Step 1: Understanding the Concept:
This question tests knowledge of fruit processing, specifically the requirements for jelly making.
Step 2: Detailed Explanation:
Jelly is a clear, semi-solid product made from fruit juice, sugar, and pectin.
For successful jelly making, a fruit must have:
A. Rich in pectin: Pectin is essential for gel formation. Guava is naturally high in pectin.
B. Good flavor: Guava has a distinct, pleasant flavor that enhances the jelly.
C. Rich in Vitamin C: While guava is rich in Vitamin C, this is not a requirement for jelly making.
D. Good acidity: Acidity (pH 2.8-3.5) is crucial for pectin gelation. Guava has good natural acidity.
E. Good TSS: TSS (Total Soluble Solids) is important for sweetness but not a primary requirement for jelly.
Thus, the essential properties are pectin content (A), flavor (B), and acidity (D).
Step 3: Final Answer:
Thus, the correct options are A, B and D only, which corresponds to option (C).
