  • The effect of enzymatically hydrolyzed vital wheat gluten (EHG) on dough mixing and the baking quality of wheat flour frozen dough was examined. Three different proteases, pepsin, trypsin, and chymotrypsin, were tested individually, sequentially paired, or in combination of all three enzymes. Addition of 1% EHG produced no observable effect on the mixing properties of wheat flour dough. However, addition of 2.5% pepsin-hydrolyzed gluten decreased the mixing tolerance of the wheat flour, and 1% trypsin-hydrolyzed gluten increased the loaf volume of both frozen and non-frozen dough. This finding suggests that trypsin-hydrolyzed vital wheat gluten may serve as a baking additive in replacement for $KBrO_3$ to improve frozen dough quality.

  • This study on the processing of noodles was carried out to increase utilization of Allium fistulosum L., In the areas of total solids in residual liquid, swelling volume, and water absorption, a mixture of 10.0% dried Allium fistulosum L. flour and wheat flour, and a mixture of 25.0% raw Allium fistulosum L. flour and wheat flour both perform similarly to noodles made with just wheat flour. In the area of texture- the gumminess, cutting factor, and chewiness increase as the percentage of dried Allium fistulosum L. flour increases. There is no great difference in these factors between the 10.0% dried and the 25.0% raw mixtures. The color of the noodles with a mixed Allium fistulosum L. flour is green-yellow. As the quantity of Allium fistulosum L. flour increases the color gets darker The over all perception of the noodles made with a mixed Allium fistulosum L. flour was rated higher in color, taste, and smell than regular noodles. This study shows that mixing wheat flour with 10.0% dried Allium fistulosum L. flour or 25.0% raw Allium fistulosum L. flour produces a better noodle product.

  • Rheological properties of the dough made from milled wheat products of various particle size, i.e., wheat shorts, girls and flour, and their effect on the loaf-volume potential of whole wheat bread were investigated in this study. One Korean wheat variety 'Cho-Kwang' was tested for suitability in whole wheat bread. The percent ash and protein content of the milled wheat products were 2.3% and 13.7% respectively. Ranges of 7.3, 5.6 and 4.8 mixograph peak-height were observed in Fraction 1(wheat flours), Fraction 2 (wheat girts) and Fraction 3(wheat shorts), respectively. Dought stability of Fraction 1 did not decreased appreciably as compared to that of commercial first grade baker's flour. Bread-baking test employing a standard formula showed that the wheat grits (0.2-0.5 mm in diameter) appeared to be the limit beyond which a rapid decrease in loaf-volume potential was noted. Optimum loaf volume and crumb characteristics were obtained in 80% wheat grits/20% wheat flour blend.

  • The physicochemical properties and mixograph characteristics of soft white winter (SWW) and club wheat, as well as their product potentiality, were investigated. There were no significant differences between the SWW wheat and club wheat regarding their Single Kernel Characterization System (SKCS) properties. The straight-grade flour yield, break flour yield, ash content, and milling score of the SWW wheat were similar to those of the club wheat, and the straight-grade flour yield had a significant positive correlation to the break flour yield (r = 0.805**). The Rapid Visco-Analyzer (RVA) peak viscosity and swelling volume of the SWW wheat flour were very similar to those of the club wheat flour, and there was a significant positive correlation between the RVA peak viscosity and the swelling volume (r = 0.662**). The average mixograph absorption of the SWW wheat was higher than that of the club wheat. The club wheat resulted in a higher cookie diameter than the SWW wheat, but the difference was not significant. The sponge cake volume using the SWW wheat flour was higher than that with the club wheat flour. In addition, there was a significant correlation between the cookie diameter and the sponge cake volume (r = 0.745**).

  • This study was performed to compare the processing aptitudes of the rice muffins produced from the seven rice varieties, including Goami, Goami 2, Deuraechan, Baegjinju, Seolgaeng, Haiami and Hanareum, along with the use of hydroxypropyl methylcelluloses (HPMCs) as a replacement for the egg white. The water binding capacity of rice flours was significantly higher than that of wheat flour, but its fat binding capacity was lower than that of wheat flour (p<0.05). In the viscosity of the batter, Goami and Baegjinju were lower than that of the wheat flour. There was no significant difference in the specific gravity of Seolgaeng and the batter of wheat flour. The pH of all varieties except Goami 2 was higher than batter of wheat flour(p<0.05). Haiami flour produced higher muffin volume and specific volume compared with the wheat flour muffin. The textural characteristics, the muffins produced by Haiami and Hanareum flours had significantly lower hardness than the wheat flour muffin after 30 hours. All rice varieties except Gaomi 2 showed no significant difference compared to the wheat flour muffin in color, taste and texture (p<0.05). Furthermore, flavor of muffins produced from the Seolgaeng, Haiami and Hanareum flours tested higher than the wheat flour muffin. It was concluded that the rice varieties of Seolgaeng, Goami, Haiami and Hanareum were considered to be the most suitable rice cultivars for the rice muffins.

  • Breadmaking is a complex system in which many variables govern the production of acceptable bread. Lipids, a minor component of wheat flour, function importantly in bread-making. Shortening, or fat, is one of the essential ingredients in commercial baking. Beneficial shortening effect depends on type and quantity of lipids present in wheat flour and also on wheat flour quality. Surfactants have been used in baking industry during last decade because certrain surfactants can replace shortening and/or natural flour lipids. A proper combination of lipidshortening-surfactant is more useful in the production of specialty breads such as whole wheat breads, high protein breads, high fiber breads or even non-wheat composite breads rather than in the production of regular white breads. This presentation is a review of recent studies on the contribution of flour lipids, shortening, and surfactants, alone or in combination in the production of breads; illustrations are mainly from data obtained in the author's laboratory.

  • In an attempt to make dried noodles with composite flours utilizing rice and wheat flours, noodle-making characteristics were improved by the addition of popped rice and wheat flours to rice flour. Their quality was studied in terms of physical properties, noodle-making characteristics, cooking quality test and sensory evaluation. Dried noodle of the composite flour was produced by the conventional method. The results are summerized as follows; 1. In comparing the composite flours, the rice flour containing 30% popped rice flour had a lower maximum viscosity than that with 40% popped rice flour by method of amylograph. The composite flour(20% rice+30% popped rice+50% wheat flour) with added 2% xanthan gum showed the viscosity characteristics which was similar to that of wheat flour. 2. Addition of $1.5{\sim}2.0%$ xanthan gum and $40{\sim}50%$ wheat flour to rice and popped rice flour mixture helped to improve the noodle making properties and the cooking quality, and the noodle making properties and the cooking quality of the mixed flour were almost the same as those of wheat flour alone. 3. The composite flour (rice+popped rice+wheat flour) with xanthan gum showed a higher score in sensory evaluation than that without xanthan gum. The general acceptability scores obtained with the noodle products made of the composite flours with 30% popped rice flour was not significantly different from that of noodle products made of wheat flour alone. However, the noodle products made of the composite flours showed rather higher scores in odor and palatability than the products made of wheat flour alone.
