Biltong vs. Jerky: The Core Difference in Preparation
To understand the difference in protein content and overall nutritional value, it's essential to look at how biltong and jerky are made. The processing method is the primary driver of their divergent characteristics and nutritional outcomes.
Biltong, which originates from South Africa, is prepared by curing thick strips of meat in a blend of salt, vinegar, and spices like coriander and pepper. It is then hung to air-dry naturally at a low temperature, a process that can take several days or even weeks. This slow, low-heat method helps preserve the meat's natural nutrients, resulting in a more tender texture and richer, beefier flavor.
Jerky, on the other hand, is an American snack traditionally made from thin strips of lean meat. The meat is marinated in sauces that often contain sugars, soy sauce, or Worcestershire sauce, and is then dehydrated or cooked at higher temperatures (60–80°C). This heat-based process gives jerky its signature tough, chewy texture and can lead to some nutrient loss through protein denaturation. The inclusion of added sugars and preservatives can also impact its overall nutritional profile.
Protein Content: A Closer Look
When it comes to protein, the comparison isn't as simple as a single number. While both are protein-dense snacks, the method of preparation affects the final protein percentage and bioavailability.
Biltong Protein Content
- Higher Protein Density by Weight: Many sources suggest biltong has a higher protein content by weight, with some reporting averages between 50-60 grams per 100g serving. This is because the gentle air-drying process effectively removes moisture while concentrating the meat's nutrients.
- Better-Preserved Proteins: The low heat used in biltong production helps retain the meat's natural protein structure and amino acid profile, potentially making the protein more bioavailable.
- Low Carbohydrate Content: The absence of added sugars means biltong's protein isn't diluted by carbohydrates, making it a favorite for keto and low-carb diets.
Jerky Protein Content
- Variable Protein Levels: Jerky protein content can vary more widely between brands, depending on the cut of meat, fat content, and processing methods. A typical 1-ounce (28g) serving often contains 9–12g of protein, which translates to around 32–43g per 100g.
- Denatured Protein: The higher temperatures used to cook jerky can denature the protein. While this doesn't render it nutritionally worthless, it does alter the protein's structure.
- Added Sugars Affect Density: The marinades used for jerky often contain sugars, which contribute to the overall weight and carbohydrate count, effectively lowering the snack's protein density per serving compared to traditional biltong.
Comparing Fat and Other Nutrients
The differences don't stop at protein. Here’s a quick overview of other nutritional aspects.
- Fat Content: Biltong is often made with slightly fattier cuts of meat than jerky, and the air-drying process allows it to retain more fat. However, this is typically healthy fat that contributes to satiety. Many commercial jerkies are made from very lean cuts, but some may have higher fat content depending on the cut and processing.
- Sodium Content: Both are typically high in sodium due to the curing process. However, traditional biltong recipes often use less sodium than the marinades found in many commercial jerky products.
- Vitamins and Minerals: Because of the low-heat, air-drying method, biltong tends to preserve more of the meat's natural nutrients, such as iron, zinc, and B vitamins.
Conclusion
While both biltong and jerky are excellent high-protein snacks, biltong generally offers a higher protein content per serving due to its unique, low-heat air-drying process. This method not only concentrates the protein but also minimizes denaturation, preserving the meat's natural nutrients and resulting in a cleaner, less processed product. For those prioritizing a minimal-ingredient, high-protein, and low-sugar snack, biltong is often the better nutritional choice. However, for those who prefer a specific flavor or chewy texture, jerky remains a valid option, provided one checks the nutrition label for added sugars and sodium content. Ultimately, the best choice depends on individual taste preferences and dietary goals.
Biltong vs. Jerky: A Nutritional Comparison Table
| Feature | Biltong | Jerky |
|---|---|---|
| Origin | South Africa | United States |

| Typical Protein % (per 100g) | 50-60% | 32-43% |
| Processing Impact on Protein | Minimally affected; higher bioavailability due to low heat | Denatured by higher heat; may affect protein structure |
| Typical Sugar Content | Very low to zero (in traditional recipes) | Can be moderate to high due to added marinades |
| Texture | Tender, soft, and moist | Chewy and tough |
| Flavor | Natural, savory meat flavor with spice notes | Wide range of flavors, often sweet and smoky |
| Best For... | Keto, low-carb, and low-sugar diets | Variety of flavors and a tougher texture |
How to Make Your Own Protein-Packed Biltong
For those who want to maximize protein and control ingredients, making biltong at home is a rewarding process. While it requires patience, the result is a delicious, natural snack.
What You'll Need:
- Meat: A lean, high-quality cut of beef like silverside or top round.
- Spices: Coarse salt, ground black pepper, and coriander seeds.
- Preservative: Brown or cider vinegar.
- Equipment: A biltong box or a well-ventilated, cool space, and hooks for hanging the meat.
The Process:
- Prepare the Meat: Cut the meat along the grain into thick, even strips (approximately 1-inch thick). Trim off any excess silver skin or sinew.
- Cure the Meat: Generously coat the meat strips in a mix of vinegar and the spice blend. Ensure each piece is thoroughly covered.
- Marinate: Place the meat in a non-reactive dish, cover it, and refrigerate for 6 to 12 hours. This allows the vinegar and spices to penetrate the meat and start the curing process.
- Dry the Meat: Remove the meat from the marinade, pat it dry, and hang the strips inside a biltong box. The box should have a fan to circulate air and a light bulb to provide a constant, low heat source. This mimics the traditional South African air-drying process.
- Monitor: Allow the meat to dry for 4 to 7 days, or until it reaches your desired dryness and texture. The moisture content can be adjusted to create a softer, more tender snack or a drier, harder one.
- Slice and Enjoy: Once dried, slice the biltong thinly against the grain for maximum tenderness. Enjoy as a standalone snack or use it to add a protein boost to salads and other dishes.
This hands-on approach ensures you have complete control over the ingredients, sodium levels, and flavor, resulting in a healthier, higher-protein snack than many store-bought alternatives.
