RCM Flax™ (Real Cold Milled)

Heartland's RCM Flax™ is truly a cold milled product and process. The flax enters the RCM process at room temperature, is milled at room temperature and exits at room temperature. Furthermore, our proprietary milling method does not grind, crush or liberate oil like other processes, making our product very unique.

• RCM Flax™ has a non-refrigerated shelf life
  of greater than 20 months.

A recent study performed by a major university* indicated that 20-month-old RCM Flax™ had a peroxide value of .28. The Cereal and Grain Specialists have stated that a peroxide value of 1.0 is considered very good and that a peroxide level of .28 on 20 month old, non-refrigerated milled flax is exceptional.

The "Other" Milled Flax

There are 2 main reasons conventionally milled flax spoils or oxidizes so rapidly.

1. The conventional milling process creates increased temperatures. Several processors use "cold milled" to describe product but studied closely, their products almost always heat up during the milling or grinding process.

2. Conventional processing actually expels or liberates oil that coats the ground particles.

The high temperatures and oil coated particles alone or in combination produce a product that turns rancid or oxidizes in a relatively short period of time.
