Is there any evidence that meat did not spoil before the time of the Children of Israel, and is there any scientific research concerning the non-spoilage of food among the Pharaohs?

The meaning mentioned by the questioner regarding the hadith (definition): "Had it not been for the Children of Israel, food would not have spoiled, and meat would not have rotted," is one of two possible meanings for the hadith. The first is that the Children of Israel were punished by having food spoil after they hoarded the manna and quails, which they were forbidden from hoarding. The second meaning is that they established the practice of hoarding meat until it rotted, and had they not done so, stored meat would not have rotted. We cannot decisively affirm one meaning over the other without evidence from the Qur’an or Sunnah (definition). As for the scientific miracle in this hadith, no research has been conducted on it.
