Cultivar affects browning susceptibility of freshly cut star fruit slices

Abstract: Consumption of freshly-cut horticultural products has increased in the last few years. The principal restraint to using freshly-cut carambola is its susceptibility to tissue-browning, due to polyphenol oxidase-mediated oxidation of phenolic compounds present in the tissue. The current study investigated the susceptibility to browning of star fruit slices (Averrhoa carambola L.) of seven genotypes (Hart, Golden Star, Taen-ma, Nota-10, Malásia, Arkin, and Fwang Tung). Cultivar susceptibility to browning as measu… Show more

“…1 and the data (L* or a*) in Table 1, the polarities of the most highly active components with relatively high stability should be equivalent to that of ethanol, which was further supported by the phenomena that higher active components were eluted faster than other in silicon column, when taking MRP (EtOH) as the starting material (data not shown). It should be noted that the browning degree in endocarp of banana slices was obviously higher than mesocarp, which was consistent with the previous report in apple slices (Lunadei et al 2011) and star fruits slices (Teixeira et al 2006), probably due to the high location of PPO or its substrates in the endocarp. Besides, the b* value increased and then decreased for banana slices treated by MRP or H 2 O, but it trended to decrease in the case of Na 2 S 2 O 5 .…”

“…The changes of luminosity (L value) must be due to caramelization of the sugar in dragon fruit peel or a Maillard reaction causing browning during drying [31,32]. On the other hand, the a and b values of fresh peel were higher than drum-dried powder, indicating degradation of the red and yellow compounds in fresh peel during drum drying.…”

“…Foram utilizadas carambolas da cultivar Malásia, por ser o material predominante da região de Vista Alegre do Alto-SP; da 'Hart', por apresentarem menor escurecimento (Teixeira et al, 2006); e da 'Nota 10' por ser fitotecnicamente muito promissora (Silva, J.A.A., 2006 Informação pessoal). Os frutos utilizados foram colhidos no pomar da Estação Experimental de Citricultura de Bebedouro, São Paulo, no estádio de maturação "verde-maduro", ou seja, com metade de sua coloração amarela (Teixeira, 2005 C, e drenadas por 3 minutos e, em seguida, porções de aproximadamente 300 g. foram acondicionadas em bandejas de polietileno tereftalato (PET) da Neoform ® modelo N-90, com capacidade para 500 mL, transparentes e providas de tampa encaixável, antes de serem armazenados a 10,3±1°C e 80±5% UR.…”

“…As cultivares Fwang Tung, Hart e Golden Star são naturalmente mais claras, ou seja, possuem coloração mais esbranquiçada, quando comparadas com outras mais amarelo-alaranjadas, 'Taen-ma', 'Nota-10', 'Malásia' e 'Arkin' (Teixeira et al, 2006).…”
