Food Additives
Substances that become part of a food product intentionally or incidentally during the processing or production of the food
Salt to preserve foods, herbs, spices or vinegar solutions, sugar, and corn syrup are among the most common food additives
Copyright © Notice: The materials are copyrighted © and trademarked ™ as the property of The Curriculum Center for Family and Consumer Sciences, Texas Tech University.Slide5
Common Food Additives
Monosodium glutamate (MSG) – particularly in packaged Asian foods
Artificial sweeteners, such as aspartame, saccharine, and sodium cyclamate
Antioxidants in oily or fatty foods
Benzoic acid in fruit juices
Sulfites in packaged vegetables

Common Food Additives
Nitrates and nitrites in hot dogs and other meat products
Antibiotics given to food producing animals
Lecithin, gelatins, corn starch, waxes, gums, propylene glycol in food stabilizers and emulsifiers
Coloring agents

Functions of Food Additives
Maintain product consistency
Emulsifiers prevent separation of ingredients
Stabilizers and thickeners provide even textures
Anti-caking agents
keep ingredients free flowingImprove or preserve the nutritive valueFoods and beverages are fortified with nutrients that help to make up for inadequacies in individuals’ diets.

Functions of Food Additives
Maintain the wholesomeness of foods
Preservatives reduce spoilage and rancidity
Control the acidity and alkalinity in foods and provide leavening
Specific substances help to change the acid-base balance of foods to obtain a desired taste, color, flavor, or leavening
Copyright © Notice: The materials are copyrighted © and trademarked ™ as the property of The Curriculum Center for Family and Consumer Sciences, Texas Tech University.Slide9
Functions of Food Additives
Provide color and enhance flavor
Dyes and flavorings are cheaper than the “real” thing (i.e. strawberry flavoring instead of crushed strawberries)

Categories of Food Additives
Anti-caking agents
Prevents the lumping or clumping of fine, powdery substances
Chemical preservatives
(synthetic additives)
New chemicals are produced to aide food preservation and nutrition
Emulsifying agents
Help to evenly distribute tiny particles of one liquid into another and improve the consistency, stability, and texture of food products

Categories of Food Additives
Natural
Naturally occurring substances in plants
Separated from the plant source and used in food as a preservative or enhancer
Nutrients and dietary supplements
Enrich or fortify a food product to maintain or improve nutritional value
Ex. – calcium fortified orange juice

Categories of Food Additives
Sequestrants
Chemical food additive that improves the quality and stability of a food product
Combines with polyvalent metal ions, such as copper, iron, and lead (incidental additives from the production or processing of food), and reduces their ability to deteriorate food
Common sequestrants are EDTA, citrates, phosphates, and tartrates

Categories of Food Additives
Stabilizers
Improve consistency or texture, maintain emulsions, and affect mouth feel of food

Intentional and Incidental
Food AdditivesSlide18
Incidental Food
Additives
T
Substances that become part of the food indirectly through the production, processing, packaging, or storage of the food
product.
Some examples include:
insects
or herbicides from
the field when processing grains
pesticides to prevent infestations
hair from unsanitary processing conditions
wax
from products stored in wax coated
packaging
o
thers?
Food producers and processors must check continuously for incidental additives that may be present in the food.

Intentional Food Additives
T
Additives that are purposely added to foods to improve appearance, flavor, texture, nutritive value, or to prevent spoilage

If you wanted to avoid adding chemical preservatives, what strategies could you use to slow down food spoilage
?
Describe one strategy.
How does it slow down spoilage?
What food will you apply the strategy to? Will it affect flavor?
Approximately how long will you be able to keep your food? Slide22

Regulation of
Food Additives
Delaney Clause
No
additive would be considered safe if it were found to produce cancer when ingested by man or animals or if it were found to cause cancer in man or animalsBecause better technology is able to determine higher cancer risk of an additive, an FDA safe additive can now have a one in a million or less cancer risk
