To provide the basis of the study on marine animal muscle proteins, quantitative efficiency of various extraction methods that have been used by investigators was experimentally compared, using water or DYER's 5% NaC1 solution4) as the extractant. The squid or flatfish muscles were extracted with extractants at varying ratios of extractant (ml.) /muscle (g.). The ratios more than 20 were recommended to get a good extractability, except the case of the aqueous extraction of the squid muscle (Fig. 1). Among the various methods which will help the mechanical degradation of the tissue structure, both a blendor equipped with buffle-plate (Fig. 2) and a hand-made blendor9) proved to be useful (Tables 1-4). The single extraction was found to be usable in place of the repeated extractions in the estimation of the relative amounts (Table 5, Fig. 3).
