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.
