Effect of freezing and osmatic dehydration on strawberry of the chandler variety
Keywords:
freezing, osmotic dehydration, strawberriesAbstract
The effects of freezing and osmotic dehydration on the physical-chemical and sensorial characteristicas of strawberries of Chandler variety were investigated. Four physical-sensorial atributes were performed, using the describable quantitative analysis (DQA) with structured scale of 9 points. Four treatmentes were applied to the strawberries: freezing in a household refrigerator without osmotic dehyudration (CST), freezing in a household refrigerator with osmotic dehydration (CCT), freezing in a freezer without osmotic dehydration (FST) and with osmotic dehydration (FCT) pre-treatment, using a 65° Briz solution. The reezing of the strawberries with osmotic dehydration treatment (FCT) obtained the best means in the physical-chemical analysis and in the four sensorial attributes valued (color, appearance, texture and flavor).
