Chemical Composition of Musa sepientum (Banana) Peels.

ABSTRACT

Musa sapientum peels were analysed for minerals, nutritional and anti - nutritional contents. The result of mineral content indicate the concentrations (mg/g) of potassium, calcium, sodium, iron, manganese, bromine, rubidium, strontium, zirconium and niobium to be 78.10, 19.20, 24.30, 0.61, 76.20, 0.04, 0.21, 0.03, 0.02 and 0.02 respectively. The percentage concentrations of protein, crude lipid, carbohydrate and crude fibre were 0.90, 1.70, 59.00 and 31.70 respectively. The results indicate that if the peels are properly exploited and process, they could be a high-quality and cheap source of carbohydrates and minerals for livestock.

    ABSTRACT: Banana is eaten all over the world by all sections of the population. It is known to contain potassium and it has been suggested that it could serve as a source of potassium. Recently, a valuable chemical component, a lectin, called BanLec, was isolated from banana fruit and found to possess anti-HIV-1 activity. However, the peels of banana are thrown away as rubbish and farmers are known to use them as feed for their animals. It is therefore necessary to determine the potassium content of some Nigerian bananas and to also extract the oils from their peels. The components of the extracted oils are to be determined and tested for their biological activity. The potassium content of five (5) varieties of Nigerian bananas (Dwarf Cavendish AAA GP; Lady Finger AA GP; Dwarf Chinese Double; Double Dwarf Senorata AA GP; Giant Cavendish (Williams) AAA GP and Dwarf Red AAA GP) was determined using flame photometer. The potassium content varied from 0.15 mg/g (Dwarf Red) to 1.80 mg/g (Lady Finger). Compared to the value of 358 mg per 100 g reported in the literature, these values are very low and considerable lower than the RDA of 4700 mg. The conclusion is that Nigerian bananas will not be a viable source of potassium for candidates with potassium deficiency. A report on the methanolic extract of oil from their peels is given. Two (2) of the five (5) varieties were chosen and methanolic extraction of oils from their peels was undertaken. The crude extract was subjected to phytochemical analysis, which revealed the presence of the following of steroids, saponin and terpenoids, anthraquinones and tannins. A report is also given on antimicrobial studies of the methanolic extracts, which revealed that the oils were effective against some bacteria.

    ABSTRACT: Filamentous fungi are considered to be the most important group of microorganisms for the production of plant cell wall degrading enzymes (CWDE), in solid state fermentations. In this study, two fungal strains Aspergillus niger MS23 and Aspergillus terreus MS105 were screened for plant CWDE such as amylase, pectinase, xylanase and cellulases (-glucosidase, endoglucanase and filterpaperase) using a novel substrate, Banana Peels (BP) for SSF process. This is the first study, to the best of our knowledge, to use BP as SSF substrate for plant CWDE production by co-culture of fungal strains. The titers of pectinase were significantly improved in co-culture compared to mono-culture. Furthermore, the enzyme preparations obtained from monoculture and co-culture were used to study the hydrolysis of BP along with some crude and purified substrates. It was observed that the enzymatic hydrolysis of different crude and purified substrates accomplished after 26 h of incubation, where pectin was maximally hydrolyzed by the enzyme preparations of mono and co-culture. Along with purified substrates, crude materials were also proved to be efficiently degraded by the cocktail of the CWDE. These results demonstrated that banana peels may be a potential substrate in solid-state fermentation for the production of plant cell wall degrading enzymes to be used for improving various biotechnological and industrial processes.
