Lineage Logistics is installing additional high pressure processing (HPP) machines and packaging equipment at its Allentown, Pennsylvania, and Mira Loma, California, units.

The company estimates that the installation of the machines, bought from Hiperbaric USA, is expected to be completed October.

Bay Grove, the parent company of Lineage, is investing in the expansion in order to meet consumer expectations of clean labels, preservation of product condition and extension of shelf life.

Lineage Logistics executive vice-president of sales and business development Tim Smith said: "We've been successful with HPP because it's a clean, natural, environment-friendly process for packaged foods that reduces the potential for spoilage and improves the quality of the product.

"We currently have customers using the solution for a variety of categories and expect demand for HPP to grow during the next several years."

The HPP is a post-packaging, non-thermal pasteurization method for killing pathogens, such as Listeria, E. Coli, and Salmonella via isostatic pressures up to 87,000 psi.

Hiperbaric USA director Jaime Nicolas-Correa said: "Lineage is an excellent partner for Hiperbaric in the US. They are the leading HPP evangelists and truly understand the positive impact the technology has for food and beverage manufacturers."
