1. A process for enhancing a food value of flax (Linum usitatissimum) seeds, comprising the following successive steps:
a) selecting raw flax seeds comprising the following successive steps of:
a1) providing raw flax seeds,
a2) measuring in each batch of said seeds a hydrocyanic acid content,
a fat content and an omega-3 fatty acid content and
a3) selecting only each batch of said seeds that has:
a content of cyanogenic compounds determined by an indirect method for assaying HCN after adding p-glucosidase according to the standard analysis method EN 16160 of April 2012 and corresponding to a hydrocyanic acid content (HCN content) of less than 250 mg per kilogram of raw flax seeds; and
a fat content greater than 38 g per 100 g of raw flax seeds and
an omega-3 fatty acid content higher than 20 g per 100 g of raw flax seeds and percent total fatty acids (TFAs) higher than 54;
b) mixing, where there are at least two raw materials of different nature and/or quality, and then fractionating, or fractionating and then mixing, said seeds from step a) to break the seeds coats and kernels;
c) impregnating the seeds from step b) with steam and/or a water-based liquid in order to reach on the seeds a temperature of 30 to 60° C. and a humidity of 10% to 60%, for 2 minutes to 8 hours;
d) pressurizing the seeds or mixture from step c) for 10 seconds to 2 minutes at a minimum pressure of 10 bars at a temperature of 80° C. to 160° C.; or d1) heating the seeds or mixture from or step c) for 15 minutes to 2 hours at a temperature of 80° C. to 150° C.
