MIT creates superhydrophobic coating for condiment bottles

Superhydrophobic_condiments-580x365When it comes to those last globs of ketchup inevitably stuck to every bottle of Heinz, most people either violently shake the container in hopes of eking out another drop or two, or perform the "secret" trick: smacking the "57" logo on the bottle’s neck. But not MIT PhD candidate Dave Smith. He and a team of mechanical engineers and nano-technologists at the Varanasi Research Group have been held up in an MIT lab for the last two months addressing this common dining problem.

The result? LiquiGlide, a "super slippery" coating made up of nontoxic materials that can be applied to all sorts of food packaging [MORE]

Packaging That Knows When Food Is Going Bad

110107083739 ScienceDaily (Jan. 7, 2011) — Packaging that alerts consumers to food which is starting to go bad is being developed by researchers at the University of Strathclyde in Glasgow.

The project aims to improve food safety and cut unnecessary food waste by developing a new type of indicator, made of 'intelligent plastics' which give a warning, by changing colour, of when food is about to lose its freshness because it has broken or damaged packaging, has exceeded its 'best before' date or has been poorly refrigerated.

Probing question: Is plastic dangerous?

Article36840 Sipping water from a bottle after a workout, microwaving a container of leftovers for lunch, giving the baby a bottle of milk: We use plastic every day, without even thinking about it. But numerous reports have suggested that exposure to bisphenol-A, an organic compound present in many food and beverage containers, could actually be damaging to our health. Is plastic dangerous?

Update June 2009 

Study shows BPA may leach from plastic bottles abstract

In a study published in Environmental Health Perspectives, Harvard School of Public Health researchers found that participants who drank for a week from polycarbonate bottles showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). The study, according to its authors, is the first to show that drinking from polycarbonate bottles increases the level of urinary BPA.

Latest from FDA - January 2010

FDA’s Update on Bisphenol A for Use in Food: January 2010

Bisphenol A (BPA) is an industrial chemical that has been present in many hard plastic bottles and metal-based food and beverage cans since the 1960s. FDA is taking reasonable steps to reduce human exposure to BPA in the food supply.  These steps include:

  • Supporting the industry’s actions to stop producing BPA-containing baby bottles and infant feeding cups for the U.S. market;
  • Facilitating the development of alternatives to BPA for the linings of infant formula cans; and
  • Aupporting efforts to replace BPA or minimize BPA levels in other food can linings.

FDA is supporting a shift to a more robust regulatory framework for oversight of BPA. In addition, the Agency is seeking further public comment and external input on the science surrounding BPA.

November 1, 2010. Bisphenol A (BPA) in U.S. Food. Enviromental Science and Technology. BPA was found in 63 of 105 sample food samples, including fresh turkey, canned green beans, and canned infant formula. However, levels were 1,000 times lower than the “tolerable daily intake” levels set by the U.S. Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA).

Solution, or Mess? A Milk Jug for a Green Earth

Milk.1.650 NORTH CANTON, The New York Times. Ohio June 30, 2008  — A simple change to the design of the gallon milk jug, adopted by Wal-Mart and Costco, seems made for the times. The jugs are cheaper to ship and better for the environment, the milk is fresher when it arrives in stores, and it costs less.

Amy Wise, of Ohio, said the gallon jug spilled milk everywhere.
