“…Results of laboratory analysis of inulin levels in rough inulin were 8.523 -8.917%. This inulin level is still relevant to the levels of inulin studied by Kosasih et al (2015) which obtained inulin levels of 6.0-9.5% (w / w).…”

“…Inulin from the dahlia tubers has better quality than chicory and artichoke because it contains 72% inulin (At Tachriirotul, 2011). The inulin of dahlia tubers has been studied by several previous researchers such as, Kosasih et al (2015) who did extraction by using ethanol solvent. The results show that the best ratio of tubers dahlia and ethanol is 1: 2.…”

Isolation of inulin from starch generally is done by extraction method. The size of the material to be extracted will affect the extraction process performance. In laboratory scale, the size reduction was done with a knife and the separation of starch from tubers was done by juicer. Temperature fluctuations during the extraction process would affect the yield of inulin, hence juicers and waterbath were found ineffective for larger scale. This research was aimed to design an extractor equipped with agitator blades for size reduction and a temperature controller. Extractor performance was investigated by evaluating agitation time (60-150 minutes), distance between agitator blades on the shaft (5 and 7 cm), number of the agitators, (1, 2, and 3 blades) against the fineness of cut material, starch and inulin content. The results showed that the highest fineness of the samples was achieved at a distance of agitator blade of 7 cm, with 3 agitator blades and agitating time of 150 minutes. The highest yield of starch was 11.7% at size reduction time of 120 and 150 minutes using 3-blades agitator and the distance of 7 cm. The content of crude inulin obtained were by using the extractor was 2.206% and 2.213% by using the water bath. The difference of inulin content was 0.007% so it suggests that the extractor designed in this study can be used on inulin production in larger scale. The efficiency of the extractor was 85%.

Cookies merupakan salah satu makanan ringan yang disukai disemua kalangan umur. Umumnya cookies terbuat dari tepung terigu, memiliki kandungan karbohidrat dan lemak yang tinggi namun mengandung kadar serat yang rendah. Pada penelitian ini tepung umbi dahlia digunakan sebagai substitusi tepung terigu untuk pembuatan cookies kaya serat. Tujuan dari penelitian ini adalah untuk mengkaji penggunaan tepung umbi dahlia sebagai substitusi tepung terigu dan konsentrasi baking powder dalam formulasi pembuatan cookies. Rasio tepung umbi dahlia dan tepung terigu pada penelitian ini yaitu 15:85, 30:70, dan 45:55; dan konsentrasi baking powder yang digunakan yaitu 1–3% dari berat tepung. Metode Derringer’s Desirability Function digunakan untuk mendapatkan formula terbaik, dengan membandingkan kedekatan nilai karakteristik fisik cookies yang diberi perlakuan dengan karakteristik fisik cookies kontrol sebagai target. Hasil penelitian ini didapatkan formula terbaik untuk pembuatan cookies kaya serat adalah penggunaan rasio tepung umbi dahlia dan tepung terigu sebesar 30:70 dan penggunaan baking powder konsentrasi 3% dengan nilai total desirability (D) sebesar 0,87. Kesimpulan dari penelitian ini adalah cookies kaya serat berhasil dapat diproduksi dengan menggunakan tepung umbi dahlia dan jumlah penambahannya yang terbaik, dapat ditentukan.Effect of Substitution of Wheat Flour with Dahlia Tuber Flour and Concentration of Baking Powder on Physical Properties of Fiber Rich CookiesAbstractCookies are one of the snacks favored by wide range of consumers’s age. Usually, cookies made from wheat flour, which have high content of carbohydrate and fat but low content of fiber. In the present study, dahlia tuber flour was used to substitute wheat flour to produce fiber rich cookies. The effect of dahlia tuber flour was analyzed in the a varied baking powder addition. Dahlia tuber flour and wheat flour at ratio of 15:85, 30:70, and 45:55 (w/w); and baking powder concentration of 1–3% from total weight of the flour was usedas formula. Optimum formulation was obtained by Derringer’s Desirability Function, which compares the relation value of the physical properties of cookies made with dahlia tuber flour and control cookies which was made of wheat flour. The result showed that optimum formula to produce fiber rich cookies was obtained on the ratio of 30:70 and baking powder at concentration of 3%, with total desirability (D) value of 0.87. As conslusion, high fiber content cookies was succsessfully produced and the best dahlia tuber flour addition was determined optimally.
