In a technical session held today at the
Institute of Food Technologists
(IFT) Annual Conference in Orlando, Florida, a panel of
researchers and industry specialists shared results from
several studies on the performance, taste, nutrition, and
supply benefits associated with
Dow AgroSciences' trans
fat-free, healthier cooking oils. Acting as a replacement
for partially hydrogenated (PH) oils study results point to
high oleic, low linolenic (HOLL) canola oil as the superior
performing product for applications ranging from use in
frying, baking, as a spray oil, and as an ingredient.
These new oils, produced from
Dow AgroSciences' specially bred NEXERA™ canola and sunflower
seeds, have high oxidative stability and are exemplary
alternatives to today's partially hydrogenated oils. Partially
hydrogenated oils are high in trans fats, which have been linked
to a significantly increased risk of heart disease. These new
oils, which have a unique combination of high oleic and low
linolenic fatty acid content, are defined as containing zero
trans fats and lower saturated fats, making them a healthier
choice for food processors, food service, and consumers.
The
American Heart
Association's (AHA) newly released Diet and Lifestyle
Recommendations for 2006, which replace guidelines previously
issued in 2000, prominently address two key areas for change.
Specifically, for fats, AHA lowers the goal from less than 10
percent to less than seven percent of calories from saturated
fat in the diet. They also call for less than one percent of
total calories coming from trans fat. In order to accomplish
this, they call upon the food industry and restaurants to assist
the general public in accomplishing these goals by using trans
fat-free and low saturated fat oils in food preparation,
processed foods, and baked goods.
"When formulating a healthier
shortening for use in baking applications, a HOLL canola/fully
saturated cottonseed blend performed better than conventional
commercial shortenings in a series of trials by providing
uniform grain, soft crumb, and good volume," said Frank
Orthoefer of FTO Food Technology LLC, referring to conclusions
in his baking study.
"It is a big step to take the
trans fat out of shortening, which is traditionally 20-30
percent trans," adds David Dzisiak, global business leader for
oils at Dow AgroSciences.
These healthier oils can
replace partially hydrogenated oils in many current applications
such as spray oils, frying and baking, and offers the right
oxidative stability for long-term shelf life without aftertaste
or interfering with the flavor of the food. Additionally, these
oils provide consistency, clean, light taste and texture.
"This new research confirms
that these new oils are commercially viable alternatives based
on their improved health profile, performance, taste, and cost.
These new canola and sunflower oils are available in commercial
quantities from major oil suppliers, and Dow AgroSciences
recently made a pledge to double the production of these oils,"
Dzisiak said.
Superior Taste
A consumer product study of 170
adults and 179 teenagers conducted by Jeffrey Gross Marketing
Research found that french fries prepared using the new Dow
AgroSciences canola oil were equally preferred to fries prepared
using today's commonly used frying oil, partially hydrogenated
soybean oil.
When compared to a new, trans
fat-free soybean oil, however, both the adults and teenagers
significantly preferred the taste of fries cooked in Dow
AgroSciences' new trans fat-free canola oil ... by a margin of
two to one.
Superior Performance
A study by the department of
chemistry and biochemistry at the University of Lethbridge in
Canada found that these new oils have more than a 50 percent
greater fry life when compared to other cooking oils, making
them cost-effective for the food industry to switch.
The study, led by Roman
Przybylski, PhD compared the fry life and performance of 10
cooking oils used to prepare three different foods (french
fries, chicken, and fish) in a restaurant-style rotation.
In the study, the new oils
outperformed current industry standards by extending life by
greater than 50 percent. The study measured the presence of
total polar material (TPM) formation to determine the oil
discard point. The research team used 24 percent TPM, which is a
recognized international analytical standard at which oil should
be discarded.
The Dow AgroSciences canola and
sunflower oils never reached the 24 percent TPM mark, even after
88 hours of frying over the course of 11 days. Partially
hydrogenated soybean oil, low linolenic soybean oil, low
linolenic canola oil, and liquid canola oil all passed the
discard point at day six after 48 hours of frying.
Superior Nutrition
In nutritional tests conducted
as part of the Lethbridge study, food prepared using the high
stability canola oil had the lowest combined level of trans fats
and saturated fats of any oil tested. Nutrition analysis
demonstrated that the foods fried in the Dow AgroSciences'
canola oil had 65 percent lower levels of combined trans fats
and saturated fats than the same foods fried in partially
hydrogenated oils.
Food processors, who attended
the session today, learned that "The best nutritional quality of
fried foods were obtained when HOLL canola oil was used as the
frying medium," said Przybylski.
