Item Banana and Plantain (Musaspp.) Cultivar Preference, Local Processing Techniques and Consumption Patterns in Eastern Democratic Republic of Congo(International Journal of Agriculture Sciences, 2012) Kimiywe, Judith; Ekesa, B.N.; Davey, M.; Dhuique-mayer, C.; BERGH, I. V. D.; Karamura, D.; Blomme, G.This cross-sectional study carried out in North Kivu (NK) and South Kivu (SK) of the Eastern Democratic Republic of Congo aimed to identify the most preferred Musa cultivars, their processing/cooking methods and Musa consumption patterns among rural households. Our results showed that the preferred cooking banana varieties included yellow-pulped AAA-East African Highland bananas [EAHB] ‘Nshikazi’ (SK) and ‘Vulambya’ (NK), which were valued for their cooking qualities, large bunches and suitability for production of banana beer. The preferred plantains were orange-pulped and included ‘Musheba’ (SK) and ‘Musilongo’ (NK) and were preferred for their short maturation period, large bunches and higher market prices. Over 60% of the households examined had consumed EAHB within24hours, whereas <10% had consumed plantains. The most common cooking method was simple boiling of bananas/plantains and main accompaniments include beans and amaranth leaves. Over 69% of surveyed households that had consumed Musa products had con-sumed them boiled. The majority of the households (90%) obtained banana/plantains from their farms, and >55% of households from SK and NK consumed banana products between 2 and 4 times/week. This information will be used to help direct researchers on the Musacultivars that could be further sampled for carotenoid analysis and those found to be rich could be used in the fast-tracking approach to reduce Vitamin A deficiency.

Substantial levels of provitamin A carotenoids (pVACs) in Musa fruit have been reported, but the bioaccessibility of these pVACs remains unknown. In this study, we used an in vitro digestion model to assess the bioaccessibility (i.e. the transfer into micelles) of pVACs from boiled bananas and derived dishes using the Eastern Democratic Republic of Congo as a study context. In particular, the effect of different food ingredients added to boiled bananas on pVAC’s bioaccessibility was studied. The bioaccessibility of all-trans β-carotene ranged from 10% to 32%, depending on the food recipes, and was modified, particularly when pVACs-rich ingredients (palm oil/amaranth) were added. Efficiency of micellarization of all-trans β-carotene was similar to that of all-trans α-carotene and depended on the cultivar (Musilongo, plantain type, 16%; Vulambya, East African cooking type, 28%), while that of the 13-cis isomer was higher (21–33.5%). Taking into account bioaccessibility, the estimated vitamin A activity was significantly different across the different Musa-based dishes tested. Results are discussed in terms of recommendations to help reduce vitamin A deficiency in Musa-dependent African communities.Item Content and Retention of Provitamin A Carotenoids Following Ripening and Local Processing of Four Popular Musa Cultivars from Eastern Democratic Republic of Congo(Canadian Center of Science and Education, 2013) Kimiywe, Judith; Ekesa, B.N.; Den Bergh, I. V.; Blomme, G.; Dhuique-Mayer, C.; Davey, M.Changes in the concentrations and retention levels of total and individual provitamin A carotenoids (pVACs) during ripening and local processing of the four most popular Musa cultivars of Eastern Democratic Republic of Congo were established through HPLC analysis. The predominant pVACs were all trans ?- and ?-carotene, together constituting about 90% of total pVACs content in raw and processed Musa fruit pulp. The proportion of ?- and ?-carotene was not significantly different in the tested East African Highland Bananas (AAA-EAHB) (‘Nshikazi’ and ‘Vulambya’); in the plantains (‘Musilongo’ and ‘Musheba’), proportion of ?-carotene was almost twice that of ?-carotene. An increase in total pVACs was observed during ripening, with highest levels at ripening stage 3 in all four cultivars. Total pVACs values were as high as 1081µg/100gfw in ‘Vulambya’ and 1819µg/100gfw in ‘Musilongo’. Boiling of the AAA-EAHB and AAB-Plantains resulted to retention of between 40-90% and >95% respectively. Plantains deep-fried in fully-refined palm oil and crude red palm oil for 2 minutes did not seem to lose any pVACs, the levels of total pVACs observed after frying were 100% of what was observed when the fruit was raw. Retinol Activity Equivalents (RAE), in boiled products varied between 22.3 and 173 RAEµg/100gfw, whereas deep fried products had >190 RAEµg/100g edible portion. These results show that the tested AAA-EAHBs and the plantains could meet at least 14% and 30 % of Vitamin A recommended dietary intakes respectively. The findings can therefore guide consumer consumption patterns to maximize vitamin A intake for improved health in these regions and also direct researchers in the selection of Musa cultivars to be incorporated within existing farming systems in the fight against vitamin A deficiency (VAD).
