Abstract

Snail mucin is an ingredient of interest in cosmeceutical and pharmaceutical that is discovered to contain important chemical components such as allantoin, antioxidants, glycolic acid, and vitamins. Among all the land snail species, Achatina fulica is founded as one of the most suitable snail species for heliciculture in Malaysia. In this study, A. fulica mucin was subjected to four storage conditions which were room temperature, 4 °C, with mucin stabilizer and with no added mucin stabilizer for 60 days to study the relationship between different storage conditions and the changes in the chemical/biochemical properties of A. fulica mucin. The chemical characterization tests were Bradford assay on protein determination and cetyltrimethylammonium bromide turbidimetric method (CTM) assay for the study of hyaluronic acid concentration. The microbial test was conducted through the spread plate method and antimicrobial properties were tested using the disc diffusion method. Based on the results, storage of A. fulica mucin at 4 °C with added mucin stabilizer was the most suitable storage condition to preserve the chemical components in the mucin and to provide antimicrobial properties.
