Description
Technical field
The present invention relates to food additives production technical field, more particularly to a kind of citric acid Quality identification method.
Background technology
Citric acid is the essential composition in food additives compounding leavening agent, because food additives are related to diet
Security problems, its composition and quality requirement are all very high, therefore are needed before citric acid is added into compounding leavening agent to lemon
The quality of lemon acid is differentiated that existing process program and flow, process are complicated, and the order of accuarcy of discriminating is low, once by
Cause compounding leavening agent product quality unqualified in the quality problems of citric acid, huge economic loss will be produced, tradition
Method identification efficiency is low, wherein using to some chemical reagent the injury of body may be caused to workman.
The content of the invention
The purpose of the present invention is exactly that conventional method identification efficiency is low, order of accuarcy is low, to the body wound of workman in order to overcome
The big defect of evil, devises a kind of citric acid Quality identification method, and process is simple, and identification efficiency is high, small to worker injuries.
The required technical problem solved of the invention can be achieved through the following technical solutions：
A kind of citric acid Quality identification method, comprises the following steps：
S1, observation lemon acid starting material shape；
S2, clean reagent bottle, liquid flowing tube etc.；
S3, take citric acid test solution 30ml inject reagent bottle, add hydrochloric acid；
S4, above-mentioned test solution 50ml is taken, add copper-bath；
S5, with hydrochloric acid platinum filament is moistened, calcination is to colourless on colourless flame；
S6, the test solution for dipping S3 a little, burn in the colourless flame of step 5；
Step 1 raw material is white or slightly yellow fibrous powder.
White precipitate is produced in step 3 test solution.
The light blue precipitation of villiform is produced in the step 4 in test solution.
The flame of the step 6 is in foresythia.
As a result of above technical scheme, the invention has the advantages that：
Citric acid Quality identification method disclosed in this invention, directly using reagent is added in reagent bottle, observes raw material character
Change judge that whether up-to-standard citric acid is, process is simple, and product quality meets the requirements, and the discrimination method differentiates
Efficiency high, circumstance and good operation conditions are small to worker injuries.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, enter below
One step illustrates the present invention.
A kind of citric acid Quality identification method, comprises the following steps：
S1, observation lemon acid starting material shape；
S2, clean reagent bottle, liquid flowing tube etc.；
S3, take citric acid test solution 30ml inject reagent bottle, add hydrochloric acid；
S4, above-mentioned test solution 50ml is taken, add copper-bath；
S5, with hydrochloric acid platinum filament is moistened, calcination is to colourless on colourless flame；
S6, the test solution for dipping S3 a little, burn in the colourless flame of step 5；
Step 1 raw material is white or slightly yellow fibrous powder.
White precipitate is produced in step 3 test solution.
The light blue precipitation of villiform is produced in step 4 in test solution.
The flame of step 6 is in foresythia.
Citric acid Quality identification method disclosed in this invention, directly using reagent is added in reagent bottle, observes raw material
The change of character judges that whether up-to-standard citric acid is, and process is simple, and product quality meets the requirements, the discrimination method
Identification efficiency is high, circumstance and good operation conditions, small to worker injuries.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent is defined.
