Hidden hunger, caused by lack of micronutrients in the diet
afflicts billions of people especially in developing nations
with the WHO, estimating 1.4% of all deaths occuring worldwide,
attributed to vitamin A deficiency (VAD). In Kenya, indigenous
vegetables such as Solanum nigrum and Asystasia mysorensis
are rich in beta carotene, but face challenges of being seasonal,
ignored or under utilized. While oils increase bioavailability
and bio accessibility of beta carotene, the retention of the
carotenoid extracted from S. nigrum and A. mysorensis preserved
separately in sunflower and palm oils for a period of 180 days
were investigated. The peroxide and acid values of the oils were
determined and the mean levels of beta carotene extracted
from A.mysorensis are preserved in sunflower and palm oils
reduced by 73.14% and 69.95%, respectively and in S. nigrum
preserved in sunflower and palm oils reduced by 81.56% and
65.56%, respectively. In terms of retinol activity equivalent, the
oils retained enough beta carotene to provide recommended daily
allowance for infants and adults projecting a solution in curbing
VAD. Peroxide values in sunflower and palm oils increased while
acid values increased. These values indicate that oxidation of the
oil matrices occurs with time but not to critical levels of 10 mEq/
kg oil and 0.6 mg KOH/g, respectively. The findings indicate a
significant reduction in levels of beta carotene (p≤0.001) though
amounts remaining are able to meet daily requirements and thus
can be promoted with a particular focus on addressing vitamin A
deficiency.
