Judul: Peningkatan Nilai Gizi Mi Basah dengan Fortifikasi Cabai Merah dan Kunyit
Abstrak: Noodles is a food product made from flour dough as the main ingredient. Various innovations and development is needed to improve nutrient quality of noodles. This study aimed to improve the nutritional value of noodles by adding chilli pepper and turmeric into the dough. The parameters analyzed were water, ash, fat, protein, fiber, carbohydrate, mineral (calcium and iron), and vitamin C contents as well as the antioxidant activity. The results were compared with control noodles (without fortification). Proximate analysis showed an increase in crude fiber content with addition of chilli pepper and turmeric, 0.2 and 0.3%, respectively. Addition of chilli pepper increased the iron content 1.9%. The vitamin C content in chilli pepper noodle increased 3 times compared with the control noodles. Best antioxidant activity was shown by the chilli pepper noodle product as well. Based on these results, it can be concluded that noodles fortified with chilli pepper improved nutritional values better than turmeric, especially iron and calcium mineral, vitamin C, and antioxidant activity

Judul: Formulation and Characteristics Determination of Dried Noodle from Porang Flour and Tapioca Starch with the addition of Spirulina platensis
Abstrak: Mi kering pada umumnya terbuat dari tepung terigu yang diperoleh dari hasil penggilingan biji gandum. Kebutuhan gandum di Indonesia dipenuhi melalui impor. Substitusi tepung porang dan tapioka sebagai sumber pangan lokal dengan penambahan spirulina dapat meningkatkan kandungan gizi dan senyawa bioaktif pada produk akhir mi kering. Penelitian ini bertujuan menentukan formula mi kering terbaik dari tepung porang dan tepung tapioka dengan penambahan Spirulina platensis melalui uji hedonik dan untuk menentukan karakteristik fisik, proksimat, dan fitokimia dari formula mi kering terpilih. Perlakuan yang digunakan dalam penelitian ini adalah penambahan konsentrasi spirulina sebanyak 1%, 2%, dan 3% ke dalam formulasi. Formula mi kering terpilih adalah penambahan konsentrasi spirulina 3% dengan nilai kadar air sebesar 10,56%, protein 1,95%, abu 0,63%, karbohidrat 83,29%, lemak 3,58%, serat pangan 19,93%, cooking loss 3,88%, daya rehidrasi 306,63%, elongasi 173,33%, dan nilai L* 35,99. Hasil uji fitokimia diperoleh mi kering spirulina terdeteksi mengandung alkaloid, flavonoid, dan fenol., Dry noodles are commonly prepared using wheat flour, obtained from milling wheat grain. Indonesia relies entirely on imports to meet its wheat demand. The substitution of konjac flour and tapioca as local food sources with the addition of spirulina can increase the nutritional content and bioactive compounds in the final dry noodle product. The aim of this study was to determine the best dry noodle formulation from konjac flour and tapioca flour with the addition of Spirulina platensis through hedonic tests and to determine the physical, proximate, and phytochemical characteristics of the selected dry noodle formulas. The treatment used in this study was the addition of 1%, 2%, and 3% spirulina concentrations into the formulation. The selected dry noodle formula is the addition of 3% spirulina concentration with a value of 10,56% moisture content, 1.95% protein, 0.63% ash, 83.29% carbohydrates, 3.58% fat, 19.93% dietary fiber, 3,88% cooking loss, 306,63% rehydration power, 173.33% elongation, and L* value 35,99. The results of the phytochemical test showed that spirulina dried noodles were detected to contain alkaloids, flavonoids, and phenols.
