          Abstract

          RESUMEN Se evaluaron las características químicas de un ensilado de raquis de plátano (Musa paradisiaca) y banano orito (Musa acuminata AA) tratado con suero de leche. Se prepararon 24 microsilos de 1 kg de capacidad y se determinó el pH, materia seca (MS), proteína bruta (PB), fibra bruta (FB), cenizas, extracto etéreo (EE), extractos libres de nitrógeno (ELN) y energía bruta (EB) a los 0, 1, 4, 8, 15 y 30 días de conservación (cuatro microsilos por cada día). El material ensilado presentó un adecuado pH y produjo incrementos significativos en el contenido de MS, PB, cenizas, EE, ELN, EB y una reducción en el contenido de FB, respecto al raquis en estado natural. Hubo ausencia de Escherichia coli, Clostridium spp y Salmonella spp. Se evidenció olor ácido suave y fuerte, color marrón claro y oscuro y consistencia sólida y semisólida. El uso de material secante, melaza, urea y suero de leche permitió mejorar la composición nutricional del raquis de plátano y banano, generando un alimento de apreciada calidad nutritiva para su empleo en la alimentación animal.

          ABSTRACT The chemical characteristics of a silage of banana (Musa paradisiaca) and baby banana (Musa acuminata AA) rachis treated with whey and urea were evaluated. In total, 24 microsilos of 1 kg capacity were prepared and the pH, dry matter (DM), crude protein (CP), crude fibre (CF), ashes, ether extract (EE), nitrogen-free extracts (NFE) and gross energy (GE) were determined at 0, 1, 4, 8, 15 and 30 days of conservation (four microsilos for each day). The silage material presented an adequate pH and produced significant increases in the content of DM, CP, ash, EE, NFE and GE and a reduction in the content of CF, with respect to the rachis in its natural state. There was an absence of Escherichia coli, Clostridium spp and Salmonella spp. Mild and strong acid odor, light and dark brown color and solid and semi-solid consistency were evident. The use of drying material, molasses, urea and whey allowed to improve the nutritional composition of plantain and banana rachis, generating a feed of appreciated nutritional quality for use as animal feed.

            Chemical composition and nutritional value of unripe banana flour (Musa acuminata, var. Nanicão).

            Banana flour obtained from unripe banana (Musa acuminata, var. Nanicão) under specific drying conditions was evaluated regarding its chemical composition and nutritional value. Results are expressed in dry weight (dw). The unripe banana flour (UBF) presented a high amount of total dietary fiber (DF) (56.24 g/100 g), which consisted of resistant starch (RS) (48.99 g/100 g), fructans (0.05 g/100 g) and DF without RS or fructans (7.2 g/100 g). The contents of available starch (AS) (27.78 g/100 g) and soluble sugars (1.81 g/100 g) were low. The main phytosterols found were campesterol (4.1 mg/100 g), stigmasterol (2.5 mg/100 g) and β-sitosterol (6.2 mg/100 g). The total polyphenol content was 50.65 mg GAE/100 g. Antioxidant activity, by the FRAP and ORAC methods, was moderated, being 358.67 and 261.00 μmol of Trolox equivalent/100 g, respectively. The content of Zn, Ca and Fe and mineral dialyzability were low. The procedure used to obtain UBF resulted in the recovery of undamaged starch granules and in a low-energy product (597 kJ/100 g).
