Abstract

Reducing caffeine was meant for improving health effect of drinking coffee. Meanwhile supplementation of functional food ingredient such inulin and fructooligosaccharides (FOS) in coffee beverage is expected for emerging health value of decaff coffee. Decaffosin instant coffee was formulated from decaffeinated coffee powder enriched with 27 % w/w inulin powder and 7 % fructooligosacharides (FOS). This study aims to identify nutritional quality and to evaluate the effect of inulin and FOS addition at the same time on preference level of Dekafosin instan coffee. The result of showed that Dekafosin instan coffee contain 5.04 % of water and 2.3 % of mineral. Total reducing sugar, sucrose, glucose, fructose and soluble dietary fiber content of the beverage are 30.83, 0.47, 2.8, 94.33 and 98.1 percentage, respectively. Meanwhile, caffeine and inulin content of the the beverage are 1.23 and 28.15 percentage. The statistical analysis proved that decaffeination and the supplementation of inulin and FOS did not influence on the preference level of Dekafosin instant coffee, as showing by the following value : preference level of colour (x² count = 17.397 < x² table = 18.549), aroma (x² count = 5.563 > x² table = 4.168) and taste (x² count = 11.413 < x² table = 14.684) wich has a significance value (p) > 5 percent. Therefore, based on this analysis data it can be concluded an addition of inulin and FOS did not influence preference level toward Dekafosin instant coffee beverage.Keywords : decaffeinated coffee, inulin, FOS, Dekafosin instant coffee beverage, nutritional quality, preference level

Abstract

The effect of two fractions of oleoresin compounds from ginger root on lymphocyte function were studied by observing B cell proliferations, which were  measured by the incorporation of 3H-thymidine during cell incubation. The doses of oleoresin compounds and its two fractions tested were 50,100, 150, and 200 mg per ml. Lymphocyte from human peripheral blood were isolated using ficoll density gradient technique, and cultured  in the presence of the compounds in RPMI-1640 medium for 4 days, with or without the addition of 3 mM paraquat as the oxidizing agent.  The results showed that the effects of oleoresin and its two fractions depended on its doses. Oleoresin and its two fractions increased B cell proliferation with  the highest activity of 456 percent at low dose of 50 mg per ml. These result showed a positive effect of oleoresin compound and its two fractions on B cell functions  at low doses. It indicated that bioactive compounds of ginger root at low  concentration have  positive effects on humoral immune response and this supports the traditional belief that ginger increases body resistance to common cold.
