This paper presents a new approach to utilization of alkaloid-rich lupin as a high protein and ecological plant. After processing of bitter lupin seeds, many valuable products are obtained, i.e. protein concentrate, high dietary fiber product, raffinose family oligosaccharides (RFOs), and lupin extract. The described debittering process is fully ecological without waste and all obtained products may be utilized in different domains. Therefore, (i) the lupin protein concentrate may be a soybean substitute for feeding animals, (ii) high dietary fiber product improves rheological properties of dough and quality of bakery products, (iii) RFOs are prebiotics, (iv) lupin extract may be used for ecological plant cultivation, as a plant protection preparation and as a medium for the production of yeast, gibberellic acid (GA3), etc.
