Abstract: A biopolymer film is provided that comprises a combination of crystalline nano cellulose (CNC)/esterified crystalline nano cellulose (ECNC) reinforced with chitosan. The two polymer components can be present in any ratio, but an approximate CNC to ECNC 70:30 ratio is preferred. The chitosan component is derived from exoskeletons of crustaceans. Also provided are methods of preparing biopolymer film and preparing food packaging components from said biopolymer film. The CNC/ECNC mixture is dissolved in an ethanol solution and the chitin is dissolved in acetic acid and mixed together to form a polymer blend.

Abstract: Disclosed are novel genetic arrays for use in the molecular detection of multiple Salmonella serovars, common food-borne and water-borne pathogens. The arrays may be used to simultaneously detect multiple food safety Salmonella serovars. The multiplex-detection methods have improved sensitivity and specificity for the detection of multiple high-impact food-borne pathogens simultaneously. Real-time PCR assaying techniques using such serovars include microarrays.
