You are watching: Is food spoiling a chemical change

Factors the can cause food come spoil incorporate microbial, chemical and physical reaction which impact the taste, smell and appearance that a product.


Microorganisms are usual in foods, especially bacteria, yeasts and molds. These microorganisms space all around us and naturally present in some foods. However, if the suitable precautions space not taken, microorganisms feed off the moisture and also can conveniently lead come contamination.

When exposed to unsuitable storage conditions, in between 40 °F and 140 °F, microorganisms can quickly multiply and release danger toxins, even if the food spend is cooked come a for sure temperature. Here are the key culprits:

Clostridium perfringens grows in conditions with tiny or no oxygen and is generally found on raw meat and poultry.Bacillus cereusis the most common cause of food poisoning. This bacterium grow at a range of temperatures and pH and also is found in decaying essential matter.


Chemical alters involving exposure come oxygen and also light space the 2nd most common cause of spoilage. Oxygen can reason food to spoil in several ways:

Encouraging the expansion of microorganisms, leading to mold and also yeast growth.Oxidizing enzymes rate up chemical reactions in food, bring about browning and foul odors.Oxidizing lipids attack fatty portions in food, resulting in foul odors and also an turn off flavor.

It’s inevitable, food will certainly be exposed come light. Whether herbal or artificial, irradiate can cause photodegradation i beg your pardon can reason lead to discoloration, off-flavor and vitamin ns of a product.


Raw develop is particularly prone to physics spoilage as result of bruises and also cracks. Physical damage can also be contributed to wrong packaging, damaged packages and also even dented cans. The damage endured offers an open door because that microorganisms, life creatures and environmental factors.

In terms of temperature, too much heat will rate up enzyme reactions. Cold temperature will reason accidental freezing and also thawing, resulting in cracking. But, a bulk of spoilage takes ar at middle temperatures.


There is no administration system for food spoilage, only control measures you deserve to implement with assist from a HACCP plan. Other than the safe managing of food, it all comes under to appropriately controlling and also maintaining temperatures.

To certain food and also consumer safety, keep food the end of the “Danger Zone” (between 40 °F and 140 °F). The greater the temperature gets; the faster food will certainly deteriorate. Follow to, because that every 18 °F rise in temperature in ~ the temperature range where many food is taken on (50 °F come 100° F), the price of chemistry reaction is about doubled.
