Abstract

The investigations were carried out to evaluation of the nutritional composition of Curcuma longa (Tumeric), Allum cepa (Onion), unfermented Parkia biglobosa and the combination of the three spices.

            The unfermented seed of Parkia biglobosa were gotten from Forestry Research Institute of Nigeria Ibadan while rhizome of turmeric and onion bulb were gotten from New Market Ijebu, Ogun State. These were identified in the Department of Soil Science, Forestry Research Institute of Nigerian, Ibadan, Nigeria. The turmeric rhizome and onion were peeled and diced, the unfermented Parkia biglobosa with the other recipes were oven dried at 45oC which it was grounded into powder and packaged ready for analysis. Standard Method of the Association of Official Analytical Chemists (AOAC, 2000) were used for proximate analysis and mineral contents determination of each recipe. Parameters investigated for proximate analysis incudes; crude protein, crude fat, crude fiber, total ash, dry matter, nitrogen free extract and mineral contents; calcium, magnesium, iron, sodium, potassium, phosphorus.

            From the result of the proximate analysis, there were significant difference in the crude protein, crude fat and total ash values. However, there was no significant difference between unfermented Parkia biglobosa combined with onion and unfermented Parkia biglobosa combined with turmeric and onion but there was significant difference in other spices in crude fibre, moisture content, dry matter, nitrogen free extract values. Also, from the result of the mineral content, there was significant difference in the potassium and phosphorus values. However there was no significant difference between unfermented Parkia biglobosa combined with onion and unfermented Parkia biglobosa combined with turmeric and onion while other spices were significantly different in the calcium and iron value, there was no significant difference in the turmeric and unfermented Parkia biglobosa combined with onion while other spices were significantly different in magnesium value. There was also no significant different difference in the turmeric and unfermented Parkia biglobosa combined with turmeric and onion while other spices were significantly different in the sodium value.

            It is evident from this study that the recipes were rich in some essential minerals particularly potassium. Also, they were highly nutrition. The study has shown that there was higher nutritional value and mineral content value for recipes when combined together. This shows that combination of different recipes can be added to daily nutritional intake. All the recipes also contained proximate and mineral component which could be of pharmacological importance to animals and humans.
