Abstract
The present invention relates to a kind of process for purification of edible plant ash alkali.Contain harmful arsenic, heavy metal and cyanide in the grey alkali that prior art is produced.Adopt the present invention can remove these harmful substances effectively, still keep the peculiar activity and the peculiar fragrance of existing grey alkali simultaneously.Technology of the present invention is simple, is easy to suitability for industrialized production, and resulting product meets the regulation of dietary alkali standard fully.
Description
The present invention discloses a kind of preparation method of alkaline addtives used for foods.It specifically is a kind of process for purification that contains potash, sodium carbonate, potassium chloride, sodium chloride and a spot of phosphatic plant ash alkali that is used for food.
Plant ash alkali is the China's western region, particularly Gansu province extensively edible a kind of basic food additive among the people.It is with the fluffy grass of the higher drought-enduring plant of salt content (water is fluffy and thorn is fluffy) frit of the fired grey black look slag shape that forms in pit furnace.In use, grey alkali is smashed, water boils, and its leachate is the grey buck of use among the people.This grey buck is yellowish-brown, shows strong basicity, and main component is sodium carbonate, potash, sodium chloride, potassium chloride and a spot of phosphate.Add the ash charge buck in right amount in dough after, dough is easy to be drawn as slice, also has special fragrance simultaneously.Find that through assay with the grey alkali that prior art is made, the content of arsenic and heavy metal substantially exceeds the allowed band of dietary alkali national standard defined in its leachate.In check, also find simultaneously, also contain higher potassium cyanide in the grey alkali leaching liquor.Below be arsenic in the grey alkali, the correction data of heavy metal and potassium cyanide measured result and dietary alkali national standard (PPM of unit)
Project arsenic heavy metal cyanide
Ash alkali 36.1 34.3 130
Dietary alkali national standard＜2＜10 can't check
（GB1886-80）
Obviously, the grey alkali that uses prior art to produce is harmful to health.
The purpose of this invention is to provide a kind of grey alkali refining method, to remove the harmful substances such as arsenic, heavy metal and potassium cyanide that contained in the existing grey alkali, its refined products of while still can remain with existing grey alkali can make dough be easy to the characteristics of drawing-down and the advantage of distinctive fragrance.
The grey alkali fusion piece that the present invention produces with prior art is a raw material, after crushed, roasting is to remove the cyanide in the frit under oxidizing atmosphere, arsenic in the raw material is removed with the form volatilization of arsenic trioxide, in water, leach then, effective ingredient is dissolved in the water, and insoluble sludge is separated, add again hydrogen or alkali metal sulphide as precipitating reagent to remove the heavy metal in the leachate, thus the aqueous solution of gained promptly become can be edible basic additive.As further processing, the solution evaporation drying can be formed crystalline solid.
Detailed method of the present invention is as follows: at first existing grey alkali fusion piece is pulverized, its granularity is not more than 2 millimeters, places stove to carry out roasting then, should control furnace atmosphere in the roasting, make it to keep oxidizing atmosphere, sintering temperature is 200～800 ℃, and the time was advisable at 0.5～3 hour.Then material after the roasting is put in the water and leached.Behind appropriate time, in leaching liquid, add hydrogen or alkali metal sulphide, filter after leaving standstill, sediment is separated with the method for filtering with solution.So far the transparent colourless solution that obtains can directly use, also can carry out evaporation drying again, to obtain the solid product of crystallization.Practice shows that precipitating reagent can adopt hydrogen sulfide, potassium sulfide, vulcanized sodium or other alkali metal sulphide.Addition is 2～10% of a highly finished product solid amount.
The analysis result of handling grey alkali gained highly finished product with the present invention is as follows: (PPM of unit)
Arsenic, 0.41; Heavy metal, 8; Potassium cyanide, do not detect
This shows that the effect that the present invention removes harmful substance in the grey alkali is significant.And in the use experiment of reality, show that the highly finished product that obtained have kept existing grey alkali can make dough be easy to the characteristics of drawing-down and the advantage of distinctive fragrance fully.In addition, no matter be the solution that directly obtains or be colourless transparent liquid, rather than the yellowish-brown liquid of existing grey buck with the molten solution of crystallization body weight, so also health more.The present invention also has the advantage that technology is simple, be easy to suitability for industrialized production.
A most preferred embodiment of the present invention below is provided.
Enchashment has grey alkali 1000 grams, and crushing screening, mesh size are 2 millimeters.Roasting is one hour under 500 ℃ of oxidizing atmospheres.The scaling loss amount is about one of percentage.With after the 1200 ml tap waters leachings, concentration is 25%(W) 1000 milliliters of clear liquids.Add vulcanized sodium 5～7.5 grams, quite 2～3% of the highly finished product solid amount, filter after leaving standstill a few hours, promptly get colourless transparent liquid, this liquid is carried out promptly getting after the evaporation drying processing product of white crystals body.
Claims (3)
1, a kind of process for purification of edible alkalinity additive, in pit furnace, be fired into frit shape ash alkali with the higher drought-enduring plant of salt content such as fluffy grass, it is characterized in that roasting in the broken rearmounted oxidizing atmosphere of grey ground caustic, use water extraction then, in leaching liquid, add hydrogen or alkali metal sulphide precipitating reagent, after staticly settling, filter the aqueous solution that obtains edible basic additive, maybe this aqueous solution is handled through evaporation, drying, obtain crystalline solid.
2, method according to claim 1 is characterized in that grey ground caustic particle degree less than 2 millimeters, and sintering temperature is 200～800 ℃, and the time is 0.5～3 hour, and the precipitating reagent addition is 2～10% of a product solids total amount
3, method according to claim 1 and 2 is characterized in that precipitating reagent is a vulcanized sodium, and its addition is 2～7% of a product solids total amount
