Red ginseng has been considered as a functional food, with much researches on the prevention of cancer, hypertension, arteriosclerosis and constipation having been conducted. In this study, white bread, with the addition of 1, 2, 3, 4 or 5% red ginseng marc powder was measured for its moisture content, volume, height, color, and texture, and sensory analysis was also conducted. The moisture content increased with increasing red ginseng marc powder content. The volume and height of the bread were decreased with increasing red ginseng marc powder content. The crust color, lightness, yellowness and redness all decreased with increasing red ginseng marc powder content. Both the crumb color, and lightness decreased, but the yellowness and redness increased writh increasing red ginseng marc powder content. In the consumer acceptability test, the white bread with a 2% red ginseng marc powder content was shown to have the most favorable quality characteristics.

The rheological properties of some honey-ginseng powder mixturs, used as pharmaceutical pills, were studied extensively by employing five kinds of honey, acacia, chestnut, buckwheat, green perilla and bush clover. Relation between the viscosity of the sample mixtures and the concentrations of ginseng powder and the temperature effect on the internal change of the structure were studied. The results obtained are as follows: 1) A complete gel formation of honey-ginseng mixtures was observed when about 50 days have passed after the sample preparation. 2) The viscosity of honey-ginseng powder mixtures was related with the concentration of ginseng powder, the temperature and the period of time required in gel formation as shown in the following equation. n=noexp$[{\kappa}_{1}c^{n1}+{\kappa}_{2}(T-273)^{-n2}+{\kappa}_{3} t^{n3}]$

It was studied that which components of the ginseng are related to the effects that accelerate Saccharomyces division by comparing the influences of ginseng powder, alcohol extracts of ginseng, and linoleic and stearic acids which are known as the ginseng components on the division. The addition of ginseng powder and alcohol extracts of ginseng to the glucose agar medium marked the conspicuous increases of the division of Saccharomyces: 44% increase by 0.1% powder, 53% increase by 0.05% alcohol extracts. Also, the addition of the fatty acids of less than 0.0008% marked the considerable increases of the division: 22% increase by 0.0008% linoleic acid, 31% increase by 0. 00016% linoleic acid, 12% increase by 0.0008% stearic acid. Therefore it can be concluded that a proper amount of those fatty acids contained in the ginseng has a definite effect on the acceleration of Saccharomyces division.

This study was to investigate the quality characteristics of instant rice cake (Baekseolgi) with different concentrations of ginseng powder by molecular press dehydration (MPD) method. Baekseolgi was cooked using microwave oven, which is a useful cooking method because of reduced cooking time, even though it quickly takes moisture from food surface and lowers food quality. The result indicated that moisture content of Baekseolgi without ginseng powder was decreased; however, there was no significant difference in the Baekseolgi with ginseng powder with increased storage time for 24 hrs. The L value was decreased and a color value was increased with increasing concentrations of ginseng powder (p<0.05). There was no significant difference in the color values within the storage time. The hardness, gumminess, and chewiness of Baekseolgi without ginseng powder significantly changed as the storage time increased; in contrast, those of Baekseolgi with ginseng powder did not show such a significant change. The result of sensory evaluation showed that Baekseolgi with ginseng powder has higher scores in terms of color, flavor, taste, and overall acceptability than Baekseolgi without ginseng powder. Results of this study indicate the addition of ginseng powder to Baekseolgi improves moisture content, color value, and texture properties as well as sensory characteristics.

Color characteristics were investigated for white ginseng powder immediately and during storage following treatments of gamma ray or ethylene oxide (EO) for microbial decontamination. The variation in fatand water-soluble pigments of the sample was negligible immediately after both treatments, however an apparent increase was observed in the samples stored for four months at $25^{\circ}C$ and RH 90%, in the order of nontreated control, EO-fumigated, and 5 key-irradiated samples. Hunter's color a and b values of white ginseng powder increased slightly in proportion to irradiation doses, whereas EO fumigation caused a decrease in L value and an increase in a and b values of the sample, showing overall color difference (${\delta}^E$) of 1.8. Considering the higher ${\delta}^E$ in the higher RH conditions, airtight packaging and sterilization using like gamma ray were considered an effective means for maintaining high quality of color characteristics in stored white ginseng powder.

This study was conducted to develop a optimal composite recipe of a functional cookie including Red Ginseng powder and having the high preference to all age groups. Wheat flour was partially substituted by Red Ginseng powder to reduce the content of wheat flour. The sensory optimal composite recipe was produced by making iced cookies, with 5 levels of Red Ginseng $powder(X_1),\;sugar(X_2),\;butter(X_3)$, respectively, by C.C.D(Central Composite Design) and by conducting the sensory evaluation and the instrumental analysis by Response Surface Methodology(RSM). The results of sensory evaluation showed very significant values in color, appearance, texture, overall quality(p<0.05), flavor(p<0.01) and those of instrumental analysis showed significant values in lightness, redness(p<0.05), spread ratio, hardness(p<0.01). As a result, sensory optimal ratio of Red Ginseng cookie was calculated at Red Ginseng powder 25.4 g, sugar 147.1 g, butter 153.4 g.

Studies were carried out to clarify the effect of ginsenoside-Rbl -Rbr and acid hydrolyzatps of ginsenoside-Rbl, -Rb2 (HRbl, HRbf) on lipolysis and lipogenesis induced by epinephrine, glucagon, ACTH (adrenocorticotrophic hormone), TSH (thyroid-stimulating hormone) and insulin in rat adipose tissilr. HRbl , HRb2 slightly inhibited lipolysis induced by epinephine. glucagon and TSH. ACTH-induced lipolysis in fat tissue slices was significantly inhibited by ginsenoside -Rbl, -Rb2, HRbl and HRb2, particulary HRb2. None of ginsenoside-Rbl, -Rb2, HRbl and HRb2 accelerated insulin-stimulated lipogenesis in fat calls. Among ginseng products, extract powder (freeze dried), extract powder (spray dried), red ginseng powder inhibited ACTH-induced lipolysis in adipose tissue slices, but red ginseng extract not affect them.

The objective of this study was to compare the color and microstructure of powder, redness, brownness, and antioxidative activity in extruded ginseng, white ginseng and red ginseng extracts. The colors of extruded dry ginseng powder (moisture content 30%, barrel temperature $110^{\circ}C$, and screw speed 200 rpm) were similar to those of red ginseng. Intact cell wall structure was examined in dried root ginseng at $70^{\circ}C$ (A), white ginseng with skin (D), white ginseng without skin (E), and red ginseng (F) under a scanning electron microscope. The cell wall was not detected in samples B and C (dry ginsengs extruded with 25% and 30% moisture contents, respectively). Intact starch granules were detected in samples A, D, and E under a scanning electron microscope. Melted starch granules were detected in samples B, C, and F. Colors (L, a, b) of 50% EtOH extracts were similar in samples C and F. Browniness and redness of extracts were high in extruded dry ginseng and red ginseng extracts. Extruded dry ginseng (B) showed higher electron donation ability and phenolic content than the other samples.

Ginseng (Panax ginseng Meyer) has been used as traditional herbal drug in Asian countries. Ginsenosides are major components having pharmacological and biological efficacy like anti-inflammatory, anti-diabetic and anti-tumor effects. To control the quality of the components in diverse ginseng products, we developed a new quantitative method using LC-MS/MS for 13 ginsenosides; Rb1, Rb2, Rc, Rd, Re, Rf, 20(S)-Rh1, 20(S)-Rh2, Rg1, 20(S)-Rg3, F1, F2, and compound K. This method was successfully validated for linearity, precision, and accuracy. This quantification method applied in four representative ginseng products; fresh ginseng powder, white ginseng powder, red ginseng extract powder, and red ginseng extract. Here the amounts of the 13 ginsenosides in the various type of ginseng samples could be analyzed simultaneously and expected to be suitable for quality control of ginseng products.

The purpose of this study was to evaluate the quality of castella added with different concentrations (0%, 5%, 10%, and 15%) of Panax ginseng sprout powder. The specific gravity of castella made with 15% ginseng sprout powder was the highest (0.65), and baking loss rate was highest well. However, the height and weight of castella were highest in the control. The pH of castella decreased with increasing levels of Panax ginseng sprout powder, whereas sugar content of castella did not show significant differences. The Hunter L, a, and b values of crust decreased as the concentration of Panax ginseng sprout powder increased. The Hunter L and a values of crumb decreased as the concentration of ginseng sprout powder increased, whereas b values of crumb increased. The gumminess and chewiness of castella increased by addition of Panax ginseng sprout powder, whereas cohesiveness of castella decreased. The hardness and springiness of castella did not show significant differences. In the sensory evaluation, crust color, crumb color, aroma and moistness did not show significant differences among samples while sweet taste, and chewiness were highest in the control group. The overall acceptability of castella added with 5% Panax ginseng sprout powder was the highest. Therefore, the results suggest that castella added with 5% ginseng sprout powder could be helpful for improving physical quality and taste.
