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.
