PROVITAMIN A RETENTION IN BIOFORTFIED CROPS IN AFRICA
Although it is a derivative of Vitamin B5, pathenol is considered a
provitamin of pantothenic acid and alcohol.
Compared to a tomato sauce meal without avocado, the addition of oneavocado (150 g), more than quadrupled (4.6 times) the conversion of
provitamin A to vitamin A.
This means that both melons appear to be comparable sources of dietary
provitamin A for humans, on par with carrots, which are known to be a major source of
provitamin A.
Carrots contain beta-carotene, also known as
provitamin A, not preformed vitamin A.
Poor diets may also contain few fruits and a limited variety of vegetables and, therefore, low amounts of B-carotene (
provitamin A), folic acid, and vitamin C.
Genetically modified organisms (GMOs) are now used in the production of pharmaceutical drugs, gene therapy, and golden rice (containing
provitamin A).
The
provitamin A was calculated according to the new conversion factor (IOM, 2001), in which 12 [micro]g of [beta]-carotene and 24 [micro]g of [alpha]-carotene, [alpha]-cryptoxanthin and [beta]-cryptoxanthin correspond to 1 RAE (retinol activity equivalent).
The micronutrient with
provitamin A activity occurs naturally in carrots.
