The research aims to study is to study the effect of the pH factor of Pterocladia
capillacea on agar yield and some of its physical properties using different degrees of pH
(4- 5.5 - 5.5 - 6.5 - 7.5 - 7.5 - 8). The maximum yield of agar was 37.45%
at pH = 5 and
562g / cm2 and viscosity 10.7cP and 15.45% at pH = 8 with the highest strength of 768 g
/cm2 and viscosity of cP 156. The degree of melting and melting of agar Between (22-
33.5 οC) and (75- 86 οC), respectively.
The research aims to study the effect of of agar extraction
temperature (80-90- 100-110 and 120) Syrian alga Pterocladia
capillacea on its yield and and some physical properties.
