Hi all,
Our product is edible ice, customer had complained product pH out of spec.
For all information, our raw material is merely water only. So the pH content highly dependent many factors, such as temperature, and the way that lab handling our product during testing such as sample leave at room temperature to long , etc.
In such case, any idea how do we respond to customer, especially 'root cause' part. because this issue as if "beyond our control" it may reoccurrence in future.
