Extension of Poultry Shelf-Life by Poly (Hexamethylenebiguanide Hydrochloride)

Abstract:
Immersion of freshly processed poultry carcasses in solutions of poly (hexamethylenebiguanide hydrochloride), PHMB, retarded bacterial growth and markedly improved the shelf-life during storage at 2 C. Birds treated with 200, 300, and 400 ppm PHMB had average shelf-lives of 22.9, 25.9, and 26.0 days, respectively, compared to the 10.5 days of shelf-life for water-treated controls. Duncan's multiple range test revealed that the shelf-life differences among PHMB-treated birds were not statistically significant.

Metabolism
The basic function of an organism is to consume energy and molecules in foods, convert some of it into fuel for movement, sustain body functions, and build and maintain body structures. There are two types of reactions that accomplish this: anabolism and catabolism.
Anabolism is the process whereby...
