  1. At what temperature will the test be performed?
    1. If samples will be sold refrigerated, then tests will be run using a refrigerator.
    2. If samples will be sold frozen, then tests will be run using a freezer .
    3. If samples will be stored at room temperature then there are two options (Real Time and Accelerated)
  2. How long would you like to run the study?

Refrigerator Shelf Life/ Freezer Shelf Life

Refrigerator shelf life studies have the ability to assess changes in food quality and microbiological growth This study will determine how long a sample will remain safe to consume while at refrigerated or freezer conditions. The frequency of the test is dependent on product.

Ambient, Room Temperature, Shelf Life

Room temperature studies have the ability to assess changes in appearance, odor, microbiological growth as well as rancidity.

Accelerated, 40 deg C/75% humidty, Shelf Life

Accelerated studies will assess changes in moisture content, water activity, and sensory characteristics. They can NOT be used to test for microbial growth
