Wastes from the fruit and vegetable processing industries consist of significant quantities of nutritive fibre, thus, they could become the low-cost and valuable by-product containing cellulose. Nutritional fibre is a dietary substance that improves and regulates the functioning of human body owing to, among other things, its ability to reduce the level of bile, fatty acids, and cholesterol in blood. In particular, the ability of fibre to absorb metals including heavy metals seems to be very promising. On the other hand, in the case of macro- and microelements, this specific property of fibre can reduce the usability of fibre as a food additive. The objective of this research aimed at analysing the potential of a black currant pomace preparation to absorb Cu, Zn, and Fe ions in the context of this pomace being applied as a fibre additive to foodstuffs. The results of the research into Cu, Yn and Fe ions sorption in the acidy environment indicate that the currant fibre binds Cu ions (>68%) relatively the best, whereas the sorption of Fe, an important microelement for human organisms, is the lowest (>7,5%), and that the level of metal sorption is directly proportional to temperature.
