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.

Abstract

Orange-fleshed sweet potato (Ipomoea batatas) carotenoids were encapsulated in maltodextrin and whey protein concentrates by spray-drying to promote dispersibility in water and looked for the best encapsulant concentration in both encapsulants. The moisture content, wettability, hygroscopicity, color characterization, cold water solubility, and encapsulation efficiency were analyzed for encapsulant concentration of 10%, 20%, and 30% (w/v). The encapsulant concentration of 20% showed the best result with 6.09% moisture content, 11.07 hygroscopicity, 51 s wetting time, 94.50% cold water solubility, and 81.52% encapsulation efficiency for maltodextrin encapsulant. While whey protein concentrates encapsulant gave the result of 6.35% moisture content, 12.44% hygroscopicity, 148.8 s wetting time, 93.13% cold water solubility, and 82.02% encapsulation efficiency. The diffractogram from XRD showed that microcapsule had the amorphous phase dominant and indicated high solubility in water matrix. The microcapsule using maltodextrin encapsulant has smoother and more spherical morphology than microcapsule using whey protein concentrate encapsulant. The color characterization of 30% was lighter, less red, and less yellow than the others based on L*, a*, and b* value respectively. The carotenoid with 20% encapsulant concentration was well encapsulated enough and the addition of more than that did not produce significantly better results.

Abstract

The quality of coffee is strongly affected by its aroma, so that instrument for aroma testing is necessary especially for quality control. In this research, coffee aroma was tested using electronic nose and then correlated to gas chromatography-mass spectrometry (GC-MS). The green beans of robusta coffee (coffee canephora var.robusta) originated from Sumatra was used as a testing sample. The roasting temperature was varied to be 180 °C, 195 °C, and 210 °C, while the roasting time was set to be constant at 20 minutes. After the roasting process, the coffee beans were grounded using a coffee grinder. The feature of the response signal for each gas sensors of the electronic nose to ground coffee aroma, was extracted using two methods; i.e. gradient multiplied by signal peak and average value. The principle component analysis (PCA) was applied to discriminate the aroma of ground coffee with varied roasting temperature. The scoreplot of PCA analysis shows a clear discrimination of each coffee aroma, produced by different roasting temperature. From the GCMS analysis, it is clearly confirmed that more aromatic compounds detected when the roasting temperature increase. It is correlated with the discrimination result using electronic nose. The loading plot interpretation provides information that TGS822 and TGS826 are the most affecting sensors for discrimination of coffee aroma with varied roasting temperature. In the future, the electronic nose is potentially applied in coffee industry for quality control during process.

Abstract

Ultrasound-assisted cold brew (UACB) method emerged as a solution of a long brew traditional cold brew method in coffee. Apart from the particular taste and odor, cold brew coffee contains a number of phenolic (TPC), flavonoid compounds (TFC), and caffeine. The level of these compounds in the drinks is strongly influenced by various factors related to extraction process, such as extraction temperature (x1: 4 and 25 °C), time (x2: 5,15, and 25 min), UAE duty cycle (x3: 20, 50, and 80 s-1), and grind size (x4: coarse and medium). Based on the TPC, TFC, and caffeine contents, the optimum condition was at 25 °C for 25 min with 80 s-1 UAE duty cycle and medium coffee grind size: with 2.40 ± 0.11 mg GAE/mL, 1.69 ± 0.05 mg RE/mL, and 1.10 ± 0.02 mg caffeine/mL, respectively. Compared with the traditional cold brew method, only the TPC and caffeine content were significantly lower than the UACB method (p < 0.05). Furthermore, the TPC and TFC were stable in 7-day refrigerator storage (p > 0.05). The IC50 values of UACB coffee were 7,487 mg/L for DPPH assay and 64,113 mg/L for ABTS assay.
