Abstract

The present invention relates to a processing method of ginkgo nut. Said processing method includes the following steps: soaking, disinfecting, cleaning, draining, cutting one end of ginkgo nut to form an opening, packaging, evacuating and cold-storing.

Description

A kind of processing method of ginkgo nut

Technical field

The present invention relates to a kind of food-processing method, relate in particular to a kind of processing method of ginkgo nut.

Background technology

For a long time, ginkgo all eats as medicinal and herbal cuisine, and eating method generally is edible with eating the ginkgo boiling raw and simmering roasting back, also has ginkgo edible after with the microwave baking.

Contrast is found after deliberation, is with shell ginkgo ratio not with the raciness of shell ginkgo, easier preservation; Stove fire is simmered the ginkgo raciness of roasting ginkgo than boiling, and nutrition and flavor loss are little; Simmer roasting ginkgo raciness with the band shell ginkgo of the instantaneous baking of microwave than stove fire, have that mouthfeel perfume (or spice) is glutinous, the characteristics of implication of endless appeal.

But also there are some problems in general microwave baking ginkgo.In Semen Ginkgo inside a cavity is arranged, air is arranged in the chamber,, all can make the band shell or do not blow with the ginkgo of shell because the microwave baking makes the instantaneous intensification of air in the cavity produce high pressure.And a core bud is arranged in the ginkgo cavity, the taste of core bud is very bitter and little poison is arranged, and directly influences edible mouthfeel, so we think that the ginkgo bitter is not very good eating when eating ginkgo usually.So some ginkgo processing enterprises require to extract the core bud, the still manual core bud of extracing of its most frequently used processing method, efficient is very low.

For instant, adopt following two kinds of methods to shell usually: 1, manual shelling, its efficient is low, cost of labor is high; 2, mechanical broken shell, its efficient height, but kernel breakage rate height, loss are big.But no matter adopt which kind of method, all can't efficiently remove the film clothing and the inner bitter core bud of kernel that are close on the kernel.

Summary of the invention

The object of the invention provides a kind of processing method of ginkgo nut, and it is low that it has solved existing ginkgo processing method working (machining) efficiency, the technical problem that goods nutrition and flavor loss are big, the back of shelling is difficult for preservation.

Technical solution of the present invention is:

A kind of processing method of ginkgo nut, its special character are that it comprises following procedure of processing:

1] ginkgo location: the end that the band shell ginkgo that preliminary treatment is good has a core bud is used clamp up;

2] in the shell of Semen Ginkgo upper shed: use cutter in the shell of Semen Ginkgo upper end open, until core bud place;

3] post-process treatment: the ginkgo behind the opening is vacuumized sealing refrigeration.

Above-mentioned procedure of processing also comprises

Pre-treatment step before the ginkgo location: will be with the shell ginkgo to soak, sterilize, clean, drain stand-by.

Above-mentioned procedure of processing also comprises

Heating using microwave step after the processing: the ginkgo that will vacuumize sealing refrigeration is put into micro-wave oven, and low firepower is heated to well-done.

Above-mentioned step in the shell of Semen Ginkgo upper shed comprises:

Open round mouth with cutter on shell of Semen Ginkgo, until core bud place, described cutter is the round bur head.

Above-mentioned step in the shell of Semen Ginkgo upper shed comprises:

Open 1-shaped open with cutter on shell of Semen Ginkgo, until core bud place, described cutter is thin blade.

Above-mentioned step in the shell of Semen Ginkgo upper shed comprises:

Open the cross mouth with cutter on shell of Semen Ginkgo, until core bud place, described cutter is thin blade.

Above-mentioned step in the shell of Semen Ginkgo upper shed comprises:

Open V font mouth with cutter on shell of Semen Ginkgo, until core bud place, described cutter is thin blade.The above-mentioned degree of depth in the shell of Semen Ginkgo upper shed is 1～3mm.

The above-mentioned degree of depth in the shell of Semen Ginkgo upper shed is preferably 1～2mm.

The present invention has following advantage:

1, unique flavor.Except heating using microwave can keep the peculiar flavour that the ginkgo dry fruit had to greatest extent, the HTHP air that heating using microwave produced is when opening part excretes, core bud in the cavity the inside also just ejects under the extruding at high pressure draught simultaneously, can not influence the mouthfeel of ginkgo; Meanwhile kernel shrinks in pressure release moment again after the high pressure instantaneous expansion, makes it be close to that film clothing on the kernel is also whole thereupon to come off with kernel, and the eater can peel off it very easily.

2, being convenient to batch production produces in batches.Anchor clamps of the inventive method and cutter meet the batch production batch production requirement, as long as make special production line, manually continuously ginkgo are put into anchor clamps except using when ginkgo is located, and all the other processes are all finished automatically by production line.

3, convenient, fast.Most of step of the inventive method all adopts production line processing, has avoided the shortcoming that traditional diamond-making technique processing is loaded down with trivial details, process is restive.Owing to need not to remove shell, working (machining) efficiency improves greatly.

4, health.This method adopts production line processing, has avoided traditional diamond-making technique to use artificial antihygienic shortcoming of bringing; In addition, the present invention adopts the method for band shell cleaning and sterilizing, and the various harmful components that produce when cleaning and sterilizing do not reach the edible part of food substantially, and security and storage endurance that this has just improved food greatly meet the food hygiene processing request.

5, can use heating using microwave.The inventive method adopts unique processing mode, has avoided the air burst in the ginkgo cavity, so can use heating using microwave.

The explanation of accompanying drawing drawing

Fig. 1 is a ginkgo internal structure schematic diagram;

Fig. 2 is the structural representation behind the shell of Semen Ginkgo opening;

Wherein: 1-shell of Semen Ginkgo, 2-kernel, 3-cavity, 4-core bud, 5-opening.

The specific embodiment

The process of the inventive method comprises:

At first will be with the shell ginkgo to soak, sterilize, clean up; The ginkgo that to soak is pulled out and drains again, and an end that ginkgo nut is had the core bud is placed in the anchor clamps on the conveyer belt up as Fig. 1 then, successively by under the cutting tool, the disposable opening that is processed into of an end that makes it that core bud be arranged, the opening core bud place to the kernel is as Fig. 2; At last the gingko foodstuff that processes just can be packed vacuumize the warehouse-in stored refrigerated.People only need the cryopreserved ginkgo in processing back is put into micro-wave oven when edible, and firepower transfers to low-grade heating and gets final product for 20 seconds.Anchor clamps can adopt various forms, and with energy conveniently assemble and disassemble ginkgo, clamping is firm, does not damage ginkgo and is advisable.The circular drill bit that can adopt rotation at a high speed during opening and can move up and down is opened round mouth, perhaps adopts the thin blade that moves up and down to open 1-shaped open, perhaps opens the cross mouth by two blades successively, perhaps opens V font mouth with two blades of placing that tilt successively.Because the processing most convenient of round mouth, the easier control opening degree of depth is so round mouth is the optimal aperture form.

Characteristics of the present invention are that the inside that utilized microwave energy can penetrate heating object is rapidly heated it internally and ginkgo has the characteristics of a hard and fine and close shell and juicy kernel, the more important thing is that there is a cavity that is full of air ginkgo pulp inside, when we use the instantaneous heating of microwave, the airtight shell of ginkgo is just as a pressure cooker, it is rich in the kernel of moisture and cavity that kernel inside is full of air under the effect of microwave energy, moment produces the steam of HTHP, at this moment the opening on the shell of Semen Ginkgo just looks like the pressure release mouth on the pressure cooker, when the HTHP air of instantaneous expansion when this little opening excretes, also just eject under the extruding at high pressure draught at the core bud of cavity the inside, meanwhile kernel shrinks in pressure release moment again after the high pressure instantaneous expansion, make it be close to that film clothing on the kernel is also whole thereupon to come off with kernel, through above-mentioned simply and effectively processing method, just can reach the multiple eating effect, that is: can prevent the nut blast when having baked kernel with microwave is instantaneous again, the bitter taste core bud that also makes simultaneously the food containing gingko almond the inside influence local flavor is removed, people only need the ginkgo of the present invention's processing is put into micro-wave oven when edible, firepower transfers to low-grade heating and gets final product for 20 seconds, one pinch gently along the position of opening with hand then, shell benevolence is just separated gently, it is glutinous that people just can have mouthfeel perfume (or spice), the leisure food of implication of endless appeal.In a word, the present invention can take off the film clothing on the kernel, and kernel core bud is removed, and the instantaneous baking of microwave is not exploded, and can make the eater remove shell very easily, is convenient to the millwork batch process.

In addition, the present invention is very different with the way of the shell of ginkgo being peeled off half, this method only needs have an end of core bud to open one the opening that just is deep into core bud place (general dark 1～2mm) ginkgo, the too little purpose that does not then reach opening then can't produce the required pressure of blast extrusion die bud too greatly.
