A Complete Moisture Analysis

Presented by

Brady Carter

About this talk

This seminar will highlight the importance of a complete moisture analysis consisting of both water activity and moisture content. Definitions for water activity and moisture content will be established with a particular focus on their differences. Methods for measuring water activity and moisture content as well as techniques for obtaining accurate measurements will be highlighted. The relationship between water activity and moisture content, referred to as a moisture sorption isotherm, will be described. Practical applications for water activity, moisture content, and moisture sorption isotherms will be detailed. These applications will cover both product safety and quality including: microbial safety, shelf life, ingredient mixing, temperature abuse, product formulation, caking and clumping, and package performance. 5 Major Learning Objectives: 1) What is water activity and moisture content? 2) How are water activity and moisture content different? 3) How are water activity and moisture content measured? 4) What is a moisture sorption isotherm? 5) How do water activity and moisture content influence product safety and quality? 6) How can the relationships between moisture content and water activity be used to improve product formulation?
