“…However, modern eco-compatible technologies offer more efficient strategies to recycle these by-products and reuse them as a sustainable source of different nutrients and highly biologically active compounds, such as amino acids, fatty acids, minerals and carotenoids. [1][2][3] Apart from carotenoids, i.e. lycopene and β-carotene found in major amounts, tomato by-products are also rich in phenolic compounds.…”

“…lycopene and β-carotene found in major amounts, tomato by-products are also rich in phenolic compounds. 2,[4][5][6] Variations in chemistry of phenolic compounds in fruits, vegetables and agri-industrial wastes are related to different proportions of simple and complex phenols, such as benzoic and cinnamic acids, coumarins, tannins, lignins, lignans and flavonoids. 7 These diverse forms of phenolic compounds show variable responses to different extraction conditions.…”

This study describes the application of microwave-assisted extraction (MAE) as an innovative technique for isolation of polyphenols from tomato peel waste. Effects of solvents, temperatures (25, 55 and 90 °C) and times (5 and 10 min) were evaluated with regard to total phenols (TP), total flavonoids (TF) and phenolic compound contents. Tomato peel extracts contain high amounts of kaemferol-3-O-rutinoside (8.5 to 142.5 mg kg -1 ), p-coumaric acid (3 to 111.5 mg kg -1 ) and chlorogenic acid derivative (10.5 to 109 mg kg -1 ). Results revealed that extraction time has no significant (p > 0.05) influence on TP, TF and phenolic compounds recovery (exception is cis-p-coumaric acid hexoside). On the other hand, the influence of temperature and chosen solvent on polyphenols yield is significant. Considering interest of consumers to intake natural compounds exhibiting antioxidant properties, this work suggests that tomato peel waste can be used as one of sustainable resources for polyphenols production by MAE.

“…Fruits from the deciduous trees of the genus Prunus, such as Prunus persica (peach), P. armeniaca (apricot) and P. avium or P. cerasus (sweet and sour cherry, respectively) are also classified as drupes; they are often called stone fruits because the shell of the endocarp that encloses their kernels or seeds is hard like a stone [46]. Peach (including nectarine), apricot and sour cherry are the main types of stone fruits that are currently processed in Greece for the production of canned fruits (halves, dices and slices), fruit cocktails, and compotes but also for juices and puree concentrates [47]. Figure 4 shows the general schemes for processing fresh stone fruits in Greece.…”

The Potential of Tree Fruit Stone and Seed Wastes in Greece as Sources of Bioactive Ingredients

2018

The inedible part (stones, husks, kernels, seeds) of the tree fruits that are currently processed in various regions of Greece constitutes a huge portion of the fruit processing solid waste that remains underexploited. In this review, the existing scientific background for the composition and content of fruit stone and seed in bioactive ingredients is highlighted for olives, stone fruits and citrus fruits that represent the economically most important tree crop products of the country. The content of bioactive compounds may vary considerably depending on the quality of the raw material and the treatment during processing. However, both the hydrophilic and the lipophilic fractions of the seeds contain significant amounts of the primary and the secondary plant metabolites. Among them, phytosterols and several types of polyphenols, but also squalene, tocopherols and some other terpenoids with a unique structure are of particular importance for the utilization and valorization of stones and seeds. Official and scholar records about the current management practices are also presented to highlight the dynamics of the Greek fruit sector. Prospects for the regionalization of fruit seed wastes, in line with EU-promoted Research and Innovation Strategies (RIS) for Smart Specialization are critically discussed.

“…Fruit solid wastes typically contain high moisture content (80 -90 wt %) and high concentration of sugars and carbohydrates, making these valuable feedstock for the two-step approach. Fruit wastewaters, like wastewaters from the potato processing industry, contain low organic loads (COD: 2 -5 g L -1 ), but are produced in quantities of 50 -300 m 3 h -1 [72].…”
