How we tested spoilage

We stored our Sea Grapes Umibudo in the fridge at approximately 40°F (4°C) and held both opened and unopened samples for three days. During this period, we closely observed the samples for any signs of spoilage. On the third day, the opened Sea Grapes developed a slimy texture and emitted a strong odor, while the unopened ones appeared slightly less affected but still showed early signs of degradation. We conducted a quick cook test by heating a small portion to 165°F (74°C) to verify any changes, but ultimately, we discarded all samples that exhibited questionable characteristics, prioritizing safety above all.
