In preceding papers, it was reported that casing with cellophane protected the quality of "Kamaboko" from the microbial contamination from outside. In some experiments, however, it was noticed that micro-organisms developed on the outside of the cellophane used. The present paper deals with the effectiveness of casing with regular cellophane or a water-proof cellophane on which preservatives were smeared. 1. The spraying of the mixture of chlortetracycline(CTC)and dehydroacetic acid (DHA) or butyl-p-oxybenzoate (POB) on the cellophane with which the surface of "Kamaboko" were covered, not only protected the cellophane from the contamination, but also kept the quality of "Kamaboko". 2. The application of casing, prior to steaming, with the cellophane or the water-proof cellophane which was smeared with preservatives dissolved in 10% polyvinyl acetate ethanol solution was more effective than the corresponding casings made after steaming. The application of the water-proof cellophane with CTC and DHA was most effective in prolonging the storage life as long as five days in contrast to two days in the control group without casing. 3. When the casing with cellophane which was smeared with Ca-alginate containing DHA or DHA-Na was applied after steaming, somewhat effective result was obtained, but the result was not superior to a cellophane casing group without the above treatment.
