This experiment was conducted to investigate the dietary effect of turmeric powder (TP) on laying performances, egg qualities and its transfer to eggs. A total of two hundred, 60-wk-old, Lohmann Brown layers were divided into 4 groups, placed in to 5 replicates per group (10 layers each) and fed each one of four diets containing 0 % TP(control), 0.1 % TP, 0.25 % TP, or 0.5 % TP for 7 wks, respectively. Egg production and egg mass in groups fed diets containing TP were higher than that of control(p<0.05). No differences in feed intakes, egg and eggshell qualities were observed among the treatments, but egg yolk color was increased significantly as TP was in increased in the diet(p<0.05). In groups fed diets containing TP, Haugh unit after 14 day of storage was significantly higher than that of control(p<0.05). The curcumin content of egg yolk in groups fed diet containing 0.50% TP was significantly higher than those of other groups (p<0.05). The content of egg yolk cholesterol was not influenced by dietary TP.

The composition of turmeric powder (TP) can affect the quality properties and storage characteristics of pyeonyuk; however, the appropriate addition level of TP in pyeonyuk has not been established. To address this, an experiment was designed with one control and three TP treatments: control (TP 0%), T1: (TP 0.1%), T2: (TP 0.3%), and T3: (TP 0.5%). All the TP treatments markedly increased protein and ash contents compared to the control. The water holding capacity was equally retained with the control and T3 treatments, but was significantly lower with the T1 and T2 treatments in pyeonyuk (p<0.05). Lightness and redness values were both reduced with the addition of TP, whereas the yellowness value increased. Values for 2-thiobarbituric acid reactive substances and the total microbial count for pyeonyuk with added TP showed an improvement over time. As a result, the addition of TP did not have a significant negative influence on the quality characteristics of the pyeonyuk with addition of 0.5% TP being particularly effective for water retention capacity and inhibition of lipid oxidation.

Different herbs and spices have been used as feed additives for various purposes in poultry production. This study was conducted to assess the effect of feed supplemented with black pepper (Piper nigrum), turmeric powder (Curcuma longa), coriander seeds (Coriandrum sativum) and their combinations on the performance of broilers. A total of 210 (Cobb) one-d-old chicks were divided into seven groups of 30 birds each. The treatments were: a control group received no supplement, 0.5% black pepper (T1), 0.5% turmeric powder (T2), 2% coriander seeds (T3), a mixture of 0.5% black pepper and 0.5% turmeric powder (T4), a mixture of 0.5% black pepper and 2% coriander seed (T5), and a mixture of 0.5% black pepper, 0.5% turmeric powder and 2% coriander seeds (T6). Higher significant values of body weight gain during the whole period of 5 weeks (p<0.001) were observed in broilers on T1, T3, T5, and T6 compared to control. Dietary supplements with T1, T2, T3, and T6 improved the cumulative G:F of broilers during the whole period of 5 weeks (p<0.001) compared with control. The dressing percentage and edible giblets were not influenced by dietary supplements, while higher values of relative weight of the liver (p<0.05) were obtained in T5 and T6 compared to control. The addition of feed supplements in T5 and T6 significantly increased serum total protein and decreased serum glucose, triglycerides and alkaline phosphatase concentrations compared with the control group (p<0.05). Broilers on T6 showed significant decrease in the serum glutamate pyruvate transaminase concentration (p<0.05) compared to control. The broilers having T5 and T6 supplemented feed had relatively greater antibody titre (p<0.001) at 35 d of age than control. It is concluded that dietary supplements with black pepper or coriander seeds or their combinations enhanced the performance and health status of broiler chickens.

Dyeing properties of cow leather was investigated with Tumeric powder. The effects of dyeing conditions, mordanting conditions, color change, and color fastnesses were studied. The results were as follows. The dye uptake increased as dye concentration, dyeing temperature, and bath ratio increased. In the effect of dyeing time, the highest dye uptakes showed at 20 minutes and decreased after that point. Pre mordanting was more effective than the post mordanting, and the dye uptakes improved all mordanted fabrics. The highest K/S values showed in pre-Al sample, and the lowest K/S values showed in post-Cu one. The values of Hunter on the samples were more changeable $L^*$ and $b^*$ than $a^*$, and all samples showed Yellow color in Munsell value. But the mordanting methods and mordanting agents were not significant in the color changes. The light fastness of dyed samples showed 1 grade, the dry cleaning and abrasion fastnesses did not improved except post-Fe wet sample.

This study was carried out to examine the electron donating ability (EDA), nitrite scavenging, tyrosinase inhibition, ACE inhibition and fibrinolytic activity of culture extracts from Fomitella fraxinea which was grown added rice bran, pine needles and turmeric in brown rice. Electron donating ability was higher in the extract by hot water than ethanol. Nitrite scavenging activity was the highest from ethanol extract of culture products added to the pine needles, showed the scavenging activity was approximately 50%. Tyrosinase inhibition activity was highest in the extract by hot water, showed inhibition rate of rice bran was 72.49%, pine needles 87.34% and turmeric powder 82.75%, respectively. ACE inhibition activity were very low effective at all water and ethanol extracts. Fibrinolytic activities were similarly strong in the rice bran, pine needles and turmeric powder. Especially, when the rice bran and turmeric powder were added, showed the activities were increased about 10% than plasmin. Therefore, it may be used for the food and cosmetic industry as natural source of bioactive compound after further investigation such as in vivo experiment.

The purpose of this study was to investigate the effect of turmeric on antioxidative systems and oxidative damage in rats fed a high fat and cholesterol diet. A total 40 rats were divided into four experimental groups: a normal diet group (N), a high fat and cholesterol diet group (HF), a high fat and cholesterol diet group supplemented with 2.5% turmeric powder (TPA group) and a high fat and cholesterol diet group supplemented with 5% turmeric powder (TPB group). The serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) activity of the turmeric supplemented groups were decreased compared to the HF group. The GPT activity of the TPB group was especially and significantly decreased compared to the HF group. Hepatic superoxide dismutase (SOD) of the TPB group was significantly increased compared to the HF group. However, there were no significant differences in the activities of hepatic glutathione peroxidase (GSHpx) and catalase (CAT) among all experimental groups. Hepatic glutathione S-transferase (GST) activity in the TPA and TPB groups were increased compared to the HF group. Hepatic superoxide radical content in mitochondria of the 5% turmeric supplemented group was significantly decreased compared to the HF group. Hepatic hydrogen peroxide content in the cytosol and mitochondria of the turmeric-supplemented groups were decreased compared to the HF group. Hepatic carbonyl values in the mitochondria of the turmeric supplemented groups were significantly decreased compared to the HF group. Thiobarbituric acid reaction substance (TBARS) values in the liver were significantly reduced in turmeric supplemented groups compared to the HF group. These result suggest that turmeric powder may reduce oxidative damage through the activation of antioxidative defense systems in rats fed high fat and cholesterol diets.

This study was designed to investigate the effects of fermented turmeric extract on body weight, abdominal fat mass and biochemical markers related to obesity in rats fed high fat diet. Turmeric and brown sugar was equally mixed and fermented for one year. Wistar rats (weighing about 125 g (15 rats)) were divided into three groups: high fat diet (20.9%) and brown sugar 7.2% (HFD), turmeric powder in replace of corn starch 12.8%, brown sugar 7.2% (TP), fermented turmeric powder 20% (FTP) for four weeks. The final body weight was about 425g. The retroperitoneal fat weights in TP group showed the tendency to decrease regardless of feed intake in the rats. Serum levels of total cholesterol and LDL-cholesterol in the FTP group showed the lowering tendency than those of the HFD group (p<0.05). Serum levels of leptin, adiponectin and aspartate aminotransferase (AST) in the FTP group was significantly (p<0.05) lower than that of the HFD group, and serum level of tumor necrosis factor-$\alpha$ (TNF-$\alpha$) in all the groups were similar. These results suggest that fermented turmeric extract might be effective to prevent obesity in rats fed high fat diet.

A total of two hundred, 60-wk-old, Lohmann Brown layers were divided into 4 groups, placed in to 5 replicates per group (10 layers each) and fed each one of four diets containing 0% TP (control), 0.10, 0.25 or 0.50% TP, respectively, for 7 wks. Egg production in the all groups fed diets containing TP were significantly higher than that in control (P<0.05). No differences in feed intakes, egg and eggshell qualities were observed among the treatments, but Roche color fan number (yolk color) in group fed diet with 0.5% TP was significantly higher than in control (P<0.05). In the groups fed diets containing TP, Haugh units after 2 wk of storage were significantly higher than that of control (P<0.05). The curcumin content of egg yolk in the groups fed diet containing 0.50% TP was significantly higher than those in the other groups (P<0.05). The cholesterol levels of egg yolk were not influenced by dietary TP. It was concluded that dietary TP was effective in improving laying performance and internal egg qualities. TP can be also used as a feed additive for the production of value-enhanced eggs with increased yolk color and curcumin content.

Antimutagenic effects of extracts from curry powder and its individual fourteen kinds of spices, were investigated by Ames test. The antimutagenic effects against a direct mutagen, 2-nitrofluorene(2 -NF) and two indirect mutagens, 2-anthramine(2-AT) and 2-acetamidofluorene (2-AE) in the S. typhimurium TA98 were tested. For the 2-NF, the antimutagenicity of cinnamon, fenugreek, fennel, ginger, clove, turmeric and celery seed were determined as 42, 38, 32, 28, 24, 23 and 20%, respectively. The antimutagenicity of clove against the 2-AT was the highest (116%), and followed by the order of celery seed(103%), cardamon(100%), red pepper(99%), cinnamon(92%), cumin(83%), ginger(82%), fennel(82%), coriander (71%), nutmeg(68%) and turmeric (55%). The results also showed that the antimutagenic effect of clove against the 2-AF was superior to other spices. In case of curry powder among more than 10 kinds of spices, the antimutagenenicity against the 2-AT and 2-AF showed 23% and 6%, respectively, but no effect was observed against the 2-NF.
