Pulses are rich in protein, fiber, iron, folate, and potassium, leading to a significant surge in their popularity in recent years. Manufacturers are increasingly incorporating them into various food products, such as snacks and baked goods, and even enhancing beverages like coffee and chocolate milk with a protein boost. The use of different processing techniques to enhance the flavor of pulses is particularly appealing for manufacturers, as these techniques do not need to be listed on product ingredient labels, unlike flavor masking compounds. However, it is worth noting that some masking compounds may include natural ingredients and flavors.
Research on flavor masking ingredients for pulses is limited, but a review published in the Cereal Chemistry journal last year identified common methods, such as the use of sugars, salts, flavors, and acids. Among these, fermentation was highlighted as one of the most promising processes for flavor enhancement. While many off-flavors in pulses are intrinsic, others arise during harvesting, processing, and storage; therefore, improving handling practices could help reduce undesirable flavors.
Furthermore, companies like Cargill, Ingredion, and World Food Processing are focused on minimizing inherent off-flavors by developing bean and pea cultivars with milder tastes. According to a report from Grand View Research, the global pulse flour market is projected to reach $56.6 billion by 2024, with a compound annual growth rate (CAGR) of about 13% anticipated in North America during that timeframe. In 2015, the bakery and snacks sector accounted for approximately 90% of pulse flour usage, although its application as a beverage additive is gaining traction. Chickpea flour leads the pulse market, capturing over 30% of the share.
In addition to their nutritional benefits, pulses can be fortified with supplements like calcium citrate malate and vitamin D3, enhancing their health profile. This fortification trend aligns with the growing consumer interest in nutrient-rich foods, further driving the demand for pulses in various applications. As the industry evolves, the incorporation of innovative ingredients and processing techniques will likely play a crucial role in the future of pulse-based products.
