Abstract
The quality of a product is compromise between many factors, one of which is high level of sensory appeal Of major importance among factors determining marketing success of a new food product is consumers' acceptability. Two kinds of new dessert milk products based on whey proteins were studied. Consumers (60 persons) tasted samples using nine-point hedonic scale. Quality was evaluated as well using sensory scoring method and 20-point scale. Fresh samples and cold stored samples (4 °C, 85% R. H.) were evaluated every 7 days (during 35 days) at room temperature (20 °C) by a panel composed of 5 members. Data of sensory and hedonic evaluation of quality were statistically analyzed. The results of hedonic scale application showed high consumers acceptability (above 95%) of new products. Sensory scoring pointed out significant changes in quality of both soft albumin cheeses during storage, that was not fast and strong enough to reach cut-off level (<11,2 points) during 35 days of storage. Concluding it is possible to state that quality level of new products was very high as according to consumers 'or sensory analitcs' opinion.
