Description: LIQUID BREAD IMPROVING COMPOSITION The present invention relates to liquid bread improving compositions and processes for making a dough and a baked bread using said compositions Several compositions have been developed for the easy handling and pumping of liquid bread-improving compositions EP-A-572051 discloses a composition comprising 75-95% vegetable oil 1-5% of a hydrogenated oil and 1-5% of a partly hydrogenated oil 2-20% emuisrfiers including at least diacetyl tartaπc esters from saturated or unsaturated mono- and/or diglycendes (i e DATA esters) and enzyme The average particle size of the particles present in the composition is less than 50um in order to keep this composition storage-stable The disadvantage of this composition is the complexity of the mixture and the sophisticated production procedure WO 99/48377 discloses stable suspensions of a particulate component The enzyme containing bread improving compositions disclosed therein have high oil contents (>80% of the final composition), low fat and/or emulsifier (<2%) and enzyme (up to 10%) It is further stated that the bread improver compositions preferably contain either <2% or >20% emulsifier We have found that with fat and/or emulsifier contents of <2% we were unable to obtain stable liquid bread improving compositions that contain 20-45% NaCI The present invention provides liquid bread improving compositions comprising 30-70% of a vegetable tπgiyceπde oil, 2 5-15% of fat and/or emulsifier, enzyme and at least one other bread improving ingredient In the liquid bread improving compositions of the present invention, the enzyme particles have a particle size larger than the enzyme particles described in pπor art processes are used Other large size particles which can be used are crystals of other bread improving ingredients such as salt (e g NaCI) or sugars (e g dextrose) Particle size can be determined by sieving The liquid bread improving compositions of the present invention are easy to produce and fulfil all the demands with respect to their storage stability which means that the liquid does not separate into two distinct phases including a precipitate (after storage for 2 months at 5 and 30°C) Another advantage of such liquid bread improving compositions is that they can be (automatically) dosed to the basic dough ingredients for bread production flour active yeast (baker's yeast e g cream, dry, instant or compressed yeast) and water In one aspect, the invention provides a storage stable liquid bread improving composition comprising 1 30-70 wt% of a vegetable tπglyceride oil, 2 2 5-15 wt% of fat and/or emulsifier, 3 0 05-5 wt% of enzyme particles whereby 70% of the particles have a size of more than 50 μm, 4 5-50 wt% of other bread improving ingredients, The liquid bread improving composition comprises 30-70% more preferably 45- 60%, most preferably 50-60% of vegetable tπglyceπde oil such as soy oil, palm oil or rape seed oii, most preferred is soy oil The vegetable oil is in a liquid form at temperatures of 5°C and higher The liquid bread improving composition comprises further 2 5-15 wt% of fat and/or emulsifier Preferably, the liquid bread improving composition comprises < 5% fat and <15%, more preferably < 10% and most preferably 2-10% of emulsifier Suitable fats are hydrogenated palm or soy fat Suitable emulsifiers are calcium stearoyl lactylate (E482), sodium stearoyl lactylate (E481) or mono- and diglyceπdes such as E471 or mixtures thereof Most preferred is calcium stearoyl lactylate (E482) The liquid bread improving composition comprises 0 05-5 wt% of enzyme particles, preferably granulated enzyme particles More than 70% of the granulated enzymes have a particle size of more than 50μm, more preferably 90% have a size of 50- 200 μm The enzyme can be an α-amylase, a protease, an amyloglucosidase a (phospho)lιpase, a glucose oxidase, a hemicellulase or combinations thereof The liquid bread improving composition further compπses 5-50 wt%, more preferably 10-45 wt% and most preferably 20-45 wt% of one or more other bread- improving ingredients By other bread-improving ingredients are meant in the present application, those ingredients besides components 1 to 3 listed above and the basic dough ingredients (flour, water and yeast) These ingredients have an additional effect on the dough or bread and can be selected from the following components salt, preferably NaCI, for taste - the salt crystals may have a size between 125-1000 μm, more preferably 80% have a size between 250-600 μm, flour of cereals or leguminous plants e g soy flour (active soy flour contains lipoxygenase, having a bleaching effect), malt flour (for dark colouring of the bread or taste) and wheat flour, wheat gluten, milk constituents such as lactose, whey powder or whey permeate, preservatives such as sorbic acid or sodium diacetate, sugars, flavours, ascorbic acid, inactivated dry yeast A preferred embodiment is a liquid bread improving composition comprising 20-45% NaCI Another preferred embodiment is a liquid bread improving composition comprising 20-45% sugar such as dextrose The liquid bread improving composition can be easily made by adding the ingredients into a production kettle, starting with the triglyceπde oil followed by the emulsifier and the fat The mixture of oil, emulsifier and fat is heated to a temperature between 50-80°C, more preferably to approximately 75°C Subsequently the mixture, after complete melting of the fat and/or emulsifier can be cooled down to e g 20-25°C using a plate heat exchanger Optionally the mixture is subsequently mixed e g for 1-4 hours This mixing improves the storage stability of the final composition Rapid cooling improves the physical stability of the final composition and a cooling time of 10-30 min , preferably 15 mm is therefore chosen The stirring is stopped and the mass is left to rest for 10 mm Finally remaining (solid) bread improver ingredients or dough ingredients are added and optionally mixed for example approximately 5-15 minutes, after which the product is filled into containers for storage In another aspect, the invention provides a process for making a dough which comprises mixing flour, yeast, water and the liquid bread-improving composition of the present invention In a further aspect, the invention provides a process for producing a bread which compπses a process for making a dough as described above and subsequently baking the dough The dough recipe for white bread may consist of wheat flour (3500 g), fresh yeast (70 g), Liquid Bread Improver (LBI) for white bread (175 g) and water (1840 g) The ingredients are mixed in a standard spiral mixer for 350 rounds in the first gear, followed by 1200 rounds in the second gear The temperature of the dough was kept at approximately 28°C The dough is moulded into ball shapes of 890 gram, prior to proofing for 40 mm Subsequently, the dough is moulded for tin bread and final proofing occurs for 70 mm at 34±2 °C and 85±5% RH Baking is performed for 30 m at 270°C top temperature and 280°C bottom temperature The procedure for wholemeal bread is essentially the same, with the alteration that 3500 g of wholemeal flour is used, liquid bread improver for wholemeal bread is used, the proofing occurs in ball shaped moulds of 900 g, and baking is performed for 40 m The procedure for various types of universal breads may be essentially the same as the above described procedure for white bread, however it may differ from this procedure in the addition of extra NaCI (70 g), since this is not present in the LBI-universal Moulding, proofing and baking is the same as for white bread All Fermizyme ® and Levuraline ® products referred to in the following examples are products from DSM Bakery Ingredients Delft, The Netherlands The Fermizyme products were of the BG type meaning that at least 80% of the particles have a size between 63-200 μm as determined by sieving Fermizyme ® and Levuraline ® are registered trademarks of DSM N V Example 1 Liquid bread improver for the preparation of white bread (5 wt% dosage of flour).
