Despite a range of commercially available oligosaccharides there is plenty of room to develop new, functionally enhanced prebiotics. current generation of oligosaccharides was not rationally developed. better understanding of factors determining the prebiotic activity of a particular oligosaccharide. Despite the range of commercially available oligosaccharides mixtures (mainly fructo and galacto-oligosaccharides, very few studies are focused on the mechanisms behind the prebiotic activity of particular oligosaccharides. Probably this lack is due to the unavailability of well characterized oligosaccharide fractions for prebiotic function assessment. The objectives of this research were to asses the ability of lactic acid bacteria in fermentation of oligosaccharide and as prebiotic (in vitro. Material used was oligosaccharide of purified rumbia fruit extract. Analysis of oligosaccharide as prebiotic was conducted in vitro using lactic acid bacteria. The lactic acid bacteria consisted Bifidobacterium bifidum, Bifidobacterium animalis, Lactobacillus bulgaricus and Lactobacillus casei Rhamnosus. The growth media for bacteria was a liquid MRS basic medium where glucose was substituted by oligosaccharide of purified rumbia fruit extract. Incubation was in aerob for Lactobacillus and anaerob for Bifidobacterium in incubator 37oC. The lactic acid bacteria was calculated 24-48 hours during incubation periode. The variables observed were: oligosaccharide component, ability of lactic acid bacteria in fermentation of oligosaccharide, and growth of lactic acid bacteria (Lactobacillus and Bifidobacterium. The result showed that the oligosaccharide component from extract rumbia fruit consisted of: sucrose, stacchiose, and raffinose. The result showed that the oligosaccharide extract rumbia fruit was significantly (P<0.05 the growth of lactic acid bacteria (Lactobacillus and Bifidobacterium and fermentation of oligosaccharide.

    Full Text Available Anti-caries effect of gambier extract on male wistar rats. Several previous studies have mentioned that gambir extract can inhibit the growth of Streptococcus mutans (S. mutans because it contains active substances of catechins and tannins. The objective of this study was to explore the anti-caries effect of gambir extract on male Wistar rats. Thirty-six Wistar rats were inoculated with S. mutans, given cariogenic foods and divided into 4 groups according to the doses of gambir extract, namely 6 mg, 12 mg, 24 mg and placebo. After 60 days, the rats were euthanized, then the number of caries on the mesial or distal and occlusal surfaces was counted by using the Keyes’ method. The data were analyzed using Kruskal Wallis test. The results revealed that caries was found only in occlusal surfaces with an enamel depth. There is no significant difference among all the groups, so it can be concluded that gambir extract at 6 mg, 12 mg and 24 mg doses do not have anti-caries effect on the teeth of male Wistar rats.   ABSTRAK Beberapa penelitian terdahulu mengatakan bahwa ekstrak gambir dapat menghambat pertumbuhan Steptococcus mutans (S. mutans karena mengandung zat aktif katekin dan tanin. Tujuan dari penelitian ini adalah untuk melihat efek antikaries ekstrak gambir pada tikus jantan galur Wistar.

    2009-12-01

    Full Text Available Penelitian penggunaan ekstrak teh hijau (Camellia sinensis sebagai penghambat pembentukan histamin pada ikan telah dilakukan. Ikan, terutama dari jenis skombroid, sangat rentan mengalami kerusakan karena terjadinya perubahan asam amino histidin yang terkandung dalam ikan menjadi senyawa histamin yang bersifat alergen, yang dikatalisasi oleh enzim histamin dekarboksilase (HDC. Teh hijau diketahui mengandung polifenol berupa senyawa epigalokatekingalat (EGCG yang merupakan penghambat enzim HDC, sehingga dekarboksilasi histidin menjadi histamin dapat dicegah. Perendaman ikan tongkol dalarn ekstrak teh hijau pada konsentrasi 0, 2, dan 4% dilakukan selama 30 menit, diikuti dengan pernindangan dalam larutan gararn 15% selama 30 menit diteruskan dengan penyimpanan ikan pindang pada suhu kamar. Pengambilan sampel dilakukan setiap hari selarna 4 hari penyimpanan untuk diamati perubahan mutu kimiawi (TVB dan kadar histarnin, mikrobiologi JPC dan bakteri pembentuk histamin, serta organoleptik (kenampakan, bau, tekstur, lendir, rasa. Hasil penelitian menunjukkan bahwa ikan yang direndam dalam ekstrak teh 4% mempunyai kadar histamin 21,3 ppm, jauh lebih rendah dibandingkan dengan ikan yang direndam dalam ekstrak teh 2% dan 0% yang masing-masing mencapai 64,4 pprn dan 101,4 ppm. Penghambatan pembentukan histamin oleh ekstrak teh hijau masih terjadi selama penyimpanan, yang terlihat dari rendahnya jumlah bakteri pembentuk histarnin dan kadar histamin dibandingkan dengan kontrol. Pada penyimpanan hari ke-3, penghambatan pembentukan histamin oleh ekstrak teh hijau tidak efektif, kemungkinan karena terlalu tingginya jurnlah bakteri pembentuk histamin, yaitu mencapai 108 cfu/g.

    We experimentally demonstrate the high conversion efficiency, low cost, green technology and easy to fabricate dye-sensitized solar cells (DSSCs) using natural anthocyanin dyes as sensitizers. The DSSCs was fabricated by using natural anthocyanin dyes which were extracted from different parts of the plants inclusive `Buah Mertajam', `Buah Keriang Dot', `Bunga Geti', Hibiscus, Red Spinach and Henna. The natural anthocyanin dyes that found in flower, leaves and fruits were extracted by the simple procedures. This anthocyanin dye is used to replace the expensive chemical synthetic dyes due to its ability to effectively attach into the surface of Titanium dioxide (TiO2). A natural anthocyanin dyes molecule adsorbs to each particle of the TiO2 and acts as the absorber of the visible light. A natural anthocyanin dye from Buah Mertajam shows the best performance with the conversion efficiency of 5.948% and fill factor of 0.708 followed by natural anthocyanin dyes from `Buah Keriang Dot', `Bunga Geti', Hibiscus, Red Spinach and Henna.

    Full Text Available Meningkatnya kesejahteraan masyarakat Indonesia berdampak positif bagi peningkatan jumlah pasar tradisional dan komoditas perdagangannya. Namun, permasalahan sampah yang ditimbulkan oleh kegiatan perdagangan tersebut masih belum dapat ditangani dengan baik. Tidak hanya itu, sampah pasar tradisional yang hanya ditimbun di area tempat pembuangan akhir (TPA telah menyebabkan pencemaran lingkungan berupa kontaminasi air tanah, emisi gas rumah kaca dan masalah kesehatan. Sampah pasar tradisional memiliki potensi yang besar untuk diolah menjadi biogas melalui metode anaerobic digestion. Dengan adanya mikroorganisme, proses ini mampu mendegradasi sampah organik menjadi bahan organik yang stabil dan biogas (metana dan karbondioksida. Salah satu faktor yang mempengaruhi proses tersebut adalah adanya senyawa-senyawa antibiotik yang terkandung dalam sampah. Senyawa capsaicinoid dalam sampah buah cabai merupakan senyawa yang berperan dalam rasa pedas cabai memiliki pengaruh negatif terhadap kinerja mikroorganisme dalam mendegradasi sampah menjadi biogas. Pengaruh konsentrasi buah cabai terhadap produksi biogas ini belum banyak diteliti dan diketahui sehingga perlu dilakukan penelitian untuk menentukan konsentrasi minimal yang menyebabkan proses inhibisi (penghambatan.Hasil penelitian membuktikan adanya pengaruh konsentrasi buah cabai (capsaicinoid terhadap produksi biogas. Sampah pasar tradisional dengan konsentrasi 8 g VS/liter yang diumpankan terhadap konsorsium mikroorganisme tanpa adanya buah cabai menghasilkan yield biogas yang lebih tinggi dibandingkan dengan sampah yang tercampur buah cabai. Semakin tinggi konsentrasi buah cabai semakin besar pengaruh penghambatannya (inhibition. Hal ini ditunjukkan dengan menurunnya yield biogas yang dihasilkan. Konsentrasi buah cabai yang menghasilkan yield optimal diperoleh pada nilai konsentrasi 5 dan 8 g VS/liter untuk cabai merah dan cabai rawit secara berturut-turut.

    Full Text Available Soymilk has become progressively consumed in Indonesia since early 1990. However, soymilk has a short shelf life due to its high protein content that promotes growth of spoilage microorganisms. This study was aimed at utilizing peel waste of eggplant (Solanum melongena L. and dragon fruit (Hylocereus polyrhizus, to prolong shelf life of fresh soymilk through microbial growth inhibition, so that it will not be easily contaminated during storage, transportation and distribution time to meet the needs of consumers. Microbiological analysis showed a notably higher inhibitory effect of dragon fruit peel extract when soymilk was stored at 4ºC and it exhibited lower number of colonies even after 6 days. Interestingly, the antimicrobial activity of eggplant peel extract in cold soymilk could only be observed on day 3 until day 9. Hence, it is assumed that chlorogenic acid, as a primary antimicrobial agent in eggplant peel, needed certain time interval to activate its inhibitory activity against microorganism. However, the two peel extracts could not prolong the shelf life of soymilk stored at ambient temperature. All soymilk samples added with the peel extracts fulfilled the Indonesian National standards (SNI for pH value, protein, and total solid content. Based on the sensory evaluation, the samples with dragon fruit peel extract attained a comparable acceptance level as plain soymilk and were favored over those added with eggplant extract. In conclusion, this research indicated potential applications of usual household waste of dragon fruit and eggplant peels as antimicrobial agents for protein-rich beverages.

    Full Text Available The aims of the study was to determine antihyperuricemic activity of ethyl acetate and ethanol extractsof snake fruit (Salacca edulis Reinw. var. Bongkok on Wistar male rats. Wistar male rats administered with 100 and 200 mg/kg b.w ethyl acetat extract and 200 mg/kg b.w ethanol extract and simulationsly induced with potassium oxonate peritoneally and uric acid orally showed descreased uric acid serum level significantly as compared to control group at 6th and 7thhour (p < 0.05. Meanwhile ethanol extract at 100 mg/kg bw did not affect uric acid serum level significantly. Determination of uric acid level in urine of the rats, indicated that administration ofethanol extract at 200 mg/kg bw, orprobenecid as a standard at 45 mg/kg bw, increased excretion of urine uric acid level significantly as compared to control group at 7thhour (p < 0.05. Additionally, administration of ethyl acetate extract at 100 and 200 mg/kg bw did not show an increase of uric acid excretion in urine. Mechanism of action of the ethyl acetate extract and ethanol extract as an antihyperuricemic agent has been proposed by inhibition of xanthine oxidase activity wich decrease the synthesis of uric acid. Hence, the mechanism of action of antihyperuricemia of the ethanol extract was suggested to be an uricosuric i.e. increases the excretion of urine uric acid and xanthine oxidase inhibitory.

    Full Text Available Election ink is applied to the forefinger of voters during election in order to prevent electoral frauds such as double voting. The current election inks contain silver nitrate solutions to make it more durable which stains the skin on exposure to ultraviolet light, leaving a mark that is impossible to wash off and is only removed as external skin cells are replaced. But the silver nitrate solution may damage the human skins and is poisonous to the environment. This research was carried out to investigate the use of gambir extracts for election inks as environment-friendly raw materials. The aim of this study was to obtain the optimal ink from gambir extrac which technically could meet quality requirements of the election ink. In this study, gambir was extracted through the following refinement process; heating in boiling water, stirring, cooling, filtering, molding, and drying.

    Full Text Available Mangosteen can be stored for a relatively long period in low temperature storage, but peel hardening due to lostof moisture makes it difficult to open before consumption. One attempt to solve this problem is the application ofsemi-cutting treatment before storage of the fruits at low temperature. However, semi-cutting will acceleratedeterioration process since it increases fruit respiration and creates a door to microorganism to enter and spoil thefruit. Waxing the fruit after semi-cutting helps to overcome the problems, so the fruit can be stored at lowtemperature for long period, but it can be opened easily before consumption. This research aims to find a suitablemethod of waxing as well as the best wax concentration solution for waxing process. The methods of waxingconducted in this research were dipping and smearing, while the wax concentration in solution for both methodswere 6, 9, and 12%. The results show that smearing the fruit after semi-cutting with 12% wax concentration gave thelongest self life for the mangosteen stored at low temperature, while the fruits were still easier to open afterstorage.

    Full Text Available Fermentation is one of bioconversion to produce profitable anaerobic microbes and to produce various enzymes. Lipases and cellulases are widely used enzymes so far. Cellulases play an important role in bioconversion of organic waste cellulosic materials to glucose, single cell proteins, animal feed, and ethanol. Lipases can also degrade fatty ester bond. Therefore, both enzymes are potential to be used in industry as well as in households. Fermentation of fruit peel waste is an attempt to produce cellulase and lipase that can be carried out in a simple way. Cellulase as says was performed using DNS (3.5-dinitrosalicylic acid and acid-base titration for analysis of lipase using cooking oil as the substrate. The results showed that the highest cellulase activity was obtained from watermelon rind mixed with citrus fruit peel of 0.036 U/mL, and mixed of banana peel and citrus fruit, which was 0.035 U/mL. The optimum lipase activity was at 30 oC, pH 7, and reaction time of 60 minutes. The highest lipase activity (1.36 U/mL was obtained from mixture of watermelon and orange rind. Thus, the fruit peel waste is potential to produce cellulase and lipase by fermentation .

The NCD mortality and prevalence can be prevented by practicing a healthy lifestyle. One of a healthy lifestyle is adequate vegetable and fruit consumption that unfortunately was still far from expectation in the Basic Health Survey 2007 and 2010. Puskesmas as primary health care should anticipate the problem by encouraging doctor to routinely ask and educate on a healthy lifestyle. Objective: This study aimed to assess physician ask and advice on vegetable and fruit consumption based on patient and physician report. Method: Two hundred and fifty-one patients from primary health care (Puskesmas in Yogyakarta City and Sleman District participated in this cross-sectional survey. Subsequently, a survey of 57 physicians was conducted. Data were collected by structured questionnaires and exit interviews. We analyzed the data using Chi-Square test and logistic regression. Results: The results showed that patients have been asked and advice about vegetable and fruit consumption. However, the proportion of physician report was higher than the proportion of patient’s report. Patient who had gastrointestinal disorder, had body weight problem, suffered from diabetics and cardiovascular diseases were more being asked and educated about vegetable and fruit consumption than other symptoms or diseases. Patients who were female, not married and did not eat vegetable and fruit everyday reported more being asked and advised by doctor on fruit and vegetable consumption than patients who were male, married and did not regularly eat fruit and vegetable. There was no difference of patient’ s perception of the relation between their disease and fruit and vegetables consumption based on characteristics, symptoms, disease and the frequency of eating fruit and vegetable. Conclusion: Primary health care physician has asked and advised patient about vegetable and fruit consumption although did not routinely practice it. Delivering advice as part of patient education on high fiber diet should be included in the national insurance scheme, so that physician will routinely educate patient.

    Full Text Available ABSTRACT The presence of mantled fruit on large-scale clonal production of oil palm had trully decreased the oil productivity. Mantled phenotype is likely to be that of an epigenetic change involving DNA methylation and the MADS-box transcription factor gene which encoded floral organ homeotic transformation. The objectives of this research were to quantify the degree of methylation which determined fruit abnormality through Ultra Performance Liquid Chromatography (UPLC and to study its correlation with the MADS-box EgAGL6, EgAG2, and EgAGA genes expressed on mantled fruit derived from oil palm clonal plants which have been quantified using Quantitative Real-Time PCR (qPCR. This research was arranged in two replications for each gene and cDNA. The expression of the target genes were compared to EF1-α1 as the reference gene. Through the Least Significant Difference (LSD Test at 95% confidence level of qPCR result, EgAGL6 expression was significantly lower in mantled fruit which decreased from 1.88 fold in Abn m to 0.46 fold in Abn. EgAG2 expression was increased non-significantly from 0.91 fold in Abn m to 1.13 fold in Abn, while EgAGA expression was higher in mantled which increased significantly from 1.48 fold in Abn m to 1.71 fold  in Abn. Nuclease S1 digestion and UPLC revealed the genome-wide increase in DNA methylation on mantled fruit (18.33-19.55% compared to its normal counterparts (5.67%. This increased in global DNA methylation was showed by the significant decreased in EgAGL6 transcript level of mantled fruit. This gene assumed to be involved in the development of mantled fruit. Keywords: DNA-methylation, MADS-box genes, Mantled fruit, Quantitative Real-Time PCR
