Hydrocolloids are been used in a wide range of food products as a thickening agent and have significant benefits. It contains a group of long-chain polymers that have the property of forming gels when dispersed in water. Studies showed that a large number of hydroxyl group increases the affinity rendering to form a hydrophilic compound. Hence, they are appropriately been termed as ‘hydrophilic colloids’ or ‘hydrocolloids’.
Hydrocolloids are used in the food industry in order to modify the rheology of the food system. It includes with its two basic properties of food system namely as flow behavior and mechanical solid property. Various foods like sauces and toppings, salad dressings hydrocolloids are been used as a food additive so as to obtain desired viscosity and mouthfeel. Other than this they are also used in jellies, desserts, ice cream, and jams etc. so as to create the desired texture. Hydrocolloids used in baking increases shelf life, dough conditioning, prevents lump formation, retards staling of bread etc.
In the food industry, hydrocolloids have an array of functional properties as –
- Controlling Crystal Growth of Ice
The process of hydrocolloids been used as thickening agents involve the non-specific entanglement of conformationally disorder polymer chains. It acts as a polymer-solvent interaction. Hydrocolloids used in the food industry include starch, guar gum, locust bean gum etc. The thickening effect depends on the type of hydrocolloids, the food system in which it is used, pH value and food temperature of the food system.
Health Benefits of Hydrocolloids in Food
Along with these properties, there are also various health benefits of hydrocolloids that include reducing the risk of cardiovascular disease and help to treat type2 diabetes. Hydrocolloids contain dietary fibers, when taken in food reduces the risk of cardiovascular disease also lowering down the cholesterol level. Different hydrocolloids like guar gum, cassia gum (cassia tora powder), locust bean gum powder, Deoiled tamarind kernel powder (tamarind gum), fenugreek gum powder, linseed gum powder etc. can be taken as intake for high dietary fiber. Studies revealed that dietary fiber such as Psyllium, guar gum etc. helps to decrease the amount of glucose in the body when taken in a sufficient amount.
Other application of hydrocolloids is to be used to produce edible films on food surfaces as well as food components. This edible film acts as an inhibitor of moisture, gas and lipid migration. Hydrocolloids materials including polysaccharides are used in the formation of edible films and coatings.
