1 May 11, 2009 Warm Up: What are food additives? Today Food Additives Notes Begin Food Additives Assignment

2 What are food additives? Food Additive: substance added to food to enhance flavor, color, texture or keep qualities. Substance that becomes part of a food during processing. Intentional additives: are added on purpose to perform specific functions, listed on labels, actual ingredient Incidental additives: have no function in the finished food, become part of a food through some phase of agricultural production, or of processing, packaging or storage. Ex: oil that a food is cooked in

3 Functions Appearance and Taste: Coloring agents, flavorings, flavor enhancers and sweeteners improve taste and appearance Freshness: Preservatives prevent spoilage of fats, help retain natural color and slow spoilage Nutritional Content: Improve the nutritional content value of foods through fortification and enrichment of important vitamins and minerals

4 Functions Continued Processing and Manufacturing: stabilizers, thickeners, Textures and emulsifiers help to make food products that blend, mix, and bake successfully with the body and texture that is desired

5 Types of Additives Anticaking Agents: prevents lumping or caking of finely powdered Antioxidants: Delay or prevent food products from turning rancid or browning Emulsifiers: help to evenly distribute tiny particles of one liquid into another Flavor enhancers: supplement or enhance the original taste or aroma Flavorings: Heighten natural flavor or restore flavors lost in processing

6 More Additives Humectants: cause food product to retain moisture Leavening Agents: affect cooking results, texture and volume of products Maturing and Bleaching Agents;Dough conditioners: accelerate the aging process of the food product as well as improve its baking qualities Nutrients: Enrich or fortify a food product to maintain or improve nutritional content

7 Additives Continued PH control agents: change or maintain the acidity or alkalinity in food or drink products Preservatives: prevent food from spoilage, extend shelf life and protect natural flavor and color, prevent chemical reactions that cause food to deteriorate Stabilizers, thickeners, texturizers: Impart body, improve consistency or texture, stabilize emulsions and affect mouthfeel Sweeteners: make the smell or taste of food more agreeable or pleasurable

8 Assignment You may work alone or with a partner Create an “Intentional Food Additives” Informational Brochure Describe each of the 14 types of food additives For each type give 2 specific food additives used (example: Color: Red Dye No. 5) For each type of food additives show an example of a food product it is used in (Example: Fruit Snacks) As always: Be Creative! Use Color and Pictures
