Abstract
<p>Peach and passion fruit nectars are well accepted by consumers and promise important sources of bioactive compounds. In this study it was analyzed vitamin C; anthocyanins; pH; total soluble solids; titratable acidity; total carbohydrates and <em>Ratio </em>(<em>Ratio</em> of total solids to citric acid) in different brands of peach and passion fruit nectar and results were compared to the Brazilian Legislation. Values of Vitamin C, anthocyanins, pH, soluble solids, titratable acidity, and total carbohydrates<em> </em>were analyzed. Results showed many variations in acidity, total soluble solids, carbohydrates and <em>Ratio</em> of nectars of the different brands. Peach and passion fruit nectars marketed in Brazil are good alternatives of ingesting vitamin C as all brands have more than 30% of the recommended daily intake, however, most brands possesses values much higher than stated on the labeling. For anthocyanins values, although there are patterns in Brazilian law, it can be seen from the results that there is great variation between the brands and some have very low values, indicating that the incorporation of this parameter on the labeling would be important once more aware and concerned consumers could choose the brand they thought most appropriate for their need. In conclusion it is possible to say the peach and passion fruit nectars marketed in Brazil are good alternatives of ingesting vitamin C as all brands have more than 30% of the recommended daily intake indicating they are considered “rich in vitamin C”. Although, in the other hand, brands of both flavors are found in amounts higher than stated on the labeling. Values of soluble solids, acidity in citric acid and total carbohydrates are according Brazilian Legislation. Values of<em> Ratio </em>indicate that the nectars analyzed are adequate according to acceptability parameters.</p>
