The Chunma requires a simple pre-treatment, due to the inconveniences of preservation, toxicities, and pungencies in intact state. Various steaming conditions were examined to establish the anti-oxidative characteristics of Chunma using the Response Surface Methodology (RSM). Total phenolics and electron-donating ability were optimal at 94.43 and $101.67^{\circ}C$ for 42.38 and 41.09 min, respectively. Anti-oxidative (Al) and nitrite-scavenging ability were optimal at $100^{\circ}C$ for 40 min. Optimal steaming conditions were determined as 96{\sim}107{\circ}C$ for $28{\sim}46min$ min, almost identical to the predicted conditions of $100^{\circ}C$, 40 min determined using the superimposed contour map. Anti-oxidative activities (AI) under the optimal conditions were $95.9%{\sim}115.6%$ of those determined under predicted conditions, an indication of the high reliability of the calculated values.

Gastrodia elata blume (GEB) is considered to be a useful herbal medicine in oriental countries for the treatment of headache, migraine, dizziness, childhood convulsion, epilepsy, rheumatism, hypertension, neuralgia and neurological disorders. This study was carried out to investigate the quality of bread added with the powder of GEB. The possibility of GEB wheat flour mixture as bread was studied by adding 0%, 0.5%, 1.0%, 1.5%, 2.0% of GEB powder to wheat flour. In Farinograph data, the dough stability decreased with the increase of GEB powder. Granular size of starches ranged from $36\;{\mu}m\;to\;60{\mu}m$, and the shape of them showed a long oval figure. Amylograph showed that the increase in the ratio of GEB on the doughs slightly elevated in the maximum viscosity. The loaf volume of 0.5% powder increased by 10.2% but that of 2.0% decreased by 16.8%. The moisture content was 43.57% in the control but it increased as the powder addition. The colors of crust and crumb were not significantly different among L, b and ${\Delta}E$, but 'a' value in crumb was increased as the powder addition. The addition of the powder had no significant effect on bread texture. In sensory evaluation, the moistness increased as the increase of the powder addition. The control bread was most excellent, and the bread made by mixing additives were better than just 0.5% GEB-wheat flour in terms of quality.

Effects of Gastrodiae Rhizoma on serum lipids and body fat in rats fed high-fat diet supplemented with 10% (w/w) lard during 11-week experimental period were investigated. Ninety-six male rats were randomly divided into eight groups: A, negative control (lard 10%); B, positive control (lard 10%+rat chow+5 brix water extract); C, lard 10%+1% G. Rhizoma powder; D, lard 10%+5% G. Rhizoma powder; E, lard 10%+2 brix 50% ethanol extract; F, lard 10%+10 brix 50% ethanol extract; G, lard 10%+2 brix water extract; H, lard 10%+10 brix water extract. Body weight gain, although slightly higher in groups A, B, and G, did not differ significantly among dietary groups. Weights of liver, spleen, kidney, and testis were significantly higher among dietary groups. Serum total cholesterol and triglyceride concentrations were markedly higher in both control groups than group H (p<0.05). Serum HDL concentration was significantly higher in group E, and lower in group A (p<0.05). Serum LDL+VLDL concentration was significantly lower in groups E, G, and H (p<0.05). Serum testosterone level was slightly higher in groups E, D, and H. Blood glucose level was significantly higher in groups B and G, whereas lower in group H (p<0.05). Epididymal fat pad (EFP) was markedly higher in control groups than G. Rhizoma diet-fed groups (p<0.05). The results indicated that decrease in serum lipids (TC, TG, LDL+VLDL) and body fat, and increase in serum HDL and testosterone levels were higher in groups E and H extracts than groups fed G. Rhizoma powder.

The Chunma (Gastrodia elata Blume) requires a simple pre-treatment, due to inconvenience or preservation, toxicities, and pungencies in intact state. Various drying conditions were examined to establish the physicochemical properties of Chunma by the response surface methodology (RSM). Weter activity and total phenolic acid contents of Chunma dried extracts were optimal at $79.56^{\circ}C$ and $79.64^{\circ}C$ for 7.17 hr and 8.74 hr, respectively, for their characteristics. Electron-donating ability and nitrite-scavenging activity were optimal at 79.79 and $7.99^{\circ}C$ for 8.57 and 8.07 hr. We generated a regression equation for each variable and then superimposed the optimal condition in acquiring values for each frying process factor, physicochemical properties, resulting in that the optimal drying condition was at $75{\sim}80^{\circ}C$ for $8{\sim}9 hr$.
