Indikator wheat pollard sebagai prebiotik terlihat dari peningkatan kadar rafinosa, arabinosa dan resistan starch berturut-turut sebesar 0.72% menjadi 3.95%; 0.51% menjadi 1.04%; 0.51% menjadi 1.04% dan 5.28% menjadi 14.15%.  Kesimpulan penelitian adalah wheat pollard yang diautoclave selama 15 menit memberikan komposisi terbaik sebagai prebiotik.The objective of this study was to examine the long-term effect of warming wheat pollard by autoclave to obtain potentially prebiotic monomers. The study used a completely randomized design pattern in the same direction with 4 treatments and 4 replications. The parameters observed were water content, ash, crude fat, crude protein, crude fiber, extract without nitrogen, acid detergent fiber (ADF), neutral detergent fiber (NDF), cellulose, hemicellulose, lignin, gross energy, mannosa, arabinose, glucose, sucrose, raffinose, amylose, starch, amylopectin, resistance starch and wheat pollard profile through scanning electron microscope (SEM). The results showed that there was a treatment effect (p <0.05) on moisture, ash, crude protein, crude fiber, BETN, NDF, hemicellulose, lignin, cellulose, gros energy, raffinose, glucose, arabinose, sucrose, amylose, starch, amylopectin , resistance starch but in crude fat, ADF and mannose did not have a significant effect (p>0.05). The indicator of wheat pollard as a prebiotic is seen from an increase in raffinose, arabinose and resistance starch levels of 0.72% to 3.95%; 0.51% to 1.04%; 0.51% to 1.04% and 5.28% to 14.15%. The conclusion of the study was that wheat pollard which was autoclaved for 15 minutes gave the best composition as a prebiotic.","PeriodicalId":53087,"journal":{"name":"Jurnal Aplikasi Teknologi Pangan","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75626953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schott) adalah salah satu jenis tanaman umbi kaya karbohidrat yang berasal dari Kepulauan Siau, Manado, Sulawesi Utara. Kandungan pati daluga yang tinggi berpotensi sebagai bahan baku pembentukan pati resisten (Resistant starch/RS). Tujuan dari penelitian ini adalah meningkatkan kadar RS tepung daluga melalui modifikasi Heat Moisture Treatment/HMT dan fermentasi Bakteri Asam Laktat/BAL serta mengkaji pengaruh modifikasi terhadap sifat fisikokimia tepung daluga modifikasi. Penelitian terdiri dari 3 perlakuan antara lain HMT menggunakan oven (100 ̊C, 16 jam), autoklaf (121 ̊C, 60 menit), dan kombinasi fermentasi BAL dengan Lactobacillus plantarum BSL dan HMT. Berdasarkan hasil analisis, tepung daluga hasil modifikasi oven, autoklaf, dan Lactobacillus plantarum BSL + HMT memiliki kadar RS masing-masing sebesar 7,14; 8,81; 5,31% (db). Hasil modifikasi tepung daluga juga berpengaruh terhadap kadar serat pangan, amilosa, serta perubahan viskositas dan suhu gelatinisasi. Kesimpulannya, tepung daluga dengan modifikasi HMT dan fermentasi bakteri asam laktat dapat memberikan pengaruh yang bervariasi pada berbagai sifat fisikokimianya.Physicochemical Characteristics of Modified Daluga Flour (Cyrtosperma Merkusii. (Hassk.) Schott) by Lactic Acid Bacteria Fermentation and Heat Moisture TreatmentAbstractDaluga (Cyrtosperma merkusii. (Hassk.) Schott) is one of the tubers originated from the Siau Islands, Manado, and North Sulawesi. The starch contents of daluga which were quite and have the potency as raw materials for starch resistant (SR) formation. The objectives of this research were to increase the SR content of daluga flour, to obtain a modified flour with Lactic Acid Bacteria (LAB) fermentation and Heat Moisture Treatment/HMT of daluga flour and to examine the effect of HMT and LAB fermentation on physicochemical characteristics of daluga flour. The study consist of 3 treatments of HMT, i.e. oven (100°C, 16 hours), autoclave (121° C, 60 minutes), and combination of LAB fermentation by Lactobacillus plantarum BSL and HMT. The result showed the specific value of RS from oven, autoclaves and LAB treatment i.e. 7.14, 8.81, 5.31%, respectively. The results of modified daluga flour could affect dietary fiber, amylose contents, viscosity and gelatinization temperature. As conclusion, modified daluga flour with HMT treatment and fermentation might provide specific result on its physicochemical characteristics.","PeriodicalId":53087,"journal":{"name":"Jurnal Aplikasi Teknologi Pangan","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87375735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
