Question 4
Marks : +2 | -2
Pass Ratio : 100%
_____ help in maintaining/controlling the acidic/alkaline changes during food processing and hence maintain flavor and stability.
Buffering agents
Sequestrants
Anti-caking agents
Anti-foaming agents
Explanation:
Buffering agents help in maintaining/controlling the acidic/alkaline changes during food processing and hence maintain flavor and stability.
Question 5

Pass Ratio : 100%
What are Sequestrants?
They are added to keep the food stable
Form a complex ion with metals like copper, iron etc
Added for color
They keep the food oxidized
Explanation:
Sequestrants form a complex ion with metals like iron etc. These metals trigger auto-oxidation. Hence, forming complexes prevents them from reacting with oxygen and leading to rancidity etc.
