The objective of this research was to determine total antioxidant activities ( FRAP and DPPH assays) and polyphenol compounds in 4 snack products i.e. loaf-bread, puifai (Thai steamed cupcakes), peakpoon (Green coconut sweet pudding) and snow skin mooncake fortified with 10% mulberry leaf powder from “ Buri Rum 60” cultivar. The result showed that antioxidant activities and polyphenol contents increased in 4 products fortified with mulberry leaf powder. Ferulic acid was the only phenolic compound found in all original products. Kaempferol, quercetin and caffeic acid were significantly increased, whereas ferulic acid was reduced in the modified formulas. Therefore, these bioactive compounds properties of mulberry leaf powder suggested their possible use for fortifying the healthy foods.Rajamangala University of Technology Phra Nakho

Get PDFวารสารวิชาการและวิจัย มทร.พระนคร, ปีที่ 14, ฉบับที่ 2 (ก.ค.-ธ.ค. 2563), หน้า 122-134A simple flow injection analytical system for an automatic determination of phosphate in water samples using the molybdenum blue method was developed. Samples were injected and mixed with ascorbic acid used as a reducing agent. The absorbance of the resulting molybdenum blue complex was measured at 880 nm by a spectrophotometer. The optimal conditions of this system were 2 mL/min of carrier flow rate, 1,000 μL of sample volume, 60 centimeters of mixing tube length, and 0.020 mol/L of ascorbic acid. The proposed method showed reliability, high sensitivity, spend small amount of reagents and samples, and fast sample throughput (52 samples/hour). The limit of detection (LOD) was 0.015 mg P/L of phosphate. Precision obtained injecting a phosphate standard solution of 0.50 mg P/L (n=10) was 1.81%. This system can be applied to determination of phosphate content in surface water samples in Lopburi province by comparing with a standard method. It was found that obtained from the developed system agreed well with the standard method using the pair t-test (tstat 0.04 < tcrit 2.36). This flow injection analysis system has no effect from arsenate and silicate interference for the analysis of natural water samples.Rajamangala University of Technology Phra Nakho

Get PDFวารสารวิชาการและวิจัย มทร.พระนคร, ปีที่ 14, ฉบับที่ 2 (ก.ค.-ธ.ค. 2563), หน้า 160-172Deterioration of reinforced concrete deep beam structure caused by chloride is severe andtakes up wide area even though the structure is not exposed to sea water or brackish water. Even the structure which is far from sea water or brackish water is affected by this problem.When the reinforced concreate deep beam structure is affected by chloride, steel reinforced inside the structure is corroded resulting in reducing the cross-sectional area of the reinforced steel affecting load capacity, deflection and beam failure. If there is no repair or strengthening, such capabilities are continuously reduced until it is no longer safe to use the beam. Therefore, it is necessary to repair or strengthening the deteriorated structure to be safely used. This research investigated strengthening of deteriorated reinforced concrete deep beam caused by chloride with 4 formats of carbon Fiber sheets to seek guidelines for the most efficient strengthening. The resultshowed that the strengthening by the 4 format of carbon fiber sheet could increase ultimate loadcapability yet could not improve ductility of the deteriorated beam to become close to the beamthat is not deteriorated. The strengthening that could increase the maximum ultimate load capability was the table format strengthening. In addition, the strengthening that the carbon fiber making 45 degrees with the length of the beam could best prevent diagonal cracks.Rajamangala University of Technology Phra Nakho
