Low molecular weight of hydroxyethyl cellulose to extract proteins in natural rubber latex

The objective of this study is to obtain the protein content in NRL ≤ 50 µg/g of rubber and to evaluate the effect of oligoHEC treatment on the soluble protein content in NRL. The results show that oligoHEC at low concentration (0.25 %) effectively extracted protein molecules. Interestingly, the allergenic protein content in NRL decreased proportionally with the increase in oligoHEC concentration.
