Chemical and elemental analysis of the edible fruit of five Carpobrotus species from South Africa:
Assessment of nutritional value and potential metal toxicity
Neal K Broomhead
University of KwaZulu-Natal, Republic of South Africa
The nutritional value of the edible fruits of five Carpobrotus species was determined for the first time. The fruits were low in
lipids, high in moisture and may contribute adequately towards the Recommended Dietary Allowance (RDA) for proteins,
carbohydrates and essential elements. Concentrations of essential elements were generally in decreasing order of Ca > Mg > Fe
> Mn > Zn, Cu > Cr > Se ~ Ni ~ Co. C. dimidiatus and C. acinaciformis were rich in Cr contributing between 82 - 143% and
62 - 109%, respectively towards its RDA whilst C. delicious was rich in Mn contributing between 122 – 156% towards its RDA.
The fruits did not exhibit metal toxicity except for C. dimidiatus which had Cd and Pb concentrations exceeding maximum
permissible limits. The results show the fruits of Carpobrotus species to be nutritionally rich hence; they may contribute
positively to the diet of all who consume them.
