Abstract

The invention discloses a method for preparing superfine nano-scale shrimp sauce and shrimp meal nutriment which can be absorbed and utilized by human bodies by performing secondary processing on the waste shrimp heads and dried shrimps in aquatic product processing. The method comprises the following steps of: preparing the superfine shrimp sauce with the granularity less than 1 micro from the cleaned shrimp heads and dried shrimps by boiling, primarily crushing, softening the shrimp shells, finely crushing and ultra-micro grinding and refining; and preparing instant dried shrimp powder with the moisture content less than 7 percent through spray drying. The nano-scale product has smooth mouthfeel and delicious taste of fresh shrimps, and is particularly suitable to be used as a calcium supplement nutritional and health care food for the old and children.

Description

Produce the method for ultra-fine shrimp paste, shrimp med with shrimp head, dried small shrimp

Affiliated technical field

The present invention carries out the nano level shrimp paste that secondary operations becomes human body to absorb easily, the production method of shrimp med nutriment with discarded object shrimp head, dried small shrimp in the processing of aquatic products.

Background technology

China's seashore line length, the shrimp aquaculture field that from south to north, is distributing numerous in thousands of kilometers coastline and the inland lake.Add fishing for of the wild shrimp in ocean, nearly 1,000,000 tons shrimp output is arranged every year.Nearly half shrimp is wherein arranged in carrying out disposable processing of aquatic products, shrimp head, the dried small shrimp peeled off behind the peeled shrimp can only be as the low value additives of normal diet.Also there is a spot of shrimp after fermenting, to roughly grind into traditional shrimp sauce.But this seed shrimp sauce is very coarse, has only utilized the protein fermentation in the remaining meat in the shrimp head to generate the delicate flavour product.And the nutritive value of shrimp head and dried small shrimp itself can not be the human body utilization.Contain 40% protein, 30% calcium and 30% chitin in the shrimp housing.These materials all are high-grade human nutrition things.But because its crust is too hard, the digestive system of bigger coarse granule human body can't utilize, if it is crushed to nanoscale, then human body can directly see through the intestines wall and absorb.

Summary of the invention

The present invention be directed to remaining shrimp head, the dried small shrimp of above-mentioned shrimp products after disposable processing does the secondary deep processing and produces high-grade human nutrition health product.Shrimp head, dried small shrimp that delicate flavour is high are done superfine grinding, with its crushing grinding to particle diameter less than micron order.The shrimp paste of producing thus, the absorption by human body degree has improved widely.Again the water evaporates in the shrimp paste of producing being fallen to produce instant shrimp med can make its shelf-life prolong.Putting into soup or boiling water when edible drinks after molten all very convenient.The technical scheme that production shrimp paste, shrimp med of the present invention are adopted is: the first step, and the shrimp head, the dried small shrimp that clean up are put into pot add the salt of water and total amount 2% and a small amount of spice and heating and boil.Second step, pull the shrimp head, the dried small shrimp that boil out and put into and carry out preliminary fragmentation in the pulverizer, make the granularity of shrimp head, dried small shrimp be less than 5 millimeters.In the 3rd step, preliminary broken shrimp head, dried small shrimp are placed container.Again the shrimp water that boils that is cooled to 60 degree Celsius is injected wherein, in container, inject HCl solution simultaneously.After stirring, detect acidity-basicity ph value and will reach 4 to 5, and placed 10 to 24 hours.The 4th step, the shrimp head after soaking, dried small shrimp are put into colloid mill together with immersion water make further fine crushing, make the granularity that forms shrimp paste reach 100 to 200 microns.In grinding, add an amount of Na ₂CO ₃, the pH value that makes shrimp paste is 6.8 to 7.5 scope.The 5th step, shrimp paste to be put into gear ultramicro-grinder carry out meticulous grinding, the granularity that makes shrimp paste is less than 1 micron.The anticorrisive agent that adds gross weight 0.1% when grinding.As the shrimp paste sterilization of can bottling.In the 6th step, the shrimp paste that lappingout is ground is sent into and is produced moisture content after the heated-air drying of spraying in the spray dryer less than 7% dried shrimp med.Can preserve for a long time after the packing.

The advantage of shrimp paste of the present invention, shrimp med production method is: 1, without fermentation, make shrimp paste, shrimp med keep the bright fragrance of former shrimp.2, shrimp head, the dried small shrimp of low value are done ultra micro refinement processing after, become the high-grade nutrient and healthcare products that human body can absorb, economic worth has improved several times.

The specific embodiment

Provide further specifying of method of producing shrimp paste, shrimp med with shrimp head, dried small shrimp of the present invention below in conjunction with description to embodiment.

Shrimp head, dried small shrimp that clean water product processing factory shelled behind the peeled shrimp are put into pot, and add a spot of water heating and boil.The salt and a small amount of spice that in the process of boiling, add gross weight 2%.Shrimp head, the dried small shrimp that boils pulled out in the input disintegrating machine of back and done preliminary pulverizing.Shrimp after a pulverizing granularity is less than 5 millimeters.At the beginning of a broken shrimp dried small shrimp put into container, implantation temperature reduce to 60 ℃ boil shrimp water, and pour HCl solution into, the detection acidity-basicity ph value will reach 4 to 5 through stirring after.Deposited 10 to 24 hours, HCl can with the calcium generation chemical reaction in the shrimp shell.Make calcium and Cl in a part of shrimp shell ^-Ion generates the CaCl of taste hardship ₂Shrimp shell deliquescing this moment, mechanical strength have reduced widely and have been beneficial to crushing grinding refinement further.After this shrimp head that softened, dried small shrimp are sent into colloid mill together with immersion water and carry out the refinement fragmentation.Through producing granularity after the grinding of colloid mill is 100 to 200 microns shrimp paste.In order to eliminate the CaCl of bitter taste in the shrimp paste ₂Must in shrimp paste, add minor N a ₂CO ₃Come and CaCl ₂Carry out displacement reaction.The result of reflection has generated NaCl and CaCO ₃NaCl is a due one-tenth flavor composition in the sauce.Be the simultaneous chemical reactant CaCO of superfine grinding process at grinder ₃Just become the nanoscale composition.Nano level CaCO ₃Can be become fabulous calcium replenishing material by the intestinal absorption of human body.Na ₂CO ₃The acidity-basicity ph value that what of addition should be controlled at shrimp paste is in 6.8 to 7.5 the scope.Mouth is tasted and can not be felt bitter.The shrimp paste granularity of this moment is still thick for absorption of human body, therefore needs further to grind refinement.Is these shrimp paste and gross weight that 0.1% anticorrisive agent injects gear ultramicro-grinder and does further to grind refinement.Shrimp paste particle in the gear type grinder is refine to be lower than 1 micron and can to stop after promptly entering nanoscale grinding and discharge grinder and send into bottling disinfection operation.The shrimp paste mouthfeel of so producing is satiny to have the deliciousness of bright shrimp also to be beneficial to absorption by human body again.If make shrimp med, shrimp paste can be sent into and carry out drying in the spray dryer.Final products are moisture content less than 7% instant shrimp med.Will send into after the fresh shrimp paste branch that moisture content is high is packed in the vial and carry out sterilization treatment in the high-temperature steam sterilization jar, vapor (steam) temperature should be greater than 110 degree.Feng Zhuan the shrimp paste shelf-life can be longer like this.Shrimp paste of the present invention, shrimp med production method are suitable for the making of blachan and crab sauce and powder too.
