Abstract
The purpose of this research was to determine the technical feasibility of extracting amaranth seed oil with butane in a subcritical state and to take advantage of the cake generated. To this end, a type of non-germinated grain was characterized, oil was extracted from a germinated grain and the characterized one, the oil obtained was characterized, and the protein was extracted from the defatted cake of the non-germinated one. It was found that the non-germinated grain was made up of 13.33% protein, 7.24% fat, and 9.02% moisture, the optimum yield of this grain was 91%, for the germinated grain, a maximum value of 6.63% for oil mass. By comparing the characteristics of both oils, higher quality was found in the non-germinated oil, and the maximum protein extraction productivity was 5.15%. Thus, it has been concluded that this extraction method is technically feasible.
