Objective: The objective of these studies are to determine the shelf life of the foods for human consumption.

There are two general types of testing; real time and accelerated.

Ambient Room Temperature

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

Test Protocols:

Typically, 12 Month Shelf Life (Ambient Temperature and Relative Humidity) with a combination of some of the following tests performed. (Total Samples: 13)

Room temperature studies can be customized to meet client’s need, to speak with someone on customization please call the Food Laboratory at Midwest Laboratories at 402-334-7770.

Accelerated

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

Test Protocols:

Typically, 12 Week Accelerated Shelf Life with a combination of some of the following tests performed (Temperature: 40 deg C/Relative Humidity: 75%) Total Samples: 13
