| This work was aimed at studying the influence of PFJ and/or sodium disulphite on Yacon pulp colour, and evaluating the sensory attributes of Yacon non-sugar pastes. A colour kinetic evaluation of browning in 11 treatments containing Yacon tubers, yellow passion fruit juice (PFJ) and/or sodium disulphite, over the course of 240 minutes was studied to inactivate the PPOs activity. The evaluation of the colour alterations of Yacon tuber by the addition of variable amounts of PFJ and sodium disulphite enabled identification of efficient treatments for the inhibition of browning: T7 (300 g kg -1 PFJ), T8 (400 g kg -1 PFJ), and T10 (150 g kg -1 PFJ + 0.25 g kg -1 sodium disulphite). These treatments presented high colour intensity (C*) and an insignificant (P... |

| Jaboticaba is a Brazilian fruit, native to the Atlantic forest, which belongs to the Myrtaceae family. In this work we describe the effect of the thinning of "flower", "fruit" and "flower & fruit" compared to non-thinned fruit (control) and of edible coatings with respect on nutritional composition, overall acceptability and shelf-life of jaboticaba ‘Sabara’, grown in an irrigated commercial orchard. "Flower and fruit" thinning allows fruit with higher quality as diameter, volume and mass. Non-thinned fruit shows higher yield, however fruit have lower quality. As a result of the improving quality at harvest, the shelf life was twice (~8 days) for thinned fruit. The lack of change in concentration of soluble sugar and absence of formation of... |
