“…Although to a minor extent, Italian and Israeli genotypes showed similar differences for the juice color, and in general the juice of the Israeli pomegranates was of a more intense red (Table 4). Colorimetric parameters did not show significant differences between the two years, with the only exception of C* which was higher in 2012 with respect to 2013 (48.4 vs. 46.5) and these data are in agreement with previous work on 'Mollar de Elche', when a very little variability of the three colorimetric coordinates, L*, a* and b* was detected during different years (Manera et al, 2013). This also seemed to suggest that colorimetric parameters may be very useful to distinguish cultivars of different origin, Italy and Israel in the case of our research.…”

“…From the L∗, a∗ and b∗ values, other colour indexes that have been previously evaluated were calculated using the following Eqs. (1) , (2) , (3) , (4) , (5) , and (6) to enhance the sensitivity of the colour evaluation [ 22 , 23 , 24 , 25 ]:

Background Marketing strategies, such as branding, redefine how consumers perceive quality and create new requirements related to season length and quality homogeneity, among others. For short-day (SD) strawberry cultivar brands, the commercial season is short due to a dependency on temperature and photoperiod. A plausible strategy to extend the commercialization period is to use different varieties within a single brand; however, this has led to inconsistent quality in other fruit crops. A form of quality assessment to evaluate the impact of a multi-varietal brand on sensory quality is a critical longitudinal study with several sources of variability, such as the inherent variation among assessors and fruit replicates that can affect the reliability of the results. Therefore, this study aimed to develop a methodology to assess the sensorial and physicochemical quality of strawberry brands in two contexts: a short-term season composed of two SD cultivars and a long-term season with one SD and one day-neutral (DN) cultivar. Results New statistical models are proposed in this study. An ANOVA mixed model with assessors and replicates as random terms and a multiple factor analysis highlighted a lack of homogeneity with regard to texture parameters and sourness, while partial least square models identified aroma and sweetness as the best quality indicators. Conclusions This work has successfully illustrated a methodology that is capable of handling critical aspects of longitudinal studies by using univariate models that account for different sources of variability and constrained multivariate models to relate parameters with overall liking. A long-term brand is a viable solution to valorise strawberries, as parameter heterogeneity did not affect overall quality.

“…According to earlier studies, the red colour of apricots seemed to catch consumer's eyes and contributed to visual appearance (Fan, Zhao, Wang, Cao, & Jiang, 2017). Therefore, deriving from L*, a* and b*, other colour indexes previously tested were calculated in order to enhance sensitiveness of colour evaluation (Cristina, 2014;Manera et al, 2013;Pathare, Opara, & Al-Said, 2013):…”

Few studies have investigated sensory quality in multi-varietal fruit brands due to challenges in making comparisons between varieties harvested sequentially throughout the season. Sensory data are collected in crisp form and analysed using a great amount of numerical data. However, human perception is vague and an assessor's opinion comes in linguistic form. The purpose was to assess the sensory quality of branded apricot using a novel statistical approach. Physicochemical and sensory attributes were determined for two consecutive commercial seasons. Univariate and multivariate models were applied in order to assess quality stability and to create a prediction model. The brand was affected by the presence of different cultivars and the multiple factor analysis demonstrated aroma and juiciness as the most differentiated parameters, while univariate analysis highlighted hardness and mealiness. Use of expert knowledge mixed with information from sample data enabled the development of a fuzzy model. Investigation with consumer test is needed.Novedoso enfoque estadístico para evaluar la calidad y la viabilidad comercial de una fruta perecedera de marca minorista RESUMEN Pocos estudios han investigado la calidad sensorial en marcas de frutas de múltiples variedades debido a las dificultades para realizar comparaciones entre variedades cosechadas de forma secuencial a lo largo de una temporada. Generalmente, los datos sensoriales se recopilan de forma precisa y se analizan utilizando una gran cantidad de datos numéricos. Sin embargo, la percepción humana suele ser vaga y la opinión del evaluador se presenta en forma lingüística. El propósito del presente estudio fue evaluar la calidad sensorial del albaricoque [durazno] de marca empleando un enfoque estadístico novedoso. Así, durante dos temporadas comerciales consecutivas se determinaron los atributos fisicoquímicos y sensoriales de los albaricoques. Para ello se aplicaron modelos univariados y multivariados con el fin de evaluar la estabilidad de la calidad y crear un modelo de predicción. Se constató que la marca se vio afectada por el uso de diferentes cultivares; en este sentido el análisis factorial múltiple demostró que el aroma y la jugosidad son los parámetros de la fruta que más se diferencian, mientras que el análisis univariado destacó la dureza y la consistencia harinosa de la fruta. El uso de conocimiento experto combinado con la información proveniente de los datos de muestra permitió desarrollar un modelo difuso. Es necesario realizar investigaciones que incluyan pruebas entre consumidores.
