Packaging/Interactions
Many processors are not fully aware of the implications in their choice of packaging materials. Incorrect choice of packaging materials for certain products often leads to undesirable interactions between the product and its packaging. What was "in spec" when it left the processing plant can be "out of spec" when received by the customer.
What are the consequences? Reduced shelf life, poor "off-the-shelf" product quality, compromised product safety, and premature or seemingly "unexplained" rancidity or spoilage. Off-odors and flavors can drastically impact sales in a very short amount of time.
