What is HPP and Do I Need It?

What is HPP?

HPP stands for High Pressure Processing. I have heard other terms thrown around like High Pressure Pasteurization, and High Pressure Pascalization. In reality, Pascalization is the process of HPP, so the term High Pressure Pascalization is a bit redundant. Regardless of the specific words used, HPP is the process of putting tons of pressure on a substance to achieve microbial inactivation or to “alter the food attributes in order to achieve consumer-desired qualities” [Ohio State University]. HPP is done on juice that has already been pressed and bottled in plastic bottles. HPP does not work on glass bottles, because glass cannot withstand the force without breaking.

Do I need to HPP my juice before I sell it?

Under federal law, if you are going to sell juice wholesale (not direct to consumers), you need to process the juice in a way to meet the 5-log pathogen reduction performance standard. In laymen’s terms, you have to kill a bunch of the living stuff inside.  The law does not state that the method used to achieve the 5-log reduction has to be HPP. This can be done with a variety of ways such as heat, UV light, and HPP. Nobody’s into heat anymore, and UV light has some undesirable effects, and doesn’t work well on cloudy juices because the light has trouble penetrating the liquid.

If you are selling only direct to consumers, check with local health laws to determine if you legally have to process the raw juice.

I’ve been around juicing all my life. My Dad built his first hydraulic juice press in 1976 and founded the company Goodnature Products, Inc. I have incredible memories of having “cider parties” when we would invite all the people in our rural neighborhood over to make apple juice. To this day, when I taste apple juice made on a Goodnature press, a rush of nostalgia runs through my body.

I pride myself on guiding our clients into the world of cold-pressed juice and showing them how much fun this industry can be. I love talking business, technology, and marketing.
