Definitions
- the present invention belongs to the food industry field, and particularly to the chocolate industry field. More specifically, the invention consists of a lyotropic composition of carbohydrates in fats and the method for producing it. Moreover, the invention consists of different uses of said composition in the food industry. Finally, the process for preparing chocolate or chocolate substitutes from the lyotropic composition of the invention and the product obtained, particularly chocolate with honey and fruity chocolate, are also an object of the present invention.
- Different ingredients are used in the process of preparing chocolate, being cocoa powder, cocoa butter, cocoa paste, cocoa butter equivalent fats, sugar and emulsifier conventionally used. Additionally, there are other additional ingredients which can be added, as long as the Directive 2000/36/EC of the European Parliament and of the Council of 23 Jun. 2000 relating to cocoa and chocolate products intended for human consumption is fulfilled. Said Directive specifies the ingredients and proportions thereof in the different types of chocolates. These different types of chocolate are defined in Annex I of said Directive. This Directive also indicates that the addition of animal fats and their preparations which are not exclusively derived from milk, as well as the addition of flavoring agents which mimic the taste of chocolate or of milk fat, are prohibited.

- sucrose is a disaccharide formed by two sugars (monosaccharides), glucose and fructose, chemically bound together.
- Lactose is also a disaccharide and is formed by the combination of glucose and galactose.
- sugar in crystalline form is a non-crystalline amorphous form. This occurs, for example, when sucrose solutions are dried too quickly and there is no time for the individual molecules to form a crystalline structure as the water is removed.
- Sugar in amorphous form is an important factor to be taken into account in the manufacture of chocolate since it can affect the taste and the fluidity properties of liquid chocolate.
- the surface of amorphous sugar is very reactive and can easily adsorb any taste/flavor surrounding it.
- sugar is ground together with cocoa, some of the volatile compounds of the cocoa can be adsorbed by the amorphous sugar instead of escaping to the atmosphere, which will result in a chocolate with a more intense taste.
- the amorphous state is unstable and in the presence of water it is transformed into a crystalline material. Once said change has occurred, free water remains which is absorbed by the sugar molecules and makes them to bind to one another forming aggregates, which confer a gritty texture to the chocolate (undesirable). Furthermore, moistened sugar has a high risk of being microbiologically contaminated.
- glucose and fructose linked together form the disaccharide saccharose
- these monosaccharides are normally not used per se in the manufacture of products in which the process for their preparation requires mixing polar and apolar substances, such as the preparation of chocolate.
- Glucose also known as dextrose
- crystallizes as a monohydrate is very difficult to dry completely and is very hygroscopic.
- fructose which is naturally present in fruits and in honey, is also very hygroscopic. This hygroscopicity of both molecules hinders its use in the manufacture of chocolate since the moisture which both molecules absorb from the air surrounding them makes liquid chocolate very viscous, since said moisture favors the binding of the sugar particles to one another.
- the present invention achieves the introduction in the chocolate manufacturing process of rarely used sugars such as, among others, glucose and fructose. It thus provides broad alternatives to the chocolate industry, allowing the manufacture of chocolates with sugars from, for example, fruits or honey, and without resulting in an increase of the cost of the manufacturing process.
- Honey is a food with a high energy value ( ⁇ 337 Kcal/100 g) and with an easy digestion since it is almost exclusively made up of simple sugars, which do not require transformations and are directly assimilated, in addition to glucose and fructose, provides other compounds such as vitamins, proteins, mineral salts, etc, which are essential for the good functioning of the organism. Therefore, the consumption of honey is more recommendable than that of sugar.
- Fruit has, in turn, an undeniable reputation from the nutritional and functional point of view, which will result in a better positioning of the chocolates obtained from fruit sugars (object of the present invention) compared with those prepared from purified and crystallized sugars. Since soluble fruit fractions are used among the main components thereof, fructose will be present at a higher concentration. This may be interesting because fructose is one of the sugars with the lowest glycemic index and it has been massively used for years in diets for diabetics and its use is authorized as a sugar-substituting natural sweetener.
- the chocolate obtained by this method does not have a crispy nature like conventional chocolate and is instead comparable to a chocolate cream (Beckett, 2000).

- the product obtained by means of this process has a plastic, homogeneous appearance, its fracturability and hardness being suitable with respect to conventional chocolate, although the product in liquid state behaves like a viscoelastic fluid, its viscosity and fluency limit being too high to be incorporated into the conventional process for preparing chocolate, which makes it uninteresting from the industrial point of view.

- the product obtained is stored under agitation in a liquid phase 20 h ⁇ 1 at a temperature of 40° C. until its tempering.
- the lyotropic concentrate is heated to 45° C., being in a liquid state.
- a stepped cooling is subsequently applied.
- As it cools to 26-28° C. fatty crystals of all types are gradually formed.
- the temperature is raised to 28-31° C., the unstable crystals melt, only the stable ones remaining.
- These stable crystals act as crystallization nuclei, whereby when they gradually cool, all the crystals which are formed are stable.
- the storage temperature between 4-10° C., the satisfactory degree of stability for dispatching and preserving the lyotropic composition is finally achieved.
- the lyotropic compositions described in this paragraph are to be used in liquid phase, they are melted at temperatures greater than 36° C. and are provisionally maintained stored in vats heated at a temperature of 40° C. and agitated at 20 h ⁇ 1 , until their use.
- composition of the final lyotropic composition is 58.5% carbohydrates, 58% of which are the sum of the monomers fructose and glucose, 35.6% cocoa butter, 4.4% water, 1.0% PGPR and 0.5% lecithin.
- the honey is subsequently filtered through heat-insulated plate filters with a filter pore size of 300 ⁇ m, at a pressure of approximately 2 Kg/cm 2 and at 50° C.
- the filtered honey is accumulated in a tank feeding a plate heat exchanger in which the product is subjected to a heat treatment at 79° C. for 2 minutes and 50 seconds, obtaining a pasteurized honey.
- the polar phase is prepared by mixing 1100 g of said pasteurized rosemary honey, the composition of which has 84% carbohydrates and 16% water, with 245 g of water. This mixing is carried out at 30° C. by means of gentle mechanical agitation, 50 rpm.
- the fatty phase is obtained by mixing 510 g of cocoa butter with 7 g of lecithin. This mixing is carried out at 40° C. by means of gentle mechanical agitation, 50 rpm.
- the fatty phase and the polar phase are mixed with agitation at 600 rpm for one minute at 42° C., resulting in a mixture which must be maintained between 34° C. and 42° C.
- the agitation is subsequently lowered to 50 rpm, another 17 g of PGPR are added to the lyotropic concentrate and the product is transferred to the storage tanks, in which the perfect mixing of the emulsifier will be assured by means of gentle mechanical agitation (100 rpm).
- the product obtained is tempered as in Example 1 and unloaded at a temperature of 30.8° C.
- the lyotropic composition obtained is stored under refrigeration at about 10° C. such that it solidifies.
- the product derived from this process can be melted and tempered without observing any loss of quality.
- the composition of the final product is 60.2% carbohydrates, 33.4% butter, 4.5% water, 1.1% PGPR, 0.5% lecithin and 0.4% other components of the honey different from carbohydrates, such as vitamins, minerals and proteins.
- the pasteurized rosemary honey is obtained as in Example 5.
- the polar phase is prepared by mixing 1100 g of pasteurized rosemary honey, the composition of which has 84% carbohydrates and 16% water, with 245 g of water. This mixing is carried out at 30° C. by means of gentle mechanical agitation, 50 rpm.
- the fatty phase is obtained by mixing 510 g of cocoa butter with 6.7 g of lecithin and 8.4 g PGPR. This mixing is carried out at 40° C. by means of gentle mechanical agitation, 50 rpm.
- the removal of the solvent by evaporation is carried out by continuous addition to a jacketed planetary concentrator at 50° C. and an absolute pressure close to 50 mbar. At the beginning, the pressure increases slightly to 75 mbar. At the end of the process, the pressure is between 30-18 mbar.
- the evaporation lasts 2 hours and 364 mL of the solvent are collected, for which there must be a suitable condensation system.
- the lyotropic concentrate resulting from the removal of the solvent has a moisture of 3.7%. During the entire evaporation process, it is maintained under agitation at 200 rpm.
- the agitation is subsequently lowered to 50 rpm, another 9 g of PGPR are added to the lyotropic concentrate and the product is transferred to the storage tanks, in which the perfect mixing of the emulsifier will be assured by means of gentle mechanical agitation (100 rpm).
- the product obtained is tempered as in Example 1 and unloaded at a temperature of 30.4° C.
- the lyotropic composition from rosemary honey is prepared according to Examples 5 or 6.
