It is made from raw whole milk produced by ewes of the ‘Lacaune’ breed. Blue cheese is a generic term used to describe cheese produced with pasteurized cow's, sheep's, or goat's milk and ripened with cultures of the mold penicillium. N. Desmasures, in Encyclopedia of Food Microbiology (Second Edition), 2014. Important trademarked varieties include English Stilton, French Roquefort, and Italian Gorgonzola.

The secondary culture, P. roqueforti, is often chosen for proteolytic and lipolytic activities, depending upon the type of Blue cheese, the targeted market, and the desired shelf life. Blue cheese is thought to have been invented by accident when cheese was stored in temperature- and moisture-controlled caves during the Middle Ages. Fig. Paul L.H. It's a sturdy cylindrically formed cheese, beautifully marbled with streaks of blue.

It is often relatively low in fat but has a high sodium content. The body of a blue-veined cheese is white or yellowish with blue-green channels and veins after the growth and sporulation of the mould within the piercing channels and over cavities of the cheese. Proteolysis and lipolysis are enhanced as compared to other cheeses, and flavor compounds are formed from amino acid catabolism as well as fat breakdown. bulgaricus). The purpose of using S. cerevisiae as an adjunct culture would be to make a controlled contribution to aroma formation and proteolysis, as well as creating a stable microenvironment. • Source: Cow's, sheep's, and goat's milk• Origin: France and Italy• Flavor: Traditionally sharp and salty with variations• Rind: Edible. Our editors will review what you’ve submitted and determine whether to revise the article. Gorgonzola is an Italian cheese produced from milk from cows that graze in the pastures of Lombardy and Piedmont. Since we were interested in keeping the array as simple as possible, and as a strategy to increase the information and the number of independent variables, the PLS-DA model of our chromogenic array was fed with not only the data collected at a certain time, but also with the data measured up to the labelled time (ie, for 1.5 h, the data measured at 0.5 and 1.5 were incorporated into the model). After stirring, when the grains of curd are firm enough, molding occurs quickly to ensure a spontaneous cohesion while maintaining openings in the cheese. Food writer, cookbook author, and recipe developer Jennifer Meier specializes in creating healthy and diet-specific recipes. Five cheeses (four blue cheeses and Cheddar) were used in this study. Y.

Blue cheeses may be soft and creamy or crumbly in texture, with a characteristically sharp, piquant flavour. Double-cream blue cheese is a category unto itself, with a later arrival on the blue cheese timeline in the late 20th century. If three classes are used: (1) Roquefort, (2) Cheddar, and (3) the remaining blue cheeses.

The output of PLS-DA consists in assigning each sample to one of the predefined categories that, in line with our general purpose of obtaining an array capable of making classifications between blue cheeses, was each one of the cheeses. The consistency of Blue cheese is at first brittle and crumbly, but becomes softer and spreadable as ripening advances. Blue cheese, any of several cheeses marbled with bluish or greenish veins of mold. For such purposes pH indicators offer advantages over other indicators since they are cheap and commercially available, and can be easily incorporated to support ensuring array scalability. Moreover the data set was also analyzed by PLS-DA. Most blue cheeses are made from cow’s milk, but Roquefort is made from the milk of the ewe. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Depending on the blue cheese, the texture and flavor vary from crumbly, weepy, salty, and sharp to softer, creamy, and mildly earthy. McSweeney, ... Patrick F.

Methyl ketones, especially 2-heptanone and 2-nonanone, and short-chained fatty acids, especially hexanoic and octanoic acids, contribute significantly to the typical flavor of blue mold cheese.

Blue cheeses made from ewe's milk are whiter than those made from cow's milk. This open texture is achieved by encouraging mechanical openings during manufacture (by not pressing the curds after molding) and by piercing the cheeses with needles (by hand or a special machine).

Blue cheeses get their typical appearance and flavor from growth of the blue mould Penicillium roqueforti. Blue cheese pairs exceptionally well with fruit and nuts, and it's an excellent addition to an assorted cheese board.
