This article presents the results of studies on the chemical composition of Ahnfeltia plicata and Polysiphonia fucoides. The influence of the quantitative ratio of these algae in the mixture on the yield and quality indicators of agar is shown. It was found that A. plicata contains 13% more sulfated polysaccharides than P. fucoides. It was shown that an increase in the mass fraction of P. fucoides in the mixture does not affect the total and fractional yield of agar, but leads to a deterioration in its quality characteristics. Therefore, it is recommended to remove P. fucoides from the red algae mixture when collecting A.plicata red algae.
