Blue or bleu cheese has the mold Penicillium added to it, so that the final product is spotted or veined throughout with blue, blue-gray, or blue-green mold. The study was conducted on industrial batches of Penicillium roqueforti starters used in the production of the Gorgonzola cheese, with the aim to verify the production of secondary metabolites. Roqueforti & blue cheese. It is known for its transformative effects on cheese, but it also infects many other protein rich substrates and decomposes them. A. Abbas, A.D.W. Fig. Rennet is actually considered to be the main enzyme mixture involved in casein breakdown before P. roqueforti growth and during outgrowth (Hewedi and Fox, 1984). It is often relatively low in fat but has a high sodium content. C R C Critical Reviews in Food Science and Nutrition 1976, 8 (2) , 191-228. In some cases, these released molecules can positively contribute to flavor but also negatively via off-flavor production, such as bitterness, if not properly monitored and controlled. Cashews can be processed to be used to make Blue cheese using the Vegan Blue mold Penicillium Roqueforti PRB6 strain. Toxicities of PR toxin and roquefortine are low. Penicillium roqueforti growth is accompanied by the production of intracellular and extracellular enzymes for protein metabolism including an aspartic protease that hydrolyzes β-caseins and αS1-caseins, a metalloprotease with broad substrate specificity, an extracellular serine carboxypeptidase that releases acidic, basic and hydrophobic amino acids, and an extracellular metalloaminopeptidase that releases apolar amino acids not situated next to glycine residues (Grippon, 1993; Ardö, 2001; Cantor et al., 2004).

Contributing to fast growth rate, strong blue cheese flavor, blue-green color, and creamy consistency. This was totally unplanned but I am happy! Penicillium species such as P. notatum and P. rubrum were originally studied by Fleming in investigating the properties of the antibiotic penicillin. (2011) 19,402. Many P. roqueforti strains are known to be very tolerant to weak acid preservatives, being able to grow in the presence of 0.5% acetic acid and in the presence of 9000 ppm sorbate. In comparison to other cheeses, blue cheeses undergo extensive proteolysis contributing to distinct and characteristic blue cheese texture and flavor. It involves leaving a piece of sour dough bread with a pea sized piece of ripened blue cheese. As I said, blues aren’t my favourite cheeses, therefore I don’t make them often.

Leave the container opened for a few days allowing the bread to dry. Bullerman, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003, Penicillium roqueforti has been shown to produce several toxic compounds, including roquefortine, PR toxin, and festuclavine (Figure 14).

Penicillium roqueforti is used as a fungal starter culture for the production of a number of blue-veined cheeses, with both proteolytic and lipolytic enzymes produced by the fungus involved in cheese ripening and flavor production. In addition, blue cheese contains goat’s milk rather than cow’s milk, which is healthier in several ways. Molds are obligate aerobes and, therefore, require O2 for growth. Now I’m wondering what to do with the cheese if the blue doesn’t take.

A toxic factor in the fat of Roquefort cheese that caused severe injury to the liver and other organs of rats has been reported. Both mold- and bacterial-ripened cheeses are then ripened at 10–15 °C to promote microbial growth and activity, and at a high relative humidity to prevent loss of moisture from the cheese surface.

The low pH of freshly made cheese is therefore partially selective for the growth of yeasts and molds. The fungus also produces mycotoxins (fungal toxins) that give blue cheese its extraordinary taste, and sometimes make your mouth numb! Penicillium roqueforti strains isolated from Blue cheeses are known to produce both the mycotoxins PR toxin (7-acetoxy-5,6-epoxy-3,5,6,7,8,8a-hexahydrocarboxaldehyde) and roquefortine, which have also been shown to be present in cheese.
