Texture determination of autochthonous insular sheep cheese

Cheese is the food in which texture is important factor that marks its quality. Numerous studies have confirmed that texture, as well as taste, impact on the perception of consumers in terms of quality and acceptability. Numerous studies have focused on the connection between sensory textural characteristics of cheese with instrumental analysis of tekstural profile. The aim was to analyze the properties of the texture of hard sheep's cheese, and determine the relationship between certain parameters of texture with physical and chemical properties of cheese. For the purpose of instrumental analysis of eight species of hard sheep's cheese from different manufacturers, tekstural profile analysis TPA (Texture Profile Analysis) was used. From the textural parameters examined were hardness, cohesiveness, elasticity, delayed elasticity and resistance to chewing. The hardest of cheeses analyzed was the Spanish cheese (C1) who also had the highest cohesiveness, but it had the lowest fat content. The texture of cheese is very complex and it is impossible to assess from one or two parameters. Results of statistical analysis of measurement data show no significant correlations between the composition of cheese and measured TPA parameters, exception being fat in cheese and delayed elasticity. The only statistical correlations between TPA parameters was between strength and cohesion, and strength and resistance to chewing.
