Question: 1 / 400

What is psyllium primarily used for in the food industry?

Flavor enhancer

Shelf-life stabilizer

Bulking agent in high fiber cereals

Psyllium is primarily recognized in the food industry as a bulking agent, especially in high-fiber cereals. Its high soluble fiber content allows it to absorb water and swell, which contributes to a desirable texture and increases the fiber content of food products. This ability to augment bulk can aid in digestive health and improve bowel regularity, making it popular in products marketed for their health benefits.

The other options do not accurately reflect the primary use of psyllium. For instance, flavor enhancers are substances added to improve taste, which is not the function of psyllium. Shelf-life stabilizers are used to extend the period in which a product remains safe and palatable, while color additives serve to enhance or change the visual appeal of food, purposes that are unrelated to psyllium's characteristics and applications.
