What To Know
- This type of nitrate is less common, but it is also used as a preservative in beef jerky.
- The amount of nitrate in beef jerky varies depending on the brand and manufacturing process.
- Beef jerky can be a good source of protein, but it is important to choose low-nitrate jerky and consume it in moderation.
Beef jerky is a popular snack known for its savory flavor and high protein content. However, concerns have been raised about the presence of nitrates in this dried meat product. In this blog post, we will explore the answer to the question: “Does beef jerky contain nitrates?”
The Role of Nitrates in Beef Jerky
Nitrates are chemical compounds that are commonly used as preservatives in food products. They help prevent the growth of bacteria and extend the shelf life of jerky. Nitrates also contribute to the characteristic pink color and savory flavor of beef jerky.
Types of Nitrates Used in Beef Jerky
There are two main types of nitrates used in beef jerky:
- Sodium nitrate (NaNO3): This is the most commonly used type of nitrate in beef jerky.
- Potassium nitrate (KNO3): This type of nitrate is less common, but it is also used as a preservative in beef jerky.
Are Nitrates Harmful?
In small amounts, nitrates are generally considered safe for consumption. However, excessive intake of nitrates can lead to health concerns, including:
- Methaemoglobinaemia: This is a condition in which nitrates convert hemoglobin in the blood into methemoglobin, which cannot carry oxygen effectively.
- Cancer: Some studies have linked high nitrate intake to an increased risk of certain types of cancer, such as colorectal cancer.
How Much Nitrate is in Beef Jerky?
The amount of nitrate in beef jerky varies depending on the brand and manufacturing process. According to the USDA, beef jerky can contain up to 200 parts per million (ppm) of nitrate.
How to Reduce Nitrate Intake from Beef Jerky
If you are concerned about nitrate intake from beef jerky, there are several steps you can take to reduce your exposure:
- Choose low-nitrate jerky: Look for beef jerky brands that have lower nitrate content.
- Limit your intake: Limit your consumption of beef jerky to moderate amounts.
- Drink plenty of water: Drinking water helps flush nitrates out of the body.
Other Preservatives Used in Beef Jerky
In addition to nitrates, other preservatives may be used in beef jerky, including:
- Sodium nitrite: This compound is similar to sodium nitrate and is also used to prevent bacterial growth.
- Sodium erythorbate: This antioxidant helps prevent the formation of nitrosamines, which are potentially harmful compounds that can form when nitrates are combined with certain amino acids.
- Citric acid: This natural acid helps lower the pH of beef jerky, making it less favorable for bacterial growth.
Final Thoughts
Beef jerky does contain nitrates, which are used as preservatives to extend shelf life and enhance flavor. While nitrates are generally considered safe in small amounts, excessive intake can lead to health concerns. By choosing low-nitrate jerky, limiting your intake, and drinking plenty of water, you can reduce your exposure to nitrates from this popular snack.
