Patulin accumulation in apples during postharvest: Effect of controlled atmosphere storage and fungicide treatments

“…It is well known that although decay of fruits proceeds slowly at cold storage, rapid development occurs when the fruit is transferred to a warm environment (Fallik et al, 2001). In our study, when apples were further stored at 20°C during three days, a mean increase of 40% in lesion diameter occurred.…”

“…In general, fungicide treatment was more eVective when applied to ripe apples regardless of the time of storage. The changes in Xesh of fruit which become softer in over-ripe climatic of fruits (Fallik, Tuvia-Alkalai, Copel, & Wiseblurm, 2001) makes resistance of fruit to fungal infection decrease and could favor fungi development. Otherwise, these changes may also increase the permeability of fruit to active principles of fungicides which could enter the Xesh easier and be more eVective.…”

Patulin accumulation in apples by Penicillium expansum during postharvest stages

“…Combinations of imazalil and folpet are commonly used in packinghouses to prevent blue mould and other pathologies in apples but their efficacy may depend on fruit conditions as shown in this study. Ripening of most climacteric fruits is characterized by softening of the flesh, enhanced colour development and increase in respiratory activity (Fallik et al. 2001).…”

Ripening of most climacteric fruits is characterized by softening of the flesh, enhanced colour development and increase in respiratory activity (Fallik et al 2001). These processes make overripened fruits more sensitive to the attack of moulds in Table 1 Analysis of variance of lesion sizes (mm), both at the end of cold storage and after 3 days at 20°C and significance of the assayed factors Source of variation d.f.…”

Influence of post-harvest technologies applied during cold storage of apples in Penicillium expansum growth and patulin accumulation: A review

“…Sydenham et al (1997) reported that limited storage and processing capacities may result in apples being stored in the open for considerable periods, which may increase the possibility of patulin accumulation. Decay is slow at cold storage temperatures, but rapid development occurs when the fruit is transferred to a warmer environment (Fallik, Tuvia-Alaklai, Copel, Wiseblum, & Regev, 2001). Besides, optimum temperature for P. expansum to produce patulin in vitro is 20°C (Pitt & Hocking, 1997).…”
