ALTERNATIVE COMPOUNDS FOR the MAINTENANCE of PROCESSING QUALITY of STORED POTATOES (SOLANUM TUBEROSUM)

Abstract

alternative sprout inhibitors were testedfortheir efficacy in retaining processing quality of potatoes during long term storage. Carvone, dimethylnaph-thalene and ethylenewere compared to the commercial standard, CIPC, (isopropyl N-(3-chlorophenyl) carbamate) and anair control, for their effects on sprout development, fry color andsugar content of potato tubers, during 25 weeks ofstorage at 9C. All treatments reducedsprouting although the amount of sprouting variedamong treatments. At the end of the 25 week storage period, the amount of sprouting based on total sprout weightand maximum sprout length was, inorder from least to most, CIPC, carvone, ethylene, DMN and air, Poorer processing quality due to darker fry dcolor and higher levels of reducing
