- Bread improvers have been used in various forms for the past 50-60 years. They typically include yeast nutrients, amylolytic enzymes and oxidising/reducing agents and have a significant role in breadmaking processes through one or both of the following actions: (i) Yeast nutrients and amylolytic enzymes stimulate the rapid production of carbon dioxide from yeast. (ii) An appropriate balance of oxidising and reducing agents provides a rapid modification of the doughs' gluten structure so that optimum gas retention properties are achieved resulting in a good quality loaf being produced.
- Rapid dough processing such as chemical dough development (CDD) and mechanical dough development (MDD), in particular, require the use of bread improvers.
- Present products for this kind of processing contain a balance of oxidising and reducing agents, yeast nutrients, enzymes, soya flour and emulsifier blends.

Description
UQUID BREAD IMPROVER This invention relates to liquid bread improver compositions which may be included in baking mixes, particularly those for bread making.
Bread improvers have been used in various forms for the past 50-60 years. They typically include yeast nutrients, amylolytic enzymes and oxidising/reducing agents and have a significant role in breadmaking processes through one or both of the following actions: (i) Yeast nutrients and amylolytic enzymes stimulate the rapid production of carbon dioxide from yeast. (ii) An appropriate balance of oxidising and reducing agents provides a rapid modification of the doughs' gluten structure so that optimum gas retention properties are achieved resulting in a good quality loaf being produced.
Rapid dough processing such as chemical dough development (CDD) and mechanical dough development (MDD), in particular, require the use of bread improvers. Present products for this kind of processing contain a balance of oxidising and reducing agents, yeast nutrients, enzymes, soya flour and emulsifier blends. These products are manufactured and stored in dry form and include an inert carrier such as flour or starch to eliminate interaction of minor ingredients.
However, whilst these products generally perform well, there is clearly a need for liquid bread improvers because they would be pumpable, readily metered and could be readily dispersed using simple mixing equipment. Furthermore, use of the liquid bread improvers reduce the generation of potentially harmful dust caused by manual addition of the dry improver to what is commonly an open vessel in most bakeries.
One example of a pumpable bread improver is described in Australian Patent Specification No 631683. This bread improver comprises a mixture of fat and bread improver ingredients and is characterised in that the ingredients including solid fat particles are dispersed in a liquid glyceride oil. However, the oily nature of this product can be a disadvantage because it can make CIP (cleaning in place) very difficult and could give rise to contamination problems in the resulting bread. The bread improver described in AU631683 also does not provide an aqueous phase for water soluble improver ingredients and further, exhibits poor flexibility because
the required ratio of oil to oxidising agents varies for different bakery products.
The present inventors have developed a liquid bread improver (LBI) which promises to overcome or alleviate some or all of the disadvantages of the prior art.
Accordingly, the present invention consists in a liquid bread improver which comprises a water slurry of a composition comprising up to 40% (w/v) of a mixture of bread improver ingredients and the balance water, the mixture of bread improver ingredients comprising;-
(i) edible oxidising agent(s) 0.2-5% (w/w)
(ϋ) edible substance(s) containing or capable of 0-1.0% (w/w) producing -SH groups
(iii) fungal enzyme 50-300 SKBU/lOOg LBI
(iv) malt flour 0-40% (w/w)
(v) emulsifier(s) 0-40% [w/w)
(vi) inorganic mineral salt(s) 0-20% (w/w)
(vii) inactive dried yeast 0-4% (w/w)
(viii) yeast extract 0-10% (w/w)
(ix) edible oil(s) 0-40% (w/w)
(x) edible water soluble gum 0-5% (w/w)
(xi) carrier material balance.
Preferably, the mixture of bread improver ingredients is present at concentration of 10-40%, and more preferrably 10-25% w/v.
The bread improver ingredients may be selected from, for example, emulsifiers. oxidising agents, reducing agents, enzymes, sugars, salts, food acids, acidity regulators, vitamins and milk solids.
As will be understood the LBI comprises a water slurry of bread improver ingredients mixture comprising at least 0.2-5% edible oxidising agent(s) and 50-300 SKBU/lOOg LBI fungal enzyme with the balance being carrier material. It is, however, preferred that the bread improver ingredients mixture further includes at least one ingredient selected from the following:
edible substance(s) containing or capable of producing -SH groups malt flour emulsifier(s) inactive dried yeast yeast extract edible oil(s) inorganic mineral salt(s) edible water soluble gum
In yet another preferred embodiment of the present invention the ratio of carrier material to other ingredients in the bread improver ingredients mixture is in the range of 5:1 to 1:2 and more preferably in the range of 3.3:1 to 1:1.
In a further preferred embodiment of the present invention the bread improver ingredients mixture comprises 1-3.0% (w/w) of at least one edible oxidising agent, 2.5-6.0% (w/w) fungal enzyme, 12-35% (w/w) malt flour and 5-12% (w/w) of at least one inorganic mineral salt with the balance being soya flour.
Edible oxidising agents suitable for use in the LBI according to the invention include coated and/or uncoated agents, and particularly, coated or uncoated ascorbic acid.
Suitable edible -SH group containing or producing substances may be sodium metabisulphite, cysteine, glutathione, thioglycollic acid or edible salts thereof.
Suitable fungal enzymes for use in the present LBI include powdered or liquid preparations containing amylolytic and/or proteolytic and/or hemicellulase enzymes. Examples include Maltase C premix and Natura 25/100.
The emulsifiers which can be used in the present LBI include solid or liquid emulsifiers and particularly, monoglycerides, mixed mono and diglycerides, tartaric esters of mono and diglycerides, and sodium stearyl esters of lactic and oleic acids. Inorganic mineral salts which may be included in the present LBI include phosphates of calcium or ammonium, or ammonium chloride. Preferably, tricalcium phosphate is included in the LBI.
Edible oils which can be included in the LBI according to the present invention include various oils of vegetable origin, such as soya bean oil, cottonseed oil, corn oil, peanut oil, sunflower oil and sesame oil.
The LBI according to the present invention may also include a water soluble gum such as xanthan gum.
The carrier material may comprise treated/untreated flour and/or starch from wheat, corn, maize or sorghum. Most preferably, the carrier material is soya flour.
In a preferred form of the present invention the liquid bread improver comprises a water slurry of a bread improver ingredients mixture comprising:
Ingredient Amount f %1 f w/wl
Ascorbic Acid 1.0-2.5
Coated Ascorbic Acid 0.1-0.5
Fungal Enzyme Premix 1.5-3.5
Hemicellulase 0.5-2.5
Diacetyltartaric acid esters of monoglyceride 20-35
Sodium stearoyl lactylate 5-10
Sova Flour balance
The LBI according to the invention is a water slurry which may contain some of the compositional components in solution form. The LBI of the present invention generally shows good stability (e.g. at 4°C for periods of at least three weeks). The LBI is pumpable and, accordingly, may be used in rapid dough processing systems to produce bread or bakery products with improved volume, good external crust appearance and improved internal crumb characteristics such as softness and texture.
The LBI according to the present invention may be manufactured by forming, by conventional techniques, a water slurry of a pre-formulated dry or wet bread improver ingredients mixture. To avoid settling of the solid content of the LBI, regular agitation of the storage vessels may be carried out.
It is to be understood that the invention further relates to methods for producing a liquid bread improver of the present invention.
In order that the nature of the present invention may be more readily understood preferred forms thereof will now be described with reference to the following Examples.
EXAMPLES
In each of the examples set out below where the liquid bread improver includes an emulsifier the emulsifier(s) is homogenised in approximately 75% of the water. The remaining components of the bread improver ingredients are then added to the homogenised emulsifier. The remaining 25% water is then added and proper dispersion of the ingredients is ensured by mixing with a high speed mixer. Where the liquid bread improver does not include an emulsifier the bread improver ingredients mixture is simply added to water and mixed.
Example 1- Bread Improver Composition
A mixture of the dry elements of the LBI composition (a premix) was prepared according to the following:
INGREDIENTS %_
Ascorbic Acid 1.2
Coated Ascorbic Acid 0.2
Maltase C Premix 1.67
Malt Flour 15.5
Natura 25/100 1.25
Tricalcium Phosphate 5.0
Wheat Flour 75.18
(I) Stability Trials
The stability of various baking ingredients were tested by preparing a water slurry and storing the product at 20-25°C for a set period of time. Trials were as follows: Trial 1 Slurry bread improver premix only in water (80gm bread improver made up to 400gm with water). Storage stability period 3 days. Trial 2 A repeat of Trial 1 but storage stability period 6 days. Trial 3 Slurry of bread improver premix and salt (80gm bread improver,
160gm salt made up to 800gm with water). Trial period 3 days. Trial 4 Slurry of bread improver premix. salt and calcium propionate (CP)
80gm bread improver, 160gm salt, 16gm calcium propionate made up to 800gm with water). Trial period 3 days. Trial 5 Repeat of Trial 4 but storage period 6 days.
Trial 6 Repeat of Trial 5 but adding azodicarbonamide (ADA). Period of trial 3 days.
The slurry pH was also monitored for Trials 2,3 and 4. Results:
The results for Trials 1-6 are presented at Tables 1-6, respectively. The proof times and oven spring data are also provided in graph form at Figures 1-6.
Trials 1 and 2 show that basic non-bromate MDD improver is stable for 6 days at 20-25°C.
Trials 4 & 5 show that proof time in the presence of CP is stable for 6 days but oven spring fall off occurs between 3 and 6 days storage. Trial 6 was discontinued after 48 hours due to inferior loaf characteristics being obtained with the presence of ADA in the slurry. pH is relatively unchanged over the storage period for Trials 2-4.

Table 2 (Trial No 2)
Table 3 (Trial No 3)
Table 5 (Trial No 5)
Example 2 Trials with and without flour: Results:
Table 7 A & B outlines results for two 4-day trials. Table 7A outlines results for the basic above mentioned liquid bread improver including salt but with and without flour. Table 7B relates to liquid bread improver with and without flour and also in the presence and absence of salt.
Using liquid bread improver without flour filler results in decreased bakery performance. This is usually illustrated by loss of oven spring or a lower internal bread score or in some cases both. Because flour has a buffering action, detrimental bakery performance could be due to lower solution pH, e.g. pH of liquid bread improver non flour based (plus salt) was 3.5. pH of liquid bread improver flour based (plus salt) was 3.9.
Table 7A
Table 7B
Table 8 provides baking results for trials where the level of coated ascorbic acid was varied from 0.2 to 0.4%. The results indicate that the control level of 0.2% gave the best overall results as increasing coated ascorbic acid further opened up the internal texture of the final loaf.
Table 8
Storage trials were conducted on LBI by storing the LBI at 4°C for varying lengths of time and comparing its performance with a fresh Diamond sample performance each time.
Trials of the liquid bread improver containing emulsifiers (DATEM 12.0%, SSL 3.6% on wet improver weight) added as emulsions to the other components were carried out for 4 weeks at 4°C. Soya flour replaced wheat flour in one formulation. Results
Baking results are summarised in Table 9.
Both wheat and soya flour based formulations gave comparable performance to a commercially available dry Diamond bread improver over 3 weeks at 4°C.
Soya flour liquid bread improver performance is more variable than the wheat flour based product.
Note that loss in performance of liquid bread improver is due to ascorbic acid breakdown in solution so storage containers are covered with foil to keep out light.

Example 5 Use of Xanthan gum Results:
Results in Table 10 show the effect on baking performance of adding cold water soluble Xanthan gum to the LBI.
Product gave similar loaf quality and stability to our standard liquid bread improver, being equivalent to a commercially available product "Diamond" (The British Arkady Co Ltd) after 3 weeks storage at 4°C.
