Antibacterial activity of capsaicin-coated wool fabric

Abstract

Fabrics made from natural fibers, such as wool and cotton, are susceptible to attacks from micro-organisms, which may damage the fabrics and harm the human body. Antimicrobial finishing of natural textile products may involve harmful and non-environmentally friendly chemicals. In this study, a natural antibacterial agent, capsaicin, was coated on the surface of wool fabrics by a sol-gel process. The antibacterial properties of coated fabrics were evaluated against test bacteria Escherichia coli according to the American Association of Textile Chemists and Colorists (AATCC) method and standard American Society for Testing and Materials (ASTM) E2149-01. Compared with the control group (sol-gel coated fabric without capsaicin), the capsaicin-coated fabric inhibited bacterial growth markedly after 24 hours incubation at 37 C. The antibacterial efficiency after laundry washes was also investigated. Good durability to washing of capsaicin on fabric was achieved by the sol-gel coating technique.

Capsicum annuum(hot pepper): An ancient Latin‐American crop with outstanding bioactive compounds and nutraceutical potential. A review

“…Antifungal potential has been attributed to capsaicin, mainly against Penicillium expansum, Trametes versicolor, and Gloeophyllum trabeum. On the other hand, it can be used to treat some viral infections like herpes simplex virus (HSV) disease in guinea pigs, HSV infections, and genital herpes (Akhtar et al, 2017;Liu, Lin, Peng, & Wang, 2012;Marini, Magi, Mingoia, Pugnaloni, & Facinelli, 2015). Likewise, Nazzaro et al (2009) suggested that pepper products could be used to develop new antimicrobial agents for food preservation, to control foodborne pathogens in foods and/or product spoilage avoiding the use of synthetic preservatives.…”

Preparation of poly[3-(methacryloylamino) propyl] trimethylammonium chloride coated mesh for oil–water separation

“…The antimicrobial activity was assessed referring to the standard shake flask method (ASTM-E2149-01) [43][44][45][46][47], which could determine the antimicrobial activity. This method provides quantitative data for measuring the reduction rate in a number of colonies formed, converted to the average colony forming units per milliliter of buffer solution in the flask (CFU/mL).…”

Cyclic voltammetric determination of capsaicin by using electrochemically deposited tin and reduced graphene oxide on screen-printed carbon electrodes

“…Capsaicin has been widely used in pharmaceutical and medical applications due to its remarkable properties, such as boosting metabolism to increase amount of heat in body and burn more calories [7], reducing blood pressure [8], helping dilation of blood vessel [9], and improving blood circulation [10]. Capsaicin also has antioxidative [11], antibacterial [12] and anticarcinogenic [13] properties.…”
