EVALUATION OF THE HYGIENIC CONDITIONS OF PASTA (WHEAT MACARRONI) BY ANALYTICAL MICROSCOPY

Abstract

Samples of wheat macaroni were examinated for sanitary quality. For extration of the light filth the acid hidrolysis method of the Official Methods of Analysis of the Association of Analytical Chemists, was used. The percentage of wheat macaroni samples rejected was 10% due to the number of insect fragments exceeding the tolerance level (225 insect fragments in 225 g of sample). The contamination by rodent hairs was the main additional factor to reject the samples of the wheat macaroni. When this light filth, was considerated, the percentage of samples rejected  increased to 77,5%.
