Abstract This study aims to obtain the formulation of yellow sweet potato flour, goroho flour and red kidney bean flour in making the right flakes in terms of physicochemical characteristics, sensory characteristics and to calculate the calorific value of flakes. This study uses a completely randomized design with the comparison of yellow sweet potato: goroho plantain: red kidney bean is A = 50% + 40% + 10%; B = 60% + 30% + 10%; C = 70% + 20% + 10%; D = 80% + 10% + 10%. The parameters tested were chemical properties (moisture content, ash content, protein, fat, carbohydrate and crude fiber), calories, physical properties (color, fracture and crisp resistance in milk) and sensory properties (color, taste, aroma and texture). The best flakes in terms of their chemical composition were formulation A (50% yellow sweet potato flour + 40% goroho flour + 10% red kidney bean flour). Flakes that have the best physical properties are formulation C (70% yellow sweet potato flour + 20% goroho flour + 10% red kidney bean flour). The formulation of flakes which is most preferred by panelists is formulation C (70% yellow sweet potato flour + 20% goroho flour + 10% red kidney bean flour). The total number of calories in flakes ranges from 290,35 â€“ 342,51 Cal.Keywords: Flakes, yellow sweet potato, goroho plantain, red kidney bean

ABSTRACTSuryanto et al., 2011. Effect of callamansi citrus (Citrus microcarpa ) on chemical composition and antioxidantphytochemical of Goroho (Musa spp.) banana flour.The objective of this research was to study chemical composition and measured antioxidant activity of gorohobanana flour which immersed with callamansi. The goroho banana was soaked with water, callamansi andsodium methabisulfit for 60 minute. Furthermore, each flour were analyzed its phytochemical such as,proximate analysis, total phenolic content, flavonoid, condensed tannin, carotenoid, ascorbic acid, totalantioxidant using titration and spectrophotometer method. The results showed that callamansi addition of 1%was the best treatment for banana flour. The product had content of moisture, ash, fat, protein, fiber andcarbohydrate were 4.29 Â± 0.01; 3.74 Â± 0.02; 3.03 Â± 2,04; 1.47 Â± 0.57; 4.75 Â± 0.57 and 85.70 Â± 0.59,respectively.

Ethanol and acetone were used to extract phenolic components from corncob IDF powder with extraction time (30, 60, 90, 120, 150 and 180 min) in an ultrasonic bath (Krisbow 42 kHz, 50 watt). The both extracts were evaluated on the phenolic content and antioxidant activity with spectrophotometry method. The results of the phenolics content expressed in Î¼g/mL of gallic acid equivalent showed that ethanol extract has highest phenolic content compared with acetone extract of all the extraction time. The radical scavenging activity of extract ethanol exhibited strong than acetone extract of all extraction time tested. The result also showed that the ethanol extract has highest the total antioxidant capacity compared with acetone extract at all extraction time. This result suggest that corncob IDF powder especially the ethanol extract are very rich in phenolic component which is potential as antioxidant dietary fiber.Keyword: corncob, dietary fiber, ultrasonic, extraction time, phenolic, antioxidant

Corn cobs were extracted sequentially assisted by ultrasonication with ethanol and acetone solvents for 60 minutes to obtain free phenolic extract. The residue from free phenolic extraction was hydrolyzed with 2 M NaOH and neutralized and extracted with ethyl acetate to obtain bound phenolic extract. The three extracts were analyzed for total phenolic content and evaluated for antioxidant activity and inhibitory activity of AGEs formation. The total phenolic content of bound phenolic extract (EFT), acetone-free phenolic extract (EFBA) and ethanol-free phenolic extract (EFBE) were 288,39; 100,32 and 92,95 Î¼g/mL expressed as gallic acid equivalents, respectively. EFT extract showed higher DPPH free radical scavenging activity and total antioxidants more than EFBA extract and EFBE extract. Anti-glication of EFT, EFBA and EFBE were 61,93; 64,42 dan 66,31%, respectively. These result concluded that the EFT extract from corn cobs contains compounds having antioxidant properties and potential as anti-glication.
