Jerky, a beloved snack known for its rich flavor and long shelf - life, has become a staple in many people's diets. As a supplier of oxygen absorbers for jerky, I've often been asked whether these little packets have an impact on the color of the jerky. In this blog, we'll explore the science behind oxygen absorbers and their potential effects on the color of jerky.
The Role of Oxygen in Food Preservation
Oxygen is a double - edged sword when it comes to food, especially jerky. On one hand, oxygen is essential for the growth of aerobic bacteria and fungi, which can cause spoilage and reduce the shelf - life of jerky. On the other hand, oxygen can also react with the components in jerky, leading to changes in its color, flavor, and nutritional value.
When jerky is exposed to oxygen, a process called oxidation occurs. Oxidation can cause the breakdown of pigments in the meat, such as myoglobin. Myoglobin is a protein that gives meat its red color. When it reacts with oxygen, it forms oxymyoglobin, which has a bright red color. Over time, further oxidation can convert oxymyoglobin into metmyoglobin, which has a brownish color. This color change is not only unappealing to consumers but also indicates a loss of freshness and potentially a decline in nutritional quality.
How Oxygen Absorbers Work
Oxygen absorbers are small packets that contain iron powder and other components. When exposed to air, the iron powder in the oxygen absorber reacts with oxygen through a process called rusting. This chemical reaction consumes oxygen, creating a low - oxygen environment inside the packaging.
The reaction can be simplified as follows:
4Fe + 3O₂ + 6H₂O → 4Fe(OH)₃
This reaction effectively removes oxygen from the packaging, preventing the growth of aerobic microorganisms and slowing down the oxidation process.
Do Oxygen Absorbers Affect the Color of Jerky?
In general, oxygen absorbers are designed to preserve the natural color of jerky rather than change it. By removing oxygen from the packaging, they prevent the oxidation of myoglobin and other pigments in the meat. As a result, the jerky is more likely to retain its original color for a longer period.
However, there are some factors that could potentially lead to color changes even when using oxygen absorbers.
1. Initial Quality of the Jerky
If the jerky has already undergone significant oxidation before packaging, the oxygen absorber may not be able to reverse the color change. For example, if the jerky has been stored in an oxygen - rich environment for an extended period, the myoglobin may have already been converted to metmyoglobin. In this case, the oxygen absorber can only prevent further color deterioration but not restore the original red color.
2. Packaging Conditions
The effectiveness of oxygen absorbers can be affected by the packaging conditions. If the packaging is not air - tight, oxygen can still enter the package, leading to oxidation and color changes. Additionally, if the packaging is exposed to high temperatures or humidity, it can accelerate the chemical reactions in the jerky and potentially cause color changes.
3. Type and Quantity of Oxygen Absorber
Using the wrong type or quantity of oxygen absorber can also have an impact. If the oxygen absorber is not powerful enough to remove all the oxygen in the package, oxidation may still occur. On the other hand, using an overly strong oxygen absorber may create an environment that is too low in oxygen, which could potentially affect the flavor and texture of the jerky, although this is less likely to directly cause color changes.
Benefits of Using Oxygen Absorbers for Jerky
Despite the potential factors that could affect color, the benefits of using oxygen absorbers for jerky far outweigh the risks.
1. Extended Shelf - Life
By removing oxygen, oxygen absorbers prevent the growth of aerobic bacteria and fungi, which can cause spoilage. This significantly extends the shelf - life of jerky, allowing it to be stored for longer periods without losing its quality.
2. Preservation of Flavor and Nutritional Value
In addition to color preservation, oxygen absorbers also help preserve the flavor and nutritional value of jerky. Oxidation can break down the fats and proteins in jerky, leading to off - flavors and a loss of nutrients. By preventing oxidation, oxygen absorbers keep the jerky tasting fresh and nutritious.
