T Materials and Methods: 2 oil-extraction plans in Tehran province were chosen as samples. £ Questionnaires were provided concerned with operations, processings and estimated amount / of losses and wastes in different phases of operations. MINITAB software was applied for 8 variance analysis computation in order to compare and estimate the amount of losses and 9 wasted in different phases of oil seed extraction operation. p Results: The study and search indicated average losses of 5-6%, 4-5% and 3-4% for J sunflower, and canola and soybean oils respectively during extraction operation. ^ Conclusion: The financial losses might be regarded considerable and significant in respect of the amount of seed processed annually and the amount of oil extracted and received and the quantity lost.
