You're on a roll — Here are the inferences about the food substances: J: The formation of a brick-red precipitate* with Fehling's solution upon heating indicates that food substance J is a reducing sugar. K: The blue-black colour* obtained when iodine solution is added to food substance K indicates that K contains starch. L: The initial test with Benedict's solution showing no change in colour* indicates that L is not a reducing sugar. However, after hydrolysis with dilute hydrochloric acid and subsequent boiling, a yellow precipitate* is obtained. This positive result for reducing sugars after hydrolysis indicates that L is a non-reducing sugar (e.g., sucrose), which was broken down into reducing sugars. Got more? Send 'em!
