Description
B8~5 This invention relates to a desserk composition and more particularly to a starch-containing composition in a dried, granular and free-flowing form, which is adapted to disperse instantly ln a hot liquid to form a thickened sauce or dessert. ~-Desserts or sauces based substantiallv on starch with ~
added colour and flavour are well known, of which custard made ~ ~ -from custard powder and hot milk is a particular and well-known example. Custard powder is now normally substantially composed ; :~
of starch, which in order to forrn a custard sauce, whether eventually served hot or cold by the housewife, needs to be fully gelatinized by heat on the addition of hot milk with stirring.
This preparation, however, has to be conducted with great care in order that a smooth, thick sauce of uniform texture without lumps is obtained. In the hands of an inexperienced housewife, this smooth texture may not be readily obtained, since the temperature of starch gelatinization may not be fully attained, and the starch powder may not be properly wetted out. Indeed, it is usually recommended that a small quantity of cold milk or water is first used to form a paste, before the major quantity
added colour and flavour are well known, of which custard made ~ ~ -from custard powder and hot milk is a particular and well-known example. Custard powder is now normally substantially composed ; :~
of starch, which in order to forrn a custard sauce, whether eventually served hot or cold by the housewife, needs to be fully gelatinized by heat on the addition of hot milk with stirring.
This preparation, however, has to be conducted with great care in order that a smooth, thick sauce of uniform texture without lumps is obtained. In the hands of an inexperienced housewife, this smooth texture may not be readily obtained, since the temperature of starch gelatinization may not be fully attained, and the starch powder may not be properly wetted out. Indeed, it is usually recommended that a small quantity of cold milk or water is first used to form a paste, before the major quantity
2~ o~ the hot milk is stirred in, which can be an inconvenient two-state culinary operation. It is often necessary to reheat the rnix. Furthermore, custard powder, being composed of very fine particles~ is not free-10wing, which makes it difficult to dispense in correct amounts. -~
Various methods have been proposed in the past to overcome this disadvantage, but they all make use of additives, such as various hydrocolloids or gelatine, which may not be ~ -otherwise desired to keep the nature of the custard composition ~:
to be sold and consumed.
j~ ;
-: -. .. . . . ~ . -. :, : .
Free-f lowing and more wettable composition~ may be obtained in many products by the process of agglomeration; but this expedient is not readily available for a custard or other sauce based on 100% starch (apart from flavouring and colouring).
A made~up custard by the housewife almost always contains sugar, and an improved custard powder containing both starch and sugar may be agglomerated. Such a product, however, is still not entirely satisfactory, when, for example, the particles may be rather fragile. ~-It has now been found that a superior custard may be prepared in the form of free-flowing granules, which will instantly disperse in a hot liquid to form a thickened, uniform ;`
sauce of the same characteristics as that prepared rom a -custard powder by the two-stage culinary procedure already described.
According to the present invention there is provided a process for the preparation of a dessert composition in a dried, granular and free-flowing form, which comprises admixing starch powder and sugar particles whiIe spraying water in~a ~0 controlled manner on the mixed particles to provide a moisture content of 13 to 18% by weight, granulating the moistened mixture, drying the resultant granules to a moisture content of 5 to 6~ by weight, and grinding and screening the dried granules -~
to a particle size from No. 10 to No. 36 British Standard Mesh.
~he invention also provides a dessert composition in a dried, granular and free-flowing ~orm whenever prepared by a `
process as described above.
In performing the process of this invention, granulation - ~
is accomplished on a mixture of starch and sugar. The sugar ~ ~ -' '`~` ',-' ' . ' 8~
' ' '' '~
should be of similar particle size to the starch powder, normally used, so that commercially pulverized sugar is preferably employed and thoroughly mixed with the starch powder. During the mixing operation, water is sprayed on in a controlled manner, to a final moisture content of the mix which has been found to be critical. Too low a moisture content will not allow the sub-sequent granulation to be satisfactorily performed, nor provide a final product of satisfactory particle strength. Too high a moisture content produces a paste which cannot be satisfactorily -granulated, and may give hard gritty particles. The moistened mix is then granulated preferably by being passed or extruded under a low applied mechanical pressure through small orifices ~for example, of 0.1 inch diameter), to form small roughly shaped pellets or granules. These granules are then~dried to the ... .
equilibrium moisture content for subsequent satisfactory storage of the produce. The dried granules are then ground and screened, so that the final product has a particle range from No.~ lO to No. 36 British Standard Mesh.
Various items of equipment may be used to carry out ~' the process in which the critical aspects are the moisture con~
tent of the mix, the conditions of granulation, e.g., extrusion, and the particle size of the~product. ~If the pressure~of extrusiQn ls too high, though increased hardness of the final , !,~
ma~ be attained, the product may be gritty in texture an make~
up. ~his effect would result primarily from the assoclated ~
heat generated during the extrusion, which it is essential to avoid. Manv extruders, however, act by a continuously applied `, ;~
and relatively high pressure, as~within a taperlng barrel and screw, which are unsatisfactory for the;product of this invention.

The preferred manner of performing the granulation is by apply-ing a relatively low pressure over a short time during the actual extrusion, and not during the total time of residence in the extrusion device. The size of the orifice holes is related to moisture content of the mixture, the higher the moisture content the larger the size of holes that may be used. A few ~-simple trials will readily establish the optimal moisture con-tent within the range of 13 to 18~ by weight to give the product of this invention in the device chosen.
In a preferred embodiment of this invention a mixture of 50% maize starch and 50% of pulverized sugar by weight is blended in a helical ribbon-blender trough mixer with added colouring and flavouring as required. After or during mixing, the correct amount of moisture is sprayed on to the surface of the mixture within the mixer with its blades still rotating to ensure a uniform distribution of the water. Pneumatic spray or other nozzles which provide a fine spray will be found satisfactory for this purpose. The amount of water to be ;-~
incorporated, for a normal starch moisture content of 12~, and ~0 sugar moisture of less than 1% is from 14 to 15% by weight. The ;
.
moistened mixture is then fed to a granulator, for example, a granulator made by the Apex Construction Company ~Rotary Wet Granulator) which has been fitted with a standard screen supplied with this equipment having holes of 0.097 inch diameter. In this granulator, the screen is in the form of a cylindrical vertically~
positioned band, in a chamber fitted with three rotating blades radially shaped so that the moistened mixture carried along by each blade is progressively pushed through the screen holes during the passage of these blades. The space in front of each '-'; ~
~ . . , '. ~.;
S
blade is kept continuously Eilled from a small constant head by an agitator above. Extrusion is therefore intermittent from each of the holes. The inner surface of the screen is clean immediately after the passage of each blade. The three blades ~;
are rotated from a vertical spindle, which also carries the agitator. The moist extruded granules are then dried to the equilibrium moisture content of the mix which is 5 to 6~ by weight. The granules are then ground, for which twin crushing-rolls are suitable. The ground product is then sized by means of a suitable sifter, to give a product of particle size between through No. 10 British Standard Mesh and on No. 36, wlth the average preferably towards the smaller size. The grinding operation should be controlled to give the minimum quantity of fines below No. 36 mesh, but such fines may be further milled . :~
to feed particle size and recycled. Oversize product (i.e., ;
above No. 10 mesh) is recycled to the crushing rolls.
The finished composition on the addition of hot milk (50g to l pint~ disperses very xeadily, and the resùltant made-up custard is smooth in texture and indistinguishable from ~ -~
a product made with a powdered mix of similar composition. The sweetness level of this product is also generall~ acceptable. ;~
Formulations suitable for the compositions of this invention cover a range of starch - sugar mixtures, from 30 to 80~ by weight sugar, with the preferred product at 50%. The ~`
higher proportions of sugar are easier to granulate, but may give an unacceptably high sweetness level, whereas lower pro~
portions of sugar are more difficult to granulate. It will be - ~-appreciated that 100% starch compositions cannot be satisfac-torily granulated.

blender and fed at a rate of approx. 100 kg/l hour in an Apex 52 RACH Rotary Wet Granulator, fitted with a perforated screen.
The diameter of these holes was 0.097 inches. The moist granules were collected in trays and dried in a Proctor and Schwartz forced circulation dryer.
