Effect of artificial light on the lipid oxidation of whole, cooked Northern shrimp (Pandalus borealis) during frozen storage

•Illumination during frozen storage increased lipid oxidation of Northern shrimp.•Medium size shrimp had larger increases in PV than x-large shrimp.•There was a less clear pattern with respect to the effect of size for the volatile oxidation products.•The color changes were not correlated with decreases in free astaxanthin.•The content of α-tocopherol in Northern shrimp was not affected by frozen storage.
