Effect of a New Microchip Spiral Tube Device on the Shelf Life of a Food Model in the Presence of Escherichia coli

The objective of this study was to determine the antimicrobial/suppressing effect of a new microchip spiral device to extend the shelf life of a food model in the presence of Escherichia coli.

In order to demonstrate the suppressing effect of the microchip technology on microorganisms, 0.1% peptone water inoculated with Escherichia coli was used as a food model system.

Materials and Methods
Test Product
The microchip spiral tube device (N3C) was used in this study.
Sample Preparation and Analyses
Three Escherichia coli cultures from the Silliker Research Culture Collection were used in this study. Cultures were obtained from American Type Culture Collection (ATCC; Atlanta, GA). Each culture was grown in Tryptic Soy Broth (Difco Laboratories, Detroit, MI) at 35°C for 24 hours. Equal numbers of each culture were mixed to make a three-strain Escherichia coli culture cocktail.
