The Secret Behind Fairlife Protein Shakes' Shelf Stability

One might wonder what makes Fairlife protein shakes unique compared to other milk products. What sets Fairlife protein shakes apart is the innovative combination of ultra-pasteurization and aseptic packaging.

This duo of technologies guarantees product stability and removes the necessity for refrigeration prior to opening – a boon for health enthusiasts always on the move.

Ultra-Pasteurization Process

Ultra-pasteurization is revolutionizing the dairy industry. While traditional pasteurization heats milk to 161 degrees Fahrenheit for 15 seconds, ultra-pasteurization goes above and beyond.

The process heats milk to 280 degrees Fahrenheit for just two seconds. This high temperature effectively eliminates potentially harmful bacteria, making ultra-pasteurized milk safer and extending its shelf life.

Fairlife protein shakes are produced with ultra-pasteurized milk, which substantially lowers the risk of harmful bacteria. This means that they can be stored for an extended period without the need to be refrigerated, unlike regular milk.

The ultra-pasteurization process kills the bacteria found in traditional milk, making it possible to enjoy a longer shelf life without sacrificing taste or nutritional value.

Aseptic Packaging

Ultra-pasteurization, while vital for the safety and longevity of Fairlife protein shakes, is not the sole contributing factor. Aseptic packaging plays a pivotal role in maintaining these shakes’ shelf life by warding off contaminants and retaining vital nutrients.

This process involves filling and hermetically sealing food or other contents in sterile packaging materials, making it suitable for products like chocolate milk.

The combination of ultra-pasteurization and aseptic packaging provides Fairlife protein shakes with a longer shelf life compared to other milk products, making them a popular choice among milk sold in the market.

This offers the consumers the liberty to enjoy the taste and nutritional richness of real milk, free of concerns about spoilage or refrigeration before opening.

The Difference Between Fairlife Core Power and Nutrition Plan

Fairlife offers a variety of protein shakes. Two of the most popular are Core Power and Nutrition Plan. The main difference between the two lies in their storage requirements.

Core Power is shelf-stable and does not require refrigeration before opening, thanks to the ultra-pasteurization and aseptic packaging processes. On the other hand, Nutrition Plan must be refrigerated before opening, as it follows a different packaging method.

Irrespective of their diverse storage requirements, both Core Power and Nutrition Plan are derived from real milk, ensuring a wholesome supply of protein and nutrients.

Whether you choose the convenience of Core Power, the refrigerated option of Nutrition Plan, or even incorporating protein powder, Fairlife protein shakes are a tasty and nutritious choice for those looking to support their health goals.

Before consuming a Fairlife protein shake, evaluate its appearance, smell, and taste. If there’s a foul or sour odor, changes in appearance, or an unusual taste, it’s best to discard the shake. Proper storage can help maintain the quality of your shake, so be sure to follow the recommended guidelines for unopened and opened products.

Proper Storage Techniques for Fairlife Protein Shakes

Proper storage of your Fairlife protein shakes is key to maintaining their quality, taste, and nutritional value. Whether you have unopened Core Power or opened Nutrition Plan shakes, following proper storage techniques can help preserve the product’s integrity and prevent spoilage.
