OatiFresh Process

The Secret to Fresher Oats: OatiFresh™ Process

Throughout history, oats have provided us with nourishment, containing essential vitamins B1 (Thiamine), B2 (Riboflavin) & E, protein and minerals such as Phosphorus, Potassium, Manganese and Zinc amongst many others.

More recently, science has proven that oats contain more soluble fibre than any other grain, with one type of soluble fibre, beta-glucans, helping to lower cholesterol levels.

To ensure freshness, oat products by Captain Oats are kilned using our proprietary OatiFresh™ Process, a heat and moisture treatment to prevent them from going bad while retaining important nutrients. This means you get optimum goodness in every mouthful, every time.

Turning Oat Grains Into Edible Oats

Raw oats aren’t very good to eat so they go through certain processes to make them more palatable for us. The various stages include cleaning, dehulling, heating, sizing, cutting, flaking and lastly, packing.


Manufacturing Process

Oats harvested from the fields are first cleaned to remove dust, weeds, thin grains and loose hulls when they are brought into the Captain Oats’ milling plant.
The cleaned oat grains are sent for dehulling next. Here, centrifugal force sends the oats against an abrasive surface. The impact and abrasion causes oat hulls to be separated from their kernels or groats. Lighter hulls are separated from the denser groats via aspiration while scouring uses further abrasion to detach any adhering hulls and small hairs (trichomes). What remains afterwards are the denser kernels or groats.
Groats are high in fat. Once removed from their hulls and exposed to air, enzymatic activity begins to break down the layer of lipase or fat in groats. If they are not heated, groats will begin to show signs of rancidity within 4 days.

Heating helps stabilize and stop them from turning rancid for easy storage while also imparting groats with a delightfully robust, nutty flavor.

The dehulling process breaks whole groats into smaller pieces that have to be sized and separated for further processing. They’re fed to machines with sizing systems, where the groats are cut and sorted accordingly.
Once they’re sized, groats are flaked or rolled through 2 large rolls to ensure uniform thickness.  Before flaking, the groats are steamed to prevent them from breaking apart. The end result of the flaking process is oat flakes, also known as rolled oats.
Now that the oats are processed, it’s time they’re sent for packaging. From tins to plastic containers and softpacks, our oats are constantly monitored to ensure they meet the highest standards required by Captain Oats.
