SUMMARY:

Iron is a micronutrient that is bioavailable in large quantities to us, human beings, however its deficiency is considered a public health problem. In Brazil, it is a nutritional problem and mainly affects children, women of childbearing age and pregnant women. Iron deficiency anemia, which is low hemoglobin in the blood and the inability to transport oxygen by red blood cells, affects 90% of cases. Strategies such as food and nutritional education actions, iron supplementation for the prevention and treatment of anemia with the fortification of foods such as wheat and corn flour with folic acid. Microencapsulation in the food industry has been widely used to store a bioactive ingredient, being coated with wall materials forming microscopic-sized particles protected from adverse environmental conditions. Thus, this work aimed to study the formation of the coacervate complex using soy protein isolate and sodium alginate as wall materials, encapsulating iron sulfate and fortifying a biscuit. Within the applied analyzes we were able to confirm the thickness between the biopolymers used as wall material, the high encapsulation efficiency in the chosen options and the encapsulation efficiency and application of the microcapsules in the biscuit we observed that there is no significant difference in color and texture between the samples. without microcapsules and with added microcapsules.
