“…Consumer acceptability for rockmelons (Cucumis melo) is correlated with sugar concentrations at harvest (Lester and Shellie 1992), although the presence of various volatile compounds is also relevant (Yamaguchi et al 1977). Thus, high sugar concentrations do not totally define eating quality; however, the absence of high total soluble solids (TSS) makes good eating quality highly unlikely.…”

Abstract. Near infrared spectroscopy (NIRS) can be used for the on-line, non-invasive assessment of fruit for eating quality attributes such as total soluble solids (TSS). The robustness of multivariate calibration models, based on NIRS in a partial transmittance optical geometry, for the assessment of TSS of intact rockmelons (Cucumis melo) was assessed. The mesocarp TSS was highest around the fruit equator and increased towards the seed cavity. Inner mesocarp TSS levels decreased towards both the proximal and distal ends of the fruit, but more so towards the proximal end. The equatorial region of the fruit was chosen as representative of the fruit for near infrared assessment of TSS. The spectral window for model development was optimised at 695-1045 nm, and the data pre-treatment procedure was optimised to second-derivative absorbance without scatter correction. The 'global' modified partial least squares (MPLS) regression modelling procedure of WINISI (ver. 1.04) was found to be superior with respect to root mean squared error of prediction (RMSEP) and bias for model predictions of TSS across seasons, compared with the 'local' MPLS regression procedure. Updating of the model with samples selected randomly from the independent validation population demonstrated improvement in both RMSEP and bias with addition of approximately 15 samples.

“…A importância do SST na qualidade dos frutos é relatada por Cohen & Hicks (1986), que comprovaram uma forte correlação entre o SST e a aceitação, doçura e aroma. Yamaguchi et al (1977), em estudo sobre a correlação entre análise sensorial e SST em cantaloupe, determinaram outros atributos de qualidade, tais como: firmeza da polpa, aparência (interna e externa) e compostos voláteis.…”

RESUMOCom o objetivo de avaliar a qualidade pós-colheita de dois genótipos de melão amarelo (TSX 32096 e SUNEX 7057) armazenados sob condições ambiente (30,0 ± 1°C e 50,0 ± 5% de umidade relativa), instalou-se experimento em Mossoró (RN), com frutos provenientes do Agropólo Mossoró -Assu, (RN). O clima dessa região é quente e seco, com precipitação pluviométrica de 423 mm, temperatura máxima e mínima de 33 e 29°C, respectivamente. O solo da área experimental é do tipo Podzólico Vermelho-Amarelo Equivalente Eutrófico. Os frutos foram colhidos nas primeiras horas da manhã no estádio de maturação comercial. Imediatamente após a colheita e seleção (frutos com boas características externas de qualidade) os melões foram embalados e transportados para o Laboratório de Análises de Frutos e Hortaliças do Departamento de Química e Tecnologia da Escola Superior de Agricultura de Mossoró, onde foram armazenados à temperatura de 30,0 ± 1°C e 50,0 ± 5% de umidade relativa por até 49 dias. As avaliações foram feitas a intervalos de 7 dias. Montouse o experimento em delineamento inteiramente casualizado em esquema fatorial do tipo 2 x 8 (genótipos x tempo de armazenamento) com 3 repetições, cada parcela composta por 3 frutos. Foram avaliadas as seguintes características: firmeza da polpa, perda de peso, aparência (externa e interna), acidez total titulável, pH, o conteúdo de sólidos solúveis totais, vitamina C total e os açúcares solúveis (redutores, não-redutores e totais). Houve interação significativa entre os fatores estudados (temperatura x tempo de armazenamento) para a firmeza da polpa, aparência interna e teor de açúcares solúveis (redutores, não-redutores e totais). Os resultados revelam aumento regular na perda de peso e um declínio na firmeza da polpa durante o período experimental. Os dois genótipos apresentaram redução na firmeza da polpa e da qualidade externa e interna até o final do período experimental, no entanto, o genótipo TSX 32096 apresentou uma firmeza de polpa mais elevada e uma melhor aparência interna. A firmeza da polpa aos 42 dias de armazenamento foi de 18,40N e 15,38N para os genótipos TSX 32096 e SUNEX 7057, nesta ordem. A perda de peso aos 42 e 49 dias de armazenamento foi de 4,60% e 5,12%, respectivamente. Houve redução da acidez total titulável, do conteúdo de sóli-dos solúveis totais e da vitamina C total para os dois genótipos. O conteúdo de açúcares totais sofreu um acréscimo (variação de 6,8% para 8,2%) e um declínio (variação de 9,5% para 8,8%) durante o armazenamento, para os genótipos TSX 32096 e SUNEX 7057, nesta ordem. De acordo com os dados, os genótipos TSX 32096 e SUNEX 7057 apresentaram uma vida útil pós-colheita de 42 dias sob condições ambiente (30,0 ± 1°C e 50,0 ± 5% de umidade relativa).

“…Flesh firmness has a great effect on eating quality (Beaulieu et al, 2004;Mutton et al, 1981;Yamaguchi et al, 1977). The objective measurement in this study also reveals that the TPA parameters obtained at the stages of best eating quality in each cultivar are not necessarily similar.…”

“…Fruit quality is widely estimated by the soluble solid content (SSC); however, it has been reported that SSC is insufficient as the sole index of eating quality (Aulenbach and Worthington, 1974;Yamaguchi et al, 1977). Another important index of the eating quality in muskmelon is texture.…”

Postharvest modification of flesh firmness and its relationship to pectin solubility were investigated in eight commercial cultivars of muskmelon (Cucumis melo L. var. reticulatus Naud.). A considerable difference in the softening rate was found between cultivars. Relatively rapid softening to desirable texture was found in the flesh of 'Sapporo King ER', 'Melorin', and 'King Melty' within three or four days after harvest. The flesh of 'Ichihime', 'Red 113', and 'G 08' showed slower softening, taking approximately a week to obtain acceptable texture. Especially in 'Ichihime' and 'Red 113', the flesh remained relatively firm even after 14 days. 'Rupia Red' and 'Earl's Knight Shunjukei' showed an intermediate softening rate. These characteristics corresponded to the objective measurement, and a logarithmic relationship was found between sensory scores of flesh firmness and hardness measured by texture analyzer. Furthermore, significant differences between cultivars in the rate of pectin solubilization were observed, which corresponded to the rates of flesh softening. A significant negative correlation was observed between texture analyzer-measured hardness and water-soluble pectin content, which seemed to fit an exponential curve. The hardness for acceptable eating quality varied from cultivar to cultivar. The contribution of this objective method of measuring flesh firmness to the evaluation of eating quality, and its difficulty due to differences in postharvest behavior of cultivars, are discussed.
