US 2006/0040040 A1 · Device for ozone treatment of plant materials

Abstract

The present invention relates to a novel process for the ozone treatment of unground plant materials such as wheat grains. According to the invention, this process consists in allowing the plant material to stand for at least one day after a prehumidification followed by an ozonization involving a complementary humidification that adds from 3 to 10% by weight of water, based on the dry weight of the plant material. This process is applied especially to wheat grains. In this case, a process according to the invention that enables the ozone to reach the core of the grains is carried out in order to manufacture so-called “technological” flours. The physical and chemical properties of such flours, observed as a function of the parameters of the ozonization process, are presented.

Dependent claims

A method for treating an unground plant material which comprises the steps of:

a) prehumidification of said plant material by the addition of a volume of water;
b) a rest phase for said humidified plant material;
and
c) exposure of said plant material to ozone,
wherein said rest phase has a duration greater than or equal to 1 day, and wherein the ozone treatment is carried out with a dry ozone-containing gas, said ozone treatment comprising a complementary humidification carried out simultaneously with, or at most 10 minutes before, said exposure to ozone under conditions that make it possible to add from 3 to 10% by weight of water to said plant material, based on the dry weight of the material.
