3Additives
- Additives are defined by the United States Food
and Drug Administration (FDA) as "any substance,
the intended use of which results or may
reasonably be expected to result, directly or
indirectly, in its becoming a component or
otherwise affecting the characteristics of any
food." Also any additive cannot be used until
deemed safe by the FDA. - Basically, food additives are substances added to
food to preserve flavor or improve its taste and
appearance.
4Direct vs Indirect
- Direct additives are those that are intentionally
added to foods for a specific purpose. Indirect
additives are those to which the food is exposed
during processing, packaging, or storing.

7Preservatives
- Preservatives are additives that inhibit the
growth of bacteria, yeasts, and molds in foods.
8Who thought of preservatives?
- 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.
9What they do
- Additives and preservatives are used to maintain
product consistency and quality, improve or
maintain nutritional value, maintain palatability
and wholesomeness, provide leavening(yeast),
control pH, enhance flavor, or provide color.
10New Improved
- 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.

14RED 40
- When red 40 was first approved by the FDA as a
food coloring additive there was some controversy
as to whether or not it caused tumors and cancer.
Those claims have been proven to be false but now
many parents, Doctors and Teachers are becoming
aware of other concerns regarding intake of red
40, especially in young children.
15Kids and RED 40
- Children are most often the ones who have
sensitivity to red 40. Reactions include temper
tantrums, hyperactivity, aggressive behavior,
uncontrollable crying and screaming, kicking,
nervousness, dizziness, inability to concentrate
and sit still among other findings. Physically
you may get frequent headaches or migraines,
upset stomach and feel ill after ingesting this
additive. Often when Red 40 is eliminated from
the child's diet a remarkable change is noticed
immediately.
16Where it is found
- Red 40 is used in many food products including
kool-aid, orange and other flavored sodas,
cheetos and dorito chips, strawberry pop-tarts,
any candy with red coloring to it including
mm's, skittles, many chewing gums, etc. Also
many children's vitamins and pain relievers/cold
medicine have red 40 in the ingredients.
17Classes of Additives
- Antimicrobial agents
- Antioxidants
- Artificial colors
- Artificial flavors and flavor enhancers
- Bleaching agents
- Chelating agents (which are used to prevent
discoloration and flavor changes)? - Nutrient additives
- Thickening and stabilizing agents
18What to look out for
- A simple general rule about additives is to avoid
sodium nitrite, saccharin, caffeine, olestra,
acesulfame K, and artificial coloring. Not only
are they among the most questionable additives,
but they are used primarily in foods of low
nutritional value.
19Bet you didn't know...
- During the late eighteenth century the French
army was suffering from scurvy, malnourishment,
and outright starvation, and the French
government offered a prize of 12,000 francs to
anyone who could discover a way to preserve food
for the troops. Nicholas Appert, a candy maker,
brewer, and baker, reasoned that he should be
able to preserve food in bottles, like wine.
After fourteen years of experimentation, he
finally discovered that if he put food in glass
jars reinforced with wire, sealed them with wax,
and applied heat, the food didn't spoil. Appert
was presented with the 12,000-franc prize by
Napoleon himself. However, the secret of
preserved food soon leaked to the English, who
proceeded to invent the can, and the armies that
faced off at Waterloo were both fortified by
preserved rations.
