A fermented squeezed-type paste was manufactured for the purpose of effective utilization of cockle shell by-product, and their rheological properties, texture and storage stability were investigated. The contents of moisture, portein, lipid, carbohydrate and ash in the fermented product were 57.7%, 3.2%, 2.4%, 17.6% and 19.3%, respetively. When storage at 90 days, the contents of chemical composition were little changed. During the storage period, pH and salinity were 6.3~6.6 and 20.3~20.65%. And the product was stable for the storage of 60 days at 23±3℃ on bacterial growth. The major free amino acid in the product were glutamic acid, lysine, leucine, valine and aspartic acid. And during the storage period, orders and contents of amino acid composition were not changed compared with 0 day storage. Thus, fermented squeeze-type cockle shell by-product paste were stable that decomposition was not continued at storage period.
