- High Pressure Processing
(HPP) is a method of food processing where food is subjected to elevated
pressures with or without the addition of heat, to achieve microbial
inactivation or to alter the food attributes in order to achieve
consumer-desired qualities.
- Pressure inactivates most
vegetative bacteria at pressures above 60,000 pounds per square inch.
HPP retains food quality, maintains natural freshness, and extends
microbiological shelf life. The process is also known as high
hydrostatic pressure processing (HHP) and ultra high-pressure processing
(UHP).
- High pressure processing
causes minimal changes in the fresh characteristics of foods by
eliminating thermal degradation. Compared to thermal processing, HPP
results in foods with fresher taste, and better appearance, texture and
nutrition.
- High pressure processing
can be conducted at ambient or refrigerated temperatures, thereby
eliminating thermally induced cooked off-flavors. The technology is
especially beneficial for heat-sensitive products.
- Most processed foods
today are heat treated to kill bacteria, which often diminishes product
quality. High pressure processing provides an alternative means of
killing bacteria that can cause spoilage or food-borne disease without a
loss of sensory quality or nutrients.
- HPP can be used to
process both liquid and solid foods. Foods with a high acid content are
particularly good candidates for HPP technology.
- At the moment, HPP is
being used in the United States, Europe, and Japan on a select variety
of high-value foods either to extend shelf life or to improve food
safety. Some products that are commercially produced using HPP are
cooked ready-to-eat meats, avocado products (guacamole), tomato salsa,
applesauce, orange juice, and oysters.
- In general, HPP can
provide shelf lives similar to thermal pasteurization. Pressure
pasteurization kills vegetative bacteria and, unless the product is
acidic, it requires refrigerated storage.
- High pressure equipment
design is a mature technology and has its origin in the chemical
processing industry. Most high-pressure vessels are manufactured under
guidelines established by the American Society of Mechanical Engineers
(ASME) boiler and pressure vessel codes.
- HPP does not present any
unique issues for food processors concerning regulatory matters or
labeling.
- High pressure processed
products are commercially available in the United States, European, and
Japanese retail markets.
