The tofu hasn’t spoiled even after a week. Were any other additives used?
Accordion toggleSengmyongmul Tofu does not contain added preservatives.
As a delicate product, tofu typically spoils after being left at room temperature for several days, and during warmer seasons, it may spoil even before the expiration date if distribution conditions are poorly managed.Despite its sensitivity, Sengmyongmul Tofu can maintain a shelf life of up to six days without preservatives.
This is made possible by the use of sterile-grade drinking water (first-class groundwater), carefully selected and refined ingredients, hygienic production facilities, and heat treatment technology that minimizes the intrusion of microorganisms during manufacturing.However, if any of these conditions are not properly controlled, the tofu can spoil quickly.
Conversely, when all conditions are well maintained, the tofu may remain fresh even beyond the six-day shelf life. -

Why does the color of soy sauce darken over time?
Accordion toggleThe change in the color of soy sauce is a natural phenomenon, similar to aging, that occurs as fermentation and aging progress.
The browning of soy sauce occurs due to the formation of brown melanoidins, which result from a reaction between amino acids (derived from proteins) and sugars (derived from carbohydrates).This natural process causes the soy sauce to transition from a pale yellow to a slightly darker yellow that stimulates the palate, and eventually to a rich brown color.
To delay this browning, it is best to minimize air exposure and store the soy sauce in the refrigerator.Doing so not only helps suppress color change but also helps preserve various nutrients and beneficial components that contribute to health by maintaining a lower temperature over time.
