Question 1

Deionized water is basically purified water without __________.

A) color
B) minerals
C) carbonation
D) steam

Answer 1

Mineral ions act as electrically charged atoms. In the deionization the ions have been removed from the water as a impurity. So, deionized water is purified water without minerals.
Hence, correct option is .
Deionized water is clear and opaque in appearance. It does not have any colo r. Hence, the option (a) is not correct answer.
Carbonation is related to generating deionized water with desired concentration of carbon dioxide. Carbon dioxide is a gas not a mineral. Hence, the option (c) carbonation is not correct answer.
Steam is a converted form of water forming white minute water droplets in the air during heat. Hence, option (d) steam is not correct answer.

Question 2

Describe how the following types of water differ: mineral, deionized, distilled, and sparkling.

Answer 2

Mineral water has a strong taste or odor due to small amounts of salts of calcium, magnesium, and sodium (sodium bicarbonate, sodium carbonate, sodium chloride), and sometimes iron or hydrogen sulfide.
Deionized water is purified water which does not have minerals content. Deionization removed the ions from the water and make it deionized water. In deionized water both anion and cation removes through a chemical process which is called ion exchange.
Distilled water is purified water. In distillation minerals, pathogens, and other substances removes. Distilled water mainly used for reagent preparation in laboratory. It is also useful for washing glassware because of lack of minerals and ions.
Sparkling water has carbon dioxide which h contributes to bubble or fizz formation. It is mainly present in soda water, soft drinks and some energy drinks and helpful to enhance digestion.

Question 3

The fizz or bubbles in sparkling water are attributed to which chemical compound?

A) Oxygen bromide
B) Carbon carbonate
C) Carbon dioxide
D) Sodium

Answer 3

The fizz or bubbles in sparkling water are attributed to presence of carbon dioxide in water. It is a dissolved form of carbon dioxide gas in water under pressure and this process is known as carbonation of water.
Hence, the correct option is .
Oxygen bromide is a mixture of bromine and oxygen which is formed when electric current pass from the mixture of bromine and oxygen. Hence, option (a) oxygen bromide is not correct option because it has no role in formation of bubbles in sparkling water.
Fizzy water is formed due to presence of some gas in water. Carbon carbonate is a mineral. Hence, option (b) carbon carbonate is not correct answer.
Galactose is a polysaccharide which is form with the glucose and lactose. Hence, the option (d) galactose is not correct answer.

Question 4

Describe the general ingredients in soft drinks and their functions.

Question 5

What factor determines whether a coffee is classified as a light, medium, or dark roast?

A) Grinding level

Question 7

What chemical compounds found in green tea act as antioxidants and may have anticarcinogenic properties?

A) Phenolic compounds
B) Phospholipids
C) Pyrroles
D) Phosphates

Question 8

What is the purpose of roasting, and how does it affect the quality of coffee?

Question 9

What is the principal grain used in beer production?

A) Wheat
B) Hops
C) Malt
D) Barley

Question 10

After roasting, the coffee beans are ground. Why are coffee beans ground, and how does the size of the bean influence the type of equipment that will be used?

Question 11

The substance(s) _____________is/are added to some nutraceutical beverages for joint health.

A) glucosamine and chondroitin sulfate
B) omega-3 fatty acids
C) chromium
D) mangotseen juice

Question 12

What compounds are responsible for the bitter, slightly sour taste of coffee? What preparation mistake causes a higher concentration of these compounds to be processed?

Question 13

Sulfites are often added to red wines to maintain their __________.

A) flavour
B) yeast fermentation
C) color
D) alcohol content

Question 14

Describe the differences among the following types of coffee beverages: espresso, caffe mocha, caffe latte, and café au lait.

Question 15

How should roasted coffee beans be stored so that their freshness is maintained?

Question 16

Explain the differences among black, green, and oolong teas.
