Question

Identify the correct statements about concentrated juice:
A. Vacuum evaporation reduces thermal damage of fruit juice concentration
B. Aroma compounds may be lost during juice concentration
C. Fruit juice concentration increases microbial load
D. Reconstitution of concentrated juice restores original juice quality completely
E. Concentrated juices have lower storage volume
Choose the correct answer from the options given below:

• A. A, B, C, D only
• B. A, B, C only
• C. A, B, D only
• D. A, B, E only

Hint:

Concentration saves volume but may lose aroma.

Answer 1

The Correct Option is D

Concept: Juice concentration is used to reduce water content for easier storage and transport, typically using vacuum evaporation to minimize thermal degradation.

Step 1: Evaluating Statement A.
Vacuum evaporation:
• Lowers boiling point of water
• Reduces exposure to high temperatures
• Minimizes thermal damage Hence, correct.

Step 2: Evaluating Statement B.
During concentration:
• Volatile aroma compounds may evaporate Thus, correct.

Step 3: Evaluating Statement C.
Concentration:
• Removes water
• Reduces water activity
• Does not increase microbial load Hence, incorrect.

Step 4: Evaluating Statement D.
Reconstitution:
• Cannot fully restore original quality
• Losses in aroma and nutrients occur Thus, incorrect.

Step 5: Evaluating Statement E.
Concentrated juices:
• Occupy less volume
• Easier to transport and store Correct.

Step 6: Final selection. \[ A, B, E \] Final Conclusion:
Option (4) is correct.
