Chemical Composition, Amino Acids, Phenolic Profiles and Bioavailability of Minerals in Livingstone Potato (Plectranthus esculentus) as Affected by Different Processing Techniques

open access: yesFood Chemistry International, Volume 2, Issue 2, Page 186-199, June 2026.
Boiling retained the nutrients and polyphenol compounds in Plectranthus esculentus tubers better than frying or roasting. A bioavailability study showed that the phytates and oxalates in the tuber may not affect the bioavailabilities of calcium, zinc, or iron in Plectranthus esculentus tubers when eaten.
