Packaging With Natural Food Extract Vapor Inhibits Mold Growth

SoFresh, based in Wisconsin, USA, has developed a new technology solution that wraps food in an atmosphere of food-grade vapor inhibiting mold growth which can extend food distribution time, shelf life and consumption time, it says.

With over 2,500 species of airborne mold attacking food and turning it into waste, SoFresh explains it is able to manufacture a film container or covering that contains just the right amount of organic natural ingredients to enhance natural protection against mold growth.

The company discovered methods to infuse food-grade natural extracts into film or containers that emit controlled active vapor inside a food package. In a vapor state, these can reach the mold spores that do not touch the packaging surface. These spores absorb the vapor, which then slows down their metabolism to the point where it is difficult for them to thrive.

Since the vapor is derived from food extract it is safe for humans, according to the company. It has been tested successfully on many foods such as bread, cheese and berries and it imparts no new scents or flavors, tests confirm.

The film substrates are manufactured by combining inert polymers with natural plant extracts with only minor changes to standard film manufacturing methods. Company experts have worked with the FDA and independent laboratories to test and assure the safety of adding approved food extracts to the packaging materials.

There are numerous advantages to this technology, including reduction of logistics costs, increased reach of distribution, healthier ingredient and cleaner labeling, with ultimately a significant reduction in food waste, it says. The shelf life extension can be tailored to the type of food being packaged as well as the individual requirements of the food manufacturer – from hours to days.

This film technology is designed to not disturb the manufacturing or packaging process and does not require new capital expenditures since it is formulated to fit within the food producer’s current process, claims SoFresh.
