The combination of barriers is a fundamental concept in food preservation. It consists of the integrated use of different factors, both related to... food characteristicsas for production environment, to inhibit the growth of microorganisms and increase the shelf life of products.
In baking, understanding and correctly applying the combination of barriers is essential to ensure... quality, safety and durability of the loaves.
Next, you will understand what the main barriers used in the industry are and how to apply them efficiently.
pH of bread
O pH It is one of the most important factors in the microbiological control of bread. It directly influences the efficiency of preservatives and product stability.
Maintaining the pH at appropriate levels helps to hinder the growth of fungi and bacteria, as well as improving the action of the preservative ingredients added to the formulation.
Internal and external preservatives
Preservatives play an essential role in mold prevention and other types of contamination. They can be divided into two types:
- Internal preservatives: Added to the dough during preparation, they act against contamination from raw materials or failures in good manufacturing practices.
- External preservatives: When applied after baking, they protect the bread from contamination during cooling, packaging, and storage, stages in which the products are exposed to fungal spores suspended in the air.
The balanced use of these preservatives is one of the most effective ways to maintain the quality of bread for longer.
Good Manufacturing Practices (GMP)
As Good Manufacturing Practices (GMP), regulated by ANVISAThese are another essential pillar within the combination of barriers. They involve a set of measures that guarantee the safety and sanitary quality of food.
Some fundamental practices include:
- Keep machines, trays, and slicers clean and free of accumulated residue at all times;
- Sanitize floors, walls, ceilings, and all surfaces that come into contact with food;
- Separate the flour handling areas from the cooling and packaging areas.
Furthermore, it is essential that all employees are trained and qualified to follow hygiene protocols correctly.
Packaging conditions
Packaging is an extremely important physical barrier. Depending on the material used, the risk of contamination may be higher or lower.
Packaging more waterproof and resistant They offer greater protection against moisture, oxygen, and microorganisms, directly contributing to the preservation and quality of the bread.
Modified atmosphere
The use of modified atmosphere packaging is an increasingly common technique in the industry. bakeryThe process involves removing some of the oxygen from the packaging and replacing it with gases such as carbon dioxide (CO₂) e nitrogen (N₂).
This combination creates an internal environment that inhibits microbial growthSince most fungi and bacteria need oxygen to grow, carbon dioxide also acts as a natural antimicrobial agent, extending the shelf life of products.
Clean room
A cleanroom is a controlled environment designed to reduce the presence of particles and microorganisms in the air.
This type of installation is essential for the production of more sensitive food products, such as sliced and packaged bread, ensuring a lower risk of post-baking contamination.
Why combine Barriers?
The great advantage of combination of barriers That's because, when applied together, they create a the most complete and effective protection system.
Each barrier acts at a different point in the production process, from dough formulation to storage, and the sum of these factors results in... Safer, more stable, and longer-lasting bread.
In other words, the more barriers are integrated into the process, The longer the shelf life, the longer it will be. and the quality of the final product.
