Low-Fat Preparation Techniques

Reducing the consumption of dietary fat may be accomplished by following dietary guides recommending a meal pattern featuring the selection of foods that are lower in fat, especially the saturated type; relying on lower-fat or non-fat cooking methods; and reducing the fat in recipes. Read more »

The fats in a fryer go through stages that influence the quality of the fried product. At the “new” and “break-in” stages, foods absorb too little oil; just the right amount is absorbed at the “fresh” and “optimum” levels that follow; and then too much soaks in at the “degraded” and “runaway” phases. Many professional chefs claim that foods fry best in oil that has been used at least once. Read more »

Temperature Control

It is difficult to detect overheating visually, because fat does not boil, and heated oil is always hotter than it appears. Overheating contributes to the rapid deterioration of fat through polymerization. Any egg yolks used in the coating batter also contribute to the darkening effect on the fat. Read more »

It is important to select a fat with a high smoke point, at least above 420^oF (216^oC). This temperature is above the average range of temperatures used for deep-fat frying. Selecting a fat with a smoke point at or below the frying temperature will cause it to over-heat and decompose into glycerol and its individual fatty acids. The glycerol is further broken down (hydrolyzed) to a steel-blue smoke called acrolein. Acrolein’s sharp, offensive odor warns people of its presence. This smoke is extremely irritating and even harmful to the mucus membranes of the mouth and nasal passages. Read more »

Deep Fat Frying Care

Not every fat is suited for the high temperatures of deep-fat frying. Vegetable oils, except for olive or sesame oil, and hydrogenated shortenings (without additives such as emulsifiers), all of which are 100 percent fat, are the ones most commonly used for this purpose. Read more »
