  • Barley is a main food source, along with rice, in our dietary life that is easy to buy and process. It is required to develop a beverage base and barley syrup for desserts in order to raise utilization of barley beyond its present use in Sikhye (sweet fermented rice drink) and Jocheong (grain syrup) production. In pursuit of the goal to increase the usability of barley as an ingredient of processed food, this study examined the optimal preparation conditions of barley mash for barley syrup. In addition, the study prepared a barley syrup using saccharified barley liquid, analyzed quality characteristics, and conducted a sensory evaluation. Saccharified barley liquid(barley mash) was prepared with ratios of adding malt of unhulled barley germinated as 0 g(CON), 10 g(BM10), 20 g(BM20), and 30 g(BM30). The results of measuring pH under the varied conditions of saccharification temperatures from $50^{\circ}C$, $60^{\circ}C$, and $70^{\circ}C$, as well as time from 1 to 8 hours, treveal that the optimum condition for malt saccharification is $60^{\circ}C$ for 5 hours. By adding oligosaccharides and lemon juice to the saccharified barley liquid at the different ratios of added malt, this study measured quality characteristics(color value, viscosity, pH, sweetness) of barley syrup warmed up for 1 hour. As the result of measuring color in the barley syrup prepared by saccharified barley liquid, higher levels of added malt saw L-value decreased while a-value and b-value both increased. BMs30 showed the highest viscosity of $1,202.67{\pm}3.06$. As for pH, BMs30 was the highest at pH $3.57{\pm}0.02$. The result of the sensory evaluation of barley syrup showed the superior sensory characteristics of BMs20 in terms of color, flavor, sweetness, viscosity and overall quality.

  • This experiment was conducted at college of Agriculture and Life Science in Chungnam National University from September, 2004 to June, 2007 in order to evaluate the mixture possibility between barley and rye in the area of Daejeon. Rye (cultivar; Koolgrazer) and barley (cultivar; Daeyeon Bori) were set for the experiment. The experiment was arranged in four treatments: R100 (rye 100%), R60 + B40(rye 60% + barley 40%), R50% + B50% (rye 50% + barley 50%), and R40% + B60% (rye 40% + barley 60%). The experiment was repeated three times in the randomized complete block. The average dry matter (DM) yield for three years of R100 weighed 9,282 kg and its DM yield was higher than any other DM yield. The higher the barley seed rates are, the lower the DM yield is (p<0.05). As the barley seed rates increased 40%, 50%, and 60% respectively, its vegetative percentage tended to increase 30%, 41%, and 47%, but the barley vegetative percentage against its seed rates did bring forth somewhat low results. Compared with R100, the contents of crude protein (CP) and in vitro dry matter digestibility (IVDMD) got higher as the barley seed rates became higher, while the contents of NDF, ADF, cellulose, and lignin were lower (p<0.05). Compared with R100, the yields of crude protein dry matter (CPDM) and digestible dry matter (DDM) showed lower in the any mixed barley (p<0.05). Thus, in case of using barley mixed with rye in the area of Daejeon, it seems to be quite difficult, unless the supply of high-productive barley variety is followed, to enhance the yields of DM, CPDM, and DDM.

  • This study investigates waxy barley powder substituted for wheat flour in bread recipes with the amounts of 0%(control), 5%, 10%, 15% and 20%. Waxy barley powder consisted of 8.33% of moisture content, 10.47% of crude protein, 1.63% of crude fat, and 2.97% of crude ash. Sedimentation value and pelshenke value have decreased as the waxy barley powder content increased. The farinograph measurement result of the bread made with waxy barley powder showed that consistency, water absorption, development time, stability and time breakdown have increased as the waxy barley powder content increased. The amylograph measurement result of the bread made with waxy barley powder showed that T have increased as the waxy barley powder content increased. Their P, H and P-H have decreased as the ingredient contents increased. Baking loss and specific loaf volume have decreased as the waxy barley powder content increased. The chromaticity measurement result of the bread made with waxy barley powder showed no significant difference as the waxy barley powder content increased. The texture measurement result showed that the hardness and gumminess of bread have increased as the waxy barley powder content increased. Their cohesiveness, springiness and chewiness have decreased as the ingredient contents increased. Overall preference scores showed a high acceptability for the bread made with 10% waxy barley powder.
