Description
- This is a divisional application of U.S. application Ser. No. 13/587,696, filed on Aug. 16, 2012, which is a divisional application of U.S. application Ser. No. 12/304,492, filed on Oct. 6, 2009 and issued on Mar. 26, 2013 as U.S. Pat. No. 8,404,297, which application is a national stage filing under section 371 of PCT/IB2006/001664 filed on Jun. 13, 2006, each of which is incorporated herein by reference in its entirety.
- The present disclosure is related with the field of crystallization of sweetening products and more specifically, with co-crystallizing sugar and another natural sourced sweetener.
- U.S. Pat. No. 6,214,402, describes a co-crystallization process between sugar and N-{N-(3,3-dimethylbutyl)-L-alpha-aspartyl}-L-phenylalanine I-methylester. This disclosure is addressed to a method for preparing co-crystallized sugar comprising the steps of mixing sugar with water with stifling, heating the mixture to 120° C., seeding the mixture with a pre-mixture comprising N-{N-(3,3-dimethylbutyl)-L-alpha-aspartyl}L-phenylalanine I-methylester and sugar, removing the mixture from heat and allowing it to cool along with vigorous stirring.
- In connection with the state of the art documents, it is important to mention the existing differences. In said document U.S. Pat. No. 6,214,402 the sugar and neotame co-crystallization process was carried out under atmospheric pressure conditions, that is, at high temperatures, in this specific case at 120° C. In the case of the present disclosure, the product is obtained under vacuum pressure, 60 KPa-75 KPa, which corresponds to an operative temperature of 60° C.-75° C. In the latter case, the darkening of the mother liquor is significantly diminished, which darkening is promoted by high temperatures, which enhances the color of the final product.
- On the other hand, in the co-crystallization process of sugar and neotame, the seeding is carried out with the mixture of sugar and neotame being in the oversaturation zone, thus producing a shock seeding, which generates a non-homogeneous crystal distribution at the end of the process. In the co-crystallization process of the present disclosure, the natural sweetener is fed after loading the batch foot in the equipment and this mixture is evaporated until saturation point is reached wherein an amount of powdered sugar and isopropyl alcohol suspension is added. The advantage of this methodology is that the added crystals in the seed, would be those that will be obtained at the end of the process having a homogeneous size and therefore having a lesser size variation coefficient.
- Furthermore, no reference is made to separating the crystals of sugar juice or syrup in the patent for the sugar and neotame co-crystallization; a necessary operation for the obtention of a free-flowing granular product, that do not become compacted or compressed.
- In the co-crystallization process of a preferred embodiment of the present disclosure, a starting liquor or syrup may have a brix of 55°, and may come from a white sugar melting, clearing, bleaching and filtering process, which generates a stock material having a better quality. U.S. Pat. No. 6,214,402, discloses a sugar and water mixture having 67° brix, with no previous treatment that improves or changes the characteristics of the solution.
- Finally, the present disclosure uses natural sweeteners and, besides, there is the possibility of adding some other aggregate which gives a special characteristic to said product.
- U.S. Pat. No. 4,362,757 describes a sugar crystallized product containing a heat sensitive substance, an acid substance or an inverted sugar. This crystallized sugar product is dry, granular, free flowing that does not become compact and is dispersible in water. The crystallized sugar products are formed in two steps: preparation of a sugar pre-mixture which is dry, granular or transformed with a heat sensitive substance, an inverted sugar or an acid, then it is crystallized through the concentration of the sugar syrup, adding a determined amount of pre-mixture and subjecting the mixture to impact.
- The present disclosure has notable advantages over the U.S. Pat. No. 4,362,757, because in the latter the work is done at a high temperature between 124 and 149° C. (255 and 300° F.), which increases the solubility of sucrose in water, causing the oversaturation of 95-98% of solids. In the present disclosure, the maximum operative temperature is 75° C. and its saturation step is reached in a percentage of solids between 79-81%. The process conditions have a direct impact on the final product. The present disclosure radically improves the size distribution of the sugar crystal. The present disclosure decreases the effect of temperature on the color of the final sugar and on the sugar juice or syrup resulting from the centrifugation process. The present disclosure improves the homogeneity of the natural sweetener and the aggregate in this case, due to the fact that the crystallization is carried out under a controlled and regulated manner, thereby avoiding oversaturation that leads to the generation of new sucrose crystals that do not contain the sweetener or the aggregate. This control and regulation of the temperature is done through vacuum in the equipment and constant conditions of heat through water steam. In the mentioned US patent the oversaturation is controlled by removing the heat through water jackets or forced air flow, instead where the process can go out of control.
- The present disclosure relates to a new product formed by sugar which is co-crystallized along with other natural sweetener product and, optionally, another aggregate, said product has 100% homogeneity, increases the sweetening power by one and a half and fifty folds when compared to that of sugar and, furthermore, being a natural product it does not cause any harmful effects on the organism. In addition, the obtained sub-product in the centrifuging process is useful by obtaining a low calorie liquid sweetener.
- The disclosure is addressed to the preparation process of a sugar and a natural sweetener co-crystal and, optionally, another aggregate and to said product. The process is related with co-crystallization of sucrose with a natural sweetener in a vacuum pan under controlled pressure and temperature conditions and with the separation of the crystals from the sugar juice.
- At the end of the process the sub-product of the co-crystallization is used for producing a liquid sweetener having low calorie content such that a high percent of the stock material is used.
- In order to have greater clearness and understanding of the disclosure, the following figures illustrate a co-crystallization process in which:
-
FIG. 1 schematically shows a process in which sugar and a natural sweetener are co-crystallized for producing the co-crystal of the present disclosure and the utilization of the sub-product as a liquid natural sweetener; and -
FIG. 2 shows a flow chart of a co-crystallization process according to some embodiments of the disclosure. - The present description will use the terms in the sense defined as follows:
- Light liquor: that obtained after melting a white sugar and has been subjected to clarification, bleaching with active carbon and filtration processes.
- Cooked mass: Mixture of sugar and mother liquor unloaded from the vacuum pan, which comprises syrup and co-crystals of sucrose and natural sweetener.
- Co-crystallized sugar: is a sugar obtained through co-crystallization of sucrose with natural sweetener.

- Batch foot: is the amount of light liquor and/or syrup enough for covering the calandria of the vacuum pan at the beginning of the batch.
- Brix: Concentration unit equivalent to the percentage by weight of soluble solids containing a solution.
- Vacuum pan: simple effect evaporation unit that operates under vacuum and which consists of a steam driven heating system, a cylinder-shaped body for cooking the mass. Feed tubing, condensates and incondensable gases output, valves and control instruments, dragging separator and condenser.
- Natural sweetener: Product of natural source such as stevia, cactus pier fruit (Opuntia ficus, indica L), Calonil (from the fruit of Mormordica grosvenori), taumatine (from the Thaumatococcus daniellii), corn derivatives and others.
- Stevia: extract from the leave of the Stevia rebaudiana, Bertoni, which contains glycosides Stevioles as active principle (Steviosides, Rebaudioside A, Rebaudioside C and dulcoside A).
- Batch: A batch of cooked mass.
- The co-crystallization process of sugar with a natural sweetener and, optionally, an aggregate that grants some special characteristic to the product, has as important characteristics obtaining a homogeneous, granular, free flowing, non-compactable product which sweetening power is between one and a half to fifty times that of sucrose, thus decreasing the calorie content per ration; in addition, it is a natural product that do not produce any deleterious effect to the human organism.
- In
FIG. 1 , reference number 1 corresponds to the equipment wherein the natural sweetener extract is obtained, optionally, mixed with an aggregate. Reference number 2 shows the vacuum pan wherein the liquor is loaded, an antifoaming agent and the prepared extract are added, under continuous mixing, the mixture is concentrated up to the range between 79° and 81° brix. At this point, the mixture is seeded with the alcoholic suspension and once the crystals are generated the liquor is slowly fed until 100% level is reached with 88° to 91° brix. - The product obtained in 2 (cooked mass) is centrifuged in the equipment identified with
numeral 3. Herein, sugar co-crystallized with natural sweetener and, optionally, an aggregate is produced. Furthermore, a syrup sub-product with the natural sweetener is re-circulated as shown in reference number 2 in order to restart the co-crystallization process. This process is repeated until the syrup color complies with the specifications because during the repetition of this process said syrup tends to become darker. - When the syrup falls out of the specifications due to repeated and successive cocrystallization processes (i.e., the color of the re-circulated syrup is found above 1600 UI-1800 UI), then the process continues with recovering the greater amount of the natural sweetener, taking into account its solubility in order to use the adequate solvent. This step occurs in reference number 4.
- The recovered natural sweetener returns to the equipment identified in 1 wherein said sweetener is obtained and then the process restarts.
- The non-recovered syrup with natural sweetener is further treated in a bleaching step in order to, afterwards, obtain a liquid sweetener product having also low calories.
- Finally, the crystallization process of the present disclosure comprises the following steps:
- Adding an antifoaming agent to the liquor or syrup (batch foot) in order to avoid the foam provoked by the natural sweetener in a percentage of 0.006% to 10% (w/w) to form a sucrose solution;
- Mixing with mechanical stifling the sucrose solution (light liquor or syrup) with while adding 0.1% to 50% w/w of natural sweetener with respect to the amount of produced mass and, optionally, adding an aggregate in order to reach any special characteristic, to form a mixture;

- Adding a powdered sugar suspended in isopropyl alcohol to the concentrate, which is then used as seed for crystallizing the previous solution in the saturation zone. The amount is determined by different variables such as the weight of the crystal in the mass, the initial size of the seed and the desired final size; which relate in the following manner:
-
Suspension weight=crystal weight in mass*((initial size/final size)3); - Feeding the light liquor or syrup in a constant and slow manner into a sugar evaporator, maintaining the crystallized solution in the “meta-stable zone”, in order to avoid the spontaneous generation of new crystals or dilution of those previously formed. This step is carried out until the equipment reaches 100% of its level, wherein the co-crystallized sucrose and natural sweetener crystal has reached a size of 0.5 to 0.7 mm average aperture;
- evaporating the remaining water from the resulting suspension until reaching 88° and 91° Bx;
- unloading the resulting evaporated mass in order to carry out the separation of the crystals from the sugar juice or syrup through centrifuging at a velocity between 1100 and 1300 rpm to form a supernatant comprising the sugar juice or syrup and residual uncrystallized natural sweetener product and a pellet comprising the co-crystals;
- re-circulating a portion of the obtained supernatant at the end of the co-crystallization process (centrifuging) as necessary while it does not loose the color established by the product specifications;
- recovering from a second portion of the supernatant between 1 and 90% of the natural sweetener with a solvent in which said natural sweetener is soluble;
