Food Chemist Develops Protein-Based

Batter for Healthier Frying

January 1, 2006 — Deep-fried fish could get healthier with a new protein-based batter extracted from the muscle of discarded fish parts. When coated onto the fish it forms a barrier, locking in taste and moisture while blocking out fat.

GLOUCESTER, Mass.–Low-fat, fried food sounds like a contradiction, but those types of products may soon be popping up at your local grocer.

Fish sticks slathered in oil and deep-fried are tasty, but the after-effects can take a toll on your waistline. The love affair with food usually ends when it’s time to weigh in. Now, a new discovery may tip the scales in your favor when it comes to eating some of your favorite fried foods.

Stephen Kelleher, a food chemist at Proteus Industries in Gloucester, Mass., says, “People like fried food, but there’s a lot of bad things associated with fried food.” Understanding the bittersweet fondness for fried cuisine, Kelleher invented a way to cook low-fat, fried food.

The protein solution is extracted from fish muscle. When coated onto the fish it forms a barrier, locking in taste and moisture, but blocking out fat and carbohydrates. “These protein molecules after we treat them and extract them the way we do, they form these very, very, micro-thin films that — when they are sprayed onto the surface — become this invisible, impenetrable, film that forms on the surface,” Kelleher says.

The protein molecules go through a treatment process. Water and other ingredients are filtered then added to the batter. Kelleher says the finished product has 25-percent to 75-percent less fat. Plus the added protein cuts down the carbohydrates by 15 percent.

When put to the test, comparing traditional fried batter to the special protein coating, both food tasters agreed there was nothing fishy about the low-fat, fried meal.

The process is FDA approved and can be used to fry low-fat chicken, too. They are also testing the application on other foods, like potato chips.

Latin Name: Hoodia gordonii
Other Names: hoodia, xhooba, !khoba, Ghaap, hoodia cactus, South African desert cactus

Hoodia (pronounced HOO-dee-ah) is a cactus-like plant that grows primarily in the semi-deserts of South Africa, Botswana, Namibia, and Angola.

In the last few years, hoodia has been heavily marketed for weight loss and has become immensely popular.

Although there has always been a demand for diet pills, after the ban on the herb ephedra, the market was particularly ripe for the next new diet pill.

Much of hoodia’s popularity stems from claims that the San Bushmen of the Kalahari desert relied on hoodia for thousands of years to ward off hunger and thirst during long hunting trips. They were said to have cut off the stem and eat the bitter-tasting plant.

Hoodia gordonii grows in clumps of green upright stems. Although it is often called a cactus because it resembles one, hoodia is actually a succulent plant.

It takes about five years before hoodia gordonii’s pale purple flowers appear and the plant can be harvested.

There are over 13 types of hoodia. The only active ingredient identified so far is a steroidal glycoside that has been called “p57″. Currently, only hoodia gordonii is thought to contain p57.

What is the History of Hoodia Gordonii?

In 1937, a Dutch anthropologist studying the San Bushmen noted that they used hoodia gordonii to suppress appetite. In 1963, scientists at the Council for Scientific and Industrial Research (CSIR), South Africa’s national laboratory, began studying hoodia. They claimed that lab animals lost weight after they were given hoodia gordonii.

The South African scientists, working with a British company named Phytopharm, isolated what they believed to be an active ingredient in hoodia gordonii, a steroidal glycoside, which they named p57. After obtaining a patent in 1995, they licensed p57 to Phytopharm. Phytopharm has spent more than $20 million on hoodia research.

Eventually pharmaceutical giant Pfizer learned about hoodia and expressed interest in developing a hoodia drug. In 1998, Phytopharm sub-licensed the rights to develop p57 to Pfizer for $21 million. Pfizer returned the rights to hoodia to Phytopharm, who is now working with Unilever.

Much of the hype about hoodia started after 60 Minutes correspondent Leslie Stahl and crew traveled to Africa to try hoodia. They hired a local Bushman to go with them into the desert and track down some hoodia. Stahl ate it, describing it as “cucumbery in texture, but not bad.” She reported that she lost the desire to eat or drink the entire day. She also said she didn’t experience any immediate side effects, such as indigestion or heart palpitations.

Where is Hoodia Gordonii Found?

Hoodia gordonii is sold in capsule, powder, liquid, or tea form in health food stores and on the Internet. Hoodia is also found in the popular diet pill Trimspa.

Despite its popularity, there are no published randomized controlled trials in humans to show hoodia is safe or effective in pill form.

One study published in the September 2004 issue of Brain Research found that injections of p57 into the appetite center of rat brains resulted in altered levels of ATP, an energy molecule that may affect hunger. The animals receiving the P57 injections also ate less than rats that received placebo injections. However, this was an animal study and injections in the brain are different from oral consumption, so it cannot be used to show that oral hoodia can suppress appetite in humans.

The manufacturer Phytopharm cites a clinical trial involving 18 human volunteers that found hoodia consumption reduced food intake by about 1000 calories per day compared to a placebo group. Although intriguing, the study wasn’t published or subjected to a peer-review process, so the quality of the study cannot be evaluated.

What are the Side Effects of Hoodia?

There are some potential side effects of hoodia that you should be aware of. What are Hoodia’s Side Effects and Safety Concerns?

How do I Know if it’s Pure Hoodia?

There are widespread reports of counterfeit hoodia products. Mike Adams of News Target, estimates that 80% of hoodia products are contaminated or counterfeit. It’s impossible to know if a hoodia product contains pure hoodia and the active ingredient, unless it has been tested by an independent laboratory.

After looking at hoodia buyer’s guides, hoodia ratings, and hoodia comparisons on the Internet, my advice is that you be very cautious. Most of these sites have been secretly created by companies selling hoodia. They explain why the hoodia in other products is inferior, even though there are no published reports showing that one is more effective. Q&A: How Do I Know if it’s Pure Hoodia or a Fake?

Can This Oil Control Your Appetite?
By Michael Roizen, M.D., and Mehmet Oz, M.D.

Can’t stop munching? Tear off a piece of chewy, whole-grain bread. Now dip it (we didn’t say drench it) in the best olive oil you can find. Savor every flavor you can find in the mixture. And consider your snack-fest done.

See, olive oil contains oleic acid, a monounsaturated fat that helps control your appetite. Upon reaching the small intestine, oleic acid triggers the production of oleoylethanolamide (OEA), another fatty substance. OEA then finds its way to nerve endings that carry a hunger-curbing message to the brain (one that goes something like, “Hey. Stop eating! You’re full!!”). You don’t need to wait for appetite-suppressing drugs using OEA to be created to lose waist and to squelch the munching that is making your clothes tighter than a corporate budget. Get a similar effect with these strategies:

Work off your appetite. Regular aerobic exercise may make you less hungry, not more.

Fire up your omelet. Adding a little red pepper to your morning egg whites could decrease the amount you eat later in the day.

Have a stick. People who chew on gum after lunch have fewer hunger pangs, fewer cravings for sweets and eat fewer afternoon snacks than people who don’t chew the stuff.

Sleep! If you don’t get enough Zs, you increase your appetite. Tired and hungry isn’t a pretty combo (ask any waitperson at an all-night diner). Next time you want to snack, see if you can hit the sack instead.
