BACKGROUND OF THE INVENTION
The present invention relates to a crusty or specialty type bread
product and the method of manufacturing the same. A crusty or specialty bread
product is exemplified by the traditional French bread, i.e., a bread being rather
doughy on the inside, yet light, and having a harder crust on the outside. It is
a principal thrust of the invention disclosed herein to provide a specialty or
crusty bread to the end user which can be at least in part baked on the end user's
premises. This provides the end user with a delicious product which he feels was
"baked on the premises" and, in addition, it provides a sense of the freshly baked
aroma of bread. It is a significant advance over merely reheated breads which
have already been fully baked and then frozen.
Neighborhood bakeries, supermarket in-store bakeries, and specialty
and gourmet shops are seeking to appeal to end users with a fresh baked line of
authentic French and other hard crusted breads. The method disclosed herein only
requires about 10 to 15 minutes to "finish off" the bread by baking the already
partially-baked dough in any type of oven, whether it is a domestic oven, a convection
oven, a semi-industrial oven, etc., but not, however, a microwave oven.
Independent of whether the product is placed into the finishing oven
in a fully frozen state, a thawed and then refrigerated state or a thawed and stored
at room temperature state, upon finish baking, the result is a spectacular, fresh-baked
product that retains its freshness for up to about 24 hours. Unlike products advertised
as "brown and serve," the bread product produced hereby has been fully proofed,
cut, steamed and partially-baked in ovens where the humidity has been precisely
controlled.
DESCRIPTION OF THE PRIOR ART
There exists, of course, in the prior art, fully baked and then frozen
breads which are sold in the frozen state to the end user or consumer. When the
end user desires to serve this product, he or she removes the same from the freezer
and merely reheats it. This, however, does not provide the end user with a sense
of "freshly baking it on the premises" nor does it really provide the aroma of
a freshly baked bread product and, further, it does not form a crust that will
stay on the loaf. Furthermore, this type of product does not have the freshness
of truly fresh baked bread products.
The invention disclosed herein in intended to provide to the end
user a fresh baked authentic French or other hard crusted bread which requires
a minimum of time and effort and, yet, provides a delicious, apparently freshly
baked product, a sense of accomplishment of baking the same on the premises, the
aroma of a fresh baked bread, and a freshness and authenticity which far exceeds
currently-available, fully-baked and then frozen-for-later reheating or browning
bread products.
Fully-baked and then frozen breads which are already commercially
available suffer from the following disadvantages, inter alia, with respect to
the partially-baked bread product disclosed and claimed herein: the freshness of
the finished product, after completion of baking, is far longer than already fully
baked products; and, there is no separation of the crust from the inside dough
during finish baking with the partially-baked bread product disclosed herein. In
previously available hard crust products which are meant to be served long after
baking, there is a separation between the hard crust and the inside dough. The
present invention, on the other hand, exhibits no such bread dough to hard crust
separation. When stored at about 0°F (-17.8°C), the partially-baked bread product
of this invention has a shelf life of about 5 to 6 months. The shelf-life of the
partially-baked bread, when thawed and stored in a refrigerator is about eight
days, and the shelf life of the product when thawed and left at about room temperature
is about 48 hours. All of these represent improved shelf life with respect to previously
available hard crusty or specialty bread.
Also, according to the present invention, the freshness, which usually
corresponds to the amount of CO&sub2; and water or humidity retained in the product,
is also far improved over the previously available products.
SUMMARY OF THE INVENTION
The present invention relates to a crusty or specialty bread and
a method of manufacturing the same which has an improved shelf life and is finished
baked on the site of the ultimate end user. The moisture content of the partially-baked
product is at least about 20% greater than the moisture content of a fully-baked
and then frozen product and this, too, is a tremendous advantage to the present
product. Basically, as will be explained more fully hereinafter, the bread is prepared
by mixing dry ingredients with water and a leavening agent, preferably yeast.
A taste enhancing ingredient, such as salt, is preferably added. Preferably, the
temperature of the ingredients is adjusted so that the temperature of the dough
is about 78°F (25.6°C) after the mixing process is completed. Next, the dough is
rested to let the fermentation start. This is typically done at about an ambient
humidity and temperature for about 10 minutes.
Next, the dough is divided, weighed, lightly rounded, and then left
to rest for a second rising. It is then flattened to expel carbon dioxide. The
dough is then molded into the dough's final form and left to rest in a proofing
atmosphere for a final rising.
The dough is proofed at a relative humidity which is preferably between
about 65 and 75% and at a temperature of from about 80 to 85°F (26.7 to 29.4°C).
Of course, lower humidity and/or temperature could be employed if extended proofing
times were tolerable. The proofing step should be effective to obtain a proofed
dough volume of from 2.0 to 3.0, preferably about 2.5, times the preproofed dough
volume.
Next, the dough is baked. This is done by placing the proofed dough
in an oven which has been preheated to about 350° to 400°F (176.7 to 204.4°C),
according to the size of the loaves. The oven is then injected with a jet of steam
in order to keep the skin of the dough plastic, which condition will contribute
to the volume of the bread and accentuate the definition of any slash marks on
the top of the loaf. Then, the dough is baked to achieve a 78 to 90%, preferable
about an 84%, pre-baked product. The length of baking time will, of course, depend
on the size and shape of the dough. Before the completed baking time, however,
the oven is given a second jet of steam, thus allowing the partially-baked product
to retain a substantial amount of moisture, which is at least about 20% more than
a fully baked product.
The bread is then cooled for a period of at least about 15 minutes,
depending on size. Then, the bread is frozen, again for a time depending on the
size of the loaves. Finally, the product is packaged and stored at 0°F.
DETAILED DESCRIPTION OF THE INVENTION AND THE PREFERRED EMBODIMENT
The purpose of the method of the invention disclosed herein is to
enable neighborhood bakeries, supermarket in-store bakeries, and specialty and
gourmet shops to offer the end user or consumer a fresh baked line of authentic
French and other hard crusted breads. The purpose of the present invention is accomplished
while maintaining the freshness and authenticity of the product both before final
baking and after the final baking. The method only requires about 10 to 15 minutes
to "finish off" the bread by baking the partially-baked bread in any type of commercial
or even residential oven, as, for example, convection, semi-industrial, domestic,
etc. (not a microwave, however). Also of importance, the present invention does
not require the use of specially skilled labor to provide the desired product.
At a temperature of about 350° to 375°F (176.7 to 190.6°C) the processed
and partially-baked bread may be baked to a finished product either from a frozen
or a thawed state. Irrespective of the state that the partially-baked product
is in when it is sought to be "finished off", the result is a spectacular, fresh
baked product that retains its freshness for up to 24 hours. Unlike products advertised
as "brown and serve", the bread product produced herein has been fully proofed
under controlled conditions, has been cut, steamed and precisely pre-baked to
only about 78 to 90% of a finished baked product in properly humidity-controlled,
steam-providing ovens. In this manner the ultimate finisher of the product is
doing the baking to a finished edible product and the freshness is superior. The
presence of a freshly baked aroma is also significant.
A commercial batch of the product is prepared with 100 pounds of
flour constituting the base. The particular composition of one embodiment of the
flour is 75 pounds of patent flour, representing an 75% base flour and 25 pounds
of pastry flour, representing 25% flour. The percentages just described add up
to a total of 100% or 100 pounds of the flour composition. As is usual in commercial
baking, the other ingredients are based on percentages of the total flour which
percentages are easily converted into pounds. The flour is first dry mixed to
form the flour composition. Then about 57 to 60 pounds of water, as the hydration
agent, is added to the dry mixture along with about 1.8 pounds of yeast representing
1.8 percent leavening agent, 1.5 pounds of salt, representing the 1.5% taste or
flavor enhancer, and 0.75 pounds of dough conditioner.
The dry ingredients, except the salt, along with the water are mixed
in a conventional manner to produce a homogenous dough composition. Mixing takes
about 14 minutes. Then salt is added for the last 4 minutes of mixing. The temperature
of the ingredients, along with a consideration of the ambient temperature, is adjusted
so that the dough composition, after mixing, is at a temperature of about 78°F.
Now, the dough is rested for about 10 minutes in order to allow the
fermentation to commence and this is done in at ambient temperature, typically
about 80 to 85°F (26.7 to 29.4°F).
Once the dough has risen for the first time it is then divided, weighed,
lightly rounded, and then left to rest for a second rising for a period of time,
typically varying from between about 12 to 18 minutes. It is then flattened, molded
into the dough's final form and then left to rest in a proofing atmosphere for
the final rising until it reaches the desired density.
In the proofing stage, the humidity will usually range between about
65% and about 80% and the temperature will usually range between about 80 to 85°F,
(26.7 to 29.4°C). This readily brings the dough to a final pre-baked density,
having a volume of from 2.0 to 3.0, preferably 2.5, times the preproofed volume.
The dough is now ready for near complete baking. The dough is placed
in a preheated oven at a temperature of about 350° to 400°F (176.7 to 204.4°C)
according to the size of the loaves. During the initial stages of baking a first
stream of low-pressure, saturated steam is injected into the oven, preferably this
period of steam injection lasts for at least 30 seconds. It has been found that
this initial steam maintains the skin of the dough in a plastic condition while
the dough is expanding in the oven (i.e. undergoes oven spring).
The initial flow of steam is interrupted and baking of the dough
continues to obtain a total period of at least 10 minutes, usually about 12 to
25 minutes; the exact time depending upon the size and shape of the dough. During
the latter stage of baking a second stream of low-pressure, saturated steam is
injected into the oven. Typically, this second stream is injected for a period
of at least 20 seconds. Typically, the second steam injection step begins about
three minutes before the end of the baking cycle. Thereafter, the dough is removed
from the oven after only 78 to 90%, preferably about 84%, of the time required
to obtain a fully-baked bread. The second stream of injection and the total baking
time is selected to obtain a moisture content in the partially-baked bread which
is at least about 20% greater than the moisture content of a fully-baked bread.
The partially-baked bread is removed from the oven and cooled to
about ambient temperature. Cooling will, depending on the size of the bread, usually
take about 15 to 45 minutes. The cooled bread is then quickly frozen to below
0°F (-17.7°C) using freezing equipment such as a flash and/or blast freezer. It
has been found that a distinct cooling step is necessary in order to uniformly
distribute moisture between the crust and the interior of the bread and to create
elasticity in the crust. The cooled, partially-baked bread of this invention possesses
resistance to freezer distortion and the resulting frozen product can be fully
baked after extended frozen storage without encountering crust deformation or separation
between the crust and the internal crumb.
Finally, the thoroughly frozen product is packaged in a suitable
wrapper (e.g. plastic film) for storage at about 0°F.
One of the truly unique aspects of the processing is the last injection
of steam before the end of the baking period. This enables the end-user to have
a product with a completely sealed crust that will not separate from the loaf.
Undesirable separation can be observed in many of the so-called "brown and serve"
products.
It will be appreciated that the particular description of the embodiments
disclosed herein are only representative of the invention. Skilled bakers will,
basis the disclosure set forth above, be readily able to adjust formulations and
processing conditions to practice my invention in accordance with their own particular
needs. The true scope of the invention to which I am entitled to is shown by the
claims and their legal equivalents.
