Vibroextraction from Pre-treated Amber by Electro-impulse Discharges

Amber, a natural source of succinic acid, essential oils, and various micro- and macroelements, holds great potential for applications across industries. This study investigates the efficacy of electro-impulse pre-treatment in enhancing substance extraction from amber. The results reveal a significant 50% relative discrepancy in organic acid content favoring treatment with a total energy of 250 kJ compared to 125 kJ. Notably, electro-impulse treatment with 312.5 J discharge energy led to a 23% higher total extraction of organic acids, indicating potential benefits for subsequent processes. Furthermore, analysis of pH levels in the extracts aligns with organic acid content, affirming a correlation between these indicators. This study underscores the importance of energy parameters in electro-impulse treatment, providing valuable insights for optimizing amber processing techniques. It suggests that completing treatment with 300 discharges at 312.5 J, followed by vibro-extraction, may yield extracts with significantly higher organic acid content than alternative methods, showcasing a 16% difference in total content. These findings offer a pathway to harnessing the full potential of amber for diverse industrial applications.
