Abstract
The present invention relates to a method for extracting pearl liquor from Ma's pearl shells. Cleaned pearl shells are soaked in acetic acid and softened, and pure pearl slices are obtained by mechanical self-grinding; the pure pearl slices are baked, pulverized, ground and heated for hydrolysis by sulfuric acid, calcium carbonate or lime milk is added for neutralization, and pearl original liquid is obtained by vacuum concentration as well as decolorization and trash extraction by active carbon. When the method of the present invention is used, the peeling of pearl shells is complete and clean, and the recovery rate is as high as over 80%. The prepared pearl oral liquor has good mouth feeding without abnormal tastes of bitterness, saltiness or acerbity, and is a good product for medical care.
Description
The present invention relates to a kind of method of from the Ma Shi mother pearl shellfish, extracting Margarita liquid.Margarita liquid belongs to a kind of healthcare products.
At present, the method for extracting Margarita liquid in the production is that emery wheel grinds off the useless skin of Ma Shi mother pearl shellfish by hand, uses hydrochloric acid hydrolysis then, and remove impurity, deacidification obtain Margarita liquid.Existing method exists following shortcoming: 1, manual operations, production efficiency is low.2, use grinder buffing, can only polish natural, individual big Ma Shi mother pearl shellfish are for the utilization of then can't polishing of artificial cultivation, less mother pearl shellfish.3, it is unclean to remove female shellfish skin with the method for artificial polishing, makes Margarita layer powder content low (the chloro acid content only is 1.93%).4, produce Margarita liquid with the hydrochloric acid hydrolysis method, the response rate is not high, generally 20～50%, and remove impurity, deacidification difficulty, the Margarita liquid bitter in the mouth that obtains, salty, puckery, mouthfeel is bad, should not directly take, polygamy is with other Chinese herbal medicine extract, a large amount of saccharide or sweeting agent, to improve mouthfeel and to cover precipitation.
The object of the present invention is to provide a kind of useless shell that can peel off the Ma Shi mother pearl shellfish complete, neatly, can realize the extracting method of the Margarita liquid that mechanization is produced, that flow process is short, cost is low, the response rate is high, the acquisition mouthfeel is good.
Key problem in technology of the present invention is with the Ma Shi mother pearl shellfish of cleaning, to soak down with acetic acid room temperature, treat outer softening, come off, again through mechanical autogenous grinding, the pure nacreous layer slice that obtains, drying, pulverizing, levigate obtain Pearl, with described Pearl sulphuric acid heating hydrolysis, hydrolyzate neutralizes with calcium carbonate or lime cream, vacuum concentration is used activated carbon decolorizing, remove impurity at last, obtains pearl crude liquid.
Specifically, the present invention is that with the acetic acid of 1.5～8mol/L concentration, solid-to-liquid ratio is 1: 3～6 with the Ma Shi mother pearl shellfish after cleaning with clear water, room temperature soaked 10～30 hours down, make the useless skin of Ma Shi mother pearl shellfish softening, and come off, pass through the autogenous grinding method of machinery again from nacreous layer, useless skin is peeled off with nacreous layer slice fully, obtain the nacreous layer slice that a kind of fineness is good, size is complete, clean, drying, pulverizing, fine grinding more promptly gets purified Margarita layer powder.
With above-mentioned purified Margarita layer powder, to decompose with sulphuric acid, dissolving finishes, and 100～150 ℃ oil bath, steam jacket heating, perhaps uses other method heating hydrolysis 18～36 hours, hydrolyzed solution acidity C (H then
2SO
4)=2.5～5.5mol/L, the hydrolyzate of gained is through calcium carbonate or lime cream (crossing 110 μ m sieve), vacuum concentration is filtered in PH=5～7.5 that neutralize, reuse 1～5% (weight) decolorization and impurity removal by active carbon is handled, promptly obtain the Margarita concentrated solution, use distilled water diluting, be mixed with stock solution type pearl oral liquid, pass through fill, sterilizing again, finished product packing.
Extract Margarita liquid compared with the prior art by method of the present invention, have following six big advantages: 1, the Ma Shi mother pearl shellfish shell of peeling off through acetic acid is peeled off complete, clean, the nacreous layer slice fineness that obtains is good, contains effective ingredient height such as aminoacid, and content reaches 2.534%.2, the present invention is not only applicable to from natural individual big Margarita, is more suitable for can making full use of various resources in extract Margarita liquid from the Xiao Bei of artificial cultivation.3, the present invention makes and peels off Margarita realization mechanization large-scale industrial production.4, use extracting method of the present invention, its flow process is short, technology is simple, the response rate is up to more than 80%.5, the pearl oral liquid of making by method of the present invention need not add any Chinese herbal medicine, antiseptic, pigment and flavoring agent, and mouthfeel is good.Not only can take orally, can also external.For oral administration have heat-clearing and toxic substances removing, effects such as the arresting convulsion of calming the nerves, convergence granulation promoting, the guarantor's spring of preserving youthful looks; External can bactericidal antiphlogistic, removes beauty functions such as miliaria, facial skin ulcer, " comedo ".6, the pearl oral liquid of producing by the present invention detects through Guangxi district health and epidemic prevention department, meets GB4789-84, GB5009-85 inspection for food hygiene standard; Margarita liquid contains aminoacid 27.54mg/ml.
Embodiment 1
The 3kg Ma Shi Margarita Xiao Bei (culturing shellfish) that cleans silt is poured in the alimentary acetic acid mixed liquor that fills 9 the lucid yang sending up water and 3 liter 94%, and room temperature soaked 12 hours down, picked up, and placed φ 280 * 290mm ceramic whiteware jar rolling autogenous grinding 1～2 hour.Pour out, clear water cleans, and can obtain the good nacreous layer slice of complete fineness, dries, pulverizes, sieves, and can get Margarita layer powder 1053 grams of-110 μ m.
Above-mentioned 750 gram Margarita layer powder are added in the 2000ml distilled water, slowly add the 1000ml concentrated sulphuric acid, and then, be neutralized to PH=7.5 with lime cream (110 μ m sieved) after the hydrolysis 100～150 ℃ of oil bath pan internal heating hydrolysis 24～36 hours.Filter,, then 2% active carbon is further decoloured, remove impurity to 1/7th to 1/10th of original volume through vacuum concentration, can obtain to contain free amino acid is 27, the pearl crude liquid 0.576L of 54mg/ml, the response rate 83.5%.Taste and sweet mouthfeel, there is not the transparent stock solution of bitter, no puckery, free from extraneous odour.
Embodiment 2
213kg Ma Shi mother pearl shellfish after washing is soaked in 1000 liters and contains in acetate concentration C (HAC)=3.17mol/L solution, and room temperature steeped 24 hours down, placed the autogenous tumbling mill autogenous grinding to peel off, and powder is beaten in oven dry, obtains-110 μ m Margarita layer powder 70.79kg.
In 80 liters of distilled water, add 42.5 liters of analytical pure sulfuric acids, stir down, slowly add 40 kilograms of above-mentioned Margarita layer powder, hydrolyzed solution acidity C (H
2SO
4)=4.25mol/L.Use the steam jacket mode of heating 120～135 ℃ of following hydrolysis 24 hours then.Hydrolyzed solution through calcium carbonate neutralize PH=6.0, vacuum concentration to 33 rises volume again, adds 2.5% (weight) activated carbon decolorizing, remove impurity, obtains containing free amino acid and be 32.3 liters of the pearl crude liquids of 25.67mg/ml.Overall recovery 81.8%.Mouthfeel is equally good with example 1.
