Spain is a country of immense cultural and culinary tradition,
wherein customs, varied orography and climate have meant that a
wide range of cheeses coexist, each with their specific type of milk,
curing, manufactured form, format and history. Artisan fermented
food products with a medium or long ripening period, such as
cheese, contain more amino acids than industrially produced
cheeses, due to the high proportion of protein in the raw material
and the activity of proteolytic enzymes and microorganisms
involved in the process (Yvon & Rijnen, 2001). Lactic acid bacteria
(LAB) are essential for the production of fermented foods.
