The present invention relates to a composition comprising citrus fruit fiber having a water binding capacity of from 8 to 25 (w/w) and native starch selected from the group consisting of corn starch, rice flour, sorghum starch, tapioca starch and mixture thereof.

Natural equivalent of chemically modified starch

A process for modifying starches comprises atomising an aqueous slurry of a non-pregelatmised, granular, high amylose starch into an internal chamber in a bi-fluid nozzle of a dryer and treating the atomized slurry, in the internal chamber, with medium pressure steam to produce a slurry of partially treated starch granules followed by discharging the slurry into a reactor where it is contacted with superheated steam to produce dry, particulate, cold water-swelling, intact, high amylose starch granules. The cold water-swelling, intact, high amylose starch granules have greater than 15% solubles. At a starch concentration of 1%, in UDMSO (9 volumes DMSO and 1 volume 6M urea) at 25&#xb0; C., the ratio of apparent viscosity of said cold water-swelling, intact, high amylose starch granules to the apparent viscosity of the parent non-pregelatinised, granular, high amylose starch is lower than 1.00. The cold water-swelling, high amylose granular starch of the invention is useful in the manufacture of food products, especially confectionery products and convenience food products.

Cold water-swelling, intact, high amylose starch granules

A process for modifying starch comprises atomising an aqueous slurry of non-pregelatinised starch into an internal chamber in a bi-fluid nozzle of a spray dryer and treating the atomized slurry, in the internal chamber, with superheated steam to cause partial gelatinisation of the starch. The aqueous slurry containing partially gelatinised starch is discharged through an outlet in the internal chamber into a reactor where the droplets containing the partially gelatinised starch are subjected to further treatment with superheated steam, resulting in the completion of the gelatinisation of the starch in the reactor. Also disclosed is a bi-fluid nozzle for use in spray drying starch which comprises a nozzle body, a nozzle cap and an internal chamber located between the nozzle body and the nozzle cap. The nozzle body comprises at least one atomiser, for connection to a supply of an aqueous starch slurry, for atomising the slurry into the internal chamber and it has at least one inlet, for connection to a supply of superheated steam under pressure, for introducing superheated steam under pressure into the internal chamber. The nozzle cap comprises at least one outlet from the internal chamber. The internal chamber also comprises an interchangeable spacer element with a length of from 10 to 60 mm enabling the length of the internal chamber to be changed. A pregelatinised starch and its use in foods, especially baby foods and infant formulas, feed, pharmaceuticals, cosmetics and personal care products are also disclosed.

Process for modifying starches

A process for modifying starches comprises atomizing an aqueous slurry of a non-pregelatinized, granular, high amylose starch into to an internal chamber in a bi-fluid nozzle of a dryer and treating the atomized slurry, in the internal chamber, with medium pressure steam to produce a slurry of partially treated starch granules followed by discharging the slurry into a reactor where it is contacted with superheated steam to produce dry, particulate, cold water-swelling, intact, high amylose starch granules. The cold water-swelling, intact, high amylose starch granules have greater than 15% solubles. At a starch concentration of 1%, in UDMSO (9 volumes DMSO and 1 volume 6M urea) at 25&#xb0; C., the ratio of apparent viscosity of said cold water-swelling, intact, high amylose starch granules to the apparent viscosity of the parent non-pregelatinized, granular, high amylose starch is lower than 1.00. The cold water-swelling, high amylose granular starch of the invention is useful in the manufacture of food products, especially confectionery products and convenience food products.

The present invention discloses a process for modifying starches comprising subjecting a non-pregelatinized starch and/or flour to a superheated steam treatment, wherein said superheated steam treatment is carried out in a reaction chamber of a reactor, said reaction chamber having at least one inlet and at least one outlet, and wherein the temperature of the superheated steam at the inlet of the reaction chamber is in the range of 150 to 650&#xb0; C., preferably 250 to 550&#xb0; C., more preferably 350 to 450&#xb0; C., and wherein the temperature of the superheated steam at the outlet of the reaction chamber is in the range of 105 to 155&#xb0; C., preferably 115 to 140&#xb0; C., more preferably 115 to 125&#xb0; C. The invention further refers to the starches obtained and baby foods, infant foods, sauces, soups, puddings, dressings, bakery creams, gravies and beverages comprising said starches. Also disclosed is a spray dryer for treating a heat-sensitive material with superheated steam comprising a reaction chamber having at least one inlet for the introduction into the chamber of a stream of superheated steam, at least one outlet for allowing the contents of the chamber to exit and a nozzle for producing a spray of droplets into the path of the stream of superheated steam, said spray of droplets being formed from a liquid containing the heat-sensitive material, wherein the reaction chamber is adapted such that, in use, the stream of superheated steam entering the reaction chamber becomes homogeneously distributed in the chamber and flows in a direction substantially parallel with the internal wall of the reaction chamber.
