• Determination of free fatty acids.
• Determination of the saponifiable and unsaponifiable fat fractions.
• Determination of the different types of alkalinity.
• Determination of rosin.
• Determination of phenols and cresols.
• Discuss the restrictions of the CMPs used for application to various types

Seminar 7.3
Solving an Analytical Problem in the Nutritional Domain
The Aflatoxin Content in Cereals and Dried Fruits
• Learning objective
To examine a typical example of major food toxicity problems and be able to
choose an effective analytical approach in order to obtain pertinent, appropriate information.
• Literature
"Official Methods of Analysis" (l5th edn), Vol. 2, AOAC, Arlington, 1990,
pp.1l84-1213.
• Procedure: Issues
• Properties and toxicity of mycotoxins.
• Types and features of atlatoxins. Contaminated foods: types and sources.
• General cautions to be exercised in their analytical determination.
• Preparation of standards.
• General methods for the identification and quantitation of atlatoxins.
Screening methods based on immunoassay.
• Description of the CMPs to be used to identify or determine atlatoxins in
cereals and dried fruits.
• Critical comparison of available CMPs for the determination of atlatoxins
in various types of food matrices.
• Impact of the presence of atlatoxins on various types of food.
Suggested Readings
(1) "The Analytical Problem", M. Valcarcel and A. Rios, Trends Anal. Chern., 16,
1997,385
This paper can be viewed as the "skeleton" for this chapter, which was inspired by it.
(2) "A Holistic Approach to Analytical Chemistry", H. Pardue and H. Woo, J.
Chern. Educ.,61, 1984,409.
This paper provides a broad view of the impact of Analytical Chemistry.
