Ever wonder why your cold-pressed juice at home lasts just a few days, while that ‘green juice’ on the grocery store shelf claims to stay fresh for a whopping two months? It might sound like magic, but the secret lies in a fascinating process called High-Pressure Processing (HPP). In this blog, we’ll dive into the world of shelf life mysteries, exploring how HPP processing is very different than RAW juice.
High-Pressure Processing (HPP) is a special method that helps juice stay fresh for a longer time. After making raw juice the juice is bottled in plastic bottles. These bottles are then placed into a big chamber filled with water, where they get pressurized up to 85,000 PSI (pressure units). The pressure increases the temperature of the juice, lasts for a short time, (usually a minute or so) and then it’s released.
After the bottles go through the process, the juice inside them doesn’t have tiny microbes anymore, and it extends the shelf for 30-45 days. This is much longer than raw juice, which usually lasts only 3-5 days. The big advantages are that the juice stores can keep it around for a more extended period without it going bad. According to FDA rules, juice that’s sold in the supermarket or any wholesale store needs to go through a process like HPP or heat pasteurization.
However, if your local juice shop sells directly to consumers, they can skip this step, which means the juice is a raw, whole food with ENZYMES.
Enzymes are like little helpers in our bodies that support various bodily functions. When juice undergoes pasteurization or HPP, the high heat or pressure can affect these enzymes. By avoiding these processes, more of the natural enzymes in the raw juice remain intact. These enzymes contribute to the digestion and absorption of nutrients, making the juice not only tasty but also potentially more beneficial for your overall well-being. So, opting for juices that skip pasteurization or HPP might be a great choice for those who want to enjoy the full health benefits of fresh and enzyme-rich beverages.
I often advise my clients to opt for the real deal when investing in a green juice—go for the benefits of RAW green juice rather than the processed alternatives. Be your own health advocate when buying your green juice and understand the distinction! You’ll get better value for your money by choosing a local organic juice bar over your neighborhood grocery store.
