“…Sunburn damage was reduced from 21.9% in untreated control to 9.4% in Surround WP‐treated fruits . Yazici and Kaynak reported that fruit surface temperatures that cause sunburn vary between 41 and 47.5 °C and kaolin treatment proved to be the best method to reduce sunburn injury in ‘Hicaznar’ cultivar. Sunburn incidence varies with the cultivar and season.…”

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.

“…The cause of sunburn is the combined action of high solar radiation, low humidity and high temperatures. Yazici and Kaynak (2006) reported that fruit surface temperatures that cause sunburn vary between 41 °C and 47.5 °C and kaolin treatment proved to be the best method to reduce sunburn injury in 'Hicaznar' cultivar. Holland et al (2009) reported that in Israel, late cultivars such as 'Wonderful' are much more susceptible to sunburn than early cultivars such as 'Akko' and 'Shani-Yonay'.…”

Postharvest Biology and Technology of Tropical and Subtropical Fruits

During the past decade, research and development activities on pomegranate fruit were focused on the application of new postharvest storage technologies to extend the storage life and keeping the original quality of the freshly harvested fruits. These technologies included use of fungicides to control decay, and modifi ed atmosphere packaging or controlled atmosphere storage to maintain postharvest quality and to alleviate chilling injury symptoms which occur during the storage of pomegranates below 5-7 °C, depending on the variety and storage duration. Today, consumption of fresh pomegranates and their juice is booming due to the mounting evidence about their health benefi ts. Pomegranate juice processing allows the use of fruits with external defects that do not infl uence aril quality. These fruits and the remaining tissues after juice extraction may be used for preparation of new products, such as fl avonoids capsules and other nutraceuticals. This chapter provides an overview of postharvest biology and technology of pomegranates in relation to maintaining their quality between harvest and fresh consumption or processing.

“…Many research reports highlight the favorable effect of kaolin on sunburn, such as in the case of pomegranate, apple, walnut, citrus fruits and tomato Cantore et al, 2009;Glenn, 2012;Pace et al, 2007;Saavedra Del et al, 2006;Weerakkody et al, 2010). The reduction in crop temperature with the application of kaolin can increase the average fruit weight (Cantore et al, 2009;Lalancette et al, 2005;Saleh and El-Ashry, 2006) and improve some fruit properties, such as color, total soluble solids, vitamin C content, and anthocyanin concentration (Chamchaiyaporn et al, 2013;Glenn et al, 2001;Melgarejo et al, 2004;King, 2013a, 2013b;Wand et al, 2006;Yazici and Kaynak, 2009). It should be noted that kaolin is a natural substance, used in organic farming, such that treated crops can readily be consumed.…”

a b s t r a c tModern agriculture is faced with two tasks: (1) to produce enough food for a growing global population, and (2) to ensure satisfactory crop quality while using water resources efficiently. A study of the effect of kaolin on the yield, quality and water use efficiency of tomato (Lycopersicon esculentum Mill.), grown under different irrigation regimes, is reported in the paper. The research was conducted in an open field with carbonate chernozem soil, at Stara Pazova (40 km north of Belgrade, Serbia). It lasted for three years (2011, 2012, and 2013). The experimental setup was a two-factorial, completely random block system, with three replications. The first factor was the irrigation regime and the second the application of kaolin. Two irrigation treatments were studied: (a) full irrigation (F), covering 100% of ETc (crop evapotranspiration), and (b) deficit irrigation (D) at 50% of ETc. The kaolin treatments were: (a) control treatment, without kaolin (C) and treatment with a 5% suspension of kaolin (K).On average, the highest fresh tomato fruit yields were achieved under full irrigation, with kaolin (FK) (21.0 kg m −2 ). The FK treatment also resulted in the greatest dry weight of the fruits (1.1 kg m −2 ). The average fruit weight was rather uniform and ranged from 71.7 g with DC to 75.4 g with DK. The average sugar and lycopene content was quite uniform over the study period, while the irrigation regime had a significant effect on the average organic acid content and total antioxidant activity. Deficit irrigation treatments resulted in a higher organic acid content and higher total antioxidant activity than full irrigation. The application of kaolin had a greater effect of the water use efficiency of tomato than the irrigation treatment.
