Development of a low calorie yacon jam: physico chemical, microbiological and sensory characterization

This study aimed to evaluate the physical-chemical, microbiological and sensory characteristics of four formulations of yacon jams. The following characteristics were analyzed: chemical composition, soluble solids, pH, microbiological presence of total coliforms and salmonella at 45 °C, and presence of fungi and yeasts. The yacon jams exhibited high moisture content (> 62%) as well as high concentrations of carbohydrates (> 28%) and total dietary fiber (2.5%), mainly fructooligosaccharides (> 0.9%). The average energy value was 124.6 kcal/100 g. The average pH was 3.8 and the soluble solids measured 27.6 °Brix. All yacon jams complied with standard microbiological requirements and received high acceptance scores, especially the yacon jam and yacon jam with cinnamon. Yacon jam products may offer an excellent alternative to more common jams due to their lower concentrations of simple sugar, lower calorie value, increased presence of dietary fibers, and desirable sensory characteristics.

Desenvolvimento e avaliação sensorial de sobremesa láctea potencialmente simbiótica

This paper aimed to develop a symbiotic potentially milk dessert containing the probiotic Lactobacillus acidophilus and yacon syrup as prebiotic food and assess its sensory acceptability. For the production of the brus initially prepared a yogurt with whole milk added to 10 % sugar, 3% of

ANÁLISE DE RISCO NA AVALIAÇÃO DA INFLUÊNCIA DA MARCA NA ACEITABILIDADE NÃO SENSORIAL DE REQUEIJÃO CREMOSO

Consumer behavior is influenced by intrinsic (sensory characteristics) and extrinsic (non-sensory characteristics) of the product. Among the non-sensory factors, highlights been studied by various areas of knowledge and strength channeled through companies in order to entice the consumer at the time of purchase. In recent decades, many statistical methods have been employed in order to study this important influence on consumer behavior, both in marketing as in sensory analysis. This study aimed to evaluate the impact of brand on the acceptance of cheese using the statistical technique of relative risk. Thus, the sensory test was conducted in two sessions, with the first, the samples were presented coded (test without information) and the second presented with their respective brands. Comparing the results obtained for the two sessions, it was found that there was no change in acceptance of the cheesecurd for all brands and technical statistical analysis showed the relative risk of easy application, interpretation and effective in studies of non-sensory characteristics of food.
