Sensorial evaluation and physical-chemical stability of a blend of orange and carrot. Ciênc. Tecnol. Aliment. [online]. 2007, vol.27, n.1, pp. 7-12.

In this work a "blend" of orange and carrot juice with different proportions of carrot (5 and 25%) and concentrated to different degrees of soluble solids (15 and 30 °Brix) was developed. Physical and chemical analyses of the raw material and most sensorial preference "blend" were carried out with the main aim of characterizing the product. Special attention was paid to observe changes in the proportion of ascorbic acid and total carotenoides after the concentration juice process. The physical and chemical stability of the blend was also investigated during a period of sixty days. In the sensorial analysis the ordering preference test was applied. The results showed that the formulation with the most sensorial preference was that with 5% of carrot and concentration up to 15 °Brix. The concentration process and the storage, for the period of 60 days, caused a significant reduction of the contents of ascorbic acid and total carotene.
