The Effect of chitosan on microbial, chemical and sensory traitsof minced meat
Résumé
Chitosan is a naturally obtained biopolymer and has many applications in the food industry. The effect of chitosan (1% and 3%) added individually to meat on microbiological profile represented by aerobic plate count (APC), Psychrotrophic, mold and yeast counts; chemical (pH, TVB-N & TBA) and sensory traits (color, odor, appearance and consistency) was studied. Thus, the minced meat samples were divided into 3 groups. The first group was prepared as control (Untreated group) and the other two groups were treated with chitosan at ratio of 1% and 3%. The results indicated that chitosan either 1% or 3% had great destructive effect in all tested microbial groups as compared with control group. From chemical point of view, such concentrations of chitosan improved the chemical quality indices of minced meat. Organoleptically, the control samples were decomposed after the 4th day, while the using of chitosan particularly at 3% extended the shelf life of the experimented minced meat till the 9th day. Finally, it can be concluded that chitosan had great effect on the quality and prolong the shelf life of minced meat as it improves the microbiological and chemical as well as sensory characteristics of minced meat
