The total phenolic content, antioxidative activity of blueberry and sea buckthorn by-products were determined using spectrophotometric methods. Physico-chemical methods have been used to determine dry matter, fat, alkalinity and mineral substances. The dried powder obtained from blueberries and sea buckthorn by-products is recommended as a new ingredient for digestive biscuit-type products, the mixture of whole wheat flour and ground oat flakes from the conventional composition being succesfulluy substituted by 10% by-product powder.
