Effect of the wooden vats on traditional cheese characteristics

2017

Wooden vats have been used for centuries to collect and transform milk by farmers and cheesemakers all over the world. Nowadays, the tree species mostly used to this purpose are Douglas fir and chestnut. The use of wooden vats is mandatory for the production of all PDO Sicilian cheeses, such as Ragusano, Pecorino Siciliano, Piacentinu Ennese and Vastedda della valle del Belìce. In the last years, the wooden vats have been deeply explored for the microbiological characteristics and they are covered by biofilms mainly represented by lactic acid bacteria (LAB) entrapped in a polysaccharide matrix. These microbial associations do not include pathogenic species. Up to date, there are no studies …

Analysis of microbiological variation in PDO Vastedda della valle del Belìce cheese during the storage period

2011

The PDO “Vastedda della valle del Belìce” is a Sicilian pasta filata sheep cheese, made from raw milk without starter addition. It is a small round cheese without rind, weighing about 500-700 g. It is cheese is marketed also out of Sicily to allow its marketing and to prolong its shelf-life. The aim of this work was to evaluate the variation of microbiological parameters during the shelf-life period. Then 162 Vastedda cheeses from 18 cheese-making processes in 7 farms have been analysed at different times of storage at 4°C (0, 15, 30, 45, 60, 75, 90, 105, 120 days). Coliforms and E. coli were detected into 7/18 cheese-making processes and their count decreased during the storage period. Ent…

An Investigation of the Shelf-life of PDO Vastedda della Valle del Belice Cheese Subjected to Different Packaging Systems Alternative to Vacuum

2015

The aim of this study was to evaluate the effect of different packaging systems alternatives to vacuum that is commonly applied for PDO Vastedda della Valle del Belice (VdB) cheese, a tipical pasta filata cheese, made with raw ewes’ milk. After production following the traditional cheesemaking protocol, VdB cheeses were packaged as follows: vacuum, paraffin wax and two different Modified Atmosphere Packaging (MAP) consisting of a gas mixture of 70% CO2-30% N2 (MAP1) and 100% N2 (MAP2). Cheeses were stored at 4°C and analyzed (25 g) at time 0 and after 15, 30, 60, 90, 120 and 180 days. All the samples were subjected to microbiological analyses for the evaluation of total mesophilic aerobic b…

Molecular characterization of dominant bacterial population in “Vastedda della Valle del Belice” cheese: preliminary investigation

2010

The sensory characteristics of raw-milk cheeses are linked to the cheese-making process, to the environmental factors as animal feeding and to the biochemical and microbiological composition of the milk. In this report we temped to characterize the microflora in the typical Sicilian historical cheese as Vastedda della valle del Belice. Each cheese was previous subjected to microbial isolation on specific media (M17 and MRS). The colony obtained on the solid medium were subject to biochemical tests and DNA extraction. The microbial diversity occurring in the strains was evaluated by PCR, RFLP and sequencing targeted on 16S ribosomal DNA. A number of closest relatives species of lactic and co…
