The Rise of High-Pressure Processing

Published on 17 Feb, 2023

High pressure processing (HPP) technology is witnessing rapid growth in the food and beverage industry. Consumer demand for fresh, minimally processed foods with longer shelf life; the need for safer and healthier food products; and the rise of HPP-processed functional foods are driving the HPP market.

HPP is a modern food preservation method that uses high hydrostatic pressure to extend the shelf life of perishable food products. The process subjects packaged food products to extremely high pressures (up to 600 MPa or 87,000 psi) using water or a water-based solution. HPP has been effective in eliminating a wide range of microorganisms, including bacteria, viruses, yeasts, and molds. HPP extends the shelf life of a variety of products, including fruit juices, deli meats, and seafood.

The global market for HPP foods is expected to expand significantly on increasing consumer demand for convenient, healthy, and minimally processed foods. According to a recent market research report, the global HPP foods market is expected to rise at a CAGR of 8.80% to US$ 5224.6 million during 2023–28.

North America, Europe, and Asia are expected to be the key markets for HPP foods, partly due to the growing number of health-conscious consumers in these regions. Increasing popularity of plant-based and organic products is also driving growth of this market.

The other drivers are:

Food safety: HPP is an effective method for inactivating a wide range of microorganisms in food, making it a useful tool to improve food safety.

Quality: The technology can extend the shelf life of perishable products, such as fruits and vegetables, without compromising their sensory or nutritional qualities.

Sustainability: HPP can help reduce food waste by extending the shelf life of products, which is a key concern in the food industry. Additionally, HPP is a non-thermal preservation method, which means it does not generate the same level of greenhouse gas emissions as thermal processing methods.

Consumer demand: There is increasing demand from consumers for minimally processed and "fresh” products. HPP can help provide this.

Technological advancements: The significant technological advancements in the field of HPP in recent years have made the process more efficient and cost-effective. This has increased its adoption in the food industry.
