Abstract

In Brazil new varieties of citrus were selected along the years, but none sensory analysis is usually made to verify the acceptance as one of the bottleneck for fresh citrus juice industry and before the commercial release. We have evaluated the response of consumers (n=62) for eight new hybrids of the crossing between sweet orange and mandarin in five sensory attributes and used analysis of variance Tukey's procedure (HSD) and internal preference mapping for the data processing. The results were compared in relation to their standard physical-chemical characteristics and with commercial varieties: Murcott tangor (Citrus sinensis (L.) Osbeck x Citrus reticulata Blanco), Pera sweet orange (Citrus sinensis (L.) Osbeck, Cravo mandarin (Citrus reticulata Blanco). Hybrids TM x LP 222 and TC x LP 5 are candidates to become variety and TM x LP 94 was chosen for new sensory analysis. Flavor featured as the most important parameter for orange juice and some hybrids with adequate physical-chemical parameters presented low acceptance, while others with inadequate parameters showed good acceptability, what suggests a new way to fruit selection.

As Pera sweet orange as both Murcott tangor and Cravo mandarin can be susceptible in different degrees to several diseases the actual researches in Brazil are focused on phytosanitary aspects and mainly on the pathosystems Citrus variegated chlorosis or CVC, Citrus leprosis virus, Huanglonnbing, Citrus sudden death, Citrus tristesa virus, Phytophthora Gummosis, Citrus canker, Citrus black spot and Alternaria brown spot

Summary

Introduction

In Brazil new varieties of citrus were selected along the years, but none sensory analysis is usually made to verify the acceptance as one of the bottleneck for fresh citrus juice industry and before the commercial release. Pera sweet orange is the most notable variety consumed in Brazil with appropriate values of 11.8 °Brix, 51% of juice yield, 12.5 for ratio, approximately 1.14g/100mL of acidity, and variable mass of 145g (Salibe, 2002; Pio, 2005; CEAGESP, 2009; Couto & Canniatti-Brazaca, 2010). Another two important varieties are Murcott tangor and Cravo mandarin with adequate quality values established respectively: 12.6 and 10.8o Brix, 48% of juice yield for both, 13.7 and 13.5 for ratio, acidity of 0.92 g/100mL and 0.8 g/100mL and middle-weight of 140 g and 135 g (Teófilo et al, 2001; Pio, 2005). The responses given by consumers in sensory analysis are derived from the behavior (psychological characteristics) and stimuli (physical and chemical characteristics) that the product offers to them, which determine the sensations and interpretation of product properties (Rodas & Torre, 2008)
