  • To investigate the effect of sugar and drying method on quality and storage characteristics of beef jerky, storage, textural and sensory characteristics were examined. Water activity was decreased as storage time was prolonged and the honey and rice syrup-added natural dried samples(N-H, N-R) were recorded the lowest value, 0.71 at five weeks of storage. During the storage period, pH values of all the samples were decreased and honey-added and heated air dried beef jerky(H-H) had the lowest pH value, 5.22. L, a, b values had a tendency to decrease, during the storage period. During the storage period, TBA values of all samples showed increasing tendency. Sugarsyrup-added samples(N-S, H-S, S-S$\^$*/) had the lowest TBA value, and those of honey-added samples(N-H, H-H, S-H$\^$**/) were highest, regardless of drying method. Total plate counts of bacteria and the number of lactic acid bacteria were increased as storage time was prolonged. Sugar syrup-added and heated air dried beef jerky(H-S) had the lowest in total plate counts of bacteria and the number of lactic acid bacteria, at five weeks of storage. Textural properties value of all samples were increased as storage time was longer. Honey-added samples showed the higest springness and cohesiveness value and sugarsyrup-added and natural dried sample showed the highest value in chewiness, gummness and hardness.

  • The sugers and free amino acids of honey(Western and Domestic honey) and the changes of diastase activity during storage at various temperatures and HMF were studied. The average content of sugers in the western honey was 40.20% of fructose, 32.43% of glucose and 1.0% of sucrose. The average ratio of fructose to glucose was 1.24. In the case of the domestic honey, average content of sugers was 37.37% of fructose, 31.92% of glucose and 0.74% of sucrose and the average ratio of fructose to glucose was 1.19. Of the 16 amino acids detected, proline was the most predominant free amino acid in all of the honey studied, representing 39.59 to 46.86% of total free amino acids. Diastase activity of honey during the storage at $50^{\circ}C$ was rapidly decreased, but it was notably changed during storage at low temperature ($4^{\circ}C$) and room temperature ($20^{\circ}C$). The accumlated content of HMF were 0.12 to 0.47mg% during storage at 80 days at $20^{\circ}C$ and 5.35 to 8.71mg% after 3 weeks storage at $50^{\circ}C$.

  • Various records on health, food and treatment are written in ancient documents of Korea such as old recipe books, Korean medical books and history books, through these records, the principle of Sikchi can be discovered. Sikchi includes the meaning of medicine and food work on the same principle, and it is not only as traditional knowledge but also affecting modern food culture. Based on this principle of Sikchi, this study tried to lay a foundation that can be used as a modern health food material through scientific verification of foods recorded in the ancient literature. For this purpose, Omigalsu, a traditional drink made from omija, soybean, and honey, which is related to blood glucose control, which is one of the representative metabolic diseases of modern people, was selected as the subject of this study. In order to compensate for the agglomeration of beverages caused by honey or the rise in postprandial blood glucose, which occurs when the traditional Omigalsu recorded in the ancient literature is reproduced, the raw material that can be substituted for honey was discovered. The health promotion and quality improvement effects of newly prepared Omigalsu using honey substitutive raw material were confirmed through a comparative test with traditional Omigalsu. Based on this study, through scientific research using the principle of Sikchi, we intend to lay a foundation that can be used as various contents in the medical and food fields such as food bio and healthcare in modern society.

  • The traditional Korean drink "Jehotang", which is one of the most commonly prescribed drugs for treatment of the heat stroke accompanied by high fever, severe sweat and thirst, it is effective far quenching thirst strengthening the stomach, stopping diarrhea and regulating intestinal function. It is also known to play a role in activating the growth of useful microbes in the intestine and in multiplying intestinal immune cells. Thus, this study investigated all aspects of the drink in an effort to develop a new functional beverage. In the course of this study, the analytical research into the literature concerning Jehotang an error in the secrets of preparing the drink. The Japanese apricot, which was given the botanical name, "Prunusmume", should only be used with the flesh (scientifically referred to as "Fructusmume"), which is fumigated with straw fire before drying. and the seed should be thrown away. The honey should only be used after it is heated with a gentle fire, before removing the white foam that farms on its surface to make the "Yeonmil". Two kinds of cooking processes were found in the ancient literature. One procedure boiling down the powered Fructus mume mixed with the Yeonmil, while the other procedure involved preparing the Fructus mume's water by adding water to it and blending the water with the Yeonmil and the rest of the raw ingredient before boiling them down. The current procedure, in which the cooking is done in a double boiler, has been widely adopted to its simplicity. The finished Jehotang is put in porcelain, kept at room temperature, and consumed after mixing with cold water.

  • This study analyzed the total polyphenol (TP), total flavonoid (TF), and protein content, the Absorbance at 400 nm (A400), and the antioxidant and hemolytic activities of 150 Korean honey products, including 41 chestnut (CH), 42 acacia (AH), 62 multi-floral (MH), and five Styrax japonica (TH) varieties. Our results showed that the components and antioxidant activities of honey are dependent on botanical origin rather than farming area or farmer. CH showed the highest levels of TP (88.6±29.8 mg/100 g) and TF (1.20±0.82 mg/100 g), whereas TH had the highest protein (21.5±5.1 mg/100 g). A400 was the highest in CH (0.161±0.044). All of the honey products exhibited negligible hemolytic activity against human red blood cells up to 1 mg/ml. Potent radical scavenging activities for 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2,2-azobis(3-ethylbenzothiazoline-6- sulfonate) (ABTS), nitrite and reducing power were also observed in CH. Correlation coefficients (CCs) between analysis parameters were calculated and the highest was identified between TP and ABTS scavenging activity (0.726). The CCs between A400 and TP and A400 and ABTS scavenging activity were 0.644 and 0.661, respectively, suggesting that A400 could be used as a quality indicator for the polyphenol content and antioxidant activity of particular honeys. Future research on polyphenol by flower origin and the identification of compounds for A400 is necessary.
