The irradiation flavor scores in Table V show quantitatively the dependence of irradiation flavor intensity on irradiation temperature for both oxygen-packed and vacuum-packed steaks brought to 4°C. rapidly after irradiation. [Pg.55]

Both Y-AI2O3 and TI-AI2O3 are members of a class of binary oxides in which the oxygen packing is of the cubic close packing type, with the cations situated partly in tetrahedral and partly in octahedral positions. These compounds are called spinels after the mineral spinel which has the composition MgAhC. In spinel Mg2+ occupies tetrahedral and Al3+ occupies octahedral positions. The unit cell of a cubic close packed structure is shown in Fig. 8.5. [Pg.315]
