This study investigated the effects of 1-methylcyclopropene and sanitizer (acidified sodium chlorite or sodium hypochlorite), treated alone or in combination. on microbial growth and quality of packaged fresh-cut cilantro (Coriandrum sativum L.). Cilantro bunches were treated with 1.5 mg L-1 1-methylcyclopropene or air for 18 h at 10 degrees C. The samples were then cut and washed in tap water, 100 mg L-1 sodium hypochlorite, or 100 mg L-1 acidified sodium chlorite solution for 1 min. The washed cilantro leaves were centrifugally dried, packaged with 29.2 pmol s(-1) m(-2) Pa-1 oxygen transmission rate film, and stored at 5 degrees C for 14 d. Results indicated that 1-methylcyclopropene significantly (P < 0.0001) delayed the decrease in 0, and accumulation of CO, partial pressures in the headspace of sample packages. Acidified sodium chlorite application significantly reduced initial coliform/Escherichia coli counts (P < 0.001), and reduced decay rate at the end of storage (P < 0.05). A combination treatment of 1-methylcyclopropene and acidified sodium chlorite, followed by acidified sodium chlorite treatment alone, maintained the lowest decay rates and the highest overall quality scores at the end of storage.
