1,1-Diphenyl-2-picrylhydrazyl Radical-scavenging Capacity and Oxygen Radical Absorbance Capacity of Sweet Potato Cultivars with Various Flesh Colors

Nippon Shokuhin Kagaku Kogaku Kaishi, 2009
11品種の有色サツマイモ（白色 : 3，黄色 : 2，橙色 : 2，紫色 : 3）の凍結乾燥品から高速溶媒抽出装置を用いて抽出液を調製し，DPPHラジカル消去能とORACを測定した．サツマイモのDPPHラジカル消去活性は肉色が白，黄，橙では同程度であったが，紫サツマイモは他の肉色のサツマイモと比べて約10倍高い活性を示した．ORAC値もDPPHラジカル消去活性と同様な傾向であり，ETとHATを反応原理とする2つの評価系で紫サツマイモが高い抗酸化活性を示した．20品種・系統の紫サツマイモにおいて，主要アントシアニンの含量とORAC値との間に正の相関（R＝0.833）が認められ，アントシアニンがORAC法での主要な抗酸化成分であると判断された．また ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
