Carotenoids are abundant int he Korean food supply. The intake of foods rich in carotenoids appears to be associated with optimal health, and a reduction in the risk of cancer, cardiovascular disease, macular degeneration and cataract formation. Specific dietary carotenoids may be responsible for these specific protective effects. Hydrocarbon carotenoids such as $\alpha$-,$\beta$-carotenes and lycopene may reduce the risk of cancer and heart disease, whereas oxygenated carotenoids, such as lutein and zeaxanthin, may be important in protection of the eye. Dietary carotenoids, such as lutein, cryptoxanthin, $\alpha$-carotene, $\beta$-carotene and lycopene can be readily obtained from the diet, Green leafy vegetables, such as spinach and broccoli, contain both oxygenated and hydrocarbon carotenoids ; yellow or orange vegetables, such as carrots, have high levels of $\alpha$-carotene and $\beta$-carotene ; and tomatoes contain high amounts of lycopene. Besides being important vitamin A sources, provitamin A carotenoids such as $\alpha$-carotene, $\beta$-carotene and cryptoxanthin, participate in the cell defense systems that are associated with radical quenching. Non-provitamin A carotenoids, such as lutein and lycopene, major carotenoids in human plasma, have also been reported to possess strong antioxidant capability. The alteration of dietary sources of carotenoids can modify their levels in the circulation and target tissues, and thus prevent or delay the onset of these chronic diseases.

A feeding trial was conducted to investigate the effects of dietary carotenoids sources on growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi. Nine experimental diets (designated as Con, CP, PA, SP, OP, MB, TO, BE and PO) were formulated to contain Carophyll Pink, red paprika, Spirulina, Opuntia, mandarin bark, tomato, beet and Porphyra, respectively. Each experimental diet was fed to two replicate groups of fish (22.9 g/fish) to visual satiation three times a day for 8 weeks. Weight gain and feed efficiency of fish fed the diets containing Spirulina or Opuntia were higher than those of fish fed the control diet (P<0.05). The values of $a^*$, $L^*$ and $b^*$ of fish skin were significantly changed by dietary carotenoids sources (P<0.05). The $a^*$ values of fish fed the diets containing Carophyll Pink, red paprika and Spirulina were higher than those of fish fed other diets (P<0.05). The skin total carotenoids of fish fed the diets containing Spirulina and Opuntia were higher than those of others (P>0.05). Based on the results of this study, it can be concluded that dietary inclusion of red paprika and Spirulina pacifica could increase the skin redness of red- and white-colored fancy carp.

This study was conducted to investigate effects of dietary pigment sources on shell color of juvenile abalone, Haliotis discus hannai. Three replicate groups of the abalone, average weight 173 mg, were fed the diets containing various pigment sources such as Porphyra powder, Spirulina, yeast astaxanthin and paprika extract for 16 weeks. Survival and weight gain were not affected by dietary pigment sources (P>0.05). Shell color of abalone fed diets containing Porphyra powder and Spirulina was approached to yellow-red and orange which are similar to shell color of wild abalone. However, shell color of abalone fed the diets containing yeast astaxanthin and paprika extract were similar to that of control diet showing bright green. Porphyra powder and Spirulina contain not only fat-soluble pigment such as chlorophyll and carotenoids but also water-soluble pigment such as phycoerythrin and phycocyanin. These results would be useful information to change shell color of abalone in aquaculture.

The feeding value of high-oil corn fed to Taiwan Country (TC) chicken was examined by measuring apparent metabolizable energy (AME), growth performance, sexual maturity, carcass characteristics, and plasma pigmentation. In a completely randomized design, 870 sex-intermingled one-wk-old chicks were assigned to one of 30 floor pens, 29 birds per pen, and each pen randomly assigned to one of five dietary treatments. The experiment was ended when birds were 16 wk of age. The five dietary treatments varied in main fat sources, which were corn oil (CO), high-oil corn (HOC), lard (LRD), whole soybean (WSB) and yellow corn (YC), respectively. All the diets were formulated isonitrogenously, isocalorically, and of equal lysine and methionine contents except YC, in which equal amounts of YC replaced HOC. The results indicated that feed conversion in HOC was 8% higher (p<0.05) than YC whereas the calculated AME of HOC was only 3.5% to 4.0% higher than that of YC. No significant differences were observed in body weight, body weight gain, feed consumption, feed conversion ratio and ME efficiency for body weight gain among CO, HOC, LRD, and WSB. No significant differences existed in both skin and muscle pigmentation of breast among the five dietary treatments. No significance differences existed in plasma carotenoid content measured at various ages among the five dietary treatments except that birds fed with HOC had less (p<0.05) plasma carotenoids at 16 wk-old. The results indicate that if the price of high-oil corn is no more than 1.05 times that of yellow corn, the dietary cost per kg of body weight gain for TC chickens fed diets containing high-oil corn will be less, although their body weight may be lighter compared to chickens fed diets formulated with other fat sources.

This study aimed to evaluate the effects of various plant-derived carotenoid extracts on growth parameters and skin coloration of golden trevally (Gnathanodon speciosus). Five groups of fish were fed diets containing carotenoid sources from the petal extracts of the leopard tree (Caesalpinia ferrea), wild sunflower (Tithonia diversifolia), marigold (Tagetes erecta), yellow bells (Tecoma stans), Wedelia chinensis (Wedelia chinensis), along with a control group, each diet had a carotenoid concentration of 0.25 g/kg feed. The diets were based on the same fundamental ingredients and administered for 56 days. Results showed significant differences in growth parameters among the different diets, with wild sunflower and marigold petal extracts proving most effective in enhancing the skin coloration of golden trevally. High yellow (CIE b^*), ranging from 17.2 to 18.8, were observed (Minolta CR-400), compared to only 12.2 ± 0.34 in the control group. Additionally, the carotenoid content in the tissue of the various groups differed significantly (p < 0.05), with the highest level of carotenoids (71.2 ± 2.9 ㎍/g tissue) detected in the fish skin of the dietary marigold flower group (UV-visible spectrophotometry). It is suggested that the petals of wild sunflowers and marigolds can efficiently improve body pigmentation and growth performance in golden trevally, indicating that these plant-derived carotenoids may have potential applications in aquaculture.

To determine vitamin A and E intakes and their food sources, dietary intakes were collected by three consecutive 24-hour recalls from 192 adults living in Seoul and Gyeonggi Province, Korea. The mean vitamin A, retinol and ${\beta}$-carotene intakes were $1240.1{\pm}1101.1\;{\mu}g$ retinol equivalent/day ($693.3{\pm}563.2\;{\mu}g$ retinol activity equivalent/day), $182.6{\pm}149.5\;{\mu}g$/day and $5443.3{\pm}6365.5\;{\mu}g$/day, respectively. Only 9.4% of the subjects consumed less than the Korean Estimated Average Requirement for vitamin A. The mean vitamin E intake was $6.03{\pm}2.54\;mg$ ${\alpha}$-tocopherol equivalent/day. The ${\alpha}$-tocopherol and ${\gamma}$-tocopherol intakes were $4.83{\pm}2.03$ and $5.57{\pm}3.41\;mg$/day, respectively. Most of the subjects (93.8%) consumed less than the Korean Adequate Intake for vitamin E. The major food sources of vitamin A were sweet potato, carrot, red pepper powder, spinach, and citrus fruit, and the top 30 foods provided 91.5% of total Plant foods provided 81.0% and animalderived foods 10.5% of the vitamin A intake from the top 30 foods. The major food sources of vitamin E were soybean oil, red pepper powder, Ramyeon (cup noodles), spinach, and egg. The top 30 foods provided 78.0% of total vitamin E intake. Plant foods provided 61.3% and animal-derived foods 15.9% of the vitamin E intake from the top 30 foods. In conclusion, the vitamin A intake of the Korean adults in this study was ge-nerally adequate, but the vitamin E intake of many subjects was inadequate. Therefore, nutritional education may be of benefit to Korean adults to increase their vitamin E intake.

The purpose of this study was to estimate the daily intake of vitamin A in Korean female university students. Vitamin A intake was estimated using an inconsecutive 3-day dietary intake survey from 481 young women. Vitamin A intake values were calculated based on the data in USDA database. Average age, height, and weight of the subjects were 20.05 years, 162.13 cm and 54.38 kg, respectively. The subject's average intake of energy was 1645.67 kcal. The mean vitamin A, retinol and ${\beta}$ carotene intakes were $908.35{\pm}863.18$ ug retinol equivalent/day, $199.19{\pm}166.00$ ug/day and $3872.59{\pm}4972.17$ ug/day, respectively. The 21.83% of the subjects consumed less than the Estimated Average Requirement (EAR) for vitamin A. And subjects consumed 141.69% of the Recommended Nutrient Intake (RNI) for vitamin A. Food groups consumed with high vitamin A content in our subjects included vegetables (423.96 ug RE/day), potato and starches (213.64 ug RE/day), cereals (62.60 ug RE/day), eggs (55.17 ug RE/day) and milks (53.45 ug RE/day). The major food sources of vitamin A were sweet potato, carrot, spinach, egg, and cereal, and the top 30 foods provided 89.57% of total vitamin A. Also animal-derived food provided 9.65% of the vitamin A intake from the top 30 foods. In conclusion, judging from RNI, the vitamin A intake of the Korean female university students in this study was generally adequate. The result of our study may be used as a basis for follow-up studies of vitamin A intake like assessment of vitamin A nutritional status or evaluation of carotenoid food sources in Korean young women.
