Question

Germinating barley seeds are used in the preparation of

• A. Lactic acid
• B. Wine
• C. Cheese
• D. Beer

Answer 1

The correct option is D

Beer

Germinating barley seeds are used in the preparation of Beer. Yeast (Saccharomyces cerevicea) acts on the sugars of the barley seeds and converts it to ethanol and $C{O}_2$. The $C{O}_2$ is extracted and stored for later use, while the excess yeast is removed. The fermented broth, with a large amount of ethanol in it, is now called green beer. It is allowed to mature and develop a distinct flavor. After maturation, the liquid is filtered, pasteurized and the $C{O}_2$ that was extracted earlier, is pumped back inside in order to give the beer the fizzy taste. Finally, the finished product is bottled and sold for consumption.
