Step 1: Understanding the Concept:
The question asks to identify the product from the list that does not use casein or its derivatives (caseinates) as an ingredient. Casein is the main protein in milk, known for its functional properties like emulsification, water binding, and nutritional value.
Step 2: Detailed Explanation:
(A) Ice cream: Sodium caseinate is sometimes used as a stabilizer and emulsifier in ice cream to improve its body and texture.
(B) Coffee whiteners: Sodium caseinate is a key ingredient in most non-dairy coffee whiteners. It encapsulates the fat droplets, providing excellent whitening power and preventing oil separation.
(C) Imitation milk: In imitation or filled milk, where milk fat is replaced by vegetable fat, caseinates are often used as the protein source and to emulsify the fat.
(D) Whevit: The name "Whevit" is derived from "Whey". It is a brand name for a whey-based beverage. The protein source in such a product is whey protein, not casein. Adding casein would be contrary to the product's concept.
Step 3: Final Answer:
Whevit is a whey-based product and therefore does not use edible casein as an ingredient.
