概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
A breakthrough for antifungal coating production through hydroxypropyl cellulose (HPC), lauric arginate (charged emulsifier) (LAE), and cinnamaldehyde (CDH) was developed. It was made from 2% HPC, 0.2% LAE and 0.3% CDH. The incorporation of LAE and may improve the performance of HPC antifungal activities additively confirmed with a series of assays (in vitro, in vivo, and membrane integrity changes)
実験 / Experimental
Each coating solution was measured for zeta potential value by using a Zetasizer (Zetasizer Nano ZNP, Malvern Instruments, UK) with five replications.
結果と考察 / Results and Discussion
Zeta potential value of all coating solutions showed negatively charged surfaces ( -1.31 for HPC, and -3.24 for HPC/CDH), except for HPC/CDH containing LAE (10.47).. Theoretically, zeta potential value more than ±30 mV (negative or positive) represented the physically stable dispersions as the result of electrostatic repulsion (Kringel et al., 2019). The addition of LAE increased zeta potential value of Chi dramatically (P
