Abstract

Starch Noodles (SN) are produced from purified starch or combined flour from various plant sources. Sago starch is one of indigenous Indonesian flours that can be used for making SN. The physical characteristics that greatly affect the quality of rehydrated SN are cooking loss, elongation, hardness and adhesiveness/stickiness. Starch noodles have low of cooking loss but high hardness value, so it is less preferred. The purpose of this study was to obtain the optimum formulation of noodles made of sago with mung bean flour substitution. Formula optimization was done by using Mixture Design (DX7) with sago starch and mung bean flour as variables (80-100% and 0-20%; respectively). Mung bean flour substitution reduced hardness, adhesiveness and elongation of sago noodles, yet it increased the cooking loss. The best formulation based on physic-chemical characterization was SN with substitution of 4,7% mung bean flour. This sago noodles had 1996,03 gf hardness, -19,2 gf adhesiveness, 214,35% elongation and 10,82% cooking loss. Sensory test results for the most optimum formulation showed that the SN was not significantly different with those of commercial wheat noodle.ABSTRAKMi pati merupakan mi yang dibuat dari pati dan atau kombinasi tepung dari bahan non terigu. Bahan baku non-terigu indigenous Indonesia yang dapat digunakan untuk membuat mi pati adalah sagu. Karakteristik fisik yang sangat mempengaruhi kualitas mi setelah direhidrasi adalah cooking loss, elongasi, kekerasan dan kelengketan. Mi yang dibuat dari bahan dasar pati memiliki cooking loss yang rendah namun kekerasan yang tinggi, sehingga kurang disukai. Tujuan penelitian ini adalah mendapatkan formulasi optimum dari mi berbahan dasar sagu dengan substitusi tepung kacang hijau, sehingga dapat dihasilkan mi yang baik secara fisik dan diterima secara organoleptik. Optimasi formulasi dilakukan menggunakan Mixture Design (DX7) dengan variabel berupa persentase pati sagu (80-100%) dan tepung kacang hijau (0-20%). Substitusi tepung kacang hijau dapat menurunkan kekerasan, kelengketan, dan elongasi mi sagu, namun meningkatkan cooking loss. Produk optimum mi sagu diperoleh dengan substitusi tepung kacang hijau 4,7%. Pada kondisi ini mi sagu memiliki karakteristik kekerasan 1996,03 gf, skor kelengketan -19,2 gf, skor elongasi 214,35% dan skor cooking loss 10,82%. Uji sensori terhadap mi sagu formula optimum menunjukkan bahwa mi sagu yang dibuat secara keseluruhan tidak berbeda nyata dengan mi kering terigu komersial.

Abstract

The fatty acid composition of palm oil is the major factor influencing its physical and chemical properties. The purpose of this research was to evaluate the analytical performance of major fatty acids (palmitic acid, stearic acid, oleic acid, and linoleic acid) analysis in palm oil. Triglycerides of palm oil were derivatized to fatty acid methyl esters (FAMEs) by using boron trifluoride (BF3) in methanol. FAMEs were determined by gas chromatography-flame ionization detection (GC-FID) using DB-23 capillary column as stationary phase. The studied parameters were instrument performance analysis, the efficiency of fatty acid derivatization, stability of derivatized analytes, accuracy, repeatability, intra-lab reproducibility, ruggedness, and method uncertainty. The evaluation results showed the instrument linearity at a working range of 5 to 40 mg/mL marked by coefficient of determination (R2) between 0.991-0.995. Instrument limits of detection (LOD) and instrument limits of quantification (LOQ) for 4 major fatty acids analysis were 26-35 µg/mLand 86-128 µg/mL, respectively. The increase of fatty acid concentration led to the decrease of derivatization efficiency in the fatty acids analysis. The result also showed that derivatized analytes were stable during 24 h storage at freeze temperature. The average recovery values by spiking method with the spiking concentration at 50 and 90 mg/g sample were at 75-94 % for stearic and linoleic acids analysis, however those for palmitic and oleic acids analysis were considered very low (<40 %), due to their low derivatization efficiency. Repeatability and intra-lab reproducibility of 4 major fatty acids analysis were at acceptable ranges, 0.45-1.38 % and 1.15-2.03 %, respectively. Determination by varying the volume of derivatizing agent showed the rugged method. Uncertainty of repeatability (Ur) and uncertainty of reproducibility (Ur) were ranged at 1.84-9.02 mg/g and 1.40-10.65 mg/g, respectively. This method was considerably reliable for the analysis of less abundance fatty acids in palm oil, stearic and linoleic acids.

Abstract

The purpose of this study was to obtain the formula of sorghum rice analogue by mixed spices addition with acceptable sensory and physico-chemical characteristics.  The selection of sorghum rice analogue formula was tested by using hedonic test with 70 untrained panelists. The addition of mixed spices powder was as follows: 30 % onion, 20 % garlic, 10 % bay leaves, 20 % ginger and 20 % lemongrass. Those mixed spices powder were added to the sorghum rice analogue at percentage of 0.25 %, 0,5 %, 1 %, 2 %, 3 % and 0 % (control)  from total dough weight. The sorghum rice analogue was made using extrusion technology (a twin screw extruder). The overall sensory evaluation result showed that the addition of spice mixed had significant effect (p ≤ 0.05) on the characteristics of sorghum rice analogue. The panelists accepted the sorghum rice analogue with 1% mixed spice. The preferred formulation was the addition of 1% mixed spice which contain of  9.56 % moisture, 0.72 % ash, 0.53 % fat, 6.22 % protein, 92.53 % carbohydrate, 26.48 % amyloseand 6,67 % dietary fiber. Sorghum rice analogue enriched by spices is a potential as a rich fiber source.ABSTRAKTujuan penelitian adalah mendapatkan formula beras analog berbahan dasar sorgum dengan penambahan rempah campuran yang dapat diterima secara sensori. Pemilihan formula dilakukan dengan uji hedonik menggunakan 70 orang panelis tidak terlatih. Rempah yang ditambahkan berupa bubuk rempah campuran yang terdiri atas bawang merah 30%, bawang putih 20 %, daun salam 10 %, jahe 20 % dan sereh 20 %. Penambahan bubuk rempah campuran untuk pembuatan beras analog sorghum berturut-turut 0,25 %, 0,5 %, 1 %, 2 %, 3 % dan kontrol (tanpa rempah) dari total berat adonan diluar air.
