Abstract

Suweg (Amorphophallus campanulatus B1) is an indigenous tuber potentially used as an alternative food source. The objective of the study was to identify the functional properties, i.e. dietary fiber and Glicemic Index (IG) of Suweg by in vivo method using human. The experiment was conducted in three steps i.e suweg flour production, analysis of suweg flour functional properties, and determination of glycemic index (IG) using human. Suweg tuber had high content of dietary fiber (13,71%), and protein (7,20%) but had low fat content (0,28%). Suweg tuber had low IG (42) with low starch in vitro digestibility (61,75%), hence its was categorized as food product with low IG (

Abstract

The aims of this research were to investigate the prebiotic and synbiotic properties of sweet potato products (combined with L. casei subsp Rhamnosus for probiotic) in increasing the number of Lactic Acid Bacteria (LAB) and suppressing the number of E. coli and the occurrence of Salmonella in vivo. Some previous study showed that sweet potato is a potent source of prebiotic. The sweet potato products evaluated were sweet potato flakes (SPF) and sweet potato ice cream mix. The in vivo assay used male rat strain Sprague-Dawley. Total microbes, LAB, E. coli and Salmonella in fecal were analyzed before, during and after feeding period. Feeding with SPF as prebiotic, L. casei subsp Rhamnosus as probiotic, and combination of both as synbiotic for ten days were able to increase the number of LAB (0.4-1.1 log CFU/g) and suppress the number of E. coli in rat feces (1.5-1.7 log CFU/g). All of the treatment did not affect the occurrence of Salmonella in rat feces. The treatment of sweet potato ice cream mix as prebiotics and the combination of sweet potato ice cream mix and L. casei subsp. Rhamnosus as synbiotic for ten days did not effect the number of LAB and E. coli in rat feces.Key words: sweet potato, prebiotic, oligosaccharide, probiotic, synbiotic

Diterima 05 Agustus 2010 / Disetujui  20 Desember 2010 ABSTRACT   The effects of lintnerization (2.2 N HCl, 2 hours), debranching with pullulanase (1.3 U/g and 10.4 U/g starch) and/or three-auctoclaving-cooling cycles at 121oC for 15 minutes on the changes of arrowroot starch structures were studied. The structural modifications of amylose and amylopectin were measured by Gel Permiation Chromatography (GPC), and the distribution of degree of polimerization (DP) was analyzed by Fluorophore-Assisted Capillary Electrophoresis (FACE). The GPC profile of native starch using Toyopearl HW-65S gel gave mainly two fractions. Fraction I (Fr. I) was a high molecular weight component and Fraction II (Fr. II) was a low molecular weight component. After acid modification, the carbohydrate content of Fr. II increased while that of Fr. I decreased. The amount of  DP of 6 to 8 increased in all modified arrowroot starches. The GPC and FACE analyses showed that all starch modification techniques caused the structural changes of amylopectin molecules to form short chain amyloses.   Key words: arrowroot starch, degree of polimerization, FACE (Fluorophore-Assisted Capillary Electrophoresis) and GPC (Gel Permiation Chromatography)

METABOLISME PREBIOTIK OLEH KANDIDAT PROBIOTIK ISOLAT ASI SEBAGAI DASAR PENGEMBANGAN PRODUK SINBIOTIK [Prebiotics Metabolism by Probiotics Candidates Isolated from Breast Milk as a Basis for Development of Sinbiotics Product] Lilis Nuraida1,2)*, Nur Rita Mardiana2), Didah Nur Faridah1,2), dan Hana1) 1) South East Asian Food and Agriculture Science and Technology (SEAFAST) Center, Institut Pertanian Bogor 2) Departemen Ilmu dan Teknologi Pangan, Fakultas Teknologi Pertanian, Institut Pertaian Bogor   Diterima 05 Juli 2011 / Disetujui 22 November 2011   ABSTRACT   Five Lactobacillus strains and two Pediococcus strains isolated from breast milk were evaluated for their ability to metabolite oligosaccharide known as prebiotics, i. e. inulin, FOS, GOS, FOS:GOS (1:9), and inulin:GOS (1:9). The result shows that all Lactobacillus and Pediococcus strains were able to grow in medium with prebiotics as carbon sources. The best growth was observed when GOS or FOS were used as carbon source, while inulin was the worst. The best growth in all oligosaccharides was observed in Lactobacillus R23H, followed by L. rhamnosus B16, L. rhamnosus R23, and L. rhamnosus R14. Further study on R23H (heterofermenter) and R23 (homofermenter) shows that there was no difference in metabolizing oligosaccharides between heterofermenter and homofermenter. GOS was the best prebiotic used by the both lactic acid bacteria as shown by rapid decrease of total sugar. The reducing sugar in medium containing GOS was higher than other oligosaccharides. The decrease of total sugar in medium containing inulin was the slowest, indicating that inulin was the most difficult prebiotic to be metabolized by the lactic acid bacteria. When inulin mixed with GOS in the ratio 1:9, the rate of decreasing of total sugar in the medium was similar to the medium with GOS as single carbon source, however it cannot be distinguished if the role of inulin took place after GOS disappeared. The rate of sugar metabolism was in accordance with the growth of lactic acid bacteria isolates in medium containing prebiotics. L. rhamnosus R23 was used in sinbiotic fermented milk product combine with FOS, inulin, and inulin:GOS (1:9). After fermentation, remaining sugar in skim milk with additional prebiotics was higher than skim milk without additional prebiotics. Remaining sugar on fermented milk product includes the amount of prebiotic that will be used as carbon source in colon. Combination of potential probiotic L. rhamnosus R23 and mixture of inulin:GOS (1:9) could be used to make sinbiotic fermented milk product.   Key words: lactic acid bacteria, prebiotic, inulin, FOS, GOS

MODIFIKASI PATI GARUT  (Marantha arundinacea) DENGAN PERLAKUAN SIKLUS PEMANASAN SUHU TINGGI-PENDINGINAN ( AUTOCLAVING-COOLING CYCLING)  UNTUK MENGHASILKAN PATI RESISTEN TIPE III [Arrowroot (Marantha arundinacea) Starch Modification Through Autoclaving-Cooling Cycling Treatment to Produce Resistant Starch Type III] Sugiyono1), Ratih Pratiwi2), dan Didah Nur Faridah1) 1) Dosen Departemen Ilmu dan Teknologi Pangan, Fakultas Teknologi Pertanian-IPB 2) Alumni Departemen Ilmu dan Teknologi Pangan, Fakultas Teknologi Pertanian-IPB Diterima 3 September 2008/Disetujui  14 Juni 2009   ABSTRACT   The objectives of this research were to modify arrowroot starch to produce resistant starch type III by autoclaving-cooling cycling and to characterize the modified arrowroot starches according to their chemical properties. The research consisted of three steps : arrowroot extraction, starch modification, and chemical characterization. The extraction of arrowroot produced 10.78% starch. Starch modification by autoclaving-cooling cycle(s) was run in 6 different treatments with the aim of observing optimal yield of resistant starch. Resistant starch (RS) was produced through 1, 3, 5 cycle(s) of autoclaving-cooling treatment with different gelatinization periods (15 and 30 minutes autoclaving) for each cycle. Properties analyzed were starch digestibility, fat content, protein content, resistant starch content, and dietary fiber content. Native starch and commercial RS type III (Novelose 330) were also analyzed as a comparison.   Based on the starch digestibility, modified starch from 5 cycles, 15 minutes gelatinization period had the lowest digestibility while modified starch from 3 cycles, 15 minutes gelatinization period had no significant difference with commercial RS type III. Those two modified starches, native starch, and Novelose 330 were chosen for further chemical analysis. The fat content and protein content of the four samples were below 1% (db). Low fat and protein content were required to optimize the RS yield. The modification treatment  increased the dietary fiber content. The RS content of native starch, Novelose 330, modified starch 3 cycles, 15 minutes gelatinization period, and modified starch 5 cycles, 15 minutes gelatinization period were 2.12% (db), 20.80% (db), 10.91% (db), and 12.15% (db), respectively. It means that repeating autoclaving-cooling cycling could increase RS yield up to 6 times.                     Key words : arrowroot, resistant starch, starch modification, autoclaving-cooling
