Probar Shelf Life by Product Type
The Probar company provides clear shelf life guidelines for its various products, which are typically stamped on the packaging. The duration depends on the specific ingredients and composition of each bar. Proper storage, which generally means keeping them in a cool, dry place away from direct sunlight, is essential to achieve the stated shelf life.
Typical Probar Shelf Life Breakdown:
- MEAL Bars: 12 months.
- PROTEIN Bars: 15 months.
- BOLT Energy Chews: 18 months.
- PEAK Performance Bars: 12 months.
- THINS Bars: 15 months.
- LIVE Bars: 10 months (requires refrigeration).
Can You Eat Probars After the 'Best By' Date?
Many consumers wonder about the safety of eating nutrition bars after the date printed on the package. The distinction between 'Best By' and 'Use By' is critical here. For most food products, the 'Best By' date indicates when the manufacturer believes the product is at its peak quality, not when it becomes unsafe. Probars are generally shelf-stable and should be safe to eat for some time after the 'Best By' date, provided there are no signs of spoilage.
However, eating an older bar does have some downsides. The bar's texture may become dry or hard, and the flavor can diminish. The oils and nuts in the bar can also go rancid over time, resulting in an off-taste. To determine if an expired bar is still good, perform a visual and odor inspection first. If the wrapper is intact and there are no strange smells or discoloration, it is likely safe to consume, though not at its peak quality.
The Science of Spoilage and Proper Storage
The primary factors that cause nutrition bars to degrade are exposure to air, moisture, and heat. The packaging is designed to prevent this by creating a sealed, low-oxygen environment. However, if the packaging is damaged, the shelf life is immediately compromised. The plant-based fats found in many Probars can oxidize over time, a process known as rancidification, which leads to the unpleasant, stale flavor often associated with old bars.
Proper storage is the best defense against this process. Storing your Probars in a cool, dry, and dark place is ideal. For example, a pantry or cupboard is preferable to a hot car or a sunlit window sill. Some reports from older social media conversations with the company even suggest that freezing Probars can extend their life indefinitely. While newer guidelines focus on standard shelf life, freezing is a valid option for long-term storage, though it might affect the texture upon thawing.
Comparison of Storage Methods for Probars
| Storage Method | Typical Shelf Life | Pros | Cons |
|---|---|---|---|
| Pantry (Cool, Dry) | According to label (10-18 months) | Maintains optimal taste and texture; Convenient; Requires no special equipment. | Limited by manufacturer's 'Best By' date; Quality may degrade slightly over time. |
| Refrigerator (LIVE Bars Only) | 10 months (LIVE) | Extends life slightly for certain types; Maintains optimal freshness and texture. | Requires consistent refrigeration; Not necessary for all Probar types. |
| Freezer | Indefinite | Maximizes longevity for long-term emergency storage; Stops all spoilage processes. | Can alter texture upon thawing; Requires adequate freezer space; Not suitable for immediate consumption. |
| Car / High Heat | Significantly Reduced | Convenient for immediate travel. | Accelerates rancidity and spoilage; Drastically shortens shelf life; Not recommended for long-term storage. |
Maximizing Freshness and Preventing Waste
To ensure you always have fresh Probars on hand, follow a First-In, First-Out (FIFO) system for your food storage. When you purchase new bars, place them behind your older ones so you consume the oldest stock first. For large quantities, consider freezing some to preserve their freshness for later use, especially if you find a good bulk deal. Always check the packaging for any damage before consumption. If the packaging is torn, punctured, or otherwise compromised, it’s best to discard the bar, regardless of the date, as moisture and bacteria could have been introduced.
Conclusion
The shelf life of Probars varies by product, typically lasting between 10 and 18 months, with the 'Best By' date serving as a quality indicator rather than a strict safety deadline. While it is often safe to eat them past this date, the taste and texture may decline. For best results, store Probars in a cool, dry place. For long-term storage, freezing is an effective option, especially for bulk purchases. By understanding these factors, you can enjoy your Probars at their best and reduce food waste. Ultimately, rely on your senses of sight and smell to ensure the bar is safe and of acceptable quality before eating it.
