Question

Identify the false statement about gelatin used in the preparation of capsules.

• A. \( \text{Type A gelatin has an isoelectric point in pH region of 9} \)
• B. \( \text{Type B gelatin has an isoelectric point in pH region of 4.5} \)
• C. \( \text{Type A gelatin is derived from an alkali treated precursor} \)
• D. \( \text{Type B gelatin is derived from an alkali treated precursor} \)

Hint:

Remember: Acid treatment for Type A, Alkali treatment for Type B. The isoelectric points also differ significantly between the two types.

Answer 1

The Correct Option is C

Gelatin is derived from collagen and is primarily of two types: Type A and Type B. - Type A gelatin is derived from acid-treated collagen precursors and has an isoelectric point typically between pH 7 and 9. - Type B gelatin is derived from alkali-treated collagen precursors and has an isoelectric point typically between pH 4.5 and 5.2. Therefore, the false statement is that Type A gelatin is derived from an alkali-treated precursor. It is actually derived from an acid-treated precursor.
