Research Abstract

A secretion of oyster shell was collected from braked shell about center of gill which had a high activity of ciliary movement. It was white material and contained mainly calcium carbonate. In this study, it was used as safe antiseptics in order to hold freshness of shucked oysters. When shucked oysters were dipped for 15 min into 0.05% (w/v) of the secretion in an artificial sea water, inhibitory effects against the growth of food-borne bacteria were revealed. By analysis of absorbance at 250 nm in the supernatant of suspension, it is considered that the nucleic acids of bacteria were flowed out in order to break down cell membrane of bacteria. Moreover a simple spectroscopic method based on ciliary movement of oyster gill was developed for evaluating the freshness of oysters as raw food.
