LOSS OF NUTRIENTS DEMONSTRATION |
CARROT TEST
Grate a carrot into a glass of water and stir.
Point out how the water turns orange. These are nutrients and Beta-carotene 3 (a major antioxidant)
that have leached into the water.
Mention that this can occur when vegetables are boiled, while with the Rena Ware “water-less” cooking
method more nutrients remain in the food.
3 Beta-carotene (β-carotene) is also known as provitamin A, because it is one of the most important precursors of vitamin A in the human diet. Source:School
