PITTING IN CANNED GREEN BEANS: EFFECT OF CULTURAL PRACTICES, TIN COATING, VACUUM, CORROSION ACCELERATORS AND STORAGE CONDITIONS

摘要

ABSTRACTGreen beans grown under different cultural conditions and packed in #25 and #50/25 R‐enameled cans with variations in vacuum and pH and with added Cu, Fe, NaCl, NO3and NO3with PO, were visually examined for pitting after storage at 38°C and room temperature. The #25 cans and those with high levels of Cu, Fe NO3and with low pH values had the most severe pitting. High can vacuum exhibited a protective effect against pitting during short term storage at room temperature. Pitting severity was not affected by heavy Cu(OH)2sprays during the growing season, but there was an effect between cultiva
