New (2R,4R) monatin monosodium salt hydrate crystals characterized by having specific characteristic X-ray diffraction peaks provide general-purpose, stable, and safe monatin sodium salt crystals incorporating no organic solvent. These crystal may be prepared by a method that requires no organic solvent in the crystallization, separation, and drying steps. These crystal are useful as sweeteners and for the preparation of orally consumed products, such as foods, beverages, pharmaceutical products, topical pharmaceutical products, and feeds containing general-purpose, stable, and safe monatin sodium salt crystals.

Monatin hydrate crystals

Crystals of (2R,4R)-monatin potassium salt which exhibit an X-ray powder diffraction pattern having characteristic peaks at diffraction angles 2&#x3b8; of 5.5&#xb0;, 7.2&#xb0;, 8.1&#xb0;, 8.9&#xb0;, and 16.3&#xb0;, by powder X-ray diffraction (Cu&#x2014;K&#x3b1; radiation), are superior in sweetness, preservation stability, solubility, and color stability.

Crystal of (2R,4R)-monatin potassium salt and sweetener composition containing same

The present invention provides a novel crystal of alanine alkyl ester sulfonate having low hygroscopicity and low corrosiveness, which can be produced industrially economically. The present invention provides crystals of alanine alkyl ester sulfonates represented by formula (1): wherein Ris a methyl group or an ethyl group, provided that when Ris a methyl group, Ris an ethylphenyl group or a dimethylphenyl group; and when Ris an ethyl group, Ris a methyl group, a phenyl group, a chlorophenyl group, an ethylphenyl group, or a dimethylphenyl group.

Crystal of amino acid ester salt and process for producing the same

N-[N-[3-(2-hydroxy-substituted phenyl)propyl]-L-&#x3b1;-aspartyl]-L-phenylalanine 1-methyl ester derivatives, which are useful as sweeteners, may be conveniently produced by subjecting a 2-hydroxychroman derivative having various substituents on the benzene ring and aspartame to a reductive alkylation reaction. These compounds may be purified by subjecting such a derivative containing one or more impurities to a crystallization step to crystallize the same. Further, there are provided a process for producing dialkoxychroman derivatives useful as intermediates for the production of such aspartame derivatives in the above process, and novel dialkoxychroman derivatives thus produced, which are excellent as the production intermediate.

Herein are disclosed a process for producing xylitol of high purity (one-step desalting process) which comprises the steps of (1) removing the solid matter from a culture froth obtained by culturing a xylitol-producing microorganism in an aqueous culture medium, (2) desalting the resulting solid matter-removed culture broth by removing the ionic substances therefrom by means of a cation-exchange resin and an anion-exchange resin, (3) subjecting the resulting desalted solution to the chromatography using a strongly acidic cation-exchange resin to separate the xylitol from the other sugar alcohol(s) and sugar(s), and (4) obtaining the xylitol by separating it at a high purity from the resulting xylitol solution (fraction), and to a similar process (two-step desalting process) but wherein the desalting carried out twice by adding the ion-exclusion step between Steps (1) and (2) of the above-mentioned process, whereby most of the ionic substances are removed, by which processes highly pure xylitol can be obtained from a xylitol solution in a commercially effective way, in the method for producing xylitol by using a xylitol-producing microorganism.

Process for producing xylitol of high purity

Disclosed herein is a printing method comprising a step of applying a liquid composition containing a cationic substance and an ink containing an anionic substance respectively on a recording medium so that the liquid composition and the ink are in contact with each other on the recording medium, wherein the ink contains a coloring material at a concentration of not higher than 1% and has a pH of 10.5 or higher. The printing method permits the provision of an image having excellent water fastness, image quality and resistance to bleeding on plain paper and can prevent the occurrence of whitish haze at a highlight part.

Printing method, image forming process, ink, ink set, recording unit, image forming apparatus and print

An image forming method to apply an ink to a printing medium includes applying a liquid composition having a polarity different from a polarity of the ink to an image forming region formed by the ink and the vicinity of the image forming region on the printing medium prior to the application of the ink, wherein a surface tension of the liquid composition is higher than that of the ink.

Image forming method, ink-jet recording method and instruments used in such methods

Provided is an ink-jet recording process for forming a color image on a recording medium using a liquid formulation and a color ink in combination, wherein the liquid formulation contains a cationic polymer having a weight-average molecular weight in the range of from 400 to 1,400, and the liquid formulation and the ink are each ejected from a recording head having an ink ejection volume per dot of from 2 to 25 picolitters.
