  • This study was performed to investigate the antioxidative and sensory properties of Allium hookeri fermented by Leuconostoc mesenteroides in pork patties. The patties were divided into three groups: CON, with no Allium hookeri powder; AH, containing 1% Allium hookeri powder; and FAH, containing 1% fermented Allium hookeri powder. Allium hookeri fermented by L. mesenteroides significantly increased the radical scavenging activities of 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) compared to that in normal Allium hookeri (p<0.05). The cooking loss and expressible drip for FAH were significantly lower than the corresponding values of other groups (p<0.05). The pH and 2-thiobarbituric acid reactive substances value of the FAH were significantly lower than that of CON on the day 3 and 7 (p<0.05). In the texture analysis (TPA), FAH showed significantly decreased hardness and chewiness grades compared to the CON and AH (p<0.05). FAH had significantly higher color, flavor, tenderness, juiciness, and overall acceptability scores than the CON and AH (p<0.05). This study suggests that the adding fermented Allium hookeri effectively improved the quality characteristic of the food.

  • The effect of the addition of Allium hookeri on the quality of fermented sausage made with meat from sulfur fed pigs was examined, throughout a 60 d ripening period. There were two treatments in animal management: normal feed fed pigs, and sulfur fed pigs given 0.3% sulfur mixed normal feed. Fermented sausage manufactured with meat from normal feed fed pigs, and with meat from sulfur fed pigs, and 1% A. hookeri-containing fermented sausage processed with meat from sulfur fed pigs, were determined at 1 d, 15 d, 30 d, and 60 d. The meat qualities in fermented sausage were measured by DPPH radical scavenging activity (DPPH), $ABTS^+$ radical scavenging activity ($ABTS^+$), total phenolic acids, and total flavonoid contents. Fermented sausage made from pigs that had been fed with 0.3% sulfur was protected from oxidation by reduced free radical, as shown by the significant increase in DPPH and $ABTS^+$ values, compared with fermented sausage made from normal feed fed pigs (p<0.05). A. hookeri-added fermented sausage with sulfur fed pork was shown to increase the values in DPPH, $ABTS^+$, total phenolic acid, and total flavonoid contents, by comparison with both the control sausage, and sausage with sulfur fed pork, at 60 d. These results suggest that A. hookeri in meat from sulfur fed pigs could be a source of natural addition, to increase quality in the food industry.

  • Allium hookeri, a member of the onion family, has long been mainly cultivated for food and medicinal use in Southeast Asian countries, owing to its various biological properties. However, no studies of the anti-oxidative effects of fermented A. hookeri root extracts have been conducted to date. Therefore, this study investigated the effect of different starter cultures on the antioxidant activities of hot water extract of A. hookeri root by using the following five strains: Lactobacillus acidophilus, Bifidobacterum longum, Enterococcus faecium, Streptococcus thermophilus, and Saccharomyces cerevisiae. DPPH and ABTS radical scavenging activity, total phenolic acid contents, and total antioxidant capacity were higher in the hot water extract of A. hookeri root fermented with starter cultures than those of A. hookeri root. Among hot water extract of A. hookeri root fermented with starter cultures, fementing with S. cerevisiae showed the highest antioxidant activities. The results of this study provide new evidence of the anti-oxidative properties of A. hookeri root with starter cultures, indicating that it may be highly valuable as a natural product owing to its high-quality functional components.

  • Allium hookeri is a plant species native to India, Sri Lanka, Myanmar, and China. The plant is widely cultivated in Korea lately as a medicinal food item. This study was conducted to evaluate the effects of Allium hookeri (A. hookeri) on lipid metabolism in Type II diabetic mice (n=8/group, 5 groups). High fat diets with dextrin as a positive control (Dex), leaf (AL), root (AR), and fermented root (FAR) at 3% of diet were fed to all experimental mouse, respectively for 8 weeks. Body weight gain, liver and epididymal fat weights, and excreted fecal lipid levels were measured. Serum and hepatic lipid profiles were analyzed, and fat accumulation in liver was evaluated. In this study, body weight gain and epididymal fat weight were lower in the FAR group, while serum HDL-cholesterol level and excreted fecal total lipid and triglyceride levels were higher in AL or FAR groups. These results suggest that A. hookeri, specially fermented root can be a useful food item to control lipid metabolism in diabetic mice.

  • Hot water extraction concentrate was prepared from Alliun hookeri root (AHR) to evaluate its applicability to yogurt. The highest antioxidant activity of hot water concentrates was obtained under extraction conditions of 4 hr at $95^{\circ}C$. Antioxidant activities measured by DPPH radical assay, ABTS radical cation assay, reducing power, and cheating activity were highly correlated with total phenolic (89.51 mg/g) and total flavonoid (52.71 mg/g) contents, with R values of 0.94 and 0.96, respectively. Yogurt was fermented with a commercial lactic acid bacteria mixed strain (Yo-mix$^{TM}$ 305) for 10 hr at $42^{\circ}C$ after addition of 0~10% (w/w) hot water concentrates from AHR to yogurt base. As fermentation proceeded, pH and $^{\circ}Brix$ of yogurt decreased from 6.57~6.60 to 4.34~4.51 and from 8.10~8.90% to 4.60~5.25%, respectively, whereas titrate acidity, viscosity, and viable cell numbers increased from 0.22~0.23% to 1.01~1.10%, from $0mPa{\cdot}s$ to $202.55{\sim}290.50mPa{\cdot}s$, and from 6.40~6.80 log CFU/mL to 8.60~9.20 log CFU/mL, respectively. There was no significant difference in any sensory attribute between the control and 2.5% addition group, suggesting that 2.5% hot water concentrate from AHR could be used to manufacture yogurt.
