Title: To determine acid value of Lipid
Description: The notes titled "To determine acid value of Lipid" describe a laboratory procedure to measure the acid value of a lipid sample. The acid value is a measure of the free fatty acids present in the lipid and is expressed as the amount of potassium hydroxide (KOH) required to neutralize the free acids in one gram of the sample. The procedure involves weighing a sample of the lipid and dissolving it in a solvent such as chloroform. A known amount of KOH solution is then added to the sample, which is heated and stirred until the free fatty acids are neutralized. The excess KOH is then back-titrated with a standard solution of hydrochloric acid (HCl) using a pH indicator such as phenolphthalein. The acid value is calculated as the amount of KOH used to neutralize the free fatty acids in the sample, divided by the weight of the sample in grams. The result is expressed as the number of milligrams of KOH required to neutralize one gram of the sample, which is a measure of the degree of hydrolysis or deterioration of the lipid. The acid value of a lipid is an important parameter for quality control and can be used to monitor the freshness and stability of fats and oils in food products, cosmetics, and pharmaceuticals. High acid values can indicate rancidity or spoilage, which can affect the taste, odor, and nutritional value of the product.
