Four thin-layer drying models were investigated for the description of FIR-assisted freeze-drying characteristics. The models were exponential model, Page model, diffusion model, and approximation of the diffusion model. Tests were conducted using a three-level, three-factor (drying temperature, distance between sample and FIR heater, and sample thickness) design, and quadratic polynomial analyses were performed to relate the drying parameters of thin-layer drying model. The performance of these thin-layer drying models was evaluated by comparing the coefficient of correlation (R2), the sum of squares, and the RMSE amongst four models. Drying parameter K of the Page model gave the best results in describing freeze-drying with FIR of Tylose and sweet potato.

In this study, we investigate the heat-induced inhibition of drug-metabolizing enzyme activity in mice fed with freeze-dried, heated freeze-dried or half amount autolyzed freeze-dried Brussels sprouts powder. 0.5% ethoxyquin diet was fed to another group of mice as a positive control. The study mice, four per group, were fed a diet consisting of 20% Brussels sprouts for 7 days. Each group had its own pair-fed group. We found significantly greater inductions of glutathione S- transferase, quinine reductase, and phase Ⅱ drug-metabolizing enzyme activities in groups fed within freeze-dried and heated freeze-dried Brussels sprouts than their pair-fed groups. These findings indicate that intestinal microflora still can hydrolyze glucosinolates without plant myrosinase activity, though the alteration of cytochrome- P-450 1A (CYP1A, a phase Ⅰ drug-metabolizing enzyme) induction was only 1.4-fold.
