What causes food decay?

Answer 1

Bacterial activity.

Any un-preserved or uncooked foods are vulnerable to food decay.

Bacteria find the food, release enzymes on to the food and then digest the enzymes.taking part of the food away.

Remember bacteria need certain living conditions.

• Moisture
• Non acidic or alkali conditions
• Food
• Oxygen

So methods live salting and sugaring can absorb moisture, killing bacteria. Along with freezing.

Pickling can create acidic and alkali conditions, killing bacteria.

Answer 2

It is said that all types of sugar can cause tooth decay. The most expected sugars to give tooth decay are sucrose, glucose, fructose, and maltose. Bacteria use the energy in the sugar and then make acids which attack teeth and tooth enamel. This then causes tooth decay, which is also known as dental caries. Bacteria in also found in dental plaque and that stick to our teeth, also causing tooth decay. The likeliness of getting dental caries and making cavities expand, increases each time we eat sugary foods. Some people get tooth decay worse than others. This is because: Þ The strength on some people tooth enamel is stronger than others. Þ Some people eat less sugary foods than others generally. Þ Some people look after their teeth better than others so are less vulnerable to get tooth decay. If we have a large amount of sugary foods and drinks in our diet, our mouth will be acidic and will take about 20-30 minutes to return to its normal pH level.

Answer 3

Food decay is caused by the growth of bacteria, mold, and other microorganisms that break down the food's components. Factors such as moisture, temperature, and oxygen availability can accelerate the decay process. Additionally, enzymes present in the food can also contribute to its decomposition.

Answer 4

not brushing your teeth and eating too much sweets. tooth decay is very popular throughout the world!!!
