تأثير التغيرات الفصلية في مردود كاراجينان الطحلب البحري Hypnea musciformis و صفاته في المياه السورية

Abstract EN

Seasonal changes effect on yield and quality of carrageenan from the Syrian marine alga Hypnea musciformis were studied during 1 year.

The carrageenan yield varied from 31 to 46%.

The maximum yield was recorded between April and September, while low carrageenant content was recorded in December.

The gel strength of carrageenan was maximum in September (260 g/cm²) and minimum in March (90 g/cm²).

The viscosity ranged from 22 to 44cP with a peak recorded in September.

Seasonal variations were not observed in the gelling (42-50 C°) and melting (60-70 C°) temperatures of carrageenan.

The results indicate that Hypnea musciformis can be considered a good sources for production of commercial carrageenan in future.
