Heat treatment effects on ripening and disease infection of Philippine bananas and mangoes.

Hot water dip (HWD) of 47-52 deg C for 10-20 minutes inhibited ripening, anthracnose (Colletotrichum musae) and finger rot (Botryodiplodia theobromae and Fusarium spp.) in Musa AAB cv. 'Latundan' and Musa BBB cv. 'Saba' bananas held at ambient temperature (26-32 deg C, 68-90% RH). When fruits were enclosed in plastic bag during dipping (indirect HWD), 47-49 deg C was as effective as 50-52 deg C direct HWD. In 'Indian' and 'Carabao' mangoes, HWD did not affect ripening but reduced anthracnose (C. gloeosporioides), stem-end rot (Diplodia natalensis) [Botryodiplodia theobromae] and soft rot infections. Preheating 'Carabao' mangoes in 40 deg C water for 10-20 min prior to 54-56 deg C HWD gave better disease control than the previously established HWD (51-54 deg C, 10 min). HWD had no adverse effect on fruit quality.
