Cold water swelling starches

Since insoluble ingredients like cook-up starches tend to sediment without agitation, viscosity-increasing ingredients like xanthan gum or cold-water swelling starches are used.

Cold water-swelling starch (CWS) is an instant starch that remains as an intact granule. It offers convenience stability clarity and texture. CWS starches have smooth texture similar to cook-up starch and more processing tolerance than conventional pre-gelatinized starches.

By increasing the viscosity of the brine system, a network is built up that prevents the cook-up from settling.

CWS scratches may be gelling or non-gelling, They may be used in no-cook or cold-process salad dressings providing the thick, creamy mouthfeel in no fat salad dressing.

CWS is dispersible in sugar solutions or corn syrups by rapid stirring; the resulting dispersion can be poured into molds, where it sets to a rigid gel that can be sliced easily. The result is a gum candy.

Cold water swelling starch is also useful in making desserts and in muffin batters.

Usage of Starch

Starch is a complex carbohydrate which is insoluble in water; it is used by plants as a way to store excess glucose.

Starch are by far the most significant polysaccharide in the diet. They are are found in grains, legumes and other vegetables and some fruits in minute amounts.

Starch need to be cooked because raw starch tastes floury and is not easily digested. When starch and water are heated , the water passes through the walls of the starch granules and the granules become swollen and may burst.

This process is called gelatinization - a process in which starch, on heating , absorbs water and thickens liquids.

The major food sources of starch include grains in the form of cereal, pasta, crackers, bread and other baked goods.

Starch is used to produce food extenders and sugars syrups such as maltodextrins, glucose, dextrose, fructose, maltose and hydrogenated derivatives.

Many cooks use starch for such diverse properties as thickening gravies and soups, making a sweet pudding or dusting pastry before cooking.

For dough in breadmaking starch can be used to offset the excessive toughness caused by a strong flavour.

When added t batters for cakes, starch increases the tenderness and softness of the finished goods.

In cookies, it can help to form a tender structure, can sometimes reduce stickiness and oiliness and can bind water to give soft varieties.

Carrageenan in Gummy Candies

Carrageenan in Gummy Candies Gummy candies are included in a large category of confectionary products such as jellies, pastilles, and wine gums. Originally popularize in Europe, these candies were introduced to United Sates in the early 1980s. Current U.S manufacture now includes a myriad of products with various shapes, sizes, flavors, and food applications.

Traditionally the texture of gummy candies is obtained by using various water binding gelling agents, such as gelatin, starch, pectin and gum arabic. After a boiled mixture of sugars has been prepared, it is mixed with the gelling agent concentrated and then processed into various shapes by depositing into starch molds. After forming the shapes, the gummy candies are dried to their final moisture content and texture by stoving. Once the confections are removed from the starch molds and cleaned, they may be passed through glazing that wets the products with either steam or oil. 

Many consumers, especially mature populations, avoid gummy candies because they stick to their teeth. Gummy candies formulated with Carrageenan offer a range of desirable textures from soft, easy to chew to firmer, short-textured candies. Gummies made width Carrageenan provide clean flavor release, decreased set-up time, and heat stability upon storage. 

In addition, Carrageenan offers processing ease in gummy manufacture: It may be dry blended first with sugar and added to the hot syrup mixture. Traditional gelatin or starch based gummies must first include a step for dissolution of these ingredients.
