Abstract

The efficient use of waste produced during food processing is crucial for mitigating environmental damage, as well as for enhancing value and diversifying goods. In the future, the proliferation of food processing factories will correspond with population growth, leading to an escalation in food waste and associated waste management issues. The collecting of garbage and its utilization in the manufacture of new products is crucial for human health, environmental degradation, and the national economy. Potatoes (Solanum tuberosum L., Solanaceae) are one of the most important staple crops grown worldwide and play a significant role in both human and animal nutrition. The health-promoting effects of potatoes have been observed in human cell cultures, human clinical studies, and experimental animals, including anti-inflammatory, anti-cancer, hypocholesterolemic, antidiabetic, and anti-obesity properties. In this study, the phenolic content of waste potato pulp obtained from a chip factory was analyzed by HPLC-MS after obtaining an ethanol extract suitable for green chemistry, and the determination of total phenolic content was evaluated. Antioxidant activity was also assessed by the DPPH radical scavenging effect. In the resulting waste pulp, caffeic acid, a phenolic compound, was detected. The total phenolic content, determined to be 134.614 ± 4.167 mg gallic acid equivalent (GAE) per gram of extract, appears to be consistent with the chemical basis of this high antioxidant activity. It was observed that the DPPH free radical scavenging test reached an inhibition level of over 80%. Based on the results obtained, it was concluded that the waste potato pulp from the chip factory has the potential to be recycled.
