Abstract
Currently, industrial potato processing waste recycling and re–use is an important topic in the food industry, but no actual processing facilities could be found at the moment of this study. The main aim of present research was to develop a method that could, potentially, be practically applicable for industrial potato peel waste recycling into encapsulated phenolic compounds (fine powder), with a further approbation as an antioxidant for ground pork meat. Potato peel wastes were collected from the local potato processing facility, homogenized in the solvent media, and two accelerated extraction technologies (microwave assisted (MAE) and ultrasound accelerated extractions) were applied for the extraction of biologically active compounds and encapsulation wall material. Produced extracts were concentrated (recovered solvent had been collected and reused) and directed for spray-drying. In general, MAE alone showed higher extraction yields than in combinations with ultrasound treatment. Extracts reached maximal biologically active compound concentrations (and were possessing highest radical scavenging activities) after 10 min of MAE treatment. Produced capsules (food grade antioxidant) inhibited ground pork meat lipid oxidation during the storage study at accelerated oxidation conditions. Acquired results form a basis for development of a potato peel industrial scale processing technology.
