พีพี of the การประดิษฐ์นี้ has
heat resistance at a temperature range above the melting
point of the fat in the พีพี without
contacting water to the surface of the chocolate-like
product after cooling and solidifying or without heating or 20 baking the พีพี after contacting water.
When water activity of the food or food material for
contacting with the พีพี is less than 0.4,
พีพี of the การประดิษฐ์นี้ has heat
resistance at a temperature range above the melting point of the fat in the พีพี by contacting
water to the surface of the พีพี after cooling and solidifying without heating or baking the
พีพี. The reason why the chocolate-
containing food product of the การประดิษฐ์นี้ shows
5 excellent heat resistance is unknown. In the case of
combination with food or food material having 0.4 to 0.95
of water activity, it is assumed that powdered dairy
product and sugar in the พีพี absorb
water by water migration from the food or the food material
10 to the contacted พีพี, and thereby glassy
structures are formed. As a result, it is assumed that the
พีพี has heat resistance even in the
range of temperature where the fat in the chocolate-like
product is molten, 35 to 90°C. In the case of combination
15 with food or food material having less than 0.4 of water
activity, water migration from the food or the food
material is insufficient and it is assumed that powdered
dairy product and sugar in the chocolate absorb water
contacted to the surface of the พีพี, and
20 thereby glassy structures are formed. As a result, it is
assumed that the พีพี has heat resistance
even in the range of temperature where the fat in the
พีพี is molten, 35 to 90°C.
25 Examples of the food or the food material having 0.4
to 0.95 of water activity include dry fruit such as grape and papaya, dried confectionery having 7 to 21 wt% of
moisture such as rice cracker, round bolo, caramel,
marshmallow and jelly beans, semi-moist confectionery
5 having 14 to 440 of moisture such as marron glace, cupcake,
Baumkuchen, pound cake, butter cake, sponge cake and waffle,
dessert confectionery having 65 to 75 wt% of moisture such
as pudding and as jelly, and baked product having 20 to 45
wt% of moisture such as donut, pie, Danish, snack bread,
10 hot dog bun and bread roll. Examples of the food or the
food material having less than 0.4 of water activity
include confectionery having less than 70 of moisture such
as cookie, biscuit, wafers, cracker, potato chip, rice
cracker, okaki (waxy rice cracker), arare (bits of waxy
15 rice cake), okoshi (puffed rice bar).

A viscosity of the chocolate-like product dough of the
การประดิษฐ์นี้ depends on the application of the dough
after preparation, but ทททคือ 2, 000 to 20,000 cP, where
20 the value of the viscosity is obtained by completely
melting the fat in the dough and controlling the
temperature at 45°C and then measuring the viscosity. When
the viscosity of the dough is more than 20,000 cP, it is
not preferable because molding (pouring into the mold) step
25 and coating step of the chocolate-like product become
28
difficult. When the use of the พีพี is a coating for baking confectionery or bread, the viscosity of
the chocolate dough is ทททคือ 2, 000 to 10,000 cP, more
ทททคือ 3,000 to 8,000 cP, where the value of viscosity
5 is obtained by completely melting the fat in the dough and
controlling the temperature at 45°C and then measuring the viscosity. When the viscosity of the dough is less than
2, 000 cP, it is not preferable because the thickness of the coating chocolate is so thin that the base may be seen
10 through the coating, and the taste of chocolate becomes
thinner. When the viscosity of the dough is more than
10,000 cP, it is not preferable because the thickness of
the coating is too thick and the viscosity of the dough
before the coating and during storage may further increase.

The พีพี or the chocolate-containing
food product of the การประดิษฐ์นี้ has heat resistance
in the range of temperature over the melting point of the
fat in the พีพี. However, the surface of
20 the พีพี may be changed to white due to
bloom when the product temperature is reduced to 30°C after
distribution or storage at 40 to 90°C. In this case, it is
preferable to add any of non-tempering hard butter such as
trans acid type hard butter in which main constituent fatty
25 acid is elaidic acid, low trans acid and non-lauric acid
29
type hard butter, and lauric acid type hard butter among the above-described hard butters.
[0036]
Other raw materials which may be included in the
5 พีพี of the การประดิษฐ์นี้ include,
cacao mass, cocoa powder, soy flour, soy milk powder,
concentrated soy protein, isolated soy protein, soy whey,
coffee, vanilla, caramel, fruit, nuts, and fruit powder and
dry fruit, flavoring agent such as nuts, vanilla, herb (e.g. 10 mint), flavor such as vanilla flavor, herb flavor, and
caramel flavor, cereal, puffed food, fruit, cream and
ของผสม ของมัน, and other food ingredients. Color,
flavoring agent and flavor are not limited to the above-
described ingredient, but any ingredients which are known 15 by a skilled person in the art are used.
[0037]
Emulsifiers other than lecithin and PGPR may be
suitably used within the range that both heat resistance and the dough viscosity of พีพี are
20 satisfied. For example, sucrose fatty acid ester, sorbitan
fatty acid ester, polyglycerol fatty acid ester,
fractionated lecithin, and ammonium phosphate may be used.
The utilization purpose ของมัน is, for example,
suppression of bloom and prevention of generation of
25 graining, for addressing a case that the chocolate-like
30
product is exposed to a temperature higher than the melting point of the fat during transport or storage.
[0038]
The chocolate-like product dough of the present
5 การประดิษฐ์ can be prepared by, for example, the
manufacturing method for a usual manner as described below. A dough in paste form is prepared by adding cacao mass and fat which are molten by heating and emulsifier such as
lecithin and PGPR into solid powder material such as cocoa
10 powder, sugar, and powdered milk, then mixing the ของผสม
with a Hobert mixer to prepare the dough having 20 to 30
wt% of fat content. The obtained dough is refined with a
refiner such as roll to make fine particles having 15 to 30
pm of average particle diameter. Then, the obtained dough
15 is subjected to conching (agitating and mixing) to make
smooth paste form while the temperature is kept at 40 to
70°C. Then, fat, emulsifier, and flavor are added and
mixed into the paste to obtain a desired chocolate-like
product dough. When the temperature of conching is more
20 than 80°C, the viscosity of the พีพี
dough increases significantly. Therefore, conching at 40
to 70°C is preferable for the โดห์ พีพี
of the การประดิษฐ์นี้.
[0039]
25 In the preparation of the above พีพี
31
dough, average particle diameter after the refining is
ทททคือ 15 to 30 pm, more ทททคือ 18 to 25 urn, most
ทททคือ 18 to 22 pm. More than 30 pm is not preferable
because the texture becomes slightly rough. In addition,
5 when viscosity of the dough increases in the conching step,
it causes some problems that interfere to the following
molding step, for example, lumps are generated, the dough
tends to adhere to the wall surface of the mixer, long time
is required for obtaining smooth paste, and the viscosity 10 of the resulting โดห์ พีพี is too high.
Therefore, it is important to determine the formulation of
the โดห์ พีพี so that the viscosity
increase of the dough is within an acceptable range. The
formulation of dough of the พีพี of the 15 การประดิษฐ์นี้ conforms to such a determination of the
formulation.
[0040]
Water content of the โดห์ พีพี of the การประดิษฐ์นี้ is ทททคือ 2 wt% or less, more
20 ทททคือ 1 wto or less. When the water content is more
than the upper limit, it is not preferable because the
above-described problems such as viscosity increase and
generation of lumps tend to occur during the preparation of
the dough. In addition, fat content of the chocolate-like
25 product dough of the การประดิษฐ์นี้ is ทททคือ 25 to
32
45 wt%, more ทททคือ 30 to 40 wt%, most ทททคือ 32 to
38 wt%. When the fat content is less than 25 wt%, it is
not preferable because the smooth texture of chocolate is impaired and the texture tends to be rough, and the
5 physical property tends to be sticky due to water
absorption of sugar depending on the storage condition.
When the fat content is more than 45 wt%, it is not
preferable because oil separation (oil-off) to the surface
of the
