The purpose of the present invention is to extract oil from the soybean material containing soybean germ as a main component, and to utilize it. The present invention relates to a method for producing a soybean material, comprising crudely crushing selected soybeans into a size of less than &#xbd;, and separating and concentrating a soybean germ fraction by means of sieving, sorting with air, separation based on the grain shape and the like, to the soybean germ fraction produced by said method, to oil prepared from the soybean material containing soybean germ as a main component, to oil containing 0.8% by weight or more of sterols' content, and to foods containing said oil.

A plurality of glass plates 10 are stacked in a block form without forming gaps between adjacent glass plates while the stacked glass plates are separable; the stacked glass plates are cut off in a circular shape or a doughnut-like shape in a block; and then, the processed glass plates are separated. According to this method, tipping which may result when glass plates are processed individually can be prevented whereby processing is easy, and productivity is improved.

A method of preparing .alpha.-L-phenylalanine methyl ester and its hydrochloride, which comprises dissolving .alpha.-L-aspartyl-L-phenylalanine .beta.-methyl ester in a methanol/hydrochloric acid mixture solvent which contains, when hydrochloric acid is expressed in terms of concentrated hydrochloric acid and water, 0 to 20% by volume of methanol, 8 to 55% by volume of concentrated hydrochloric acid and water (balance) in a concentration from 0.01 mol/dl to 0.3 mol/dl; holding the solution at 0.degree. to 60.degree. C. to effect intramolecular ester exchange reaction and crystallize out the formed .alpha.-L-aspartyl-L-phenylalanine methyl ester as its hydrochloride; isolating the hydrochloride; and obtaining, when required, the free ester by neutralization with an alkali, is disclosed.

A method for preparing .alpha.-L-aspartyl-L-phenylalanine methyl ester and its hydrochloride which comprises dissolving .alpha.-L-aspartyl-L-phenylalanine dimethyl ester in a mixture of 0-10% (v/v) methanol, 8-55% (v/v) of concentrated hydrochloric acid, and water (remainder) to a concentration of 0.01 mol/dl to 0.30 mol/dl; holding the resulting solution at one or more temperatures between 0.degree. and 60.degree. C. for a time sufficient for crystals of .alpha.-L-aspartyl-L-phenylalanine methyl ester hydrochloride to precipitate out, and isolating the crystals. The hydrochloride may then be treated with alkali to yield .alpha.-L-aspartyl-L-phenylalanine methyl ester.
