Instant noodles gained widespread popularity, resulting in a surge in global wheat consumption. However, concerns about the health implications of wheat-based products spurred the need for alternative ingredients in noodle production. The substitution of wheat flour with local resources, such as mocaf flour, and the enrichment of noodles with latoh (Caulerpa lentillifera), provided an opportunity to reduce wheat imports while enhancing the quality and potential health benefits of noodles. This study aimed to determine the optimal formulation, assess the characteristics, and evaluate the functional properties of wheat noodles that were substituted with mocaf flour and supplemented with latoh. The formulation of these noodles was conducted using design expert. The research encompassed a comprehensive analysis of physical, chemical, and organoleptic properties. The presence of latoh, in terms of chemical characteristics, increased the water and protein content in the noodles. On the physical side, it increased the final viscosity, setback, peak time, and elongation, as well as reduced the peak viscosity and breakdown. Meanwhile, the presence of mocaf increased carbohydrate content, peak viscosity, and breakdown value. The variations in noodle formulas only affected consumer acceptance of the appearance of the noodles; the noodle formula 99:1 (Mocaf:Latoh) had the most preferred appearance. Based on the sensory test parameters, the elongation value, and the tensile strength, noodles with optimal formulas were obtained, namely mocaf 63%, wheat 36% and latoh 1%. The optimum formula was similar to sample 10 (60:39:1) which exhibited characteristics such as a bright color, a rather smooth appearance with no cracks, a very soft mouthfeel, a bit springiness and elasticity, and a slightly non-sticky texture to the teeth without a fishy aroma. The essential and non-essential amino acids with the highest concentration contained in the Mocaf Noodles’ optimum formula were glutamate and leucine. Mocaf noodles with added latoh had low fat content but high carbohydrates and were rich in essential amino acids compared to other noodles. Additionally, they possessed sensory characteristics that were deemed acceptable by the panelists.

Noodles are popular carbohydrate-rich food products generally made from wheat flour. This study developed a new type of noodle out of local resources namely sorghum flour, mung bean, and sago starch with the following formula variations: F1 (20:30:50), F2 (30:30:40), F3 (40:30: 30), F4 (50:30:20) and F5 (60:30:10). The nutritional and functional property of each formula then analysed. All formulas fulfilled the daily dietary intake recommendations, which contain approximately 9.64-11.83% protein, 0.17-0.33% fat, 86.76-88.74% carbohydrate, with total calories of 397-399 kcal/100 g. F1 has the highest dietary fibre content (13.16%), with 4.2% soluble dietary fibre (SDF) and 9.48% insoluble dietary fibre (IDF). The resistant starch content of all formulas was relatively high, between 16.35-21.57%. Based on the results of this study, sorghum flour, mung bean and sago starch flour-based noodles can be a good source of daily nutrition which also include functional compounds such as dietary fibre and resistant starch.

Foods with low glycaemic index (GI) are part of the functional aliments recommended for patients with diabetes mellitus. These foods can be produced from materials with high amylose and/or high dietary fibre content by using specific processing technologies that increase their resistant starch content. Here, analogue rice formulations were prepared using sago and red beans as main materials, employing extrusion technology. We determined their resistant starch (RS) content and GI to evaluate their potential as functional foods for diabetics. Six formulations were tested: pure sago analogue rice (BS100) and five sago analogue rices with the addition of 5, 10, 15, 20 and 25% red bean flour (BSKM5, 10, 15, 20 and 25, respectively). The GIs were determined for 20 healthy volunteers. RS contents of BS100, BSKM5, 10, 15, 20 and 25 analogue rices were 12.25, 11.80, 11.18, 10.97, 10.24 and 9.28%, respectively. The lowest GI value was obtained with BS100 (40.7), while BSKM5 and BSKM10 had GIs of 48.3 and 50.4, respectively. Analogue rice BSKM15 and 20 had medium GIs, 68.8 and 69.5, respectively and BSKM25 was included in the high GI category (76.5). Pure sago analogue rice (BS100) and analogue sago rice with red bean flour added up to 10% (BSKM5 and 10) were included within low GI category, making them potential functional foods for type 2 diabetics.

Corn silk is a by product or waste that is commonly used as a traditional medicine that contain bioactive compounds such as volatile oils, steroids, alkaloids, tannins, flavonoids, chlorogenic acid and phenolic compounds, containing protein, carbohydrates, minerals (Ca, Mg, Cu , Zn, Fe and Mn), higher crude fiber, vitamin B, vitamin C, vitamin K, steroids such as sitosterol and stigmasterol, alkaloids, saponins, tannins, flavonoids, anthocyanins, protokatekin, vanilic acid, derivatives hasperidin and quersetin, phenols, terpenoids and glycosides, maysin, β-carotene, beta-sitosterol, geraniol, hordenin, limonene, menthol and viteskin also a good source of poliphenol as antioksidan. Solvent used for the extraction of flavonoid compounds are methanol, ethanol, acetone and ethyl acetate. Basic separation by solvent extraction is the difference in the solubility of each composition in compaction with solvent. Solubility is influenced temperature, stirring speed, the extraction time, comprehensive tangent plane solids by solvent extraction and frequency.This study aims to extract corn silk by using a variation of solvent type in terms of yield, total phenols, flavonoids and antioxidant activity.The experimental design used in this study is completely randomized design (CRD) 1 factor with 5 replications. Solvent: methanol: water (85:15) (v/v) ethanol: water (85:15) (v/ v), ethyl acetate: water (85:15) (v/v), acetone: water (85 : 15) (v/v). Furthermore, the data obtained were analyzed variants and if there is a difference between treatments continued by Duncan Multiple Range Test (DMRT) at 5% level.Variations in the type of solvent significant (p <0.05) to the yield, total phenol, total flavonoids and antioxidant activity. Variations in the type of solvent with the highest yield at a ratio (methanol: water), and the ratio (ethanol: water), then the ratio (acetone: water) and the lowest ratio of (ethyl acetate: water). At ratio (methanol: water) obtained yield is 65.8%, total phenol ie 45350.27 mg / kg GAE, total flavonoids 291.28 mg QE / kg and activities of antioxidant that is 92.1%.
