Nutritional Aspects of Milk Processing

The video challenges the belief that raw milk is nutritionally superior to processed milk. It explains that pasteurization does not significantly alter the mineral content of milk and only slightly affects some proteins and vitamins. The video emphasizes that the benefits of pasteurization, such as eliminating harmful pathogens, outweigh the minor nutrient losses. It also highlights that factors like packaging and storage have a greater impact on nutrient loss than pasteurization itself.

What is the main argument against the belief that raw milk is superior to pasteurized milk?

• Pasteurization does not significantly alter nutrients.

• Raw milk is less nutritious.

• Pasteurization improves taste.

• Raw milk has more bacteria.

How does pasteurization affect the mineral content in milk?

• It adds artificial minerals.

• It significantly reduces mineral content.

• It does not change mineral content.

• It increases mineral content.

What percentage of milk protein is casein?

• 100%

• 80%

• 50%

• 20%

What happens to whey protein during pasteurization?

• All whey protein is denatured.

• A minor portion of whey protein is denatured.

• Whey protein is completely destroyed.

• Whey protein content increases.

Which vitamin is added to milk after pasteurization to prevent malnutrition?

• Vitamin A

• Vitamin C

• Vitamin B12

• Vitamin D

Which vitamin remains stable during pasteurization?

• Vitamin C

• Vitamin B6

• Vitamin B2 (Riboflavin)

• Vitamin B9

What is the main reason for adding vitamins A and D to milk after pasteurization?

• To improve color

• To prevent diseases and malnutrition

• To enhance flavor

• To increase shelf life

Which factor does NOT significantly affect nutrient loss in milk?

• Pasteurization

• Type of packaging

• Light exposure

• Storage temperature

What is a potential risk of consuming raw milk?

• Improved digestion

• Bacterial infection

• Better taste

• Increased nutrient content

Why is pasteurization considered important for milk safety?

• It increases the milk's shelf life.

• It reduces the risk of bacterial infections.

• It eliminates all microorganisms.

• It enhances the flavor of milk.
