Difference Between Some Organic, Conventional Produce


New research on specific sample groups shows some organic produce may have an added health benefit over conventionally grown counterparts, according to researchers presenting at the Institute of Food Technologists Annual Meeting and Food Expo. But inherent inconsistencies associated with organic farming make general comparisons inappropriate.

In her study of organic and conventionally grown tomatoes, Alyson Mitchell, a food chemist at University of California at Davis, found organic tomatoes had higher levels of secondary plant metabolites and higher levels of vitamin C.

“In looking at the (California) supermarket varieties of broccoli, we also found significantly higher levels of the flavonoids in organic broccoli,” said Mitchell.

As defense mechanisms in plants used to fend off infection and pests, metabolites in the body are thought to offer health benefits including reduced risk of heart attacks and coronary heart disease. Flavonoids are metabolites known to act in the body as antioxidants.

“It is recognized that high-intensity agricultural practices can disrupt the natural production of secondary metabolites involved in plant defense mechanisms,” Mitchell said.

No significant differences were seen between organic and conventional green peppers, Mitchell reported.

The findings add to a small body of literature showing higher levels of antioxidants in some organic produce, including research out of the UC-Davis showing higher levels of phenols in some berries.

Building solid evidence confirming the benefits of organic fruits and vegetables over conventionally grown produce is hampered by wide variances in organic farming, ranging from soil and climate differences to variations in crops, seasons and farmer philosophies, said Diane Barrett, also a researcher with the UC-Davis department of food science and technology.

“We need more controlled and real-life commercial studies, and we need better collaboration between researchers to get a broader look at growing systems,” said Barrett.

The IFT Annual Meeting and Food Expo is the world’s largest annual food science and ingredient conference, delivering comprehensive, cutting-edge research and opinion from food science-, technology-, marketing- and business-leaders. Now it’s 64th year, the IFT Annual Meeting and Food Expo registered more than 19,000 attendees and hosted nearly 1,000 exhibiting companies.

The convention concluded Friday.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
