Apple pomace is a significant by-product generated during the making of apple juice. It is frequently discarded as waste, harming the environment and making it risky for people’s health. The primary goals of this narrative review are to discuss the composition, functional bioactives, extraction techniques, and current food applications of apple pomace. Given the immediate positive economic effects, higher yields from novel extraction techniques were determined to be paramount. In addition to bioactive substances, apple pomace has a high dietary fiber content that could be utilized in newly created formulations. Additionally, this pomace can be added to food products to increase their nutritional content and marketability. For example, adding apple pomace to bread, confectionery, dairy, and meat products has increased their nutritional value and phytochemical and health-promoting qualities. Furthermore, the limitations associated with using this by-product in those products are addressed in this investigation. It is expected that the data presented in this work will serve as a helpful reference for food industry professionals in proposing an economical and sustainable extraction method that will convert apple waste into a functional product with added value. Along with validating potential bioactivity, additional research is required to determine the stability of bioactive substances and the mechanisms that regulate them.
