Spectrophotometric analysis
According to the Biuret test for protein is additionally useful to total protein’s quantitative determination, Then we are using spectrophotometric analysis.
The casein and pure protein content of skim milk, furthermore as whole milk’s protein content, can be measured with the assistance of Biuret test solutions which contains caustic potash and also a detergent.
The result for the Sudan red assay, a tiny low drop of every test that's substance onto paper.
They're allowed the drops to dry (a hairdryer helps), soak the paper during a dish containing 0.2% Sudan IV for five min, rinse and also dry the paper, and so also use the presence of a red spot to verify the presence of lipid.
Thus, milk would test positive within the Biuret test and negative within the Sudan red test. simply because milk has protein.
The correction option is A. Skim milk.
