Abstract

The efforts to diversify food products can be done by substitution of wheat flour with corn flour on instant noodle. Protein content of corn flour is low, so it is added with mungbean flour. The aim of this research was to increase protein content of instant noodle by substitution of corn flour with addition of 0-20% mungbean flour and to evaluate the physical, sensory and chemical properties of instant noodles. This study was preceded by a reduction phytate content on mungbean flour with boiling and soaking. Ratio of wheat flour and corn flour as control of 8:2. The addition of mungbean flour of 0%, 5%, 10%, 15% and 20%. Instant noodles were analyzed for physical, sensory and chemical properties. The result show that boiling treatment of mungbean decreased the phytate content higher than soaking treatment. Rehydration capacity, expansion ratio, flavor, elasticity of instant noodles with added of soaked mungbean flour of 5-20% and boiled mungbean flour of 5-10% same as control instant noodles. Instant noodle with added of soaked mungbean flour of 20% was able to increase protein content 1.38 fold with protein content 13.14% db, while with added of boiled mungbean flour of 10% was able to increase protein content 1.13 fold with protein content 10.82% db. Keywords : instant noodle; wheat flour; corn; mung bean; protein

Abstract

Low daily calcium intake in Asia, especially in Indonesia, is still a serious problem. The abundant fish bone waste from the fishery fillet industries in Indonesia,  can be employed as an alternative source of calcium to meet daily calcium needs. This research aimed to determine which of the six fish species (tilapia, catfish, grouper, snapper, tuna, kingfish mackerel) produces the best quality and the most cost-effective nano-calcium powder for a recommendation to the stakeholders. The calcium was extracted using an alkali treatment. The properties of the produced nano-calcium powders were analyzed for: proximate composition, calcium and phosphorus levels, color brightness level, XRD, FTIR, particle size, and SEM-EDX image analysis. The tilapia bone had the finest particle size of calcium (87.37 nm), while the grouper bone had the biggest particle size (281.4 nm). The brightness of all yields varied from 83.83 (beige-kingfish mackerel) to 90.64 (white-tilapia). The average calcium content from EDX analysis varied from 21.51% (snapper) to 34.37% (grouper). The average phosphorus levels ranged from 10.73% (kingfish mackerel) to 15.99% (grouper). The EDX Ca/P molar ratio was 1.41-1.66 across all samples. The FTIR spectra showed that all samples contained PO, CH, CO, NH, and OH groups. The XRD spectra pattern determined that the two main components of the fish bone nano-calcium powder were 90% hydroxyapatite and halite. All fish bone samples have the potential to be used as raw material for nano-sized calcium. However, grouper bone with the highest calcium content and the highest nano-calcium yield was the best choice for further study.
