Resveratrol: Not for Health but to preserve wine

Resveratrol: Not for Health but to preserve wine

Jan 06: Australia's Barokes Wines which claims that glass holds a number of drawbacks as a packaging medium for beverages – including its weight, durability and its “less than optimum” recycling ability has developed a process and applied for patenting it whereby beverage containers are coated with a layer including Resveratrol in order to better preserve wine

Metal cans, PET bottles and Tetra Pak cartons have grown in popularity in recent decades, but  their success with wine had been limited so far Barokes said, adding “This lack of success is primarily due to the relatively aggressive nature of wine – non-specific filling practices and non-specific lacquer specifications which are the cause of adverse wine integrity effects as a result of interaction between the product and container.”

Barokes points to the need for a fully recyclable integrated wine packaging system that allows global transit of the wine with no detriment to taste and a shelf life of over a year. “The traditional lacquers are applied to the inside of a beverage can for the purpose of holding a beverage in an aluminium container for a short period of between 3-6 months,” it adds. They do not  address shelf life stability and product integrity issues like flavor degradation, loss of freshness, changes in taste, aroma and color.

It is “generally recognized” in the industry that wine will lose its integrity in a can after six months, and the can manufacturers’ own internal guidelines accept this, says the application, according to the  report.

Barokes says their ‘surprising’ finding was that a partial internal coating layer including Resveratrol gave excellent protection against quality loss, preventing any reaction between beverages and packaging material.

Barokes Wines are the inventors of the innovative and patented wine packaging system which enables premium quality wine to be canned with stability and longevity. For details visit:
