Pure-Cote B790 is a modified food starch that has low viscosity and forms a clear flexible film with excellent sheen when it dries. In modernist cuisine, Pure-Cote B790 can be used to make a flavorful, clear and brittle glass wrapper to add a new texture and drama to a dish. As a modern starch thickener, Pure-Cote B790 is also used to thicken juices. Pure cote is also a useful binding agent in cereal and puffed snack coating. Finally, Pure Cote aids de glacage for baked goods and confections, forming a smooth and glossy coating.
Pure-Cote B790 Origin
Pure-Cote B790 is a modern starch thickener made from corn. Pure-Cote B790 is a food grade starch that has been specially modified to produce clear, flexible films.
Pure-Cote B790 Function
Pure-Cote B790 is a modern starch thickener optimized to form clear elastic films as the solution is casted onto a flat surface and dehydrated at low temperatures.
Pure-Cote B790 Applications
To make clear and brittle edible films, make a solution with 10% Pure-Cote B790 and the desired flavored liquid such as tomato water or pineapple juice. Cast the solution into a film onto a flat surface such as a silicone mat or acetate sheet, making a layer of 0.5-1 mm thick. To produce a film with even texture, dehydrate it at the lowest possible temperature and humidity. Pure-Cote B790 films can be dried at room temperature overnight or by using a cool air oven. Finished films and coatings are water soluble, clear, and have excellent sheen. You can make the film more or less elastic by dehydrating less or more.
Pure cote is also a useful binding agent in cereal and puffed snack coating. It is also used as a thickener for juices and as a strong binder for seasoning adherence onto snacks and cereals that resists cracking and peeling.
Finally, Pure Cote aids de glacage for baked goods and confections, forming a smooth and glossy coating.

How to use Pure-Cote B790
Concentration Range: use 10% to make edible films and up to 15% to thicken juices.
Dispersion: Pure-Cote B790 starch can be easily dispersed in cold water but you can also use warm or hot water. Make a slurry of 5%-12% starch in water. Pure-Cote B790 can be preblended with other dry ingredients then added to the vortex of the aqueous solution. Preblending with oils or syrups will also enhance dispersibility of Pure-Cote B790. A typical ratio of starch to other ingredients would be a 50/50 blend.
Hydration: Pure-Cote B790 needs to be heated after dispersion to fully hydrate the starch. A typical slurry of 5%-12% starch in water should be heated to a minimum of 160°F and held for 10 minutes or more. The addition of other ingredients in the starch slurry, or varying the processing conditions, i.e., high shear, can affect the time and temperature required to fully hydrate the starch. To ensure film clarity, the starch must be fully hydrated.
