One of the world's promising sectors is food processing. A huge amount of waste is generated during the handling and value addition of agricultural commodities. So researches focus on extracting valuable compounds from organic waste to increase the economical value. On the other hand, the amount of debris is also reduced, which helps sustainable development and carbon footprints. Extractable compounds can be used as an alternative to synthetic compounds in food applications. For this, Ultrasound-Assisted Extraction (UAE) captures the researcher's attention because of its advantages like less solvent utilization, low-temperature operation, and ecofriendly end products. This review recapitulates the mechanism and the factors affecting the extraction and possibility of compounds extracted from waste. The green separation ultrasound-aided technique has been proven to provide higher extractable compounds. Usage of water as a solvent further reduces environmental and economic problems. By considering all of these advantages, this article discusses the mechanism, elements affecting the extraction, and the effect of combination treatment on properties and the outcome of extraction. It presents the details about the application of the UAE in the valorization of waste compounds.Practical application: Food processing is one of the most promising sectors globally; the agricultural organic waste created by this sector plays a significant part in waste generation. Extracting valuable active compounds from this waste can improve the utilization of natural compounds in other foods, help obtain extra income, and help reuse industrial waste. Ultrasound-assisted extraction is a suitable technology for extracting valuable compounds from organic waste. Optimum process conditions must be identified, which vary based on process conditions and extractable material nature to obtain the maximum extraction.
| INTRODUCTIONThe food industry is one of the fast-growing industries globally, which is the complex, global collective of diverse businesses that supplies most of the food consumed by the world population. This immense growth directly impacts the amount of waste produced from these industries.The production, preparation, and consumption of food generate huge volumes of solid and liquid waste. Around 39% of food processing residues created by the food sector are considered waste (Mirabella et al., 2014). Normally edible and inedible parts generated from industries cannot be minimized because they are unavoidable. Compared to others, seafood, fruit, and vegetable industries contribute a vital role in wastage.The majority of the agri-food wastes are normally used to cater for animals, fuel, or fertilizers. Organic waste from the food industry
