Answer (Detailed Solution Below)

Detailed Solution

The correct answer is Caseins.

Key Points

• The white color of milk is due to the presence of caseins.
• Caseins are one of the main types of protein in milk which cluster together with calcium and phosphate to form tiny particles called micelles.
• When light hits these casein micelles it causes the light to refract and scatter resulting in milk appearing white.
• Milk is a natural, whole-food made up of water, protein, fat, carbohydrates in the form of lactose, vitamins including calcium, minerals including phosphorous, and a range of other bioactive compounds.

Additional Information

• Lactose is a sugar found only in milk and dairy products.
  • In our bodies, the enzyme lactase breaks it down into two smaller sugars, galactose, and glucose.
• Albumin is a protein made by your liver.
  • Albumin helps keep fluid in your bloodstream so it doesn't leak into other tissues.
  • It also carries various substances throughout your body, including hormones, vitamins, and enzymes.
  • Low albumin levels can indicate a problem with your liver or kidneys.
• Carotenoids are plant pigments responsible for bright red, yellow, and orange hues in many fruits and vegetables.
  • These pigments play an important role in plant health.
  • Carotenoids are a class of phytonutrients ("plant chemicals") and are found in the cells of a wide variety of plants, algae, and bacteria. They help plants absorb light energy for use in photosynthesis.
  • Carotenoids also act as antioxidants in the human body. They have strong cancer-fighting properties, according to the Physicians Committee for Responsible Medicine.

• Fats and water don’t usually mix, but in milk, the fat and water form an emulsion.
