| Food Testing: Working With Yeast | ||||||||
 In this concise programme, we look at yeast - its biology, its history, and the necessary conditions for its growth. Varying contents are used in six test tubes to show why only one of them will inflate a balloon and the effect of using dried and compressed yeast in the making of bread rolls is demonstrated. Students are also shown how to write up the result of the tests. | ||||||||
