Korean Journal of Food Preservation, volume 14, issue 5, 2007, Pages 445~450
This studies were engaged to investigate the potential us of Curcuma aromatica Salab. as a food ingredients. The antimicrobial activity of Curcuma aromatica Salab. extract (CE) and effect on shelf life of the cooked rice were examined. The antimicrobial activity of CE showed apparently against Bacillus cereus, B. subtilis and B. megaterium. The minimum inhibitory concentration (MIC) of CE was 0.15% for B. cereus md 0.2% for B. subtilis and B. megaterium. The antimicrobial activity of CE remained relatively high after heat treatments(30 min at 80 and
, 15 min at
). The shelf life of cooked rice containing above 0.05% CE increased more 1 or 2 days than that of control at
, The texture of cooked rice was improved by addition of above 0.01% CE. The sensory quality of cooked rice with CE did not show significant difference between 0.00% and 0.05% in taste and overall acceptability but decreased above 0.10% in taste, color, flavor and overall acceptability.

Han, Jae-Yoon ; Kim, Mi-Hwan ; Park, Jong-Hwan ; Kim, Seok-Joong ; Park, Hee-Yong ; Koksel, Hamit ; Ryu, Gi-Hyung ;
Korean Journal of Food Preservation, volume 14, issue 5, 2007, Pages 451~456
The vitamin C content in extruded comstarch matrix was shown to depend on extrusion process variables (barrel temperature and water content), the packaging method, and the storage period. In addition, loss rates of vitamin C under different processing conditions were calculated. Extrusion process variable were barrel temperature (
), and water content (25% 30% both w/w). The vitamin C content decreased as barrel temperature increased from
and water content increased from 25% to 30% when either LDPE plastic film packaging or ON film vacuum packaging were employed. As barrel temperature and water content increased, vitamin C decreased in comstarch packed in either LDPE film or ON film. As temperature increased, vitamin C loss rate increased under both packaging conditions, but the loss tate was only 50% of the LDPE film packaging rate when ON film vacuum packaging was used. In conclusion, the higher the temperature, and the greater the water content, the less vitamin C was inactivated during extrusion cooking, although the loss rah of vitamin C became faster as temperature and water content rose. In conclusion, extrusion process could be applied for making vitamin C matrix to extend vitamin C preservation.

Park, Hyung-Woo ; Lee, Seon-Ah ; Kim, Yoon-Ho ; Kim, Yu-Mi ; Cha, Hwan-Soo ; Park, Jong-Dae ;
Korean Journal of Food Preservation, volume 14, issue 5, 2007, Pages 457~461
We investigated the effects of both
treatment and modified atmosphere packaging (MAP) (compared with non-packaging on 'Fuji' apples from the Young-Joo region of Korea. Apples were dined into 5% (w/v)
solution for 15 min and then packaged with or without LDPE film (thickness: 0.025 mm) before cold storage at
. Weight loss of applies in film packaging was lower than that of non-packaging applies, and the apple firmness resulting from
treatment and MAP was better than that of apples receiving control treatment. Also,
treatment and MAP resulted in improvements in titratable acidity, soluble solid content (SSC), and decay rate compared to control treatments. However, no significant differences in vitamin C content were found amongst apples receiving various treatment. the results suggest that a combination of postharvest calcium dipping and plastic film packaging may effectively preserve 'Fuji' apples, and that the combined treatment are better than either individual treatment.

Kim, Jong-Hoon ; Jeong, Jin-Woung ; Kweon, Ki-Hyun ;
Korean Journal of Food Preservation, volume 14, issue 5, 2007, Pages 462~468
In this study, the quality effect of soaking in alum water, soaking in electrolyzed oxidizing water, and freezing during storage, on peeled chestnuts, were analyzed. When soaked in 0.1% (w/v) alum water, peeled chestnuts showed good characteristics in terms of weight loss, decomposition, and color preservation. However, texture and taste qualities rapidly decreased with increases in storage time. When soaked in twice their own weight of electrolyzed oxidizing water(pH 2.61, ORP 1,142 mV) for 10 min, the samples were preserved in an optimally edible condition. When frozen at
for 5 min, the samples were suitable for use as material for processed chestnut produce, as was also the case when pretreatment with electrolyzed oxidizing water was employed.

This study was conducted to evaluate the combined effect of gamma irradiation and silk peptide on the radiosensitivity of bacteria and the storage stability of ready-to-eat hamburger patty. The
values obtained for Escherichia coli, Listeria ivanovii, Salmonella typhimurium and Clostridium sporogenes by gamma irradiation were 0.25, 0.50, 0.55 and 1.35 kGy, respectively. The inactivation rate of S. typhimurium (
) inoculated into hamburger patty with 5%(w/w) silk peptide was reduced 6% compared with the control
). In acceleration storage at
, microorganisms were not observed in samples irradiated with 7 kGy or 10 kGy during storage. However the irradiation at 5 kGy was insufficient to sterilize the contaminated microorganisms in hamburger patty regardless of the addition of silk peptide (5%). These results indicate that the combined treatment of gamma-irradiation and silk peptide admixture could be helpful to ensure storage stability of ready-to-eat hamburger patty, by controlling the preliminary microbial load.

In order to develop a new rice bran danmooji, changes in physicochemical characteristics and texture of danmooji treated with rice bran, Stevia rebaudiana Bertoni leaf powder, succinic acid, or yeast extract were investigated during salting for 90 days. The PH of rice bran danmooji decreased from PH6.41 initially to pH 4.09 (control group), pH 4.10 (S. rebaudiana treatment S1), pH 3.84 (S. rebaudiana + succinic acid treatment S2), and pH 3.90 (S. rebaudiana+succinic acid+yeast extract treatment S3) after 90 days of salting. At this time, the salinities of rice bran danmooji of the S1, S52, and S3 groups were 2.32%, 1.94% and 2.15% respectively. The hardness of all groups decreased rapidly in the first 30 days of salting, and thereafter showed no changes. After 90 days of salting, the hardness of all groups was
with no significant differences between groups. Redness, the a value, of the S2 and S3 groups treated with succinic acid, was lower than that of S3, whereas yellowness, the b value, of S3 treated with succinic acid and yeast extract was the highest of the three groups. Sensory evaluation of rice bran danmooji after 90 days of salting resulted in S3 attaining the highest scores for flavor, taste, texture, and overall acceptability. These results indicate nut high-quality rice bran danmooji may be prepared by addition of S. rebaudiana leaf powder, succinic acid and yeast extract to rice bran.
