  • This study was conducted to examine the sensory attributes, gingerol content and volatile components of ginger paste resulting from microbial fermentation. In the ginger samples, a total of eighteen attributes were determined to characterize the sensory attributes from descriptive analysis. These eighteen attributes consisted of the following: one appearance, eight odor/aroma, eight taste, and one aftertaste attribute. The ginger fermented using Lactobacillus plantarum produced a ginger aroma and putrid taste, whereas the sample fermented with Lactobacillus brevis showed a decreased ginger aroma and taste, and generated a lemon flavor. A total gingerol content of fresh and fermented ginger was 100.19 mg% and 89.55 mg%, respectively. Sixty-one volatile components in the fresh and fermented ginger were identified, and constituted eight kinds of monoterpenes, twenty-one kinds of sesquiterpenes, eight kinds of oxygenated monoterpenes and nine kinds of oxygenated sesquiterpenes. The most abundant volatile component identified in the fresh ginger was $\alpha$-gingerberine (26.52%), whereas fermented ginger was increased in its alcohol components.

  • This study was performed to investigate the effect of promoting gastrointestinal function and inhibiting of decreasing body temperature of ginger extract(Zingiber officinale) in rats. In order to elucidate the gastrointestinal function and inhibiting effect of body temperature of native ginger and improved ginger, water extracts of ginger were orally administrated into rats. The results are as follows: The gastrointestinal transit time was significantly decreased in native ginger(7.66hrs) and improved ginger(7.72hrs) extract administrated groups compare to control group(8.44hrs). The mean red faecal weight was increased in native ginger(30.6%) and improved ginger(31.1%) extract administrated groups compare to control group(24.9%) for 24hrs. Inhibiting effect of decreasing body temperature induced by serotonin was increased in native ginger($1.116^{\circ}C$) and improved ginger($1.416^{\circ}C$) extract administrated groups compare to positive control group($0.384^{\circ}C$) during 40 minutes. Gastrin and CGRP immunoreactive density was more strongly expressed in native ginger and improved ginger extract administrated groups compare to control group. Serotonin immunoreactive density was more weakly expressed in native ginger and improved ginger extract administrated groups compare to control group. These results suggest that ginger extracts may enhance physiological activity such as gastrointestinal motility, protection of mucosa and gastric acid secretion in gastrointestinal tracts, and inhibits decreasing body temperature

  • In this study, when we reflect the preference of consumers who wish to receive their health through natural materials, and whose purpose is to receive good quality and good tasting cookies made from ginger. After 0%, 2%, 4%, 6%, 8% of flour was replaced by ginger powder for making cookies, a comparative analysis of quality characteristics and QDA was completed. Adding ginger powder caused a decrease in the density of the cookie dough, moisture content, loss rate and leavening rate of cookie (p<0.05), but the hardness of the ginger cookie increased. As a result of the description analysis of adding ginger powder, adding ginger powder increases, cookie color, crispiness, acid taste, flavor, and an after taste, but not the sweetness of the cookie. In terms of cookie color, crispiness, taste, flavor and overall acceptability, adding 4% ginger powder received high reviews. Also as a result of measuring DPPH radical elimination, ginger powder shows to have good antioxidant activity. So their anti-cancer activity is better than cookies without ginger powder. Therefore, we expect that we can fulfill the overall acceptability.

  • Sliced ginger samples were dried using 30, 50, and 80% maltodextrin, respectively, as a dehydrating agent. The moisture content of the maltodextrin-treated ginger decreased with increasing concentrations of maltodextrin. The dehydrated ginger was compared with hot air-dried and freeze-dried ginger samples in terms of rehydration ratio, gingerol content, color, and sensory characteristics. The rehydration ratio of the maltodextrin-treated ginger was superior to those of the hot-air dried or freeze-dried ginger. In addition, the maltodextrin-treated ginger had the highest content of 6-gingerol among the samples. Color as well as sensory scores for odor, texture, appearance, and overall acceptance were greater for the maltodextrin-treated ginger compared to the hot-air dried or freeze-dried ginger. These results indicate that drying ginger with maltodextrin is very efficient because good rehydration capacity is retained and minimal cell destruction can be achieved.

  • This study investigated the quality characteristics of apple jam added with ginger. The apple jam was prepared with apples, sugar, lemon juice and various amounts (0, 2, 4, 6, 8%) of ginger. Increasing the amount of ginger decreased moisture contents and sugar content of the jam, whereas the pH gradually increased. In addition, with increased amount of ginger, the lightness(L) and yellowness(b) significantly decreased, while redness(a) gradually decreased. There wasn't any significant difference in the samples with up to 4% ginger(p<0.05). In the texture profile analysis, hardness and adhesiveness increased significantly with increased amount of ginger. When more amount of ginger was added, cohesiveness increased with no significant difference based on the amount of ginger. With increased amount of ginger, springiness and chewiness gradually increased. The results of the sensory evaluation show that the apple jam added with 4% ginger got the highest overall-acceptability scores. In conclusion, it is possible to enhance the quality and acceptability of apple jam by adding 4% ginger.
