Which enzyme is commonly used to break down pectin in fruit juices?

  1. Pectinase

  2. Amylase

  3. Cellulase

  4. Lipase


Correct Option: A
Explanation:

Pectinase is an enzyme that breaks down pectin, a natural component of fruits that can cause cloudiness and viscosity in fruit juices.

What is the primary role of filtration in fruit juice production?

  1. Removing Microorganisms

  2. Adjusting pH

  3. Enhancing Flavor

  4. Improving Color


Correct Option: A
Explanation:

Filtration is used to remove microorganisms, such as bacteria and yeasts, from fruit juices, ensuring their safety and preventing spoilage.

Which process is commonly used to concentrate fruit juices?

  1. Evaporation

  2. Reverse Osmosis

  3. Ultrafiltration

  4. Freeze Concentration


Correct Option: A
Explanation:

Evaporation is a widely used method for concentrating fruit juices. It involves removing water from the juice under vacuum conditions.

What is the purpose of deaeration in fruit juice production?

  1. Removing Oxygen

  2. Adjusting pH

  3. Enhancing Flavor

  4. Improving Color


Correct Option: A
Explanation:

Deaeration is a process used to remove oxygen from fruit juices, which helps prevent oxidation and spoilage, and maintains the flavor and color of the juice.

Which process is used to preserve fruit juices and extend their shelf life?

  1. Pasteurization

  2. Sterilization

  3. Freezing

  4. Aseptic Packaging


Correct Option: A
Explanation:

Pasteurization is a heat treatment process used to kill harmful microorganisms in fruit juices, ensuring their safety and extending their shelf life.

What is the role of additives in fruit juice production?

  1. Enhancing Flavor

  2. Adjusting pH

  3. Improving Color

  4. Preserving Quality


Correct Option:
Explanation:

Additives are used in fruit juice production to enhance flavor, adjust pH, improve color, and preserve the quality of the juice.

Which factor significantly influences the quality of fruit juices?

  1. Fruit Variety

  2. Harvesting Time
