Changes in the textural properties of rice cookies as a result of using roasted soybean flour (RSF) as an additive were investigated in this study. RSF was replaced as 3, 6, 9, 12, 15 and 20% of 100 g of rice flour. The addition of RSF increased the hardness of dough and cookies as measured by texture analyzer (TA), whereas moisture content of dough and cookies decreased upon addition of RSF. Further, the addition of RSF led to an increase in the L value of dough and cookies, but to a decrease in the a and b values. In addition, the bulk density of cookies decreased upon addition of RSF, whereas bulk density of dough also declined when compared to control. The spreadability of cookies was found to be lower in comparison to control. The values of ${\Delta}bulk$ densities (BD) and ${\Delta}hardness$ of cookies also increased upon addition of RSF. From the point of view of sensory evaluation, addition of 9% RSF to rice cookies showed the highest score in terms of overall acceptability and softness. A 12% RSF addition to rice cookies led to the highest score in sandiness. As a result, we conclude that the crispy texture of the rice cookie can be improved by adding RSF.

The purpose of this study was to develop Zingiber officinale Roscoe powder(ginger powder) sweet rice muffins. The process included substituting sweet rice flour for cake flour and adding ginger powder. The mixing conditions for the ginger powder sweet rice muffins were a control and three levels of ginger powder (A), whole egg (B), and soybean oil (C) using central composite design, and were optimized by response surface methodology. The optimization was analyzed with regard to physical, textural, and sensory properties. Among the sensory properties, variables that appeared to show significant values, such as appearance, flavor, softness and overall quality were used to identify optimums. The numerical and graphical methods used in this study determined that the optimum formulation for ginger powder sweet rice muffins was 8.39 g of ginger powder, 215.37 g of whole egg, and 54.40 g of soybean oil. Ginger increases appetite, enhances metabolism and reduces the speed of aging. These health advantages of ginger provide evidences that ginger powder sweet rice muffins are a good healthy snack, particularly for the elderly.

This study evaluated the impact of storage temperature on the quality characteristics of texturized vegetable protein (TVP). TVP was prepared by mixing defatted Daewon soybean flour at 80℃, gluten, and corn starch in a 5:3:2 ratio, which was then extruded at a screw speed of 250 rpm and a barrel temperature of 190℃ with moisture addition at 9 rpm. Subsequently, the extruded TVP was vacuum-sealed in polyethylene packaging and stored at -20℃, 0℃, and 4℃ for 9 days. Texture analysis revealed that the curing rate followed 4℃ > 0℃ > -20℃ sequence. No significant color variation was observed across the storage conditions, although water content increased at all temperatures. Notable changes were detected in moisture absorption capacity (%) and solid leaching (%), following the order of -20℃ > 0℃ > 4℃. The turbidity of the solution released during cooking varied, with the highest to the lowest sequence being -20℃ > 4℃ > 0℃, while pH levels remained neutral. Regarding free amino acids, sweetness and textural quality improved with storage across all temperatures, whereas bitterness components diminished at 4℃. The study suggests that refrigerated storage at 4℃ is a viable method for distributing TVP, which was previously distributed only in a frozen and dry state.

Northern Kyungbuk around Andong is a mountainous and more or less dry region geomorphogically. Since this area located in the valley was less invaded by foreign countries, the folk traditions have been maintained for a long time. Also as the center of Confucian culture, this region respects ceremonies and so, the simple and noble ceremonial-foods such as Ddok, Hankwas, and Buchiki have been firmly preserved in many distinguished families. And besides Andong-Soju, many traditional liquors produced in different methods can be found in this region. As Gogi-Sikhae(a fermented beverage utilizing rice and fish) is still preserved in eastern coastal area, Sosikhae(Sikhae without fish) is maintained in this region and furthermore the unique Andong Sikhae developed by modifying Sosikhae is being consumed currently. Since it is difficult to get fish here geographically, the soybean foods were developed for protein intake, for example, various fermented soybean pastes, Andong-Songuksu(a hand-made noodle using raw soybean flour), and Siragiguk(a vegetable soup).

We investigated the physicochemical and sensorial properties of hamburger patties made with three different defatted soybean flour (DSF) preparations which differed in particle size. Coarse ($Dv_{50}=259.3{\pm}0.6{\mu}m$), fine ($Dv_{50}=91.5{\pm}0.5{\mu}m$), and superfine ($Dv_{50}=3.7{\pm}0.2{\mu}m$) DSF were prepared by conventional milling and sifting, followed by jet milling at 7 bars. Hamburger patties containing 5% of each DSF were prepared for a property analysis. The hamburger patties made with 5% superfine DSF showed the lowest cooking loss among the treatment groups (p<0.05). The patties with superfine DSF also retained the texture profile values of the control patties in terms of hardness, gumminess, springiness, and chewiness, while the addition of coarse and fine DSF increased the hardness and chewiness significantly (p<0.05). The sensorial results of quantitative descriptive analysis (QDA) indicate that the patties containing superfine DSF were softer and tenderer than the controls (p<0.05). Although the overall acceptability of the patties made with coarse and fine DSF was poor, the overall acceptability of the superfine DSF patty was the same as that of the control patty. These results suggest that superfine DSF is an excellent food material that can supply dietary fiber, while maintaining the physical characteristics and texture of hamburger patty.

This study was carried out to investigate the effect of soy protein dispersibility on the bread making properties when Doenjang powders (DP) were added to the bread formula at the levels of 2.5 or 5.0%, comparing with full fat (FSF) or defatted (DSF) soy flours which contain same protein contents as those of DP. Protein dispersibility indices (PDI) for DP, FSF, DSF and strong wheat flour were 57.1, 7.3, 10.8 and 32.8%, respectively. Addition of DP decreased significantly the resistance to extensibility of wet gluten and increased its extensibility. However, FSF and DSF showed different changes in gluten rheology due to their PDI. In correlation coefficient values, PDI affected positively both gluten extensibility (r=0.98, p<0.01) and ovenspring (r=0.88, p<0.05) resulting in loaf volume and texture improvement of bread with addition of DP.

There were fifty two kinds of fermented soybean sauce before 17th century thirteen recorded in ${\ulcorner}$Sangayorock${\lrcorner}$, two in ${\ulcorner}$Sasichanyo${\lrcorner}$, one in ${\ulcorner}$Yongjechongwha${\lrcorner}$, nine in ${\ulcorner}$Soowonjabbang${\lrcorner}$, one in ${\ulcorner}$Domoondaejak${\lrcorner}$, six in ${\ulcorner}$Dongyoebogam${\lrcorner}$, four in ${\ulcorner}$Gushangchalyo${\lrcorner}$, five in ${\ulcorner}$Guhwangboyubang${\lrcorner}$, two in ${\ulcorner}$Yorock${\lrcorner}$, four in ${\ulcorner}$Chisengyoram${\lrcorner}$ and five in ${\ulcorner}$Joobangmoon${\lrcorner}$. These books had thing to know when making fermented soybean sauce like kinds of soybean sauce, how to make it, its ingredients and quantities to be used, how to make fermented soybean sauce in haste, and how to remake wrong made fermented soybean sauce, etc. Before 17th century, fermented soybean malt was divided into two kinds the only soybean malt and the mixed soybean malt that had bean, wheat, wheat flour and wheat bran. The bean only soybean malt was further divided into mashed soybean malt (Beans were steamed and mashed into past.) and unmashed soybean malt (Beans maintained their shape without being mashed.) while mashed soybean malts were made in Winger, in January of February, unmashed and mixed soybean malts were made in Summer, in July. When made fermented soybean sauce, mashed and unmashed soybean malts were used as they were and mixed soybean malt was dried and powdered for use. Fermented soybean sauce before 17th century could be classified by the features of soybean malts being used, Normal fermented soybean sauce was made from bean only soybean malts and other ingredients. Shi(시) was made from unmashed soybean malts, in which beans maintained their shape, and Gowhajang and Jeupjang were made from mixed soybean and wheat bran. Fermented soybean sauce was also made from old fermented soybean sauce, yeast. water leftover after boiling bean leaves, and soybean chaff without soybean malt. There were also side dish type soybean sauce like Kongjaban today and fish and meat sauce made from flesh ingredients. To make fermented soybean sauce in haste, the soybean sauce was heated. Beside there were how to maintain fermented soybean sauce and how to remake wrong made fermented soybean sauce.

Dasik is a type of Korean traditional confectionery that is kneaded with various grains, nuts or herb flour and honey and then pressed with a decorative press. Soybeans are a rich in protein, lipids, dietary fiber, minerals and fat soluble vitamins. Spirulina is a functional food that contains protein, lipids, carbohydrates, minerals, vitamins, dietary fiber and pigments. In this study, soybean Dasik containing spirulina was developed in an attempt to provide an easy method of incorporating spirulina into daily dietary life. In addition, we evaluated the quality characteristics of the soybean Dasik with spirulina that was developed here. Specifically, 0, 10, 20 and 30% spirulina was added to the soybean powder that was used to prepare soybean Dasik. Soybean Dasik that contained 30% spirulina had a higher moisture content and lower hardness when compared to other groups. In addition, the L, a and b value decreased as the level of spirulina increased. Furthermore, the antioxidant activity of soybean Dasik increased according to the increase in the addition of spirulina. Specifically, the $IC_{50}$ values of the DPPH and hydroxyl radical scavenging activity of the control group were 76.6 mg/mL and 100.7 mg/mL, respectively, whereas these values were 26.3 mg/mL and 32.9 mg/mL, respectively, in Soybean Dasik that contained 30% spirulina. When a sensory evaluation was conducted, the overall preference decreased as the level of added spirulina increased. When the buying intension was evaluated, the control group had the highest score (7.8), followed by that of the Dasik that contained 20% spirulina (7.2) The buying intention was lowest for the Dasik that contained 30% spirulina. In conclusion, Soybean Dasik that contained up to 20% spirulina would be maketable.

This study was conducted to examine the effects of feeding diets containing bioorganic power (BP) flour, wheat flour and rice flour on blood glucose and lipid level in streptozotocin-induced diabetic rats. BP flour was composed with the mixture of defatted flour (16 g soybean, 12 g wheat, 8 g barley), 2 g red ginseng and 2 g whole wheat flour per 100 g diet. Experimental groups were divided into non-diabetic normal and 4 diabetic groups containing control, 40% BP, 41.6% wheat and 41.6% rice flours with basal diet. BP group was significantly increased body weight gain and decreased plasma glucose compared with the diabetic control, wheat and rice flour groups (p<0.05). Food efficiency ratio of diabetic rats were significantly lower than that of the normal rats. The concentrations of total cholesterol and triglyceride in plasma and atherogenic index were significantly decreased in BP, wheat and rice diabetic groups than diabetic control (p<0.05). The concentration of total cholesterol and triglyceride in liver was significantly lower in BP group as compared with the diabetic control, wheat and rice flour groups (p<0.05). In conclusion, the results indicated that BP flour feeding improved plasma glucose level, total cholesterol and triglyceride in diabetic rats.
