CAROLINA PAZOS, MARIA D ALBA This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-8722570/v1 This work is licensed under a CC BY 4.0 License Status: Under Review Version 1 posted 5 You are reading this latest preprint version Abstract The essential oil (EO) of thyme ( Thymus vulgaris ) exhibits antifungal and antimicrobial properties. Its high concentration of terpenes, such as thymol, provides them with great effectiveness as a fungicide, particularly against fungi such as Moniliophthora roreri , a cocoa pathogen. However, its potential application as an organic fungicide is limited by the photostability and volatilization of essential oils. Thus, the use of carriers for the extract has been the aim of this research. In this study, the adsorption-desorption process of thymol has been evaluated in calcium alginate-bentonite microcapsules and the bentonite-chitosan composite as EO carriers. The results have shown that the maximum adsorption capacity was higher for the microcapsules than for the organoclays. However, the desorption percentages indicated that organoclays showed the most adequate release. Finally, the water activity values generated by both bioformulations were below 0.6, indicating that carriers can reduce the probability of microbial growth.
