BIURET FOOD TEST FOR PROTEINS molecules consisting of one or more chains of amino acids.Proteins are complex molecules that react differently to many compounds but are also fragile and cannot withstand high temperatures or strong acids and bases without degrading. The Biuret Method‚ or biuret test‚ is used to detect the presence of peptide bonds. It has this name because it reacts positively to the biuret molecule’s peptide bonds. Correctly evaluating the number of peptide bonds is a step towards

what causes starch to thicken or thin which is relevant to obtaining the desired viscosity for recipes that involve starch cookery without complication. Factors to be considered in the thickening power of cornstarch include the concentration of starch‚ extent of gelatinization thus temperature and duration of heat‚ and the addition of sugar or salt (1). Background Gelatinization‚ a physical change‚ occurs when starch is heated in water. Due to the solubility of the amylose in the starch granule
