SCIENTISTS DEVELOPING 'SUPER SPAGHETTI'


Researchers at the University of Adelaide are collaborating with Italian researchers on two projects to investigate the fundamental role of cell walls in durum wheat and discover how they can be better utilized to produce better quality pasta with higher nutritional value.

The first project, in conjunction with the University of Bari, will investigate how the growth of durum wheat affects the levels of starch and dietary fiber within it, and how the fiber levels in pasta can be improved. The second project, in conjunction with the University of Molise, will investigate the important roles played by two major components of dietary fiber—arabinoxylans and beta-glucans—in the quality of pasta and bread dough.

"The term 'super spaghetti' is beginning to excite scientists, nutritionists and food manufacturers around the world," said Rachel Burton, associate professor and program leader at the ARC Centre of Excellence in Plant Cell Walls. “In simple terms, 'super spaghetti' means that it contains a range of potential health benefits for the consumer, such as reducing the risk of heart disease or colorectal cancer. Our research is aimed at achieving that, but we're also looking to improve the quality of pasta as well as its health properties."

According to the researchers, the new projects could help pasta manufacturers in South Australia and Italy to carve a niche by supplying domestic markets with specialist pasta products that will benefit the health of consumers.

STUDY SUGGESTS ENERGY DRINKS BOOST HEART FUNCTION


The effects of energy drinks on the heart have been hotly debated among the medical and regulatory communities; however, new research presented at the European Society of Cardiology (ESC) suggest consuming energy drinks can boost heart function.

Researchers from the University of Siena used speckle-tracking echocardiography, the avant-garde technique in echocardiography, and echo Doppler analysis to explore the influence of energy drinks on heart function. For the study 35 healthy subjects with a mean age 25 years drank a body surface area indexed amount of an energy drink (168 ml/m2) containing caffeine and taurine. Assessments of heart rate, blood pressure, left ventricular function and right ventricular function were undertaken at baseline and one hour after consumption. Heart rate increased by 1.2%, systolic blood pressure increased by 2.6% and diastolic blood pressure increased by 6%.

“This confirms that a standard energy drink consumption induces a light increase in diastolic blood pressure," the researchers said.

Left ventricular function improved in comparison to baseline. Right ventricular function was also improved one hour after consuming energy drinks.

“Taken together these results show that energy drinks enhance contractions of both the left and right ventricles, thereby delivering a positive effect on myocardial function," said Dr. Matteo Cameli from University of Siena. “This could be explained by the inotropic effect of taurine that, as previously demonstrated, stimulates the release of calcium from the sarcoplasmic reticulum."

He noted future studies need to focus on whether such benefits persist after long-term consumption of energy drinks, and what the effects are of consuming these drinks during physical activity.

ETHNIC SNACKING INSPIRATIONS


Snacking is a mainstay in street food and the bar and restaurant culture in various countries, making these little meals an opportunity to make cultural connections between people. Although a snack is sometimes a personal treat, in the case of a tradition like tapas, it’s often a ritualistic sharing of a few calories to bind trust and camaraderie among friends and family.

During my travels, snacking becomes critical to the success of my days. Out of professional (and personal) curiosity, I have an inherent desire to hunt for snacks and other foods throughout my host country, particularly since meal times on the road tend to be haphazard compared to my regimented schedule back home. I oftentimes find myself waning between meals, only to discover that dinner doesn’t start until 9 P.M.

Snacking through Latin America

Spain’s fertile landscape provides countless natural resources that all score high on the ethnic snacking scale. Consider the venerable mini sandwich known as the bocadillo, literally translated as “something small for the mouth," a small, snack-sized sandwich generally made with barra de pan (like a baguette). They are filled with everything from fruit marmalades to cheeses and thin-sliced meats, or even a small omelet. Various merchants, from high-end retailers to small, local markets and grocers, have little stands where the sandwiches are available. They are not nearly as large as our American sub sandwich, but rather intended as a true “tide me over" until dinner or the next impending meal.

Close cousins to bocadillos are Spanish pinchos or pintxos, originating in Spain’s Basque region and similar to tapas. These are generally small pieces of bread with olive spread, dry-cured meats, cheese, fish or roasted vegetables, presented on platters in a marketplace or bar. They are almost always served skewered with a toothpick so that the ingredients stay together. Pinxtos are considered more akin to finger foods than tapas, which tend to lean more toward knives and forks.

Snacking on tapas has already begun to take hold in the United States. These small, two- to four-bite plates are intended to be combined to create a larger, sharable meal, while single servings make a quick, flavorful snack. They are categorized as hot or cold, with types differing due to key ingredient influences in different regions. Spain’s coast is known for seafood tapas (like gambas al ajillo, garlic shrimp with pepper, chiles and/or paprika) and central regions for jamón ibérico (dry-cured ham, served simply on bread or by itself). Other areas might show some signs of French influence, such as the Basque region, where pinxtos, like bites of various cheeses, might be more common, or perhaps gildas, pickled, mild, green chiles skewered with anchovies.

My maternal heritage is deeply rooted in Chile, and—like Spain—Chilean culture has a propensity for snacking and socializing. In Chile, breakfast might be something light at home. Then, shared snacking enters the picture with something called las onces (“the elevens," referring to the time, although this break can sometimes come after lunch, around traditional “tea time"). Before and/or after lunch, there is a little time, usually a half hour, when areas like the town square fill with people seeking a little pastry and coffee, some freshly roasted nuts, fresh-picked berries, and small sandwiches.

Seasonality often plays a role in snack offerings, especially in Chile. Winter brings warm items, such as empanadas and roasted nuts (chestnuts, peanuts and almonds), to street-food snacking. Summer brings little bags of red murtilla berries (sometimes called Chilean guava), a tart-sweet, indigenous, high-antioxidant berry eaten fresh and often made into jam.

Empanadas de pino are often made with ground beef (seasoned with various mixes of cumin, oregano, garlic, paprika, salt and pepper), onions, raisins, black olives and hard-boiled eggs, all wrapped within slightly sweet dough and baked. The German immigration to Chile weighs in with the completo (“completed one"), which looks a bit like a Chicago-style hot dog, but often made with pickled vegetables (sauerkraut is common), chopped tomatoes, avocado and mayonnaise.

Let’s not forget the small bites and snacks of Mexico, which display various flavor influences from Spain, including the prolific use of corn and pork. Some notables are tacos al pastor, with rich flavors of dried and roasted chiles, slow-roasted pork, and corn. Sopes have a creamier version of a thick taco shell, hand-formed into a little pie shape and grilled, often served topped with roasted meats and cotija cheese, and perhaps some salsa. Crunchy, salty chicharones are pieces of pork skin that fry up completely devoid of moisture so the fat layers and solids in the skin puff up like crisped rice and deliver an amazing crunch, as well as rich, meaty—and sometimes spicy—flavor.

The streets of Asia

Asia is another snacking Mecca—from some of the very curious street foods of Vietnam, where juicy beetles are skewered and fried into crisp delicacies, to the sweet, salty Japanese combination of dried fish and toasted almonds.

Test Pesticides With Your iPhone

A good handful of months ago, I hesitantly swapped my trusted BlackBerry for an iPhone. Don’t get me wrong—I’ve been an Apple adherent for many years, and had already traded my costly PowerBook G4 laptop for an iPad without complaint, and have faithfully used Mac desktop computers since childhood (often alongside a PC supplied by work…).

Of course, I haven’t looked back and now wonder how I ever survived without the iPhone—and am continually amazed at its capabilities. Case in point, the other day, I ran across a Mashable story on a new device you can plug into your iPhone to test produce for potential pesticide residue (see “Lapka Turns Your Phone Into an Organic Monitor”).

Those of us who make the food industry our professional home know that, more than ever, transparency is key to establishing consumer trust. After all, folks are skeptical. And this Lapka iPhone device and app play right into that skepticism (other capabilities of the device include other paranoia-driven tests for electromagnetic fields and radioactivity, as well as humidity, with the latter option helping users determine their “perfect comfort level”).
The device basically seeks to detect nitrates in foods to, ostensibly, determine if they are truly organic or not (you can also test drinking water to discover pesticide contamination). Although it’s quite possible that the probe works on contact, I’m envisioning people carrying these devices around the grocery store and skewering fruits and vegetables—perhaps even poking through the barriers of packaged foods—with the probe before purchase, which I’m sure will rile many a store manager… Nevertheless, a cool idea that pushes the boundaries of iPhone capabilities.
