  • This study was conducted to evaluate the growth of lactic acid bacteria and quality characteristics of Baechu kimchi prepared with four types of salt (Solar salt, Flower salt, Hanju salt, and Roasted salt) at two different concentrations (10, 15%) during storage. The quality characteristics of kimchi were examined by investigating acid production, growth of lactic acid bacteria, sensory properties, salinity, texture, and color characteristics. Baechu kimchi was fermented for 18 days at $10^{\circ}C$. The pH and total acidity did not change during storage according to type and concentration of salt. Growth of lactic acid bacteria was not affected by type of salt, whereas it was inhibited at 15% salt concentration after 9 days of fermentation. In the quantitative descriptive analysis of sensory properties, kimchi prepared with 10% salt showed significantly higher scores in term of overall acceptability (p<0.05). Meanwhile, there was no significant difference by type of salt. For texture characteristics, hardness of kimchi prepared with 10% salt was significantly higher than that with 20% salt. For color characteristics, L value (brightness) and b values (yellowness) of kimchi prepared with 10% salt increased during fermentation, whereas a value (redness) did not change by type and concentration of salt. The results of this study show that there were no considerable differences in quality characteristics of Baechu kimchi prepared with various types and concentrations of salt. However, Solar salt resulted in more favorable sensory properties and salinity of kimchi than any other types. Further, kimchi prepared with 10% salt showed significantly higher scores in terms of overall acceptability, growth of lactic acid bacteria, salinity, texture, and color characteristics.

  • The aim of this study was to evaluate the effect of kimchi powder levels (0, 1, 2, and 3%) and pork skin (5%) on the quality characteristics of liver sausages. The additions of the kimchi powder and pork skin improved the color, cooking yield, and sensory properties of the sausages. The addition of the pork skin and increasing concentrations of the kimchi powder significantly increased cooking yields. The moisture and protein contents of the sausages made with kimchi powder and pork skin were higher than those of the control (p<0.05). Due to the low pH of the kimchi powder, the pH values of the batter and sausages with added kimchi powder were lower than those of the treatment without kimchi powder (p<0.05). The control had the lowest hardness, gumminess, and chewiness values (p<0.05). For the sensory attributes of the samples, color, flavor, juiciness, and overall acceptability were higher in the treatments made with kimchi powder than in the treatments without kimchi powder, in which the treatment with 2% kimchi powder had the highest overall acceptability (p<0.05). In conclusion, the additions of kimchi powder and pork skin improved the quality characteristics of liver sausages.

  • Purpose: The purpose of this study was to evaluate the folate contents and quality characteristics of commercial and fermented Kimchi and compare the correlation between folic acid and quality characteristics. Methods: The contents of total folate and quality characteristics were evaluated in 10 kinds of industrial and local Kimchi and nine kinds of other commonly consumed Kimchi. Changes in folate content and quality characteristics of Kimchi during 14 days of fermentation at $15^{\circ}C$ were compared. Results: Chungnam (L4) Kimchi had the lowest pH of 4.62, and acidity (0.57%) and salinity (3.26%) were highest compared to other areas. The content of total folate of D company (A) was the highest at $73.66{\mu}g/100g$. The content of total folate was significantly higher than those of Sesame leaf Kimchi (O9) and Young leafy radish Kimchi (O5) containing 65.77 and $62.82{\mu}g/100g$, respectively. The pH of fermented Kimchi decreased from 6.09 to 4.11 (p<0.05), and the acidity significantly increased (p<0.001) to 0.32-0.66%. Reducing sugar content decreased rapidly by 4 days and then slowly decreased (p<0.001). Total bacteria and lactic acid bacteria counts significantly increased (p<0.05) with fermentation period. Content of total folate was highest at $69.82{\mu}g/100g$ and $68.16{\mu}g/100g$ on days 0 and 2 of fermentation, after which it decreased to 77.6% at $15.61{\mu}g/100g$ on day 10 of fermentation. Conclusion: As a result, there was no definite trend regarding folate content in commercial Kimchi and other Kimchi. Young leafy radish, Chives, and Welsh onion Kimchi, which are rich in green leaves, are excellent folate source foods. The highest folate content of fermented Kimchi was identified on day 2 of fermentation. Therefore, it is recommended to use raw or immature Kimchi when using Kimchi as a folate source food.

  • Acetic acid solution containing calcium (AC) was added to kimchi seasonings by 10% and 205, and heat treatment at 70$\^{C}$ for 15 min was also tried, respectively. Kimchi with treated seasonings was investigated for the quality during fermentation at 10$\^{C}$. Heat treatment with 20% AC showed a retarded decrease pH than others on 10 days, but there was no great difference after 14 days. Higher titratable acidity was revealed in kimchi with AC during the fermentation. Total microbial lead and lactic acid bacterial count were generally lower in kimchi with AC. Reducing sugar content was maximum for all samples on 5 days, and then decreased thereafter. Redness of control kimchi was steadily increased during fermentation, but was lower than those of other treatments.

  • Colour and texture are the most difficult quality aspects of Kimchi to maintain during storage. Therefore, this study investigated how to maintain superior quality Kimchi during fermentation without changes in color and texture. By examining differences between samples covered with vinyl(A group) and not covered with vinyl(B group) and assessing pH, total acidity, total viable cell count, total lactic acid bacteria cell count and sensory characteristics. The results are indicated that pH, total acidity, total viable cell and total lactic acid bacteria were similar between group A and B. Group A showed higher sensory score for colour, taste, texture and acceptability than group B(p<0.001). Covering the Kimchi with vinyl appeared to have a similar effect as when Kimchi is kept in a Kimchi-pot under stones or the outer leaves of vegetables making it possible to maintain good color and texture during storage. In conclusion, even though, it is not practical to use Kimchi-pots within urban settings today, vinyl coverings may offer the same effects.

  • This research was performed to investigate the potential use of Capsella bursa-pastoris (L.) as an ingredient to improve the biological function and flavor of kimchi. The quality characteristics were studied for kimchi with or without Capsella bursa-pastoris (L.) Medicus (CBM kimchi) during fermentation for 25 days at $10^{\circ}C$. The pH changes of CBM kimchi were slower than those of control but did not show any significant difference after addition of Capsella bursa-pastoris (L.) Medicus during fermentation. The titratable acidity of CBM kimchi was higher than that of control. The log number of total bacteria was lower about 1.5 $log_{10}$ cycle in CBM kimchi than in control during fermentation. However, lactic acid bacteria did not show significant difference between CMB kimchi and control. Sensory qualities of kimchi such as color, taste, flavor and overall acceptability were significantly improved by addition of 3% Capsella bursa-pastoris (L.) Medicus(p<0.05).
