5 in foods? This chapter begins by discussing the factors affecting the stability and shelf life of meat and poultry, including microbial loading and factors affecting meat colour, flavour and tenderness.

Produce such as tomatoes, mushrooms, sprouts, and berries are irradiated with the emissions from cobalt-60 or cesium-137. The methods of shelf life analysis will then be reviewed for microbiological shelf life analysis as well as chemical and sensory analysis. This exposure kills a lot of the bacteria that cause spoilage, so the produce stays fresh longer. Before I leave this topic, let me add that tenderness of meat and poultry depend on the age of the animal and the part of animal bought. Eggs Disagreeable colour, flesh that leaves a dent when pressed and dry skin are signs of spoilage.
