ABSTRACT
Pecan nut (Carya illinoensis K.) is an economically important tree due to the fruit that it produces. It has been reported that extracts of some parts of the tree, like the leaves, husk, and shell of the fruit, has antimicrobial properties. Because of this it is possible to develop a green technology to extract natural antimicrobial agents such as polyphenols that has potential application in food industries as antimicrobials that permits substitute synthetic antimicrobials for natural ones. Leaves, husk, and shell of pecan nut were collected by a community in Parras de la Fuente, Coahuila, Mexico, and phenolic extracts were obtained by water heating, ohmic heating, and microwave at 40°C, 60°C, and 80°C, respectively, by 20 min for each sample. Obtained extracts were tested against Escherichia coli and Staphylococcus aureus. Present work demonstrates that extracts obtained by green technologies (ohmic and microwave) are more effective to inhibit growth of E. coli and S. aureus.
