The objective of this research is to develop a chocolate product fortified with heme iron with the purpose of preventing iron deficiency anaemia. Nutritional anaemia is the most common type of anaemia in Peru and globally; in women of childbearing age, in children and the elderly. Moreover, heme iron from dried porcine blood (HCD) is a source of iron with greater bioavailability than ferrous sulphate and has no side effects. Using an experimental mix type design, it was found that the optimal formula for this chocolate is 17,64% of HCD and therefore 14g of this fortified chocolate is required to reach 25% of the recommended daily dose of heme iron intake in women of childbearing age and equivalent to 4 mg. The experimental design was based on the sensory acceptability of chocolate by women of childbearing age. The independent variables were the HCD content, the bitter content. The content of kiwicha remained constant at 5%. The dependent variables were: taste, appearance and texture. The hedonic test was used to determine the level of acceptability of the chocolate and it was found that the optimal formulation is sensory accepted with a "moderately liked" for the three response variables. It was also found that the level of sensory acceptance of the target population varies slightly from an "I like it lightly" to an "I like it moderately" for the range of variation of HCD proposed in the experimental design. Likewise, it was determined by tests of accelerated aging that this chocolate fortified with HCD and without added preservatives, should be consumed before 5 months from its date of manufacture. This research contributes to society in the fight against anaemia by developing a fortified product formulated within the recommended clinical margins, sensory acceptable, and highly bioavailable. It also contributes to the cocoa industry, since it presents a value-added alternative for cocoa since chocolate was formulated with 60% cocoa Peruvian bitter chocolate. Another contribution of this work is that it provides a practical methodology for the determination of chocolate shelf life. Usually this is a complex problem for most entrepreneurs who want to launch thelr food products to the market and need to reglster in the package the product's shelf life.
