Effect of Some Predominant Storage Fungi on Physico-Chemical Properties of Safflower and Sesame Oil

Role of Fungi on Oil Quality of Stored Seeds of Sesame, Rape and Linseed

“…Rate of reduction was maximum when the seeds were inoculated with A. fumigatus and A. niger indicating thereby that these fungi were more efficient in decreasing oil content than A. funiculosus and A. chevalieri. Bose and Nandi (1982) repprted loss of oil content to depend not only on the fungal species involved but also on the composition of fatty substrate.…”

“…OILSEED LIKE RAPE, black cultivar of sesame and linseed are extensively cultivated and stored in different parts of the world including India, as their oils are used in culinary as well as for industrial purposes. These oilseeds often become invaded by fungi in both natural storage and under controlled conditions (Mondal et al, 1981;Nandi et al, 1982). Different species of these fungi produce varied amounts of lipase (Goodman and Christensen, 1952;Jensen, 1974;Chander et al, 1977) which change considerably the amount and quality of oil (Bose and Nandi, 1982).…”

Consequently, not only is oil from the deteriorated seeds of inferior quality but also the cost for refining the oil rises from a normal l-1.5% to over 5%, resulting in great economic loss to both farmers and the industry.…”
