The walnuts macadamia have a high value on the international market due to their almonds nutritional characteristics considered to be an excellent source of energy. The aim of this work was to evaluate the chemical composition and fatty acid profile of 22 cultivars of almond walnut macadamia. The cultivars tested were: 'Edson', 'HAES 788 (Pahala)', 'Beaumont 695', 'Flor Rosa', 'IAC 9-20X', 'HAES 344 (Kau)', 'Cannon', 'IAC 9-20', 'C160', 'HAES 849', 'IAC 4-12B', 'HAES 816', 'Doroti', '791 Fuji', 'IAC 4-20 (Keaumi)', 'HAES 814', 'HAES 722', 'África', 'IAC Campinas-B', 'HAES 246 (Keauhou)', 'HAES 741 (Mauka)' and 'HAES 842'. Moisture, fat, protein, ash and crude fiber were analyzed and also oil extraction and fatty acid profile. The highest amount of protein was recorded in 'IAC 9-20X'. The highest percentages of crude fiber content were observed in cultivars 'HAES 741' and 'HAES 842'. The kernels of all walnut macadamia cultivars showed palmitic and oleic acids.
