  • Objective: This study was conducted to investigate the effects of dietary levels of tapioca residue on growth performance, carcass characteristics, and meat composition in Hanwoo steers. Methods: Twenty-eight steers were randomly assigned to one of four dietary groups; T0 (0% tapioca residue), T6.7 (6.7% tapioca residue), T9 (9% tapioca residue), and T12 (12% tapioca residue). Results: Supplementation with tapioca residue had no effect on overall growth performance. The concentration of plasma total cholesterol was higher in T6.7 than in other treatments (p<0.05). Dietary levels of tapioca residue did not affect carcass yield or the quality traits of Hanwoo steers. The lightness, redness, and yellowness of the longissimus muscle of Hanwoo steers were higher in T6.7 than in other treatments (p<0.05). Cohesiveness, gumminess, chewiness, and resilience were lower in T6.7 than in other treatments (p<0.05). Conclusion: The results of the present study indicate that supplementation with tapioca residue does not exert any negative effects on growth performance, carcass characteristics, and meat composition in Hanwoo steers. However, as the dietary level of tapioca residue increased, the intake of concentrate intake decreased, and tapioca supplementation greater than 6.7% did not substantially improved the marbling score.

  • Wood powder is widely used in paperboard mills to increase bulk and reduce drying-energy consumption, but this material also deteriorates paper strength because it interferes with the bonds between fibers. Although there have been many studies done to improve the strength of paperboard containing wood powder, specific applications have not recently been observed in paperboard mills. In this study, we carried out a new approach for improving paperboard strength by developing a new organic filler with the ability to increase the bonds between fibers. The residue of tapioca starch was used as raw material to manufacture an organic filler. The functionalities, including bulk and strength, were evaluated by making handsheets containing either wood powder or tapioca organic filler, or a mixture of the two, and measuring their physical properties. The organic filler showed lower bulk improvement and higher paperboard strength than the wood powder. The mixture of tapioca organic filler and wood powder showed improved paperboard strength compared to wood powder alone. Therefore, tapioca residue can be used as a raw material to manufacture an organic filler for paperboard mills.

  • Tomato sauce were prepared with five different thickening agents including roux (TR), non-glutinous rice powder (TN), glutinous rice powder (TG), potato starch (TP) and tapioca starch (TT) to examine proximate composition (moisture, carbohydrate, crude protein, crude fat, crude ash, crude ash), calorie, color value, pH, salinity, $^{\circ}Brix$, reducing sugar, viscosity and sensory test (attribute difference, acceptance). The results were as follows: Moisture, carbohydrate content were the lowest while crude fat and calorie were the highest in TR (roux). On the other hand, moisture, carbohydrate content were the highest while crude protein, crude fat and calorie were the lowest in TP (potato starch) and TT (tapioca starch). Using potato starch and tapioca starch are supposed to be prepared low-fat, low-calorie tomato sauce. L value was the highest in TN (non-glutinous rice powder), a value was the highest in TP (potato starch), b values was the highest in TR (roux). pH of tomato sauce showed a range of 5.24 to 5.39. TG (glutinous rice powder) was the highest and TT (tapioca starch) was the lowest in pH. TP (potato starch) was the highest salinity, reducing sugar was the lowest. TG (glutinous rice powder) was the lowest salinity, $^{\circ}Brix$ was the highest. And TR (roux) was the lowest $^{\circ}Brix$, reducing sugar was the highest. In viscosity, TG (glutinous rice powder) was the highest and TT (tapioca starch) was the lowest. The attribute difference test results was the highest in gloss, color intensity, tomato odor, tomato taste, pure taste in TT (tapioca starch) and savory taste, oily taste, thickness, residue was the highest in TR (roux). The preference test results reveal that the appearance, flavor, taste, texture and overall acceptance level was the highest in TP (potato starch) and TT (tapioca starch). The results of this study, tomato sauce prepared potato starch and tapioca starch instead of the traditional roux was higher in sensory acceptability. Recently, people is avoided high-fat and high-calorie foods, and potato starch and tapioca starch are confirmed that the tomato sauce can be made of a low-fat and low-calorie.

  • In this study, the bioactive activities (antioxidant activity, whitening activity, and anti-wrinkle effect) of dried tapioca-unhulled barley grain residue (TUDDG) obtained after alcohol fermentation, were measured. In the case of DPPH radical scavenging activity, the 50% ethanol extract of TUDDG showed the highest level of about 83% at the concentration of 100 mg/ml, and the ABTS radical scavenging activity was also about 98% of the 50% ethanol extract of TUDDG even at the concentration of 10 mg/mL. In the case of mushroom tyrosinase inhibitory activity, the 50% ethanol extract of TUDDG showed the highest activity at 100 mg/ml concentration of 37%. As a result of collagenage activity inhibition and elastase analysis, the 50% ethanol extract of TUDDG showed high activity with 4.2 mg/mL (IC50) and 26.1 mg/mL (IC50), respectively. Therefore, considering the physiological activity as well as the extraction efficiency of physiologically active substances, the 50% ethanol extract of TUDDG is judged to be highly effective.

  • Batch and continuous cell retention cultures were carried out using tapioca hydrolysate. In batch culture, reducing sugar of about 180g/$\ell$ was almost consumed in about 36 hours, and the concentration of ethanol produced was about 84g/$\ell$ making the ethanol yield 0.48 g-ethanol/g-(reducing sugar). The final yeast concentration was 8.5${\times}$107 cells/ml(about 2.1g/$\ell$). In a total cell retention culture operated with a dilution rate of 0.18h-1, the yeast concentration, the residual reducing sugar concentration, the ethanol concentration, and the volumetric ethanol productivity were about 40g/$\ell$, about 15g/$\ell$, 81.4g/$\ell$, and 14.7g/$\ell$-h, respectively. In another cell retention culture operated with a dilution rate and a bleed ratio of 0.2h-1 and 0.14, respectively, the yeast concentration increased to 22g/$\ell$ and the ethanol concentration oscillated around 68g/$\ell$. The volumetric ethanol productivity was about 13.6g/$\ell$-h and the residual reducing sugar concentration about 12g/$\ell$ containing glucose of about 4.5g/$\ell$. According to the results of batch fermentation using the solid residue from hydrolysate filtration as the substrate, it seemed to have a certain value. Thus, development of an effective reactor system to produce ethanol from this solid residue is in need.
