Abstract
The present invention relates to a liquid, shelf stable ready to use baker's wash for coating bakery products such as rolls, breads and pie crusts. The wash can be applied either before or after baking to provide a shine to the bakery product. The composition is packaged in an anaerobic environment, such as an aerosol spray. The product provides a convenient way of dispensing the product in use, while maintaining the antimicrobial stability of the product over its useful life. This result is achieved using a preservative composition which contains a mixture of methylparaben and propylparaben, wherein the ratio by weight of the materials is at least about 1.25:1. The composition comprises at least one no-egg white protein, such as caseinate, at least one anti-precipitive agent, at least one viscosity control stabilizer, the preservative composition described above, and water.

egg white baker's wash is disclosed in U.S. Patent 4,115,592, Eergquist, et at., issued September 19, I97$. T'hc Bergquist, et al. patent discloses a process for preparing dried egg white having improved flow and water solubility x5 characteristics. T6e process produces a powder comprised primarily of drial egg white and sugar. lNhen it is desires! to use the powdered composition on bakery gadds, the powder is dissolved itt water and applied by spraying, brushing or the liYe.
30 F.,gB white washes, like that of Eergquis<, at aL, are not shelf stable.
Once the egg white powder is dissolved in the water, it has to be used within abort 8 hours. ~ After ono day, the microorganism growth.in the composition becomes prohibitively high such that the wash can no longer be employed on bakery goads. For this reason, it is necessary to make a Fre~h wa3ir suixture 35 every clay. Since the liquid wash is a good medium fox microorganism growth, manufacturers of egg white washes supplied bakeries with the product in a powder form which has a longer shelf life. However, contamination of the dry egg white powder often occurs since the powder is capable of supporting microorganism growth, especially in humid conditions, the egg white powder being very hydrophilic. Making a wash composition with contaminated egg white powder accelerates microorganism growth so that the wash quickly becomes unusable or, at best, the application lifetime of the wash is greatly reduced.
In response to widespread abuses by bakeries, health departments of various states outlawed baker's washes which employed egg white. Southern states having warm moist climates, such as Louisiana, have been particularly concerned with microorganism growth on food products. As a result, the southern states were generally the first ones to outlaw the use of baker's washes having an egg white composition.
In response to these health concerns, manufacturers started developing baker's washes which would produce a shine on bakery products, like the egg white composition wash, but which would not contain egg whites. Primarily, these dry formulations employed a protein substitute for the egg white, such as whey, and included additional ingredients necessary to make the whey perform in a manner similar to egg whites. While these protein compositions function very similarly to the egg white composition washes, they do not serve as a medium for microorganism growth in dry powder form. However, these non-egg white composition washes will support microorganism growth when the wash is in a liquid form. The washes must be used within one day of formulation in order to avoid significant microbiclogical contamination. Consequently, manufacturers produce non-egg white washes in powder form which have a more stable shelf life. Bakeries, then, have to add the powdered product to water to create the wash.

WO 98/46084 _ 3 - PCT/US98/06417 mix the correct proportion of the powder with the right amount of water. For example, in using the non-egg white composition manufactured by the assignee of the present invention, Baker's Bright, Inc., three different proportions of powder are employed based upon different applications. The before oven application for bread or rolls requires 3.25 ounces of the powder composition to be mixed with one quart of warm water (120°-130°F), the after oven application for bread or rolls requires 2.5 - 3.25 ounces of the powder composition to be mixed with one quart of warm water. The before oven application for pies requires that 4 ounces of the powdered composition be mixed with one quart of warm water and, optionally, 2 ounces of vegetable oil. These different proportions and preparations of the powder sometimes confuse the baker, resulting in incorrectly formulated wash products and ultimately, bakery products which are less appealing to the consumer. The result is that dry powders are more useful in commercial baking where production formulation controls maintain wash uniformity.
Further, once the composition has been mixed with the warm water, it must set for about one-half hour in order to fully dissolve, obtain a uniform viscosity, and become homogeneous. Failure to permit the wash to set for the full time may result in a partially undissolved product having a lumpy composition which cannot be sprayed and which gives an undesirable appearance, even if brushed on the bakery product, because little or no shine is produced.
There was, therefore, a need for a baker's wash which does not contain any egg white, is ready to use in liquid form, and is shelf stable. By shelf stable, it is meant that the wash is capable of lasting at least 21 days after opening, with proper refrigeration. In effect, a shelf stable baker's wash must meet the minimum microorganism standards required by the FDA, both before and after opening. Once the microorganism level exceeds the minimum FDA
requirements, the wash is no longer said to.be shelf stable. These problems were effectively addressed by U.S. Patent 4,863,751, Voss, issued i..4\. W w!-.i ~ ,n n...~.W ..v m.~ ~ . .. _ . , ~ , . ,~ .

These compositions are exempli;ied as being useful in aaditionai aerobic packaging for bakery operations. The compositions are easy tc apply and provide a desirable sheen to the finished baked product. The compositions are resistant to the growth of gram positive and gram negasve bacteria, as well as yeast and mold. The composition utilises a unique preservative system which comprises a mixture of methylparaben and propylparaben together with a suitable dispersing agent, such as a,giycol.
In spite of the success, both technologically and commerciahy, of th~c product described in the Voss patent, there is a continuing desire to formulate baker's w~as6 products in an anaerobic-type environment, such as in as aerosol spray. Such products would be very easy to dispense and use. Howev er, packaging the vc~ash composition in an anaerobic, rather than an aerobic, environment makes the composition vulnerable to different types of microorganisms, facultative anaerobic m.icroorganistns, such as gram negative facultative anaerobic rods (Enterobacteriaceae, including Escherichia, Enterobacter and Salmonella), gram positive facultative anaerobic cocci (Mieroccxcaceae, including Staphylococcus, Enteroeoe.~.us and l:actrcoccusj and gram positive facultative anaerobic nonsporulating regular rods (Lactobacillus).
Since a_~aerobic microorganisms function physiologically in an ent;rely different manner frorr~ aerobic miczoorganisms, many preservative systems which are effective in an aerobic environment are not effective in an anaerobic context, particularly in the neutral pH range. Other preservatives, such as sodxulxl benzoate, sorbates, propionates, sulfites and parabens are used In acidified or alcohol-based products to control microorganisms under aerobic, facultative and anaerobic conditions., However, none of these preservatives are known to function in the neutral product pH range.

SUMMARY OF THE INVENTION
S
The above-described objectives are achieved with the wash of the present invention which contains no egg products, is shelf stable when packaged in an anaerobic environment, remains shelf stable after opening, with refrigeration, and is ready to use after agitating the contents of the wash.
The present invention is anaerobically packaged (such as in an aerosol spray) and comprises a ready to use, shelf stable aqueous wash for providing a shine on bakery products. The composition broadly contains from about 4.9% to about 9 % of at least one non-egg white protein, at least one anti-precipitive agent if required by the particular protein used, at least one viscosity control stabilizer, and a neutral pH effective preservative composition. The preservative composition comprises a mixture of methylparaben and propylparaben together with a suitable dispersing agent, such as a glycol.
DETAILED DESCRIPTION OF THE INVENTION
A coating is described for providing a shine on bakery products such as breads, rolls, pie crusts and the like, which is ready to use, contains no egg products, is shelf stable, and also acts as a moisture barrier. The ready to use coating compositions generally comprise from about 4.9 % to about 9 % non-egg white protein, a specifically-defined neutral pH effective preservative system, an anti-precipitive agent if required by the particular protein used, and a viscosity control stabilizer in an aqueous mixture.
These compositions are packaged and stored in an anaerobic environment using conventional packaging techniques {i.e., in an anaerobic package environment). As used herein "anaerobic environment" recognizes the fact that low levels of oxygen may be present in the product as a result of the packing process (i.e., a facultative anaerobic environment). Thus, "anaerobic environment" includes products which include up to about 3 % , preferably up to about 2 % , residual oxygen. Examples of such aerosol general anaerobic environments include aerosol sprays using non-foaming nitrogen gas propellant;
other propellant blends, such as propane and isobutane and other blends of required hydrostatic pressure ratios, which typically cause foaming during dispensing; or a bag-in-can dispensing system. In the latter, a plastic or multilayered polyester/aluminum foil bag, attached can closure and spraying IO device, is sealed into the propellent pressurized aerosol container. The composition is injected into the bag, under pressure, through the mechanism of the spraying device. Rather than adding the propellant directly to the composition, as would be done in an aerosol spray, the propellant is in the container that surrounds the bag containing the composition to be sprayed.
IS Aerosol sprays which may be used in the present invention are welt-known in the art. Examples of propellants which may be used are discussed above. Nitrogen tends to be a preferred propellant since it minimizes foaming of the composition.
The compositions of the present invention should have pH of at least 20 about 5, preferably from about 5 to about 8, and are more preferably are neutral in pH, having a pH of from about 6 to about 7, most preferably about 7.
The non-egg white protein source of the present invention may contain from about 60 % to about 95 % protein and may include ingredients of varying 25 protein content such as sodium, calcium or sodium/calcium caseinates, soy proteins (concentrates and isolates), whey proteins, yeast proteins, and mixtures thereof. Any protein concentrate, including corn zein, wheat, rice and other vegetablelgrain proteins, as well as animal blood proteins, may be used in the present invention. Preferably, the non-egg white protein source is granular or 30 powdered sodium and/or calcium caseinate which usually has a protein content of from about 80 % to about 92 % , or whey protein concentrate usually having a protein content of about 75% to about 90%. Sodium caseinate is particularly - 'j preferred. The proportion of protein in the protein source is not critical.
However, the final ready to use baker's shine composition should have at least about 4. 9 % (and preferably from about 4. 9 % to about 9. 0 % ) protein in order to produce acceptable shine characteristics. Preferred compositions contain from about 6.2 % to about 7.0 %, most preferably about 6.6 % , of the protein. The amount of the selected protein source can be adjusted to assure at least such a protein level.
Because caseinates are the preferred protein source, since they are high in protein content, it is contemplated that they will be frequently used as an egg white substitute protein source in formulating the present invention. To prevent coagulation or aggregation of the protein, an anti-precipitive agent is employed.
This not only prevents any caseinates from curdling, but also makes the protein from any protein sources more soluble and prevents aggregation and coagulation of the denatured proteins.
The anti-precipitive agents which may be used in the present invention include any of those which are compatible with the protein and the other components utilized in the present composition and which are also suitable for human ingestion. The preferred anti-precipitive agents are those selected from the group consisting of phosphates and polyphosphates, preferably sodium hexametaphosphate, which may be used at a level of from about 0.04 % to about 0.12 % by weight of the composition. Although phosphates generally may be used as an anti-precipitive agent, disodium phosphates and phosphates or polyphosphates containing calcium should be avoided as they sometimes tend to create precipitation problems. Anti-precipitive agents may also include viscosity control ingredients which maintain physical protein molecule separation. Salt may also be used as an anti-precipitive agent, but at a higher level than defined above.
Viscosity control stabilizers which may be used in the present invention include those which are compatible with the other components contained in the WO 98/46084 _ 8 - PCT/US98/06417 baker's wash compositions and which are suitable for human ingestion. These may include carrageenan, tragacanth gum, xanthan gum, arabic gum, guar gum, carboxymethylcellulose, gelatin, corn syrup solids, maltodextrins, and mixtures thereof. The preferred viscosity control stabilizer is carrageenan, such as Viscarin SD389, commercially available from Marine Colloids Division of FMC
Corporation. The amount of viscosity control stabilizer used in the present invention will vary depending upon the desired thickness of the resulting baker's shine composition. The thickness of the composition should be sufficient to maintain the baker's shine composition on the bakery product, but should not be so great as to make the composition difficult to dispense by spraying. The precise amount of viscosity control stabilizer to be included in the composition will largely be determined by the nature of the particular stabilizer being used and the determination of such a suitable level is well within the knowledge of one skilled in the art. It is preferred that the viscosity control stabilizer comprise at least about 0.05 % , and preferably from about 0.05 % to about 0.30 % , by weight of the composition. The precise levels used will depend on the particular ingredients included in the composition.
The preservative system utilized in the present invention comprises generally a mixture of methyl- and propylparabens and at least one glycol or other suitable dispersing agent. Preferably, propylene glycol is employed as a dispersing agent because it also aids in inhibiting both fermentation and mold growth. Other glycols, polysorbates and the like can be employed as the dispersing agent component. The combination of the parabens in the present invention is preferred because it has been found that neither paraben by itself is satisfactory in preventing microorganism growth. Parabens, independently effective in yeast and mold growth at a neutral pH, but are of limited effectiveness against gram negative bacteria. Together, the two parabens control gram negative bacteria, as well as a broad spectrum of facultative anaerobic microorganisms.
The preservative system of the present invention contains methylparaben -S
and propylparaben in amounts such that the relative ratios of the two parabens are at least about 1.25:1, and preferably are in the range of from about 1.25 :1 to about 4:1 (methylparaben:propylparaben). The amount of methylparaben in the baker's wash composition is preferably in the range of from about 0.25 % by weight to about 0.4% by weight, preferably about 0.4% by weight (based on the total weight of the baker's wash composition). The amount of propylparaben is then selected, based on the amount of methylparaben, so that the mixture falls within the above-described ratio ranges. The amount of propylparaben, therefore, preferably contained is from about 0.1 % to about 0.3 % , preferably about 0.1 % of the baker's wash compositions. The preferable ratio of methylparaben to propylparaben in the composition of the present invention is about 4:1. The combined- amount of methylparaben and propylparaben contained in the compositions should be at least about 0.45 % .
A dispersing agent is necessary because both parabens are only slightly soluble in water, but are very soluble in glycols, such as propylene glycol, and in polysorbates. The glycols and polysorhates, on the other hand, are very soluble in water. Thus, each component in the neutral pH preservative system performs a necessary task. The dispersing agent used in the present invention need only be present in an amount sufficient to properly effect mixing of the parabens and allow incorporation of the mixture into a food product, i.e., the baker's wash product, although a greater amount may also be used. The preferred preservative composition (i.e., dispersing agent, methylparaben and propylparaben) contains about 80% propylene glycol, about 16% methylparaben and about 4%
propylparaben, and is preferably present in the baker's wash composition at a level of at least about 2.25 % , preferably about 2.5 % by weight.
The baker's wash composition may optionally include one or more coloring agents, pH buffers, or antioxidants which are well known in the art, are commercially available, and would be used at their art-established levels.
The optional coloring agent is preferably selected from the group -lU_ consisting of caramel, tumeric or, more preferably, carotene, or other artificial or natural yellow "egg" coloring agents. The optional antioxidants may, for example, be selected from BHA, BHT, TBHQ, propyl gallate with citric acid, tocopherols, or the like. Suitable pH buffers, for example, are selected from any of those known in the art which are suitable for use in an edible food composition. The composition may also include aroma enhancers or modifiers (suitable for use in edible products), if desired, to provide the composition with a consumer-preferred aroma when sprayed.
Depending upon the use of the baker's wash composition, suitable vegetable oils, such as, for example, soy bean oil may be incorporated into the composition to improve the shine characteristics and maintain moisture within the bakery product. This would be particularly useful where the baker's wash product is used on a pie crust.
The water used in the present invention may be ordinary tap water having a pH of from about 6 to about 7. Any type of pure treated water can be employed so long as it meets federal clean water standards.
Occasionally, when formulated as a spray, particularly an aerosol spray, the baker's wash composition can become dried out at the nozzle exit, thereby clogging the nozzle and preventing further spray. In some formulations this may happen over time at room temperature, but the condition may be accelerated at elevated bakery temperatures. Further, while smaller nozzle openings (e.g., 13 mm) are frequently preferred for dispensing the baker's wash composition, these smaller openings may also be more prone to clogging than larger (e.g., 16 or mm) openings.
In any event, this clogging can be eliminated by adding low levels of surfactants (food grade), particularly nonionic surfactants to the composition.
Particularly preferred are surfactants which 'additionally act as lubricants and emulsifiers. Examples of such materials include silicone surfactants, alkylene WO 98/46084 PCT/US98/Ob417 -11_ glycols (e.g., propylene glycol); phospholipids (e.g., lecithin), and polysorbate materials. These materials are generally included at levels ranging from about 0.01% to about 5% of the finished composition. Some of these materials (e.g., propylene glycols) are also useful as dispersants for the preservative system, as previously described. When they are used as anti-clogging agents, they are included in the composition at higher levels and serve both functions. These materials are usefully combined with each other and may also be combined with edible oils, such as canola oil, to form effective anti-clog agents. In formulating these anti-clog agents, it is important to test them to make sure they do not adversely affect the shine provided by the finished composition on the baked goods. Examples of anti-clog agents useful in the baker's wash compositions of the present invention include (percentages are of the finished baker's wash composition):
A. Canola Oil (1.0% ) + Polysorbate 60 (0.025 % ) + Polysorbate 80 (0.012 %) B. Canola Oil (1.0%) + Polysorbate 60 (0,025%) + Polysorbate 80 (0.012 % ) + Lecithin (0.5 % ) C.

However, these non-egg white composition washes will support microorganism growth when the wash is in a liquid form. The washes must be used within one day of formulation in order to avoid significant microbiclogical contamination. Consequently, manufacturers produce non-egg white washes in powder form which have a more stable shelf life. Bakeries, then, have to add the powdered product to water to create the wash.

WO 98/46084 _ 3 - PCT/US98/06417 mix the correct proportion of the powder with the right amount of water. For example, in using the non-egg white composition manufactured by the assignee of the present invention, Baker's Bright, Inc., three different proportions of powder are employed based upon different applications. The before oven application for bread or rolls requires 3.25 ounces of the powder composition to be mixed with one quart of warm water (120°-130°F), the after oven application for bread or rolls requires 2.5 - 3.25 ounces of the powder composition to be mixed with one quart of warm water. The before oven application for pies requires that 4 ounces of the powdered composition be mixed with one quart of warm water and, optionally, 2 ounces of vegetable oil. These different proportions and preparations of the powder sometimes confuse the baker, resulting in incorrectly formulated wash products and ultimately, bakery products which are less appealing to the consumer. The result is that dry powders are more useful in commercial baking where production formulation controls maintain wash uniformity.
Further, once the composition has been mixed with the warm water, it must set for about one-half hour in order to fully dissolve, obtain a uniform viscosity, and become homogeneous. Failure to permit the wash to set for the full time may result in a partially undissolved product having a lumpy composition which cannot be sprayed and which gives an undesirable appearance, even if brushed on the bakery product, because little or no shine is produced.
There was, therefore, a need for a baker's wash which does not contain any egg white, is ready to use in liquid form, and is shelf stable. By shelf stable, it is meant that the wash is capable of lasting at least 21 days after opening, with proper refrigeration. In effect, a shelf stable baker's wash must meet the minimum microorganism standards required by the FDA, both before and after opening. Once the microorganism level exceeds the minimum FDA
requirements, the wash is no longer said to.be shelf stable. These problems were effectively addressed by U.S. Patent 4,863,751, Voss, issued i..4\. W w!-.i ~ ,n n...~.W ..v m.~ ~ . .. _ . , ~ , . ,~ .

These compositions are exempli;ied as being useful in aaditionai aerobic packaging for bakery operations. The compositions are easy tc apply and provide a desirable sheen to the finished baked product. The compositions are resistant to the growth of gram positive and gram negasve bacteria, as well as yeast and mold. The composition utilises a unique preservative system which comprises a mixture of methylparaben and propylparaben together with a suitable dispersing agent, such as a,giycol.
In spite of the success, both technologically and commerciahy, of th~c product described in the Voss patent, there is a continuing desire to formulate baker's w~as6 products in an anaerobic-type environment, such as in as aerosol spray. Such products would be very easy to dispense and use. Howev er, packaging the vc~ash composition in an anaerobic, rather than an aerobic, environment makes the composition vulnerable to different types of microorganisms, facultative anaerobic m.icroorganistns, such as gram negative facultative anaerobic rods (Enterobacteriaceae, including Escherichia, Enterobacter and Salmonella), gram positive facultative anaerobic cocci (Mieroccxcaceae, including Staphylococcus, Enteroeoe.~.us and l:actrcoccusj and gram positive facultative anaerobic nonsporulating regular rods (Lactobacillus).

SUMMARY OF THE INVENTION
S
The above-described objectives are achieved with the wash of the present invention which contains no egg products, is shelf stable when packaged in an anaerobic environment, remains shelf stable after opening, with refrigeration, and is ready to use after agitating the contents of the wash.
The present invention is anaerobically packaged (such as in an aerosol spray) and comprises a ready to use, shelf stable aqueous wash for providing a shine on bakery products. The composition broadly contains from about 4.9% to about 9 % of at least one non-egg white protein, at least one anti-precipitive agent if required by the particular protein used, at least one viscosity control stabilizer, and a neutral pH effective preservative composition. The preservative composition comprises a mixture of methylparaben and propylparaben together with a suitable dispersing agent, such as a glycol.
DETAILED DESCRIPTION OF THE INVENTION
A coating is described for providing a shine on bakery products such as breads, rolls, pie crusts and the like, which is ready to use, contains no egg products, is shelf stable, and also acts as a moisture barrier. The ready to use coating compositions generally comprise from about 4.9 % to about 9 % non-egg white protein, a specifically-defined neutral pH effective preservative system, an anti-precipitive agent if required by the particular protein used, and a viscosity control stabilizer in an aqueous mixture.
These compositions are packaged and stored in an anaerobic environment using conventional packaging techniques {i.e., in an anaerobic package environment). As used herein "anaerobic environment" recognizes the fact that low levels of oxygen may be present in the product as a result of the packing process (i.e., a facultative anaerobic environment). Thus, "anaerobic environment" includes products which include up to about 3 % , preferably up to about 2 % , residual oxygen. Examples of such aerosol general anaerobic environments include aerosol sprays using non-foaming nitrogen gas propellant;
other propellant blends, such as propane and isobutane and other blends of required hydrostatic pressure ratios, which typically cause foaming during dispensing; or a bag-in-can dispensing system. In the latter, a plastic or multilayered polyester/aluminum foil bag, attached can closure and spraying IO device, is sealed into the propellent pressurized aerosol container. The composition is injected into the bag, under pressure, through the mechanism of the spraying device. Rather than adding the propellant directly to the composition, as would be done in an aerosol spray, the propellant is in the container that surrounds the bag containing the composition to be sprayed.
IS Aerosol sprays which may be used in the present invention are welt-known in the art. Examples of propellants which may be used are discussed above. Nitrogen tends to be a preferred propellant since it minimizes foaming of the composition.
The compositions of the present invention should have pH of at least 20 about 5, preferably from about 5 to about 8, and are more preferably are neutral in pH, having a pH of from about 6 to about 7, most preferably about 7.
The non-egg white protein source of the present invention may contain from about 60 % to about 95 % protein and may include ingredients of varying 25 protein content such as sodium, calcium or sodium/calcium caseinates, soy proteins (concentrates and isolates), whey proteins, yeast proteins, and mixtures thereof. Any protein concentrate, including corn zein, wheat, rice and other vegetablelgrain proteins, as well as animal blood proteins, may be used in the present invention. Preferably, the non-egg white protein source is granular or 30 powdered sodium and/or calcium caseinate which usually has a protein content of from about 80 % to about 92 % , or whey protein concentrate usually having a protein content of about 75% to about 90%. Sodium caseinate is particularly - 'j preferred. The proportion of protein in the protein source is not critical.
However, the final ready to use baker's shine composition should have at least about 4. 9 % (and preferably from about 4. 9 % to about 9. 0 % ) protein in order to produce acceptable shine characteristics. Preferred compositions contain from about 6.2 % to about 7.0 %, most preferably about 6.6 % , of the protein. The amount of the selected protein source can be adjusted to assure at least such a protein level.
Because caseinates are the preferred protein source, since they are high in protein content, it is contemplated that they will be frequently used as an egg white substitute protein source in formulating the present invention. To prevent coagulation or aggregation of the protein, an anti-precipitive agent is employed.
This not only prevents any caseinates from curdling, but also makes the protein from any protein sources more soluble and prevents aggregation and coagulation of the denatured proteins.
The anti-precipitive agents which may be used in the present invention include any of those which are compatible with the protein and the other components utilized in the present composition and which are also suitable for human ingestion. The preferred anti-precipitive agents are those selected from the group consisting of phosphates and polyphosphates, preferably sodium hexametaphosphate, which may be used at a level of from about 0.04 % to about 0.12 % by weight of the composition. Although phosphates generally may be used as an anti-precipitive agent, disodium phosphates and phosphates or polyphosphates containing calcium should be avoided as they sometimes tend to create precipitation problems. Anti-precipitive agents may also include viscosity control ingredients which maintain physical protein molecule separation. Salt may also be used as an anti-precipitive agent, but at a higher level than defined above.
Viscosity control stabilizers which may be used in the present invention include those which are compatible with the other components contained in the WO 98/46084 _ 8 - PCT/US98/06417 baker's wash compositions and which are suitable for human ingestion. These may include carrageenan, tragacanth gum, xanthan gum, arabic gum, guar gum, carboxymethylcellulose, gelatin, corn syrup solids, maltodextrins, and mixtures thereof. The preferred viscosity control stabilizer is carrageenan, such as Viscarin SD389, commercially available from Marine Colloids Division of FMC
Corporation. The amount of viscosity control stabilizer used in the present invention will vary depending upon the desired thickness of the resulting baker's shine composition. The thickness of the composition should be sufficient to maintain the baker's shine composition on the bakery product, but should not be so great as to make the composition difficult to dispense by spraying. The precise amount of viscosity control stabilizer to be included in the composition will largely be determined by the nature of the particular stabilizer being used and the determination of such a suitable level is well within the knowledge of one skilled in the art. It is preferred that the viscosity control stabilizer comprise at least about 0.05 % , and preferably from about 0.05 % to about 0.30 % , by weight of the composition. The precise levels used will depend on the particular ingredients included in the composition.
The preservative system utilized in the present invention comprises generally a mixture of methyl- and propylparabens and at least one glycol or other suitable dispersing agent. Preferably, propylene glycol is employed as a dispersing agent because it also aids in inhibiting both fermentation and mold growth. Other glycols, polysorbates and the like can be employed as the dispersing agent component. The combination of the parabens in the present invention is preferred because it has been found that neither paraben by itself is satisfactory in preventing microorganism growth. Parabens, independently effective in yeast and mold growth at a neutral pH, but are of limited effectiveness against gram negative bacteria. Together, the two parabens control gram negative bacteria, as well as a broad spectrum of facultative anaerobic microorganisms.
The preservative system of the present invention contains methylparaben -S
and propylparaben in amounts such that the relative ratios of the two parabens are at least about 1.25:1, and preferably are in the range of from about 1.25 :1 to about 4:1 (methylparaben:propylparaben). The amount of methylparaben in the baker's wash composition is preferably in the range of from about 0.25 % by weight to about 0.4% by weight, preferably about 0.4% by weight (based on the total weight of the baker's wash composition). The amount of propylparaben is then selected, based on the amount of methylparaben, so that the mixture falls within the above-described ratio ranges. The amount of propylparaben, therefore, preferably contained is from about 0.1 % to about 0.3 % , preferably about 0.1 % of the baker's wash compositions. The preferable ratio of methylparaben to propylparaben in the composition of the present invention is about 4:1. The combined- amount of methylparaben and propylparaben contained in the compositions should be at least about 0.45 % .
A dispersing agent is necessary because both parabens are only slightly soluble in water, but are very soluble in glycols, such as propylene glycol, and in polysorbates. The glycols and polysorhates, on the other hand, are very soluble in water. Thus, each component in the neutral pH preservative system performs a necessary task. The dispersing agent used in the present invention need only be present in an amount sufficient to properly effect mixing of the parabens and allow incorporation of the mixture into a food product, i.e., the baker's wash product, although a greater amount may also be used. The preferred preservative composition (i.e., dispersing agent, methylparaben and propylparaben) contains about 80% propylene glycol, about 16% methylparaben and about 4%
propylparaben, and is preferably present in the baker's wash composition at a level of at least about 2.25 % , preferably about 2.5 % by weight.
The baker's wash composition may optionally include one or more coloring agents, pH buffers, or antioxidants which are well known in the art, are commercially available, and would be used at their art-established levels.
The optional coloring agent is preferably selected from the group -lU_ consisting of caramel, tumeric or, more preferably, carotene, or other artificial or natural yellow "egg" coloring agents. The optional antioxidants may, for example, be selected from BHA, BHT, TBHQ, propyl gallate with citric acid, tocopherols, or the like. Suitable pH buffers, for example, are selected from any of those known in the art which are suitable for use in an edible food composition. The composition may also include aroma enhancers or modifiers (suitable for use in edible products), if desired, to provide the composition with a consumer-preferred aroma when sprayed.
Depending upon the use of the baker's wash composition, suitable vegetable oils, such as, for example, soy bean oil may be incorporated into the composition to improve the shine characteristics and maintain moisture within the bakery product. This would be particularly useful where the baker's wash product is used on a pie crust.
The water used in the present invention may be ordinary tap water having a pH of from about 6 to about 7. Any type of pure treated water can be employed so long as it meets federal clean water standards.
Occasionally, when formulated as a spray, particularly an aerosol spray, the baker's wash composition can become dried out at the nozzle exit, thereby clogging the nozzle and preventing further spray. In some formulations this may happen over time at room temperature, but the condition may be accelerated at elevated bakery temperatures. Further, while smaller nozzle openings (e.g., 13 mm) are frequently preferred for dispensing the baker's wash composition, these smaller openings may also be more prone to clogging than larger (e.g., 16 or mm) openings.
In any event, this clogging can be eliminated by adding low levels of surfactants (food grade), particularly nonionic surfactants to the composition.
Particularly preferred are surfactants which 'additionally act as lubricants and emulsifiers. Examples of such materials include silicone surfactants, alkylene WO 98/46084 PCT/US98/Ob417 -11_ glycols (e.g., propylene glycol); phospholipids (e.g., lecithin), and polysorbate materials. These materials are generally included at levels ranging from about 0.01% to about 5% of the finished composition. Some of these materials (e.g., propylene glycols) are also useful as dispersants for the preservative system, as previously described. When they are used as anti-clogging agents, they are included in the composition at higher levels and serve both functions. These materials are usefully combined with each other and may also be combined with edible oils, such as canola oil, to form effective anti-clog agents. In formulating these anti-clog agents, it is important to test them to make sure they do not adversely affect the shine provided by the finished composition on the baked goods. Examples of anti-clog agents useful in the baker's wash compositions of the present invention include (percentages are of the finished baker's wash composition):
A. Canola Oil (1.0% ) + Polysorbate 60 (0.025 % ) + Polysorbate 80 (0.012 %) B. Canola Oil (1.0%) + Polysorbate 60 (0,025%) + Polysorbate 80 (0.012 % ) + Lecithin (0.5 % ) C.
