k-carrageenan is a polysaccharide extracted from red algae, and widely used in the food industry. This research was carried out to analyze the yield (% in dry weight) and quality (viscosity) of κ- carrageenan from Chondracanthus chamissoi and Mazaella canaliculatus during the summer and winter conditions, for that, 10 kg of each seaweed were collected on the beach Mendieta, Pisco, Peru; in September 2021 (winter) and January 2022 (summer). They were classified into two phases (gametophyte and tetrasporophyte). Subsequently, k- carrageenan extraction, infrared spectroscopy (FTIR) identification and viscosity measurement were performed. The results obtained in kappa-carrageenan yield, between the two summer and winter seasons, showed significant differences (p-value<0.05) largely in the gametophytic phase of M. canaliculatus, where higher yield was obtained in winter (31.74%) than in summer (24.32%). On the other hand, the gametophytes of C. chamissoi showed a higher yield in the summer season (28.41%) than in winter (23.29%). About the k-carrageenan profile obtained by FTIR, all treatments were identified as kappa-carrageenan due to two representative peaks of this colloid between 920-930 and 846-845 cm-1. In the case of viscosity, there was no significant difference between the stations (p-value > 0.05), but between the species M. canaliculatus and C. chamissoi and their life phases, being C. chamissoi in the gametophytic phase, which presented higher viscosity with 19.60cp and 19.29cp in summer and winter, respectively. Meanwhile, M. canaliculatus showed 17.70 cp in summer and 17.19cp in winter. Therefore, these results will help to determine the best harvest season for the sustainable development of the k-carrageenan industry in Peru.
