A food product may contain a modified starch so you can say that yes a modified starch is a food product. A Soya bean is used to create the thin sheets of paper that are used to hold Sushi together, and they may contain a modified starch to give them the texture required.
Starch derivatives are the same thing as a modified starch. Theses derivatives are used to treat native starch and change the physical aspects of it, the enzymes, or the chemical aspects of the original food product.

In the instance of the soya bean being created into a sheet a starch derivative that contains phosphate will allow the product to be able to absorb additional amounts of water and keep the ingredients together. The shells of jelly beans are created using the same types of derivatives.

Some of the more common derivatives include the following:
• Hydrogen peroxide creates a bleached starch
• Hydrochloric acid reduces the viscosity
• The amylase enzyme will degrade the original starch and result in such sweeteners as glucose, high fructose corn syrups, and in glucose syrups

There are many different reasons why these derivatives are added to the original product. One of the purposes this is done for is to create the pre-gelatinized versions that are in things like the instant gravies that you buy or in the cheese sauce packets inside products like macaroni and cheese dinners. These are designed so that when they are combined with boiling water they will thicken but will not become lumpy.

The toppings that are placed on commercial pizzas are treated so that they will thicken when they are placed into the oven. This thickening will cause the toppings to stay where they were put on the top of the pie. As the temperature of the pie cools slightly the ingredients will become runny again.
These derivatives are frequently used to make low fat versions of popular foods like low fat salami. They allow the manufacture to make a product that will have the correct texture and density but may contain as much as one third of the normal amounts of fat.

These derivatives are placed in a frozen food product to reduce the amount of dripping they will do when they are thawed. This is the primary use for the starches that are bonded with phosphate ingredients.

These items are not only used in the many food product samples mentioned, they are also used in things like the adhesive that is on the back of wall paper. Textile printing uses these items containing carboxymethylated starches, and they are placed in medications so that the tablets we place in our mouth will disintegrate in the manner we expect.

There are many different things that we do to make the food that we eat more attractive, and make it preserve better so that we can prepare it ahead of time and sell it to other people. The way that we think food tastes is greatly influenced by the appearance of the item and then by the smell of the item.

A food product http://www.thc.com.my that is meant to be kept in the freezer may contain a modified starch http://www.thc.com.my to prevent it from dripping so much when it is defrosted. The soya bean http://www.thc.com.my is turned into a soya sheet that wraps Sushi and may be treated to make it absorb more water.
