Abstract
A process for preparing shrimp protein powder includes pretreating, breaking, filtering, washing separation, spray drying, pulverizing and separation. The said shrimp protein powder has high content of nutrients.
Description
The present invention relates to the technology of ocean water product deep processing, particularly extract the processing technology of protein from salted shrimp gravy.
The processing method of salted shrimp gravy mainly contains following several form at present:
(1) centrifugal separation utilizing centrifuge to separate after the salted shrimp gravy pulverizing slurrying, makes shrimp podwer to upper strata slurry oven dry.But this content of ashes is still more than 30%.
(2) saline floatation method, salted shrimp gravy pulverized slurrying after, add NaCl and make brine strength reach 14 ° of Be to make the shrimp come-up, sediment settlement and separating.The content of ashes of gained shrimp podwer is more than 32%.
(3) the molten extraction method of alkali adds 5%NaOH solution to the slurry of the salted shrimp gravy after pulverizing and boils, and adds HCl and transfers pH value about 3, remove sediment dry shrimp podwer.Though this method content of ashes reduces, the yield rate of shrimp podwer also reduces.
Purpose of the present invention is exactly the content of ashes height that exists at existing processing technology, and the defective that yield rate is low provides a kind of processing technology economical and practical, yield rate height, and the high processing technology of finished product nutrient composition content.
A kind of technology of the present invention comprises following technological process composition:
(1) salted shrimp gravy is carried out preliminary treatment, salted shrimp gravy is cleaned with clear water, removing impurity such as weeds, halogen fly, halogen maggot with floating method, is that the pure bittern of 15Be '-18Be ' takes suspension method to remove materials such as the external silt of salted shrimp gravy with content then, after the cleaning and filtering clean salted shrimp gravy;
(2) clean salted shrimp gravy is pulverized, extrude unnecessary juice with upper filter screen, make salted shrimp gravy magma, make the active ingredient of magma be the colloid shape with 50 orders;
(3) remove silt with centrifugal separation after, the pure slurry of salted shrimp gravy, utilize the isoelectric point principle to adjust pH value between 5-7, make the colloid condense precipitation, centrifugation then with clear water washing two to three times, is removed soluble impurity, promptly gets the salted shrimp gravy refined stock;
(4) liquid-solid ratio that will make with extra care the salted shrimp gravy slurry is regulated suitably, and after the spray-drying, dry temperature is controlled between the 100-125 degree, separates once more and pulverizes, and further removes impurity, promptly gets edible salted shrimp protein powder.
Another kind of technology of the present invention comprises following technological process composition:
(1) salted shrimp gravy being carried out preliminary treatment, salted shrimp gravy is cleaned with clear water, remove impurity such as weeds, halogen fly, halogen maggot with floating method, is that the pure bittern of 15Be '-18Be ' takes suspension method to remove materials such as the external silt of salted shrimp gravy with content then, gets clean salted shrimp gravy after the cleaning and filtering;
(2) clean salted shrimp gravy is become dried shrimp med or dried prawn slice with the hot blast convection drying of 60-125 degree;
(3) dried salted shrimp gravy is ground into 180-250 purpose dry powder;
(4) with the shrimp podwer of drying hair-dryer removing impurities, this process can once be finished, and also wind separates repeatedly.
The salted shrimp protein powder of taking above-mentioned technological process to make reaches very high technical indicator: protein 60%; Fat 15%; Moisture is not more than 5%; Ash content (containing not capacitive of chitin) is not more than 12%; Inorganic arsenic is not more than 1 mg/kg.But the product output capacity is up to 1 kilogram of edible salted shrimp protein powder of per 17 kilograms of fresh and alive salted shrimp gravy outputs simultaneously.
Be described further below in conjunction with embodiment.
Embodiment 1:
At first, salted shrimp gravy is carried out preliminary treatment.Salted shrimp gravy is cleaned with clear water, remove impurity such as weeds, halogen fly, halogen maggot with floating method, be concentrated to the pure bittern immersion that 15Be '-18Be ' content obtains with natural bittern then, take suspension method to remove materials such as the external silt of salted shrimp gravy, get clean salted shrimp gravy after the cleaning and filtering, clean salted shrimp gravy is heat-treated with steam or hot water,, make protein coagulating to reduce inorganic salt content in the shrimp body;
Second step, with disintegrating machine, colloid mill clean salted shrimp gravy is pulverized, extrude unnecessary juice with 50 orders with upper filter screen, make salted shrimp gravy magma, make the active ingredient of magma be the colloid shape;
The 3rd step, remove silt with centrifugal separation after, the pure slurry of salted shrimp gravy, utilize the isoelectric point principle to adjust pH value between 5-7, make the colloid condense precipitation, centrifugation then with clear water washing two to three times, is removed soluble impurity, promptly gets the salted shrimp gravy refined stock;
The 4th step, the liquid-solid ratio of refining salted shrimp gravy slurry to be regulated suitably, after the spray-drying, dry temperature is controlled between the 60-125 degree, separates once more and pulverizes, and further removes impurity, promptly gets edible salted shrimp protein powder.
Embodiment 2:
The first step obtains clean salted shrimp gravy according to the same quadrat method of embodiment 1;
In second step, clean salted shrimp gravy is become dried shrimp med or dried prawn slice with the hot blast convection drying of 60-125 degree;
In the 3rd step, dried salted shrimp gravy is ground into 180-250 purpose dry powder with pulverizer;
In the 4th step, with the shrimp podwer of drying hair-dryer removing impurities, this process can once be finished, and also wind separates repeatedly, and is clean up to salted shrimp gravy dry powder is separated.
