Namkeen, a popular category of savory snacks in India and other South Asian countries, includes a wide variety of products such as chakri, bhujia, sev, mixtures, and others. These snacks are often consumed as quick bites with tea or during festivals, and their demand has steadily increased due to changing lifestyles, urbanization, and the rise of convenience foods. The production of namkeen is a complex process that involves blending various ingredients to create unique textures, flavors, and shapes. One key ingredient used across many types of namkeen is soya lecithin, an emulsifier that offers a range of functional benefits.
