Abstract

Purpose: This study addresses the problem of using synthetic Adhesives for Paper restoration. It suggests the use of traditional Adhesives instead. The paper discusses the wide range of the use of serish (Eremurus paste) in Iran, including for applying on paper. The study provides methods to increase the viscosity and viscidity of serish. method and Research design: Tradional methods of extraction include Enzyme stabilization, and Polysaccharide extraction were applied separately as well as simultaneously on fresh serish roots and serish powder. Then the quality of produced samples was examined. Boiling 70% Ethanol was applied to stabilized enzyme and sticky Polysaccharides were extracted using 96% Ethanol. Extracted Polysaccharides were dried using freeze drying method. Then, 2% solutions of these Adhesives were prepared. The viscometry, UV-Vis spectroscopy and pH metery were examined on the produced Adhesives several times and was compared to the traditional serish paste. Findings and Conclusion: Stabilizing methods were effective as the viscosity and viscidity of the extracted Adhesives increased. However, the extraction process using just Ethanol was not effective enough. Extracting Polysaccharides after stabilizing enzymes led to the best result, as not only the viscidity and viscosity tured to be at the highest level, but the pH and brightness of Adhesive increased.
