    摘要: Provided is a method of producing a banana-derived composition by which a composition exhibiting excellent biological activity is obtained from a flesh part of a banana. The method includes the steps of (1) mincing a flesh part of a banana to obtain flesh fractions; (2) adding a proteolytic enzyme to the flesh fractions and decomposing proteins contained in the flesh fractions through an enzyme reaction, to obtain an enzymatic reactant; and (3) deactivating the proteolytic enzyme contained in the enzymatic reactant to obtain a composition A.

    摘要: Optically active tryptophan of high purity can be obtained in high yields from a tryptophan fermentation broth, using crystallization of optically active tryptophan hydrochloride in combination with concurrent neutralization crystallization. According to the present invention, optically active tryptophan from a tryptophan containing fermentation broth, is carried out by (a) removing cells from the fermentation broth, adding hydrochloric acid, or a mixture of hydrochloric acid and an inorganic salt which contains chloride ions, to the cell-free broth to effect crystallization, (b) separating optically active tryptophan hydrochloride, (c) dissolving the optically active tryptophan hydrochloride, and (d) subjecting the resulting solution and an alkali solution to concurrent neutralization crystallization, maintaining a pH of the crystallization solution in the range of from 3 to 8.
