“…And occasionally, a state of metaxenia does occur wherein there are several seeds of different colour within a pomegranate fruit (Levin 2006). The physicochemical properties of pomegranate fruit cultivars grown in different regions have been reported by several researchers (Artés et al 2000a, b;Al-Said et al 2009;Al-Yahyai et al 2009;Opara et al 2009;Zarei et al 2010). The physical properties reported include the fruit weight, whole fruit and aril colour, juice content and juice dry matter content.…”

Ongoing global drive for a healthier diet has led to a rise in demand for convenient and fresh food produce, with high nutritional value and free of additives. Minimally fresh processed fruits and vegetables, satisfies the consumers' perception of a high nutritional quality and convenience produce. Minimally processed fruit and vegetables are susceptible to increased deterioration in quality and microbial infestation due to increase in endogenous enzymatic processes and respiration rate. Modified atmosphere packaging (MAP) technology offers the possibility to retard produce respiration rate and extend the shelf life of fresh produce. However, it is important to correlate the permeability properties of the packing films with the respiration rate of the produce, in order to avoid anaerobic conditions which could lead into fermentation of produce and accumulation of ethanol. Hence, mathematical prediction modelling is now widely applied in the design and development of effective MAP technology in both whole and minimally processed fresh produce. With increasing global interest in postharvest handling and nutrition value of pomegranate, MAP of minimally processed pomegranate arils offers additional innovative tool for optimal use and value addition, including the utilization of lowergrade fruit with superficial peel defects such as; cracks, splits, and sunburnt. This review paper highlights the current status and applications of modified atmosphere packaging in whole fruit and minimally processed pomegranate arils and identifies future prospects.

“…Opara et al reported a weight loss of 3.85% in ‘Halow’ pomegranate stored at 7 °C and 95% RH for 6 weeks, whereas at 21 °C and 65% RH the weight loss was significantly higher (16.42%). The dramatic increase in weight loss at ambient temperature could probably be due to the lower RH during storage resulting in a higher percentage weight loss compared with cold storage.…”

Pomegranate is a subtropical and tropical fruit of great importance from a health point of view. Despite increasing consumer awareness of the health benefits of pomegranate, consumption of the fruit is still limited owing to poor postharvest handling, storage recommendations, short shelf life and quality deterioration during transportation, storage and marketing. The occurrence of physiological disorders such as husk scald, splitting and chilling injury is another challenge reducing marketability and consumer acceptance. Recently, notable work on postharvest biology and technology has been done. Pomegranate is highly sensitive to low-oxygen (<5 kPa) atmospheres, chilling injury and decay. One of the major problems associated with pomegranate fruit is excessive weight loss, which may result in hardening of the husk and browning of the rind and arils. To reduce chilling injury incidence and to extend storability and marketing of pomegranates, good results were obtained with polyamine, heat, salicylic acid, methyl jasmonate or methyl salicylate treatments prior to cold storage. This article reviews the maturity indices, changes during maturation and ripening, postharvest physiology and technology of pomegranate fruit as well as the various postharvest treatments for maintaining fruit quality.

Purpose -The purpose of this study was to characterize fruit properties of pomegranate cultivars grown in South Africa in order to provide information to assist in selecting cultivars for food and industrial purposes, as well as to optimize postharvest handling and processing. Design/methodology/approach -The physical, textural and chemical properties as well as volatile profile and free radical scavenging capacity of eight cultivars (cvs "Acco", "Arakta", "Bhagwa", "Ganesh", "Herskawitz," "Molla de Elche", "Ruby", and "Wonderful") were quantified to demonstrate the diversity among the characters of the commercially grown cultivars. Findings -Statistically significant differences were found between cultivars for most of the evaluated characters, primarily highlighting the genetic diversity among the cultivars. The classification of fruit cultivars based on quality traits (such as size, texture, colour, soluble solids, acidity, juiciness and phenolics) showed the great potential of the cultivars for processing and fresh market. The relationship among these quality traits was analysed by principal component analysis (PCA) resulting in the separation of the investigated cultivars into two groups (cluster 1 ¼ Ruby, Arakta and Ganesh; Class 2 ¼ Bhagwa, Acco and Herskawitz) and two ungrouped cultivars (Molla de Elche and Wonderful). Specific understanding about quality traits of each cultivar was established using the correlation coefficients obtained. Originality/value -This study provides valuable fundamental information that can be useful for commercial and industrial purposes, as well as the development of optimal postharvest handling and processing parameters for the investigated South African grown pomegranate cultivars.
