Abstract Several soybean processing plants were involved in a plant survey to determine (a) material sampled, (b) method of sampling, (c) sample locations, (d) frequency of sampling, (e) variables checked, (f) method of sample evaluation, and (g) instruments used in sample evaluation. Errors in sampling occur more frequently than in sample analysis. It is difficult to obtain a material stream grab sample that is representative of the stream. The only accurate sampling and analytical method would be to sample the entire throughput tonnage of the plant. Since this procedure is not feasible, regular and consistent sampling of product streams must be maintained.
