezer after disinfecting and freeze the corresponding time of system, the pears packing warehouse-in stored frozen with certain grade that makes is for sale freezing; In freezer, take out and be transported to the pond that thaws and thaw that to handle the back air-dry for freezing the inferior pears that make, go then handle, fragmentation, dilution branch leave away seed, squeeze the juice, juice bottling warehouse-in is for sale.

The technology that pears and frozen pear juice are frozen in the present invention's processing is to adopt freezing method to store to freeze pears and its off standard is processed into frozen pear juice.Because store after the method can make the pears snap frozen, easy control of temperature in the storage gets final product without antistaling agent, anticorrisive agent, the putrefactive phenomenon of pears takes place when avoiding storing, and can reach long term storage and never degenerate, and keeps its nutrition, and mouthfeel is good when edible.Particularly suck during the broiling summer after thawing to freeze the pears taste better.

Make further instruction below in conjunction with the technology that specific embodiment freezes pears and frozen pear juice to the present invention's processing.

Ussurian pear that can stored frozen is ripe late than other fruit of the north, and this fruit is the bluish yellow look when ripe, and well-done is golden yellow, is the grey black look after freezing, be with in the fruity acid sweet, the juice content height, mouthfeel is good, has very high edibility.Not enough is that this really is difficult for storing, and storage is no more than two months and will rots under the natural conditions, loses due value.Gu this utilizes its characteristic research to go out the production technology that pears and frozen pear juice are frozen in a cover processing.The concrete steps and the implementation method of this technology are: in the ussurian pear mature period, pears are big by it, little and quality quality are told different grade purchases and are come the back to send into respectively by grade to carry out decontamination in the automation cleaning machine and clean, fruit after cleaning up is transported to and carries out the sterilization processing in the disinfecting and sterilizing machine, make it to reach corresponding food hygienic standard, be conveyed into then and freeze system in the freezer, the output freezer is packed processing after freezing the corresponding time of system, packing can divide a kilogram weight one parcel, send into finished product freezer stored frozen behind the big bag with integrated 20 kilogram weights of parcel again, refrigeration is sold in consumer's hand edible according to user's needs.This eating method that freezes pears be with this freeze pears put into cold water thaw form one deck thin ice to the crust of pears after the deicing layer go the pears skin edible.This kind freezes pears need not any antistaling agent, without putrefaction during the anticorrisive agent storage, and the storage time is normal, equal edible throughout the year, and mouthfeel is good when edible, and nutritive value is abundant, is pure pollution-free food.

For the pears that freeze of freezing back off standard, can't direct marketing, only being processed into pear juice could be eaten by the consumer.Its processing step of producing frozen pear juice is: off standard is frozen put into the pond that the thaws processing of thawing after pears take out in freezer, thaw it to be pulled out after dissolving to ice and drench the globule of sending into after anhydrating in the apparatus for drying the pears surface and remove, it is broken manually to go handle to send in the disintegrating machine then again, dilute separation after being crushed to a certain degree, send into the frozen pear juice of squeezing out in the squeezer after thoroughly separating the pears seed totally, preserve juice bottling back low temperature for sale.Its pears slag is given feed-processing plant as the feed addictive direct marketing.Use this explained hereafter frozen pear juice and be not subject to seasonal restrictions, thereby reduce cost, and the pear juice nutrition of producing is many, be with sweet mouthfeel good in the drinking acid, thereby enlarge sales volume, increase economic efficiency.

The present invention except that the production and processing technology of freezing and frozen pear juice of protection ussurian pear, but also be the scope that invention keeps for freezing this technology of processing storage application of other frozen fruits.

Claims

1, the technology of pears and frozen pear juice is frozen in a kind of processing, it is characterized in that: the operation of this technology is to clean decontamination after pears are graded, send into freezer after disinfecting and freeze the corresponding time of system, takes out the freezer of packing into after the packing again and stores for sale; Freeze the inferior pears that make and in freezer, take out and put into the pond that thaws and thaw that to handle the back air-dry, go then handle, fragmentation, dilution branch leave away seed, squeeze the juice, juice bottling warehouse-in is for sale.
