Fairlife's Advanced Pasteurization Methods
Yes, fairlife Core Power is absolutely pasteurized. Fairlife uses advanced pasteurization techniques to ensure the safety and quality of its products. Unlike conventional milk, which typically undergoes High Temperature Short Time (HTST) pasteurization, fairlife utilizes Ultra High Temperature (UHT) methods. This involves heating the milk to a much higher temperature for a shorter duration. This powerful heat treatment is highly effective at destroying harmful pathogenic microorganisms.
This is why fairlife Core Power drinks, along with other 14oz fairlife products, can be shelf-stable and do not require refrigeration until opened. The pasteurization process is one half of the equation; the other is the specialized packaging that seals the product under aseptic conditions, preventing recontamination.
The Role of Ultra-Filtration
It's important to distinguish between pasteurization and ultra-filtration, as both are key to fairlife's unique product. While pasteurization ensures safety, the proprietary ultra-filtration process fundamentally changes the milk's nutritional composition.
This process involves moving milk through soft, permeable filters. These filters allow water, lactose, and some minerals to pass through, while concentrating the naturally occurring protein and calcium. The end result is a product with:
- 50% more protein than regular milk
- 50% less sugar than regular milk
- Naturally occurring lactose removed
Fairlife emphasizes that the protein content is naturally concentrated, with no additional protein powders or concentrates added.
Core Power vs. Core Power Elite: A Comparison
For athletes and fitness enthusiasts, fairlife offers a range of Core Power products with varying protein levels. The processing, including pasteurization and ultra-filtration, is consistent across the line, but the nutritional macros differ based on the product. Here is a comparison of two popular options:
| Feature | Core Power (e.g., 26g Chocolate) | Core Power Elite (e.g., 42g Vanilla) |
|---|---|---|
| Protein Content | 26g per bottle | 42g per bottle |
| Shelf Life (Unopened) | Up to 12 months | Up to 9 months |
| Primary Goal | Post-workout recovery | Maximize muscle recovery and building |
| Sugar Content | Low, with artificial sweeteners in some 14 fl oz bottles | Low, with artificial sweeteners |
| Added Protein | No protein powder added; protein is ultra-filtered | No protein powder added; protein is ultra-filtered |
| Calories | Approximately 170 kcal (Chocolate) | Approximately 230 kcal (Vanilla) |
Important Considerations for Consumers
While fairlife Core Power is safe for general consumption, there are a few important points for consumers to be aware of. The pasteurization and ultra-filtration processes are effective and regulated, but consumers should be mindful of other factors.
Potential Contaminants and Artificial Sweeteners
In recent years, Consumer Reports found elevated levels of phthalates, a plasticizer, in fairlife's Core Power High Protein Chocolate Milk Shake. While fairlife did not provide a comment on the study, it's a concern for some consumers. The presence of plasticizers has been linked to various health concerns, prompting some to limit their consumption of certain processed foods.
Additionally, some versions of Core Power, particularly the 14 fl oz bottles, use artificial sweeteners like sucralose and acesulfame potassium to maintain a low sugar profile. Individuals who prefer to avoid artificial sweeteners may need to check the ingredients list carefully. Some smaller bottle sizes in Canada have been noted to use real sugar instead of artificial sweeteners.
Storage and Shelf Life
Core Power is shelf-stable until opened, thanks to its UHT pasteurization and aseptic packaging. However, once the bottle is opened, it should be treated like regular milk. This means it must be refrigerated and consumed within 14 days to maintain freshness and safety. Always check the product packaging for up-to-date storage instructions.
Conclusion
In summary, fairlife Core Power is indeed a pasteurized product, utilizing advanced Ultra High Temperature (UHT) methods to ensure safety and provide an extended shelf life. This pasteurization works alongside the brand's proprietary ultra-filtration process, which concentrates protein and calcium while removing lactose. While the product is a safe and convenient option for post-workout recovery or a high-protein snack, consumers should be aware of potential issues raised by third-party testing, such as phthalates, as well as the use of artificial sweeteners in some variations. By understanding both the safety and nutritional aspects of fairlife's production, consumers can make informed choices about incorporating Core Power into their diet.
