Additionally, the hurdle effect of food preservation, such as by adding lactic acid bacteria and salt to a food product, is illustrated and described. [11] [12] [13] This figure illustrates the pathway of food preservation followed by lactic acid bacteria involving nisin, as well as the pathway of food preservation followed by salt ...
A food storage calculator can be used to help determine how much of these staple foods a person would need to store in order to sustain life for one full year.
