DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a method for producing a yeast extract; and more specifically, the present invention relates to a method for producing a yeast extract, comprising integrated processes to actively remove yellow or brown color specific to yeast extract and further optionally remove a characteristic odor of yeast extract, and the present invention additionally relates to a cosmetic product with the yeast extract blended therein.
TECHNICAL BACKGROUND
Yeast extract has been used widely as a seasoning comprising natural materials, and yeast extract has characteristics such that it highly safe and has complex taste such as unique flavor and body which artificial seasonings is absent. In recent years, furthermore, yeast extract has been drawing attention as materials for cosmetics and healthy food, wherein useful amino acids and nucleic acids contained in yeast extract are effectively utilized.
However, yeast extract has unique yellow or brown color and characteristic odor, and these work as factors severely limiting the applicable range of yeast extract or the amount thereof to be used.
For the purpose of removing such color or odor, therefore, various proposals have been made conventionally. For example, the proposals are made about deodorizing by means of hydrophobic resins (Japanese Patent Application No. 131064/1992 etc.), deodorizing by means of enzyme treatment, chemical treatment methods by acids or alkalis (Japanese Patent Laid-open No. 11188/1976 etc.), or yeast selection for producing yeast extract (Japanese Patent Laid-open No. 66861/1974). Although the processes of these methods are very laborious, however, the resulting advantages are poor disadvantageously, so the methods are not so frequently carried out currently.
The reason of the coloring of yeast extract lies in that at the process of producing yeast extract, saccharides (carbohydrates) and amino acids cause aminocarbonyl reaction through the heating process, with the resultant production of a substance colored dark brown. Heating treatment is carried out in the course of producing seasonings and cosmetics from a raw material yeast extract, so those nearly colorless at the stage of raw materials might potentially be colored at the intermediate stage of the production methods.
DISCLOSURE OF THE INVENTION
In accordance with the present invention, therefore, it has been found that the color specific to yeast extract can prominently be reduced by subjecting a yeast extract solution obtained in a conventional manner, to heating treatment to preliminarily generate colored substances in the yeast extract and thereafter separating and removing the colored substances, and thus, the present invention has been achieved.
It is an object of the present invention to provide a method for producing a yeast extract with the improvement in color and odor which are specific to the yeast extract but with useful substances such as amino acid retained therein, and to further actively apply the yeast extract to fields where yeast extract has conventionally been applied with much difficulty.
In a first aspect of the present invention, it is provided a method for producing a yeast extract, comprising a heating process of a yeast extract solution obtained in a conventional manner and an adsorption process of putting the resulting extracts solution colored at said heating process in contact to an ion exchange resin so as to remove the colored substances in the yeast extract solution.
In a second aspect of the present invention, it is provided a method for producing a yeast extract, comprising a heating process of a yeast extract solution obtained in a conventional manner, a filtration process of removing the solids as produced at the heating process and polymeric components in the extract solution and an adsorption process of putting the yeast extract solution in contact to an ion exchange resin so as to remove the colored substances in the extract solution after the filtration process.
In a third aspect of the present invention, i
