Maintaining shelf life for packaged coffee is a continuous challenge. The flavors and oils in coffee are oxygen sensitive, and the flavor profile is the primary value being delivered to the consumer. Oxidation, flavor degradation, and spoilage are all results of compromised package integrity. Leaks as small as 10 microns can draw O2 into the package over its shelf life. Coffee comes in a variety of package formats, but all coffee has one need in common, package integrity assurance for extended shelf life.
The coffee market is extremely competitive, with the flavor profile being the key differentiator for consumers. Whether the product is instant coffee, a brew capsule or ground coffee, the importance of package integrity is similar. Taking shortcuts in quality can cut deep into brand equity and profit. If a consumer encounters a product that exhibits oxidation, the bitterness and stale flavor will likely affect the consumer’s decision to repurchase.
While each package provides its own unique benefits, each format presents its own unique challenge to quality. This effective package integrity test method can provide accurate and sensitive feedback to assure a high level of quality.
