Additional information

As indicated in Assessment Report prepared in the context of the possible inclusion of the substance in Annex I of Directive 91/414/EEC prepared by the Hellenic Ministry of rural development and food (April 2008):

The Hydrolysed proteins are quickly degraded to more simple metabolites, which do not have any activityer. Waste is only superficial and it easily disappears with a simple wash or with the rainfall action.Their persistence in the environment is very short, without any tendency to bioaccumulation.

The biotic degradation of the hydrolysed proteins results in more simple metabolites called amino acids. These compounds are present in live cells; consequently, they are not considered real waste, since they can be used again by the same live cells in the protein synthesis.

The Animal and Vegetable cells are formed mainly by proteins, which constitute more than the half of the dry weight of the cell. Proteins determine the shape and structure of the cell and also function as an instrument of molecular recognition and of catalysis (ALBERTS, 1986).

Proteins have many different biological functions. The widest group of proteins are the enzymes whose function is about catalysing the biochemical processes that take place in the living organisms.

Moreover, there are proteins of reservation of amino acids such as plant nutrients; transport proteins of specific molecules; proteins that work as essential elements of the motile and contractile systems; protective proteins that are present in the blood of the vertebrates such as antibodies; proteins that function as hormones and, finally, structural proteins (LEHNINGER, 1983).

The proteins that are found in food and eaten by human beings and mammals are normally degraded metabolically by means of enzymatic processes to give rise to more simple metabolites (parotids and amino acids) that are used by the live cells for the biosynthesis of new specific proteins.

Thehydrolysed proteins comes from the enzymatic hydrolysis of the animal tissues. Therefore, they do not cause any danger to human beings and mammals in general. As it has been explained before, proteins appear in all biochemical processes that take place in every live cell being, this way, essential compounds for human life.

Furthermore, hydrolysed proteins are authorized by the EU in order to be used as attractant in the elaboration of baits in combination with appropriate insecticides of the Organic Farming (Regulation EC 1488/97 annex 2, part B). This shows the innocuousness of these compounds, since the practice of this kind of agriculture is very demanding with the use of products that can be harmful to human beings.

The use of the hydrolysed proteins is considered of low danger for the terrestrial and aquatic wildlife and ecosystems in general.

Conclusion on classification

The substance is not classified as dangerous for the environment.
