M ± SD = mean ± SD. WLC = within 90% to 110% of labeled claim. FT = freeze-thaw. RF = refrigerated, N/A = not applicable. For FT samples, 30 d, 60 d, 90 d, and 180 d samples were stored in the frozen (FZ) condition, and then directly tested. “60 d + 30 d” and “90 d + 30 d” refer to samples that were stored in the FZ condition for 60 or 90 d respectively, and then in the RF condition for an additional 30 d.
