  3. Escherichia coli

  4. Streptococcus thermophilus


Correct Option: A
Explanation:

Saccharomyces cerevisiae is a yeast commonly used in the fermentation process of beer production, converting sugars into alcohol and carbon dioxide.

What is the primary role of enzymes in the production of cheese?

  1. Breaking down lactose into glucose and galactose

  2. Converting milk proteins into amino acids

  3. Producing lactic acid from lactose

  4. Adding flavor and aroma compounds


Correct Option: A
Explanation:

Enzymes, such as lactase, play a crucial role in breaking down lactose, the sugar present in milk, into glucose and galactose, allowing for the production of cheese.

Which fermentation process is employed in the production of yogurt?

  1. Lactic acid fermentation

  2. Alcoholic fermentation

  3. Acetic acid fermentation

  4. Propionic acid fermentation


Correct Option: A
Explanation:

Yogurt production involves lactic acid fermentation, where bacteria like Lactobacillus bulgaricus and Streptococcus thermophilus convert lactose into lactic acid, resulting in the characteristic tangy flavor and texture of yogurt.

What is the main function of yeast in the production of bread?

  1. Providing nutrients for the growth of bacteria

  2. Converting starch into glucose

  3. Producing carbon dioxide for leavening

  4. Adding flavor and aroma compounds


Correct Option: C
Explanation:

During bread production, yeast consumes sugars present in the dough and produces carbon dioxide as a byproduct, causing the dough to rise and resulting in a light and airy texture.

Which enzyme is commonly used in the industrial production of high-fructose corn syrup?

  1. Glucose isomerase

  2. Amylase

  3. Cellulase

  4. Pectinase


Correct Option: A
Explanation:

Glucose isomerase is an enzyme employed in the conversion of glucose, derived from corn starch, into fructose, resulting in the production of high-fructose corn syrup, a common sweetener used in various food and beverage products.

What is the primary role of microorganisms in the production of vinegar?

  1. Converting ethanol into acetic acid

  2. Breaking down proteins into amino acids

  3. Producing lactic acid from lactose

  4. Adding flavor and aroma compounds


Correct Option: A
Explanation:

In vinegar production, microorganisms, such as Acetobacter aceti, play a crucial role in converting ethanol, present in alcoholic beverages like wine or cider, into acetic acid, resulting in the characteristic sour flavor of vinegar.

Which microorganism is commonly used in the production of soy sauce?

  1. Aspergillus oryzae

  2. Lactobacillus acidophilus

  3. Escherichia coli

  4. Streptococcus thermophilus


Correct Option: A
Explanation:

Aspergillus oryzae, a fungus, is commonly used in the production of soy sauce. It plays a crucial role in the fermentation process, breaking down proteins and carbohydrates present in soybeans and wheat, resulting in the characteristic flavor and aroma of soy sauce.

What is the main function of enzymes in the production of fruit juices?

  1. Breaking down pectin to improve juice clarity

  2. Converting starch into glucose

  3. Producing lactic acid from lactose

  4. Adding flavor and aroma compounds


Correct Option: A
Explanation:

Enzymes, such as pectinases, are used in the production of fruit juices to break down pectin, a natural component of fruits that can cause cloudiness. By breaking down pectin, enzymes help improve the clarity and stability of fruit juices.

Which fermentation process is employed in the production of sauerkraut?

  1. Lactic acid fermentation

  2. Alcoholic fermentation

  3. Acetic acid fermentation

  4. Propionic acid fermentation


Correct Option: A
Explanation:

Sauerkraut production involves lactic acid fermentation, where bacteria like Lactobacillus plantarum convert the sugars present in cabbage into lactic acid, resulting in the characteristic sour flavor and preservation of sauerkraut.

What is the primary role of microorganisms in the production of kombucha?

  1. Converting tea into alcohol

  2. Breaking down proteins into amino acids

  3. Producing lactic acid from lactose

  4. Adding flavor and aroma compounds


Correct Option: A
Explanation:

In kombucha production, microorganisms, such as yeasts and bacteria, work together to convert the sugars present in tea into alcohol, carbon dioxide, and various organic acids, resulting in the characteristic flavor and health benefits of kombucha.

Which enzyme is commonly used in the industrial production of ethanol from corn?

  1. Amylase

  2. Glucose isomerase

  3. Cellulase

  4. Pectinase


Correct Option: A
Explanation:

Amylase is an enzyme employed in the industrial production of ethanol from corn. It breaks down the starch present in corn into glucose, which is then fermented by yeast to produce ethanol.

What is the primary role of microorganisms in the production of tempeh?

  1. Converting soybeans into a fermented food product

  2. Breaking down proteins into amino acids

  3. Producing lactic acid from lactose

  4. Adding flavor and aroma compounds


Correct Option: A
Explanation:

In tempeh production, microorganisms, such as Rhizopus oligosporus, play a crucial role in fermenting soybeans, resulting in the development of a compact, protein-rich food product with a unique flavor and texture.

Which fermentation process is employed in the production of wine?

  1. Lactic acid fermentation

  2. Alcoholic fermentation

  3. Acetic acid fermentation

  4. Propionic acid fermentation


Correct Option: B
Explanation:

Wine production involves alcoholic fermentation, where yeast converts the sugars present in grapes into alcohol and carbon dioxide, resulting in the characteristic flavor and alcoholic content of wine.

What is the main function of enzymes in the production of beer?

  1. Breaking down starch into glucose

  2. Converting glucose into ethanol

  3. Producing carbon dioxide for carbonation

  4. Adding flavor and aroma compounds


Correct Option: B
Explanation:

Enzymes, such as glucoamylase and maltase, play a crucial role in the production of beer by converting the starch present in barley into glucose, which is then fermented by yeast to produce ethanol, the alcohol component of beer.

Which microorganism is commonly used in the production of miso?

  1. Aspergillus oryzae
