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.

본 연구에서는 토마토소스 제조 시 일반적으로 사용되고 있는 루(roux)를 대신하여 멥쌀가루, 찹쌀가루, 감자전분, 타피오카전분을 농후제로 사용한 토마토소스를 제조하였고, 일반성분 및 칼로리, 색도, 염도, 가용성 고형분 및 환원당, 점도 및 관능검사를 실시하여 토마토소스에 가장 적합한 농후제를 밝혀내고자 하였으며, 그 결과 토마토소스를 제조할 때 기존의 루 대신에 감자전분이나 타피오카전분을 사용하였을 경우, 관능적 기호도가 더 높아졌음을 알 수 있었다. 또한 저지방, 저열량의 토마토소스를 제조할 수 있으므로 최근 고지방, 고열량 식품을 기피하는 추세에 알맞은 토마토소스를 제조할 수 있음이 확인되었다. 추후에는 전분을 농후제로 사용한 토마토소스를 조리적으로 접목하여 관능적 특성을 연구하여 그 이용도를 높이는 연구가 진행되어야 할 것이다.

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.

현재 국내 주정공장에서 사용되고 있는 타파오카를 액화 및 당화시켜 얻은 당화액과 당화액에서 분 리된 고형분으로 회분실험과 total cell retention c culture 실험을 하였다. 당화액에 의한 회분 실험결과 에탄올 수율은 0.48 g-ethanol/g- (reducing s sugar)으로서 약 $180g/\ell$의 환원당이 36시간만에 거의 다 소모되어 약 $84g/\ell$의 에탄올이 생성되었다. 이 때 최종 효모농도는 $8.5{\times}107$ cellsjml(약$2.30g/\ell$) 이었다. 원료 중 환원당농도가 $224g/\ell$이고 희석속도가 $0.18h^{-1}$ 인 total cell retention culture 실험에서는 효모농도가 약 $40g/\ell$, 잔류 환원당농도 가 약 $15g/\ell$로서 포도당은 거의 소모된 것으로 나 타났다. 에탄올농도는 약 $81.4g/\ell$로서 이의 부피 생산성이 약 $14.7g/\ell$-h이었다. 원료 중 환원당농도가 $205g/\ell$ 이고 희석속도가 $0.2h^{-1}$이며 bleed가 있 는 cell retention culture 실험에서는 효모의 농도가 약 $22g/\ell$까지 증가하였고 에탄올농도는 $685g/\ell$부근에서 진통하였으며 생산성은 약 $13.6g/\ell$-h이 다. 약 $12g/\ell$의 잔류 환원당 중에 약 $4.5g/\ell$의 포도당이 포함되어 있었다. 타피오카 당화액으로부터 분리된 고형분을 사용한 실험을 통하여 고형분도 기 질로서 효용가치가 어느 정도 있는 것으로 판명되었으며 당화액 발효조와 별도로 고형분 발효조의 개발도 필요한 것으로 생각되었다.
