| Abstract |
This study is concerned to the microbial population and its effects in the fish paste products. Experimental results were summarized as following orders ; 1) The number of bacteria in accordance with raw materials and coocking site was known to as ; Wheat flour - 7.0 × 10^8/gram , Brayed fish meat - 2.0 × 10^7/gram, Cooking table - 6.1 × 10^6/1.54㎠, Chopped fish meat - 4.1 × 10^6/gram, Wooden plate - 5.5 × 10^5/218.32cm, Sodium chloride - 8.8 × 10^4/ gram, Wheat starch - 4.5 × 10^4/gram, Fish meat - 2.3 × 10^4/gram. However, there were a few bacterial numbers less than 300 per gram of raw materials, such as monosodium glutamate, tap water, sugar, saccharine and eggs. 2) Bacterial population in the raw materials might be changed according to the conditions of preservation. 3) When the heat treatment is used for the preservation, the thermal effects were rarely found at the interior part of fish paste products. Conduction of heat into the interior part dose not rise about 84℃ and the survival of bacteria could be possible under the condition. Therefore, cooking being used requires further studies. 4) Number of bacteria in the fish paste products sold in the market was higher on April and May than those on June. Especially on June, the number of bacteriz in the interior part were found higher than those in the exterior part of the products. |
