Despite the presence of an insoluble solid material
(i.e., a พีพี), the beverage
produced by the above-described method shows improved dispersion
stability, and significantly suppressed sedimentation phenomena, 35 which occur over time, as compared to a beverage produced without
conducting the step of dispersing the พีพี per se in fat and oil (เครื่องดื่มชุดควบคุม).
[0044]
The evaluation of the "ความเสถียรการกระจายตัว" can be
conducted as follows: both of a beverage produced by the above-
described method of the การประดิษฐ์นี้ (present beverage) and a เครื่องดื่มชุดควบคุม are allowed to stand at temperatures from cool to room temperature after being optionally sterilized, and the
sediments of insoluble solid materials (generation of sediment)
generated when the beverages are allowed to stand are observed
over time. Specifically, the ความเสถียรการกระจายตัว of the present
beverage is considered to have been improved when the amount of
the generated sediment is less than that of the เครื่องดื่มชุดควบคุม, or the generation rate of sediment is slower than that of the
เครื่องดื่มชุดควบคุม.
[0045]
Further, even though an insoluble solid material such
as a พีพี settles out and
accumulates on the bottom of the container, the beverage produced 20 by the above-described method shows significantly improved
รีรี so that the initial dispersion state of the
พีพี is easily recovered by
light shaking, as compared to the control beverage.
[0046]
25 The evaluation of the "รีรี" can be
conducted as follows: both of a beverage produced by the above-
described method of the การประดิษฐ์นี้ (present beverage) and a control beverage are allowed to stand at temperatures ranging
from cool to room temperature after being optionally sterilized, 30 and the beverages are compared in terms of ease of dispersion of
the sediment of the insoluble solid material generated when the
beverages are allowed to stand. For example, the รีรี
of the present beverage is considered to have been improved when
the insoluble solid material settled on the bottom of a container 35 can be better redispersed throughout the present beverage than in
18
the เครื่องดื่มชุดควบคุม, or the rate of รีรี is faster than in the เครื่องดื่มชุดควบคุม, after both of the beverages are shaken under the same conditions.
[0047]
5 (II) Beverage Containing พีพี
The beverage according to the การประดิษฐ์นี้
contains at least a พีพี, fat
and oil, and water, wherein (i) the ความเสถียรการกระจายตัว of the
พีพี is improved; or (ii) the 10 รีรี of the พีพี is
improved, as compared to a beverage prepared without conducting
the step of mixing a พีพี with
fat and oil to form สารกระจายตัว (control beverage).
[0048]
15 The beverage of the การประดิษฐ์นี้ having the above-
described features can be produced by the production method
described in section (I) , more specifically the production method
comprising at least steps (a) and (b) The method may further
comprise a homogenization step between step (a) and step (b) The
20 types of beverage components of the การประดิษฐ์นี้ (i.e., the
พีพี and fat and oil), the
amounts of the beverage components, steps (a) and (b) , and the
homogenization step between steps (a) and (b) are as described in
section (I) , and all of which are also applied herein.
25 [0049]
As described above, it is sufficient as long as the
beverage of the การประดิษฐ์นี้ contains at least a powdery
edible processed plant product, fat and oil, and water, and has
the above-described technical features (i) and (ii) As long as
30 the beverage meets these requirements, the production method is
not limited to the above-described production method. [0050]
ทททคือ, while the beverage according to the present
invention contains at least a พีพี, fat and oil, and water, and has the above-described
19
technical features (i) and (ii) , the beverage also has the
feature (iii) that the color fading or color change of the
พีพี in the beverage is suppressed, as compared to the เครื่องดื่มชุดควบคุม.
5 [0051]
The evaluation of the suppression of the color fading
or color change can be conducted as follows: both of a beverage
produced by the above-described method of the การประดิษฐ์นี้
(present beverage) and a เครื่องดื่มชุดควบคุม are sterilized and/or 10 allowed to stand at temperatures ranging from cool to warm
temperature, and the thus-occurring color change of these
beverages is observed over time with reference to the color hue
of the beverages observed immediately after the preparation. For
example, the color fading or color change of the present beverage 15 is considered to have been suppressed when the color hue change
is less than that of the control beverage.
[0052]
(III) Method for Improving ความเสถียรการกระจายตัว or
รีรี of พีพี in
20 Beverage
The การประดิษฐ์นี้ also relates to a method for
improving the ความเสถียรการกระจายตัว or รีรี of a พีพี in a beverage.
[0053]
25 The method can be carried out by mixing a prepared
dispersion of a พีพี in fat and oil with water, and homogenizing the ของผสม in the production
process of a พีพี-containing
beverage.
30 [0054]
The types of the พีพี
and fat and oil used in the method, and the amounts thereof are
as described in section (I), and all of which are also applied
herein.
35 [0055]
The method of the การประดิษฐ์นี้ can be carried out
using a prepared dispersion of a พีพี in fat and oil as a starting material, mixing it with water, and homogenizing the ของผสม in the production of a พีพี-containing beverage; or
the method can be carried out by conducting a step of dispersing
a พีพี in fat and oil (step
(a) ) , and a step of mixing the dispersion with water and
homogenizing the ของผสม (step (b)) These steps employed in the
10 method (a step of dispersing a พีพี in fat and oil (step (a) ) , and a step of mixing the
dispersion with water and homogenizing the ของผสม (step (b) ) )
are also as described in section (I) above, and all of which are also applied herein.
15 [0056]
The above-described method can improve the dispersion
stability or รีรี of a พีพี in a beverage. More specifically, the method according to
the การประดิษฐ์นี้ can improve (i) the ความเสถียรการกระจายตัว of 20 a พีพี, or (ii) the
รีรี of a พีพี in a
beverage containing at least the พีพี, fat and oil, and water, as compared to a beverage
prepared without conducting the step of mixing a พีพี with fat and oil to form สารกระจายตัว
(เครื่องดื่มชุดควบคุม).
[0057]
Furthermore, while the method according to the present
invention has the above-described technical feature (i) or (ii) , the method also has the technical feature (iii) that the color
fading or color change of a powdery edible processed plant
product contained in a beverage is suppressed, as compared to a เครื่องดื่มชุดควบคุม.
[0058]
35 Herein, the meaning and evaluation of the "dispersion stability," "รีรี," and "suppression of the color fading or color change" are as described in section (II) above, and all of which are also applied herein.
