Can I eat blue cheese if I have an allergy to penicillin?
Blue cheese is made with cultures of Penicillium, giving it spots or veins of the mold throughout the cheese, which can vary in color through various shades of blue and green.There is a distinct smell from that or other specially cultivatedbacteria.Some blue cheeses are injected with spores before the curds form, and others have the same thing happen after they form.Blue cheeses are usually aged in a cave.Blue cheese can be eaten alone, spread, crumbled or melted into other foods.Blue cheese has a creamy texture.
The blue cheeses have a salty flavor.The smell of this food is due to both the mold and types ofbacteria encouraged to grow on the cheese, as well as foot odor and other human body odors.[5]
Blue cheese is thought to have been discovered by accident when cheeses were stored in natural temperatures and caves which were favorable environments for many types of harmless mold.The mold would form because it was moist in the cave.One of the first blue cheeses, Roquefort, was discovered when a young boy abandoned his meal in a cave after seeing a beautiful girl.He returned months later and the mold had turned his cheese into Roquefort.[6]
It is said that Gorgonzola did not have blue veins until around the 11th century.It became popular in the early 1700s.Many varieties of blue cheese, such as the 20th century Danablu and Cambozola, were an attempt to fill the demand for Roquefort-style cheeses that were prohibitive due to either cost or politics.There is a citation needed.
The process of making blue cheese is similar to other types of cheese.This blue-veined cheese requires additional ingredients and processes.Commercial scale production of blue cheese consists of two phases: culturing of suitable inocula and fermentation for maximum flavor.10
In the first phase of production, a Penicillium roqueforti inoculum is prepared prior to the actual production of blue cheese.Multiple methods can be used to achieve this.All methods use a freeze-dried Penicillium roqueforti culture.The commercially manufactured Penicillium roqueforti is used by cheese producers.Penicillium roqueforti is washed from a pure culture agar plants.Water from the frozen state is evaporated through the freeze drying process.The culture is retained and activated by the addition of water.
A sterile solution is used to add salt, sugar or both to milk.The mixture is inoculated with Penicillium roqueforti.The solution is put to use for three to four days.Aerobic incubation is continued for an additional one to two days after more salt and/or sugar is added.Pasteurized, homogenized milk and reconstituted non-fat solids can be mixed with sterile salt to create a ferment medium.A Penicillium roqueforti culture is added.A modified milk fat is added.The solution is prepared by the hydrolysis of the milk fat.Lipase action is necessary for rapid flavor development in blue cheese when modified milk fat is added.The inoculum is added to the cheese.[2]
The raw milk is mixed and Pasteurized at 72 C for 15 seconds.A starter culture, such as Streptococcus lactis, is added in order to change the acidity of the milk and turn it from liquid to solid.Rennet, a mixture of rennin and other material found in the stomach lining of a calf, is added to solidify the milk further.After this, thick curds are cut with a knife to encourage the release of liquid.The thicker and harder the cheese becomes, the smaller the curds are.There are no comments at this time.
The Penicillium roqueforti inoculum is sprinkled on top of the curds after they have been ladled into containers in order to be drained and formed into a full wheel of cheese.The cheese loaves are knit in molds and have a relatively open texture.For 10 to 48 hours, no pressure is applied, but the molds are inverted frequently to promote this process.Salt is added to provide flavor as well as to act as aPreservative so the cheese doesn't oxidize during the process of brine salting or dry Salting.The aging of the cheese is the final step.There is little to no blue cheese flavor development when the cheese is freshly made.Before the flavor of the cheese is acceptable for marketing, a 60–90 day ferment is needed.[2]
The temperature and humidity in the room where the cheese is aging is monitored to make sure it doesn't lose its flavor or texture.Depending on the type of blue cheese being produced, the ripening temperature is between eight and ten degrees Celsius with a relative humidity of 85%.The cheese loaves are punctured to allow air to enter and support the growth of the aerobic Penicillium roqueforti cultures.There are no comments at this time.
Throughout the ripening process, the total ketone content is constantly monitored as the distinctive flavor and aroma of blue cheese arises from the metabolism of Penicillium roqueforti.The blue cheese is sterile for four seconds at a temperature of 130 C.The heat treatment inactivates the Penicillium roqueforti.[2]
Several mycotoxins are produced by Penicillium roqueforti, which is responsible for the greenish blue moldy aspect of blue cheese.Penicillic acid and PR toxin are unstable in the cheese due to mycotoxins.Health risks due to Penicillium roquefortine are reduced because of the instability of PR toxin and lack of optimal environmental conditions.Large quantities of cheese are rarely eaten and mycotoxinContamination occurs at low levels, suggesting that hazard to human health is unlikely.[19]
The blue cheese is made from the casein.The casein in milk does not aggregate because of the outer layer, called the hairy layer.The micelles are prevented from spreading out because of the hairy layer between them.The rennet plays a role in removing the hairy layer in the casein micelle.When the hairy layer entangles, Rennet cleaves the -casein off the casein micelle.The casein micelles aggregate together when they collide, forming the blue cheese that can be made.
Oxygen is needed to grow Penicillium roqueforti.Lactic acidbacteria are used to make the cheese.The secondary fermenters, Penicillium roqueforti, take over and break down the lactic acid, keeping the aged cheese's pH above 6.0.As the pH rises again from the loss of lactic acid, the molds responsible for lipolysis and proteolysis are more active and can continue to ferment the cheese because they are optimal at a pH of 6.0.[22]
The blue veins in blue cheese are created by Penicillium roqueforti after the aged curds have been pierced.The mold can grow on the surface of the air interface.The blue cheese has veins that are responsible for the smell.The same type ofbacteria in blue cheese is responsible for foot and body odor.Studies show that blue cheese doesn't have the orange color that was thought to give it.The cheese is not tightly packed in order to allow for air gaps between them.The mold can grow in between the curds after piercing.
Lipolysis is the breakdown of fat.Blue cheese has a richer flavour and aroma due to the metabolism of the blue mold.[25]
In the European Union, many blue cheeses, such as Cabrales, Danablu, Gorgonzola, Roquefort and Blue Stilton, carry a protected designation of origin, meaning they can bear the name only if they have been made in a particular region.Individual countries have their own protections such as Italy's Denominazione di Origine Protetta.Blue cheese is simply "blue cheese".
