A similar RP-HPLC method has been developed for the determination of isoflavones in soybean powder. Ground soybean powder (100 g) was extracted four times with 300 ml of hexane, then the defatted powder was extracted with six solvents or solvent mixtures such as acetone, methanol-water (4 1, v/v), methanol-ethyl acetate-acetone (1 1 1, v/v), acetone-0.1 M HC1 (5 1, v/v), methanol-water (4 1, v/v) plus 0.1 M HC1 (5 1, v/v), and methanol-ethyl acetate-acetone (1 1 1, v/v) plus 0.1 M HC1 (5 1, v/v). An aliquot of 0.5 g defatted or non-defatted soybean powder was shaken for 2h or sonificated for lh with 5 ml...

As a second example, a biosensor for urea could be constructed using an ammonia gas-sensing electrode [10] or a biocomposite containing soybean powder, polymer matrix and manganese dioxide as pH-sensing electrode [5]. 

To a medium having a composition of 6.4 % of millet jelly, 0.5 % of glucose, 3.5 % of soybean powder, 0.75 % of corn steep liquor, 0.3 % of sodium chloride, 0.1 % of potassium secondary phosphate, 0.05 % of zinc sulfate, 0.01 % of copper sulfate, 0.2 % of sodium nitrate and 0.01 % of Toho No. 1 (trade name for a surface active agent composed of polyoxyethylene manufactured by Toho Chemical Industry Co. Ltd., Japan) was added 3-amino-propyl-dimethylsulfonium bromide hydrobromate in a proportion of 0.4 mg/ml to adjust the pH of the medium to 6.5.
