This laboratory manual has two purposes. The first purpose is to describe what food science is and what food scientists do. The second purpose is to describe fun laboratory experiments that demonstrate practical applications of food science. Food science is all of the science involved in taking agricultural food products from the farmer’s gate to t...
Purpose
This experiment demonstrates the principles ofbutter making.
Materials
1. 1/3 cup heavy cream 2. measuring cups 3. clean jar with secure, tight-fitting lid 4. salt (1/3 teaspoon or to taste) 5. crackers
Procedure
1. Pour 1/3 cup of heavy cream into a clean jar. Cap the jar. 2. Shake the jar. Take turns shaking; you may need to shake for 15 to 20 minutes. The cream will start looking like cottage cheese (whipped cream). Continue shaking. 3. You will note a separation of solids and liquids. 4. The solid is butter, and the liquidis buttermilk. 5. Pour off the buttermilk. Add salt to the butter for more flavor. Try the butter on crackers.
Purpose
This experiment demonstrates (1) the precipitation of protein (casein) from milk with an acid (vinegar) and (2) the effectiveness of casein as a bonding agent to make casein glue.
Materials
1. measuring cups and spoons 2. 1/4 cup milk 3. 400 milliliter beaker 4. stir bar 5. pH meter 6. thermometer 7. hot plate 8. stir plate 9. 1 teaspoon vinegar 10. cheesecloth 11. weigh boats 12. 1/2 teaspoon household ammonia 13. glass rod 14. wooden craft sticks
Procedure
1. Pour 1/4 cup of milk into a 400 mL beaker. Place stir bar into beaker. 2. Measure the pH of the milk. Place a thermometer in the beaker. 3. Heat the milk to 158˚F on a hot plate. Remove the beaker from the heat. Remove the thermometer. 4. Place the beaker with the warm milk on a stir plate and add 1 teaspoon vinegar. Stir for 2 minutes. Allow the milk to sit for a few minutes. The casein will precipitate into heavy white curds. The remaining liquid is the whey. 5. Measure the pH of the liq...
Purpose
This experiment demonstrates the importance of salt in meat processing.
Materials
1. food preparation gloves 2. food scale that measures in metric units 3. 100 grams raw ground beef, divided equally 4. smallfood processor 5. 20 milliliters water, divided equally 6. 2 grams salt 7. spoons 8. large white paper such as butcher paper 9. paper towels 10. newspapers
Procedure
Wear gloves when working with raw meat. Keep meat away from other food products. Wash hands and work station after completing the experiment. 1. Place 50 g ground beef into a small food processor. 2. Add 10 mL water. Chop the meat for 15 seconds. 3. Remove the meat from the food processor. Form it into a ball. Flatten it like you are making a hamburger patty. 4. Now, put the slightly flattened meat in the palm of your gloved hand (palm up). Turn your hand over (palm down). What happens? Does...
Purpose
This experiment demonstrates (1) the principles of air pressure, (2) how changes in air pressure can affect food products, and (3)the principle behind applying a vacuum in meat processing.
Materials
1. vacuum pump 2. glass jar suitable to be attached to the vacuum pump (The jar should have a rubber stopper with a hole in it to insert a tube. The tube connects to the vacuum pump. You could also use a capped Erlenmeyer flask with a side arm to attach a tube that will connect to the vacuum pump.) 3. marshmallows (different sizes)
Procedure
1. Place a marshmallow insidethe glass jar. 2. Cap the jar. Connect the tube from the rubber stopper to the vacuum pump. 3. Turn on the vacuum pump. What happens? 4. Turn off the vacuum pump. What happens now? 5. Discuss your results. Variations: You can place several marshmallows inside the glass jar or make a marshmallow man. You can also try expanding chicken meat.
Purpose
This experiment demonstrates how appearance influences our perception of how foods taste.
Sports Drink Materials
1. small sampling cups with lids (2 ozsize is ideal) 2. sports drinks (lemon-lime and orange flavors) 3. red food coloring
Procedure
1. Add a few drops of red food coloring to the lemon-lime flavored sports drink. Mix until the color resembles the orange of orange-flavored sports drink. 2. Pour the two orange-colored sports drinks, lemon-lime and orange, into sampling cups. Label each cup using a code to identify eachtype of drink. 3. Give students both samples. 4. Ask students to pinch their noses and taste each sports drink sample. Record the response. 5. Ask students to release their noses and taste each sports drink sa...
Purpose
This experiment demonstrates how your mouth and nose work together to perceive different flavors.
Materials
1. jelly beans of different colors 2. small sampling cups
Procedure
1. Place two jelly beans of the same color in the sampling cup. 2. Ask a student to pinch their nose and taste a jelly bean from the cup. Record the response. 3. Ask the student to release their nose and taste another jelly bean from the same cup. Record the response.
Purpose
This experiment demonstrates (1) the chemistry of candy making and (2) the effect of temperature on the texture of candies.
Materials
1. shallow baking pan (8x8x2 inch) 2. heavy duty aluminum foil 3. oil spray 4. 435 grams (about 21/8cups) sugar 5. 1/2 cup light corn syrup 6. 1/2 cup water 7. 2-quart saucepan or 1,000 mL beaker 8. candy thermometer 9. stove (for saucepan) or hot plate (for beaker) 10. food coloring 11. 1/2 teaspoon oil flavoring 12. spatula
Procedure
1. Line an 8x8x2-inch pan with heavy duty aluminum foil, extending foil over the edges of the pan. Oil the pan lightly. 2. Combine sugar, corn syrup, and water in a 2-quart saucepan or a 1,000 mL beaker. Place a candy thermometer in the pan. The thermometer should not touch the bottom of the pan or beaker. Stir the mixture over high heat until it boils. 3. Reduce heat to medium. Continue cooking over medium heat. Do not stir the mixture while it is cooking. When the syrup reaches 260˚F, add f...
Purpose
This experiment demonstrates (1) what gluten is, (2) its importance in bread making, and (3) its presence in all-purpose flour.
Materials
