DESCRIPTION
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. Provisional Application Ser. No. 61/523,686, filed Aug. 15, 2011.
BACKGROUND
Baked good microbial spoilage and the corresponding loss of saleable product is a major issue facing the baking industry, causing millions of dollars in product losses per year. Due to advancements in enzyme technology in recent years, fresh keeping qualities (softness, reduction in staleness) of baked goods have increased the saleable shelf life of these baked goods from a period of days to weeks. Microbial spoilage has now become the limiting factor as to how long a baked good can remain edible.
During the baking process high heat environment, baked goods are essentially free from any microbial contamination; however, once the baked good exits the oven and starts to cool, the main source of microbial contamination comes from air-born mold spores and through contact with contaminated production equipment, (conveyors and slicers). Baked products have a relatively fast microbial spoilage rate, specifically due to mold spoilage because of the types of ingredients used, the relatively high water activity of the finished product (>0.90 Aw), and the average finished product having a pH of between 5-6.
For “yeast raised” baked goods the baking industry traditionally relies on microbial preservatives that are based on an organic acid, propionic acid, and its related salt compounds. These propionic acid based anti-microbial compounds can be both chemically and naturally derived. The chemically derived anti-microbials frequently used by the baking industry are calcium propionate and sodium propionate. Naturally derived anti-microbial preservatives that contain propionic acid are typically produced by bacterial fermentations of differing substrates such as cultured wheat, cultured wheat starch, cultured corn syrup solids, and/or cultured whey.
Although the use of anti-microbial compounds that are based on propionates as the functional component are effective at slowing down mold growth in baked goods, the consumer and baking industry have been advocating for the development of natural, label friendly preservatives that do not rely on propionic acid or propionate salts as their functional components. There are few natural bread mold inhibitor solutions currently offered in the baking industry that are effective in yeast raised, baked products and that do not rely on propionic acid or its salt version as the functional anti-microbial mold inhibition component. Due to the current customer demand for natural, label friendly ingredients, the baking industry has been attempting to develop a natural mold inhibitor that does not use propionic acid or its salt as its functional component.
Currently, synthetic preservatives such as calcium propionate and natural preservative solutions such as cultured wheat flour/corn syrup (microbially produced propionic acid systems) are used to inhibit mold and to increase bread shelf life in the baking industry. These products currently used all contain propionic acid and/or its salt as the effective anti-microbial component of the system. There are no current effective mold inhibition systems for yeast raised baked products that do not utilize propionic acid or its salt.
Organic acids (vinegar/acetic acid, lactic acid, citric acid) are also used in the baking industry as anti-microbial mold inhibitors. However, when used by themselves, at effective anti-microbial usage levels, the pH of the baked bread is lowered considerably. As a consequence, the low pH of the bread produces an acidic flavor that is not palatable nor desirable.
A secondary consequence of the use of high levels of organic acids to inhibit mold growth in bread is the requirement or usage of high levels of yeast. Yeast levels in formulations are often increased by two to three time due to the inhibitory effect of organic acid on yeast activity.
A tertiary effect of using high organic acid levels in bakery products to inhibit mold growth is the overall negative effect on the rheology of the dough during processing and the consequent lowering of quality in the final end baked product. Excessive organic acid addition to dough systems to inhibit mold growth will cause the protein matrix to weaken, causing processing issues at the bakery as well as with the baked bread. Bread that is baked with dough that is low in pH will typically exhibit lower volumes, open/coarse cell structure, poor overall quality. Because of these occurrences, the baking industry does not use high levels of organic acids as stand-alone preservation systems, but rather, typically uses them only in conjunction with a propionic acid based mold inhibitor to obtain the desired mold free shelf life.
Other organic acids commonly found in the baking industry to retard mold growth include, for example, acetic acid, lactic acid and citric acid. One of ordinary skill in the art will appreciate that these organic acids, when used at functional levels, will have a strong negative effect on the processing, end-baked product quality and palatability of the baked product. First, the amount of the organic acid required to be effective as mold inhibitors will cause the baked product to be unpalatable due to the strong acidic flavor. These attributes lead to diminished consumer acceptance. Second, at the effective mold inhibition usage levels, the organic acids will negatively affect yeast activity, causing excessively long proof times and small baked volumes. Third, the high acidic, low pH environment of the dough system will cause proteins of the dough to break down leading to poor gas retention, inferior crumb structure, poor external symmetry and lower baked volume products. Processing of the dough at the bakeries will also be negatively affected due to the increased stickiness of the dough caused by the weakened proteins.
Examples of other non-propionate based preservatives used in the baking industry include sorbates, benzoates and natamycin; however, these preservatives have disadvantages when used in “yeast raised” bakery applications. First, these agents have strong inhibitory effects on yeast activity when used at effective usage rates. Inhibitory effects on yeast activity will cause excessively long proof times, and small overall baked product volumes. Second, these preservatives will have a negative effect on the dough rheology strength, and as a consequence cause poor overall gas retention in the dough system. This diminished dough strength will lead to small product volume, poor external baked symmetry, and poor internal crumb structure. All of these attributes will lead to diminished consumer acceptance.
Thus, there is an unmet need for compositions and methods for extending the shelf life of bread products which avoid the aforementioned negative effects on processing and baked product quality.

Example 15
Bread is prepared using the no-time, straight dough method by mixing the following ingredients in a Hobart A200 mixer with a McDuffy attachment for a total of 8 minutes until full gluten development is obtained: flour (100%), water (68%), granulated sugar (7%), shortening (4%), fresh yeast (2.5%), 30% acetic acid vinegar or 300 grain vinegar (0%, 2%, 1% or 0.5%), and citric acid (0% or 0.1%). Mixed dough is rested for 10 minutes on bench then scaled into two 520 gram dough pieces and rounded by hand. Rounded dough is rested 10 minutes then is sheeted and molded into logs. Sheeted and molded logs are placed into oiled bread pans and placed into proof box (National Manufacturing) and set to 110° F. and 80% relative humidity. Dough is proofed to a consistent height, as measured by a template which was 0.75 inches above the rim of the bread pan. Proof time is considered to be time for dough to touch the top of the template minus initial time in the proof box. Proofed dough is then placed into an oven and baked for 20 minutes at a temperature of 420° F. Internal temperature of the bread exiting the oven is 195° F.-200° F. Baked bread is cooled at room temperature on a wire rack for one hour to an internal temperature of between 95° F. and 100° F. After cooling, bread is sliced and packaged in plastic bags and sealed with twist ties. Packaged bread is stored at room temperature 70° F.-75° F. and visually inspected for mold appearance on a daily basis. Bread is considered as expired/failed upon first sign of mold.
Results from experiments carried out as above are shown in Table 3. Control bread with no preservatives failed at 8 days. High levels of 300 grain vinegar, 30% acetic acid (2%) had a mold inhibiting effect with the bread failing at 20 days of storage. However, time to proof increased to an unacceptable 119 minutes from a control proof time of 47 minutes. Bread pH of the high level of 300 grain vinegar (2%) was 4.4 as compared to the control bread with no preservatives, which was 5.77. The flavor of the high level of 300 grain vinegar (2%) was considered to be sour and unpalatable to eat. Only when the 300 grain vinegar level was reduced to (0.5%) was the proof time similar to the control (no preservatives) and the bread considered palatable to eat. However, at this usage rate, there was no improvement in mold inhibition as compared to the control without preservatives. Both breads molded at 8 days.

Example 16
Bread is prepared using the no-time, straight dough method by mixing the following ingredients in a Hobart A200 mixer with a McDuffy attachment for a total of 8 minutes until full gluten development was obtained: flour (100%), water (68%), granulated sugar (7%), shortening (4%), fresh yeast (2.5%), with variables being liquid propionic acid free natural mold inhibitor (4%, 3%, 2.5%, 2%, 1%), calcium propionate (0.33%, 0.5%) and a control dough without any preservatives added. Mixed dough is rested for 10 minutes on bench then scaled into two 520 gram dough pieces and rounded by hand. Rounded dough is rested 10 minutes then sheeted and molded into logs. Sheeted and molded logs are placed into oiled bread pans and placed into proof box (National Manufacturing) set to 110° F. and 80% relative humidity. Dough is proofed to a consistent height, as measured by a template which was 0.75 inches above the rim of the bread pan. Proof time is considered to be time for dough to touch the top of the template minus initial time in the proof box. Proofed dough is then placed into an oven and is baked for 20 minutes at a temperature of 420° F. The internal temperature of the bread exiting the oven is 195° F.-200° F. Baked bread is cooled at room temperature on a wire rack for one hour to an internal temperature of between 95° F. and 100° F. After cooling, the bread is sliced and packaged in plastic bags and sealed with twist ties.
Packaged bread is stored at room temperature 70° F.-75° F. Packaged bread is visually inspected for mold appearance on a daily basis. Bread is considered as expired/failed upon first sign of mold. Results are shown in Table 4.

TABLE 5
Data shown in FIG. 1. FIG. 1 illustrates the effects of added
organic acids (non-propionic acid based) on white pan bread mold
inhibition and pH. The data demonstrates that, the use of organic acids
vinegar, citric and lactic acid can be effective as mold inhibitors.
However, when organic acids are used at effective levels to inhibit
mold growth in baked products, the pH of the baked product may be
reduced to a level where the baked good becomes unpalatable. Baked
products that have a pH lower than 5 are considered sour/tart and are
not typical of a standard baked product.

traditional propionate acid based mold inhibitors, calcium propionate
and Nabitor ™ (an anti-microbial product available from AB Mauri)
used in white pan bread. Nabitor ™ is a blend of naturally cultured
corn syrup solids, that contains propionic acid as a byproduct of
fermentation & citric acid. The data illustrates that the Natural Mold
Inhibitors produced with sodium bicarbonate and calcium hydroxide
are as effective in inhibiting the rate of mold growth as compared to
the industry standard propionic acid based mold inhibitors.

TABLE 8
Table 8 illustrates the anti-microbial effects of various levels of dried
propionic acid free natural mold inhibitors (sodium and calcium based mold
inhibitors), compared to calcium propionate and natural cultured,
propionic acid based natural mold inhibitors (Nabitor ™, available from AB
Mauri). Days to mold data illustrates that both the calcium hydroxide and
sodium bicarbonate versions of the dried natural mold inhibitors are effective
as mold inhibitors. As usage levels are increased from 0.33% (flour basis)
to 1.50% (flour basis) there is a corresponding increase in days to mold
found in the bread products. When the dried natural mold inhibitor is used
at 1.50% there was a similar mold inhibiting effect to the use of calcium
propionate used at 0.50% (flour basis) and Nabitor ™ used at 1.00% (flour
basis).
