Hysteresis in a hydrocolloid gel is______________?
Correct answer: B. Temperature lag between gelation and liquefaction temperature
- A. Moisture absorption
- B. Temperature lag between gelation and liquefaction temperature
- C. Phenomenon of conversion of gel into sol
- D. All of the above
Explanation
Hysteresis is the temperature difference between liquefaction and gelation of a hydrocolloid, allowing the sol-to-gel and gel-to-sol changes to occur at different temperatures. It is not simply moisture absorption or conversion of gel into sol.
