Oryzan™ Rice Bran Oil: A Great Oil for Popcorn

Traditionally, coconut oil has been used as popping oil for making popcorn. It has good flavor and high stability. However, there have been concerns about the health effects of coconut oil used in popcorn, since 90% or more of it is saturated fat. Some alternative vegetable oils have been developed for popcorn use, such as soybean and canola oil. Even though these are low in saturated fat content, most of them are partially hydrogenated and contain trans fatty acids. Oryzan™ rice bran oil is a better oil for popcorn.

The RITO Partnership (Riceland Foods & Oilseeds International Ltd.) has been commercially extracting and refining edible oil from rice bran since 1994. Oryzan™ rice bran oil is extracted from the bran layers of rice. Because of its unique fatty acid composition, Oryzan™ does not have to be hydrogenated. In addition, rice bran oil inherently contains high levels of gamma oryzanol, a natural mixture of ferulic acid esters. Oryzan™ is processed by a non-conventional vegetable oil refining technique to retain much of the oryzanol naturally present in the crude oil. Due to its strong antioxidant properties, oryzanol retards oil degradation at elevated temperatures. This results in a high resistance to oxidation and cooked foods with improved storage stability. While Oryzan™ rice bran oil can be used alone, it can also be blended with other oils to improve their performance.

Popping Performance
Oryzan™ Rice Bran Oil Out Performs Coconut Oil and Partially Hydrogenated Soybean Oil

A study was conducted at Riceland's Research and Technical Center to compare corn popping performance of Oryzan™ rice bran oil with coconut oil and partially hydrogenated soybean oil. Our test data showed that the rice bran oil out-performed the coconut oil and the soybean oil in both popping performance and sensory quality. Oryzan™ rice bran oil is an all natural, stable, and great tasting popping oil.
