Given below are two statements Statement (I): Fruit bar should... | Agrigyan

• Assertion (A) is True: Freezer burn (surface desiccation, spongy dry texture, and irreversible lipid oxidation) is especially problematic in frozen food items possessing a high surface area-to-volume ratio (cut fruits, vegetables, IQF berries).
• Reason (R) is True and Explains (A): In cold storage rooms with inadequate relative humidity or fluctuating temperatures, the saturation vapor pressure of ice on the product surface exceeds the ambient vapor pressure of the storage room. Moisture directly sublimates from surface ice crystals into the surrounding atmosphere, leaving behind desiccated, open cavities that accelerate oxidation.
• Conclusion: Both (A) and (R) are true, and (R) is the correct explanation of (A) (Option 1).

Correct option: (1) Both (A) and (R) are true and (R) is the correct explanation of (A)

• Statement (I) is True: Thymol and carvacrol are isomeric monoterpene phenols that constitute $60 - 75\%$ of the total essential oil of garden thyme (Thymus vulgaris), responsible for its strong warm antiseptic aroma and antimicrobial potency.
• Statement (II) is True: To minimize transpirational stripping and thermal volatilization of these volatile monoterpenes and preserve green coloration, harvested thyme foliage should be dried at temperatures below $40^{\circ}\text{C}$ in dehumidified air or low-temperature solar dryers.
• Conclusion: Both Statement (I) and Statement (II) are true (Option 1).

Correct option: (1) Both Statement (I) and Statement (II) are true.

• Starch-to-Sugar Breakdown in Cavendish Banana Ripening:
• Green (Stage 1 / Unripe) $\rightarrow$ (IV) $20\%$ Starch: Fully mature green banana pulp is rich in resistant starch ($20 - 25\%$) with minimal free sugars ($1 - 2\%$).
• More yellow than green (Stage 4) $\rightarrow$ (I) $13\%$ Starch: Amylase and starch phosphorylase enzymes progressively convert starch into glucose, fructose, and sucrose; starch drops to approximately $13\%$.
• Yellow with green tip (Stage 5) $\rightarrow$ (III) $7\%$ Starch: Commercial retail stage; starch drops to around $7\%$ while soluble sugars exceed $14\%$.
• Yellow with increasing brown areas (Stage 7 / Overripe) $\rightarrow$ (II) $1.0\%$ Starch: Advanced senescent stage; starch is virtually depleted to around $1.0\%$ with total sugars peaking at $19 - 21\%$.
• Correct Combination: (A)-(III), (B)-(IV), (C)-(I), (D)-(II), matching Option 3.

Correct option: (3) (A) - (III), (B) - (V), (C)- (), (B) - (I)
