Abstract
The invention discloses a kind of processing citric acid industry slag method of (comprising wheat bran, fecula).Promptly use E solvent soaking bacterium slag 6-12 hours, after filtering filter residue is made feed, filtrate is made edible brown pigment after the oven dry of high temperature evaporation concentrated filtrate, and its look rate is 37000EBC, and stable performance can be used foodstuffs industry and medicine industry.The feed of making contains higher protein.The present invention makes that puzzlement citric acid industry waste residue for many years---the bacterium slag becomes the edible brown pigment and the feed of high economic benefit, has both administered the three wastes, has obtained higher effect again.
Description
The present invention relates to a kind of method of handling citric acid industrial waste residue-bacterium slag.It is a kind of method of utilizing citric acid industrial waste residue to produce edible brown pigment and feed.
Edible brown pigment is the same with other food dye, and the method for producing is varied.Have plenty of from natural chromophorous plant and extract, as from plants such as black bean fruit, black glutinous rice, the red sage root, extracting.Has plenty of the saccharine material of utilization by ammonium salt process production; Or molasses are isolated sugar part back concentrating and separating and making by fermentation.These methods mainly all are higher industrial raw material and natural phant of the price of usefulness, thereby cost is higher.The method of utilizing the foodstuffs industry waste material to produce food dye is disclosed in a lot of for this reason documents.For example: methods such as " producing edible paste pigment (application number 88100743A) ", " producing edible paste pigment (88100741A) " with the wood sugar waste residue with sugar refinery alcohol waste residue.These utilize industrial waste to produce the method for edible brown pigment, have both solved problem of environmental pollution, have produced bigger economic benefit again.In citric acid production, the waste residue that is discharged mainly is to comprise black-koji mould and wheat bran, fecula in the bacterium slag, is the unsolved for many years difficult problem of puzzlement citric acid enterprise, has also therefore limited the lemon industrial expansion.If can make these waste residue liquids be able to good utilization, then be a very big progress.
The objective of the invention is one of waste residue that utilizes citric acid production-bacterium slag (comprising black-koji mould, wheat bran, fecula) extracts food dye and makes a pair product feed with it.
The solution of the present invention is: after above-mentioned waste residue is filtered with the E solvent soaking, will make the finished product edible brown pigment after the drying pulverizing after the gained filtrate evaporation concentration.Filtering back gained filter residue is a kind of good pig feed, makes finished product.
Concrete technical process is as follows:
(waste residue and E solvent ratios 1: 1-2) soak 6-12 hour, temperature is that 20-50 ℃ → filtrations → filtrate high temperature evaporation is concentrated, and filter residue is made finished product feedstuff → send into oven for drying → pulverizing → packing with E solvent soaking waste residue.
The E solvent obtains reclaiming rate of recovery 60-90% after the evaporation concentration.
Products obtained therefrom is brown, is water-soluble edible brown pigment, is 37000EBC unit through check pigment rate.Productive rate 3.8%.
Gained is paid the finished product feed and is contained more rich nutrition, and protein content is 27%.
The present invention is solved the unsolved for many years three wastes problem of puzzlement Citric Acid Plant preferably, and the stable performance of major product edible brown pigment except that being applied to foodstuffs industry, also can be used for pharmacy, cosmetic industry.Produce the method for ammonium sulfate and light calcium carbonate with the waste residues calcium sulfate that produces in the citric acid production that utilizes that the present invention finishes simultaneously, the two big waste residues that citric acid industry is produced are fully utilized.
Embodiment 1:
Waste residue 500g, E solvent 500g soaked 12 hours at normal temperatures, got brown pigments 6.9g, E solvent recovering rate 85%.
Embodiment 2:
Waste residue 500g, E solvent 1000g soaked 8 hours, and 30 ℃ of temperature get brown pigments 19g, E solvent recovering rate 76%.
Embodiment 3:
Waste residue 500g, E solvent 500g soaked 8 hours, and 20 ℃ of temperature get brown pigments 9.5g, E solvent recovering rate 85%.
Embodiment 4:
Waste residue 500g, E solvent 500g soaked 8 hours, and 50 ℃ of temperature get brown pigments 13g, E solvent recovering rate 44%.
Claims (2)
1, a kind of method of handling citric acid industrial waste residue-bacterium slag, it is characterized in that aforesaid method is to use the E solvent soaking after filtering with gained filtrate finished product edible brown pigment after high temperature evaporation concentrates oven dry in waste residue, its pigment intensity is 37000EBC unit, to filter the gained filter residue simultaneously and make the finished product pig feed, concrete technical process is as follows:
With E solvent soaking waste residue (waste residue, E solvent ratios 1: 1～2) time 6-12 hour, temperature 20-50 ℃ → filter (filter residue is the finished product feed in addition) → high temperature evaporation concentrated filtrate → send into oven for drying → pulverizing → packing.
2, a kind of method of handling citric acid industrial waste residue-bacterium slag according to claim 1, E solvent and waste residue ratio are 2: 1 when it is characterized in that with E solvent soaking waste residue, soaking temperature is that 30 ℃, time are 8 hours the bests.
