Іmpact of morphology on D-limonene payload and diffusion in biodegradable prolonged release films
In this study, D-limonene is integrated into films made with different ratios of gelatin to β-CD. The FTIR, vacuum liquid absorption method and gravimetric analysis were used to assess porosity and swelling behavior. Inclusion and retention were detected by FTIR analysis in distinctive peaks at 870–890 cm-1. Films with a 3:1 gelatin to β-CD ratio had a higher D-limonene payload. Porosity and swelling are enhanced with increasing β-CD content.
