Product introduction

Detection Principle

Commonly known as saccharin sodium saccharin, sucrose, its sweetness is about 450-550 times, so the one hundred thousandth of an aqueous solution will be taste sweet.

saccharin Of food react with this reagent to produce a blue reaction product, the deeper the color, that higher levels of saccharin sodium in the sample, compared with the standard color cards, samples of saccharin can be drawn semi-quantitative information.

Application

Applicable to a wide range of samples used to detect various types of foods such as pickles, preserves, beverages, starch products, test the saccharin sodium content of these products.

Reagent components

Test liquid A: 25ml / bottle

Chloroform for self-service

Experimental Methods

1. Liquid samples: Take 5 ml in volume directly test tube with stopper, adding test solution A 0.5ml (10 drops), shake and let stand 2 minutes, add 2ml chloroform, strong vigorously for 1 min (about 200), standing stratification. Observe the lower color.

2. Solid samples: Weigh 0.5g cut sample, put a plug in a test tube, add water for 5ml, shaking and extract, then adding test solution A 0.5ml (10 drops), shaking out for 1 minute, stand for one minute, then adding 2ml chloroform, strong shaking for 1 minute (about 200 times), standing for layering. Observe the lower color.

Results judgment

Observed the lower color after layering, and compared with the color card. Similar color from the color card is marking the saccharin sodium content of samples. If it is the solid samples, the saccharin sodium content should be the color card similar value multiplied by ten.

Announcement

The reagents should be closed after use and stored in the refrigerator or a cool dry place.All experiments should use distilled water.
