(I) Method for Producing Beverage Containing พีพี
The การประดิษฐ์นี้ relates to a method for producing
a beverage containing a พีพี,
wherein at least the ความเสถียรการกระจายตัว of the พีพี is improved, or the รีรี of the พีพี is improved.
[0018]
The production method can be carried out by at least
the following steps (a) and (b) :
(a) mixing a พีพี with fat and
oil to form สารกระจายตัว; and
(b) mixing the dispersion of the พีพี in the fat and oil with water, and homogenizing the
ของผสม.
[0019]
The following describes each step.
Step (a) : Dispersion Step
The term "พีพี" as
used in step (a) refers to a water-insoluble edible processed plant product prepared as a powder. Specifically, the พีพี refers to those prepared by
grinding the edible part of plants such as fruits, vegetables
(root vegetables, stem and bulb vegetables, leaf vegetables,
flower vegetables, and fruit vegetables) and tea leaves, and preferably dry powders thereof. The พีพี according to the การประดิษฐ์นี้ may be those
prepared from one type of edible plants, or a ของผสม prepared by 35 combining any two or more types of edible plants. The term
"powdery" in the การประดิษฐ์นี้ refers to not only those having a powdery shape, but those processed in the form of granules or solids (e.g., tablets) from a powder.
[0020]
The vegetables are not particularly limited, and
include any of root vegetables (e.g., carrots, burdock roots, and
radishes), stem and bulb vegetables (e.g., asparaguses, onions,
and purple onions), leaf vegetables (e.g., spinach, kale, barley
(young grass), cabbage, Chinese cabbage, parsley, basil, mugwort, 10 watercress, Angelica keiskei, mulukhiyah, shiso (Perilla
frutescens var. crispa), and egoma (Perilla frutescens var. frutescens))
, flower vegetables (e.g., cauliflower, and broccoli), and fruit
vegetables (e.g., bell peppers, paprika, tomatoes, and pumpkin); 15 and are preferably green-and-yellow vegetables. Among green-and-
yellow vegetables, preferable are green vegetables such as
spinach, kale, barley (young grass), parsley, basil, mugwort,
watercress, Angelica keiskei, komatsuna (Brassica rapa var.
perviridis), broccoli, bell peppers, mulukhiyah, shiso (Perilla
frutescens var. crispa), and egoma (Perilla frutescens var.
frutescens); and more preferable are kale and barley (young
grass), which are typically used in green juice. [0021]
Preferable examples of powdery tea leaves include
matcha (ชาเขียวผง), which is a powder of tencha. Matcha
is typically prepared as follows. Shade-grown tea leaves
(ooishita leaves) are steamed, cooled, and dried without rolling, and the obtained dry leaves are broken into small pieces,
followed by removal of the stems, petioles, and leaf veins. The
resultant product is further dried to prepare tencha, which is
then ground to a powder (fine powder) with a mill.
[0022]
The พีพี of interest
in the การประดิษฐ์นี้ is preferably ชาเขียวผง
(matcha) and a dry powder of a leaf vegetable selected from the
group consisting of kale, barley (young grass), komatsuna
(Brassica rapa var. perviridis), and spinach, more preferably
ชาเขียวผง, kale, and barley (young grass), and further more preferably ชาเขียวผง.
5 [0023]
The particle diameter of the powdery edible processed
plant product (insoluble solid material) used in the present
invention is not particularly limited; for example, the median
diameter (count median diameter) of the dry product is 5 pm or
more, preferably 10 to 150 pm, more preferably 10 to 100 pm,
further more preferably 10 to 80 pm, and still further more
preferably 20 to 50 pm. The count median diameter can be measured in accordance with a laser diffraction scattering technique using a device such as a SALD-2200 (Shimadzu Corporation) laser
diffraction particle diameter distribution analyzer.
[0024]
The "fat and oil" as used in step (a) is not
particularly limited. Examples thereof include fat and oil
typically used in foods. Specifically, the fat and oil is a
vegetable oil (e.g., coconut oil, soybean oil, canola oil,
cottonseed oil, corn oil, sunflower oil, and safflower oil) and
an animal fat and oil (e.g., beef tallow, lard, and milk fat),
and preferably fat and oil having a melting point of room
temperature (15 to 25°C) or less. In other words, fat and oil in
liquid form at room temperature is a preferable example. Such fat
and oil is preferably a vegetable oil, more preferably coconut
oil, soybean oil, canola oil, cottonseed oil, corn oil, sunflower
oil, and safflower oil, and further more preferably coconut oil
(ascending melting point: 25°C) From the standpoint of its
flavor, price, etc., coconut oil (refined) is usually used.
Coconut oil is relatively easy to handle in a manufacturing setting because coconut oil is liquefied by slight heating.
Preferable are oils that are refined such that the smell and color thereof do not affect the final beverage products (e.g.,
refined coconut oil).
[0025]
In step (a) , the amount of the พีพี to be mixed with and dispersed in fat and oil is
selected from the range of 1 to 200 parts by weight, preferably
10 to 150 parts by weight, and more preferably 50 to 100 parts by
weight, per 100 parts of the fat and oil (on a dry weight basis).
[0026]
From the standpoint of the advantageous effects of the
การประดิษฐ์นี้, an actually produced, final beverage product
comprises the พีพี (on a dry
weight basis) in an amount selected from the range of 0.1 to 20
wt%, preferably 0.3 to 10 wt%, and more preferably 0.5 to 5 wt%
based on the amount of the beverage taken as 100 wt%. The final
beverage product comprises the fat and oil in an amount selected
from the range of 0.1 to 50 wt%, preferably 0.5 to 10 wt%, and
more preferably 1 to 5 wt% based on the amount of the beverage taken as 100 wt%. Thus, it is preferable to suitably adjust the above-described amount of the พีพี relative to the amount of fat and oil so that the amounts 20 of the พีพี and fat and oil in
the final beverage product fall within the above-described
numerical ranges.
[0027]
The method for dispersing a พีพี in fat and oil is not particularly limited. For
example, a พีพี, preferably a dry powder of an edible processed plant product, per se, may be added to fat and oil, and mixed with stirring in accordance with a conventional technique.
[0028]
The dispersion step is preferably in the absence of
water other than the water contained in the fat and oil and the
พีพี used as starting materials.
Specifically, it is preferable that water is not additionally
35 added (external addition) in the dispersion step. In this manner,
12
an edible plant-derived component, such as a greenish yellow natural pigment, can be efficiently eluted, dissolved, and dispersed in the fat and oil.
[0029]
5 This dispersion step is basically a step of dispersing
only a พีพี in fat and oil per se, and it is not particularly necessary to add an additive such as a สารเพิ่มความเสถียร and an สารก่ออิมัลชัน in this step. Specifically, it
is preferable not to use an additive such as a สารเพิ่มความเสถียร and an สารก่ออิมัลชัน in the dispersion step.
