Chemical Analysis of Tacca leontopetaloides Peels

S.T. Ubwa, B.A. Anhwange and J.T. Chia
Tacca leontopetaloides tubers are known to be a staple food of inhabitants of the area under study, however, the peels have been found to be poisonous to livestock and other animals that feed on them. This study therefore, is aimed at investigating the nutrients and antinutritional factors in order to ascertain their composition in the peels. The peels were collected from Utange and Mbachegh wards in Katsina-Ala Local Government Area and Mbaatikyaa ward in Buruku Local Government Area of Benue State, Nigeria and were labeled as sample A, B and C respectively. The moisture, ash, Crude lipids, crude protein and carbohydrates analysis were determined. Anti-nutritional factors like phytate, oxalate, cyanogenic glycosides and saponins were also determined. Results of the analysis indicate the moisture content to be 18.58, 15.40 and 28.38% for samples A, B and C, respectively. Ash content of the peels was found to be 4.13, 9.60 and 5.13% for samples A, B and C, respectively. Lipids content of the samples was found to be 3.80, 2.85 and 1.10% for A, B and C, respectively. The amount of fibre in sample A, B and C was found to be 2.06, 2.07 and 1.10%, respectively while 0.21, 00.07 and 00.18% was obtained as the protein content of the peels, respectively. The result of carbohydrates was found to be 71.20, 69.35 and 62.94 for the three samples, respectively. Results of anti-nutrition indicate the levels of Cyanogenic glycoside to be high (45.00, 43.00 and 44.00 mg kg-1). Saponin content of the peels was found to be 35.00, 31.50 and 34.50 mg kg-1. Phytate in the sample to range between 28.50-29.50 mg kg-1, while Haemogglutinin and oxalate were found to be 20.00-23.00, 16.50, 19.00 and 15.50 mg kg-1 for samples A, B and C, respectively. Tacca leontopetaloides peels though has high content of carbohydrates, it is not suitable for consumption because of the high anti-nutritional factors.

Hello!

I just would like to ask if the fiber in this study refers to the total dietary fiber content of Indian arrowroot? I wish to use this paper as one of my references in my research study.

Thank you and I'm hoping for your prompt response. :)

Yes it is total dietary fiber
