Bee’s Pollen Moisture Determination by
Halogen Lamp Infrared Drying Method


Abstract:

This work describes the moisture analysis of bee’s pollen samples from tree different sources of Timiş county using the halogen drying, a new variation of infrared drying. Pollen is a complex bee product that contains sugar, aminoacids, lipids, water, minerals and that is heat sensitive. The determination of water content (or moisture) by drying method is therefore problematic, particularly when vigorous heating principles are used. To obtain the same results, as in the Karl Fischer method for water content (that was used as reference method), it is very important to chose adequate work conditions. This analysis is strongly influenced by the size of the pollen particle, the size of mass samples, time and speed drying. Keywords: bee’s pollen, moisture analysis, water analysis, halogen drying, Karl Fischer titration
