摘要:
A dough composition containing not less than 15 units of a raw starch decomposing enzyme per kilogram of a raw material to be baked, which may further contain glucose oxidase and/or hemicellulase. The characteristics of the dough composition are improved to provide baked products which have improved softness and are slow in getting hard.

A novel diglycosidase produced by a microorganism belonging to the genus Penicillium, having the following physicochemical properties:(1) action and substrate specificity: it acts on a disaccharide glycoside, releasing the disaccharide sugar and the aglycone thereof; (2) optimum pH: around 4.5; (3) pH stability: it is stable at pH 4.0 to 8.0 under the processing condition of 37° C. for 30 minutes, and retains its 80% or more of the activity even after processing at pH 4.0 or lower; (4) optimum temperature: around 60° C. in a sodium acetate-acetic acid buffer solution (pH 5.5); (5) thermal stability: it is stable at 50° C. or lower in a sodium acetate-acetic acid buffer solution (pH 5.5) and retains 45% of the activity even after processing at 60° C. for 40 minutes; (6) molecular weight: 40,000±5,000 Da based on SDS-PAGE measurement; and (7) isoelectric point (pI): about 4.3.
摘要:
A stencil screen platemaking apparatus for a heat-sensitive platemaking method, having a thermal head retaining frame to which a thermal head is attached arranged to oppose a platen roller retaining frame having a platen roller attached thereto, and a stepping motor, in a manner permitting contact and separation between the thermal head and the platen roller. In the separated state of the thermal head and the platen roller, an art work material is arranged between both retaining frames, so that the screen is pinched between the thermal head and the platen roller. Then, the platen roller is driven and revolved so that platemaking is performed in a state that the thermal head is maintained at a fixed position and that the art work material is moved.
摘要:
It is intended to provide an anti-inflammatory agent made from a highly safe material which can be daily taken as a food, an agent for preventing or ameliorating allergic diseases and a functional food having the above-mentioned effects. The anti-inflammatory agent contains an α-bond galactooligosaccharide as the active ingredient. The agent for preventing or ameliorating allergic diseases contains an α-bond galactooligosaccharide as the active ingredient. The functional food contains an α-bond galactooligosaccharide as the active ingredient. As such α-bond galactooligosaccharide, use can be made of a product synthesized by the dehydration condensation reaction by α-galactosidase with the use of galactose or galactose-containing substance as a substrate.
摘要:
An antioxidant material of the present invention contains flavonoid aglycon and vitamin C. The flavonoid aglycon is eriodictyol and/or diosmetin obtained by treatment of a raw material containing flavonoid glycoside derived from lemons, limes, or sudachis to form the aglycones thereof. It is preferred that this antioxidant material be produced through a step of mixing the flavonoid aglycon and the vitamin C after the treatment to form the aglycones. The treatment to form the aglycones is glycosidase treatment using a β-glycosidase derived from a microorganism of the genus Aspergillus or Penicillium multicolor, or microbial fermentative treatment using a microorganism of the genus Aspergillus. An anti-deterioration agent and a food or beverage of the present invention contain the antioxidant material.

Further provided is a method of producing a tea beverage having an improved flavor, with good productivity and stable quality. In the process of producing a tea beverage, a diglycosidase derived from a microorganism is allowed to act.
摘要:
This invention relates to a .gamma.-cyclodextrin glucanotransferase having novel properties, to a process for the production of the .gamma.-cyclodextrin glucanotransferase which comprises culturing a strain belonging to the genus Brevibacterium capable of producing cyclodextrin glucanotransferase, thereby allowing the strain to produce the .gamma.-cyclodextrin glucanotransferase in a culture medium, and subsequently collecting the enzyme, to a process for the production of cyclodextrin which comprises allowing the cyclodextrin glucanotransferase to react with substrate dissolved in a solution, thereby effecting formation of .gamma.-cyclodextrin as a main product, and to a method for increasing .gamma.-cyclodextrin yield without accompanying yield increase of total cyclodextrin, which comprises adding ethyl alcohol to a reaction solution in which .gamma.-cyclodextrin and .beta.-cyclodextrin are formed from starch by the action of .gamma.-cyclodextrin glucanotransferase, thereby effecting repressed formation of .beta.-cyclodextrin and enhanced formation of .gamma.-cyclodextrin. Development of the process of this invention has rendered possible low cost production of .gamma.-cyclodextrin and therefore expands practical use of .gamma.-cyclodextrin to the field of food and the like.
