Identification and control of moulds responsible for black spot spoilage in dry-cured ham.
2016
The aims of this work were to identify moulds responsible for black spot spoilage in the drying and cellar stages of dry-cured ham processing and evaluate the effectiveness of preventive actions for controlling this alteration. Four mould strains isolated from spoiled hams were identified by morphological characteristics and the ITS and β-tubulin sequencing. Two of them were Cladosporium oxysporum, one was C. cladosporioides and the remaining one was C. herbarum. These spoiling strains reproduced the black spots on dry-cured ham-based media and ham slices. Additionally, the effect of water activity (aw) conditions reached throughout dry-cured ham ripening and the activity of the protective …
Characterization and control of microbial black spot spoilage in dry-cured Iberian ham.
2012
Abstract The presence of black spots on dry-cured Iberian ham surface is an alteration related to microbial population. Although it provokes important economic losses for the meat industry, the microorganisms responsible for this spoilage still remain unclear. The aim of this study was to identify the microorganisms involved in dry-cured Iberian ham black spot spoilage and to study the conditions affecting their growth. Several microbial strains were isolated from Iberian hams spoiled with black spots at the beginning of post-salting stage. However just one strain produced black coloration in both culture media and fat from Iberian ham. This strain was tentatively identified as Pseudomonas …
