Acceptability of Dry-Cured Belly (Pancetta) from Entire Males, Immunocastrates or Surgical Castrates: Study with Slovenian Consumers

Abandoning of male piglets castration in the European Union is a challenge for the pork production sector in particular for high-quality dry-cured traditional products. The information on consumer acceptability of dry-cured products from alternatives is limited, so the objective was to test the consumer acceptability of unsmoked traditional dry-cured belly (Kraška panceta) processed from three sex categories, i.e., surgical castrates (SC), entire males (EM) and immunocastrates (IC). Consumers (n = 331) were asked to taste dry-cured bellies from EM, IC and SC and to score the taste appreciation on a 9 cm unstructured scale. After tasting the pancetta of three sex categories, the consumers attributed the lowest acceptability scores to SC, whereas IC and EM received similar scores. Only about a quarter of consumers attributed the lowest score to EM, mainly when boar taint compounds were present. The results of this study indicate that a certain share of consumers was sensitive to taste deficiencies and that the leanness of this product is very important for consumersinfo:eu-repo/semantics/publishedVersio

Molecular biomarkers, Near Infra-Red Spectroscopy and computed tomography as new methodologies applied in TREASURE project to predict the quality of pork and pork products from local pig breeds

Emerging non-destructive technologies are of interest in meat sector science and industry since they allow the characterization of products and quality control throughout processing. Th ree diff erent new technologies described in this paper will be considered in the TREASURE project for the evaluation and prediction of quality of pork and processed products: molecular biomarkers, near-infra red spectroscopy (NIRS), and computed tomography (CT). Molecular biomarkers are single genes, or a set of few genes, whose expression level determined in muscle few minutes aft er slaughter are associated to technological or sensory pork traits. External validation of biomarkers of pork quality, available from previous studies, will be undertaken. NIRS shows a great potential to predict composition of muscle and fat tissues, in particular their lipid content and fatty acid profi les. Th ese novel techniques will be assessed in the project using a wide variety of loin and subcutaneous fat samples from various European breeds. NIRS will also be used to determine chemical composition (water, salt, etc) and physical traits (rheology) of fresh meat and processed products. CT, which corresponds to 3D images constructed using X-ray technology, allows determining the quantity and repartition of lean, fat and bone tissues in living animals and in carcass or cuts. CT will be used to study the distribution of fat and muscle in carcasses and in loin from breeds exhibiting various adiposity levels
