Types
of Food Additives
Food additives are chemicals that keep food fresh or enhance its color, flavor or texture. Some people are sensitive to food additives, but this is rare. Reactions to food additives include hives or diarrhea, other digestive disorders and respiratory problems such as asthma.

Types
of food that commonly used are:
- Preservative
• Preservatives
stop microbes from multiplying and spoiling the food.
• Anti-caking
agents stop ingredients from becoming lumpy.
- Antioxidants
•Antioxidants
prevent foods from oxidising, or going rancid. Natural ones are
vitamins C, E, A, selenium and beta-carotene. Artificial ones are BHA
and BHT.
- Flavourings
• Flavors
add flavor. There are approximately 1100 to 1400 natural and
synthetic flavorings available.
• Flavor enhancers give foods a more acceptable taste, restore flavor lost in processing.
• Artificial sweeteners increase the sweetness; artificial sweeteners can make foods more palatable
• Flavor enhancers give foods a more acceptable taste, restore flavor lost in processing.
• Artificial sweeteners increase the sweetness; artificial sweeteners can make foods more palatable
• Aroma
Enhancers: An example is yellowish-green liquid diacetyl which is
used in some cottage cheeses to produce an artificial butter aroma.
- Stabilizers
• Stabilizers
maintain uniformity of food dispersion. The more common ones are
modified food starch and vegetable gum.
- Thickness
• Thickeners
enhance texture.
- Dyes or colouring
• Colors
enhance or add color for foods that may lose theirs during
processing. For example, maraschino cherries are dyed red and green.
THE
ENVIRONMENT
Easy! The environment affects food in many ways. For an example, if their is a drought, that affects our food of course, because the plant does not get enough water so the plant dies, resulting in losing our food (the veggie) and if there is too much water drowning the soil and the roots of the plant, as a result the plant dies. The environment in third-world countries that are experiencing phanom right now is all because even though they are TRYING to grow food, their efforts are useless because eventually the plant will wither away from getting too much sunlight and no more water. If you are in places like the United States or maybe Canada, you should be totally thankful you are not in the same position as some other countries right now! So, in conclusion to my answer, the weather severely impacts on our food supply!
