HPP stands for High Pressure Pasteurization and is a process for preserving food. Microorganisms (including probiotics) are inactivated in juices by means of high pressure (several thousand bars), whereby shelf lives of up to 3 months can be achieved. Cold pressed juices treated with HPP should therefore not be declared “fresh”. That’s why you need to ensure that the juices you buy at the supermarket or order home for a cleanse are really fresh.
Why WE don’t use HPP.
Since our establishment in 2009, we at PURE DELIGHT (formerly Detox Delight) have been of the opinion that a juice cure should benefit your health. The fresher and more untreated a juice is, the more nutritious and the better it is for our bodies. In the classic pasteurization process, the juice is heated and any added health value (vitamins, enzymes, etc.) is destroyed. And even if experts confirm that the nutrients are preserved in the more modern HPP treatment, the vitamin and nutrient content drops drastically after 5 days because most nutrients evaporate over time and do not survive prolonged storage. The longer a juice is stored, the lower its content of antioxidants, enzymes and vitamins. Anyone who resorts to a HPP-treated juice will in principle receive a deceptive package: Although the HPP juice may have been preserved in such a way that all its ingredients have been retained, nothing remains of them after weeks of storage in a cold store or on a refrigerated shelf. And yet one still pays high prices for HPP juices which no longer do any good.
What you need to know. With HPP, vitamins and nutrients cannot be preserved or even “trapped”. Although some companies promote HPP as the new modern miracle alternative to pasteurization, it remains undisputed that juice treated in this way is neither fresh nor rich in vitamins and nutrients like untreated juice after prolonged storage.
Why we have written this article?
Most people drink cold-pressed juices for the sake of their health and are often mistaken in the belief that all cold-pressed juices are the same. Although some (although not all) of the nutrients are initially retained in the HPP process, they cannot be “trapped” and degrade as quickly as untreated fresh juices.
When juices are consumed as part of a juice cleanse, fresh, completely untreated juice, which is drunk within 3-5 days of production at the latest, is the only sensible choice, as the desired cleanse effects are largely absent otherwise.
MYTH: If there’s no HPP on the label, there’s no HPP in it.
FACT: Neither juice cleanse suppliers nor traditional juice producers are required to specifically inform consumers that they are using HPP to preserve their juices. Accordingly, there is usually no reference to this in their websites. What you can assume: As a rule, 98% of all bottled juices available in retail stores, fitness studios or vending machines are HPP-treated. Even some juice bars use HPP. So you shouldn’t just assume that the cold-pressed juice you buy is automatically fresh. Better be on the safe side and find out whether your juice has been HPP-treated or even pasteurized by asking the supplier critically.
MYTH: When a juice is cold pressed, it is automatically fresh and untreated.
FACT: Just because a juice is cold-pressed doesn’t mean it’s fresh. Cold pressing is a process in which fruit and vegetables are juiced through hydraulic pressure in order to release more plant constituents, vitamins and enzymes from the fibers, which are also degraded less quickly by oxidation than in other pressing processes such as centrifugal juicing. Many juices are cold-pressed and then preserved using the HPP process or pasteurization, so that they can be sold for weeks or even months. We think that you can also save money for such juices, because they do not have the desired positive benefit for your health.
MYTH: If a juice is described as “raw” or “unpasteurized”, it is correspondingly fresh and untreated.
FACT: That CAN, but MUST not be the case. Companies using HPP may continue to label their juices as “raw” as the treatment took place without heat. They may therefore claim that the juice is not pasteurized.
MYTH: The label shows exactly how many vitamins are contained in the juice.
FACT: The vitamin content indicated on the label corresponds to that immediately after pressing. However, the nutrients begin to decrease drastically after only a few days. Therefore, after only a short time, the information on the label no longer reflects the actual vitamin and nutrient content in any way.
