  • This study investigated the bread-making properties of rice bread supplemented with HPMC (hydroxypropyl methylcellulose) 1~3% and gluzyme (glucose oxidase), fungamyl (fungal ${\alpha}$-amylase) and pentopan (xylanase+hemicellulases) (0.0015~0.0090%). The viscoelastic properties of the dough with HPMC 1~3% were analyzed. When the rice flour was supplemented with HPMC 1~3%, the viscoelastic properties of the dough tended to increase as the amount of added HPMC was increased. The physicochemical characteristics of the rice bread with HPMC, gluzyme, fungamyl, and pentopan were analyzed. Supplementing the rice flour with HPMC, gluzyme, fungamyl, and pentopan had a significant effect on the volume (p<0.01) and specific volume (p<0.001) of the rice bread. Supplementing the rice flour with 3% HPMC and 0.0045% or 0.0090% pentopan had a significant effect on increasing the volume (p<0.01) and specific volume (p<0.001) of the rice bread. Supplementing the rice flour with 3% HPMC, 0.0023% gluzyme and 0.0015% fungamyl had a significant effect on increasing the volume (p<0.01) and specific volume (p<0.001) of the rice bread. These results suggest that supplementing the rice flour with HPMC, gluzyme, fungamyl and pentopan is effective for the production of rice bread.

  • This study investigated the baking properties of sorghum with the addition of xylanase or Pentopan, which is a baking additive containing xylanase. The control bread was made with a 30% substitution for wheat flour and the optimum level of enzyme addition was 0.75 mg/g flour for Pentopan and 5 mg/g flour for xylanase. The water binding capacity of wheat flour increased with the addition of sorghum, but decreased with the addition of either xylanase or Pentopan. The resistance of dough increased while extensibility decreased with the addition of sorghum; however, resistance decreased while extensibility increased with the addition of the enzyme. Specific volume of bread decreased significantly with the addition of sorghum. However, the specific volume was significantly recovered with the addition of enzyme. Crumb firmness was higher in the sorghum-added sample, but crumb firmness of the bread decreased with the addition of the enzyme. The crumb firmness of bread with added xylanase decreased significantly in 24 hours. These results demonstrated that adding sorghum with either xylanase or Pentopan that included xylanase increased specific volume and decreased crumb firmness whereas sorghum decreased the quality of fermented bread when added to wheat flour. The firmness rate of fermented bread particularly decreased with the addition of pure xylanase.

  • Enzymatic treatments of maize flour (MF) were investigated using commercial carbohydrases (Ultraflo L and Pentopan 500 BG) to enhance the phenolic acid content and antioxidant property. The total phenolic acid content of the MF was 3.76 mg/100 g, whereas those of the Pentopan 500 BG and Ultraflo L treated MF were 6.85 and 39.55 mg/100 g, respectively. Particularly, ferulic acid content of Pentopan 500 BG-treated MF was 20.0 times higher than that of untreated MF (1.7 vs. 33.9 mg/100 g). Pentopan 500 BG appeared to be more effective than Ultraflo L in increasing the free phenolic acid content. Antioxidant activities of enzyme treated MF were significantly higher than untreated MF. In particular, the Pentopan 500 BG-treated MF (16.0 mmol TE/100 g) was approximately 1.5 times higher than untreated MF (12.6 mmol TE/100 g). Enzymatic hydrolysis of cell wall polysaccharides in MF could be used as an effective procedure for not only increasing phenolic content but also antioxidant activities.

  • Brown rice flour (BRF) was treated with different carbohydrases (Viscozyme, Termamyl, Celluclast, AMG, Ultraflo, and Pentopan), and then aqueous alcoholic extracts (70% ethanol) from the treated RBF were examined for their phenolic compositions and antioxidant activities (ABTS and DPPH radical scavenging activity). All the carbohydrases tested induced significant increases in ABTS radical scavenging activity (2.1-3.0 times). Moreover, These enzymes increased the amount of extractable free phenolic acids by 10-15 times, especially for ferulic and p-coumaric acid. Among the enzymes tested, Pentopan which was active in arabinoxylan hydrolysis appeared to be most effective in increasing the free phenolic acid content and ABTS radical scavenging activity than other enzymes. Enzymatic hydrolysis of cell wall polysaccharides in BRF could be used as an effective procedure for raising the amount of extractable phenolic acids and thus increasing the antioxidant activity of BRF extract.

  • This study sought to optimize the extraction and enzymatic treatment conditions of Panax ginseng leaves, stems, and roots for the production of fermented ginseng. The optimization enhanced the extraction of total saccharide, a nutrient and growth-activating factor for Lactobacillus bacteria. The hydrolysis of ginseng leaves, stems, and roots was tested with eight enzymes (Pentopan, Promozyme, Celluclast, Ultraflo, Pectinex, Ceremix, Viscozyme, and Tunicase). The enzymatic hydrolysis conditions were statistically optimized by the experimental design. Optimal particle size of ginseng raw material was <0.15 mm, and optimal hydrolysis occurred at a pH of 5.0-5.5, a reaction temperature of 55-$60^{\circ}C$, a Ceremix concentration of 1%, and a reaction time of 2 hr. Ceremix produced the highest dry matter yield and total saccharide extraction. Ginseng leaves were found to be the most suitable raw material for the production of fermented ginseng because they have higher carbohydrate and crude saponin contents than ginseng roots.

  • The effects of cell lytic enzyme treatment on total phenolic content, antioxidant and antityrosinase activities of lotus leaf were investigated. The dried lotus leaves were hydroyzed by cell lytic enzymes such as Promozyme, Ceremix, Pectinex, Ultraflo, Celluclast, Pentopan, Tunicase, Viscozyme at their optimum pHs (pH 5-8) at $50^{\circ}C$ for 4 hrs. Depending on the enzymes used, total phenolic compounds content was measured as $1,079-1,476{\mu}g$/mL, and antioxidant activities and whitening activities were increased by 5~10% and 20%, respectively Among the tested hydrolytic enzymes, Promozyme (pullulanase) was selected as the most suitable enzyme for the extraction of total polyphenol from lotus leaf. The optimal dosage of Promozyme were found to be 1-2% (w/w). By Promozyme treatment, total phenolic compounds content of the lotus extract significantly increased compared to the extraction without enzyme treatment.
