Interciencia , 2008,
Abstract: four dehydration methods were employed to produce and, then, characterize and compare flours elaborated from commercial unripe plantain (musa paradisiaca l subsp. normalis), variety harton/horn. dehydration of the unripe edible portion of the plantains was completed using tray chamber and double drum dryers, lyophilization (freeze-drying) and microwave oven. the flours obtained were evaluated in their proximate composition, physical characteristics, and rheological and functional properties. the results indicate that the dehydration processes affected significantly (p£0.05) the proximate composition and physical properties of the flours. the rheological and functional properties were different in each of the flours obtained, showing a non newtonian pseudo-plastic fluid behavior. since the plantain fruits are important crops in tropical and subtropical regions, the elaboration of flours with differences in their functional properties from the perishable fruit validates these flours as ingredients for different food elaborations, such as the drum dried flour for of instant or quick cooking food.

African Journal of Biotechnology , 2008,
Abstract: The genetic variability among 6 cultivars of plantain (Musa paradisiaca L.) grown in Jamaica and Nigeria was studied, using arbitrarily primed PCR (AP-PCR) technique. The cultivars included Maiden plantains and Horse plantain grown in Jamaica: Bini, Ayo and Igbiya plantains grown in Nigeria. DNA fragment band positions were obtained with fragment sizes ranging from 0.438 to 1.926 kb. The single distance matrix calculations and the generated dendrogram revealed a clustering together of plantain cultivars across sources of propagation. The analysis showed that the plantain cultivars studied, were split into two clusters, One group consisted of Maiden plantains and Horse plantain from Jamaica and the second contained Bini, Ayo and Igbiya of Nigeria. Cultivars Ayo and Igbiya were closest while Horse and igbiya were one of the farthest apart, in genetic relatedness.

Asian Journal of Plant Sciences , 2006,
Abstract: Floral and fruit tissues of two cultivars of plantain (Musa paradisiaca L.), P100-F (susceptible) and P200-I (resistant to cigar-end rot disease), grown side by side in a field plot in Benin City, Nigeria, were analysed for eight mineral elements-N, P, K, Ca, Mg, Fe, Na and Zn. Calcium, sodium and zinc concentrations were higher in bracts (0.151, 0.265 and 0.490%) and immature peel (0.520, 0.629 and 0.063%) of the P100-F than in samples of the P200-I cultivar (0.077, 0.210 and 0.032%) and (0.482, 0.490 and 0.032%), respectively. Concentrations of P and K were significantly lower in all tissues analysed of the susceptible (P100-F) than the resistant (P200-I) cultivar. The relevance of these results in relation to the management of cigar-end rot disease of plantain is discussed.

African Journal of Biotechnology , 2007,
Abstract: Slices of plantain (unripe and ripe) of 0.5, 1 and 2 mm thickness were fried at 130 ± 5, 150 ± 5 and 170 ± 5°C for 1 to 10 min in refined palm oil. The results obtained showed that -carotene and vitamin C contents decreased significantly with the elevation of the temperature and duration of frying (p<0.05). The decrease is more important when the thickness of the slices is reduced. Water losses and lipids absorption depend also on the temperature, duration of frying, thickness of plantain and the maturation stage of the plantains. Optimum frying conditions were plantain slices thickness of 1 mm, frying temperature of 150°C for 5 to 7 min.

Journal of Diabetes Research , 2013, DOI: 10.1155/2013/160964
Abstract: Aim. To investigate the ameliorating potentials of cocoyam (Colocasia esculenta L.) and unripe plantain (Musa paradisiaca L.) incorporated feeds on the renal and liver growths of diabetic rats, induced with 55 and 65?mg/kg body weight of Streptozotocin. Method. The blood glucose level of the rats was measured with a glucometer, the protein and glucose and specific gravity (SPGR) in the urine samples of the rats were measured using urine assay strips and urinometer respectively. The chemical composition and antioxidant screening of the test feeds were carried out using standard techniques. Results. Administration of the test feeds for 21 days to the diabetic rats of groups 4 and 5, resulted in 58.75% and 38.13% decreases in hyperglycemia and amelioration of their elevated urinary protein, glucose, SPGR, and relative kidney weights. The diabetic rats administered cocoyam incorporated feeds, had 2.71% and 19.52% increases in weight and growth rates, the diabetic rats administered unripe plantain incorporated feeds had 5.12% and 29.52% decreases in weight and growth rates while the diabetic control rats had 28.69%, 29.46%, 248.9% and 250.14% decreases in weights and growth rates. The cocoyam incorporated feeds contained higher antioxidants, minerals and phytochemicals except alkaloids than unripe plantain feed. Conclusion. Cocoyam and unripe plantain could be useful in the management of diabetic nephropathy. 1. Introduction Diabetes is one of the most challenging diseases of the 21st century that affects essential biochemical pathways of the body (carbohydrate, protein, and lipid metabolism) and whose prevalence is rising globally, including the rural Nigerian populations [1, 2]. Due to the inability of the modern therapy to control all the pathophysiological aspects of the disorder as well as the enormous cost it poses on the economy of the developing nations of the world, alternative strategies are urgently needed [3]. The use of medicinal plants in the traditional management of diabetes mellitus could play an important role in the lives of rural people, particularly in remote parts of developing countries which are poorly served with health facilities. During diabetes, the liver has been reported to decrease in weight due to enhanced catabolic processes such as glycogenolysis, lipolysis, and proteolysis, which is the outcome of lack of insulin in the liver cells while the kidney has been reported to increase in weight due to glucose overutilization and subsequent enhancement in glycogen synthesis [4], lipogenesis, and protein synthesis. These changes
Efecto de Sustratos Foliares Sobre la Sigatoka Negra (Mycosphaerella fijiensis Morelet) en Banano (Musa × paradisiacaL.) y Plátano (Musa acuminata Colla) Effect of Foliar Substrates on Black Sigatoka (Mycosphaerella fijiensis Morelet) in Banana (Musa paradisiaca L.) and Plantain (Musa acuminata Colla)  [cached]

Abstract: La Sigatoka Negra, causada por el hongo Mycosphaerella fijiensis Morelet, es la enfermedad foliar más destructora para la producción de los cultivos de banano (Musa × paradisiaca L.) y plátano (Musa acuminata Colla) en el mundo. Actualmente el control de esta enfermedad se centra en la aplicación de fungicidas químicos, a los cuales el patógeno ha desarrollado resistencia, aumentando los costos de control, el impacto negativo sobre el ambiente y la exigencia de los consumidores por una fruta cada vez más libre del uso de plaguicidas. Se ha desarrollado investigación para promover el incremento de poblaciones nativas de bacterias con actividad lítica sobre M. fijiensis a través de sustratos foliares selectivos de esta microbiota. La aplicación de sustratos foliares con base en quitina coloidal, harina de cebada como fuente de glucano, urea y una solución mineral base, dise ados para fomentar poblaciones de bacterias quitinolíticas y glucanolíticas de ocurrencia natural, mostró una reducción entre un 43 y 46% en el número de ciclos de fungicidas convencionales, al ser aplicados en rotación con estos últimos, con relación al sistema convencional basado en la aplicación de fungicidas. The Black Sigatoka caused by the fungus Mycosphaerella fijiensis Morelet, is the most destructive foliar disease in the banana (Musa × paradisiaca L.) and plantain (Musa acuminata Colla) production around the world. Chemical fungicides are the main control tactics; however, fungicide resistance had increased control costs, besides environmental contamination and consumers demands for a fruit free of pesticide residues. The enhancement of populations of native bacteria through selective substrates, with lytic activity on M. fijiensis, looks as a management alternative. Application of two foliar substrates, that had a mineral solution plus urea, barley flour and colloidal chitin known to built-up biocontrol bacteria, allowed to decrease fungicide applications in from 43 to 46%, when sprayed in rotation with conventional fungicides.

Journal of Food Technology , 2013,
Abstract: Resistant starch, beta-glucan and fructo-oligosaccharide are physiologically beneficial carbohydrates which have been associated with the prevention and management of some diet-related diseases. Various plants are therefore being examined as potential sources of non-digestible oligosaccharides. The objective of this study was to quantify these carbohydrates in unripe plantain and to assess the effect of moist heat processes such as autoclaving and parboiling. Unripe plantain was chipped and either parboiled (60 0C or 100 0C) or autoclaved (120 0C or 130 0C) and freeze-dried for 72 hours. Sample material was processed and assayed in duplicate for glucose, fructose, lactose, fructo-oligosaccharide, -glucan and resistant starch content. Glucose content ranged from 0.90 g/100 g to 1.62 g/100 g. Sucrose content ranged from 1.48 g/100 g to 3.87 g/100 g. Lactose content ranged from 0.49 g/100 g to 3.82 g/100 g. Fructo-oligosaccharide levels decreased from 0.67 g/100 g to 0.59 g/100 g with processing, while -glucan content was unchanged. Resistant starch content decreased from 53.6 g/100 g in unprocessed plantain to 3.69 g/100 g in samples autoclaved at 120 oC. While fructo-oligosaccharide and -glucan levels are not greatly influenced by processing conditions, resistant starch and sugar concentrations are susceptible to considerable changes with increasing processing temperature. This is useful in the potential utilization of plantain as a source of resistant starch and possibly fructo-oligosaccharides in functional food applications.

Asian Journal of Plant Sciences , 2007,
Abstract: Mature green plantain fruits were inoculated with conidial suspension of Fusarium verticillioides and exposed to hot air at 38 and 44°C or dipped in hot water only at 50°C for 5 min, 53°C for 3 min, hot water at 50°C with 5 ppm Benlate (Benomyl) and 5 ppm Benlate only. The controls were neither heat treated nor dipped in chemical. Fruits were then stored at 28±2°C for 21 days. Results showed that heat treatment reduced severity of rot on plantain fruits. Prestorage hot air treatment at 38°C for 48 h and 44°C for 72 h resulted into total disease control and compared favourably with Benlate and hot Benlate treatments. Hot water only at the two time-temperature combinations tested also significantly reduced rot severity. In vitro studies also showed that the fungus was significantly inhibited at 44°C but not at 38°C. Heated fruits also had higher peel colour ratings except those dipped in hot water only at 50 and 53°C which remained green and more green than yellow, respectively. Hot benlate treated fruits had the highest colour rating among dipped fruits while hot air treatment at 44°C enhanced colour development more than 38°C.

Abstract: The feasibility of nutrient uptake by Chlorella vulgaris using a cheap carbon source such as plantain peel extract was studied and its biomass utilized for bioethanol production. Unripe plantain peels were obtained, processed, infused for 48 hrs, extracted and cultivated with the Chlorella species for a period of fourteen days. The microalgal carbohydrate content was hydrolyzed with acid and enzyme while the hydrolysate fermented with 10% concentration of Saccharomyces sp. and Aspergillus sp. at 30°C and pH 4.5 using Separate Hydrolysis and Fermentation (SHF) and Separate Hydrolysis and Co-culture Fermentation (SHCF) methods. Results show that maximum cell growth of 1.56 (OD) and biomass concentration of 19 g/l were obtained with 48 hrs infusion. The result indicated that C. vulgaris utilized PPE medium as a sole carbon substrate and stimulated the secretion of biomass. The
