Effects of ingredient ratios of blanc-mange on its rheological properties were studied. The ratio of ingredients which were starch, soybean protein isolate and soybean oil, was settled by the Scheffé’s simplex lattice design. The Amylogram, the gelatinized temperature, the maximum viscosity, the viscosity 10 min. after kept at 95℃, hardness, adhesiveness, and mold-retaining properties were measured, and the relationships between the ingredient ratios and the values of each parameters were fitted into quadratic equation. The predicted quadratic equation was available to decide the ingredient ratios to obtain desirable parameters.
 When the sample was prepared with higher ratio of starch, the sample showed higher values in maximum viscosity, hardness, and mold-retaining property. In contrast, when soybean oil ratio increased, the maximum viscosity, viscosity 10 min. after kept at 95℃, hardness, adhesiveness and mold-retaining were lowered. On the other hand, the ratio of soybean protein isolate did not influence to any rheological properties of the sample.
 Those results indicated that traditionally used starches can be replaced by sago starch and can be used to improve rheometric physicochemical values of the mixture gel.

 Hainuwele myth, which is found among the Wemale in Ceram Island, Morucca, is famous as a story explaining the origin of planting root crops. It tells how people began cultivating root crops, such as taro and yam. The Arafundi and the Kaningara in the Upper Karawari, East Sepik, Papua New Guinea, have several myths and folklore which explain the origin of utilizing sago palms for carbohydrate. This paper examines these myths and folklore comparing with the Hainuwele myth. The findings are as follows. 1. There is a similar structure among these myths. 2. Although Hainuwele myth explains the origin of root crops, the myths in the upper Karawari do not explain the origin of sago utilization, but only explain the beginning of cooking sago. 3. The reason of this difference may be explained by the fact that the people in the upper Karawari do not recognize sago utilization as a form of agriculture. 4. The similarity found between these myth may reflect that the people in the upper Karawari used to depend on root crops as their main food, and that they had to adapt their life to sago utilization when they settled in the Sepik area. 5. In the myths and some folklore in the upper Karawari, we find impoverishment and inversion of the Hainuwele myth. 6. We even find the distortion of the structure in the folklore which explains the origin of Australian people.
