| Edible films or coatings could be used as an alternative way of conservation, because of their ability to reduce respiration and transpiration rate, maintain firmness and generally delay fruit senescence. The aim of this research was to evaluate the influence of different types of coating: sodium alginate (Al), pectin (Pe) and sodium alginate plus pectin (Al + Pe), on some blueberries quality characteristics, cell viability and microbial growth during 14 days of storage at 4 °C. Blueberry samples differently coated did not show significant differences in weight loss, pH, soluble solid and dry matter content. However, the application of Al, Pe and Al + Pe improved the firmness of blueberry samples as compared to the uncoated one. Changes in the surface... |

| 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... |

| The aim of this work was to evaluate the efficacy of an innovative edible coating, based on chitosan from mushrooms enriched with procyanidins extracted from grape seeds, on fresh blueberry quality maintenance, (weight loss, pH, dry matter, colour, firmness and antioxidant activity) and microbial growth, during 14 days of storage at 4 °C. For weight loss, pH and dry matter no relevant differences were detected among the control and the differently coated samples at each considered storage time. Chitosan and chitosan + procyanidins coatings promoted a slight decrease of luminosity and an increase of blue hue colour of blueberry samples during the whole storage period. The use of coating promoted an increase in the antiradical activity that was the... |
