Abstract

Quality assessment of Auricularia auricula-judae was carried out in the Department of Plant Science and Biotechnology, Rivers State. Nutrient and anti-nutrient quality were evaluated and Proximate composition analysis revealed highest (34.225 ± 0.005%) and lowest (0.2 ± 0.00%) content for moisture and fibre respectively. Mineral investigation showed phosphorous to be the highest mineral element (430 ± 0.00mg/100g) while iron recorded lowest value (0.3 ± 0.00mg/100g). Thiamine was the only vitamin seen and it recorded 0.66 ± 0.05. A total of eight anti-nutrients (glycoside, oxalate, saponin, tannin, carotenoid, polyphenol, flavonoid and lignans) were found. Highest anti-nutrient value (3.85±0.05%) was recorded for polyphenol whereas tannin recorded lowest value (0.005 ± 0.0005%). Generally, A. judae has appreciable nutrients and anti-nutrients and its consumption, cultivation and utilization should be encouraged.
