EVALUASI NILAI GIZI PATI RESISTEN PADA PRODUK KERUPUK DARI EMPAT JENIS PATI [Nutritional Evaluation of Resistant Starch of Crackers Made of Four Kinds of Starch]
No full textIn this research, resistant starch content of crackers (=kerupuk) made of corn starch, cassava starch, sago starch and mungbean starch has been studied. Nutritional evaluation of crackers was conducted in experimental rats. It was found that starch content, amylose content and resistant starch content of sago starch were the highest, while those of mungbean starch were the lowest.Bioassay with rats revealed that starch flour diets had no effect on the water content of digesta, but these diets increased the weight, volume, concentration and pooled of the short chain fatty acid (SCFA) of digesta and decreased pH of digesta especially in rats fed sago crackers. Molar ratio of acetate and propionate were highest in rats fed sago crackers, while molar ratio of butyrate was highest in rats fed cassava crackers, therefore it has positive effect on human colon health
SIFAT FUNGSIONAL PRODUK INTERAKSI FRAKSI GLOBULIN 7S KOMAK (Dolichos lablab) DAN GUM XANTAN [Functional Properties of the Interaction Product Between Globulin of 7S Fraction of Lablab Bean (Dolichos lablab) with Xantan Gum]
No full textLablab bean (Dolichos lablab) seeds is a potential source of protein globulin.The bean’s protein content is 20.86 %, and the amount of globulin was more than 60% from the total protein, having major fractions of 7S and 11S. The objectives of this research were to explore the 7S globulin fractions, to study interaction between 7S globulin fractions with xanthan gum, and to observe the functional properties of the product of the interaction. The research was conducted in 2 steps. The first step was to fractionate the 7S fractions from globulin. The second steps was to interact 7S globulin fraction with xanthan gum. The yield of these interaction were examined for its physicochemical and functional properties. The results showed that the 7S globulin fractions could be interacted by xanthan gum at pH 7. The interacted product of globulin 7S fraction 10 % with xanthan gum 0,75 % had good functional properties than globulin 7S fraction, such as oil holding capacity, foaming capacity, and emulsion activity. Water holding capacity could not be detected because the yield became soluble. However,the foaming and emulsifying stability were still lower than those of soybean protein isolates. The research concluded that xanthan gum could be used to improve the physicochemical and functional properties of globulin 7S fraction
SIFAT FISIKO KIMIA BERAS MERAH GOGO LOKAL ENDE [The Physico-chemical Properties of Local Ende High Land Brown Rice]
No full textTen strains of Ende high land brown rice were assessed to underpin their physico-chemical properties related to their potential uses. Are Ndota has bigger grain size and smoother gel consistency than others (63.50 mm gel length). It potentially can be used as food thickeners and baby foods. Are Kea showed the highest water imbibition ability (90.99%), the fastest wettability (12.11 sec), and the highest dispersibility value (2,50 %) due to its high amylose content (33.21 %). Potentially, Are kea can be used for noodles. The variety also had small repose angle (27.46°), therefore it can be easily transported
