Food Science Lab Equipment: Refractometer, Centrifuge and Freeze Dryer
The instruments food scientists use to test and develop food. A refractometer measures the sugar in juice or jam; a calorimeter, the energy in food; a viscometer, how thick a sauce is; a texture analyzer, how crunchy or chewy. A centrifuge separates cream from milk, a homogenizer breaks up fat droplets, a lyophilizer freeze-dries food, an autoclave sterilizes and an incubator grows microbes for safety tests.
Moisture and water stand for moisture analyzers and water activity meters, which predict how long a food will keep. Refractometer, at 13 letters, is the longest word.
Food Science Lab Equipment Vocabulary: 11 Words to Find
Words run across, up and down, and diagonally; 4 of the 11 read backwards. The longest word is Refractometer, with 13 letters.
- Autoclave: A pressurized steam chamber that sterilizes lab equipment and canned food at temperatures above boiling.
- Calorimeter: An instrument that measures the energy in food by burning a sample and recording the heat released.
- Centrifuge: A machine that spins samples very fast to separate them, like cream from milk.
- Homogenizer: A machine that forces milk through tiny holes to break up the fat so the cream does not rise.
- Incubator: A warm cabinet that grows bacteria or yeast at a steady temperature, for testing or for yogurt.
- Lyophilizer: A freeze dryer, which freezes food and removes the ice as vapor without melting it.
- Moisture: As in moisture analyzer, which measures how much water a food contains.
- Refractometer: An instrument that measures how much sugar is dissolved in a liquid by how it bends light.
- Texture: As in texture analyzer, a machine that measures how firm, crunchy or chewy a food is.
- Viscometer: An instrument that measures how thick a liquid is, like a sauce or syrup.
- Water: As in water activity meter, which measures the free water microbes can use, to predict shelf life.
How to Solve the Food Science Lab Equipment Word Search
Most words are long and run straight up or down: "refractometer" (13 letters) and "calorimeter" run down, "homogenizer" and "lyophilizer" run up, and both of those have a Z. "Texture" has the only X and "water" the only W; they are the two diagonal words.
Food Science Lesson Ideas
- Ask students what each instrument measures and why a food company would need it.
- Use a refractometer, or a simple hydrometer, to compare the sugar in two juices.
- Discuss how freeze-drying, sterilizing and homogenizing make food last longer.
