The study and uses of vital wheat gluten is a long history. In the 6th century, it was recorded on Chinese documents. In 1728, Beccari discovered wheat gluten. It is the substance after starch and other water-soluble components are washed off from wheat flour.
Properties of Vital Wheat Gluten
Vital wheat gluten contains 75-85% protein. It is also a nutritious plant protein resource consisting of eight primary amino acids. Glutamic acid and glutamine counts 35% of the total content of amino acids, while proline counts 16%.
Vital wheat gluten has strong hygroscopicity, viscoelastic extension, film formability, adhesion heat coagulability and liposuction emulsifiability. It has mild and mellow flavor, somewhat has a variety of unique physical properties of grain, meeting multi-functional requirements of food nutrition.
Applications in Food and Feed Industries
As a byproduct of wheat and flour processing, vital wheat gluten and bran is often used as the foundation of high-grade aquatic feeds.
In food industry, it is widely used in bread, noodles, instant noodles production to greatly improve the water absorption ability, viscoelastic extension and then improve the overall quality of the food. Also vital wheat gluten uses in meat products like fish cakes or sausages as water retention agent and enhance the viscoelastic ability. You’ll also find Vital wheat gluten in many edible films.
The studies of its deep processing and functional food become more popular and sometimes the value of vital wheat gluten is higher than the wheat flour. Wheat protein peptide could improve inoxidizability, antihypertensive and immune system, therefore extract bioactive peptides from vital wheat gluten became an import study in its deep processing.
