what are food additives
What are food additives
  • Food additives are substances added to food to preserve flavor or enhance its taste and appearance.
  • Some additives have been used for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as in some wines.
  • With the advent of processed foods in the second half of the 20th century, many more additives have been introduced, of both natural and artificial origin.

common food additives
Common food additives
  • Artificial Colorings
  • Artificial Sweeteners
  • BHA and BHT
  • Calcium and Propionate
  • Citric Acid
  • Nutrition Ingredients
artificial colorings
Artificial Colorings
  • The colors of food make them more (or less) attractive so manufacturers add colorings to many processed foods. Some food colorings come from natural plant extracts and dyes, but some are created artificially.
artificial sweeteners
Artificial Sweeteners
  • Non-nutritive sweeteners add flavor, but no calories to foods and beverages. That\'s because they\'re 100s of times sweeter than regular sugar or high fructose corn syrup so very little is used.

BHA and BHT
  • Many of the processed foods you buy contain at least a small amount of fat. Butylatedhydroxyanisole (BHA) and butylatedhydroxytoluene (BHT) protect fats from going rancid so you\'ll find them in a variety of processed foods.
citric acid
Citric Acid
  • You\'ll usually find citric acid in foods that contain fruit or fruit flavorings because it adds a tangy sour flavor and is also used as a preservative. Citric acid occurs naturally in many foods, especially in citrus fruits.

Why do foods contain so many additives?
  • Additives are ingredients used in the preparation of processed foods. Some of these are extracted from naturally occurring materials, others are manufactured by the chemical industry.
  • But like every other component of food, all additives are chemicals. Preservatives, colours and flavours are the best known additives but antioxidants, emulsifiers, stabilisers, gelling agents, thickeners and sweeteners are also commonly used.

  • Although there are preservations approved by FDA (Food and Drug Administration ), these preservations have been known to induce allergic reactions.

  • -monosodium glutamate (MSG), which can cause headaches, nausea, weakness, difficulty breathing, drowsiness, rapid heartbeat, and chest pain, must be identified on food labels because of its potential for harm.
  • Recent research also points to health risks from eating nitrites, common preservatives used in cured meats such as sausages, bacon and hot dogs. For example, a 2006 study found that people who regularly eat cured meats have a 71 percent greater chance of contracting lung disease than those who never eat cured meats.

  • There are also many cases in which approved additives once thought to be safe were later restricted or banned after being proven harmful to human health.
  • The artificial sweetener cyclamate, widely used in the 1950s and 1960s, was banned by the FDA in 1970 after research suggested that it caused cancer.
  • The color additive Violet No. 1 was used by the USDA to stamp inspection grades on beef until it, too, was suspected of being a carcinogen and banned by the FDA.
  • After years of use, a flavoring called Safrole that was used in root beer, as well as the common preservative BHA, were both found to cause cancer.21
