Intertek provides water activity (Aw) testing for food, grains and other agricultural products. Water activity is an important measurement property
for food testing. Water activity is used for compliance of government
regulations, CFR, HACCP and other food safety programs.

Application of Water Activity in Food testing:
Water activity measurement helps predict food stability
and food shelf life. Upper and lower level water activity measurements
help establish nutritional, texture, microbial, flavor, appearance,
aroma and cooking qualities for food products.
Controlling water activity helps to maintain the
chemical stability of food products. The condition and status of
water activity in food affects biodeterioration, spoilage, mold
growth, bacteria growth, chemical reactions and other food safety
and quality issues.
The USA food laboratory offers water activity
and water content testing. Water content analysis indicates total
moisture present in a food. Water activity analysis measures how
tightly moisture is chemically or structurally bound in food products.

Water Activity Laboratory:
The food laboratory uses state-of-the-art
laboratory instrumentation for water activity analysis, with accuracy
to ± 0.003 Aw in less than 5 minutes.
Food Testing to quality standards
The laboratory uses test methods such as AOCS, AOAC, USP, AACC,The
Food Chemical Codex, FTI, USDA, FDA and other recognized industry
and government standards. The lab participates in various
cross-check testing programs.
The Water Activity lab provides measurements to help predict food texture, bacteria, yeast and mold growth from microbes such as Pseudomonas, Escherichia, Proteus, Salmonella, C. botulinum, Candida, Micrococcus, micotoxigenic penicillia, aspergillus chevalieri, saccharomyces rouxii, monascus bisporus and many others. The food lab helps clients control and predict microbe activity.
