DESCRIPTION
Title of Invention: METHOD FOR MANUFACTURING BEVERAGE CONTAINING PROCESSED EDIBLE-PLANT POWDER HAVING IMPROVED DISPERSION
STABILITY OR REDISPERSABILITY
5
Technical Field [0001]
The การประดิษฐ์นี้ relates to a beverage containing
a powdery, edible, processed plant product, wherein the dispersion stability of an insoluble solid material (powdery,
edible, processed plant product) is improved so that the
sedimentation of the material is suppressed, and the
redispersibility is improved so that the initial dispersion state can easily be recovered by lightly shaking the beverage when sedimentation has occurred. The การประดิษฐ์นี้ also relates to
a method for producing the beverage.
[0002]
The การประดิษฐ์นี้ further relates to a method for
improving the dispersion stability of an insoluble solid material 20 (powdery edible processed plant product) in a beverage, and also
relates to a method for improving the redispersibility so that
the initial dispersion state is easily recovered by lightly
shaking the beverage when sedimentation has occurred.
Background Art
[0003]
Because of its deep, natural flavor, matcha (powdered
green tea) has been consumed as a beverage and used as a
component for beverages, as well as used as an additive to a variety of foods and drinks. With today's growing health
consciousness, dry powders of green-and-yellow vegetables, such as kale and barley (young grass), have also been consumed as a beverage, and used as a component for beverages and an additive to a variety of foods and drinks.
However, these dry powders, which are water-insoluble
solid materials (insoluble solid materials), are disadvantageous
in that when they are contained in beverages, especially when
such beverages are packed into containers and distributed to the 5 market as packaged beverages, the powders settle out
(sedimentation), or coagulate and solidify on the bottom of the containers during distribution or storage. Further, the
sterilization treatment conducted in the production process of such packaged beverages causes the dry powders of green-and-
yellow vegetables to undergo fading or change of their bright
color. This problem, as well as the sedimentation problem, causes
spoilage of the appearance and flavor (texture) of the beverages. [0005]
Typically used methods to solve these problems are those for suppressing the sedimentation of an insoluble solid
material using a stabilizer such as cellulose and polysaccharide thickeners. Other proposed methods include a method for improving the retention of green color of powdered green tea or the
dispersibility and solubility of powdered green tea in an aqueous medium by mixing the powdered green tea with maltose and a
calcium preparation derived from, for example, oyster shells, and
adding the mixture to foods and drinks (Patent Document 1) ; and a
method for stabilizing the dispersion of an insoluble solid
material, such as powdered green tea, by adding a stabilizer and hot or non-hot water to the insoluble solid material,
homogenizing the mixture at a pressure of 100 to 250 kg/cm2 to
colloidally disperse the stabilizer in the mixture, and allowing
the insoluble solid material to be held in the colloid (Patent
Document 2) However, the use of a stabilizer or the like may cause unnatural texture and flavor in a beverage. The use of a
stabilizer also increases the cost of the beverage. [0006]
As a method not using a stabilizer, there has been
proposed a method for suppressing the sedimentation and coagulation of an insoluble solid material in a beverage by
dispersing a green tea powder having a mean particle diameter of
7 to 20 pm in water, and homogenizing the mixture at 20 to 90°C
at a pressure of 5 MPa or more (Patent Document 3) However, this
method can only be applied to a green tea powder having a mean particle diameter ranging from 7 to 20 pm, and thus preadjustment
of the mean particle diameter of the powder is required; hence, the method is cumbersome and impractical.
