Section 7: Dairy and Food Engineering

Food Freezing, Plank's Equation & Freezing Time

Subtopic: Freezing curves and ice crystal morphology

Question Statement:

Rapid cryogenic freezing of biological tissues compared to slow blast freezing results in:

Options:

  • (A) Numerous small intracellular ice crystals causing minimal cellular membrane rupture
  • (B) Large extracellular ice crystals that puncture cell walls
  • (C) Higher drip loss upon thawing
  • (D) Complete denaturation of all vitamins

Answer Key:

A

Step-by-Step Solution & Explanation

High freezing rates promote rapid supercooling and high nucleation rates, forming many microscopic intracellular ice crystals and preserving tissue texture upon thawing.
