Question:
Which of the following constituents of ice cream mix renders 'chew resistance' to ice cream?
Which of the following constituents of ice cream mix renders 'chew resistance' to ice cream?
Show Hint
Milk proteins (found in MSNF) bind water and increase mix viscosity, which directly builds the structural matrix responsible for the desirable "chewy" body of ice cream.
Updated On: Jul 21, 2026
- Milk fat
- Vegetable fats
- Milk solids not fat
- Alternative polyol sweeteners

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Chew resistance (or "chewiness") refers to the resistance of ice cream to melting and deformation when chewed.
It is an important textural attribute associated with the body and structure of the ice cream.
The structural framework of ice cream is formed by a combination of air cells, ice crystals, fat globules, and a concentrated unfrozen serum phase.
Step 2: Detailed Explanation:
Let us analyze the role of the different mix constituents:
- Milk fat and vegetable fats contribute to the richness, smooth texture, and melt-down characteristics of the ice cream, but they do not primarily determine chew resistance.
- Alternative polyol sweeteners lower the freezing point and keep the product soft, but they can reduce chewiness if used in excess.
- Milk Solids-Not-Fat (MSNF) consists of proteins (casein and whey), lactose, and minerals.
The proteins in MSNF are highly hydrophilic and have excellent water-binding capacity.
These proteins increase the viscosity of the unfrozen serum phase, assist in air cell stabilization, and form a structural matrix that resists mechanical deformation.
This protein-rich matrix directly provides body and "chew resistance" to the finished ice cream.
Therefore, MSNF is the constituent primarily responsible for rendering chew resistance.
Step 3: Final Answer:
The constituent that renders chew resistance to ice cream is Milk solids not fat (MSNF).
