Abstract

The invention discloses a technology for extracting edible silkworm chrysalis protein powder without chrysalis odor and salt. It includes the processes of defatting, grinding and separating, protein extracting, centrifugal separation, concentration, deodorization, drying, etc. And the centrifugal separation is to pump the protein extract into a DBD type disc centrifuge to obtain the protein extract. The deodorization is carried out by adopting conventional vacuum deodorization and H2O2A method combining oxidation deodorization. By adopting the method, the product quality is high, the protein content is higher than 7%, the ash content is lower than 4.5%, and the fat content is lower than 2%. The auxiliary materials (NaOH and water) can be recycled, basically has no loss, reduces the comprehensive cost and has good deodorization effect. The selected equipment is suitable for mass continuous production, and the requirements of factory equipment and fire and explosion protection are low.

Description

The extraction process of the smelly salt-free edible silkworm chrysalis silkworm white powder of no pupa
The present invention relates to the extraction process of pupa albumen powder, especially relate to the extraction process of the smelly salt-free edible pupa albumen powder of no pupa.
Producing the comparatively advanced method of pupa albumen powder at present is " with the method for extraction of chrysalis stinkingless protein with organic solvent " (Chinese patent, 861015118.Int.C14.C07K.3102, applying date 1986.7.4, authorize a day 1990.2.28), its technical process is: bright pupa → add water fragmentation → sieve and remove slag → drying → degreasing → deodorizing → drying → product.The protein content that this technology is produced is not less than 80%, and ash is not more than 6%, and lipid content is not more than 5%, and water content is not more than 5%.
The deficiency that this technology exists is: (1) adopts spraying drying earlier, adopts vacuum-drying again, and energy consumption is big, and vacuum-drying only is suitable for a small amount of continuous production; (2) utilize the low boiling point organic solvent precipitating proteins, and utilize this organic solvent to wash protein repeatedly with deodorizing, effect is not fairly obvious, and solvent consumption is big; (3) the ash content of coal height; (4) for guaranteeing that silkworm chrysalis is fresh, need build freezer to store the cost height.
The purpose of this invention is to provide a kind of extraction process that industrial mass production does not have the smelly salt-free edible pupa albumen powder of pupa that is suitable for.
Technical process: degreasing → defibrination separation → albumen extraction → centrifugation → concentrate → deodorizing → drying.
Degreasing: the silkworm chrysalis behind the filature is removed pelettes, contain in Nylon Bag, drop in the squeezing machine, utilize pressure to extrude pupal fat and moisture content, collect the oil-water mixture of extruding, the centrifugal pupal fat that gets.This method is removed 55% of fat approximately, as is dried pupa, then utilizes the pressure of spiral propeller, and pupal fat is pushed out.This method is removed fat 60%~70%.
Defibrination separates: the pupa after will extracting oil adds the water fragmentation, sieves to remove pupa skin pupa slag.
Albumen is extracted out: take the secondary extraction process, promptly for the first time use 0.5%NaOH, bath raio 1: 8 is heated 50~60 ℃, extracting 4 hours, incline clear liquid after, residue 2%NaOH, bath raio 1: 2 is heated 50~60 ℃, extracting is 2 hours again.Merge the extracting clear liquid twice, get protein extract.
Centrifugation: protein extract is pumped into DBD type disc centrifuge, utilize strong centrifugal force to isolate remaining fluid (merging) and remaining pupa skin pupa slag, obtain the pure protein Extract with degreasing process fluid.
Concentrate: utilize UF membrane concentration pure protein Extract.Ultra-filtration membrane is selected polysulfones for use, working pressure 5~6atm, 50~55 ℃ of service temperatures.Utilize ultra-filtration membrane can hold back the protein of macromolecule and can not hold back micromolecular NaOH, H 2The characteristic of O constantly adds dilution water, can remove NaOH and most of water fully, obtains protein concentrate Extract and UF and sees through liquid.UF is high through whey BOD in the liquid, the formation of abandoning is polluted, and (account for whey 1%) and lactose (account for whey 4~5%) have been wasted and have had high nutritive value and multi-purpose quality protein, therefore, make it again by the RO film, obtain RO concentrated solution and RO and see through liquid (promptly extremely rare alkali lye adds albumen as recycled water and extracts out in the operation).
Deodorizing: adopt traditional vacuum to drive smelly and H 2O 2The method that the oxidation deodorizing combines.UF protein concentrate Extract vacuum under 680~720mm mercury column negative pressure is driven smelly half an hour, and bubbling air adds the heavy H of 0.2~3% material 2O 2(30% content) stirs, and 20~30 ℃ of temperature controls, add an amount of H at oxidation deodorizing, sterilization half an hour 2O 2Lytic enzyme.The same RO concentrated solution of handling.
Dry: as to select spray-drier for use, 180~200 ℃ of inlet air temperature, 90~94 ℃ of temperature outs, spraying drying.
UF protein concentrate liquid is after deodorizing is handled, and spraying drying gets white to the smelly no-salt silkworm chrysalis protein powder of faint yellow no pupa.Protein content is no less than 87%, and fat is not more than 3%, and ash is no more than 1.5%.The RO concentrated solution is after deodorizing is handled, and spraying drying gets quality protein and lactose miscellany.
Compare with the method with extraction of chrysalis stinkingless protein with organic solvent, this technology has following salient feature:
1. quality product height.Protein content exceeds 7%, and ash low 4.5%.Lipid content low 2%.
2. silkworm chrysalis is only required not putrid and deteriorated getting final product, and need not build freezer and guarantee the fresh of raw material.
3. auxiliary material (NaOH and water) can be recycled after UF film and RO film, and is lossless substantially, and comprehensive cost descends.
4. good deodorization effect.The smelly composition of pupa is very complicated, it is generally acknowledged that this class material is lipid acid and proteolytic product.Because this technology removed fat in advance, the deodorizing operation adopts vacuum to drive smelly (with to utilize organic solvent to wash repeatedly with the de-odorised principle identical, all having utilized the easy volatile of stink) and H again simultaneously 2O 2The method that the oxidation deodorizing combines is held concurrently and is killed the bacterium that may bring in the production process, has eliminated hidden danger largely, and deodorizing effect is even more ideal.
5. selected equipment all is suitable for a large amount of continuous production.Factory building, equipment, fire-proof and explosion-proof require low.
And produce the silkworm chrysalis protein yield with membrane separation process and reach 50.3%, also improve, thereby can effectively utilize silkworm chrysalis protein, for large-scale developing and utilizing of silkworm chrysalis opened up wide prospect than 47.8% of organic solvent method.
