The purpose of this study was to evaluate the intake of antioxidant vitamins and plasma concentrations of those in 60 maternal-infant pairs (30 in normal term delivery group, NT; 30 in preform delivery group, PT). We also investigated the relationship between vitamin levels of maternal-umbilical cord plasma and pregnancy outcome. Mean energy intakes of NT and PT pregnant women were 93.2% and 85.4%, and their protein intakes were 113.3% and 110.9% of the recommended dietary allowance (RDA), respectively. While vitamin A intakes were only 51.2% and 39.6% of the RDA in NT and PT pregnant women. The vitamin E intake was about 50% of the RDA (NT 6.27 mg, PT 7.78 mg). The levels of retinol in maternal plasma of NT and PT were $1.51\mumol/\ell\;and\;1.43\mumol/\ell$, respectively. The retinol levels in umbilical cord plasma in NT and PT were $0.72\mumol/\ell\;and\;0.61\mumol/\ell$, respectively. The level of $\beta-carotene$in maternal plasma of NT was 0.49 $\mu$mol/$\ell$, significantly (p ＜ 0.01) higher than that of PT ($0.31\mumol/\ell$).The $\beta-carotene$ of umbilical cord plasma of NT and PT were $0.702\mumol/\ell\;and\;0.01\mumol/\ell$, respectively. The plasma $\alpha$-tocopherol of maternal of NT and PT were $0.72\mumol/\ell\;and\;0.01\mumol/\ell\;29.51 /mumol/\ell\; and 27.17\mumol/\ell,\;respectively.\; The $\alpha$-tocopherol of umbilical cord plasma of NT and PT were $4.16\mumol/\ell\;and\;3.80\mumol/\ell$, respectively. The antioxidant vitamin levels (retinol, $\beta-carotene,\;and\;\alpha$-tocopherol) in maternal plasma were significantly higher (p＜0.0001) than those in umbilical cord plasma. However, there was no correlation between the vitamin levels in maternal plasma and those in umbilical cord plasma. The maternal plasma $\beta$-carotene level showed a positive correlation to gestational age. Also Apgar score at 1 min produced a positive correlation to maternal plasma $\beta$-carotene level.

High-performance liquid chromatography (HPLC) was applied to determine the carotenoid composition of carrots during storage and cooking. Analyses were conducted immediately after harvest and 1, 2, 4, and 8 weeks after harvest. During the course of the storage, the carotenoid levels generally decreased, and this decrease was found to be greater during the first week for $\beta$-carotene (all-trans-$\beta$-carotene) and lutein, and during the second week for $\alpha$-carotene. Additionally, the amount of the $\alpha-$ and $\beta$-carotenes in carrot leaves changed slightly within the first 2 weeks of harvest when stored at $4^{\circ}C$. Specifically, the level of lutein, the main component of carrot leaves, increased from 233.8$\pm$11.7 to $346.2\pm26.7{\mu}g$/g DW during the first 2 weeks. In addition, the change in carotenoid contents was observed during the home-processing of one Korean cultivar. Carrots fried in oil showed the highest amount of $\beta$-carotene ($164.3\pm6.6{\mu}g$/g DW) and $\alpha$-carotene ($50.1\pm0.4{\mu}g$/g DW), while carrots that were prepared by sauteing, pressure-cooking in water and microwaving had the second highest levels. The greatest loss of in carotenoids occurred in response to boiling in water containing 1% NaCl, braising and baking. The content of lutein increased slightly after boiling in water containing 1% NaCl ($9.3\pm0.4{\mu}g$/g DW), while a loss in lutein occurred after preparation using other home-processing methods. A cis-isomer of all-trans-$\beta$-carotene, 13-cis-$\beta$-carotene, was present in detectable amounts in all processed samples, but not in raw roots. Another isomer, 9-cis-$\beta$-carotene, was detected in carrots that were prepared by boiling, frying and pressure-cooking.

This meta-analysis was conducted to evaluate the association between intake of carotenoids and risk of esophageal cancer. A systematic search using PubMed, Cochrane Library, Web of Science, Scopus, CNKI, and CBM (updated to 6 May 2012) identified ten articles meeting the inclusion criteria with 1,958 cases of esophageal cancer and 4,529 controls. Higher intake of beta-carotene, alpha-carotene, lycopene, beta-cryptoxanthin, lutein, and zeaxanthin reduced esophageal cancer risk with pooled ORs of 0.58 (95% CI 0.44, 0.77), 0.81 (95% CI 0.70, 0.94), 0.75 (95% CI 0.64, 0.86), 0.80 (95% CI 0.66, 0.97), and 0.71 (95% CI 0.59, 0.87), respectively. In subgroup analyses, beta-carotene showed protective effects against esophageal adenocarcinoma in studies located in Europe and North America. Alpha-carotene, lycopene, and beta-cryptoxanthin showed protection against esophageal squamous cell cancer. This meta-analysis suggested that higher intake of carotenoids (beta-carotene, alpha-carotene, lycopene, beta-cryptoxanthin, lutein, and zeaxanthin) is associated with lower risk of esophageal cancer. Further research with large-sample studies need to be conducted to better clarify the potentially protective mechanisms of carotenoid associations risk of different types of esophageal cancer.

Forty plants used as tea materials were chosen for determining the contents of total phenolics, selenium (Se), ${\beta}-carotene$, ${\alpha}-tocopherol$ and ascorbate. Total phenolics and ascorbate contents were analyzed colorimetrically. The Se contents were measured by hydride-atomic absorption spectrometry. The contents of ${\beta}-carotene$ and ${\alpha}-tocopherol$ were simultaneously determined by high performance liquid chromatography using separate detectors, UV for ${\beta}-carotene$ and FL for ${\alpha}-tocopherol$ analyses. The contents of these antioxidants were as follows (per 100 g dry plant); Contents of total phenolics in green tea leaf, black tea leaf, oolong tea leaf and instant coffee were about 7 g and the Se contents in corni fructus and arrowroot were found to be about $4{\mu}g$, which were the highest among all plants used. Contents of ${\beta}-carotene$ in eucommiae cortex, persimmon leaf and green tea leaf were 8587, 6222 and $3652\;{\mu}g$ respectively. The persimon leaf contained the highest ${\alpha}-tocopherol$ content (33 mg) and then followed by eucommiae cortex (26 mg), green tea leaf (16 mg) and black tea leaf (13 mg) in order. Ascorbate contents were found to be high in green tea leaf (199 mg) and black tea leaf (117 mg).

Normal healthy non vegetarian and lact$\infty$,vo­v vegetarian women were studied after they con­S sumed carrot juices as supplements. Daily sup­p plementation resulted in significant increase in serum levels of $\alpha$-, $\beta$-carotene and total carote­n noid in nonvegetarians and $\alpha$-and $\beta$-carotene in lactoovovegetarians. Reflection in serum and $\beta$-carotene was higher in nonvegetarians m than lactoovovegetarians. However, serum caro­t tene values were not significantly different between group after continous supplementation of reducing amounts of carotenes. Serm retionol levels were not changed throughout the study period and were not significantly different bet­w ween nonvegetarians and lactooovegetarians. The results suggest that serm total carotenoid cannot bean indicator of individual carotene such as $\alpha$-or $\beta$-carotene in serum and serum carotene levels are closely related to dietary carotene intake both in nonvegetartins and lac­t toovovegetanans

Purpose: This study was conducted to examine the effects of the starch concentration of filled hydrogel and the addition of ${\alpha}-amylase$ and simulated mastication processing in an oral phase on lipid digestion and ${\beta}-carotene$ bioaccessibility of filled hydrogels. Methods: Lipid digestion and ${\beta}-carotene$ bioaccessibility of the filled hydrogels were measured after the samples were passed through an in vitro gastrointestinal tract model consisting of oral, gastric, and small intestinal phases. Results: The initial rate and final extent of lipid digestion were higher in the filled hydrogels than in the emulsion when the filled hydrogels were treated in an oral phase without simulated mastication processing and addition of ${\alpha}-amylase$, regardless of starch concentration. However, when the filled hydrogels were minced using mortar and pestle for 2 min and were exposed to ${\alpha}-amylase$, the filled hydrogel fabricated with 5% starch showed the lowest lipid digestion rate and extent compared to the emulsion and other filled hydrogels. Bioaccessibility of ${\beta}-carotene$ was higher in the filled hydrogels than in the emulsion, regardless of the digestion method performed in an oral phase and starch concentration. However, there were appreciable differences in bioaccessibility of the filled hydrogels depending on whether or not simulated mastication and addition of ${\alpha}-amylase$ were employed. Conclusion: These results suggested that the rheological properties of initial filled hydrogels and simulated mastication processing in an oral phase plays an important role in determining the lipid digestion and ${\beta}-carotene$ bioacccessibility entrapped within filled hydrogels.

The carotenoids of 14 Korean Citrus were analyzed by HPLC and spectrophotometry. Selected Citrus varieties were Satsuma mandarins, Orange, Ponkan, Marumeru and Iyeagam. The amount of carotenoid in peel and juice of Citrus is $0.82{\sim}10.64\;mg%$ and $0.23{\sim}3.38\;mg%$, respectively. Among the 14 peaks obtained from each samples, ${\alpha}-carotene$, ${\beta}-carotene$, Iycopene and lutein were identified by the direct comparison with authentics. Eigth peaks were assumed to neoxanthin, violaxanthin, antheraxanthin, lutein-5,6-epoxide, isolutein, cryptox-diepoxide, cryptox-5,6-epoxide and ${\beta}-cryptoxanthin$ through reference $t_R$ and two peaks remained unknown.

Gamma irradiation treatment brings about biochemical changes that could affect nutritional Quality of food. This study was conducted to examine the content of $\beta-Carotene$ in Jeju orange, vitamin $D_3$ in anchovy and $\alpha-Tocopherol$ in beef. $\beta-Carotene$ content of Jeju orange was not affected by irradiation of 5 and 10kGy. In anchovy, vitamin $D_3$ content was dose-dependently increased to $109.30\%\;and\;125.25\%$ of original content by irradiation of 5 and 10kGy, respectively. $\alpha-Tocopherol$ content in beef with high fat was progressively reduced by $17\%$ of original value with irradiation of 1kGy and by $84\%$ with 10kGy. It could be concluded that $\alpha-tocopherol$ might be most vulnerable to irradiation, while vitamin $D_3$ is very stable against irradiation within 10kGy of gamma irradiation.

This study was performed as a part of comparative biological studies of carotenoid pigment for the unutilized biological products. The content of total carotenoid in the integument of wild catfish were 0.27(${\pm}$0.7) mg％ and composed of 25.8％ zeaxanthin, 9.7％ diatoxanthin and 9.1 ％ cynthiaxanthin as major carotenoid. The content of total carotenoid in the integument of cultured catfish were 0.07(${\pm}$0.03) mg％ which is relatively lower compare to wild catfish and composed of 48.5％ lutein, 13.9％ zeaxanthin and 13.3％ isocryptoxanthin as major carotenoid. The total carotenoid contents of the slender catfish were 0.75(${\pm}$0.25) mg％ which is relatively higher compare to other species of catfishes. The carotenoids were composed of 24.5％ zeaxanthin, 24.1 ％ 7'8'-dihydro-${\beta}$-carotene-4-ol, 17.9％ 7'8'-dihydro-${\beta}$-carotene and 10.8％ 7'8'-dihydro-${\beta}$-carotene-3-01 as major carotenoid and 8.7％ diatoxanthin, 6.7％ cynthiaxanthin and 5.0％ lutein as minor carotenoid. Based on these data, as a comparative studies of carotenoid in integument of siluridae, parasiloxanthin and 7',8'-dihydroparasiloxanthin which are the characteristic carotenoid of catfish from biwa lake in Japan, Slender catfish contained more based on 7',8'-dihydro-${\beta}$-carotene while that of wild and cultured catfishes were not found, indicating that carotenoid pigment of slender catfish depend on their living conditions.
