The following Experimental Examples and Examples
describe the การประดิษฐ์นี้. อย่างไรก็ตาม, the การประดิษฐ์นี้ is
not limited to these Examples.

Experimental Example 1
(I) Preparation of Milk-Containing Beverage
(1) The components listed in Table 1 were mixed in the indicated amounts in accordance with the following procedure to prepare fat
15 and oil dispersions 1-1 to 1-3. As a green tea powder (dry
product), Tsujiri Matcha (Tsujiriichihonten Inc., count median
diameter: 24.69 pm) was used.
[0061]
Table 1
Components Amounts (Compositional Ratio)
(a) Skim Milk Powder 10.4 g (2.6%)
(b) Refined Coconut Oil 4.2 g (1.05%)
(c) Green Tea Powder 3.0 g (0.75%)
(d) Ion-Exchanged Water 382.4 g (95.6%)
Total 400.0 g (100.0%)
20 [0062]
Fat and Oil Dispersion 1-1: (a) Skim milk powder, (b) refined
coconut oil, and (d) ion-exchanged water were mixed, and (c)
green tea powder was added thereto. The green tea powder was well
dispersed using a medicine spoon, thereby preparing fat and oil
25 dispersion 1-1 (preparation carried out at 25°C).
Fat and Oil Dispersion 1-2: (c) Green tea powder was mixed with
and dispersed in (b) refined coconut oil, and then the dispersion was mixed with (a) skim milk powder and (d) ion-exchanged water, thereby preparing fat and oil dispersion 1-2.
30 Fat and Oil Dispersion 1-3: (c) Green tea powder was mixed with
and dispersed in (b) refined coconut oil, and then the dispersion
22
was further homogenized at 50°C at 35 MPa using a homogenizer
(Niro Soavi). Subsequently, the homogenized dispersion was mixed
with (a) skim milk powder and (d) ion-exchanged water, thereby
preparing fat and oil dispersion 1-3.
5 [0063]
(2) The obtained fat and oil dispersions 1-1 to 1-3 were
individually heated to 60°C, and homogenized at 60°C at 7,000 rpm
for 60 seconds using a homomixer (Primix Corporation).
Subsequently, the fat and oil dispersions 1-1 to 1-3 were
10 homogenized at 50°C at 35 MPa using a homogenizer (Niro Soavi).
[0064]
(3) The homogenized products 1-1 to 1-3 obtained above were
packed in respective heat-resistant bottles (80 ml) and sealed,
followed by heat sterilization at 110°C for 5 minutes, thereby
15 preparing powdered green tea-containing milk beverages 1-1 to 1-3
[0065]
(II) Evaluation of ความเสถียรการกระจายตัว (Suppression of
Sedimentation) and รีรี, and Evaluation of Color Fading
20 ชาเขียวผง-containing milk beverages 1-1 to 1-3
prepared above were evaluated for color hue, and allowed to stand at room temperature for 3 days. Subsequently, visual observation was performed to evaluate the color hue of each beverage and the
presence or absence of sediment settled on the bottom of each
25 beverage bottle. Thereafter, the heat-resistant bottles
containing the ชาเขียวผง-containing milk beverages were inverted once (after being inverted once, the bottles were
returned to their original position), and evaluated for
รีรี of the sediment. These evaluations were
30 conducted in accordance with the following criteria (the same
applies to Experimental Examples 2 to 4)
[0066]
Criteria
*1: Presence or Absence of Sediment
35 "-": none, "+": present in a small amount, "+": present, "++":
23
present in a significant amount
*2: Color Hue
"@": no change to brown color, "0"; turned slightly brownish, 5 "A": turned brownish, "x": turned significantly brownish
*3: รีรี
"A": Excellent (the initial dispersion state is almost fully
recovered, "B": slightly poor (sediment remains on the bottom of 10 a bottle), "C": poor (almost no dispersion occurs)
[0067]

As shown in Table 2, ชาเขียวผง-containing milk
beverages 1-2 and 1-3 prepared using a prepared fat and oil
dispersion obtained by mixing ชาเขียวผง with fat and oil
(refined coconut oil) to form สารกระจายตัว in the production of 20 the ชาเขียวผง-containing milk beverages showed improved
ความเสถียรการกระจายตัว of the ชาเขียวผง and significantly
suppressed sedimentation of the green tea powder, which occurs in
storage after heat sterilization, as compared to powdered green
tea-containing milk beverage 1-1 produced without preparing the
25 fat and oil dispersion. The results also confirmed that powdered
green tea-containing milk beverages 1-2 and 1-3 showed
significantly suppressed degradation of color hue (color fading)
24
of the green tea powder, which is caused by heat sterilization, as compared to ชาเขียวผง-containing milk beverage 1-1. [0070]
A comparison between the cases where the fat and oil
5 dispersion was homogenized (ชาเขียวผง-containing milk
beverage 1-3) and not homogenized (ชาเขียวผง-containing
milk beverage 1-2) revealed no significant difference in
ความเสถียรการกระจายตัว (presence or absence of sediment),
degradation of color hue (color fading), and รีรี.
10 [0071]
Experimental Example 2
The same procedures for preparing ชาเขียวผง-
containing milk beverages 1-1 and 1-2 in Experimental Example 1
were repeated using "linen no Shiro" (Aiya Co., Ltd., count
15 median diameter: 12.23 pm) in place of the Tsujiri Matcha
(Tsujiriichihonten Inc.) as a green tea powder, thereby preparing
ชาเขียวผง-containing milk beverages 2-1 and 2-2.
ชาเขียวผง-containing milk beverages 2-1 and 2-2 were
evaluated for ความเสถียรการกระจายตัว (presence or absence of
20 sediment), degradation of color hue (color fading), and
รีรี in accordance with the method and criteria
described in section (II) of Experimental Example 1.

As shown in Table 3, ชาเขียวผง-containing milk
beverage 2-2 prepared using a prepared fat and oil dispersion obtained by mixing green tea powder with fat and oil (refined coconut oil) to form สารกระจายตัว in the production of the
5 ชาเขียวผง-containing milk beverage showed improved
ความเสถียรการกระจายตัว of the ชาเขียวผง and significantly suppressed sedimentation of the ชาเขียวผง, which occurs in storage after heat sterilization, as compared to powdered
green tea-containing milk beverage 2-1 produced without preparing 10 the fat and oil dispersion. The results also confirmed that
powdered green tea-containing milk beverage 2-2 showed
significantly suppressed degradation of color hue (color fading) of the green tea powder, which is caused by heat sterilization, as compared to ชาเขียวผง-containing milk beverage 2-1.

1670 (Mitsubishi-Kagaku Foods Corporation; sugar ester),
สารก่ออิมัลชัน 681SPV (Taiyo Kagaku Co., Ltd.), and ion-exchanged

30 green tea powder was well dispersed using a medicine spoon,
26
thereby preparing fat and oil dispersion 3-1.
Fat and Oil Dispersion 3-2: Green tea powder was mixed with and dispersed in refined coconut oil using a medicine spoon.
Subsequently, the dispersion was mixed with สารก่ออิมัลชันs P-1670
5 and 681SPV and ion-exchanged water, thereby preparing fat and oil
dispersion 3-2.
[0078]
(2) The obtained fat and oil dispersions 3-1 and 3-2 were
individually heated to 60°C, and homogenized at 60°C at 7,000 rpm
10 for 60 seconds using a homomixer (Primix Corporation).
[0079]
(3) The homogenized products 3-1 and 3-2 were packed in
respective heat-resistant bottles (80 ml) and sealed, followed by
heat sterilization at 110°C for 5 minutes, thereby preparing
