In several food preparations, there is a need of some sticky substance to bind the ingredients together to make the recipe. The common example of such recipes is the bread in which, some thing that has this property is required. Alternatively, the edible substance for binding may be required during rightly presenting the food while serving. Therefore, different types of substances are used for this purpose since the historical times. Some of these are the food substances themselves, which are sticky as sugar when mixed with water, gelatin, etc.
However, in addition to this also many special types of edible glues are also manufactured and used in the world. This may be either natural or synthetic.
Most of the times we can make use of the substances those will serve the purpose of sticking. For example, the sugar syrup honey, or the pastes of the floor of wheat etc also work as natural edible glues. They bind the different ingredients together and in addition to this, they are edible products. Therefore, they in addition to just binding the ingredients together also provide nutrition to the body. Among these products, the cornstarch or other starches are now widely being used for this purpose. They are very good binders and in addition to this they do not affect the taste of the food preparation at all.
Whenever we find a need of edible glue, we should prefer the above-mentioned things to the use of the other edible adhesives available in the market commercially.
One of the products obtained from the animals that can be used for this purpose is the gelatin. This is a protein and is derived from the animal sources. It is derived from the skin or the bones of the animals. It is widely used since long in the food recipes as cakes and breads. As it is a protein, it is not harmful to the body.
The other products derived from the animal world are the black fungus. This was originally used in china long back.
Both the gelatin and the black fungus are available in the dry form in the market. They are to be soaked in water for making a paste out of them. Alternatively, they can also be added into the preparations in which they will be boiled in water.
In addition to these natural edible products, some types of products derived from plants are also used as edible glue. These contain carbohydrates or some other substances. Generally, they are polymeric substances. The glues obtained from plants have been in use in many parts of the world since the ancient times. Some of them have their own tastes however, most of these substances are tasteless and therefore they can be used in the food preparations without changing the taste of the food preparations.
Some synthetic polymers have been introduced for use as edible polymers. As they are synthetically prepared, proper care is taken while making them that they do not change the taste of the food items in which they are added. However as they are not natural substances they our body may not be able to digest them. Hence, edible glues must be used in proper proportions.
