ble bonds are entirely eliminated andthe resulting product is a hard brittlesolid at room temperature. Hydrogeneration conditions can be varied bythe manufacturer to meet physical andchemical characteristics desired in thefood product. Many fats are processedand/or consumed as emulsions, that is,dispersions of immiscible liquids suchas water and oil, e.g., milk, mayonnaise, ice cream, icings and sausage.
Shortenings, margarines, butter,salad and cooking oils, mayonnaise,salad dressing, French dressing, Italianand other specialty salad dressings, andconfectioners' coatings are some of thewidely available products based entirelyon fats and oils, or which contain fat oroil as a principal ingredient (see Table3 for the fatty acid composition of typical margarines). Many of these productsalso are sold as specialized formulationsto food processors, snack food manufacturers, bakeries, restaurants andinstitutions.

Dietary fats have been categorizedinto what are termed "visible" and"invisible" sources of fat. Visible fatsare defined for statistical reporting purposes as those that have been isolatedfrom animal tissues, oilseeds or vegetable sources and are used in suchproducts as shortenings, margarine andsalad oil. Invisible fats are those thathave not been isolated from the animaltissues, oilseeds or vegetable sources,and are consumed as part of animal tissues or vegetables in the diet. In theCanadian diet, meat fats are a majorsource of saturated and unsaturateddietary fatty acids.

University of Ottawa Food and Nutrition Program
The Food and Nutrition Program inthe Department of Biochemistry,University of Ottawa was initiated in1978 to conduct undergraduate andpostgraduate teaching as well asresearch in food science and nutrition.Based in the School of Medicine as wellas the Science and Engineering Faculty,the Program approaches agricultural,industrial and clinical problems at abasic molecular level. For example, various laboratories are currently studyinglipids, proteins, carbohydrates, hormones, and metabolic disorders.
A number of specialized techniques,instruments and laboratory facilities areavailable for collaborative purposes, asis shown by the number of outsideresearch contracts in progress. If youhave any queries please address themto the Chairman, address below.
Food and nutrition courses in the program allow undergraduates to pursueB.Sc. degree options leading to careersor further training in food biochemistry, nutrition or professional dietetics.
Our commitment to the agri-food sector has recently been strengthened bya new position for an additional foodchemistry professor. We are thereforeseeking an individual with postdoctoralresearch experience in any fundamental aspect of food chemistry, be it infood enzymology, pharmacology, toxicology, immunology, carcinogenicity,biodeterioration or in any molecularphenomena occurring during foodstorage or processing. Interestedindividuals should correspond with theChairman of the Department: Dr.Morris Kates, Biochemistry Department, University of Ottawa, 40Somerset St. East, Ottawa, OntarioKIN 9B4.
