EFFECTS OF PATHOGENIC FUNGAL INFECTION ON THE NUTRIENT AND ANTI-NUTRIENT CONSTITUENTS OF POST HARVEST Irvingia gabonensis (OGBONO) SEEDS
Vol 1 No 2 (2021): KnowEx Food and Agriculture
Submitted: Apr 9, 2021
Published: Apr 18, 2021
Effects of pathogenic fungal infection on the nutrient and anti-nutrient constituents of
post-harvest Irvingia gabonensis seeds were evaluated. The fungi pathogens isolated from partially
rotted seeds of I. gabonensis seeds include Rhizopus stolonifer, Aspergillus flavus, Aspergillus niger
and Penicillium italicum. These fungi were used as test fungi to inoculate healthy I. gabonesis seeds
aseptically. The results of the proximate analysis in (%w/w)/100g of seeds inoculated with test fungi
and uninoculated (control) seeds carried out revealed that there was a significant increase (p<0.05) in
Moisture, Ash and Lipid content of seeds inoculated with the test fungi, relative to uninoculated
(control) seeds. While fiber carbohydrate and protein content decreased in fungi inoculated seeds
relative to uninoculated seeds. There was a significant difference (p<0.05) in mineral content
evaluated. Calcium, Phosphorus and Iron increased in seeds inoculated with the test fungi relative to
the uninoculated, while Potassium, Soduim and Magnesium decreased in seeds inoculated with the
test fungi. Anti-nutrient (phytochemical) content; Tannin, Saponin, Total oxalate and Cynogenic
glucoside increased in the fungi inoculated seeds relative to uninoculated seeds. Significant
differences also existed among the test fungi. Apparently, Penicillium italicum induced more
changes in the anti-nutrient (Phytochemical) content measured. Hence higher values were recorded
by Penicillium italicum in Tannim, Saponin, Total oxalate and Cynogenic glucoside,
