| dc.description.abstract | Introduction: Tomato based products is one of the worldwide major agroindustrial sectors generating substantial amounts of wastes, with high economic and environmental costs. These agroindustrial by-products e.g. skins and pulp remnants, are rich in bioactive compounds such as polyphenols. Current extraction treatments, besides representing environmental hazards, may cause these by-products bioactive compounds degradation, promote toxicity, and reduce biological properties and health benefits, thus hampering their added value. Therefore, there is a growing interest in alternative extraction technologies, such as the case of Ohmic Heating (OH), an environmentally-friendly technique (i.e. use of electrical energy) [5]. This study aimed to optimize the extraction of phenolic compounds, antioxidants and carotenoids of tomato wastes through ohmic heating, as an alternative extraction technology. Conclusions: The highest phenolic compounds content and the highest level of antioxidant activity was achieved when tomato wastes were heated for 15 min at 70 °C with 70% of ethanol. OH shows to have a high potential as an environmentally-friendly, economic and fast process for the recovery of polyphenols from industrial tomato by-products. | eng |
