Embodiment Construction

[0018] The present invention will be further described below in combination with specific embodiments.

[0019] The detection method of sodium saccharin content in the feed sweetener of the present invention, detection steps are as follows:

[0020] 1) Dissolve the sweetener sample with saturated saccharin salt solution. The saturated saccharin salt solution required per gram of sweetener sample is 10-20ml; the saturated saccharin salt solution means that both saccharin and salt are saturated in the aqueous solution to form a mixed solution;

[0021] 2) Add excess hydrochloric acid to the solution obtained in step 1), and adjust the pH<1, so that sodium saccharin can generate saccharin under the strong acid condition of pH<1, stir and let it stand until pure saccharin is completely precipitated at the bottom of the container;

[0022] In actual operation, add 2.0ml of hydrochloric acid per gram of sweetener sample to drop hydrochloric acid into the solution obtained in step 1)...

Abstract

The invention discloses a method for detecting the content of saccharin sodium in feed sweetening agent. The method comprises the following steps that 1, sweetening agent samples are dissolved by saturated saccharin salt solution; 2, excessive hydrochloric acid is added so that the saccharin sodium generates saccharin under the strong acid conditions; 3, after a small amount of hydrofluoric acid is dripped, filter paper is used for filtering, and purified saccharin is obtained; 4, washing is carried out; 5, the purified saccharin is put into a beaker containing hot alcohol for dissolving, phenolphthalein is added, then, alkali is used for dripping until solution generates reddish color, in addition, the color cannot be faded within 30s, and the consumed alkali quantity is recorded; and 6, the content of the saccharin sodium in the feed sweetening agent can be obtained through calculation. The method has the advantages that the influence caused by drying agent and carriers is reduced, the detection of the content of the saccharin sodium in the feed sweetening agent is more precise, and the consumed detection time is about 30 minutes and is greatly shortened.

Description

technical field [0001] The invention relates to the improvement of the technology for detecting the sodium saccharin content, specifically a method for detecting the sodium saccharin content in feed sweeteners, and belongs to the technical field of sodium saccharin content detection. Background technique [0002] In the prior art, there are mainly two methods for detecting the content of saccharin sodium: 1. perchloric acid titration; 2. high performance liquid chromatography. The perchloric acid titration method is a method in the national standard for the detection of pure sodium saccharin. The advantages of the perchloric acid titration method are: short time-consuming and high accuracy for pure product detection. Disadvantages are: strong specificity, can only be used for pure product testing, and the test results of sodium saccharin added with excipients are unstable and easily affected by excipients. Since the feed sweetener contains a certain amount of carrier and de...
