Abstract
This study aims to evaluate the effect of different dietary fat sources on the quality of a Spanish-cooked meat product Lomo de Sajonia (LSA) and its shelf-life. Forty loins were selected from Iberian pigs fed four dietary treatments containing pork fat (G-1), Greedy-Grass Olive® (GGO) (enriched oleic-acid oil) (G-2), G-2 and high oleic sunflower (G-3), and G-3 plus a mixture of commercial organic acids (Bioll®) (G-4). Loins were manufactured to obtain LSA, and the quality and sensorial attributes were assessed. The shelf life was established according to microbial count and sensorial analysis, which was packed in a modified atmosphere and stored under retail conditions. All meat quality parameters of LSA remained stable in all groups, except fat content and overall liking, which showed the highest values for G-2 LSA. Regarding the shelf life, sensorial attributes remained acceptable in all groups during storage time, while a delay in microbial growth was recorded for the LSA of G-3. According to the results, including GGO in Iberian pig diets could enhance LSA traits, possibly linked to increased assimilation compared with conventional fat sources. However, adding organic acids to the diet did not have the expected effect on improving the shelf life of the LSA.
期刊介绍:
Animal Science Journal (a continuation of Animal Science and Technology) is the official journal of the Japanese Society of Animal Science (JSAS) and publishes Original Research Articles (full papers and rapid communications) in English in all fields of animal and poultry science: genetics and breeding, genetic engineering, reproduction, embryo manipulation, nutrition, feeds and feeding, physiology, anatomy, environment and behavior, animal products (milk, meat, eggs and their by-products) and their processing, and livestock economics. Animal Science Journal will invite Review Articles in consultations with Editors. Submission to the Journal is open to those who are interested in animal science.
