Question:
During the manufacture of whipping cream which of the following processes improves whipping property?
During the manufacture of whipping cream which of the following processes improves whipping property?
Show Hint
Ageing whipping cream at 4--5$^{\circ}$C for 12--24 hours allows the milk fat to crystallize, which is necessary for the partial coalescence that supports and stabilizes the whipped foam structure.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Whipping cream requires the formation of a stable foam.
This foam is stabilized by a network of partially coalesced fat globules that align at the air-water interface to trap air cells.
Step 2: Detailed Explanation:
To achieve good whipping properties (including rapid whip time, high overrun, and low synersis), the cream must undergo an ageing step:
1. Fat Crystallization: Ageing involves storing the pasteurized cream at low temperatures (typically 4--5$^{\circ}$C) for a minimum of 12 to 24 hours.
This cold storage allows the milk fat within the globules to crystallize.
A specific ratio of solid-to-liquid fat is required to facilitate partial coalescence during whipping.
If the fat is not sufficiently crystallized (due to lack of ageing), the liquid fat will cause complete coalescence, leading to buttering rather than foam formation.
2. Protein Hydration: Ageing allows milk proteins and emulsifiers to adsorption-equilibrate at the fat globule surface, which helps stabilize the fat globule membrane.
While homogenization can reduce globule size, excessive homogenization can impair whipping properties by creating a highly stable membrane that resists the partial coalescence needed to support foam structure.
Fermentation and acidification produce sour cream or cultured cream, which increases viscosity but is not used to manufacture standard sweet whipping cream.
Step 3: Final Answer:
Therefore, the ageing process is used to improve the whipping properties of cream.
