dc.description | Umbi-umbian merupakan bahan berkarbohidrat tinggi, tetapi di Indonesia belum semua umbi-umbian dimanfaatkan dan dikembangkan, antara lain ganyong, suweg, ubikelapadan gembili. Altematif pengembangan umbi-umbian yaitu untuk tepung umbi, tepung pati dan tepung komposit. Penelitian evaluasi karakteristik sifat fisiko-kimia tepung umbi dan tepung pati ganyong, suweg, ubikelapa dan gembili dilakukan di Laboratorium Enzimatis dan Biokimia Balitbio Bogor. Analisis yang dilakukan adalah rendemen pati dan tepung, ukuran granula, derajat putih, daya serap air, proksimat, amilosa, dan sifat amilografnya. Hasil penelitian menunjukkan bahwa ganyong, suweg, ubikelapa, dan gembili mempunyai kadar pati yang tinggi berkisar 39,36-52,25%. Kandungan lemak (0,09-2,24%), dan protein (0,08-6,65%) pada tepung umbi dan tepung pati dapat meningkatkan manfaat tepung dan pati tersebut sebagai tepung komposit. Ganyong dan ubikelapa mempunyai ukuran granula pati lebih besar (22,5 dan 10 um). Tepung suweg mempunyai absorbsi air maupun minyak tertinggi (2,69- 4,13 dan 2,34-2,98 gIg). Hasil rendemen menunjukkan bahwa ganyong lebih prospektif dikembangkan untuk produk tepung patio Suweg dan gembili mempunyai prospek untuk produk tepung umbi maupun tepung pati sedangkan ubikelapa untuk tepung umbi. Sifat fisikokimia ganyong dan suweg mempunyai amilosa rendah (18,6% dan 19,2%) dan viskositas puncak tinggi (900-1080 BU dan 780-700 BU). Implikasi hasil penelitian untuk menggali potensi sumber karbohidrat sebagai tepung komposit ataupun sebagai bahan industri perpatian Physicochemical characteristic of flour and starch from Canna, Amorphophallus and DioscoreaIn Indonesia roots and tubers are carbohydrate source, but many kinds of them are not optimally utilized, as well as canna, Amorphophallus campanulatus BI, Dioscorea alata, and Dioscorea esculenta. Alternative products from these roots and tubers are flour, composites flour and starch. Research on physicochemical properties of roots and tubers was carried out in Laboratory of Enzyme and Biochemistry at Research Institute of Agricultural Biotechnology, Bogor. Analysis of flour and starch included yield of flour and starch, water and oil absorbsion, size of starch granule, the whiteness, proximate analysis, amylose content, and starch paste characteristic. The result showed that these roots and tubers have high content of starch (39,36-52,25%). Lipid and protein content (0,09-2,24% and 0,08-6,65% respectively) in flour and starch increased usefullness as raw materials of composite flour. Canna and Dioscorea alata have a large size granula starch (22,5 and 10 um), Flour of Dioscorea esculenta has the highest water and fat absorbtion (2,69-4,13 and 2,34-2,98 gIg respectively). Based on yield of flour or starch, canna is more feasible to produce starch. Amorphophallus campanulatus BI and Dioscorea esculenta are good raw material to produce starch and flour. Dioscorea alata is feasible for flour only. Starch of Canna and Amorphophallus campanulatus BI have low content of amylose (18.6% and 19.2%) and high peak viscosity (900-1080 BU and 780-700 BU). | en-US |
