A spice/sweetener composition and a process for manu¬ facturing it
The present invention relates to a spice/sweet- ener composition wherein a powdered spice, for example cinnamon, ginger or clove, and a crystalline sweetener, such as a sugar or sugar alcohol, are bonded together as a free-flowing and dust-free product. A further ob¬ ject of the invention is a process for manufacturing such a spice/sweetener composition.
Finely powdered spices are used both in house¬ holds and in the food industry for many purposes. The dusting and poor flowability of a powdered spice cause problems. A powdered spice is difficult to sprinkle and to dose evenly. In many applications, a powdered spice is used simultaneously with sugar. The problems mentioned above pertain even to such applications.
Cinnamon and granulated sugar are generally used in bakeries and as sprinkling powders, and they are very often used simultaneously. As regards cinnamon, in particular, it is generally known that it dusts and is difficult to sprinkle. These properties complicate the use of cinnamon in household baking and as topping on yoghurt, for example; in the baking industry they cause variation in quality and increase the expenses. In addition, cinnamon and sugar used as icing on bakery products do not always adhere to the surface of a product in a satisfactory manner.
There have been attempts to solve the problems relating to dusting and sprinkling by using water for bonding powdered cinnamon and granulated sugar to each other. These attempts have, however, not been success¬ ful.
It is known to add a small amount of fat to crystalline sugar in such a manner that a thin layer of
fat is formed on the sugar-crystals. The manufacture of a sugar product of this kind is disclosed, for example, in the product brochure 'WITOCANR - For the Manufacture of "Decorating Sugar" ' by Dynamit Nobel AG. According to the brochure, the product can be made of icing sugar or crystallized sugar by adding 5 parts by weight of the melted fat WITOCAN", which is a special kind of hard vegetable fat, to 95 parts by weight of sugar heated to a temperature of about 35 to 40CC while the mixture is stirred. The fat should have approximately the same temperature as the sugar. Thereafter the product is cooled while the stirring is continued. According to the brochure, a moisture-repellent sugar product is thus obtained, said product being almost insoluble in cold water and suitable for use for decorating purposes on bakery products and other food products.
Fat/sugar compositions have been developed for different purposes. It is known, for example, that addition of fat improves the adherence of sugar on bakery products. These compositions do not, however, solve the above-mentioned problems pertaining to the use of a powdered spice.
The object of the present invention is there¬ fore to provide a spice/sweetener composition which is dust-free, free-flowing, of even quality, and thus easy to dose both by sprinkling and by other means. The taste and other properties of the composition must naturally also be suitable for use in foodstuffs.
This object is achieved with a spice/sweetener composition of the invention, which is characterized in that it consists of granules comprising a crystalline sweetener and a powdered spice bonded together with a fat which is solid at room temperature.
A further object of the invention is a process for manufacturing the above-mentioned spice/sweetener
composition, said process being characterized in that a finely powdered spice is mixed with a crystalline sweetener, the obtained mixture is heated to a tempera¬ ture in which the fat to be used is in a melted state, the melted fat, which is solid at room temperature, is sprayed with vigorous stirring onto the mixture in an amount of from 0.5 to 5% by weight of the total amount of the composition to be manufactured, and the obtained mixture is cooled to room temperature with continuous stirring.
The crystalline sweetener in the composition of the present invention may be selected from crystalline sugars such as sucrose and fructose, sugar alcohols such as lactitol and maltitol, and mixtures of sugar alco- hols such as isomalt.
For instance, a crystalline sucrose with an average particle size of from 0.30 to 0.70mm, preferably from 0.36 to 0.40mm, and a coefficient of variation of from 25 to 45% is suitable for use in the manufacture of the spice/sweetener composition of the invention.
Known fats are used in the manufacture of the spice/sugar composition of the invention. The fat must be suitable for use in a food product, odourless, and with a neutral taste. The melting range of the fat must be such that the fat is solid at room temperature but melts rapidly at the temperature prevailing in the mouth. A vegetable fat with a melting range of from 32 to 40°C, preferably from 33 to 35°C, is preferred.
Natural spices may contain active substances, e.g. enzymes, that may have an effect on the shelf life of the fat. Thus, for instance, it has been found that the fat used in compositions containing cinnamon should be substantially free from lauric acid in order for the taste of the composition to remain unchanged during storage and heating. In this specification and the
claims, the expression "free from lauric acid" means that no lauric acid is present in free or esterified form". Examples of fats substantially free from lauric acid are the commercially available fats KASTEX (manu- factured by Unilever), and SP 36 and RP 35 (manufactured by Raisio).
The amount of the powdered spice to be used is not critical in carrying out the invention. Preferably the spice is present in an amount of 3 to 15% based on the total weight of the composition; the spice may, however, be used in an amount of up to 30% by weight of the composition, depending on the desired strength of the flavour and the intended use of the composition.
In the process of the invention, the heated mixture of a sweetener and a spice is sprayed to an efficient mechanical or fluidized-bed mixer, to which melted fat is added by spraying it onto the spice/sweet¬ ener mixture while the mixture is stirred vigorously. Thereafter the product is cooled with continuous stirring to a temperature of from 20 to 25°C or stabil¬ ized to room temperature in a separate step.
The spice/sweetener composition of the inven¬ tion is ready for use as such, pleasant and homogeneous in structure and appearance, and it enables easy simul- taneous dosage of a spice and sweetener. On account of high flowability, the product is also easy to sprinkle. Furthermore, it has the advantageous properties of being dust-free and having improved moisture-repellency due to the addition of fat. A preferred embodiment of the invention is a cinnamon/sugar composition comprising from 3 to 15% by weight of powdered cinnamon bonded to granulated sugar with a vegetable fat substantially free from lauric acid and having a melting range of from 32 to 40°C in an amount of from 0.5 to 5% by weight of the total amount
of the composition. According to the invention, this composition is manufactured preferably by mixing pow¬ dered cinnamon with granulated sugar, heating the mix¬ ture to 35 to 40°C, spraying melted vegetable fat, pre- ferably having a temperature of from 35 to 50°C, onto the mixture with vigorous stirring, and cooling the mixture to room temperature for packing.
Typical applications of the cinnamon/sugar com¬ position of the invention are the use as filling, icing or topping for bakery products, and the use as a sprinkling powder on porridge and yoghurt, for example.
The invention will be illustrated in greater detail by the following examples, which are not intended to restrict the scope of the invention. Example 1
500 kg of a crystalline sugar with an average particle size of from 0.36 to 0.40mm and a coefficient of variation of from 27 to 33%, and 45 kg of finely powdered cinnamon were heated to a temperature of 35°C and inserted in a Lodige FKM 1600D mixer. While the cinnamon/sugar mixture was stirred vigorously, 5 kg of melted WIT0CANR HS fat (manufactured by Dynamit Nobel AG, Troisdorf, Germany), heated to a temperature of 45CC, was added thereto by spraying. Said fat is a vegetable fat which is based on coconut and palm kernel oil and has a solid fat content of about 96% at 20°C and a melting range of from 33 to 35°C. The stirring was continued for five minutes at 41°C, whereafter the product was cooled to room temperature first in the mixer and finally in provisional storage. The cooling/stabilization time was two days before packing. The composition obtained consisted of small particles of even size and was free-flowing and dust- free. It also had an even colour and pleasant taste and mouth-feel. In a storage test at room temperature, how-
ever, off-flavours occurred within two months, in appli¬ cations during heating even earlier. Example 2
The procedure of Example 1 was repeated, but WITOCAN* was replaced by KASTEX (manufacturer Unilever). The obtained composition possessed the same properties as the composition of Example 1 in other respects except that the taste of this composition rem¬ ained unchanged even during heating and storage. Examples 3 and 4
The procedure of Example 1 was repeated, but WIT0CANR was replaced by the fat SP 36 in Example 3 and by the fat RP 35 in Example 4 (both of the fats manu¬ factured by Raisio). The properties of the obtained compositions were essentially the same as those of the composition obtained in Example 2. Example 5
Following the procedure of Example 1, a ginger/sugar composition was prepared. The percentages of the ingredients, based on the total weight of the composition, were as follows: Granulated sugar (average particle size 0.36-0.40mm) 94% Powdered ginger 4,5%
Vegetable fat (KASTEX) 1,5%
The obtained composition possessed essentially the same advantageous properties as the compositions of Examples 2 to 4. Example 6
Following the procedure of Example 1, a liquorice/sugar composition was prepared. The percen¬ tages of the ingredients, based on the total weight of the composition, based on the total weight of the com- position, were as follows:
Granulated sugar (average particle size 0.36-0.40mm) 88%
Liquorice powder 10%
Vegetable fat (KASTEX) 2%
The obtained composition possessed essentially the same advantageous properties as the compositions of Examples 2 to 4.
