Abstract: A roll-in margarine composition with reduced saturated fatty acids content containing 60% to 80% by weight of a fatty phase and 40% to 20% by weight of an aqueous phase containing water, proteins and soluble and/or insoluble dietary fibers is disclosed. The fatty phase consists of 30% to 45% of a vegetable fat rich in stearic acid and 70% to 55% of a vegetable oil. The soluble fibers can be beta-glucans, concentrated algae, pea fiber, potato fiber, psyllium fiber, guar fiber, and the insoluble fibers can be celluloses, wheat fiber, pea integument fiber, carrot fiber and bamboo fiber. A process for preparing the margarine composition is also disclosed.
