Exploitation of convenience food in view of a diet diversification for better nutrition.
Social and economic changes as well as technological innovations in recent years, have caused dramatic changes regarding the kind of nutrition supply observed. The provoking question now is, if a recommendable nutrition and diet diversification is possible with the convenience products available on the market at present. Depending on the degree of cooking or preparation the following convenience steps can be differentiated: initial grade--ready-for-kitchen processing--ready-to-cook--ready-to-mix--ready-to-heat--ready-to-eat. Various preservation strategies can be applied to the food products of each step. In order to keep the nutritional and sensory quality of the food product, these necessary preservation methods should, of course, be as gentle as possible. On each convenience-step a large variety of products exists. By separation of preparation from consumption and the therefore necessary preservation methods, these products are available throughout the whole year. Seasonal limitations are less important, which enhances diet diversification. On the other hand, an impoverishment in raw materials occurs due to the existing concentration tendencies in food production and especially in food trade.
