“…The main physiological factor that impact negatively during storage and marketing is water loss, which is evaluated by weight loss (Smith et al, 2006;Raffo et al, 2007). Weight loss changes between treatments were observed.…”

“…By contrast, whole green fruit regardless of radiation treatment had the lowest weight loss (2.21%), although the differences with the other treatments were not significant. Raffo et al (2007) found that fruit pepper is susceptible to serious loss of water due to high area/volume ratio, although these losses are substantially reduced in plastic packaging. According to Gonzalez-Aguilar and Tiznado (1993), the first symptoms of wilt appear from weight loss of 5% of the initial fruit weight.…”

“…Sugars represent the main fraction of total soluble solids of the fruit, reaching almost 60% of dry matter in red pepper (Raffo et al, 2007). Soluble solids loss during storage is normal because of cellular respiration in postharvest (Özden and Bayindirli, 2002).…”

The aim of this study was to evaluate the effect of two light environments on two maturity stages of sweet pepper and the postharvest behavior of minimally processed product using passive modified atmosphere. The size and fruit morphology were measured at harvest. Overall visual quality, gas concentration inside the bags, weight loss, soluble solids, firmness, electrolyte leakage, carotenoids and ascorbic acid were determined during the storage period. Results showed that quality parameters were affected by radiation and processing. Shaded pepper fruits showed higher water content and lower size compared to fruits exposed to full radiation. Fruit nutritional value was maintained, but after six days was not marketable. Visual quality of intact fruit was not affected without differences between treatments. Shelf life processed red fruits as julienne was reduced, being the worst performing during storage. Post-harvest visual quality was in relation to gases composition (O 2 and CO 2 ) inside the trays.

A traditional Italian sweet pepper landrace, 'Peperone di Voghera', which faced the risk of extinction, was analyzed for its genetic, phenological, morphological, agronomic and biochemical traits. An extant population was compared with cultivars 'Quadrato d'Asti', 'Cuneo', and 'Giallo d'Asti', cultivated in the same area, in order to evaluate the chance of the landrace recovery. Amplified fragment length polymorphism (AFLP) analysis demonstrated that Voghera landrace is distinct with respect to reference cultivars, thus excluding extensive genetic contamination and providing a molecular basis of both phenological and biochemical differences. Leaf chlorophyll content is lower, fruits start ripening earlier than controls, and yield (1,100-1,300 g plant -1 ) does not significantly differ. Sensitivity to root pathogens, the main factor that led to the decline in the past, does not seem to compromise the future chance of recovery. Vitamin C concentration is high (200-240 mg/100 g) and preserved by cold storage; more than 25% of vitamin C is also kept in pickled fruits. 'Voghera' landrace has nutritional and gastronomic properties that can be appreciated by consumers. The high internal genetic variability shown by AFLP analysis indicates that future selection work is necessary to fully maintain the original traits of the landrace and to improve it.Additional key words: AFLP; biodiversity; Capsicum annuum; extinction; nutraceutical properties; root mycosis. ResumenCaracterización de la variedad de pimiento tradicional 'Voghera', rescatada en el norte de ItaliaEn este trabajo se han analizado las características genéticas, morfológicas, fenológicas, agronómicas y bioquími-cas de una variedad tradicional italiana de pimiento dulce, 'Peperone di Voghera', en peligro de extinción. Se comparó una población existente con cultivares de la misma zona, 'Quadrato d'Asti', 'Cuneo', y 'Giallo d'Asti', a fin de evaluar la posibilidad de recuperarla. Análisis AFLPs (polimorfismos en la longitud de fragmentos amplificados) demostraron que 'Voghera' es distinta con respecto a los cultivares de referencia, lo que excluye que haya una amplia contaminación genética y proporciona una base molecular de las diferencias, tanto fenológicas como bioquímicas. Su contenido en clorofila es menor y los frutos comienzan a madurar antes que los controles, pero el rendimiento (1.100-1.300 g planta -1 ) no es significativamente diferente. Su sensibilidad a patógenos de la raíz, el principal factor que llevó a su declive en el pasado, no parece poner en peligro la posibilidad de una futura recuperación. La concentración en vitamina C es alta (200-240 mg/100 g) y se preserva en el fruto conservado en cámara frigorífica; también se detecta una buena cantidad (más del 25%) de vitamina C en las frutas encurtidas. 'Voghera' tiene propiedades nutritivas y gastronómicas que pueden ser apreciadas por los consumidores. La alta variabilidad genética interna detectada en los análisis AFLP indica que el trabajo de selección es necesario para mantener plena...

The market for processed food is rapidly growing. The industry needs methods for "processing with care" leading to high quality products in order to meet consumers' expectations. Processing influences the quality of the finished product through various factors. In carrot baby food, these are the raw material, the pre-processing and storage treatments as well as the processing conditions. In this study, a quality assessment was performed on baby food made from different pre-processed raw materials. The experiments were carried out under industrial conditions using fresh, frozen and stored organic carrots as raw material. Statistically significant differences were found for sensory attributes among the three autoclaved puree samples (e.g. overall odour F=90.72, p<0.001). Samples processed from frozen carrots show increased moisture content and decrease of several chemical constituents. Biocrystallization identified changes between replications of the cooking. Pre-treatment of raw material has a significant influence on the final quality of the baby food.
