Hasma H., . Lipids associated with rubber particles and their possible role in mechanical stability of latex concentrates. pp. 105-114. ISSN 0127-7065
Abstract
Lipids which form one of the major membrane components surrounding the rubber particles (RP) in natural latex could play a role in the mechanical stability of the latex on storage in ammonia. Results showed that the main lipid components which changed on storage in ammonia were the glycolipids and phospholipids which hydrolysed to free higher fatty acids (HFA). The amount of glycolipids and phospholipids in fresh RP of six Hevea brasiliensis clones did not vary much. Consequently the amount of HFA generated in each clone was expected to be equal. The mechanical stability time (MST) of the six clonal latices however differed significantly some giving MST well above 1000 s while some gave MST below 300 s even after three months' storage. This led to the conclusion that formation of HFA is not the major factor contributing to the increase in MST of high ammoniated (HA) latex concentrates contrary to what has been reported previously.
