A type of material called beta-glucan is present in the cell walls of bacteria, fungus, yeasts, lichens, and algae. They are also present in some plants, including oats and barley. Many foods, including cheese spreads, salad dressings, sour cream, and frozen desserts, contain beta-glucan as a food additive. The expansion of mushroom farming is the main driving force behind the market's expansion for beta-glucans. Over the projection period of 2021 to 2028, it is also anticipated that rising consumer health consciousness and rising healthcare spending will drive demand for beta-glucan products. Additionally, it is anticipated that the food and beverage industry's growth and the quick change in consumer preferences toward processed foods with nutritional value would act as the primary drivers for the worldwide beta-glucan market. Additionally, the shift in consumer preferences toward the use of nutrient-dense dietary supplements over artificial chemicals and the rise in consumer knowledge of sustainable product sourcing are both boosting the beta-glucan market's expansion.
