หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Antioxidants on Properties of Rice Flour/Cassava Starch Film Blends Plasticized with Sorbitol) ผู้เขียน: Pornchai Rachtanapun, Wirongrong Tongdeesoontorn สื่อสิ่งพิมพ์:pdf AbstractThe effects of antioxidants (gallic acid (GA), propyl gallate (PG) and butyl hydroxyanisole (BHA)) on the mechanical properties, water solubility and melting point temperature (Tm) of rice flour/ cassava starch film blends with sorbitol were investigated. All films forming a solution were casted and dried at room temperature. Film blended with GA (400 mg) showed higher tensile strength and folding endurance, but lower %elongation than the control film blend. The tensile strength of film blended with PG and film blended with BHA were not significantly different (p>0.05) compared with the control film. Film blended with GA showed higher water solubility than the control film, film blended with PG and film blended with BHA, respectively, because GA had a higher polarity than PG and BHA, respectively. Differential scanning calorimeter (DSC) thermographs showed a single peak for all film blends with and without antioxidants, confirming their homogeneity. Changes in the Tm of film blends with antioxidants depended upon the Tm of the antioxidants. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Caloric Reduction in Mungbean Conserve Filling of Flaky Chinese Pastry) ผู้เขียน:Teeranuch Chysirichote, อัญชนีย์ อุทัยพัฒนาชีพ, ดร.วารุณี วารัญญานนท์ สื่อสิ่งพิมพ์:pdf AbstractThis research aimed to develop reduced-calorie fl aky Chinese pastry by reducing the oil and sugar contents. Inulin solution (I) was used as a fat replacer combined with sorbitol (Sor) or maltitol (Mal) solution as a sugar replacer in mungbean conserve fi lling. The factorial completely ramdomized design experiment involved reducing the oil (RF) level by 0, 25, 50 and 75% of the oil weight and sugar (RS) level was reduced by 0, 10, 20 and 30% of the sugar weight. The results showed that the scores for all characteristics tested except for the bean odor of RF25/RS0 (25% fat reduction combined with 0% sugar reduction) were not signifi cantly different from RF0/RS0 (P > 0.05). Then, inulin solution at levels of 80, 90 and 100% (w/w) were combined with sorbitol or maltitol solution at levels of 10, 20 and 30% (w/w). These combinations respectively replaced the oil and sugar in the RF25/RS0 formula. The hardness of the pastry signifi cantly increased as the level of replacement of the fat and sugar increased. However, the overall liking of the pastry from the I80/Mal10 formula was at the moderate level which was not signifi cantly different from RF25/RS0 (P > 0.05). In addition, the fat and energy contents of the I80/Mal10 formula decreased by 69.44 and 25.51%, respectively from those of full-fat formula. Furthermore, the amounts of cholesterol and total saturated fat were 1.57 mg and 1.69 g per serving size (30 g). This product could be claimed to be “reduced-calorie”, “reduced-fat” and “cholesterol-free”. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Characterization of the Sugar Utilization Gene polS from Ralstonia solanacearum) ผู้เขียน:ดวงแข กาญจนโสภา, นางสาวอรวรรณ (ยกเลิก) ชัชวาลย์การพาณิชย์ (ยกเลิก), ดร.ศรีเมฆ ชาวโพงพาง, ผู้ช่วยศาสตราจารย์ , ดร.วิชัย โฆสิตรัตน, รองศาสตราจารย์ , ดร.นิพนธ์ ทวีชัย, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe gene coding for sorbitol dehydrogenase (polS) from Ralstonia solanacearum strain TO 264 biovar 3 was cloned, sequenced, and compared to homologous sequences from the other bacteria. The result showed that the sorbitol dehydrogenase gene from R. solanacearum strain TO264 displayed the highest similarity to that of R. solanacearum GMI1000 with 99.6% amino acid similarity and the least similarity to sequence of Pseudomonas syringae pv. syringae with 56% amino acid similarity. Phylogenetic analysis of polS showed the Burkholderia cepacia sequence to join as sister to the R. solanacearum TO264 pair. Analysis of the deduced amino acid sequence revealed homology to enzymes of the short-chain dehydrogenase/reductase protein family. The eight amino acid residues were conserved in most of these proteins. These residues included the almost invariant tyrosine (Y) and lysine (K) residues of consensus sequence Y-X-X-X-K, which were essential for catalysis and were located in the active site in C-terminal whereas the glycine (G) residues of the G-X-X-X-G-X-G segment were characteristic of the NAD+ binding domain in the N-terminal region. The 771 bp of polS gene from R. solanacearum TO264 was subcloned into expression pGEX-2T vector. The polS ORF encoded a protein consisting 256 amino acid residues with estimated molecular mass of 27 kDa by SDS-PAGE analysis. |
