Why is my goat cheese blue? Uncover the fascinating secret behind this unexpected color transformation

Goat cheese, renowned for its distinct flavor and versatility, is a delectable delicacy enjoyed by many. However, encountering a blue tint in your goat cheese can raise concerns. This blog post delves into the reasons behind this discoloration, exploring the underlying causes and providing guidance on handling blue goat cheese.

Causes of Blue Mold on Goat Cheese:

1. Penicillium Roqueforti: The primary culprit behind blue mold on goat cheese is the fungus Penicillium roqueforti. This mold is intentionally introduced during the cheesemaking process to create the characteristic blue veins and pungent flavor of certain goat cheese varieties, such as Roquefort and Gorgonzola.
2. Contamination: In some cases, blue mold can develop on goat cheese due to unintended contamination. This can occur during production, storage, or handling, when the cheese comes into contact with airborne spores of Penicillium roqueforti or other mold species.
3. Aging: As goat cheese ages, it undergoes various biochemical changes. During extended aging, the cheese can develop blue mold as a result of the breakdown of fats and proteins by certain enzymes.

Is Blue Goat Cheese Safe to Eat?

The safety of blue goat cheese depends on the specific type of mold present. If the blue mold is a result of intentional inoculation with Penicillium roqueforti, it is generally considered safe to eat. However, if the cheese has been contaminated with other mold species, it may be unsafe for consumption and should be discarded.

Identifying Safe Blue Mold:

1. Appearance: Safe blue mold typically appears as evenly distributed blue-green veins throughout the cheese. It should not be accompanied by any other discoloration or foul odor.
2. Taste: Blue goat cheese with safe mold has a distinctive pungent flavor, which can range from mild to intense depending on the variety.

Handling Blue Goat Cheese:

1. Storage: Store blue goat cheese in the refrigerator at a temperature of 35-40°F (2-4°C). Wrap the cheese tightly in plastic wrap or place it in an airtight container to prevent further contamination.
2. Consumption: If you encounter blue mold on your goat cheese and are unsure about its safety, it is best to discard it. However, if you are confident that the mold is Penicillium roqueforti, you can cut away the moldy portions and consume the remaining cheese.

Preventing Blue Mold Contamination:

1. Proper Hygiene: Maintain strict hygiene during cheesemaking and handling to minimize the risk of contamination. Wash your hands thoroughly, sterilize equipment, and keep the production environment clean.
2. Temperature Control: Store goat cheese at proper refrigeration temperatures to inhibit mold growth.
3. Packaging: Use airtight packaging to prevent exposure to airborne mold spores.

The Bottom Line:

Understanding the causes of blue mold on goat cheese is crucial for ensuring its safety and enjoyment. If the blue mold is a result of intentional inoculation, it can be a desirable characteristic. However, unintended contamination with other mold species can pose health risks. By adhering to proper handling and storage techniques, you can minimize the risk of contamination and savor the unique flavors of blue goat cheese.
