Q.Assertion (A) : Vegetables rich in tannin turn brown on cutting. Reason (R) : This is due to maillard reaction. Code :
Correct answer: (A) is true and (R) is false.
Explanation
Vegetable rich in tannin turn brown on cutting this is due to the enzyme called polyphenol oxidase. In the presence of oxygen the PPO enzymes changes substances known as phenolic compound through the process of oxidation into different compounds called quinones. The quinones then react with other compound and turns the colour of vegetable to brown.
