Abstract:
The present invention relates to novel Aspergillus oryzae CJ 1354, isolated and identified from Korean traditional meju, exhibiting high enzymatic activities in rice as a substrate, a method for preparing a rice hot pepper paste having an improved flavor using the same, and a rice hot pepper paste prepared by the method. Specifically, the method comprises a process in which rice milled to have a certain whiteness is treated with high-pressure steam having a pressure of 2.0-4.0 kgf/cm2 in a steaming step to control the viscosity and water content of the steamed rice to thereby prevent agglomeration from occurring during transfer of the steamed rice. Also, in the method, novel Aspergillus oryzae CJ 1354 is used in a step of making rice koji.
Abstract:
An enzyme, which has a molecular weight of about 57,000-120,000 daltons on SDS-PAGE and a pI of about 3.8-5.1 on isoelectrophoresis using ampholyte, converts maltose into trehalose and vice versa. The enzyme was isolated from microorganisms of the genera Pimelobacter, Pseudomonas and Thermus. By using the enzyme, trehalose is readily formed from a commercially available maltose in an industrial scale and a relatively-low cost. Trehalose and saccharide compositions containing the same, which are preparable with the enzyme, are suitably used in food products, cosmetic compositions and pharmaceutical compositions.
Abstract:
This invention provides a method for rapidly measuring an premature yeast flocculating factor of malt contained in a brewing material, comprising the following steps of: (1) mixing yeast in the late logarithmic growth phase or thereafter with a water-extracted high molecular fraction prepared from a test material sample in a buffer solution and suspending the mixture in the buffer solution; and (2) irradiating the suspension obtained in the step (1) with visible light, photographing the scattered light with a camera device, image-analyzing the image data thus obtained and determining the degree of whiteness of the suspension to measure the degree of sedimentation of the yeast in the suspension. According to the present invention, the premature yeast flocculating factor of malt contained in the brewing material can be measured in a highly accurate, rapid and simple manner, and, further, even a plurality of analytes can be rapidly measured.
Abstract:
Granulated bean paste or “miso” is made by partially drying uncooked bean paste by vacuum freeze drying, thoroughly mixing and then storing the semi-dried bean paste in an isothermal chamber at a substantially consistent temperature within the range of 15° C. to 20° C. for a few days to homogenize the water content in the semi-dried bean paste, then extruding the semi-dried bean paste into an elongated form, and finally cutting and breaking the bean past material to obtain fine particles of granulated bean paste.
Abstract:
A method for preparing the high protein nutrient from oilseed-based material is provided. The modified oilseed-based material produced by the process can be utilized in a wide variety of applications, including the preparation of fermentation media. The oilseed-based product typically includes at least about 55 wt. % protein (dry basis), low levels of soluble sugars, such as raffinose, stachyose and saccharose and has a FAN content of at least about 15 mg/g. Fermentation media and aqueous nutrient solutions derived from the modified oilseed material are also provided.
Abstract:
Vegetable sources of cancer chemoprotective agents have been identified which are extraordinarily rich in glucosinolates, metabolic precursors of isothiocyanates. The vegetable sources are used to provide a dietary source for reducing the level of carcinogens in mammals.
