专利说明:
The invention relates to a method for increasing the gelatinization temperature of a starch included in an amylaceous composition, a method for obtaining the starch gelatinization temperature comprising short-chain fructooligosaccharides (ScFOS). a starchy composition of high stability to heating and the amylaceous composition thus obtained. The invention further relates to the use of short-chain fructo-oligosaccharides (ScFOS) as a substitute for sugars or sweetening agents and for delaying the gelatinization temperature of a starch of an aqueous composition. Starch is a compound widely found in the diet. The physicochemical characteristics of starch have an essential role in the bakery or pastry for example more particularly during the baking of cakes, the growth of pasta under the action of heat or in sauces, more particularly their heat stability. when cooking. In order to modulate the resistance level of the starches to heat, that is to say in order to modulate the starch gelatinization temperature, the prior art proposes the use of modified starch. In pastry applications, modified starches are generally not used, so another solution to the problem is to be found. Furthermore, the prior art describes the use of certain polyols in the delay of the gelatinization temperature in particular in the context of the replacement of sugar. However, the use of polyols is limited only to sweet products. In addition, the inventors have demonstrated that certain polyols have an inverse effect namely to reduce the gelatinization temperature of the native starch. There is therefore a need for a product allowing the use of a native starch in starchy compositions comprising sweetening filler and intended for cooking to improve uniformity or cooking conditions or in such starchy compositions to be heat stable. The use of FOS in starchy compositions has been described in particular in the replacement of starch in a very particular application that is gluten-free cheese cake (Rodriguez-Sandoval E., Starch / Starcke, 2014, 66, 678 -684). However, such use of FOS was considered as not recommended since the authors conclude that the replacement of a portion of the starch by the FOS in the composition induces a strong reduction of the organoleptic qualities of the cakes obtained. The invention relates to a method for reducing sweetening bulking agents of an aqueous starchy composition having sweetening bulking agents and typically, 15 and 60% by weight of sweetening bulking agents, 60 to 85% by weight of materials. dry said method comprising a step of substitution of 15 to 100% of said scfOS-sweetening fillers preferentially so as to obtain a starch / ScFOS mass ratio of 0.4 to 4, preferably between 0.5 and 3.5. or between 0.6 and 3; more preferably, between 0.7 to 2.5. Preferably, said method comprising a step of substitution of 17 to 75%, 20 to 60%, of 25 to 55%, of 30 to 50% of said sweetening bulking agents with ScFOS. By "starch composition" is meant a composition comprising starch, typically comprising from 0.5 to 50% by weight of starch preferably from 1 to 45%, 1.5 to 40%, 5 to 35%, more preferably, between 15 to 30% of starch. Typically, said starchy composition according to the invention has 60 to 85% dry matter, typically 65 to 80%, preferably 68 to 78% by weight of solids. Advantageously, said starchy composition according to the invention has 70 to 85% by weight of solids, preferably 75 to 85%. By "sweetening filler" is meant an ingredient or a mixture of ingredients providing mass to the starchy composition and a sweet taste. Typically, the sweetening agent is selected from alcohol sugars, sucrose, glucose syrup. According to the invention, said starchy composition comprises 15 to 60% by weight of sweetening fillers, typically 20 to 58% typically, 25 to 50% by weight of sweetening bulking agents. For the purposes of the present invention, the term "sugar alcohol" is intended to mean any hydrogenated derivative of saccharide compounds containing at least one reducing function. Each reducing function of these sugars is converted into an alcohol function by hydrogenation, according to appropriate methods known to those skilled in the art. Typically, the sugar alcohol is selected from maltitol, isomalt, sorbitol, xylitol, erythritol, mannitol, polyglucitols, polyglycitols, hydrogenated starch hydolyates and combinations thereof. By "glucose syrup" is meant an aqueous composition comprising glucose, typically a mixture of sugar (s) resulting from the hydrolysis of a starch or starch. As used herein, the term "Starch" refers to any material consisting of plant polysaccharides, including amylose and amylopectin with the formula x (C6H10O5), where x can be any number. Typically, a starch selected from at least one of the following botanical origins is corn, wheat, rye, sweet potato, oats, barley, potato starch, tapioca, sago , amaranth, wrinkled pea or sorghum. The starch may be a waxy starch. Advantageously, the starch is a native starch or a chemically modified starch, or any mixture thereof. The term "gelatinization" refers to the solubilization of a starch molecule by cooking to form a viscous slurry. The term "gelatinization temperature" refers to the lowest temperature at which the starch gelatinization process begins. The exact temperature may vary depending on factors such as plant species and environmental conditions and growth of the plant. The inventors have surprisingly demonstrated that the effect in increasing the gelatinization temperature of starch was much more marked for short-chain fructooligosaccharides (ScFOS) than for inulin or fructooligosaccharides (FOS) or glucooligosaccharides (GOS) or Dextro-oligosaccharides (DOS). By "ScFOS" or "short-chain fructooligosaccharides" is meant beta-D-fructans comprising from 2 to 10 units of fructose, wherein the fructose units are linked by beta-2, 1-glycosidic bonds and comprising the terminal end a single unit D-glucose. Preferably, ScFOS comprise from 2 to 8, typically from 2 to 4, fructose units (GF2, GF3 and GF4). Preferably, ScFOS comprise 32% (w / w) GF2, 47% (w / w) GF3 and 11% (w / w) GF4. ScFOS are conventionally obtained by converting sugar from sugar beets or by hydrolysis of inulin. Such ScFOS are for example marketed by BEGHIN MEJI under the trademark ACTILIGHT® or the company BENEO p95, Orafti, Wijchen. The "starch / ScFOS ratio" corresponds to the mass ratio of starch and ScFOS included in the composition. The "moisture content" can be evaluated by chemical titration methods (eg Karl Fischer titration), by methods of determining mass loss on drying (using a vacuum oven or no and temperature controlled). Typically, the starchy composition comprises a water activity (Aw) having a value greater than 0.7, typically between 0.8 and 0.99, in particular between 0.85 and 0.98, typically between 0.9. and 0.96. The water activity of a product is a concept that is well known in the food industry, this magnitude, abbreviated as Aw, measures the availability of water in a sample. Aw is generally measured at 25 ° C by various instruments such as for example AquaLab Model CX-2, Decagon Devices, Inc., Pullman, WA. Such instruments include a closed measuring chamber. Aw is defined as the ratio of the water vapor pressure in the chamber to a sample (P), for example a starchy composition, divided by the pressure of water over pure water (P0). ). Thus, multiplying the water activity of the sample by 100 gives the relative humidity of the atmosphere in equilibrium with the sample. The invention also relates to a method for obtaining a high stability starchy composition at heating at temperatures of 80 to 100.degree. C., preferably 85.degree. C. to 95.degree. C., said starchy composition having sweetening agents. and typically, 15 and 60% by weight of sweetening bulking agents, and 60 to 85% by weight of solids, said method comprising a step of substituting 15 to 100% of said sweetening bulking agents with ScFOS, so as to obtain a starch / ScFOS mass ratio of 0.4 to 4, preferably between 0.5 and 3.5 or between 0.6 and 3; more preferably, between 0.7 to 2.5. By "high heating stability" is meant an improved stability including a strength of the composition, a conservation physicochemical characteristics (including viscosity or non-retrogradation) at temperatures above the starch gelatinization temperature which is included in said composition. The invention furthermore relates to a method for improving the texture of the crumb of a cake or a sponge cake comprising a step of adding ScFOS in a starch / ScFOS mass ratio of 0.4 to 4, preferentially, between 0.5 and 3.5 or between 0.6 and 3; more preferably, between 0.7 to 2.5. The invention finally relates to the use of short-chain fructooligosaccharides (ScFOS) as a substitute for sweetening filler and / or for delaying the gelatinization temperature. a starch included in an aqueous composition. The invention also relates to the use of ScFOS as an agent for increasing the gelatinization temperature of a starch included in an aqueous composition and more particularly an aqueous starchy composition. Typically, an increase of 1 to 20%, preferably 2 to 10%, typically 3 to 7%, of the gelatinization temperature of said starch. The invention finally relates to a starchy composition comprising sweetening bulking agents, from 0.5 to 50% by weight of starch, having from 60 to 85% by weight of solids and a higher water activity (Aw). at 0.8, said composition comprising short-chain fructooligosaccharides (ScFOS) and a starch / scFOS mass ratio of 0.4 to 4. Typically, said starchy composition comprises 13 to 50% by weight of sweetening bulking agents. . Typically, the aqueous amylaceous composition is a soup, a sauce preferably selected from bechamel or mayonnaise, a pastry preparation, especially for cake, sponge cake or biscuit. The term "pastry preparation" means a dough, an apparatus or a starchy composition intended to be cooked in order to obtain a cake, a biscuit or a sponge cake. This effect is particularly advantageous in the resistance of starch compositions to cooking such as for example pasta to be cooked to obtain cakes or biscuits but also soups or sauces. The invention also relates to aqueous amylaceous compositions comprising more particularly from 0.5 to 50% by weight of starch, preferably from 1 to 45%, from 1.5 to 40%, from 5 to 35%, more preferably from 15 to 30% by weight. % of starch and ScFOS so as to obtain a starch / ScFOS mass ratio of 0.4 to 4, preferably between 0.5 and 3.5 or between 0.6 and 3; more preferably, between 0.7 to 2.5, said composition can be a sauce, a soup or a cake or biscuit dough.

Protocol for obtaining cakes 1.1. products Type 45 wheat flour supplied by the Grands Moulins de Strasbourg The fibers tested are the following: short-chain fructo-oligosaccharides (ACTILIGHT® 950S) marketed by BEGHIN MEIJI, Fructooligosaccharides (ORAFTI® L95) marketed by BENEO, Dextro-oligosaccharides (NUTRIOSE®) sold by ROQUETTE FRERES, -Polydextrose (LITESSE® ULTRA ™) marketed by DANISCO, -Galacto-ologosaccharides (Vivinal GOS), marketed by Friesland Campina-Inulin (ORAFTI® GR) marketed by BENEO. 250 Béghin Say superfine semolina sugar is marketed byTEREOS Water 1.2. Protocol The tests were carried out by mixing Type 45 wheat flour, sugar and / or fibers with water. The other constituents of the recipe, namely eggs, fat, leavening powders, flavorings, emulsifiers were removed from the formulation. Their proportions being constant from one trial to another, their impact is considered identical and vanishes from one test to another. On the other hand, they have a more limited contribution to the gelatinization temperature of starch than sugar and other sweetening products. A paste with 72% dry matter is obtained, which corresponds more or less to the dry extract of a conventional formulation of four quarters (or cake or yellow paste). The ingredients are weighed and mixed manually before any viscosity measurement. The different fibers are tested in substitution of sugar because of their sweetening power. Different levels of substitution are tested, between 30% and 100% sugar substitution. The basis of calculation is performed on the dry matter of each component. The added water is adjusted to obtain a solids content of 72%. The cooking conditions are the same for the entire study. The temperature gradients are set according to the following parameters: from 25 ° C to 90 ° C at 3 ° C / min, the temperature is maintained at 90 ° C for 1min, then 90 to 50 ° C at 3 ° C / min . 2. Viscosity measurement, measurement of the gelatinization point The prepared mixtures are analyzed using a viscometer (Viscograph Type E Brabender) according to the following protocol. The sugar / fiber ratio is adjusted according to the level of substitution sought, the water is added so as to obtain a dry extract of 72% in all the tests. The flour / sweeteners ratio is constant in all tests. The mixture is made in the Viscographe cup and mixed vigorously with a spatula before starting the analysis. After stabilization at 25 ° C for 6 minutes, the sample undergoes a temperature ramp from 25 ° C to 90 ° C at a rate of 3 ° C / min. After holding at 90 ° C during Iminute, it undergoes a temperature drop of up to 50 ° C at the same speed, ie 3 ° C / min. Some tests were stopped before reaching 90 ° C, the viscosity of the dough becoming too great. The analyzes are done in duplicate. The use of Viscograph E makes it possible to measure viscosity according to the chosen cooking parameters. The determination of the starting point of the gelatinization is made possible by a slow parameterization of rise in temperature. We speak of gelatinization point (Starting Gelling Point or SGP) whose unit is the degree Celsius (° C). The gelatinization point is determined by the sudden increase in viscosity of the mixture. When the starch (contained in the flour) is brought into contact with an excess of water at a temperature above 60 ° C, it undergoes irreversible swelling which causes an increase in the viscosity of the medium. The gelatinization temperature is dependent on the botanical nature of the starch and the water content of the medium. The addition of sweetening products or fibers induces a competition for water between the various elements of the medium, flour and sweeteners or fibers. The delay of the gelatinization temperature of the starch will result in a larger volume of cake, since the structure given by the starch is set later. Indeed, during the baking step, a significant amount of water must escape from the dough in the form of steam. If the structure of the cake is frozen too early, the water can not escape and resulting in the formation of a compact and moist crumb. The analysis of the evolution of the gelatinization temperature as a function of the type of fibers and of the fiber concentration made it possible to demonstrate a linear correlation between the gelatinization temperature and the fiber concentration. This correlation is verified for a 95% confidence interval, except for GOS, for which linearity is not demonstrated. In order to verify the impact of the gelatinization temperature on the organoleptic qualities of the cakes, correlations were made with finished products, in particular the specific volume of the cake after cooking. Example 1 Effect of inulin on the retardation of the starch gelatinization point The study model used is cake. The fibers tested are the following: - DOS (Dextro-oligosaccharides) (NUTRIOSE® marketed by ROQUETTE FRERES), - Polydextrose (ULTRA® LITESE marketed by DANISCO), -GOS (Galacto-oligosaccharides) (Vivinal GOS), marketed by Friesland Campina, - Inulin (ORAFTI GR® marketed by Beneo). The tested formulations are shown below. Table 1: Composition of sugar-tested formulations tested by DOS, GOS, inulin and polydextrose at levels ranging from 20% to 100%. Aw of the 20, 30, 50 and 100% sugar replacement compositions was evaluated at 25 ° C by the AquaLab Model CX-2, Decagon Devices, Inc., Pullman, WA. The measured AW of the compositions are as follows 0.94 (+/- 0.01) for 20% sugar replacement; 0.94 (+/- 0.02) for 30% sugar replacement, 0.94 (+/- 0.02) for 50% sugar replacement and 0.92 (+/- 0.02) for sugar 100% sugar replacement. The evolution of the gelatinization temperature according to the type of fiber (namely inulin, DOS, GOS or polydextrose) and fiber concentration is shown in Figure 1. Thus, reading the results it is observed that as the fiber concentration increases, the gelatinization temperature is increased. This means that overall the fibers retard the gelatinization temperature of the starch, but for the same concentration, the increase in temperature is not the same for all the fibers. In addition, compared to DOS, GOS and polydextrose, inulin has the greatest ability to delay the gelatinization temperature. In addition, GOS and polydextrose have only a very weak ability to delay the gelatinization temperature of the starch. Thus, even at high concentration, this power remains too low for their use in the delay of the gelatinization temperature is possible. However, during the tests, it has been demonstrated that the addition of inulin in the preparation induces a strong increase in the viscosity thus limiting the amount of fibers that can be added to the mixture. In fact, it has been possible to substitute only 20% of the sugar with inulin. At a higher concentration, the viscosity of the paste is too high and it is no longer possible to measure the viscometer. Nevertheless, even at 8% of fibers by weight in the 72% dry matter mixture, the inulin makes it possible to delay the gelatinization temperature by 5.5 ° C. This has the consequence of allowing a better development of the cake volume, to improve the structure of the crumb and to improve the soft cake. In addition, the addition of inulin beyond 8% of fibers induces a change in the physicochemical characteristics of the mixture leading to a change in the taste characteristics of the cake after cooking. Indeed, it was found a loss of the organoleptic characteristics of the cake obtained, namely finished products very brown appearance and low volume therefore less pleasant in the mouth. In addition, the sweetness of inulin being very low, the replacement of sugar with inulin drastically reduces the perception of sugar in the finished product. EXAMPLE 2 Reduction or Inversion of the Effect on the Gelatinization Temperature During the Reduction of the Degree of Polymerization of Oligosaccharides In order to reduce the effect observed on the organoleptic characteristics of the cake or on the viscosity of the composition while reducing the loss of the sweet taste noted above, the inulin has been replaced by molecules with a lower degree of polymerization such as FOS (ORFATI® L95) or by monosaccharides (dextrose (MERITOSE® 200) or pulverulent fructose The proportions used are those shown in Table 2 below. Table 2: Composition of formulations tested with sugar substitution by FOS, dextrose, and fructose, at levels ranging from 30% to 100%. The Aw of the compositions was measured as before. The results obtained are as follows: 0.94 (+/- 0.02) for 30% sugar replacement; 0.93 (+/- 0.02) for 50% sugar replacement and 0.91 (+/- 0.02) for 100% sugar replacement. Figure 2 shows the results observed for inulin as well as for FOS which have a degree of polymerization much lower than that of inulin. The degree of polymerization of inulin being from 2 to 60 units, the degree of polymerization of FOS is from 2 to 8 units, the molecular structure of these fibers is very different from that of dextrose or fructose which is only d one unit. The impact on the viscosity of the mixture during the addition of FOS is minimal and has no effect on the organoleptic characteristics of the cake obtained. However, the analysis of Figure 2 shows that FOS have a less significant effect in delaying gelatinization of starch than that observed for inulin. Thus, while reducing the deleterious effect of inulin on the viscosity of the mixture by reducing the degree of polymerization of the fiber used, the effect observed in the delay of the gelatinization temperature is drastically and simultaneously reduced. starch. Moreover, the results observed with regard to the effect of dextrose or fructose on the starch gelatinization temperature go further since an inverse phenomenon is observed which is the reduction of the gelatinization temperature (FIG. 3). Indeed, when the proportion of these monosaccharides increases in the formulation, the gelatinization temperature is earlier. EXAMPLE 3 Effect of ScFOS in delaying the gelatinization temperature while maintaining the physicochemical and organoleptic characteristics of the mixture obtained The effect of ScFOS in delaying the gelatinization temperature of starch was compared with that of inulin , GOS, DOS or FOS in the proportions shown in Table 3 below. The Aw of the compositions was measured as before. The results obtained are 0.94 (+/- 0.02) for 30% sugar replacement, 0.93 (+/- 0.02) for 50% sugar replacement and 0.92 (+/- -0.02) for 100% sugar replacement. The results (see FIG. 5) clearly show that the effect of ScFOS in delaying the gelatinization temperature of starch is certainly slightly lower than that observed for inulin, but it is much higher than that observed for GOS. DOS or FOS. Table 3: Composition of sugar-tested formulations tested by FOS, ScFos, DOS, GOS and inulin at levels ranging from 30% to 100%. It was therefore very surprising to note that the ScFOS which are composed of short chains of tri-tetramers (GF2 (~ 37%), GF3 (~ 53%), GF4 (~ 10%)), have such a power of retarding the gelatinization temperature of the starch. These very short chains of glucose and fructose are both more effective at delaying the gelatinization temperature than longer chain polysaccharides such as DOS, FOS or GOS but also have an opposite effect to that observed for monosaccharides ( dextrose and fructose) that compose them. In order to compare the effect of other reduced oligosaccharides with ScFOS in retarding the gelatinization temperature, maltose (DP2) (GLUCOMALT® 760) was used (Figure 6). The results obtained show that maltose has a beneficial effect on the retardation of the gelatinization temperature. Nevertheless, this effect is less striking than that of ScFOS which is more efficient. In addition, the results show during visual observation of cakes obtained from ScFOS swelling as good or better (at 50 and 30% sugar replacement) than those with 100% sugar. In addition, ScFOS give cakes a softer feel and a smoother crumb.
