Alternative Methods of Bioactive Compounds and Oils Extraction from Berry Fruit By-Products—A Review

Berry fruit by-products are a source of polyphenol compounds and highly nutritious oils can be reused to fulfill the requirements circular economy model. One methods obtaining polyphenol-rich extracts or is extraction. Applying conventional solvent extraction techniques may insufficient reach high lipid fraction yields selectivity specific compounds. Alternative methods, mainly ultrasound-assisted extraction, pulsed electric field-assisted microwave-assisted supercritical fluid ways improve efficiency isolation bioactive from berry by-products. Additionally, non-conventional considered as green they consume less energy, volume time. The aim this review summarize studies on alternative their relationship composition obtained waste products.
