Understanding food dating method
CARBON-14 IS CREATED (Figure 1a): When cosmic rays bombard the earth’s atmosphere, they produce neutrons.
These excited neutrons then collide with nitrogen atoms in the atmosphere, changing them into radioactive carbon-14 atoms.
According to federal regulations, open dating is not required except on infant formula (“Use-By” dates are mandated for these products).
Open dating on food products is the use of a calendar date to help determine how long a food is at its best quality.
They are manufacturer guidelines for when food is at its peak quality, a standard that is more concerned with taste and sales than consumer welfare.In contrast, radiocarbon forms continually today in the earth’s upper atmosphere.
