Abstract
The present invention relates to adsorbing lead, the cadmium that chelating method removes in flax protein, the present invention comprises the following steps：Take flax protein powder, adsorption reaction, solid-liquid separation, replace chelating, adjust pH, sterilizing, dehydration and drying and other steps.The present invention can synchronously reduce lead in flax protein, cadmium content effectively, and does not interfere with organoleptic quality and the nutritive value of flax protein.
Description
Technical field
The present invention relates to adsorbing lead, the cadmium that chelating method removes in flax protein, belong to processing of farm products field.
Background technology
Flax protein has good aminoacid composition and ratio, is a kind of excellent vegetable protein, has important utilization
It is worth.However, because industry, mining industry are to agriculture pollution, Caulis et Folium Lini heavy metal pollution problem progressively exposes.Lead, cadmium and Caulis et Folium Lini
Protein is combined in the form of complex, leads to heavy metal accumulation in flax protein so as to edible safety is affected.
Lead, cadmium can be enriched with vivo, serious harm health.Lead is had an effect and can be damaged with internal biomolecule
The systems such as evil reproduction, nerve, digestion, immunity, kidney, cardiovascular, affect growth promoter.Cadmium can cause connective after being absorbed by the body
Tissue injury, reproductive system dysfunction, injury of kidney, have teratogenesis and the harm such as carcinogenic, or even impact growth and intelligent development.
Content of the invention
It is an object of the invention to provide adsorbing lead, the cadmium that chelating method removes in flax protein, it is desirable to provide a kind of method letter
Just, the rational method of cost reduces lead, cadmium in flax protein, improves foodsafety.
Lead in absorption chelating method removal flax protein, cadmium, comprise the following steps：
(1) take flax protein powder double centner, add 920-940 kilogram of drinking water, mix；
(2) adsorption reaction：The sodium hydroxide being slowly added to 2.3-2.5mol/L adjusts serosity pH to 9.6-9.8, treats albumen
After all dissolving, add 3.5-3.7 kilogram of insoluble dietary fiber, mix, keep 3.2-3.4 hour, period at 44-46 DEG C
It is stirred continuously, mixing speed is 3600-3900 rev/min；
(3) solid-liquid separation：Carry out solid-liquid separation, remove insoluble solid, protein slurry carries out replacing chelating；
(4) replace chelating：Adjust serosity pH to 3.7-3.9 with the hydrochloric acid of 2.6-2.8mol/L, be slowly added to 4.0-4.2 thousand
Gram tartaric acid and 320-340 gram of zinc chloride, mix, and keep 3.1-3.3 hour at 44-46 DEG C, and period is stirred continuously, mixing speed
For 3800-4000 rev/min；
(5) adjust pH：The pH to 6.3-6.5 of flax protein serosity is adjusted in 20 minutes；
(6) sterilize, be dehydrated and be dried：Serosity carries out sterilization treatment, is then dehydrated, is dried, obtains flax protein product.
Wherein, insoluble dietary fiber is made up of cellulose and lignin, and both mass ratioes are 4:5, mean diameter is
920-940 mesh.
The present invention adopts sodium hydroxide to adjust pH it is ensured that needed for the insoluble dietary fiber Adsorption of Heavy Metals of particular fineness
Specific alkalescence condition, avoids the impact to flax protein finished product local flavor for the course of reaction simultaneously.Under specific pH, continuously stirred guarantee
Dietary fiber and flax protein are fully contacted reaction.Replace chelation stage, tartaric acid-hydrochloric acid compound system ensure that zinc ion
With the efficient competition chelating of cadmium, lead, metal target is replaced out, thus reach reducing lead, the effect of cadmium content further.
The present invention utilize particular fineness dietary fiber heavy metal adsorption, and zinc ion to cadmium, lead competing
Striving property replaces chelating, lead, cadmium content in synchronous reduction solution.The method operating condition is gentle, can operate continuously, and does not affect to produce
Product mouthfeel, profile and nutritional labeling.
Specific embodiment
Describe in more detail the present invention below by specific embodiment.
Embodiment 1
(1) take flax protein powder double centner, add 9940 kilograms of drinking waters, mix；(2) adsorption reaction：It is slowly added to
The sodium hydroxide of 2.3mol/L adjusts serosity pH to 9.6, after albumen all dissolves, adds 3.5 kilograms of insoluble dietary fibers
(cellulose and lignin quality are than for 4:5, mean diameter is 920 mesh), mix, keep 3.4 hours at 46 DEG C, period is continuous
Stirring, mixing speed is 3900 revs/min；(3) solid-liquid separation：Carry out solid-liquid separation, remove insoluble solid, protein slurry enters
Row replaces chelating；(4) replace chelating：Adjust serosity pH to 3.7 with the hydrochloric acid of 2.8mol/L, be slowly added to 4.2 kilograms of tartaric acid
With 320 grams of zinc chloride, mix, keep 3.3 hours at 44 DEG C, period is stirred continuously, mixing speed is 3800 revs/min；(5) adjust
pH：The pH to 6.5 of flax protein serosity is adjusted in 20 minutes；(6) sterilize, be dehydrated and be dried：Serosity carries out sterilization treatment, so
It is dehydrated afterwards, is dried, obtain flax protein product.
Embodiment 2
(1) take flax protein powder double centner, add 9940 kilograms of drinking waters, mix；(2) adsorption reaction：It is slowly added to
The sodium hydroxide of 2.3mol/L adjusts serosity pH to 9.6, after albumen all dissolves, adds 3.5 kilograms of insoluble dietary fibers
(cellulose and lignin quality are than for 4:5, mean diameter is 920 mesh), mix, keep 3.4 hours at 46 DEG C, period is continuous
