“Cheese is naturally white. Organic Valley has responded to customer

requests for traditionally coloured Colby and Muenster.”

Organic Valley

“It all began in

Cheddar Gorge

in Somerset.”

Story of

Cheddar Cheese

Cheddar cheese

was first found in

a Cheddar Gorge

cave!!

Cows and Carotenes: Does what

the cow eat affect cheese color?

“The more

Carotene in the

cow’s food (grass), the

more yellow or

yellow-orange the fat

in the milk”

Plants have carotenes to prevent

photo-inhibition!

Orange light

Why does annatto

make cheese look

orange?

“It scatters only the

yellow-orange

wavelengths of

light.”

Light

how does

it influence the color of cheese?

Casein: the most

important protein in milk

Casein micelle

“Casein Reflects all

light and makes the

cheese look white”

At the very least, perhaps you’ll never view cheese the same way again!

An amateur may consider natural

cheese color only yellow and white…

“ However, you can

“see” some of the

chemistry of cheese

when you discern the

variation in natural

cheese color”
