Abstract
ABSTRACT OF THE DISCLOSURE
Oriental-style breading crumbs, useful for application to a variety of fried food products, are formed by a novel procedure in which a leavened dough is first formed by a continuous mixing process, the dough is stretched to elongate the pores in the dough, the stretched dough is baked while maintained in an elongated condition, and the baked dough is comminuted to form the crumbs. The Oriental-style breading crumbs which are formed by this procedure may have less fragility and a more uniform size and splinter shape and impart greater crispiness to food products than crumbs produced by prior art procedures.

Description
1 1~13~)~
PRODUCTION OF ORIENTAL-STYLE BREADING CRUMBS
The present invention relates to the production of oriental-style breading crumbs.
Oriental-style breading crumbs, also referred to as Japanese-style breading crumbs and Panko-style breading crumbs, are characterized by an elongate shape having a coarse, splintered appearance. These breading crumbs are used to provide a tender texture and crispiness to a variety of fried food products, such as, seafoods, poultry and red meat, which is considered desirable.
These breading crumbs conventionally are formed 15 by a procedure which involves a conventional proofed dough preparation followed by rapid baking using the electrical resistance of the dough as a means of heating.
Bread flour, optionally in admixture with rice 10ur, is combined with water, salt and yeast, and optionally sugars and shortening, in proportions normally used in conventional bread making. The ingredients are mixed in a standard batch dough mixer for about 5 to 8 minutes and the dough batch so formed is transferred to a container for a bulk fermentation period of about 30 to 60 minutes.
The dough then is divided into five to seven pound portions and placed in rectangular wooden containers in which the longer dimension is vertical and approximately 18 inches with the horizontal surface being about 6 inches x 10 inches in cross section. The two larger vertical faces of the container are covered with 3 a sheet metal, which acts as an electrical conductor.
The dough is allowed to proof in the containers for an hour, during which period the dough expands vertically. Baking is effected by passing an electrical current through the proofed dough for about 12 minutes, ~3~
,,, , i1 ~ lSl~
which further elongates the dough by expansion of the yeast-formed gas cells and formation of water vapour in the porous dough. The cooked dough is removed from the containers after a brief cooling period and allowed to fully cool, evaporate and stale overnight. The bread is then ground to the required mesh size and dried to the desired final moisture content.
The present invention is concerned with an improved process for the formation of oriental-style breading crumbs which is continuous in nature, involves considerably shorter time periods and greatly reduced space and labour requirements than the prior art, and is more versatile than the prior art with respect to the form of the product which is produced.
In accordance with the present invention, a leavened dough first is formed from bread forming ingredients, a tow is formed from the dough, the tow is stretched to effect elongation of the pores within the leavened dough, the stretched dough i~ baked while maintaining the dough in its stretched form, the baked dough is comminuted to form the breading particles, and the comminuted particles are dried to the desired moisture level.
The initial bread-forming ingredients used in the process of the invention may comprise any of the 25 components conventionally used in bread-making and itemized under the Standards of Identity, U.S. FDA
Regulations 21 C.F.R. 136.110 to .180 inclusive. The basic components of any dough are flour and water, the term "flour" including farinaceous flours used alone or 30 in combination with other flours and meals, such as, the permitted materials outlined in 21 C.F.R. 137.105 to .350 inclusive, as well as those of legumes, rye, sorghum and rice. Usually the flour used comprises a major proporti~n of hard wheat flour.
Varying amounts of dough-fGrming components may be used, usually including sugar, salt and vegetable I i&~
shortening in varying proportions, depending on the characteristics desired in the product and the flour used. Other bread-forming components which may be used include oxidizing, maturing and improving agents, such as, potassium bromate, azodicarbonamide, cysteine hydrochloride and ascorbic acid. Yeast, and amylolytic and proteolytic enzymes also may be included, to modify texture and flavour in the product. Emulsifiers and cell-wall improvers may be used.
Leavening of the dough may be effected in this invention utilizing any convenient leavening agent. It is preferred to effect the leavening using gaseous materials, such as, carbon dioxide, nitrogen, air, or mixtures of gases, alone or in combination with chemical leavening using leavening gas-producing chemicals. Such leavening gas-producing chemicals include a combination of sodium bicarbonate and sodium aluminum phosphate or a combination of sodium bicarbonate and monocalcium phosphate.
Yeast leavening may be used but is less preferred since longer holding times are required, thereby increasing equipment space requirements, and a lesser quality of product is obtained. The presence of more than small quantities of salt tends to inhibit the 25 leavening effect of yeast. Where leavening i5 effected using gaseous materials, more than the usual small quantities of salt may be used, enabling variations in flavour to be achieved.
Further, where leavening is effected using 30 gaseous materials, alone or in combination with chemical leavening, as in the preferred embodiment of the invention, yeast, however, may be used as a flavour enhancer in the dough.
The various proportions of dough-forming 35 ingredients used to form the dough depend on the properties desired, the flour used and also on the nature and choice of components. One suitable composition of ingredients, exclusive of water, which may be utilized in this invention, as a dry mi~, includes:
1 16~3~)~
Hard wheat flour - 100 parts by weight Sugar - up to about 5~ by weight of flour Salt - up to about 5% by weight of flour Vegetable shortening - up to about 8% by weight of flour In addition, one or more of the following optional components may be present, based on the weight of flour:
Yeast - 0 to about 4% by weight Yeast food - about 0.2 to about 0.35% by weight when yeast is present Corn sugar - 0 to about 1.0% by weight Mono and/or diglycerides - 0 to about 0.5% by weight TWEEN
surfactant - 0 to about 1.0% by weight Another suitable composition of ingredients also useful as a dry mix in this invention, utilizing a mixture of flours, may comprise:
Hard wheat flour - about 67 parts by weight Soft wheat flour - about 33 parts by weight Sugar - up to about 5~ by weight of flour Vegetable shortening - up to about 8~ by weight of flour Salt - up to about 5~ by weight of flour In addition, one or more of the following optional components may be present in the latter dry mix, based on the weight of flour:

.
Blish)/100 lbs of flour Mono and/or diglycerides - 0 to about 0.5% by weight "Tween"
5 surfactant - 0 to about 1.0~ by weight Corn sugar - 0 to about 1.0% by weight Products made from the preceding compositions, while use~ul in certain end uses, are somewhat inferior, in that they lack fry tolerance, lack flavour, have inferior structure and tend to have a dark appearance.
In a preferred embodiment of this invention, flavour-enhancing and texture-modifying premixes or brews are used to improve texture, flavour, fry tolerance and structure of the product and to provide a wide variety of 15 properties. One or more of these properties may be improved over the corresponding property of the oriental-style crumb produced by conventional procedures.
The flavour-enhancing and texture-modifying premixes include enzyme systems which are used in a 20 concentrated brew along with a minor proportion, usually less than about 20~ by weight, of the total proportion of flour used and a major proportion, usually about 50 to 80% by weight, ~f the inlet moisture. The brew is fermented for a short perio~ of time, typically about 30 25 minutes at about 90 to 105F, during which time the amylases and proteases have suficient timeOto modify the flour and provide a desired texture and other properties in the final product.
A brew mix which may be used in this way 30 contains, based on total flour in the overall dough-forming composition:
Hard wheat flour - about 5 to about 20% by weight Water - about 35 to about 55% by weight Proteolytic enzyme - about 25,000 to about 85,000 H.U.per 100 lb of flour Amylolytic enzyme - about 1250 to about 8000 SKB
units per 100 lb of flour The above-described brew mix, after completion of the fermenting period, is used in this embodiment of the invention in association with such addit-ional water as may be required to provide the desired overall moisture content and with a dry mix comprising, by weight of total flour in the overall dough-forming composition:
Hard wheat flour - about 80 to about 95% by weight Vegetable shortening - up to about 8~ by weight Chemical leavening agents - up to about 4% by weight Sugar - up to about 5% by weight Salt - up to about 5% by weight This dry mix may also contain optional ingredients, based on total flour in the overall dough-forming composition, namely:
Mono and/or diglycerides - 0 to about 0~5% by weight Tween surfactant - O to about 1.0% by weight Corn sugar - 0 to about 1.0% by weight The dough-forming ingredients are mixed together to form a dough. In a preferred embodiment of the procesn of this invention, the dough-forming ingredients are fed to inlets at one end of a continuous mixing zone capable of plug flow therethrough. The mixing zone may take the form of an elongate screw-type mixer-extruder, suitably modified to provide the required processing conditions therein. The dough-forming components are fed to one end of the mixer in relative proportions suitable to provide an overall moisture content of intermixed components of about 38 to about 50%
by weight, preferably about 42 to about 47~ by weight.
30 The dry mix, water, and any flavour-enhancing and texture modifying ferment, are usually separately fed to the mixer.
Within the mixing zone, the dough-forming ingredients are continuously intermixed while they are 35 conveyed from one end of the mixing zone to the other, over a period of time about 20 to about 120 seconds, preferably about 30 to about 60 seconds.
A plurality of spaced gaseous inlets is provided along the length of the mixing ~one and a gaseous leavening material, or mixture of such gaseous materials, is injected into the mix through the openings.
Carbon dioxide usually is used as the gaseous leavening material, often in admixture with nitrogen, although other gaseous leavening materials may be used, including air and oxygen. The total gas feed to the ~ixing zone is in the range of about 1.0 to about 10 SCF, preferably about 2 to about 4 SCF, per 100 lb of dough.
The carbon dioxide, or other gaseous material, may be used as the sole leavening agent, although it is usually preferred in the continuous process mode of the invention to employ chemical leavening agents in addition to the carbon dioxide. When such chemical leavening agents are present, the carbon dioxide tends to stabilize the pore structure.
The dough-forming components and the injected gas, as well as in-situ produced gas when the chemical leavening agents are used, are subjected to high shear forces within the mixing zone, sufficient to cause simultaneous uniform mixing of the components and dispersion of the gases throughout the mix. The work done ~n the dough within the mixing zone varies from about 4 to about 16 watt hr/lb of dough, preferably about 8 to about 12 watt hx/lb.
The mix of dough-forming components and inert gas usually is heated within the mixing zone for at least a major proportion, typically about 75~, of the length of the mixing zone to cause partial swelling of starch granules contained in the dough-forming components.
The temperature in the mixing zone is maintained sufficiently high that the heat applied, combined with that resulting from the high shear mixing, results in a dough emerging from the mixing zone having a temperature of about 85 to about 120F, preferably about 35 95 to about 105F.
The dough resulting from the operations in the continuous mixing zone is extruded therefrom under a back pressure which is usually in the range of about 50 to about 500 psig, and is preferably a relatively low back .
pressure in the range of about 75 to about 120 psig, achieved by suitable design of the extrusion nozzle. The mixing operations effected in the mixing zone are controlled by the above-described parameters to result in an extruded dough having a viscosity comparable to that achieved from a conventional batch dough-forming procedure.
The dough formed by the above-described continuous mixing procedure is extruded from the mixing zone as a continuous tow, which generally has a transverse dimension of about 2 to about 6 inches.
The extruded dough tow is allowed to "relax"
for a time period sufficient to achieve an extensible dough. Where leavening is effected using gaseous leavening agents, preferably also with chemical leavening agents, this relaxation time usually is about 1 to about 7 minutes, typically about 2 minutes. Where, however, leavening is achieved using yeast, a longer relaxation period is required followed by a proofing period~
20 The stretching of the extruded dough tow may be effected in a batch manner or, more preferably, in a continuous manner.
In the batch procedure, the tow is cut into convenient lengths, usually about 6 to about 12 inches, 25 and the individual lengths are longitudinally stretched, usually to about 3 to about 8 times their original length, to effect elongation of the pores within the dough. The degree of stretching of the tow lengths is critical to the invention, in that if the stretching is 30 insufficient, then splintering of baked dough to form the Oriental-style crumbs does not occur, while if the stretching is too great, then the tow lengths break and the porous structure collapses.
This batch procedure is somewhat 35 disadvantageous in that it is difficult to control the degree of stretch and hence the consistency of finished product, and loaves result which leave ends which are not splintered and represent waste. For these reasons, it i3 preferred to utilize a continuous procedure, which i ~13~5 produces a consistent product and no unstretched portions are found in loaf ends.
In the continuous procedure, the dough tow is maintained as a continuous length and is stretched over a series of moving belts of successively increasing conveyor speed to effect a stretch of usually about 3 to about 8 times over a period of usually abou~ 30 seconds to about 6 minutes. The relative surface speeds of the belts depend on the degree of stretch required, the rate of production of the dough from the mixing zone and the throughput of dough required.
For example, for a dough tow stretch of 5 times and using 5 conveyors, the initial belt speed may vary from about 1.25 to about 16 ft/min, typically about 2.5 ft/min, increasing uniformly to a final belt speed of about 6.25 to about 80 ft/min, typically about 12.5 ft/min. At such a final belt speed, a typical dough throughput is about Z00 to about 3000 lb/hr.
The dimensions of the stretched tow which results from this stretching operation depend on the initial dimensions and the degree of stretching which is effected. Usually, the stretched tow is about 1 to about 5 inches wide and about ~ to about 1~ inches thick.
The stretched dough next is baked. The baking of the stretched tow may be effected in any desired manner, including infrared baking, microwave baking and a combination of the two. When infrared baking is employed, either alone or in combination with microwave baking, the bread tow must be in a twisted form to 30 maintain the desired porous structure during dough baking and to enable splintering of the baked tow to be effected.
Twisting of the dough prior to baking may be effected on a continuous tow, if such is formed in the 35 continuous process discussed above. Alternatively, where the batch process is used, the stretched pieces are twisted together in pairs or greater numbers. The number of twists effected depends, to some extent, on the length of the individual tow pieces, and usually is about 4 to about 10 times. Such twisting preferably is effected after initial stretching, although the process is effective if the twisting is carried out prior to stretching.
Where microwave baking alone is used, the baking may be effected on a continuous stretched tow without twisting and hence is preferred.
When the baking is effected wholly in an infra-red baking oven, the oven temperature may vary from about 325 to about 400F to result in an internal temperature of baked dough of about 175 to about 210F.
The bake time required is usually about 25 to about 40 minutes.
When the baking is effected by a combination of microwave baking followed by infrared baking, the microwave baking operation is effected at a microwave energy input of about 1.0 to about 2.0 KWH/100 lb of dough for a time sufficient to result in an internal temperature of about 125 to about 175F, usually about 60 to about 180 seconds. During the microwave baking, an aix flow is maintained to remove moisture evaporated in the baking process. Dough passes through the microwave oven at a throughput rate of about 50 to about 200 lb of dough per hour.
Following completion of the microwave baking step, the partially-baked dough is subjected to infra-red oven baking to complete the baking step. The oven baking may be effected at a temperature in the range of about 325F to about 400F for a time sufficient to result in a 30 dough temperature of about 175 to about 210F, preferably about 190F, generally in about 10 to about 25 minutes.
In effecting wholly microwave baking on stretched dough, the conveyor belt of the oven is xun faster than the rate of feed of the tow, so as to maintain the tension in the elongate direction of the tow and thereby maintain the elongation of the pores during gas expansion induced by the baking. The differential in speed is such that the conveyor belt of the microwave --oven moves at about 5 to about 20~ faster than the feed rate.
Preferably, when this procedure is adopted, chemical leavening agents are used in the dough-forming components, such chemical leavening agents being chosen to have residual leavening activity during the microwave baking operation, so as to counteract the compression applied to the pores by the stretching step.
The microwave energy input is about 1.7 to about 3.7 KWH/100 lb of dough for a time to result in an internal temperature of preferably about 175F to about 210F, usually in about 10 to about 300 seconds. The microwave initially sets the structure of the stretched tow and then bakes the dough to a fully baked state.
During the microwave baking, an air flow is maintained to remove moisture evaporated in the baking process. Moisture loss during the microwave baking varies rom about 3% to about 12% by weight. Such moisture removal is neces~ary in order to reach the desired internal temperature of the fully cooked product.
Following completion of the baking of the dough, the loaves are allowed to stand for a period of time to permit the loaves to cool. The cooling may be effected, for microwave-baked loaves, for about 6 minutes 25 to about 4 hours and for oven-baked loaves, for about 1 to about 24 hours, usually by standing on perforated racks.
As the tow emerges baked from the oven, it lacks the mechanical strength to be shredded or ground 30 without compaction. ~he short cooling period permits the bread to become more rigid and hence able to undergo shredding or grinding.
The cooling period which is used in the preferred embodiment of the invention contrasts markedly 35 with the procedure required when the conventional procedure is used, in that the prior art requires a long staling period, typically about 18 hours, before the bread becomes rigid enough for grinding. In contrast, the rapid process used in this invention does not give t 16~3~5 rise to the formation of antistaling components and hence the baked dough rapidly achieves a staled condition sufficient to permit shredding to a spllnter shape only a short time after completion of baking.
The cooled loaves next are ground to cause comminution of the loaves and formation of Oriental-style breading crumbs. The dried breading crumbs formed in this way have an elongate splinter shape, characteristic of Oriental-style breading crumbs. The crumbs are dried to a moisture level below about 12 wt.~, preferably about 3 to about 7 wt.%.
The properties of the product which results from the process of the invention may approximate those of the product produced by the conventional process.
15 However, by varying the ingredients and processing conditions, the crumbs may have less fragility and a significantly improved shelf life when compared with the prior art, and may have a variable browning rate and/or a variable texture.
The invention is il~ustrated by the following Examples:
Example 1 This Example illustrates the preparation of Oriental-style breading crumbs wherein baking is effected using partially microwave baking and partially infrared baking.
Two separate compositions were prepared, namely a dry mix and a liquid brew. The compositions had the following constituents:

The components were continuously intermixed during passage ~rom one end of the extruder to the other over a period of about 35 `seconds. Carbon dioxide was fed into the extruder at six different locations along the length of the extruder at a rate of 3.4 SCF/100 lb 20 dough while the extruder was heated to result in a dough having a temperature of 110F at the exit of the extruder. Work was applied to the dough during formation thereof and passage through the extrud~r of 10 watt hr/lb of dough and a back pressure of 110 psig existed at the 25 extruder outlet orifice.
A continuous dough tow of about 3 inches in diameter was extruded from the extruder and cut into 9 inch length loaves (about 1 lb). These loaves were stretched to about 5 times their original length. Two 30 pieces were placed side by side, twisted together about 7 times and then baked. The baking was effected using a successive combination of microwave and infrared heating.
The microwave baking was effected to set the dough and maintain the desired pore structure at an 35 energy input of 1.6 KWH/100 lb dough while a flow of air at a temperature of about 250F was passed through the oven to remove the moisture. The microwave baking was effected to result in an internal temperature of the dough of 150F.
The infrared baking of the microwave-baked dough was effected at an oven temperature of about 350F
for 15 minutes to result in an internal temperature of the baked dough of 190F.
The loaves were then cooled for about 60 minutes, ground to the desired particle size and dried to a moisture content of about 5% by weight. The resulting crumbs had the characteristic shape of the Oriental-style breading crumb and had the following properties:

PRODUCTION OF ORIENTAL-STYLE BREADING CRUMBS
The present invention relates to the production of oriental-style breading crumbs.
Oriental-style breading crumbs, also referred to as Japanese-style breading crumbs and Panko-style breading crumbs, are characterized by an elongate shape having a coarse, splintered appearance. These breading crumbs are used to provide a tender texture and crispiness to a variety of fried food products, such as, seafoods, poultry and red meat, which is considered desirable.
These breading crumbs conventionally are formed 15 by a procedure which involves a conventional proofed dough preparation followed by rapid baking using the electrical resistance of the dough as a means of heating.
Bread flour, optionally in admixture with rice 10ur, is combined with water, salt and yeast, and optionally sugars and shortening, in proportions normally used in conventional bread making. The ingredients are mixed in a standard batch dough mixer for about 5 to 8 minutes and the dough batch so formed is transferred to a container for a bulk fermentation period of about 30 to 60 minutes.
The dough then is divided into five to seven pound portions and placed in rectangular wooden containers in which the longer dimension is vertical and approximately 18 inches with the horizontal surface being about 6 inches x 10 inches in cross section. The two larger vertical faces of the container are covered with 3 a sheet metal, which acts as an electrical conductor.
The dough is allowed to proof in the containers for an hour, during which period the dough expands vertically. Baking is effected by passing an electrical current through the proofed dough for about 12 minutes, ~3~
,,, , i1 ~ lSl~
which further elongates the dough by expansion of the yeast-formed gas cells and formation of water vapour in the porous dough. The cooked dough is removed from the containers after a brief cooling period and allowed to fully cool, evaporate and stale overnight. The bread is then ground to the required mesh size and dried to the desired final moisture content.
The present invention is concerned with an improved process for the formation of oriental-style breading crumbs which is continuous in nature, involves considerably shorter time periods and greatly reduced space and labour requirements than the prior art, and is more versatile than the prior art with respect to the form of the product which is produced.
In accordance with the present invention, a leavened dough first is formed from bread forming ingredients, a tow is formed from the dough, the tow is stretched to effect elongation of the pores within the leavened dough, the stretched dough i~ baked while maintaining the dough in its stretched form, the baked dough is comminuted to form the breading particles, and the comminuted particles are dried to the desired moisture level.
The initial bread-forming ingredients used in the process of the invention may comprise any of the 25 components conventionally used in bread-making and itemized under the Standards of Identity, U.S. FDA
Regulations 21 C.F.R. 136.110 to .180 inclusive. The basic components of any dough are flour and water, the term "flour" including farinaceous flours used alone or 30 in combination with other flours and meals, such as, the permitted materials outlined in 21 C.F.R. 137.105 to .350 inclusive, as well as those of legumes, rye, sorghum and rice. Usually the flour used comprises a major proporti~n of hard wheat flour.
Varying amounts of dough-fGrming components may be used, usually including sugar, salt and vegetable I i&~
shortening in varying proportions, depending on the characteristics desired in the product and the flour used. Other bread-forming components which may be used include oxidizing, maturing and improving agents, such as, potassium bromate, azodicarbonamide, cysteine hydrochloride and ascorbic acid. Yeast, and amylolytic and proteolytic enzymes also may be included, to modify texture and flavour in the product. Emulsifiers and cell-wall improvers may be used.
Leavening of the dough may be effected in this invention utilizing any convenient leavening agent. It is preferred to effect the leavening using gaseous materials, such as, carbon dioxide, nitrogen, air, or mixtures of gases, alone or in combination with chemical leavening using leavening gas-producing chemicals. Such leavening gas-producing chemicals include a combination of sodium bicarbonate and sodium aluminum phosphate or a combination of sodium bicarbonate and monocalcium phosphate.
Yeast leavening may be used but is less preferred since longer holding times are required, thereby increasing equipment space requirements, and a lesser quality of product is obtained. The presence of more than small quantities of salt tends to inhibit the 25 leavening effect of yeast. Where leavening i5 effected using gaseous materials, more than the usual small quantities of salt may be used, enabling variations in flavour to be achieved.
Further, where leavening is effected using 30 gaseous materials, alone or in combination with chemical leavening, as in the preferred embodiment of the invention, yeast, however, may be used as a flavour enhancer in the dough.
The various proportions of dough-forming 35 ingredients used to form the dough depend on the properties desired, the flour used and also on the nature and choice of components. One suitable composition of ingredients, exclusive of water, which may be utilized in this invention, as a dry mi~, includes:

Hard wheat flour - 100 parts by weight Sugar - up to about 5~ by weight of flour Salt - up to about 5% by weight of flour Vegetable shortening - up to about 8% by weight of flour In addition, one or more of the following optional components may be present, based on the weight of flour:

Blish)/100 lbs of flour Mono and/or diglycerides - 0 to about 0.5% by weight "Tween"
5 surfactant - 0 to about 1.0~ by weight Corn sugar - 0 to about 1.0% by weight Products made from the preceding compositions, while use~ul in certain end uses, are somewhat inferior, in that they lack fry tolerance, lack flavour, have inferior structure and tend to have a dark appearance.
In a preferred embodiment of this invention, flavour-enhancing and texture-modifying premixes or brews are used to improve texture, flavour, fry tolerance and structure of the product and to provide a wide variety of 15 properties. One or more of these properties may be improved over the corresponding property of the oriental-style crumb produced by conventional procedures.
The flavour-enhancing and texture-modifying premixes include enzyme systems which are used in a 20 concentrated brew along with a minor proportion, usually less than about 20~ by weight, of the total proportion of flour used and a major proportion, usually about 50 to 80% by weight, ~f the inlet moisture. The brew is fermented for a short perio~ of time, typically about 30 25 minutes at about 90 to 105F, during which time the amylases and proteases have suficient timeOto modify the flour and provide a desired texture and other properties in the final product.
A brew mix which may be used in this way 30 contains, based on total flour in the overall dough-forming composition:
Hard wheat flour - about 5 to about 20% by weight Water - about 35 to about 55% by weight Proteolytic enzyme - about 25,000 to about 85,000 H.U.per 100 lb of flour Amylolytic enzyme - about 1250 to about 8000 SKB
units per 100 lb of flour The above-described brew mix, after completion of the fermenting period, is used in this embodiment of the invention in association with such addit-ional water as may be required to provide the desired overall moisture content and with a dry mix comprising, by weight of total flour in the overall dough-forming composition:
Hard wheat flour - about 80 to about 95% by weight Vegetable shortening - up to about 8~ by weight Chemical leavening agents - up to about 4% by weight Sugar - up to about 5% by weight Salt - up to about 5% by weight This dry mix may also contain optional ingredients, based on total flour in the overall dough-forming composition, namely:
Mono and/or diglycerides - 0 to about 0~5% by weight Tween surfactant - O to about 1.0% by weight Corn sugar - 0 to about 1.0% by weight The dough-forming ingredients are mixed together to form a dough. In a preferred embodiment of the procesn of this invention, the dough-forming ingredients are fed to inlets at one end of a continuous mixing zone capable of plug flow therethrough. The mixing zone may take the form of an elongate screw-type mixer-extruder, suitably modified to provide the required processing conditions therein. The dough-forming components are fed to one end of the mixer in relative proportions suitable to provide an overall moisture content of intermixed components of about 38 to about 50%
by weight, preferably about 42 to about 47~ by weight.
30 The dry mix, water, and any flavour-enhancing and texture modifying ferment, are usually separately fed to the mixer.
Within the mixing zone, the dough-forming ingredients are continuously intermixed while they are 35 conveyed from one end of the mixing zone to the other, over a period of time about 20 to about 120 seconds, preferably about 30 to about 60 seconds.
A plurality of spaced gaseous inlets is provided along the length of the mixing ~one and a gaseous leavening material, or mixture of such gaseous materials, is injected into the mix through the openings.
Carbon dioxide usually is used as the gaseous leavening material, often in admixture with nitrogen, although other gaseous leavening materials may be used, including air and oxygen. The total gas feed to the ~ixing zone is in the range of about 1.0 to about 10 SCF, preferably about 2 to about 4 SCF, per 100 lb of dough.
The carbon dioxide, or other gaseous material, may be used as the sole leavening agent, although it is usually preferred in the continuous process mode of the invention to employ chemical leavening agents in addition to the carbon dioxide. When such chemical leavening agents are present, the carbon dioxide tends to stabilize the pore structure.
The dough-forming components and the injected gas, as well as in-situ produced gas when the chemical leavening agents are used, are subjected to high shear forces within the mixing zone, sufficient to cause simultaneous uniform mixing of the components and dispersion of the gases throughout the mix. The work done ~n the dough within the mixing zone varies from about 4 to about 16 watt hr/lb of dough, preferably about 8 to about 12 watt hx/lb.
The mix of dough-forming components and inert gas usually is heated within the mixing zone for at least a major proportion, typically about 75~, of the length of the mixing zone to cause partial swelling of starch granules contained in the dough-forming components.
The temperature in the mixing zone is maintained sufficiently high that the heat applied, combined with that resulting from the high shear mixing, results in a dough emerging from the mixing zone having a temperature of about 85 to about 120F, preferably about 35 95 to about 105F.
The dough resulting from the operations in the continuous mixing zone is extruded therefrom under a back pressure which is usually in the range of about 50 to about 500 psig, and is preferably a relatively low back .
pressure in the range of about 75 to about 120 psig, achieved by suitable design of the extrusion nozzle. The mixing operations effected in the mixing zone are controlled by the above-described parameters to result in an extruded dough having a viscosity comparable to that achieved from a conventional batch dough-forming procedure.
The dough formed by the above-described continuous mixing procedure is extruded from the mixing zone as a continuous tow, which generally has a transverse dimension of about 2 to about 6 inches.
The extruded dough tow is allowed to "relax"
for a time period sufficient to achieve an extensible dough. Where leavening is effected using gaseous leavening agents, preferably also with chemical leavening agents, this relaxation time usually is about 1 to about 7 minutes, typically about 2 minutes. Where, however, leavening is achieved using yeast, a longer relaxation period is required followed by a proofing period~
20 The stretching of the extruded dough tow may be effected in a batch manner or, more preferably, in a continuous manner.
In the batch procedure, the tow is cut into convenient lengths, usually about 6 to about 12 inches, 25 and the individual lengths are longitudinally stretched, usually to about 3 to about 8 times their original length, to effect elongation of the pores within the dough. The degree of stretching of the tow lengths is critical to the invention, in that if the stretching is 30 insufficient, then splintering of baked dough to form the Oriental-style crumbs does not occur, while if the stretching is too great, then the tow lengths break and the porous structure collapses.
This batch procedure is somewhat 35 disadvantageous in that it is difficult to control the degree of stretch and hence the consistency of finished product, and loaves result which leave ends which are not splintered and represent waste. For these reasons, it i3 preferred to utilize a continuous procedure, which i ~13~5 produces a consistent product and no unstretched portions are found in loaf ends.
In the continuous procedure, the dough tow is maintained as a continuous length and is stretched over a series of moving belts of successively increasing conveyor speed to effect a stretch of usually about 3 to about 8 times over a period of usually abou~ 30 seconds to about 6 minutes. The relative surface speeds of the belts depend on the degree of stretch required, the rate of production of the dough from the mixing zone and the throughput of dough required.
For example, for a dough tow stretch of 5 times and using 5 conveyors, the initial belt speed may vary from about 1.25 to about 16 ft/min, typically about 2.5 ft/min, increasing uniformly to a final belt speed of about 6.25 to about 80 ft/min, typically about 12.5 ft/min. At such a final belt speed, a typical dough throughput is about Z00 to about 3000 lb/hr.
The dimensions of the stretched tow which results from this stretching operation depend on the initial dimensions and the degree of stretching which is effected. Usually, the stretched tow is about 1 to about 5 inches wide and about ~ to about 1~ inches thick.
The stretched dough next is baked. The baking of the stretched tow may be effected in any desired manner, including infrared baking, microwave baking and a combination of the two. When infrared baking is employed, either alone or in combination with microwave baking, the bread tow must be in a twisted form to 30 maintain the desired porous structure during dough baking and to enable splintering of the baked tow to be effected.
Twisting of the dough prior to baking may be effected on a continuous tow, if such is formed in the 35 continuous process discussed above. Alternatively, where the batch process is used, the stretched pieces are twisted together in pairs or greater numbers. The number of twists effected depends, to some extent, on the length of the individual tow pieces, and usually is about 4 to about 10 times. Such twisting preferably is effected after initial stretching, although the process is effective if the twisting is carried out prior to stretching.
Where microwave baking alone is used, the baking may be effected on a continuous stretched tow without twisting and hence is preferred.
When the baking is effected wholly in an infra-red baking oven, the oven temperature may vary from about 325 to about 400F to result in an internal temperature of baked dough of about 175 to about 210F.
The bake time required is usually about 25 to about 40 minutes.
When the baking is effected by a combination of microwave baking followed by infrared baking, the microwave baking operation is effected at a microwave energy input of about 1.0 to about 2.0 KWH/100 lb of dough for a time sufficient to result in an internal temperature of about 125 to about 175F, usually about 60 to about 180 seconds. During the microwave baking, an aix flow is maintained to remove moisture evaporated in the baking process. Dough passes through the microwave oven at a throughput rate of about 50 to about 200 lb of dough per hour.
Following completion of the microwave baking step, the partially-baked dough is subjected to infra-red oven baking to complete the baking step. The oven baking may be effected at a temperature in the range of about 325F to about 400F for a time sufficient to result in a 30 dough temperature of about 175 to about 210F, preferably about 190F, generally in about 10 to about 25 minutes.
In effecting wholly microwave baking on stretched dough, the conveyor belt of the oven is xun faster than the rate of feed of the tow, so as to maintain the tension in the elongate direction of the tow and thereby maintain the elongation of the pores during gas expansion induced by the baking. The differential in speed is such that the conveyor belt of the microwave --oven moves at about 5 to about 20~ faster than the feed rate.
Preferably, when this procedure is adopted, chemical leavening agents are used in the dough-forming components, such chemical leavening agents being chosen to have residual leavening activity during the microwave baking operation, so as to counteract the compression applied to the pores by the stretching step.
The microwave energy input is about 1.7 to about 3.7 KWH/100 lb of dough for a time to result in an internal temperature of preferably about 175F to about 210F, usually in about 10 to about 300 seconds. The microwave initially sets the structure of the stretched tow and then bakes the dough to a fully baked state.
During the microwave baking, an air flow is maintained to remove moisture evaporated in the baking process. Moisture loss during the microwave baking varies rom about 3% to about 12% by weight. Such moisture removal is neces~ary in order to reach the desired internal temperature of the fully cooked product.
Following completion of the baking of the dough, the loaves are allowed to stand for a period of time to permit the loaves to cool. The cooling may be effected, for microwave-baked loaves, for about 6 minutes 25 to about 4 hours and for oven-baked loaves, for about 1 to about 24 hours, usually by standing on perforated racks.
As the tow emerges baked from the oven, it lacks the mechanical strength to be shredded or ground 30 without compaction. ~he short cooling period permits the bread to become more rigid and hence able to undergo shredding or grinding.
The cooling period which is used in the preferred embodiment of the invention contrasts markedly 35 with the procedure required when the conventional procedure is used, in that the prior art requires a long staling period, typically about 18 hours, before the bread becomes rigid enough for grinding. In contrast, the rapid process used in this invention does not give t 16~3~5 rise to the formation of antistaling components and hence the baked dough rapidly achieves a staled condition sufficient to permit shredding to a spllnter shape only a short time after completion of baking.
The cooled loaves next are ground to cause comminution of the loaves and formation of Oriental-style breading crumbs. The dried breading crumbs formed in this way have an elongate splinter shape, characteristic of Oriental-style breading crumbs. The crumbs are dried to a moisture level below about 12 wt.~, preferably about 3 to about 7 wt.%.
The properties of the product which results from the process of the invention may approximate those of the product produced by the conventional process.
15 However, by varying the ingredients and processing conditions, the crumbs may have less fragility and a significantly improved shelf life when compared with the prior art, and may have a variable browning rate and/or a variable texture.
The invention is il~ustrated by the following Examples:
Example 1 This Example illustrates the preparation of Oriental-style breading crumbs wherein baking is effected using partially microwave baking and partially infrared baking.
Two separate compositions were prepared, namely a dry mix and a liquid brew. The compositions had the following constituents:

The dry mix, liquid brew and additional water were fed to one end of an extruder at the following feed rates:
Dry mix 15 lb/min Liquid brew 10.3 lb/min Water 2.5 lb/min which corresponds to an inlet moisture content of 45% by weight.
The components were continuously intermixed during passage ~rom one end of the extruder to the other over a period of about 35 `seconds. Carbon dioxide was fed into the extruder at six different locations along the length of the extruder at a rate of 3.4 SCF/100 lb 20 dough while the extruder was heated to result in a dough having a temperature of 110F at the exit of the extruder. Work was applied to the dough during formation thereof and passage through the extrud~r of 10 watt hr/lb of dough and a back pressure of 110 psig existed at the 25 extruder outlet orifice.
A continuous dough tow of about 3 inches in diameter was extruded from the extruder and cut into 9 inch length loaves (about 1 lb). These loaves were stretched to about 5 times their original length. Two 30 pieces were placed side by side, twisted together about 7 times and then baked. The baking was effected using a successive combination of microwave and infrared heating.
The microwave baking was effected to set the dough and maintain the desired pore structure at an 35 energy input of 1.6 KWH/100 lb dough while a flow of air at a temperature of about 250F was passed through the oven to remove the moisture. The microwave baking was effected to result in an internal temperature of the dough of 150F.
The infrared baking of the microwave-baked dough was effected at an oven temperature of about 350F
for 15 minutes to result in an internal temperature of the baked dough of 190F.
The loaves were then cooled for about 60 minutes, ground to the desired particle size and dried to a moisture content of about 5% by weight. The resulting crumbs had the characteristic shape of the Oriental-style breading crumb and had the following properties:

A continuous dough tow of about 3 inches in diameter was extruded and conveyed along a cloth belt in
2 minutes to a stretching apparatus comprising a plurality of continuous conveyor belts which move at successively increasing speeds. The continuous tow was stretched to about 5.5 times its original length on the stretching conveyors over a period of about 3 minutes and then was passed into a tunnel microwave oven through which the stretched tow was conveyed on a belt.
The belt of the oven moved at a speed about 10%
30 faster than that of the last conveyor of the stretching apparatus to maintain the elongated structure of the pores in the dough. The dough was baked in the microwave oven at an energy input of 2.7 KWH/100 lb of dough while an air flow was passed through the oven to remove 35 moisture.
