Abstract
The invention relates to a method for synchronously reducing the contents of arsenic and copper in walnut protein. The method disclosed by the invention comprises the following steps of taking walnut protein powder, performing pulp blending, performing substitution and chelating, performing an adsorption reaction, performing solid-liquid separation, performing conditioning, performing sterilization, performing dehydration, performing drying and the like. According to the method disclosed by the invention, the contents of the arsenic and the copper in the walnut protein can be effectively and synchronously reduced, and besides, the feeling quality and the nutrient value of the walnut protein cannot be influenced.
Description
Technical field
The present invention relates to a kind of synchronization reduces arsenic, the method for copper content in walnut protein, belong to processing of farm products field.
Background technology
Walnut protein has good aminoacid composition and ratio, and digestibility is high, is a kind of excellent vegetable protein, has
Important value.Recently as the development of industry, mining industry, heavy metal pollution problem progressively exposes.Arsenic, copper are attached to
Walnut protein, leads to the edible safety of walnut protein to be affected.After enrichment arsenic, the protein of copper are eaten, can give birth to
Enrichment, serious harm health in object.
Content of the invention
The present invention is intended to provide a kind of method is easy, the rational method of cost reduces arsenic in walnut protein, copper content, carry
High edible safety.
Arsenic, the method for copper in a kind of synchronous reduction walnut protein, comprise the following steps：
(1) take Walnut protein powder double centner, add 940-960 kilogram of drinking water, mix；
(2) replace chelating：Add 3.4-3.6 kilogram of malic acid, then use the hydrochloric acid of 2.8-3.0mol/L to adjust serosity pH
To 3.2-3.4, add 300-320 gram of zinc chloride, mix, at 50-52 DEG C, keep 3.2-3.4 hour, period is stirred continuously, stirring
Speed is 4200-4400 rev/min；
(3) adsorption reaction：Add 3.4-3.6 kilogram of cellulose toward in walnut protein serosity, at 52-54 DEG C, stir 50-52
Minute, mixing speed is 4600-4800 rev/min；
(4) solid-liquid separation：Carry out solid-liquid separation, remove insoluble solid；
(5) quenched：The pH to 6.4-6.6 of walnut protein serosity is adjusted in 15 minutes；
(6) sterilize, be dehydrated and be dried：Serosity carries out sterilization treatment, is then dehydrated, is dried, obtains product.
Wherein, cellulose is Microcrystalline Cellulose, and mean diameter is 320-340 mesh.
The present invention adopts malic acid-hydrochloric acid compound system, that is, add salt acid for adjusting pH to ensure malic acid chelating heavy metal institute
The specific acid condition needing, avoids excessively adding the impact to walnut protein finished product local flavor for the malic acid simultaneously.Under specific pH, no
Disconnected stirring ensure that malic acid and walnut protein are fully contacted reaction, and zinc ion is chelated with the competition of arsenic, copper.In this shape
Under state, add the Microcrystalline Cellulose of particular fineness, can efficiently target heavy metal and unnecessary zinc ion be adsorbed, from
And reach synchronous reduction arsenic, the effect of copper content.
The present invention utilizes zinc ion under specific environment to replace chelation to arsenic, the competitive of copper, and specified particle diameter is micro-
The adsorption of crystalline cellulose；By both synergistic functions, the synchronous arsenic reducing in solution, copper content.The method is grasped
Make mild condition, can operate continuously, and do not affect products taste and nutritional labeling.
Specific embodiment
Describe in more detail the present invention below by specific embodiment.
Embodiment 1
(1) take Walnut protein powder double centner, add 960 kilograms of drinking waters, mix；(2) replace chelating：Add 3.6 kilograms
Malic acid, then uses the hydrochloric acid of 3.0mol/L to adjust serosity pH to 3.4, adds 320 grams of zinc chloride, mix, keep 3.4 at 52 DEG C
Hour, period is stirred continuously, and mixing speed is 4400 revs/min；(3) adsorption reaction：3.6 thousand are added toward in walnut protein serosity
Gram Microcrystalline Cellulose (mean diameter is 340 mesh), stirs 50 minutes at 52 DEG C, mixing speed is 4800 revs/min；(4) solid-liquid
Separate：Carry out solid-liquid separation, remove insoluble solid；(5) quenched：The pH to 6.5 of walnut protein serosity is adjusted in 15 minutes；
(6) sterilize, be dehydrated and be dried：Serosity carries out sterilization treatment, is then dehydrated, is dried, obtains product.
Embodiment 2
(1) take Walnut protein powder double centner, add 960 kilograms of drinking waters, mix；(2) replace chelating：Add 3.6 kilograms
Malic acid, then uses the hydrochloric acid of 3.0mol/L to adjust serosity pH to 3.4, adds 320 grams of zinc chloride, mix, keep 3.4 at 52 DEG C
Hour, period is stirred continuously, and mixing speed is 4400 revs/min；(3) quenched：Walnut protein serosity is adjusted in 15 minutes
PH to 6.5；(4) sterilize, be dehydrated and be dried：Serosity carries out sterilization treatment, is then dehydrated, is dried, obtains product.
Embodiment 3
(1) take Walnut protein powder double centner, add 960 kilograms of drinking waters, mix；(2) chelate：Add 3.6 kilograms of Fructus Mali pumilaes
Acid, then uses the hydrochloric acid of 3.0mol/L to adjust serosity pH to 3.4, keeps 3.4 hours, period is stirred continuously at 52 DEG C, stirring speed
Spend for 4400 revs/min；(3) quenched：The pH to 6.5 of walnut protein serosity is adjusted in 15 minutes；(4) sterilize, be dehydrated and dry
Dry：Serosity carries out sterilization treatment, is then dehydrated, is dried, obtains product.
The effect analyses of different embodiments：
Note：The score value of organoleptic quality is higher, represents that taste is better
Compared with embodiment 2,3, using the embodiment 1 of present invention process, its arsenic, copper content are down to 0.028mg/ respectively
kg、0.071mg/kg；And the organoleptic quality of embodiment 1 product is basically identical with embodiment 2,3.
The present invention carries out replacing chelating using zinc ion in certain circumstances, and arsenic, copper content decline；Continue fine using crystallite
After dimension element is adsorbed, the arsenic of product, copper content reduce further it is seen that zinc replaces chelating and cellulose adsorption has collaborative increasing
Effect acts on.
