ResumoVinte e quatro caprinos machos sem raça definida (SRD), com idade entre cinco e seis meses, foram separados em inteiros e castrados, e submetidos por seis meses a duas dietas, uma constituída por uma ração padrão e outra adicionada de farelo da amêndoa da castanha-de-caju (FACC), formando os seguintes grupos: ISC-inteiro sem castanha; CSC-castrado sem castanha; ICC-inteiro com castanha e CCC-castrado com castanha. Avaliou-se o efeito do FACC sobre a oxidação da gordura da carne embalada a vácuo e congelada por três e seis meses a -18°C. Ao final do experimento mediu-se o teor das substâncias reagentes ao ácido tiobarbitúrico (TBARS), expessa em termos de mg de malonaldeído por kg de carne. Após três meses de estocagem não houve diferenças significativas entres os tratamentos (p>0,05 AbstractTwenty four male goats without defined breed, with ages between five and six months were separated in two groups, intact and castrated, and submitted to two diets, one using a standard ration and the other including cashew-nut bran (CNB), to observe the effect of this natural product to prevent the lipid oxidation of goat meat packed in vacuum and freezing stored for tree and six mouths in -18° C. Four groups were formed: Intact without cashew nut bran (IWC); Castrated without cashew nut bran (CWC); Intact using cashew nut bran (IUC); Castrated using cashew nut bran (CUC). The oxidation was expressed in terms of mg (malonaldehyde) / kg (meat), measuring the content of reactive substances to thyobarbituric acid (TBARS). In the third month no difference (p>0,05) was observed among the treatments. In the sixth month the production of malonaldehyde was significative lower (p<0,05) among the animals which consumed cashew nut bran: IUC e CUC presented 0,78 e 0,87 mg of MAD/Kg meat, respectively. The values were higher between the animals that not consumed CNB: IWC and CWC showed 2,22 e 1,57 mg of MDA/Kg meat. These results demonstrated that CNB can reduce the meat oxidation process during long time of freezing storage.Keywords: goat meat, storage, lipids, oxidation. IntroduçãoA oxidação dos lipídios é economicamente indesejável por produzir alterações no aroma e na coloração dos alimentos, além de reduzir seu valor nutricional (Benedicte et al., 1975;Frankel, 1980;Kubow, 1990). É, contudo, em relação à segurança alimentar que a oxidação das gorduras produz seus efeitos mais negativos, já que algumas substâncias http://dx
