Protein tierischer Herkunft: Gibt es Alternativen?

Considering limited natural resources, such as land, water, some minerals and increased emissions as well as rapid population growth, food security is one of the largest challenges of the current century. Apart from sufficient food, the supply with essential nutrients, such as amino acis, minerals and vitamins have top priority in human nutrition. In consequence of the high need of limited resources and some emissions farm animal husbandry is questionable from various views and many people ask for alternatives. Based on a stocktaking of the traditional production of edible ptotein of animal origin, the paper analyses potentials for improvement of traditional ways of plant and animal production and new possibilities of protein manufacture. Furthermore, possibilities to avoid food competition between humans and animals, the reduction of land, feed and food losses as well as changes in the consumption behaviour of men and the avoidance of over consumption and overweight up to the present stage of aquaculture were analysed. Finally, imitated food based on plant products with adequate additives, single cell protein, insects and so-called lab grown (cultured) meat are discussed; further research needs are outline and future potentials are shown.
