Retorted food pouches ready for market push

Knauss and Esskay introduce foods in retorted pouches without foil for retail. StarKist Seafood sells a foil-based pouch of tuna to foodservice accounts. Will others follow suit?

Along with products in #10 cans, fast-food outlets and sit-down restaurants can now order StarKist tuna in 2-lb, 11-oz retort po

Retorted pouches for food sold in both retail and foodservice environments could represent the next breakthrough in flexible packaging. In January, Quakertown, PA-based E.W. Knauss & Son introduced Knauss Creamed Chipped Beef in a stand-up retorted pouch. That offering is now competing with Esskay’s Creamed Chipped Beef (below left), also packed in a stand-up retort pouch. Esskay, part of Gwaltney of Smithfield, Ltd., Smithfield, VA, launched its product last year.

The two products are competing in Eastern U.S. supermarkets. Both are reportedly packed by the same contract packager, in the same pouch structure, and in the same 11-oz size.

These new pouches for food follow the April ’99 introduction by Kal Kan Foods of Whiskas Homestyle Favorites™ wet cat food (see Packaging World, Aug. ’99, p. 83, or packworld.com/go/whiskas). The Vernon, CA, company uses a laminated foil structure that helps provide a two-year shelf life for that retorted pouch-packed product.

Extended shelf life is a primary benefit when food is processed (sterilized) by heat and pressure in a retort chamber or vessel. Retort cooking of foods is usually done for rigid containers. The flatter profile of a flexible pouch allows it to be retorted in less time than is typically needed for cylindrical cans. Less time in a retort can mean less cooking for a firmer, less mushy product. For end users, the pouch is easy to handle, open and empty product to be reheated on the stovetop, or in some cases, a microwave.

Most retortable pouches incorporate foil into a multilayer structure to withstand the heat and pressure of the retort cooking chamber used to kill bacteria and provide the product inside with extended shelf life. But in the case of the two creamed chipped beef packs, no foil is used.

Instead, the strength and barrier properties are imparted by a 5 ?-mil structure that includes polyester/ink/proprietary adhesive/nylon/proprietary sealant. The polyester is reverse-printed by gravure in seven colors. The material is reportedly laminated, printed and fabricated into pouches by The Pyramid Group (La Habra, CA). That supplier says that the proprietary adhesive, polyester and nylon combine to provide an oxygen barrier. Empty pouches are shipped to a contract packager for filling and sealing.

Retail benefits

While neither Knauss nor Esskay would confirm packaging details, they did share some marketing insights about the new pouches. “It’s a brand new [package] for us,” says John Montmore, marketing manager at E.W. Knauss. The retorted pouch has a 90-day shelf life and replaces a nonretortable pouch. Curiously, that was an unprinted, stand-up pouch sold in a printed folding carton.

He says the graphics potential of a printed pouch swayed the company to select it. Of course, the change means that Knauss no longer has to purchase a carton for the product. The stand-up pouch, which Montmore says would be introduced in January, will retail for $2.99 at grocery stores in Baltimore, Washington, Philadelphia and New York markets.

Like its predecessor, the new version is sold in the refrigerated case. Based on our discussions with Esskay, Knauss and The Pyramid Group, shelf life of these pouches is longer if the pack is kept refrigerated. “In stores, we sell it next to packs of bacon and bologna in the refrigerated meat case,” says Montmore. That merchandising decision makes sense because that’s where consumers could find Knauss’s previous precooked creamed chip beef offering.

Montmore points out that Knauss also sells chipped beef by itself in a glass jar that consumers can use to make creamed chip beef at home. “But the current trend for busy consumers is toward convenient, prepared foods, and this package [targets] the home meal replacement market.”

The package serves the same marketing functions for Esskay. Representatives from both Esskay and Knauss whom we spoke with tell us their packs are sold in the refrigerated case and have a 90-day shelf life.

As this issue goes to press, Esskay has declined to discuss its package, other than to say it has proven popular so far in its Eastern U.S. retail markets.

Foodservice, too

StarKist Seafood, the Newport, KY, affilliate of H. J. Heinz, demonstrates that retortable pouches are also an option in foodservice applications. Last May, StarKist began selling a 2-lb, 11-oz flat pouch containing Albacore tuna to fast food outlets, including Subway and Blimpie’s. It’s also sold to sit-down restaurants who use the product in making tuna salad. The Albacore version followed the ’98 introduction of Chunk Light Tuna in the same size and package.

The Pyramid Group supplies both pouches, which provide an 18-month shelf life. StarKist would not divulge the material specifications, but did reveal that the pouches are packed at a StarKist facility in Ecuador on new Japanese sealing equipment, then retorted on a new FMC (Homer City, PA) retort system.

Measuring about 9”Wx12?”L, the pouches, “didn’t replace any other package,” says Michael Mullen, a company spokesperson. “They’re an alternative to a number 10 steel can that we use for four pounds of tuna.”

Mullen says StarKist added the pouch to meet customer requests. “In the foodservice market, they have to open a can and drain the broth out of the product before using it. The draining was an extra step for them,” he explains. “Our customers were asking for an alternative, so we developed this pouch, which allows the product to be used immediately.”

For Chunk Light Tuna, there’s no need for draining. For the Albacore Premium White Tuna, there’s minimal draining. “We need to add some moisture to the Albacore to protect it,” says Mullen. Pouches require less draining than cans, “because of the longer time in the retort that cans require,” he says. “To avoid scorching the tuna, we have to add more broth or water in a can than in a retorted pouch.”
