Definitions
- the invention relates to aqueous dispersions with hydrolysed starch derivatives. More in particular the invention relates to edible aqueous dispersions containing hydrolysed starch derivatives of low Dextrose Equivalent (DE) as a gelling agent.
- DE Dextrose Equivalent
- EP-A-398 411 spreads comprising gelatin at 1-7.5 times its critical gelling concentration and optionally another gelling agent such as e.g. hydrolysed starch derivatives below the critical concentration are described.
- the hydrolysed starch described in particular is Paselli SA2, which is a maltodextrin having a DE of at least 2, and which is used e.g at 2% level, in combination with gelatin above its critical concentration of about 1 wt% on the aqueous phase.
- Paselli SA2 which is a maltodextrin having a DE of at least 2
- gelatin above its critical concentration of about 1 wt% on the aqueous phase.
- the present invention provides a dispersion comprising an edible fat phase and an aqueous phase containing a hydrolysed starch derivative with a Dextrose Equivalent (DE) of below 2 and at least one gelling agent other than that, wherein the hydrolysed starch derivative is present at or above its critical concentration.
- DE Dextrose Equivalent
- hydrolysed starch derivatives are to be understood products obtained by the hydrolysis (using e.g. acid and/or enzymes as catalysts) of starch, but also similar gelling products obtained by synthesis e.g. by enzymatic synthesis in vitro catalysed by the enzyme phosphorylase. Gelling hydrolysed starch products obtained by hydrolysing vegetable starch are preferred. Sometimes it is preferred to remove glucose and/or di- and/or lower polysaccharides from the hydrolysate by fractionation.
- derivatives also comprises chemically modified products e.g. obtained by esterifying some of the free hydroxyl groups with acetyl groups.
- Suitable starches are mentioned in, e.g., US 4,510,166 and/or EP 554 818.
- a hydrolysed starch derivative to be used according to the present invention suitably has a DE between 0.2 and 1.8, more preferably between 0.4 and 1.6 e.g. from 0.5 to 1.2.
- Hydrolysed starch derivatives which can be used in the practice of the present invention are e.g. product
- the structuring of the dispersion is obtained when applied in amounts as set forth in the claims, the total amount of starch derivative can be kept relatively low, which, in addition to the advantages thereof for taste also provides cost advantages.
- the DE-value of the hydrolysed starch derivatives can be determined by various method.
- the DE values quoted below have been determined by NMR-spectroscopy as described by Gidley, M J in Carbohydrate Research 139, (1985) 85-93 in an article entitled Quantification of the structural features of starch polysaccharides by NMR spectroscopy. It has been established that the data so obtained are in reasonable agreement with the classical "wet chemistry" method described by Nelson, N and Somogyi, M in Journal of Biological Chemistry, 153. 160 and 175 , 61.
- the NMR-method is the yardstick employed below.
- the critical concentration of a gelling agent is the concentration at which that gelling agent will start to form a gel.
- the critical concentration is to be calculated from measu ⁇ rements of the shear modulus of a series of samples con ⁇ taining different concentrations of said gelling agent as described in Br. Polymer J. . 17 (1985) , 164.
- the critical concentration of a specific gelling agent in the aqueous phase of the present dispersion is determined in an aqueous system of a similar composition, with the proviso that no other gelling agents are present, and in which system concentration and water content are varied in order to establish the critical concentration.
- the dispersion of the invention comprises a gelling agent other than the hydrolysed starch of DE ⁇ 2.
- a gelling agent other than the hydrolysed starch of DE ⁇ 2.
- Such gelling (not being hydrolysed starch derivatives) agents can be, e.g. gelatin, pectin, alginate, gellan, a carrageenan, fur- celleran etc.
- synergystic gels i.e. components which are gelling agents when applied in the presence of particular other ingredients, e.g. xanthan, logust bean gum, in the presence of k-carrageenan, and gelling agents such as heat set protein gels are applicable.
- alginate, gelatin and/or pectin in combination with a gelling hydrolysed starch of low DE-value is preferred.
- at least one of the gelling agents is present at a concentration at or above its critical gelling concentration.
- the critical concentration of a combination of gelling agents is to be determined, this is done in a manner analogous to the procedure described outlined above, and whereby the composition of gelling agents considered as if it consisted of one single gelling agent. Accordingly, the composition of gelling agents is kept constant, and the weight concentration thereof is varied as if it consisted of one single gelling agent.
- the preparation of the dispersions according to this invention a rapid formation of crystal structures can be obtained, and, hence, the preparation of these dispersions provide an advantage in the filling of the containers when compared to the prior art dispersions which crystallize slower.
- This rapid crystallization in its turn furthermore provides an improved product stability, as the conditions at which the products are set can be controlled better when compared to slower crystallizing dispersions. Accordingly, the invention allows to prepare products of a more constant quality when produced at commercial scale.
- the present invention provides aqueous dispersions which are in particular advantageous when applied for the preparation of spreads, such as margarines and the like.
- dispersion comprising an edible fat phase and an aqueous phase are to be understood as to comprise fat- continuous as well as water-continuous systems.
- the dispersion may be a fat continuous spread or a water continuous spreads.
- Dispersions such as very low fat spreads e.g. containing 20% or less of fat, zero fat spreads and spoonable dressings are particularly preferred.

- spokeable the rheological parameters of creams, emulsions etc are defined in P. Sherman, Emulsion Science, Academic Press 1968, the term spoonable is not defined therein. According to our definition, a spoonable cream or dressing should display the following rheological behaviour at 5°C.
- the yield value (also called yield stress) should be more than 50 Pa extrapolated from shear rates between 1-300 s ⁇ l (Bingham) ;
- the Bingham viscosity should be less than 500 mPas between shear rates of 100-300 s "1 ;
- the failure to stress should occur at a strain of less than 0.5 radians, preferably less than 0.1 radians.
- Yield values and Bingham viscosities are determined utilising the Carrimed Rheometer. Measurements are performed at 5°C, using 4° cone and plate geometry with a gap setting of 1 mm. The shear stress is increased from zero at a rate of 60 Pa/min, and shear rates are measured until values in excess of 600 s '1 are achieved. The experiment is then terminated. A graph of shear stress vs shear rate is plotted, and a straight line fitted to the curve between the shear rates of 100-300 s 1 . The slope of this line is the Bingham viscosity.
- the dispersion provided is a spread wherein the fat phase is based on highly unsaturated vegetable oils.
- the zero fat spreads according to the invention are plastic in the sense that they can be spread onto bread without tearing the bread.
- plastic spreads will have a stress strain relation with a maximum stress occurring at strain of 0.001-0.5, more preferred 0.01 to 0.3, the maximum stress at this strain being 0.01-100 kPa, more preferred 0.01 to 60 kPa and with a ratio of plastic stress and the maximum stress of 0.1 to 1.
- a suitable method for determining these values is given in EP 298 561.

- the protein level (including gelatin) in spreads of the invention i ⁇ from 0 to 15 wt%, more preferred, 2 to 6 wt%, most preferred 2.5 to 4 %.
- dairy proteins Another option is to include dairy proteins, specifically to improve and enhance flavour release and oral texture.
- the protein is partially a vegetable protein, especially soy bean protein.
- suitable weight ratios of animal protein to vegetable protein may for example be from 10 : 1 to 1 : 10.
- the dispersion of the invention for example a spread may further contain small particles such as herbs and vegetables.

- Spreads of the preferred invention will generally comprise fairly high levels of water, say from 30 to 88 wt% of the composition, more preferred 40 to 80 wt% , most preferred 50 to 70 wt% .
- Water may be incorporated as such, or as part of the other ingredients such as milk etc.
- Such spreads may be fat-continuous in the sense that they comprise a continuous fat phase. Fat-continuous spreads can readily be distinguished from water-continuous spreads by means of conductivity measurements.
- Fat continuous dispersions of the invention can suitably be used as bread spreads to replace e.g. margarine or halvarine, but they can also suitable be used as flavoured spread, for example cheese spreads, meat spreads, nut spreads, sweet spreads or vegetable spreads.
- Spreads of the invention may be prepared by any suitable method for the preparation of fat-continuous spread products.
- a preferred method however involves the mixing of the ingredients, optionally followed by pasteurisation followed by cooling in one or more scraped surface heat exchangers (A-units) to a temperature of 0 to 10 °C, optionally followed by processing through one or more
- this process is conducted in such a manner that the water-continuous composition is maintained at a temperature below the gel setting temperature for at least 100 seconds prior to the formation of the fat-continuous dispersion. More preferably cooling regime and residence time employed till the formation of the fat-continuous dispersion are such that under quiescent conditions a gel having a shear storage modulus of more than 50 Pa. , preferably of more than 70 Pa., is formed.
- the process can be conducted in such a way that the water-continuous composition is converted to small gelled aqueous pieces having a volume weighted mean diameter of less than 150 ⁇ m(microns) prior to the formation of the fat-continuous dispersion.
- this process can be conducted in such a way that the water-continuous composition after having been converted to small gelled aqueous beads is combined with a separate fat-continuous stream to form a fat-continuous dispersion.
- the hydrolysed starch derivative was added to water at 80°C, stirred for 10 minutes, then cooled to 60° and all other further ingredients were added.
- the mixture was passed into an A-unit having an exit temperature of 80°C to pasteurize; the mixture was then cooled down by passage (at 30 g/min) through a series of two A-units, passed through a C-unit and then another A-unit (exit temperature from each unit was 5°C) and finally packed into tubs.
- a very good starch-continuous product was obtained, which had a favourable texture and flavour perception together with a very low calorie content.
- a spoonable fat-free dressing was prepared from the following ingredients.
- the pectin was dissolved in deionised water at 85°C.
- Calcium chloride solution was added to form calcium pectate, followed by the addition of hydrolysed starch derivative and then the remaining dry ingredients such as salt, sucrose and flavour followed.

- the throughput for the process was 50 g/min.
- a spoonable fat-free mayonnaise with a smooth texture was obtained.
- the product showed plastic rheology and was opaque/translucent due to the presence of hydrolysed starch derivative and no titanium dioxide needed to be incorporated.
- the product satisfied the required parameters for a spoonable cream/dressing set out above and had a calorie content which was extremely low.
