Types of Food Spoilage

Microbial Spoilage

-Bacteria are single-celled microorganisms that serve many different purposes-Spoilage in food due to bacteria is because bacteria produce changes in food products as they live and grow-These changes will cause damaged flavour, texture and composition in the food-Certain bacteria can cause milk to turn sour, meat to spoil as well as for wine to turn into vinegar

Bacterial Spoilage

-Mould forms microscopic strands that can extend into food-These can cause allergic reactions or illnesses when one eats the food-Causes the discolouration, change in flavour, odour and the decrease in the consistency of the food-Grow in filament causing a visible, tough mass-Form spores that will float to find suitable conditions in order to start the growth again

Mould Spoilage

-Can cause discolouration, slime and odours on acidic food that is refrigerated as well as jam and jellies-Growth of yeasts causes fermentation-Alcohol and carbon dioxide gas is produced by true yeasts by sugar metabolism-False yeasts can grow a dry film on the surface of food with high sugar or highly acidic environment

Yeast spoilage

-Commonly known as self-digestion-Destruction of a cell through the actions of its own enzymes-Digestion of an enzyme by another molecule of the same enzyme


-Proteins are found in all plants and animals-Causes discolouration, change in texture and flavour in uncooked food that are not used while fresh


-Atmospheric oxygen reacts with some food components-Causes rancidity or discolouration in food
