When food becomes spoiled, the original nutritional value, texture, flavor of the food is damaged and is unsuitable to eat. It also may become softer than usual. The changes that occur in food spoilage can be detected by smell, taste, touch, or sight. Food spoilage is caused by a combination of various factors such as light, oxygen, heat, humidity, and microorganisms. The three types of microorganisms are moulds, yeasts and bacteria. There are two types of yeast: true yeast and false yeast. True yeast digests sugar and it turns into alcohol. False yeast grows as a dry film on a food surface. False yeast happens in food that have a lot of sugar or in a high acid environment. Moulds form a tough mass which is visible and can cause you to be sick, …show more content…

When we were born tiny organisms surrounded and came inside your body. These tiny organisms are called bacteria. They are everywhere. Bacteria are prokaryotes. There are two kingdoms of bacteria which are archaebacteria and eubacteria. Archaebacteria already existed on earth billions of years ago before dinosaurs appeared. Some live in salty water and some in our intestines. Eubacteria live on and in your body. There are many types of bacteria that cause spoilage. Bacteria are mostly in vegetables and meat. Enzymes are proteins found in all plants and animals. If uncooked foods are not used while fresh, enzymes cause undesirable changes in colour, texture and flavour. Enzymes are destroyed easily by heat processing. Besides microorganisms, oxidation can affect food spoilage. Oxidation is atmospheric oxygen can react with some food components which may cause rancidity or color changes. Low temperature injury is the internal structures of foods which are damaged by very low temperature. Eating spoiled food caused by bacteria can get you food poisoning. To prevent food spoilage, keep food in refrigerators or inside a container to ensure its good quality. Wrapping food can keep food from spoiling and could save …show more content…

Foil has many purposes besides preventing food spoilage. It can keep the oven clean, get rid of rust, make a funnel, be used for baking, fix loose batteries and much more. Aluminum foil is produced by rolling sheet ingots cast from molten billet aluminum, then re-rolling the sheets to the desired thickness. To maintain a constant thickness, beta radiation is passed through the foil. Sensors on the far side sense the radiation levels and adjust the rollers to apply more or less pressure. Foil can also be produced by continuously casting and cold rolling. Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil is used extensively in food and pharmaceutical packaging. It is also used to make aseptic packaging that enables storage of perishable goods without refrigeration. When a plant, animal, or insect dies, that plant, animal, or insect is broken into tiny pieces and those pieces become part of the soil. This is called decomposition. Bacteria, fungi, and some worms are what break down dead plants, animals, and insects. The bacteria, fungi, and worms are called decomposers. Decomposers need to eat some of the dead things so they can live and grow. The tiny pieces left over after decomposers eat become part of the soil. Living plants take what they need from these pieces so they can grow. The parts of these pieces that living plants take to grow are called nutrients. So, living plants make their own food, but they
