Nutritional Evaluation Of Termitomyces Robustus

ABSTRACT

The study was designed to evaluate the nutritional value of Termitomyces robustus

and it was found to contain carbohydrate, fat, and protein, mineral and anti-

nutritional factors. Result of the proximate composition in percentage (%) were as

follows; carbohydrate (54.34±0.15), protein (33.76±0.28), moisture (14.25±0.08),

fibre (6.27±0.12) and fat (3.43±0.01). The mineral composition of the mushroom

in (mg/bOg) were as follows; potassium (2451.80±41.31), phosphorus

(604.03±8.66), magnesium (91.28±1.18), calcium (57.04±1.63), sodium

(35.38±1.60), iron (17.85±1.04), zinc (8.49±0.40), copper (3.35±0.19), manganese

(2.11±0.01) and selenium (0.12±0.00). The amino acid composition in (g/lOOg)

were as follows; glutamate (16.11±1.11), aspartate (9.03±1.03), leucine

(7.13±0.32), tyrosine (6.88±0.00), arginine (6.49±0.18), phenylalanine

(6.12±0.09), senne (5.84±0.33), valine (5.20±0.09), lysine (4.98±0.08), threonine

(4.81±0.19), isoleucine (4.77±0.05), proline (3.88±0.03), alanine (2.69±0.08),

glycine (2.30±0.10), histidine (2.23±0.04), methiomne (1.71±0.11), tryptophan

(1.35±0.10) and cysteine (1.15±0.06). The result of the anti-nutrient component

shows the presence of cyanogemc glycosides (8.89±0.05 mg/kg), tannins

(0.21±0.00%), trypsin inhibitor (8.00±1.00 pug) and oxalate (0.31±0.00%). The

energy content is (382.04 Kcallg). Hence, these nutrient contents revealed that

Term itomyces robustus is a low energy, health food and may also be used as a

protein supplementary diet.
