The purpose of this study is to compare preferences of consumers between food items made from modified cassava flour and plain flour using sensory tests. This study is a qualitative research with an experimental approach and four food items, namely streamed brownies, cookies, fried mushrooms, and seasoning flour have been used for the study. Each of these food items are made from modified cassava flour and plain flour. Panelists wore blindfolds and tasted the food items except the seasoning flour. Based on the data analysis, the panelists have different preferences towards the four food items. The result of the paired Wilcoxon test showed that there is not any different preference in terms of taste of steamed brownies made from mocaf or plain flour, while there is a significant difference in terms of color, aroma, texture, and appearance between the steamed brownies made from mocaf and plain flour. Consumers decide to buy products made from mocaf because these products use local flour and are gluten-free. This article describes the customer's preference based on sensory analysis between products made from mocaf and ones made from plain flour. The result can be used as the basis for developing food items made from local flour and alternative food for customers allergic to gluten.

This study investigated women's magazines and women's food consumption stories of the 1950/s. That is, it attempted to comprehend the connection between the public and private aspects of food consumption as discussed in the 1950's. The public aspect of culture was investigated using the women's magazine "Yeo-won" which reflected the social and intellectual hegemony of the time. The private aspects of culture were investigated by reviewing the daily life of women though in-depth interviews. Mass media reflected the social and intellectual hegemony and indicated that a cultivated woman who supported western food was a wise mother and a good wife, and that a woman who consumed flour-based food was a reasonable and modern consumer, ahead of her time The admiration for the U.S. and its advanced civilization through free handouts of flour and powdered milk accelerated the consumption of industrialized flour-based foods such as noodles, hardtack, and steamed bread. This lead to the rigid traditional food-eating habits of boiled rice, and side dishes changed to flour-based and processed foods. That is, food represented a cultural identity.

The effects of heat-moisture treatment (HMT) on rice flour (RF) have been investigated for possibility of texture modifier in protein-based foods matrix, tofu. The optimum condition for preparation of tofu with maximum textural parameters was investigated by using response surface methodology (RSM). Rice flour was subjected to moisture content (10-30%) and heating temperature (100-140℃). Based on the response surface and superimposed plots, the optimized conditions of hydrothermally treated rice flour was as followed: moisture content, 22%; temperature, 130℃, which showed lower swelling power as compared to native RF and became more stable during continuous heating and agitation than native one. Tofu, prepared with HMT-RF, showed a denser network structure than that with RF, thereby inducing an increase in textural parameters. From the above results, the addition of HMT-RF could preserve the quality of tofu and be useful for developing an acceptable protein-based food product.

The purpose of this study was to investigate the effects of skate (Raja kenojei) flour on the functional and sensory characteristics of Mandupi. Mandupi samples were prepared with wheat flour along with the addition of different amounts of skate flour, followed by functional measurements and sensory evaluations. According to the amylograph data, the composite skate flour-wheat flour samples had increased gelatinization temperatures with increasing skate flour content; whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of color values, L and b values decreased, but the a-value increased with increasing skate flour content. Furthermore, the addition of skate flour increased hardness, springiness, chewiness, and adhesiveness in the samples. Overall, based on sensory evaluations, the Mandupi containing 5% skate flour was preferred over the other samples.

Purpose: In this study, we evaluated the physicochemical and sensory effects of glutinous rice flour substitution in Yakgwa. Methods: The glutinous rice flour was added to Yakgwa dough as ratio to ranging from 0, 20, 40, 60%. Dehydration, oil absorption, color, texture and preference properties of Yakgwa were then investigated. Results: Glutinous rice flour caused a decrease in dehydration and oil absorption during frying. For color determination, L-value increased while b-value decreased as the addition of glutinous rice flour increased. In the instrumental texture analysis, hardness and chewiness increased with increasing glutinous rice flour content. Yakgwa with 20 or 40% glutinous rice flour showed a significantly higher overall acceptability than others. Conclusion: It can be concluded that 20 or 40% glutinous rice flour substitution is appropriate for preparing Yakgwa, based on the sensory evaluation results.

The sensory characteristics of cream soup containing 0, 25, 50, 75 and 100％ rice flour were investigated in order to develop a new processed food using rice. The Hunter L(lightness) value increased with the amount of rice flour, while the a(redness) value and b(yellowness) value decreased, significantly. The viscosity of rice cream soup significantly decreased with the increasing amount of rice flour. Based on the sensory evaluation, the cream soup samples with larger rice flour component showed a higher clean taste score, while those with the least rice flour resulted in higher darkness, viscosity, greasy taste, md softness. The overall acceptance was the highest in the cream soup with 75％ and 100％ rice flour. In terms of the color and viscosity, good correlations were observed between the sensory evaluation and the objective analysis. The overall acceptance showed a significant positive correlation with a clean taste, while there was a negative correlation with a greasy taste and the viscosity measured by a viscometer.

Jeolpyon rice cake was made using buckwheat flour and measured its texture, color and sensory properties as follows. According to the amylograph guage test, rice flour was the highest in its initial pasting temperature $82.5^{\circ}C$. With 5% addition of buckwheat flour, it came to be $81.0^{\circ}C$ and became $79.5^{\circ}C$ at 10%, and $78.0^{\circ}C$ at 15%, which was lower than the control. And its maximum temperature at peak viscosity showed at $87^{\circ}C$ and it showed no difference in temperature according to the amount of buckwheat flour. The maximum value (peak point) was 690 BU in control and it increased following to the added amount of buckwheat flour, 710 BU in adding buckwheat flour 10% and 740 BU in 15% of buckwheat flour. In relating to the changes of texture, it became hard by the added amount of buckwheat flour because of decreasing cohesiveness and springiness, but increasing gumminess and brittleness. The hardness increased by adding with buckwheat flour through the freeze preserving period. But adding buckwheat flour of 10% decreased the hardness. Regarding the color value, lightness decreased by the adding buckwheat flour, but a and b value increased. As a result of the sensory analysis about Jeolpyon prepared with buckwheat flour, the most favoured ratio of buckwheat flour for color and preference was at 10%. In case of 15%, it was a little dark so it was not desirable. Based on the above test, the best combination ratio of buckwheat for Jeolpyon was 10%. And Jeolpyon can be easily made at home as well as mass production due to relatively simple making procedure.
