“…Several studies have been carried out to understand the effect of their addition to the diet of different animals such as broiler chickens and mammals on their antioxidant defense. Gerasopoulos and Petrotos (2022) analyzed the distribution of fatty acids in plasma and tissues of piglets alimented with feed containing polyphenols extracted from OMWW. The addition of polyphenols to the piglets feed allowed a decrease in omega-6/omega-3 ratio, which leads to more omega-3 fatty acids in the meat of pigs.…”

Olive oil extraction has recently experienced a continuous increase due to its related beneficial properties. Consequently, large amounts of olive mill wastes (OMWs) derived from the trituration process are annually produced, causing serious environmental problems. The limited financial capabilities of olive mills make them usually unable to bear the high costs required for the disposal of their wastes. Alternatively, the valorization of OMWs within the framework of the so-called waste-to-resource concept and their recycling can represent a successful strategy for the implementation of circular economy model in the olive industry, which could have significant socioeconomic impacts on low-income Mediterranean countries. There is, however, no unique solution for OMWs valorization, due to the wide variety of the wastes’ composition and their seasonal production. In this review, the potential of OMWs for being reused and the recent technological advances in the field of OMWs valorization are assessed. Special focus is given to the analysis of the advantages and limitations of each technology and to reporting the most significant issues that still limiting its industrial scale-up. The information collected in this review shows that OMW could be effectively exploited in several sectors, including energy production and agriculture. OMWs potential seems, however, undervalued, and the implementation of sustainable valorization strategies in large-scale remains challenging. More efforts and policy actions, through collective actions, encouraging subsidies, and establishing public–private collaborations, are still needed to reconcile research progress with industrial practices and encourage the large-scale implementation of the waste-to-resource concept in the olive sector.

“…Interestingly, these food processing wastes and by‐products are sources of aromatic compounds (fruit pomace and spices pods), pigments (fruits and vegetable peels), polyphenols (fruits and vegetable seeds and peels, milling sewage), proteins (animal bones) and lipids (fish offal) which are known as bioactive compounds. Bioactive compounds are the extra nutritional compounds present in certain plants and animals which give health benefits through their antioxidant activity and therapeutic properties (Shen et al ., 2019; Sharmila et al ., 2020; Capanoglu et al ., 2022; Gerasopoulos & Petrotos, 2022). Extracted bioactive compounds from food processing wastes or by‐products have wide applications in food industries as preservatives, anti‐browning agents, thickeners and colouring agents (Carocho et al ., 2018; Dias et al ., 2020; Vilas‐Boas et al ., 2021).…”

Food processing is an emerging industrial sector that applies new technologies to process foods efficiently. During processing, food industries produce a substantial amount of by-products as waste. Disposal of these wastes remains a problem and causes environmental pollution and greenhouse gas emissions. However, novel food processing technology like pulsed electric field-assisted extraction (PEFAE) has the potential to utilise these wastes as a source of bioactive compounds and extract valuable compounds in a shorter period with minimal use of solvents and energy. This review covers the basics of pulsed electric field (PEF) and its effect on bioactive compound extraction yield and quality. Furthermore, the article compares the PEF treatment energy and extraction efficiency with other non-conventional extraction methods to better make the reader understand in terms of selecting the suitable processing method. However, the extraction yield and process efficiency depend highly on the processing parameters. Hence, the article also explains the various kinetic models involved in PEF-assisted food waste valorisation to control the process parameters during treatment.

“…Even though they constitute a small portion of food sources, these compounds can activate mechanisms that alter and enhance human health [10]. Bioactive compounds offer additional health benefits via antioxidant activity and therapeutic properties [11][12][13][14]. Some of these compounds, with proven health advantages like antihypertensive, anti-cancer, antioxidant, and anti-tumor properties, are utilized in drug formulation within the pharmaceutical industry [3,15].…”

The food processing industry is a continuously developing sector that uses innovative technologies to efficiently process food products. During processing, food industries generate substantial amounts of by-products in the form of waste materials. This food waste consists of organic matter rich in bioactive compounds, such as polyphenols, carotenoids, and flavonoids. Improper management of food waste can adversely affect both the environment and human health, leading to environmental pollution and the release of greenhouse gas emissions. Thus, proper food waste management has become an urgent global issue. The presence of bioactive compounds (mainly polyphenols, flavonoids, and anthocyanins, but also carotenoids, alkaloids, proteins, lipids, and carbohydrates) in food waste holds the potential to transform them into valuable resources. Several sectors, including food and energy, have recognized food waste as an innovative source. Recently, much emphasis has been placed on optimizing the extraction yield of such bioactive compounds through the utilization of environmentally friendly and sustainable methodologies and solvents. Pulsed electric field (PEF)-assisted extraction is an emerging technique that holds promise for the utilization of waste materials. PEF technology can efficiently optimize the extraction of valuable compounds within a shorter time while minimizing solvent and energy consumption. In this review, we provide a comprehensive overview of the current state of PEF technology and its implications for recovering bioactive compounds from food waste. The integration of innovative technologies like PEF in the food processing industry can play a crucial role in managing food waste sustainably, reducing environmental impact, and harnessing the full potential of bioactive compounds contained in these waste materials. The objective of this critical review is to provide an overview of the utilization of PEF pretreatment for food by-products and to conduct a comparative analysis with other extraction techniques.
