The possible effect of the proteolytic activity on emulsifying properties of squid ( Illex argentinus ) mantle actomyosin stored at 2-4°C and the effects of cocktail of protease inhibitors [phenylmethylsulfonyl fluoride (PMSF), iodo acetic acid (IAA) and ethylene diamine-tetra acetic acid (EDTA)] were investigated. Oil/water emulsion and their stability were studied by optical characterization using a vertical scan analyzer. The particle size distribution of emulsions was obtained with a particle analyzer. O/W emulsions formulated with actomyosin of squid mantle with inhibitors showed certain stability during the first 15-20 min, and then destabilize during the analyzed remaining time, reaching BS (Backscattering) of approximately 20% with no significant changes thereafter. However, in emulsions formulated with actomyosin without inhibitors, the decrease in BS was recorded at 30-.. View More»
