Soy sauce packets are best used within one year of their production date, according to Kikkoman.
Kikkoman, a manufacturer of soy sauce packets, provides the following guidance on their product's shelf life:
- Best By Date: For optimal quality, it's recommended to use soy sauce packets within one year of their production date.
- Date Printing: Kikkoman started printing the "best by" date on the back of their packets in 2018.
Therefore, to determine how long your soy sauce packet is good for, check the back of the packet for a "best by" date if it was produced by Kikkoman after 2018. Using it within one year of production should ensure the best quality.
