  • Sorbic acid is one of preservatives that is mostly used in general food. This study was carried out to measure the amount of the sorbic acid in cooked meat produced from meat processing plants in Gyeongbuk province. One hundred and fifty-three samples of cooked meat(42 spices added meats, 56 grinding cooked meats, 2 bacons, 5 jerked meats, 18 sausages, 30 hams) were collected from meat processing plants and analyzed for the concentration of preservative sorbic acid and its salts by using of high performance liquid chromatography(HPLC). Sorbic acid was not detected in spices added meats, grinding cooked meats, bacons, and jerked meats except on ham and sausage. But the concentration range of sorbic acid in sausage was 0.00~1.31g/kg, average 0.44g/kg, and in ham was 0.00~1.31g/kg, average 0.329/kg. There was no sample that sorbate concentration exceeded the legal permitted level 2.0g/kg in cooked meat.

  • The study of health promoting and disease preventing compounds in food or by themselves, so called nutraceuticals or functional foods, has become a major field of research in food science. Natural flavor compounds are usually present in food, essential oils, spices, and herbs. These compounds can produce aroma, not only by themselves, but also in combination with other compounds. Today, however, greater interest is being paid to the health promoting properties of natural flavor substances rather than their flavoring properties. In fact, a number of naturally occurring flavor compounds that possess health promoting and disease preventing properties have been extensively studied and identified. The beneficial properties of natural volatile flavor compounds as well as non-volatile substances in spices and herbs discussed in this review include antioxidant, anticarcinogenic, anti-inflammatory, and immune enhancing activities.

  • Several spices in the range of $1{\sim}3%\;(w/w)$ were added during Kimchi preparation in order to investigate their effects on the chemical changes and fermentation rate. The results showed that addition of red pepper powder by 2% slightly increased the fermentation rate reaching max. value after 36 hours, while 3% addition gradually increased its rate without max. point. Generally higher reducing sugar and acidity were measured for red pepper added Kimchi. The fermentation rate and its max. point were significantly increased as more garlic added and the max. value of ascorbic acid produced was also increased. Little effects were found for Welsh onion and ginger on Kimchi fermentation.

  • This study was conducted to understand the inhibitory garlic and ginger against the growth of food born pathogenic bacteria. Juice was prepared from the raw spices by using an electric homogenizer and membrane filter. Dry-powdered spices were treated with double distilled water and 70% ethanol to extract the antibacterial substances, respectively. Growth inhibitory effects of juice and extracts of the spices were monitored by using bacterial strains such as B. subtilis, L. moncytogenes, S. aureus,E. coli O157 : H7, P. aeruginosa, and S. typhimurium. On a solid medium where E. coli and S. aureus cells were grown, ginger juice formed inhibitory zone at the concentrations of 2-10% by paper disc test. The Bone formed by ginger juice was wider and more transparent than that formed by garlic juice on the same concentration.1. monocytogenes and B. subtilis were more sensitive to garlic juice than others, and stopped growing at 2% garlic juice. Ginger juice showed the growth inhibition by 30-50% at 1.0% concentration. On the contrast, P. aeruginosa which resisted to the garlic juice was the most sensitive to ginger juice. Water extract of garlic was not effective to inhibit the bacterial growth, while 2% ginger extract completely inhibited the growth of E. coli and S. aureus. Alcohol extract of ginger inhibited the growth of bacteria at the concentration of 0.3%. This growth inhibition is almost 10 times lower than that of the garlic extract. It was clear that ginger had more potential than garlic as an inhibitor to control the growth of the indicator organisms.

  • In order to investigate the content of preservative components occurred naturally in foods, the content of benzoic acid and sorbic acid in 48 kinds of plants which used as commercial teas or spices was determined according to the method of 'Korean Food Code' and analyzed with a gas chromatograph. The recoveries of the benzoic and sorbic acid were 82.5% and 94.5%, respectively. The naturally occurring benzoic acid was less than 50 ppm in most of the plants used as commercial teas. The content of benzoic arid in spices and the content of sorbic acid in teas or spices were less than 10 ppm. The average contents of benzoic acid and sorbic acid in edible part of each plant were as followed ; leaf 12.5 ppm and 8.1 ppm, root 16.8 ppm and 3.7 ppm, seed 9.8 ppm and 2.3 ppm, fruit 33.8 ppm and 1.2 ppm, fungus 18.3 ppm and 14.6 ppm, respectively. The contents of benzoic acid and sorbic acid in several plants used at teas or spices extended over a wide range.

  • For the purpose of developing natural antioxidant, the antioxidative and antimicrobial activities of phenolics isolated from spices were determined. The total phenolics contents of spices were more than 20 mg/g in water and 60% ethanol extracts of all spice, oregano and sage. Electron donating ability assay showed high inhibition rate in water extracts of all spice, nutmeg, white pepper, oregano and sage and 60% ethanol extracts of oregano and nutmeg. Antioxidant protection factor (PF) was higher than 1.2 in 60% ethanol extracts of sage, all spice and oregano and water extracts of sage. The 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical decolorization (ABTS) was inhibited by more than 90% by water and 60% ethanol extracts of all spice and oregano. TBARS (thiobarbituric acid reactive substances) were $0.7{\mu}M$ in the control and $0.2{\mu}M$ in water and 60% ethanol extracts the each spices. The water extracts of each spices did not have antimicrobial activity against H. pylori; however, the 60% ethanol extracts from oregano revealed the high antimicrobial activity as clear zone of 10 mm and inhibition rate of 77.2% with $200{\mu}g/mL$ of phenolics content. The result suggests that spices extract may be useful as potential sources of anti-Helicobacter pylori, antioxidant.

  • Photostimulated luminescence(PSL)-Thermoluminescence(TL) combined analysis was applied to detect whether composite seasoning products and spices were irradiated or not. Samples were irradiated with $^{60}Co$ at $0{\sim}7$ kGy. A total of 12 different samples(6 of composite seasoning products and 6 of spices) was examined. Depending on the PSL results, TL analysis was performed. In case of both PSL positive(${\geq}5,000$ counts) and intermediate($700{\sim}5000$ counts), TL analysis had to be performed to confirm the result of PSL. Using TL, the shape of the glow curve(Glow 1) made it possible to identify the irradiated samples. In addition, The TL glow ratio(Glow 1/Glow 2) obtained by normalization was less than 0.1 for the non-irradiated samples and ${\geq}0.29$ for irradiated ones, respectively.
