New Polyunsaturated Alkamides Findings from CONICET Outlined (Antifungal cellulose by capsaicin grafting)

July 1, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Polyunsaturated Alkamides. According to news reporting out of Bahia Blanca, Argentina, by NewsRx editors, research stated, "Cellulose is one of the most abundant materials in nature. Besides its biological function, cellulose can be extracted from the cell wall and used in several industrial applications."

Our news journalists obtained a quote from the research from CONICET, "Thus, it can be used in papers, pharmaceuticals, food, cosmetics and innovative materials such as nanocomposites, packaging, coatings and dispersion technology. With the aim of extending cellulose applications and producing so-called 'smart' materials, new functionality can be introduced by physical or chemical modifications. Taking into account that capsaicin, the active component of chili peppers, is an excellent antifungal agent, a potential new material could be obtained by chemical reaction between this active compound and cellulose. In this work, capsaicin grafting onto cellulose using polycarboxylic acid as linking agent is proposed. The reaction occurrence was corroborated by Fourier transform infrared spectroscopy and UV-Vis spectrophotometry in reflectance mode. Modified cellulose with < 2 wt% of capsaicin shows a strong change in antifungal activity with respect to the unmodified one. This activity was evaluated by the fungal growth inhibition test with two different fungi, Trametes versicolor and Gloeophyllum trabeum."

According to the news editors, the research concluded: "Modified cellulose samples showed a high percentage of fungal growth inhibition, demonstrating the success of the cellulose modification and high antifungal power of the grafting molecule."
