Y-Milk protein rapid test reagent

Product introduction

Application

It is widely used for rapid detection of protein in milk powder

Detection principle

The protein content of counterfeit milk often does not reach the standard. Long-term consumption of such milk may cause infant malnutrition, growth retardation, and bony edema, head generally small, reduced immunity, organ damage or even life-threatening. Therefore, the determination of protein content in milk is very important for food safety testing. The speed test box proteins using the classical method of measuring the protein in milk powder can be quickly generated with the purple product of the reagent, the deeper the color, that the higher the protein content of the sample, compared with the standard color scale can be drawn the semi-quantitative results of protein samples.

Specification: 50 times.

Storage: normal temperature, avoid from the sunlight.

Packing: the test solution A: 1 bottle.

Period of validity: 6 months.

Usage

1. take the plastic cup to weigh up 1 grams milk powder and use the plastic scale straw to add 14ml distilled water or pure water, stirring with straw or shaking to make the powder dissolved or dispersed evenly, and then put the sample liquid for more than 10 minutes and constant stirring, dissolving the homogeneous suspensions is the sample solution.

2. Use the plastic scale straw to take 2ml test solution A into the control bottle. Use the plastic straw to mix the sample solution again and then draw the milk sample solution and drop 5 drops to the test solution A bottle, shake for mixed. Color for 5 minutes to observe color changes and compare with the standard colorimetric card, find out the color gradation is similar with the color card, that is the protein content of each 100g in milk powder sample. When the sample is below the standard amount of protein content, can be sent to the laboratory for further testing.

Announcement

1. The solubility of some milk products are poor, in order to ensure the sample homogeneity and representative sampling, during reaction to stir the sample liquid again.

2. Reagents placed long-term will appear a little white precipitate, does not affect the determination of. If appear black precipitate should discard.

3. Experimental water should use distilled water or pure water;

4. After each use, laboratory glassware should be washed with water, and then use distilled water or pure water after the dry spare, or there may be a colored reaction product precipitated, affect the use.

5. Reagents are corrosive. Pay attention to the protection.
