The present invention relates to edible to substitute chemically modified starch. The invention also relates to a method for obtaining specified substitute, which includes fiber citrus and native starch. Finally, the present invention relates to the use of fibers citrus and native starch as a natural alternative to chemically modified starch.
Food manufacturers are constantly looking for ways to get a delicious, natural food product at the lowest cost feedstock. Particularly important was the task of getting the songs from all-natural ingredients. Namely, the consumer, it is important that the starches in food has not been chemically modified, but had the same properties as chemically modified starches.
Indeed, the starches are often chemically modify various reagents with getting starches, for example, having excellent resistance to various processing, such as heating, shearing force, extreme pH levels, and stable during storage. In addition, such modified starches provide the desired product smooth texture, stable viscosity during processing and good shelf life. In contrast, when the processing of the product remodification the diversified starch viscosity falls, lost thickening ability and texturemode properties, and their behavior during storage unpredictable because of the influences to which they were subjected in the process of obtaining food. Heating, shearing force and/or extreme pH, in particular, acidic pH, able to destroy the starch granules and dispersing polymers of starch in the food product. Therefore, unmodified or native starches are usually unsuitable for use in food products subjected to heat treatment. In the prior art has already proposed various solutions, for example, in EP 721471 and EP 1038882 disclosed thermally-inhibited starches and flours that are functionally equivalent chemically modified starches (i.e., stapling).
In EP 830379 and 1159880 disclosed previously gelatinisation in the form of starches, which ingibirovany to obtain the textural properties of chemically cross-linked pre-gelatinizing in the form of starches. In these references, the term "physically" modified starches describes starches that do not contain chemical modifications, but their structure is modified during processing.
Other known prior art solution is completely replaced with a chemically modified starch using citrus fibers in e is Oliseh with low fat content. This solution is appropriate, even if there is some net because fiber citrus are highly functional textureloader material, however, the citrus fiber is relatively expensive material.
Accordingly, there is still a demand for natural ingredient low cost, but have the same functionality as chemically modified starch. The present invention satisfies this need by compositions containing fibers citrus and native starch, its use as a food substance to replace chemically modified starch, and method of reception. The authors of the present invention unexpectedly found that the mixing of the fibers with citrus native starch allows to obtain a product with the stability required for the food industry, such as resistance to shear, along with improving the texture and stability during repeated freeze.

Detailed description of the invention
The present invention relates to compositions suitable for the substitution of chemically modified starch containing citrus fiber with moisture-tie capacity from 7 to 25 (by weight) and native starch selected from the group consisting of corn starch, rice flour, sorghum starch, tapioca starch, flour from wheat, waxy potato starch, free from amylose, and mixtures thereof. In a preferred embodiment of the present invention is used, the starch is a waxy starch, such as flour of glutinous rice.
The citrus fiber used in this image is the situation, are a valuable component that has a relatively high total content of dietary fiber and a balanced ratio of soluble dietary fiber to insoluble dietary fibers. For example, dietary fibers preferably include about 45-50% soluble dietary fibers and from 50-55% insoluble dietary fiber. A balanced range of food insoluble (structural) and soluble (mainly pectin) fibers from the point of view of physiological functionality is an advantage over the fibers on the basis of grain. Citrus fiber according to the invention, preferably fiber orange, even more preferably dry portage orange have an extremely high moisture-tie capacity, which results in a high viscosity, in comparison with VitacelTMthe fibers of orange (available from Rettenmaier). In one of the preferred variants of the present invention dry fiber citrus have a total content of dietary fibers is from about 60 to 85 wt.% (on dry matter) and have a moisture-tie capacity from 7 to about 25 (by weight). Preferably the total content of dietary fiber is at least about 70 wt.%, and moisture-tie capacity is at least about 8, more preferably at least 12, most preferably from 19 to 25. the contents of protein in dry citrus fibers up to 12, preferably from 8 to 12 wt.%.
Fiber extracted from citrus vesicles variety of citrus fruits, including, without limitation, oranges, tangerines, limes, lemons and grapefruit.
Vesicles citrus fruits belong to the cellulosic material, inside of which contains a part of the juice of the citrus fruit. Sometimes the citrus vesicles referred to as a fibrous mass of coarse fibers, machines, cells citrus, floating fibrous mass or fibrous mass. In contrast, citrus flour, obtained from citrus peel, is characterized by the presence of the taste and smell of orange peel and dark orange color, which strictly limits the use of the product. Additional benefits of citrus fibers in comparison with citrus flour is higher total content of dietary fibers (for example, about 72 wt.% compared to 58 wt.%); and higher moisture-tie capacity (such as more than about 8.5 g of water per 100 grams of fiber, compared to 5.5 g/g). The protein content in citrus fibers is typically from about 8 to 12 wt.%.
The ratio of soluble dietary fiber to insoluble dietary fiber is an important factor for the functional properties of citrus fibers. Other important aspects include the degree of grinding (grain size distribution) and drying conditions (drying method). As ravelo, a higher degree of grinding (for example, a finer grading of fibres leads to greater uniformity of the fibers in the solution, as well as reduces the ability to absorb water and reduces melodijas ability compared to the coarser fibers. Preferably the dry fiber citrus fruits receive according to the method described in International patent application WO 2006/033697. In a preferred embodiment of the present invention is a fiber citrus fruits are fiber orange with moisture-tie capacity from 12 to 25, preferably from 19 to 25. Preferably these fibers orange have moisture-tie capacity from 2 to 10, preferably from 4 to 10, more preferably from 5 to 9.
Without assuming theory, the authors present invention believe that they are introduced in combination according to the invention fiber citrus and then subjected to additional processing to act as a protective agent for starch. Of course, the stability of the indicated starch increases, namely the influence of shearing forces. It is believed that this increased stability is due to the fact that fiber citrus inhibit the swelling of starch granules. According to the invention, the higher the moisture-tie and maslodelija ability, the better protected the starch these fibers.In a preferred embodiment of the invention, the fibers of orange in combination with glutinous rice flour are moisture-tie capacity from 19 to 25, melodijas capacity from 5 to 9.
Also the present invention relates to a composition with a weight ratio of fibers to citrus native starch from about 1:10 to about 2:1, preferably from 1:7 to 1:1, more preferably from 1.5 to 1:3,6, and most preferably from 1:5 to 1:2.

This method involves the following stages:
a) mixing fibers citrus and native starch,
b) machining the mixture from stage a) obtaining a homogeneous mixture,
c) heat treatment of the mixture with gentle stirring to a temperature of gelatinization of starch.
For processing of the mixture from stage a) can be used with any method of homogenization, as the degree of hydration of the fibers citrus is not too important.
Suitable mechanical treatment for stage b) is processed in a mixer with a large shearing force, homogenization under high pressure, microfluidizer, sonication high power, etc. While using a high shearing forces, such as, e.g. the measures when homogenization under high pressure, you can get thick fiber particles with lower density. Then the mixture from stage b) is subjected to heat treatment for swelling of the starch granules. This gives the viscosity of the environment; careful mixing is used to obtain a homogeneous mixture, with vigorous mechanical treatment avoids the destruction of the starch granules. The temperature of gelatinization depends on the type of starch; it can be determined by a specialist in the field of technology to which the present invention; however, the temperature of gelatinization of some types of native starch can be found in the literature and, for example, the book by David J. Thomas and Williams A. Atwell, Starches, Eagan Press Handbook Series, American Association of Cereal Chemists, St. Paul, Minnesota (1999), pages 25-30.
The following temperatures:
|The source of starch||The gelatinization temperature (°C)|
Given the limits of the temperature of gelatinization depends on moisture and salt in the environment.
The present invention Rel is referring to the application of the described compositions as additives in food products, forage products, pharmaceutical or cosmetic products. Foods can include drinks, dairy products, ice cream, sherbets and desserts. These drinks include concentrates, gels, energy drinks, carbonated and non-carbonated drinks, syrups. The drink can be any medicinal syrup or any drinking solution, including iced tea and fruit juices, drinking solution based on vegetable juices, lemonades, soft drinks, drinks on the basis of nuts, drinks based on cocoa, food products such as milk, whey, yogurt, buttermilk and drinks based on them. Liquid concentrate can be in a relatively dense form of liquid syrup. The preferred application are soups, dressings, baked goods, spreads, low-fat and sauces. Preferred applications are the sauces Bechamel and tomato sauces.
The combination according to the invention is suitable to add in instant hot foods such as soups; in this case, the specialist in the field of technology to which the present invention should understand that can be applied to other types of starch. Of course, if the mixture is not subjected to heat treatment before adding a soluble product, the consumer will face wrinkle texture, that is as the sand properties. Therefore, to avoid this, you must use pregelatinized starch, for example, the last heat treatment of starch spray drying. Another possibility is the combination of citrus fibers with thermally-inhibited starch in order to compensate for very extreme conditions (e.g. pH of about 3.5 and a temperature above 95°C) or when you want an extremely high viscosity.
In a preferred embodiment of the present invention the combination according to the invention is in the finished product from about 1.5 to about 7 wt.% from the composition, preferably from 2 to 6 wt.% and more preferably from 3 to 5 wt.%. The present invention has the following advantages.
