Description

A kind of enzymolysis and dry method of preparing ginkgo crystalline substance of spraying applied
Technical field
The present invention relates to a kind of enzymolysis and dry method of preparing ginkgo crystalline substance of spraying applied.
Background technology
The additive side effect adopting in current ginkgo processing method is larger, then can not be by checking while exporting to the countries such as Japan, Korea S and Taiwan, and the Semen Ginkgo of producing surface can cover rear oxidation layer, and mouthfeel is poor.
Summary of the invention
The invention provides a kind of enzymolysis and dry method of preparing ginkgo crystalline substance of spraying applied, the surperficial non-oxidation layer of the Semen Ginkgo that it makes, mouthfeel is good, and additive side effect is little.
The present invention has adopted following technical scheme: a kind of enzymolysis and dry method of preparing ginkgo crystalline substance of spraying applied, and it comprises the following steps: step 1, raw material is selected: select, without going mouldy, being raw material without the ginkgo of hard-core, to adopt clear water rinsing to remove the rotten fruit of hard-core; Step 2, precooks: the ginkgo after cleaning is carried out to the processing of precooking of 20 minutes in boiling water; Step 3, shelling, peel and remove inner core: the ginkgo after treatment of precooking is while hot poured into and in rejuvenator, carries out sloughing shell after fragmentation and obtain Semen Ginkgo, then decortication, then removes the inner core of Semen Ginkgo with cutter, finally with clear water by Semen Ginkgo rinsing 2~3 times, thoroughly remove broken inner core; Step 4, drops into the benevolence lobe of Semen Ginkgo after processing in step 3 in colour protecting liquid and soaks and protect look, and the benevolence lobe that protects the Semen Ginkgo after look is pulled out, uses clear water rinsing, again scalds and boils after boiling water, is finally soaked in feed liquid again; After finishing, immersion uses again clear water rinsing; Step 5, making beating, defibrination: first with grinding-wheel grinder corase grind, then use colloid mill fine grinding; Step 6, biological enzymolysis: first with beta-glucosidase, the slurry after levigate is carried out to enzymolysis for the first time, then carry out enzymolysis for the second time with AMS and α-protease; Step 7, homogeneous: the slurry after enzymolysis is carried out to double-stage homogenization processing with homogenizer, and the process of homogeneous processing is: adopt homogenizer to carry out homogeneous processing in the slurry after enzymolysis, double-stage homogenization pressure when homogeneous is 40MPa, and homogenizing temperature is at 60 ℃; Step 8, modulation: add batching sweet mellow wine, soybean protein isolate, maltodextrin, xanthans, vitamin E and stevioside in homogeneous slurry after treatment, heating, fully stirs and make solution suspendible; Step 9, spraying is dry: the slurries after enzymolysis and proper auxiliary materials are mixed to rear spraying and be dried; Step 10, sieves, packing, ware-house-in inspection, finished product: xeraphium sieves, and packing is surveyed sample the packed ginkgo crystalline substance after packing.
Ginkgo in described step 1 is ripe, fresh, and shell is milky, without mildew, without the ginkgo of disease and pest and machinery-free wound.Colour protecting liquid solution described in described step 4 is saline solution, and the concentration of saline solution is 0.01%, and the time that the benevolence lobe of Semen Ginkgo soaks in colour protecting liquid is 2 hours, and again scalding the time of boiling is 1 minute, and the time of soaking in feed liquid is 1 hour.Described step 4 feed liquid is that after being mixed by the cold water of 0.08% sodium Diacetate and 99.92%, configuration forms, and is food containing gingko almond: the mass ratio of water is 1: 2.5 when clear water rinsing.In described step 5, add a small amount of citric acid to be conducive to keep the flaxen color and luster of ginkgo nut when defibrination.In described step 6, the process of biological enzymolysis is: in the slurry after first levigate in step 6, add the beta-glucosidase separating in honey to carry out enzymolysis for the first time, the pH value obtaining after enzymolysis is 4.5~6.5, and then rise to 60 ℃ of left and right, insulation 15min, regulate again pH6.2~6.4, be warming up to 80 ℃, and then in the slurry after enzymolysis for the first time, add 1.0% AMS and α-protease of 0.25% to carry out enzymolysis for the second time, insulation 15min, then be warming up to 100 ℃, keep 5min, then add water to 5kg.The mass ratio that adds sweet mellow wine, soybean protein isolate, maltodextrin, xanthans, vitamin E and the stevioside of batching in described step 8 is 9: 3: 1: 1: 1: 1, be heated to 80 ℃, and fully stir and make solution suspendible, the solid content in solution approximately 20%.Described step 9, spraying is dry: 70~80 ℃ of 150 ℃ of the temperature of the air intake while being dried of spraying after the slurries after enzymolysis and proper auxiliary materials are mixed, the temperature of air draft.In described step 10, adopt 60 mesh sieves to sieve to xeraphium, moisture≤1.5% of finished product, packing, every bag of 10g, finally surveys sample the packed ginkgo crystalline substance after packing.
The present invention has following beneficial effect: adopt the ginkgo crystalline substance that makes of this method, not only surface color cadmium yellow, mouthfeel micro-sweet, smell is fragrant, without bitter taste, noxious material is thoroughly decomposed, and the additive side effect adopting is little.In process prepared by the present invention, need to remove the inner core of ginkgo, can avoid like this sweetness and bitterness taste, improve the quality of product.The present invention needs the ginkgo processing of precooking in the process of preparation, is so more conducive to the heat treatment of ginkgo.The present invention selects beta-glucosidase enzyme hydrolysis cyanogen glycoside, has thoroughly removed toxicity and bitter taste.Use AMS restriction endonuclease, it cuts arbitrarily α-Isosorbide-5-Nitrae glucoside bond from intramolecule, generates macromolecular amylin and compound sugar, prevents the aging of product put procedure, has kept excellent flavor.The present invention's dry key technology of spraying, product appearance, taste, granularity, dissolves linearly, and water content all reaches requirement.Xeraphium of the present invention is crossed 60 mesh sieves, packing, and every bag of 10g, convenient to use.The present invention is by stability study, and the long term test of the accelerated test of 6 months (relative temperature 75%, 40 ℃) and 18 months (relative temperature 60%, 25 ℃) determines that this product stablized in 24 months.
