Breadfruit (Artocarpus altilis, Parkinson (Fos)) for Food Security and Novel Food Products.

Breadfruit, Artocarpus altilis Parkinson (Fos), is a traditional underutilized gluten-free staple crop with the potential to alleviate hunger and increase food security in the tropics. A traditional Samoan cultivar, Ma’afala, entered commercial production in 2009 and agricultural production parameters needed to be established. We collected data over a 7 year period from 2006 to 2012 on 24 breadfruit cultivars including Ma’afala at the McBryde Garden in Kauai, Hawaii. Breadfruit trees produced an average of 269 fruit per tree per year with an average fruit weight of 1.2 kg for A. altilis cultivars and 289 fruit per tree with 2.0 kg per fruit for the hybrids (A. altilis A. mariannensis). This translates to an average projected yield of 5.23 t/ha for A. altilis and 8.56 t/ha for the hybrids based on the planting density of 50 trees/ha after 7 years. To establish breadfruit nutritional potential, fruit from 49 breadfruit cultivars (41 A. altilis cultivars and 8 hybrids) were examined for protein quality. Amino acid analysis determined that a full spectrum of the essential amino acids were present in all cultivars and breadfruit is especially rich in phenylalanine, leucine, isoleucine and valine. The cultivar “Ma’afala” contained higher total essential amino acid content than other staples including wheat, corn, rice, potato, soybean and yellow pea. Using a model of human digestion, we determined that breadfruit protein is 10-15% more digestible than wheat and had a more positive impact on cell viability in human epithelial colorectal adenocarcinoma (Caco-2) cells. Together, these data indicate that breadfruit has enormous potential for reducing malnutrition and hunger in the tropics and as an ingredient in food products for world markets.
