In this study, we used the reliable GC-FID/MS technique to analyze the methyl ester derivatives of 37 different kinds of fatty acids. The results showed that high saturated fat concentration in all samples was mostly palmitic acid, whereas the low unsaturated fatty acid content in the cis form was primarily oleic acid and linoleic acid. The amount of monounsaturated and polyunsaturated fats is quite low.

The applications in this book are limited to the analysis of samples of fixed size. Applications to more general stochastic processes, including sequential analysis, will make a natural sequel, but are outside the scope of this book. In some measure this book is a product of questions asked by students and the need for a presentation avoiding special approaches for problems that are essentially related. It is my hope that the experienced statistician will see in this book familiar things in a unified, ifun- familiar, way, and that the student will find this approach instructive.

Mycotoxins are toxic food pollutants that are created naturally by some fungus. By contaminating food, they have a harmful impact on human health. This study's major objective was to simulate food products from bakeries being contaminated. Separate bakery food samples were examined to see whether fungus and associated mycotoxins were present.
