The purpose of this study was to investigate the effects of Curcuma aromatica powder on the functional and sensory characteristics of Mandupi. Various Mandupi samples were prepared with wheat flour along with addition of various amounts of Curcuma aromatica powder, after which instrumental characteristics and sensory evaluations were investigated. According to the amylograph data, the composite Curcuma aromatica powder-wheat flour samples showed increased gelatinization temperatures with increasing Curcuma aromatica powder content, whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of Hunter's color values, L value decreased while a and b values increased with increasing Curcuma aromatica powder content. Besides cooked weight, cooked volume and turbidity of Mandupi increased as the addition level of Curcuma aromatica powder increased. In terms of textural characteristics, addition of Curcuma aromatica powder increased springiness, chewiness, and brittleness, whereas springiness and adhesiveness decreased. Based on sensory evaluations, the overall preference of Mandupi with 3% added Curcuma aromatica powder was higher than that of control.

This study covers the historical aspects of the turmeric and curcuma only in detail on the medicinal uses, supported by references to the medical texts. And the result is as follows: 1. Turmeric and curcuma are rhizomatous herbaceous perennial plants of the ginger family, but both produced on the same herb. The rhizome is considered turmeric while the tuber is considered curcuma. 2. Turmeric is the round, oval, or ovate, and scutiform rhizome. 3. Curcuma is yellowish externally, internally more or less orange-yellow passing into reddish-brown. The tuber has a round and cuspidate appearance. The smell is aromatic, somewhat analogous to ginger. 4. Turmeric is somewhat analogous to curcuma in shape, but turmeric is pungent and bitter in taste, warm and intoxious in property, and yellow in color, acting on the spleen and liver channels and governing the gi of the blood while curcuma is pungent and bitter in taste, cold and intoxious in property, red in color, acting on the heart and pericardium channels and governing the blood. 5. Turmeric is referred to zedoary, sliced turmeric, old jaundice, precious aromatic, and ovate rhizoma, and curcuma is referred to radix curcuma, curcuma aromatica, and cicada-belly curcuma

The antimicrobial activity of Curcuma aromatica Salab. was investigated. The Curcuma aromatica Salab. extract showed antimicrobial activity against six pathogens tested. These were Listeria monocytogenes ATCC 19115, Pseudomonas fluorescens ATCC 21541,Staphylococcus aureus ATCC 29273, Salmonella typhimurium ATCC 21541, vibrio parahaemolyticus ATCC 17802, and Aeromonas hydrophila KCTC 2358. Antimicrobial activity was alsonoted when the extract was tested against four isolates of Bacillus sp. purified from spoiled tofu. The growth of various pathogens was significantly inhibited (100 10,000-fold) upon growth in tryptic soy broth containing 0.05 0.2%(w/v) Curcuma aromatica Salab. extract(CE), after incubation for 12hr at $37^{\circ}C$. The growth of the four Bacillus isolates was also significantly inhibited in nutrient broth containing 0.05 0.2% CE after incubation for 24hr at $37^{\circ}C$. Although the antimicrobial activity of CE was decreased by heat treatment at temperatures above $80^{\circ}C$, the activity remained relatively high after heat treatment at $121^{\circ}C$ for 15min. The minimum inhibitory concentrations of CE were 0.1 0.3%(v/v culture) for the six pathogens, and 0.2 0.25% for the Bacillus isolates, respectively.

This studies were engaged to investigate the potential us of Curcuma aromatica Salab. as a food ingredients. The antimicrobial activity of Curcuma aromatica Salab. extract (CE) and effect on shelf life of the cooked rice were examined. The antimicrobial activity of CE showed apparently against Bacillus cereus, B. subtilis and B. megaterium. The minimum inhibitory concentration (MIC) of CE was 0.15% for B. cereus md 0.2% for B. subtilis and B. megaterium. The antimicrobial activity of CE remained relatively high after heat treatments(30 min at 80 and $100^{\circ}C$, 15 min at $121^{\circ}C$). The shelf life of cooked rice containing above 0.05% CE increased more 1 or 2 days than that of control at $30^{\circ}C$, The texture of cooked rice was improved by addition of above 0.01% CE. The sensory quality of cooked rice with CE did not show significant difference between 0.00% and 0.05% in taste and overall acceptability but decreased above 0.10% in taste, color, flavor and overall acceptability.

The effects of various concentrations (0.01% 0.02% both v/v) of a Turmeric (Curcuma aromatica Salab.) ethanol extract (CE) on the shelf life of tofu were investigated during tofu storage for 12 d at $25^{\circ}C$. The total number of bacteria in tofu containing 0.02% CE was ca. 100 1,000-fold lower than that of the control after this period Tofu containing CE had a lower pH then did control curd, but was higherin titratable acidity, during the storage period. Measurement of hardness, cohesiveness, and springiness of tofu containing CE were higher than those of control during storage. Each of these parameters of texture value improved (increased) with an increase in the concentration of CE in tofu The degree of whiteness of tofu did not differ between samples with or without CE. The yellowness of tofu increased after addition of CE. The overall acceptability of tofu containing CE was lower than that of control.

The purpose of this study was to observe the effects of antibacterial activities on various medicinal herbs. Medicinal herbs used this study was Curcuma aromatica, Scutellaria baicalensis, Angelica dahurica, Platycodon grandiflorum, Houttuynia corolata, and Forsythia saxatilis. To evaluation of the antibacterial effect, we used S. gallinarum(ATCC 9184), S. typhimurium(SAL-13, France), S. enteritidis (ATCC 10376), Escherichia coli(E-62, O78), and S. gallinarum(E. coli). Extracts from each medicinal herbs divided into 100mg/ml, 50 mg/ml, 25 mg/ml, and 12.5 mg/ml. Antibacterial activities achieved by the paper disc test. Antibacterial activities was showed at extracts from Scutellaria baicalensis, Houttuynia corolata, Forsythia saxatilis, but little found at Curcuma aromatica, Angelica dahurica, Platycodon grandiflorum.

This experiment was carried out to investigate the effects of medicinal plant by-products on productivity and egg quality in laying hens. A total of five hundred sixty laying hens was randomly distributed into 7 treatments with 4 replicates of 20 birds per replicate and fed com-soy based experimental diets containing 1.5% and 3.0% by-products of Cordyceps militaris, Artemisia capillaris and Curcuma aromatica S., respectively for 12 weeks. Egg production was not significantly different among treatments. Haugh unit was significantly increased in all treatments compared to control(p<0.05). There was no difference among the treatments in egg shell breaking strength, shell thickness, and yolk color. In conclusion, three medicinal by-products used in this experiment did not affect feed intake, egg production and showed positive effect on Haugh unit when they used $1.5{\sim}3.0%$ of feed.
