y1 = -109.7ln(x)+336.56

y2 = -126.9ln(x)+395.81

where

y1 = storage time in days for sprouting

y2 = storage time in days for spoilage

x = storage temperature in oC

a. How many days are potatoes expected to spoil if stored at 18oC?

b. A farmer discovered his stored potatoes showing a sign of wrinkles and dark spot after 15 days. Determine at what temperatures they must has been stored to cause the spoilage.

c. A food processing company wants to maintain continuous availability of potatoes in the market and wishes to store potatoes for 90 days. What temperature will be required for safe storage?

d. Mr Jackson is planning to prepare some potato tubers for seed for the coming season. How long (days) does he need to store his potato at 19oC to get them to start sprouting?

e. Based on equations 1 and 2, determine whether spoilage symptoms or sporting occurs first for a potato crop stored at 19oC. Briefly explain your answer.
