Proximate analysis and utility indices of some common vegetables of South East Nigeria
Publication Date : 20/12/2019
Analysis of proximate Composition and utility indices of some common vegetables of South East Nigeria was carried on between 2017 and 2018. The aim was to ascertain the core nutritional capacity of our vegetables and their wholistic Economic relevances. Proximate methods after (AOAC, 1984) which included Differential method (Carbohydrates), Soxhlet fat extraction method (fat), sample digestion using concentrated sulphuric acid in the presence of a metallic catalyst (protein) oven drying methods for (moisture content) etcetera were employed. One hundred and fifty questionnaires with reliability and validity established were distributed amongst staff and students of COOU (Uli and Igbariam), NAU (Awka) Oko and Nsugbe at 30 per institution. At the end of the analysis, it was ascertained that Pterocarpus soyaxica (oha) had the highest carbohydrate (68.35) and fat content (11.65); Talinum triangulare (Gbolodi) had the highest ash content (26.75); Gongronema latifolium (utazi) had the highest protein content (8.23); Murraya koenigii (curry) had the highest fibre content while Amaranthus hybridus (Green amaranth) had the highest moisture content (29.15). The woody vegetable species (perennials-like Pterocarpus soyaxica and Pterocarpus santalinoides (nturukpa) had the highest utility indices (+7) as opposed to the herbaceous species (mostly annuals and biennials (+4) that had the greater numerical superiority. A major challenge we have apart from devegetation, is devising a scientific means of preservation of our vegetables so they can be safely available all the year round (all seasons availability).
