Fats and oils - 344 Iodine value of an edible oil INTRODUCTION Fats and oils known as triglycerides contain long chain hydrocarbons with carboxyl groups (COOH groups). These fatty acids are classified into the number of double bonds present in the fatty acid. When the carbon atoms in these chains are bounded to the maximum possible number of hydrogen atoms‚ the triglyceride is said to be saturated. When one or more double bonds exist between carbon atoms in the chain‚ less hydrogen exists
