  • Omeprazole is usually administered as encapsulated enteric-coated granules and enteric-coated tablets because of its acid-labile nature. For children and patients who can not swallow, it can be mixed with water or other liquid after a capsule is opened or a tablet is crushed. This study was performed to compare omeprazole liquid formulations of tablet and capsule Omeprazole 20 mg capsule containing enteric coated granules was opened and 20 mg entric-coated tablet was ground to be mixed with sodium bicarbonate solution, orange juice or water. Each liquid formulation was poured into dissolution tester, mixed with first solution (artificial gastric juice; pH 1.2) for two hours, then with second solution (artifical enteric juice; pH 6.8) for thirty minutes. pH was measured periodically for two and half hours. Samples were drawn periodically, mixed with lansoprazole as an internal standard, and injected to HPLC. As results, pH of sodium bicarbonate solution of omeprazole was significantly higher than that of orange juice or water in first solution (6.2-7.4 vs. 1.2, p<0.005). At 150 min, concentrations of omeprazole in three diluents with granules and in sodium bicarbonate solution of tablet powder sustained significantly higher than in other solution of tablet powder (p<0.001). In conclusion, enteric-coated granules from capsule with three diluents and powder from tablet in sodium bicarbonate solution was stable during dissolution test, which would be appropriate and recommended for patient who can not swallow solid preparations.

  • Objectives: The aim of this study was to evaluate the effect of fruit juices on Multi-Drug Resistant (MDR) bacterial pathogens involved in Urinary Tract Infections (UTIs) and Sexually Transmitted Infections (STIs) among tribal women in the district Anuppur, Madhya Pradesh, India. Methods: Fresh juices of lemon (Citrus limon), amla/Indian gooseberry (Phyllanthus emblica), pineapple (Ananas comosus), mosambi/sweet lime (Citrus limetta), orange (Citrus sinensis), kiwi (Actinidia deliciosa), and pomegranate (Punica granatum) fruits were evaluated for in vitro antibacterial activity against bacterial pathogens involved in UITs and STIs among tribal women. Physico-chemical analysis of fresh fruits was also carried out by measuring the pH, moisture, protein, fat, crude fibre, carbohydrate, and ascorbic acid content. Results: Lemon and amla juice showed better antibacterial activity against the pathogens as compared to other juices. MIC results fruit juices against UTIs and STIs pathogens vary depending on the specific pathogen and juice chemical constituents. The physico-chemical analysis showed that the moisture content was highest in mosambi (90%), followed by orange (87%). Ascorbic acid content was found highest in amla (540 mg/100 g), followed by kiwi (90.3 mg/100 g). Pomegranate showed highest concentration of carbohydrate (15.28 g/100 g), fat (1.28 g/100 g), and protein (1.65 g/100 g). Lemon juice had lowest pH of 2.20, followed by amla 2.67. Conclusion: The lemon juice showed highest antibacterial activity against MDR bacterial pathogens involved in UTIs and STIs among tribal women in district Anuppur, Madhya Pradesh, India. The low pH of lemon may be responsible for its high antibacterial activity as compared to other juices.

  • This research examined the quality characteristics of orange sauce samples prepared with different sugar contents in order to create a standardized recipe.In the foodservice industry, attempts have been made to make superior sauces, often resulting in error. In this study, different sugar contents were examined for orange sauce to determine why varied results occur during its preparation as well as the best methodology for preparing orange sauce. Quality characteristics such as color differences, spreadability, and pH were analyzed, as well as sensory evaluations of taste, texture, color and overall acceptability. The pH values of the orange sauce samples ranged from 3.6 to 3.63 and after the initial simmering of ingredients, the weight reduction rates of the sauces were 88, 75, 64, 63, and 64% for sugar contents of 200, 300, 400, 500, and 600 g respectively. Hunter's color L, a, and b values of the samples changed according to the sugar contents after simmering (1st sauce). The L and b values showed similar patterns, where increasing sugar content resulted in higher values; however, in the 2nd sauce, the pattern was reversed. This indicates that the color of the sauce was affected by sugar caramelization during the reduction process; however, the final color was modified by the additions of mayonnaise and butter as well as by aeration. In the sensory evaluation the sample containing 30% sugar (500 g) had significantly higher acceptability scores (p<0.05) for color, mouth feel, appearance, taste, and overall acceptability. Finally, the optimal ingredient ratios of the standardized orange sauce recipe were determine as: 48% total liquid consisting of orange juice and mandarin and orange fruit; 30% sugar; 10% mayonnaise and 11% butter.

  • The purpose of this study is to evaluate nutritional status of ascorbic acid in 96 Korean female college students. Dietary intake level was estimated with three day diet records. Serum ascorbic acid were analyzed with fasting blood. Nutrient intakes was calculated using three different food composition databases ; analysis data of cooked food items ; analysis data of raw foods ; published food composition table. Ascorbic acid intake levels calculated with different food composition databases differed by 15% Using analysis data of cooked foods resulted in the lowest intake level 49.26 mg per day. Main sources of ascorbic acid investigated were Cheju mandarin orange juice and hard persimmon orange juice and Kimchi. Mean value of serum ascorbic acid level was 1.04 mg/dl and 4.2% of subjects were in marginal risk or deficient range. It was found to significantly correlate asscorbic acid intake with serum ascorbic acid content. Correlation coefficient with results calculated using analyzed data was higher than that using published data. Serum levels and mean daily intake levels of ascorbic acid in the subjects were significantly correlated. From these results it is concluded that ascorbic acid content of cooked foods should be included in the Food Composition Tables in Korea. Korean female college students were in lower risk of ascorbic acid deficiency.

  • Objectives: The purpose of this study was to identify the correlation between calcium in soft drinks and enamel remineralization. Method: Six soft drinks were used in this study. These were calcium milk, normal milk, calcium yoghurt, normal yoghurt, calcium orange juice, and orange juice. Enamel specimens which 300- 400Vickers Hardness Number (VHN) were selected. These samples were immersed in each soft drink for 12 hours in an in vitro remineralization model. All specimens were processed for SEM image of the enamel surface. Results were analyzed by SPSS 13.0 package program. Results: Calcium milk was the most influential and normal yoghurt was the least to enamel surface. There was not significant difference according to calcium supplement in milk although the difference of enamel hardness was ${\Delta}f13.4$ in calcium milk, and ${\Delta}f4.7$ in normal milk (P>0.05). Other soft drinks showed a little change about calcium but they were insignificant. Demineralization effect was remarkably observed in calcium yoghurt ($-{\Delta}f269.1$) and this effect was confirmed by SEM images. In conclusion, calcium supplemented soft drinks had little influences to hardness of enamel surface.

  • The aim of this study was to evaluate the in vitro effects of exposure to acidic beverages on microhardness of enamel and dentin. Thirty enamel specimens and thirty dentin specimens were obtained from extracted bovine maxillay incisiors. Enamel and dentin specimens were divided into three groups and treated with acidic beverages as follows; Group 1 : cola(pH 2.52), Group 2 : plain soda water(pH 2.93) and Group 3 : orange juice(pH 3.75). Erosive treatment was performed by storing each specimens for 5 min in 50ml solution of cola, soda water and orange juice. Average microhardness values(VHN) were determined before and after erosive treatment. All beverages produced significant loss of microhardness of enamel and dentin. Microhardness of enamel was reduced in the following order: Group 1 : $42.71{\pm}4.36(%)$, Group 2 : $37.09{\pm}6.25(%)$, Group 3 : $35.46{\pm}4.98(%)$. Microhardness of dentin was reduced in the following order: Group 1 : $17.14{\pm}3.42(%)$, Group 2 : $13.89{\pm}3.18(%)$, Group 3 : $13.82{\pm}3.50(%)$. The differences between group 1 and group 2, 3 were statistically significant(p< 0.05).

  • We have determined the contents of monosaccharides in the hydrolysates of some yogurt and orange juice products by derivatizing monosaccharides with p-aminobenzoic acid ethyl ester (ABEE). The separation of the ABEE-derivatized monosaccharides was efficiently carried out by HPLC using a microcolumn packed with the Alltima $C_{18}$ stationary phase. The concentrations of monosaccharides were determined based on the measured peak area/height counts. ABEE derivatization of fructose and its detection have never been successfully carried out before this work. In this study, two peaks were observed in a fixed ratio for ABEE-fructose, and the ratio was maintained over a wide range of fructose concentration. In order to prove the validity of the above method, we compared the concentrations of glucose, galactose and fructose determined by ABEE derivatization and UVD (ultraviolet detector) chromatography with those determined by RID (refractive index detector) chromatography without derivatization. The determined concentrations of monosaccharides obtained from the two chromatographic methods were found close to each other within acceptable error ranges.

  • Thickened beverages or swallowing aid jelly (SAJ), commonly used as tablet-swallowing aids for dysphagic patients, may influence the disintegration of orally administered tablets. With this in mind, we evaluated the disintegration times of therapeutic tablets immersed in thickened beverages or SAJ compared to immersion in ones without them. Thickened beverages and SAJs were prepared with various beverages (water, orange juice, and milk) using food thickeners and SAJ powders marketed in Korea. The tablet disintegration times were the same in thickened beverages and SAJs, and there was no statistically significant difference associated with the thickness levels of the thickened beverages. The disintegration times of Tylenol immersed in orange juice or milk were slightly higher compared to those immersed in water. Moreover, there was no difference in disintegration time when using the thickened beverages and SAJs. The disintegration times of Aspirin were similar in all of the thickened beverages or SAJs, and there were no differences between non-immersed and immersed tablets. These results demonstrate that the disintegration of Tylenol and Aspirin is not greatly affected by immersion in any of the thickened beverages and SAJs.

  • The purpose of this study was to evaluate the tooth brightening of whitening dentifrice and to determine the tooth stain level over 20 days depending on beverages that have various pH values after using whitening dentifrice. Thirty teeth were randomly divided into two groups. Group 1 was provided with a whitening dentifrice for 3 minutes and group 2 was treated with a control dentifrice for 3 minutes thrice a day for four weeks. All teeth were photographed using a digital imaging system under a stereomicroscope (magnification, ${\times}10$). After four weeks, the ten teeth were immersed in the tea solution, another of ten teeth were immersed in the orange juice and the other of the teeth were immersed in the coffee solution. Three solutions were renewed each day for the appropriate groups. Stain development was monitored under a stereomicroscope daily over 20 days period by immersion of teeth in a tea, juice, coffee solution at room temperature ($25^{\circ}C$) in individual container. Whitening dentifrice gave a statistically higher value of overall color change as compared to control dentifrice after 21 days (p<0.05). Stain level of whiten tooth immersed in orange juice was the grestest overall color change, but there was not statistically significant difference (p>0.05). On the other hand, stain level of whiten tooth immersed in coffee and green tea showed a statistically significant difference after 15 days and 5 days, respectively (p<0.05). Tooth immersed in green tea was higher negative value than control dentifrice. The tooth using whitening dentifrice was shown to be effectively whiter color than control dentifrice. However, stain level by orange juice, coffee and green tea has a strong staining effect.
