The objective of the work was to formulate, characterize and evaluate the stability of a product based on white cachama (Piaractus brachypomus). From four lipid sources (pork back fat, canola oil, olive oil or sacha inchi oil), the one with the highest acceptance rate was selected based on the acceptance index and sensory characteristics. The formulation was optimized using the response surface method; 15 formulations were used in triplicate, evaluating the pH, moisture, colour and sensory acceptance values. The macronutrient composition and lipid profile of the optimal formulation was determined; its stability was evaluated under refrigeration conditions by measuring lipid and protein degradation, changes in colour, texture, changes at the microbiological and sensory levels. It was found an optimal proportion of inclusion of 50% white cachama pasta, 21% canola oil and 23% water. The stability of the final product obtained was 42 days, with 82% of acceptability index. This product could be an alternative to other pâté-type products from other species.
