This model experiment was aimed towards determination of the effect of repeated microwaving on migration of volatile substances to food simulating model solutions from packages commonly used in food industry. For this purpose 5 most common plastic packages were selected: white round shaped polypropylene container for ready to eat courses, its polystyrene cover, yellow polypropylene cup of 175 cm3 capacity, white polystyrene cup of 135 cm3 capacity and polystyrene/polyethylene foil; 3% acetic acid, 15% ethanol and rectified olive oil were taken as food simulating solvents. Prior to microwaving, the samples were stored for 10 days in 5°C. Using the GC/MS combined with static head space technique, 26 substances migrating into food simulants were identified after storage and prior to microwave heating. Cumulative exposure time to microwaving ranged from 2 till 30 min.

The purposes of this questionnaire study were to determine: (1) the availability of information about food product, (2) the contribution of label information to the purchase decision, and (3) the claims for the content of label information. The survey was conducted with a national sample of 1000 adults in 1994. The information available on food package was indicated by the respondents to be generally insufficient. The expiration date, price and composition were considered the most important information, and energy value the least important information for the placement on a food package. The food label was not used as an important source of nutritional information. This study shows the necessity of intensive education of the Polish society to more effective use of the label information on food packages.
