Influence of Photoselective Shade Nettings on Postharvest Quality of Vegetables

2018 Elsevier Inc. All rights reserved. Photoselective shade netting technology is an emerging agrotechnological concept, which aims at combining physical crop protection with different filtrations of solar radiation. They are based on the incorporation of various chromatic additives, light dispersive and reflective elements into the netting materials during manufacturing. Postharvest quality of fresh produce is influenced by environmental conditions that include light, average temperature, minimum temperature, and night-day temperature difference. Photoselective shade nets have been shown to influence yield and quality parameters of fresh produce, their impacts on functional properties of vegetables after postharvest storage has not been fully investigated. Therefore, this chapter illustrates the effect of different colored photoselective shade nets (pearl, red, and yellow) in comparison to the commercially used black net on vegetables, such as tomatoes and sweet overall quality parameters (weight, SSC, and TA), bioactive compounds (ascorbic acid, total phenols, flavonoids, -carotene, and lycopene contents), antioxidant scavenging activity, volatile aroma compounds at harvest and after postharvest storage.
