Answer 2

more

Question 3

Answer 3

more

Question 4

Answer 4

more

Question 5

See table in notes summary for diff amounts of certain milk factors by species.

Question 6

What is cows milk rich in?

Answer 6

Rich in protein and source of calcium

Question 7

What is the fat % of cows milk?

Answer 7

3 - 4% of the solid content of cow milk

Question 8

What is the protein content of cows milk

Answer 8

3.5%

Question 9

What is the lactose content of cows milk?

Answer 9

5%

Question 10

What breed of attle has the highest milk fat content?

Answer 10

Jersey and Guernsey

Question 11

What is a potential cause of symptoms associated with lactose intolerance?

Answer 11

The A1 protein is being regarded as a potential cause of symptoms associated with lactose intolerance.

Question 12

What is the fat content of buffalo milk?

Answer 12

Very high.
6 - 8%.
fat:protein ratio = 2:1

Question 13

What factor of buffalo milk allows for cheese making?

Answer 13

Buffalo milk also has a higher casein-to-protein ratio than cattle milk.
The high calcium content of casein facilitates cheese making.

Question 14

What is the special factor of camel milk?

Answer 14

-> Similar composition to cow milk but is slightly saltier.
-> Camel milk can be three times as rich in vitamin C as cow milk and represents a vital source of this vitamin for people living in arid and semi-arid areas, who often cannot obtain vitamin C from fruits and vegetables.

Question 15

Why is sheep milk appropriate for making cheese and yoghurt?

Answer 15

The high protein and overall solid contents of sheep milk make it particularly appropriate for cheese and yoghurt making. (feta cheese)

Question 16

Why is it believed that sheep milk is easier to digest?

Answer 16

Goat and sheep’s milk (along with human breast milk) largely contain the A2 protein that many claim is more easily digested.

Question 17

What is goat milk similar to and where is it normally consumed?

Answer 17

-> similar composition to cow milk.
-> In Mediterranean countries and in Latin America: goat milk is generally transformed into cheese
-> in Africa and South Asia: it is usually consumed raw or acidified.

Question 18

Why is goat milk beneficial to humans?

Answer 18

Acts a prebiotic and stimulates growth and division of beneficial probiotic bacteria in gut.
lower levels of lactose = easier to digest.
A2 protein = easier to digest.

Question 19

What type of fatty acid chain is present in goat milk and what is its advantage?

Answer 19

More medium chain fatty acid = quick source of energy and not stored as body fat.

Question 20

Characteristics of yak milk

Answer 20

tastes sweet and has a fragrant, sweetish smell

Question 21

Composition of yak milk

Answer 21

15 and 18 percent solid content.
5.5 to 9 percent fat.
4 to 5.9 percent protein.
It therefore has higher solid, fat and protein contents than cow and goat milk, and resembles buffalo milk.

Question 22

Composition of equine milk

Answer 22

-> horse and donkey ilk is similar.
-> low in proteins (particularly caseins) and ashes.
-> rich in lactose.
-> Compared with that of other dairy species, equine milk contains low levels of fat and protein.
-> consumed fermented.
-> not suitable for cheese making.
