Analysis of Total Package Oxygen in Cans of Downeast Cider
PublicDownloadable Content
open in viewerThis project worked in collaboration with Downeast Cider House to analyze trends of total package oxygen (TPO) in cans of Downeast original blend hard cider. TPO values were calculated by directly measuring dissolved oxygen and using Henrys law to indirectly determine headspace oxygen. Statistical analysis showed that, of the ten fill heads in the packaging process, fill heads 2 and 5 produced significantly higher TPO values. Cans from fill heads 2 and 5 had average TPO values of 3.3 ± 0.8 ppm, while the remaining cans had average TPO values of 2.2 ± 1.0 ppm. Headspace volume did not vary significantly between fill heads or significantly impact TPO values. The composition of headspace, affected primarily by the nitrogen purge line in the packaging process, appeared to largely impact TPO.
