“…It is an important component of the plant cell wall, and binds together the strands of pectin helping to maintain fruit firmness. Calcium binding to cell wall components may also reduce the accessibility of cell wall degrading enzymes to their substrates [Vicente et al 2009] and by this way storage and shelf life of fruits can be enhanced. Preharvest calcium sprays are one of the most important practices of the new strategies applied in the Integrated Fruit Production systems [Manganaris et al 2005], improving fruit characteristics and minimizing fungicide sprays towards the end of the harvest period [Sabir et al 2014], since they enhance fruit resistance to brown rot [Conway et al 1994].…”

Demand for fresh grape is increasing globally in accordance with the improvement in living standard since the grape berry contains large amounts of phytochemicals including anthocyanins, phenolics, flavonoids and resveratrol, which have been suggested to be responsible for human health benefits. However, table grapes easily undergo deterioration due to their soft texture and the high water content, which make it difficult to preserve without treatment. This study was thus conducted to evaluate the effect of preharvest calcium sprays on maintenance of postharvest quality of grapes (V. vinifera L. cv. 'Thompson Seedless'). Three preharvest calcium sprays were applied to leaves and developing green berries with or without leaf removal pruning (a traditional practice performed in commercial vineyards worldwide) during berry development stages. After harvest, grapes were cold stored (1°C, 90% R.H.) up to 3 months. Preharvest micronized calcium sprays, with or without leaf removal pruning, markedly extended the postharvest quality of grapes by delaying weight loss, reducing decay, maintaining rachis chlorophyll concentrations and preserving visual quality during the prolonged cold storage. Besides, in calcite-treated grapes, lower titratable acidity decrease courses with a subsequent lower maturity index during prolonged storage indicate that calcite sprays restricted postharvest physiological senescence of grapes. Overall findings indicated that preharvest calcite sprays may be an environmental-friendly, healthy and sustainable viticulture practice for extending postharvest quality of grapes.

“…Heat processing, moreover, leads to the degradation and/or isomerization of most of the chemical compounds. Due to the complexity of the matrices, some chemical compounds are chosen as markers of nutritional quality [32]. For fruit and vegetables, ascorbic acid, carotenoids, vitamin E and phenolic content are generally used as markers.…”

Monitoring and Optimization of the Process of Drying Fruits and Vegetables Using Computer Vision: A Review

et al. 2017

An overview is given regarding the most recent use of non-destructive techniques during drying used to monitor quality changes in fruits and vegetables. Quality changes were commonly investigated in order to improve the sensory properties (i.e., appearance, texture, flavor and aroma), nutritive values, chemical constituents and mechanical properties of drying products. The application of single-point spectroscopy coupled with drying was discussed by virtue of its potentiality to improve the overall efficiency of the process. With a similar purpose, the implementation of a machine vision (MV) system used to inspect foods during drying was investigated; MV, indeed, can easily monitor physical changes (e.g., color, size, texture and shape) in fruits and vegetables during the drying process. Hyperspectral imaging spectroscopy is a sophisticated technology since it is able to combine the advantages of spectroscopy and machine vision. As a consequence, its application to drying of fruits and vegetables was reviewed. Finally, attention was focused on the implementation of sensors in an on-line process based on the technologies mentioned above. This is a necessary step in order to turn the conventional dryer into a smart dryer, which is a more sustainable way to produce high quality dried fruits and vegetables.

“…Many of these compounds (mainly carotenoids, phenolics and some vitamins) have shown antioxidant activity. It is well established that the consumption of fruits and vegetables has been associated with reduced risk of developing chronic diseases (Holst and Williamson, 2008;Vicente et al, 2009;Yahia 2010). The plant secondary metabolites, antioxidants and phenolics components commonly found in various vegetables provide a fruitful defence…”
