The effect of three pork backfat levels (0% vs. 10% vs. 30%) on chemical composition, fatty acid profile and sensory properties on sheep and goat meat sausages was studied. All physicochemical parameters were affected by the addition of pork backfat in both types of sausages. Sausages manufactured with 30% of pork backfat showed the lowest moisture and protein contents and the highest total fat content. The lower a w values in sausages manufactured with higher fat content while in pH happened the reverse situation. The addition of pork backfat modified the total fatty acid profile, prompting a significant drop in the relative percentages of C14:0, C16:0, C17:0, C17:1, C18:0 and TVA (trans-vaccenic acid), together with a marked increase in oleic and linoleic acids. Finally, in goat sausages, the fat content significantly affected sensory parameters: taste, texture and overall acceptability (P b 0.05). As expected, all physicochemical parameters were affected by the addition of pork backfat in both types of sausages.
The present study was a result of a project in co-promotion between 2 breeder associations, an industry unit and a research center. Results indicated that the meat from animals out of quality commercial brands could be useful as processed meat in a product with consumer acceptability. Also these new meat products brought diversity to meat industry to reach new markets and originating 2 new meat brands recorded at INPI (Instituto Nacional da Propriedade Industrial—Natl. Industrial Property Inst.) with the numbers of 489664 and 489662 of National Brands of sheep and goat meat, respectively.
The purpose of the present study was to characterize the dry-cured loin and dry-cured “cachaço” of Bísaro pork and evaluate the effect of the inclusion of olive cake in the animals’ diet on the cured products. For this purpose, forty loins and forty “cachaços” were used, followed by a process of cold curing with controlled ventilation, without adding nitrites or synthetic additives. The dry-cured loin and “cachaço” chemical compositions were significantly different in moisture, total fat, protein, chlorides, ash, and haem pigments. The “cachaço” showed a much higher value of total fat and a lower protein value. Its chloride content was lower and was related to the lower ash percentage. Neither product differed significantly in the water activity and collagen content. The proportions of saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids were significantly different between these products. The dry-cured “cachaço” showed higher values of SFA and PUFA, and the dry-cured loin had higher MUFA content. No significant effect of different olive cakes on diet was observed in the chemical compositions. Both products are of high quality and with good nutritional and physicochemical characteristics, and the introduction of olive cake in the diet did not affect any of the quality parameters analyzed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
