The material mainly used for manufacturing dairy utensils is:
- Aluminum / Stainless steel ✓ Correct
- Copper
- Iron
- Bronze
Explanation:
Correct Answer: Aluminum / Stainless steel
Aluminum and stainless steel are the materials mainly used for manufacturing dairy utensils. Stainless steel (SS 304 or SS 316) is the preferred material in modern dairies.
Why Stainless Steel and Aluminium?
- Non-reactive with milk acids and cleaning agents.
- Easy to clean and sanitize (smooth, non-porous surface).
- Durable and resistant to corrosion.
- Does not impart off-flavours or metallic taste to milk.
- Meets food-grade safety standards.
Why Other Metals Are Avoided
- Copper: Catalyzes oxidative rancidity in milk fat; causes off-flavours.
- Iron: Rusts easily; iron contamination (though karahi/iron pans are used for khoa making, giving high iron content of 103 ppm).
- Bronze: Contains copper — same issues as copper.
