| Résumé : |
Short-term (up to seven days) preservation of cattlehide intented for production of both collagen and leather necessitates the development of new approaches for microbial control. A method utilizing a 4 percent acetic acid wash and a combination of sodium chloride and hydrolyzed starch-polyacrylonitrile graft copolymers ("super slurpers") to regulate water activity (Aw) may offer a feasibile way of maintaining microbiostatic conditions to meet food-grade requirements or produce a quality hide with minimum handling, processing, and storage. This process could be adapted to current industrial practice with few changes in procedures or equipment. Added benefits would be more sanitary working conditions, less pollution problems, and easier handling of hides with extented preservation possibilities at ambient temperatures (25 to 28°C). |
