The effects of various stearic-palmitic acid blend concentrations in f
ilms, storage temperatures and storage times on potato chip quality we
re evaluated using Response Surface Methodology. Storage temperature a
nd time affected the quality of potato chips. The maximum storage time
s for acceptable potato chip quality were. 30 to 43 days, 23 to 25 day
s, and 11 to 12 days for storage temperatures of 15, 25 and 35 degrees
C, respectively. Results were independent of stearic-palmitic acid bl
end concentrations.
