Definitions
- the present invention relates to a method for producing a processed soybean beverage. More specifically, the present invention relates to processing techniques that enhance the soy flavor of soy beverages.
- soy beverages has increased significantly due to various reasons such as the recent health boom, dealing with allergy problems, religious reasons, and increased home demand due to the spread of infectious diseases.
- soy milk made only with soybeans and water without bean curd refuse, soybean solids content of 8% by weight or more, soybean solids content of 6% by weight or more, blended with additives such as sugar and rice oil.
- Patent Document 1 a method of obtaining soymilk with reduced soybean odor by reacting soymilk with a plant-derived, animal-derived, or yeast-derived protease
- Patent Document 2 A method of obtaining soymilk with reduced soybean odor by reacting aminopeptidase derived therefrom (Patent Document 2).
- JP-A-2004-16215 Japanese Patent Application Laid-Open No. 2005-105503
- an object of the present invention is to provide a technique for enhancing the soybean flavor of soybean beverages.
- the present inventor found that treating soybean beverages with filamentous fungus-derived protease enhanced the original flavor of soybeans. That is, the present invention provides inventions in the following aspects.
- Section 1 A method for producing a processed soybean beverage, comprising the step of allowing a filamentous fungus-derived protease to act on a soybean beverage.
- Section 2. Item 2. The production method according to Item 1, wherein the soybean beverage is soymilk.
- Item 3. Item 3. The production method according to Item 1 or 2, wherein the filamentous fungus-derived protease is an acid protease.
- Section 4. Item 4. The production method according to any one of Items 1 to 3, wherein the filamentous fungus-derived protease is an Aspergillus-derived protease.
- Item 5. Item 5.
- Item 6 The production method according to any one of Items 1 to 4, wherein the filamentous fungus-derived protease is Aspergillus oryzae-derived protease.
- Item 6 The production method according to any one of Items 1 to 5, wherein the processed soybean beverage has a viscosity of 8 mPa ⁇ s or more.
- Item 7. A soybean flavor enhancer for soybean beverages, comprising a filamentous fungus-derived protease.
- the soybean flavor of the soybean beverage can be enhanced by treating the soybean beverage with a filamentous fungus-derived protease.
- the method for producing a processed soybean beverage of the present invention is characterized by including a step of allowing filamentous fungus-derived protease to act on the soybean beverage.
- the method for producing the processed soybean beverage will be described in detail below.
- the soybean beverage used in the present invention is a beverage using soybeans as a material, and may be a liquid composition containing at least crushed cotyledon portions of soybean seeds dispersed in water.
- the soybean beverage may contain crushed hypocotyls and/or seed coats dispersed in water in addition to crushed cotyledon parts.
- soybean beverages include liquids obtained by crushing and dispersing soybeans in water, liquids obtained by removing bean curd refuse from liquids obtained by crushing and dispersing soybeans in water (i.e., soymilk), and liquids prepared from these liquids. and a liquid obtained by dissolving and/or dispersing the dried powder in water.
- soybean beverages may be used singly or in combination.
- soymilk is preferred.
- the amount of protein in the soybean beverage is not particularly limited, but is, for example, 1 g/100 ml or more, preferably 2 g/100 ml or more, more preferably 3 g/100 ml or more, still more preferably 3.5 g/100 ml or more, still more preferably 4 g/100 ml.
- the above are mentioned.
- the upper limit of the protein amount range in the soybean beverage is not particularly limited, examples thereof include 8 g/100 ml or less, 6 g/100 ml or less, 5 g/100 ml or less, or 4.5 g/100 ml or less.
- the soybean solid content in the soybean beverage is not particularly limited, but is, for example, 2% by weight or more, preferably 4% by weight or more, and more preferably 8% by weight or more.
- the upper limit of the soy solids content range in the soy beverage is not particularly limited, but includes, for example, 16 wt% or less, 14 wt% or less, 12 wt% or less, or 10 wt% or less.
