Preface

To assess and improve the nutritional status of the population, data about the energy and nutrient content of composite foods are necessary because a large proportion of the food consumed is cooked or prepared. As the majority of nutrient databases provide information mainly on the nutrient composition of raw foods, continued efforts have been made by several countries all over the world to update and harmonise the food composition databases and to include the nutrient composition of cooked and prepared foods [3].

The chemical analysis of cooked foods (dishes) involves high costs in terms of time and money and cannot be applied in practical situations e.g. epidemiological studies, institutional kitchens, private households. As it is virtually impossible to analyse every dish item and other prepared foods, calculation of the nutrient composition is still the method of choice.

Experimental results have shown that between the analytical and calculated content of nutrients in prepared foods maximum correspondence is achieved when calculations are based on the following data [1, 2, 3]: a) Data of nutrient content per 100 g edible portion of raw ingredients [4]. b) Quantity of ingredients for preparation of 100 g edible portion of cooked food

(dish) in the ready-to-serve condition. c) Retention factors of food constituents during cooking.

Cookbook recipes usually fail to provide information about the quantities of food obtained after preparation. Therefore weight have to be measured or borrowed from the pertinent literature. In part 1 of this study the algorithm used for determination of weight yield are described and tables of weight yield factors due to different cooking methods for about 700 foods and dishes are presented. The weight yield factors in the tables are based on data in the pertinent literature and on analytical results from our own studies [5-8, 10-11]. They can be used to help estimate weight yield after cooking similar foods and dishes.

In part 2 of this paper the formulae used for calculation and the tables of average retention factors of food constituents after cooking of about 39 typical food (dish) categories are contained. The actual retention factors for protein, fat, carbohydrates, vitamins, minerals, cooking salt, sodium, potassium, magnesium, calcium, phosphorus and iron are statistically approved values. For some other food constituents, in particular niacin, biotin, folate, pantothenic acid, vitamin E , K and B12, fatty acids, amino acids, cholesterol the retention data available are incomplete and should be regarded as estimated retention values. For any other food constituents, for which at present no data are available, using a retention factor of 1.0 is preliminarily recommended.
