Data simulating zero-, first-, and simple second- and third-order kinetic reactions are employed at four elevated temperatures.The existence of a linear relationship is established between the logarithm of to.9 (the time required for the concentration of the reactant remaining to decompose to reach 90% of its original value) and the reciprocal of the corresponding temperature in absolute degrees.It’s important to understand what information the specific type of date code tells you about a food or drink. In general, there are two types of date codes: best-before dates and expiration dates.
The application of the linear relationship to predict the shelflife of dosage forms is discussed.
Keep in mind that you should always consult your community’s policies for specific information about food storage, safety and use, including day in and out recommendations.
Information about dates on pre-packaged food is a valuable source of information for consumers.
The most common terms are "best-before" dates, "packaged on" dates, and expiration dates.
Knowing what these terms mean will help you understand the labels, which in turn will help you make informed choices about the food you buy.
