  • This study was conducted the physicochemical and sensory characteristics of Bulgogi sauce added with concentrated Curcuma longa L.. Increasing the amount of concentrated Curcuma longa L. in the Bulgogi sauce tended to increase the pH values, lightness(L), redness(a) and yellowness(b) values. It also tended to increase DPPH radical activity, but total polyphenol contents of Bulgogi sauce added with concentrated Curcuma longa L. were not significantly different among all the samples. In sensory evaluation, Bulgogi sauce added with 10% concentrated Curcuma longa L. had an excellent score in sensory taste, but Bulgogi sauce added with 20% concentrated Curcuma longa L. had an excellent score in overall preference. Seasoned roasted beef addition with 20% concentrated Curcuma longa L. had an excellent score in sensory preference. Therefore, this results suggest that 20% concentrated Curcuma longa L. should be applied to Bulgogi sauce for high sensory preference.

  • Objectives : The anticancer response of three different types of water extracts of Zingiberaceae Curcuma longa L. tested for sarcoma 180. Only few studies carried out to investigate the effects of other contents of Curcuma longa L. in anticancer activities, therefore, in this study we have investigated the effects of other component then curcumin in Curcuma longa L. for anticancer a activities. Methods : Three different types of water extracts of Curcuma longa L. were prepared as follows. The sarcoma cells (S180) were maintained in Dulbecco's modified Eagle's medium (DMEM) and were seeded on 24-well cell culture cluster flat bottom with lid tissue culture treated non-pyrogenic polystyrene. The growth of sarcoma 180 was monitored for 1, 2 and 5 days. The sarcoma cells were pictured using inverted microscope and cell density was counted using hemocytometry. Results : After 5 days in the culture medium the results showed high growth of sarcoma 180 for control condition and the surface of CCP plates were fully covered with the cells. In case of medium in which the 10% of filtered water extract of Curcuma longa L. was added a very limited growth of sarcoma 180 was observed. The results were showed only small difference in cell density for two different concentrations of unfiltered water extracts of Curcuma longa L. whereasin case of filtered water extracts the control of sarcoma growth shows better result. Conclusion : The filtered water extracts showed the best result relatively to the unfiltered water extracts for two different concentrations. This indicates that the water extracts of Curcuma longa L. can have anticancer activities possibly without curcumin.

  • The present study investigated the immunomodulatory effects of Curcuma longa L. ethanol extracts on natural killer (NK) cells and T cells. We treated Curcuma longa L. ethanol extracts at concentrations of 20, 50, 100, and $150{\mu}g/mL$ to murine NK cells co-incubated with YAC-1 cells. Curcuma longa L. ethanol extracts resulted in increased NK cell activity compared to the control group at all concentrations. In the groups treated with Curcuma longa L. ethanol extracts, CD69 and IFN-${\gamma}$ expression levels significantly increased compared to the control group at 100 and $150{\mu}g/mL$. In addition, Curcuma longa L. ethanol extracts induced significant elevation of CD8+ T cell numbers in a dose-dependent manner. However, Curcuma longa L. ethanol extracts also led to reduction of CD4+ T cell and MHCII numbers. The findings of this study suggest that Curcuma longa L. ethanol extracts could enhance the immune response through activation of NK and cytotoxic T cells due to a proliferative shift of antigen presentation from MHCII to MHCI, presumably.

  • This study was conducted to investigate rheological and sensory characteristics of fish paste prepared with Curcuma longa L. powder (0, 1, 3, 5, 7%). The moisture content of the fish paste ranged from 71.35 to 72.97%. Increasing the amount of Curcuma longa L. powder in the fish paste tended to decrease the pH value and the folding test good score in all samples. Increasing the amount of Curcuma longa L. powder in the fish paste also tended to decrease the lightness (L) in the hunter color value, but to increase the redness (a) and yellowness (b). For the textural characteristics, the addition of Curcuma longa L. powder increased the strength and decreased the springiness. In a sensory evaluation, the addition of 3% Curcuma longa L. powder had the best score in taste and overall preference. Therefore, this results suggest that adding 3% Curcuma longa L. powder would be feasible for making Curcuma longa L. fish paste.

  • The immune system protects the body against harmful substances and infectious agents. Normally, the body can maintain a state of immune homeostasis. However, failure of immune homeostasis results in severe diseases when the immune system is defective. We investigated the immunomodulatory effect of Curcuma longa L. extract in LP-BM5 MuLV (murine leukemia viruses)-induced murine AIDS (acquired immune deficiency syndrome). Mice were divided into six groups: normal control, infected control (LP-BM5 MuLV infection), positive control (LP-BM5 MuLV infection+dietary supplement of red ginseng 200 mg/kg), CL50 (LP-BM5 MuLV infection+dietary supplement of Curcuma longa L. 20% alcohol extract 50 mg/kg), CL200 (LP-BM5 MuLV infection+dietary supplement of Curcuma longa L. 20% alcohol extract 200 mg/kg), and CL500 (LP-BM5 MuLV infection+dietary supplement of Curcuma longa L. 20% alcohol extract 500 mg/kg). We found that dietary supplementation with Curcuma longa L. 20% alcohol extract inhibited elevation of spleen, lymph node, and liver weights as well as reduction of T- and B-cell proliferation and natural killer cell activity induced by LP-BM5 MuLV infection. Moreover, Curcuma longa L. 20% alcohol extract inhibited Th1 (IL-2, IFN-${\gamma}$)/Th2 (IL-4, IL-10) cytokine imbalance and pro-inflammatory cytokine production. In conclusion, these data suggest that Curcuma longa L. has immunomodulatory effects in LP-BM5 MuLV-induced murine AIDS.
