Question

Metallic flavor defect in lassi is caused due to:

• A. Contamination of milk with zinc or chromium during heating
• B. Contamination of milk with nickel or copper during heating
• C. Contamination of milk with iron or magnesium during heating
• D. Contamination of milk with iron or copper during heating

Hint:

Use stainless steel or food-grade equipment to prevent metallic contamination in dairy products.

Answer 1

The Correct Option is D

A metallic flavor in lassi arises from the leaching of metals like iron or copper into milk during heating. These metals catalyze oxidation reactions, which produce off-flavors. Avoiding the use of metallic containers or ensuring proper maintenance of equipment can prevent this defect.
