Understanding Milk Pasteurization: A Sustainable Dairyman's Approach

The video tutorial explains different pasteurization methods, including VAT, HTST, and ultra pasteurization. VAT pasteurization uses low heat to destroy bacteria but offers limited shelf life. HTST and ultra pasteurization use higher temperatures to extend shelf life. The evolution of these methods has led to longer-lasting milk products.

What is the minimum temperature required for VAT pasteurization?

• 120°F

• 145°F

• 200°F

• 160°F

Which pasteurization method is known for using high temperature for a short time?

• Batch pasteurization

• Cold pasteurization

• HTST pasteurization

• VAT pasteurization

What is the approximate temperature used in ultra pasteurization?

• 145°F

• 160°F

• 180°F

• Over 200°F

Why does VAT pasteurization not significantly extend the shelf life of milk?

• It is too time-consuming

• It is not effective against bacteria

• It uses too low a temperature

• It retains some enzyme activity

What advancement in pasteurization allows for a two-month shelf life?

• Traditional VAT pasteurization

• Ultra high temperature system

• HTST pasteurization

• Cold pasteurization
