The present invention relates to a pregelatinized starch having a Brabender hot paste viscosity (HPV) of at least 200 BU when measured at a pH of at most 4.5. The starch is used to provide a viscosity and pulpy texture to a food product and is resistant to processing under extreme conditions of heat, acidity and shear. Examples of food products which highly benefit from the properties of the starch include compotes; sauces and preparations based on tomatoes; meat sauces; gravies; baby foods; puddings; cereals; fruit-juices and fruit-drinks; fruit sauces such as apple sauce; confectionary such as textured gum drops; cookies, crackers, cakes and pastries comprising fruits; soups; and dry powdered mixes which may be reconstituted with water.

The present invention relates to a polymer composition comprising an anionic polymer composite having a synthesized polymer portion and a polysaccharide portion, obtainable by polymerizing vinyl monomers in the presence of the polysaccharide. The present invention further relates to a strength system and methods of production and use in providing a paper product.

The present invention provides a method of producing phosphoric acid crosslinked starch, including adding phosphorus oxychloride sequentially to raw starch slurry under a condition of pH 9 to 12 to cause the raw starch to undergo a phosphoric acid crosslinking reaction, and controlling the pH by sequentially adding an alkaline solution, wherein concentration of the alkaline solution is increased stepwise or continuously between start and end of the phosphoric acid crosslinking reaction. By the production method of the present invention, phosphoric acid crosslinked starch having a low phosphorus content and a high resistant starch content (for example, pea-derived phosphoric acid crosslinked starch, which has a resistant starch content of 80% or more according to a resistant starch measurement method of AOAC official method 2002.02 and a phosphorus content of 0.5% or less) can be obtained.

Modified biopolymers, such as, charge-modified biopolymers, cross-linked biopolymers, and cross-linked, charge-modified biopolymers are provided along with methods of producing and using the same.

The present disclosure relates to pregelatinized starches having a high degree of process tolerance, and methods for making and using them. In one aspect, the disclosure provides a pregelatinized starch having no more than 15 wt % solubles and a sedimentation volume in the range of 15 mL/g to 45 mL/g, the pregelatinized starch comprising starch granules, wherein at least 50% of the starch granules swell but do not substantially fragment when processed in 95° C. water, the pregelatinized starch being in a substantially planar form. In another aspect, the disclosure provides a pregelatinized, drum-dried starch having no more than 15 wt % solubles and a sedimentation volume in the range of 15 mL/g to 45 mL/g, the pregelatinized starch comprising starch granules, wherein at least 50% of the starch granules swell but do not substantially fragment when processed in 95° C. water.

There is described a binding resin for nonwoven fabrics, in particular for manufacturing supports for bituminous membranes, consisting of 100% natural, sustainable raw materials. The resin is an aqueous solution consisting of starch, a crosslinking agent of natural origin and a catalyst.

Modified biopolymers, such as, charge-modified biopolymers, cross-linked biopolymers, and cross-linked, charged modified biopolymers are provided along with methods of producing and using the same.

A starch-containing microsphere has a particle size that exhibits polydispersity with uniform distribution in a particle size concentrated distribution interval. The particle size distribution in the particle size concentrated distribution interval has the following features: equal division of the particle size concentrated distribution interval into n intervals, and a microsphere percentage in each interval is formula (I),

[00001]$\begin{array}{cc}\frac{100}{n}.Math..Math.\%\frac{1.Math.0}{n}.Math..Math.\%,& \left(I\right)\end{array}$

where n is an integer greater than 1. The preparation method of the starch-containing microsphere includes: first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres thus prepared are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 m.
