Product Description

Oryzatein® (oh-RAHYZ-uh-teen) is the first patented allergen-friendly protein source from the whole rice grain, available in 80% and 90% protein levels. Providing all essential amino acids, this product is being used in food grade products as both a replacement for and in conjunction with soy protein and whey protein. It can also be blended with VegoteinPea Protein which has a complimentary amino acid profile to achieve a complete protein.

Sourced from exclusive crops across Asia, Oryzatein® Original is manufactured in a state-of-the-art facility which can double capacity year over year. Produced by means of an all-natural, proprietary process, patented Oryzatein is a coarse grade, beige (light to medium), free-flowing powder with an ideally bland to sweet taste. Oryzatein is a nutritionally beneficial source of plant-based protein along with essential minerals like iron, magnesium and phosphorous.

The Oryzatein® Rice Protein Difference

Constantly Working to Provide the Most Natural & Healthiest Ingredients Possible Research. Innovate. Test. Improve. Repeat. That’s how we did it in 2005 and how we still do it today.

Axiom relies on research and innovation to create new and better ways of creating healthful, plant-based ingredients. That started with extracting protein from all layers of the whole grain rice, including bran, germ and endosperm, in a low-heat, hexane-free process and continues today with the creation of the first suspension-grade rice proteins.

Along the way all the rice and resulting proteins are tested again and again, from and gluten-free certification to testing for meeting Prop 65 standards.  In order to meet these strict standards, the Axiom team works to improve our processes through more research, innovation and partnerships. For example, as a founding member of the World Rice Alliance, we are constantly working to source rice that is low in naturally-occurring heavy metals from multiple countries at once, as Axiom does from ideal areas of Thailand, China, Argentina, Vietnam, Cambodia and even California.

Not resting on laurels, Axiom is constantly setting new bars.  Axiom’s team has designed new proprietary processes utilized in Thailand and two other US manufacturing facilities, resulting in the first suspension-grade, grit-free rice protein.  In addition, multiple clinical trials are utilizing Axiom’s Oryzatein®, the most recent of which shows Oryzatein rice protein isolate is as beneficial as whey protein isolate at building muscles, decreasing fat mass and aiding exercise recovery, to becoming the USP monographed standard for rice protein.

Knowing that millions of people around the world purchase and consume nutrition-packed food, beverage and nutraceutical products with Axiom’s rice protein ingredients in them, the Axiom team takes the company mission very seriously, every hour of every day.

Hexane-Free Protein Extraction

hexane-freeWould you feel comfortable eating a product that was at some point doused in a volatile liquid known to be an atmospheric pollutant? Neither would we, and nor would we feel comfortable selling it either. Many plant protein manufacturers use hexane as their solvent during the extraction of edible oils and protein from vegetables or seeds, most notably soy and some rice proteins. Though, using hexane might be efficient, accurate and less expensive, Axiom Foods believes in producing quality ingredients without compromising sustainability, public and environmental health.

Hexane has not been established as a carcinogen to humans or animals, but the Environmental Protection Agency (EPA) has determined that acute exposure to hexane produces mild Central Nervous System depression, while chronic exposure results in polyneuropathy. Employees at food-processing plants incur the highest risk for exposure, but this does not leave consumers behind who are potentially exposed to residues in foods. The Food & Drug Administration (FDA) currently does not require testing of hexane levels in foods, nor does the FDA impose a ceiling on hexane residue in soy foods.

In addition to exposure risks, using this conventional hexane method poses other threats at local and global levels. On an environmental level, hexane is classified as a “hazardous air pollutant” due to its contribution to ground level ozone, which is the main component of smog. On a personal, employee level, although safety standards exist, hexane’s highly volatile nature can place facility workers in danger.

By choosing Axiom products, you can rest assured that no hexane nor any synthetic chemicals have been or will ever be used in the manufacturing of our ingredients. Our proprietary chemical-free extraction process uses enzymes to produce superior ingredients while providing safety for consumers, team members, and the planet!

Low Temperature Protein Extraction

Not only is our protein extraction hexane-free, but we understand the delicacy of working with proteins by manufacturing them using a proprietary low-heat process. To avoid protein denaturation, which can alter its chemical profile, Axiom Foods uses low temperatures which also prevents off flavors.

Not All Rice Protein is Hydrolyzed or Has MSG

Oryzatein is NOT hydrolyzed and does NOT contain monosodium glutamate (MSG)—and we have independent lab tests to prove it. This MSG myth evolved from conventional vegetable protein which is made from “junk” vegetables, typically unfit for sale and especially selected so as to have naturally high contents of “glutamate.” Hydrolysis is used to extract the protein fraction which involves boiling these vegetables in a vat of acid, followed by the process of neutralization with caustic soda. The resulting product is a brown sludge that collects on top. This is scraped off and allowed to dry. The end product is a brown powder that is high in MSG.

The controversy over this supposed nervous system stimulant continues to date, especially due to its ubiquitous presence in highly processed foods and its claimed relation to multiple health conditions. Despite this, the American College of Allergy, Asthma, and Immunology has concluded that MSG is not considered a food allergen and is a safe food ingredient. It is possible that a person might have a mild reaction to extremely large doses of MSG, but it is usually transient and benign. Additionally, the FDA has designated MSG as “safe to consume” while the World Health Organization (WHO) has placed MSG in the safest category for food additives.

Essentially, MSG is glutamate (an amino acid) that has been produced outside of the body (via acid hydrolysis), to which a mineral ion has been attached and usually accompanied by an array of by-products or impurities. Whether or not it produces negative effects upon consumption, Axiom Foods bypasses this possibility by proudly manufacturing non-hydrolyzed rice proteins.
