| Ultrasounds are air vibrations and they generate a rapid series of compression and expansion, having an increasing effect on mass diffusion when combined with osmotic dehydration process (OD). The aim of this work was to investigate the effect of ultrasound (US) pretreatment on the texture, color, chlorophyll content, water activity and thermal properties in terms of freezable water content of osmotic dehydrated kiwifruit. Kiwifruits slices (10 mm thick) were subjected to ultrasonic waves in the bath at a frequency of 35 kHz for 10, 20 and 30 minutes. The osmotic dehydration was carried out by immersion of the samples in 61.5% sucrose solution equilibrated at 25°C for pre-established contact period of 0, 10, 20 and 30 min. The results showed that... |

| Cranberries are appreciated for their high amount of antioxidants such as flavonoids, anthocyanins,phenolic acids, carotenoids and vitamins. However, due to their sour and tart taste they request to beprocessed into sweeter dried fruits in order to be acceptable for the consumers. The aim of this work wasto analyse the effect of ultrasound assisted osmotic dehydration on mass transfer parameters and onquality characteristics during storage of cranberries. Ultrasound treatment was performed at the fre-quency of 21 kHz for 30 min in three osmotic solutions - 61.5% sucrose, 30% sucrose with an addition of0.1% of steviol glycosides and 40% trehalose on cut in half cranberries. Afterwards, the cranberry sampleswere subjected to osmotic dehydration process at... |
