Valorization of fruit and vegetable waste for bioactive pigments: extraction and utilization

The aim of this review is to provide comprehensive information about non-thermal technologies applied in fruit and vegetables (F&V) by-products to enhance their phytochemicals and to obtain pectin. Moreover, the potential use of such compounds for food supplementation will also be of particular interest as a relevant and sustainable strategy to increase functional properties. The thermal instability of bioactive compounds, which induces a reduction of the content, has led to research and development during recent decades of non-thermal innovative technologies to preserve such nutraceuticals. Therefore, ultrasounds, light stresses, enzyme assisted treatment, fermentation, electro-technologies and high pressure, among others, have been developed and improved. Scientific evidence of F&V by-products application in food, pharmacologic and cosmetic products, and packaging materials were also found. Among food applications, it could be mentioned as enriched minimally processed fruits, beverages and purees fortification, healthier and “clean label” bakery and confectionary products, intelligent food packaging, and edible coatings. Future investigations should be focused on the optimization of ‘green’ non-thermal and sustainable-technologies on the F&V by-products’ key compounds for the full-utilization of raw material in the food industry.

“…Different phenolic compounds and pigments (e.g., chlorophylls, anthocyanin, betalains, and carotenoids) have been extracted from fruit and vegetable trash (e.g., seeds, peels, or pomace from grapes, tomatoes, and red beet) [20]. These compounds can be used 2 of 17 as food additives, natural colorants, and color intensifiers [21]. Additionally, dietary fiber, phenolic compounds, flavoring agents, aromas, enzymes, and organic acids can be obtained from mango, banana, grape, potato, tomato, garlic, lemon, orange, and carrot residues [22].…”

The reuse and reincorporation of waste are the principles of circular economies. Compost, biofuels, animal feed, dyes, and bioactive compounds can be obtained from the revaluation of organic waste. Research on this subject is scarce and limited to specific sectors, such as agriculture and agroindustry, leaving aside others that generate large quantities of organic waste, such as floriculture. The remains of these sectors have a low decomposition rate compared to other organic wastes. They are a source of bioactive compounds (e.g., essential oils, pigments, phenols) that can be reincorporated into the production chain of various industries. This review describes the composition of waste from agroindustry, agriculture, and floriculture, analyzing their potential revalorization as a source of bioactive compounds and an alternative supply source.
