This study investigated the effect of supplement of the pigment source in diets on body color for round tailed paradise fish Macropodus chinensis and the pale chub Zacco platypus. Fish (the round tailed paradise fish: 1.6 g/ fish, pale chub: 2.4 g/fish) were fed diets containing various pigment sources (Porphyra powder, Spirulina powder. yeast astaxanthin and paprika extract) twice a day for 6 weeks. Survival of all treatments was above 80%. Weight gain and total carotenoid contents of round tailed paradise fish fed the diet containing Porphyra powder was higher than that of fish fed the other diets. The apparent redness of skin and fin in round tailed paradise fish fed the diets containing paprika extract and yeast astaxanthin was better than that of fish fed the diets containing Porphyra powder, Spirulina powder and the control diet. Weight gain and total carotenoid contents of pale chub fed the diet containing paprika extract were higher than that of fish fed the containing Porphyra powder, yeast astaxanthin, Spirulina powder and the control diet. The apparent redness of skin and fin in pale chub fed the diets containing parika extract and yeast astaxanthin was better than that of fish fed the diets containing Porphyra powder, Spirulina and the control diet. The results of this study suggest that dietary supplementation with paprika extract and yeast astaxanthin can improve redness of skin and fin of round tailed paradise fish and pale chub.

The relative efficiencies of deposition into egg yolk of apo-carotenoic acid ester(APO-E, CAROPHYLL Yellow) and saponified marigold xanthophylls (MX), in the presence of canthaxanthin (CN), were determined using a wheat-based diet. APO-E was deposited with an efficiency of 50 percent and MX with an efficiency between 13 and 20 percent. The dose response relationship for MX was curvilinear with a decreased efficiency at higher concentrations. Canthaxanthin was deposited with and efficiency of 38 percent, irrespective of the source of yellow xanthophylls, up to a dietary concentration of 5.5 mg/kg. At a dietary MX concentration of 8.3 mg/kg the efficiency of deposition of CN declined to 24 percent. The results confirm that the replacement ratio of MX : APO-E is between 3 : 1 and 4 : 1 depending on the dietary inclusion of marigold pigment.

Objective: This study aimed to explore the effects of different types of xanthophyll extracted from marigold on the growth performance, skin color, and carcass pigmentation. Methods: A total of 192 healthy 60-day-old yellow-feathered broilers weighing an average of 1,279±81 g were randomly allocated to 4 groups, each with 6 replicates and 8 broilers. The 4 treatments were as follows: i) CON group, fed with basal diet; ii) LTN group, supplemented with lutein; iii) MDP group, supplemented with monohydroxyl pigment including dehydrated lutein, β-cryptoxanthin, and α-cryptoxanthin; iv) LTN+MDP group, supplemented with lutein and monohydroxyl pigment in proportion to 1:1. The supplementary content of LTN, MDP, and LTN+MDP was 2 g/kg. Skin color was measured after 7, 14, 21, and 28 days of feeding the dietary treatments. The breast, thigh, and abdominal fat of slaughtered chickens were stored in cold storage at 4℃ for 24 hours and then the meat color of lightness (L^*), redness (a^*), and yellowness (b^*) values was determined. Results: The results showed that all treatments enhanced the yellow scores of subwing skin on day 14, 21, and 28 (p<0.05), and the mixture of lutein and monohydroxyl pigment promoted the yellow scores of shanks on day 14, 21, and 28 (p<0.05). The mixture of lutein and monohydroxyl pigment increased the yellow scores of beaks and all treatments enhanced the yellow of shanks on day 28 (p<0.05). In addition, all treatments improved the yellow (b^*) values of breast and thigh muscle, moreover, the monohydroxyl pigment and the mixture of lutein and monohydroxyl pigment enhanced the values of redness (a^*) and yellow (b^*) of abdominal fat (p<0.05). Conclusion: In summary, different types of xanthophyll extracted from marigold significantly increased the yellow scores of skin color and the yellow (b^*) values of carcass pigmentation. Especially, the mixture of lutein and monohydroxyl pigment was more efficient on skin color.

This study was conducted to investigate the optimal condition of the extraction of red pepper oleoresin. The yield of oleoresin form red pepper was 24~28% when it was extracted by ethanol and methanol. and 8~10% by acetone, ethylene dichloride and n-hexane. But more than 60% of portion in alcohol extracts were moisture and sugars. Capsaicin and pigment were extracted more than 70% of those in red pepper when it was extracted by ethylene dichloride Those useful components were extracted most efficiently by mixed solvents of ethanol and ethylene dichloride at the ratio of 50:150. other extracting conditions were investigated in this studies, such as optimal extraction time was more than 3 hours, temperature was 55$^{\circ}C$ and particle size was finer than 250 mesh

To utilize the ascidian tunic as a natural pigment and dietary sources for rainbow trout (Oncorhynchus mykiss), juvenile were fed on experimental diets containing enzymatic hydrolysates of ascidian tunic treated with three commercial mined enzymes (ultrazyme, cellulase, viscozyme) for 12 weeks. From the results of feeding experiment, similar growth rate was checked in the enzymatic hydrolysis group compared with control, and those were a higher than of ascidian tunic powder group. The total acetone extractable pigment in muscle of the enzymatic hydrolysates group was lower than that of the ascidian extracts group and carophyll pink group until 8 weeks, but the level of those pigment of the enzymatic hydrolysates was similar to the ascidian extracts and carophyll pink group after 12 weeks. The lipid content was increased with the pigment concentration in the all experimental group. But the ascidian tunic pigment did not influence on the composition of the fatty acids in the muscle and liver. From the consideration of results for pigmentation, the enzymatic hydrolysates of ascidian tunic were suitable for both a natural pigment and dietary protein and carbohydrates sources as a substitute synthetic pigment for aquaculture use.

This experiment was conducted to investigate the effects of dietary pigment sources on the performance, color and antioxidant properties in broiler chick. Experimental diet was formulated to have isocalories and isonitrogen during the experiment period. Total xanthophylls content in the experimental diet was formulated to have 30ppm. Experimental trials were done for five weeks with six treatment groups; T1 (Control), T2 (Olo Glo, natural yellow pigment), T3 (Kern Glo, natural red pigment), T4 (canthaxanthin, synthetic red pigment), T5 (asthaxanthine, natural red pigment), and T6 (seaweed by-products). Body weight gain and feed intake were significantly lower (p＜0.05) in T6 group than in other treatments. Mortality was lower in T2, T3 and T4 than in control, but higher (p＜0.05) in T5 and T6. The sources of pigments did not have any effects on the dressed carcass and abdominal fat pad (p＞0.05). The gizzard weight was significantly lower in T6 (p＜0.05) than in others. Pigmentation of leg skin was significantly lower (p＜0.05) in control and T6. Effects of dietary pigments was greater with red pigments than with yellow pigments, and those were also greater with natural pigments than with synthetic ones. The peroxide value (POV), thiobarbituric acid reactive substances (TBARS) and pH values of chicken meat were increased (p＜0.05) in all treatments at 12 day storage, and was higher (p＜0.05) in pigments supplementation group. No differences of CIE L$\^$*/(lightness) and b$\^$*/(yellowness) were not found by storage days and xanthophylls sources. The a$\^$*/(redness) after 12 day storage was significantly (p＜0.05) decreased in all treatments, but those of T4 and T5 were higher than those of others. These results showed that feeding of xanthophylls sources to chick could improve color intensity and inhibit lipid oxidation of leg meat.

Curcumin, a dietary pigment responsible for the yellow color of curry, has been used for the treatment of inflammatory diseases and exhibits a variety of pharmacological effects such as anti- inflammatory, anti-tumor, anti-oxidant, and anti-viral activity. In order to examine the potency of the curcumin in inflammation we used carrageenan induced rat hind paw odema model. As curcumin is practically water insoluble, it is hypothesized that pharmacological activity of curcumin could be improved by enhancing its water solubility. Water soluble complexes of curcumin with cyclodextrins were prepared and screened for greater solubility. Pure curcumin 100 mg/kg body weight along with curcumin complexes equivalent to 100 mg/kg body weight of pure curcumin were tested for the anti-inflammatory activity in Wister rats male rats using carrageenan induced hind paw edema model and compared with that of the reference compound diclofenac sodium at a dose level of 10 mg/kg body weight. Results were statistically analyzed using ANOVA. All the treatment groups showed statistically significant anti-inflammatory activity compared with that of vehicle control and positive control.

This experiment was conducted to investigate the effects of natural and synthetic commercial pigments on the growth performances, skin pigmentation and color difference of broiler chicks. Experimental diet was formulated to have isocalories and isonitrogen for experimental period, and xanthophyll concentration in the diet was 8.45g/1on. The experiment was conducted for six weeks with 450 broiler chicks. The birds were assigned to 10 treatment groups and each group had 15 chicks with three replications. Results showed that the types of pigments did not have any effect on body weight, feed intake and feed efficiency. The mortality was lower with higher pigment supplementation and greater in the natural pigment groups than in the synthetic ones. Dressed carcass, abdominal fat pad and gizzard weight were not significantly different among treatments. The pigmentation of shank skin was increased with high pigment supplementations, and the pigmentation effect was greater with synthetic pigments than in natural pigments. In the shank meat or skin, the color difference(L*, a*, b*, c* and h*) was not consistently related to pigmentation.

In order to determine the utilization of ascidian tunic, which has been blamed for problems of costal environmental pollution when discharged into the sea after being used as a natural dietary pigment sources for rainbow trout(Oncorhynchus mykiss), fingerlings were fed on experimental diets containing acetone-extracts for 6 weeks. The amounts of acetone-extracts were 11,000mg/Kg and contained 50mg/100g wet tissues of carotenoid and $6\%$ of carotenoids were astaxanthin. From the results of feeding experiments, the growth rate in the extract group was a little higher than that of the control and pink groups after 6 weeks. The redness and yellowness of the fish skin and muscle in the extract group were similar to the pink group. Therefore, acetone-extracts of ascidian tunic were judged to be a natural dietary pigment source suitable as a substitute synthetic pigment for aquaculture use.
