    The purpose of this research is the utilization of cape gooseberry’s industrial residues to prepare energy bars. The cape gooseberry’s residues were characterized and showed a significant content of fiber, protein and fat, abundant amount of triterpenes and sterols, and an adequate microbiological quality. Eight energy bars were prepared as a result of the combination of three components: cape gooseberry’s residues (10-30%), oat-amaranth mixture (10-35%), and sugar-water mixture (25-45%); in each of these energy bars, physical properties (deformation according to hardness and work) with a Brookfield texturometer, were evaluated and no difference were found (p>0.05)in the different treatments. A sensorial analysis of the treatments showed that there were significant differences among the eight treatments (p>0.05), and treatment T2 (30% cape gooseberry’s residues, 10% oat-amaranth mixture, and 40% sugar-water mixture was determined as the best. It was also determined that the best treatment contains: carbohydrates 71%, protein 7%, fat 9%, and fiber 11%, the presence of traces of phosphorus, potassium, iron, zinc, vitamins A and C, and essential aminoacids (except tryptophan, lysine and cysteine). The product showed a good microbiological quality, and a net cost of $ 0.35 USD per 45 g. of product.
