modern method for detection thickeners in dairy product

Determination of some thickeners in dairy products.

A method for rapid determination of thickeners is described, based on the following steps: removal of fat with dioxane; enzymic hydrolysis of starch; precipitation of protein with trichloroacetic acid; precipitation of polysaccharides in 80% ethanol (2 h); hydrolysis in trichloroacetic acid (0.5 mol/l) for 4 h at 100 deg C; conversion of the resultant
