30 [0009]
Further, an object of the การประดิษฐ์นี้ is to
provide a method for improving, preferably by not using a

Solution to Problem
5 [0010]
The present inventors conducted extensive research to
solve the above-described problems, and found that in the
production of a beverage containing a พีพี, when สารกระจายตัว prepared by mixing a พีพี with fat and oil, rather than a
พีพี per se, is added to water
for beverage preparation, the resulting beverage shows
significantly improved ความเสถียรการกระจายตัว of the พีพี so that the sedimentation that occurs
15 over time is suppressed, and also shows significantly improved
รีรี of the generated sediment so that the initial
dispersion state is easily recovered by light shaking, as
compared to beverages prepared by adding a พีพี per se to water for beverage preparation 20 (hereinafter, the latter beverages are referred to as "control
beverage").

The การประดิษฐ์นี้ was completed based on these
findings, and includes the following embodiments.

[0013]
(II) Beverage Containing พีพี
(II-1) A beverage, which is obtained by the method according to
any one of items (I-1) to (I-6) , the beverage containing at least
a พีพี, fat and oil, and water, the beverage showing at least improved ความเสถียรการกระจายตัว of
the พีพี, or improved
รีรี of the พีพี, as compared to a beverage prepared without conducting step (a) of
mixing a พีพี with fat and oil to form สารกระจายตัว.
(II-2) The beverage according to item (II-1) , which shows
suppressed color fading or color change of the พีพี.
[0014]
(III) Method for Improving ความเสถียรการกระจายตัว or

35 (III-1) A method for improving ความเสถียรการกระจายตัว or
6
รีรี of a พีพี in a beverage, the method comprising, in production of the beverage
containing the พีพี,
the step of mixing a prepared dispersion of the powdery
5 edible processed plant product in fat and oil with water, and
homogenizing the mixture.
(III-2) A method for improving ความเสถียรการกระจายตัว or
รีรี of a พีพี in a
beverage, the method comprising, in production of the beverage
10 containing the พีพี, the steps
of (a) dispersing the พีพี in
fat and oil; and (b) mixing the dispersion of the powdery edible
processed plant product in the fat and oil with water and
homogenizing the mixture.
15 (III-3) The method according to item (III-2) , further comprising
a homogenization step between step (a) and step (b)
(III-4) The method according to any one of items (III-1) to (III-

Advantageous Effects of Invention [0015]
5 The production method and the method for improving the
ความเสถียรการกระจายตัว or รีรี according to the present
invention can improve, preferably without using a สารเพิ่มความเสถียร or
an emulsifier, the ความเสถียรการกระจายตัว of an insoluble solid
material (พีพี) in a beverage
10 containing the พีพี such as
powdered green tea, and the รีรี so that the initial
dispersion state is easily recovered by light shaking when
sedimentation has occurred, as compared to a beverage prepared
without conducting a step of mixing a พีพี with fat and oil to form สารกระจายตัว. Moreover, in
the use of a green-and-yellow vegetable, particularly a vegetable
containing a green piyment (i.e., chlorophyll) as an edible
processed plant product, the production method according to the
การประดิษฐ์นี้ can suppress the color fading or color change 20 of the พีพี in a beverage,
which is caused by heat sterilization or storage, as compared to
a beverage prepared without conducting the step of mixing a
พีพี with fat and oil to form a
dispersion.
