Abstract

Absorbent Properties Research

This work has highlighted some very interesting features concerning the absorption properties of oilseed rape meal. The main findings are as follows:

Meal derived from low crucie acid, low glucosinolate meal, described as LEAR meal, will absorb approximately three times its own weight in water. At the point of saturation, however, the structural integrity of the meal is lost and it forms a porridge like consistency. The LEAR meal proved able to absorb around its own weight in oil and organic solvents. The structure of the meal remained unchanged at saturation, that is it retained its granular consistency.
