What made the baby boomers great and all those that came to the U.S decades ago? Everyone worked hard; there were no handouts, today’s generations wants the best of the best, but they do not want to pay for it.When the going gets tough, many college students decide to take the easy way out and have no qualms about selling themselves to sugar daddies to pay for their college. Sounds like such a sad story, until you realise these spoilt brats want the best of the best for doing nothing. Simple Common Sense Fix Ends Student Debt Problem

Edible food packaging made from milk proteins

“The protein-based films are powerful oxygen blockers that help prevent food spoilage. When used in packaging, they could prevent food waste during distribution along the food chain,” says research leader Peggy Tomasula, D.Sc.

And spoiled food is just one issue. Current food packaging is mainly petroleum-based, which is not sustainable. It also does not degrade, creating tons of plastic waste that sits in landfills for years.

To create an all-around better packaging solution, Tomasula and colleagues at the U.S. Department of Agriculture are developing an environmentally friendly film made of the milk protein casein. These casein-based films are up to 500 times better than plastics at keeping oxygen away from food and, because they are derived from milk, are biodegradable, sustainable and edible. Some commercially available edible packaging varieties are already on the market, but these are made of starch, which is more porous and allows oxygen to seep through its microholes. The milk-based packaging, however, has smaller pores and can thus create a tighter network that keeps oxygen out.

“The coatings applications for this product are endless,” says Laetitia Bonnaillie, Ph.D., co-leader of the study. “We are currently testing applications such as single-serve, edible food wrappers. For instance, individually wrapped cheese sticks use a large proportion of plastic — we would like to fix that.” Full Story

Edible plastic food wrappers made from milk and fruit

The plastic film was presented by a US Department of Agriculture research team led by Peggy Tomasula at the 252nd National Meeting & Exposition of the American Chemical Society held in Philadelphia last week.

Tomasula and her team started by just using casein protein to form the plastic, but found it was too difficult to handle and easily degraded by water.

Citrus pectin, a type of polysaccharide extracted from citrus fruits, was added to strengthen it. They ended up with a plastic with smaller pores, so allowed less oxygen in than conventional plastics, making it a more effective preserver.

After a few modifications, the plastic looked similar to regular plastic but was less stretchy, a better oxygen blocker and completely edible.

The plan, now, is to apply this technology not just to new wrappings but coatings for food like cereal to keep its crunch instead of the sugar used today.

“The coatings applications for this product are endless,” says Laetitia Bonnaillie, who was involved with the work.

“We are currently testing applications such as single-serve, edible food wrappers. For instance, individually wrapped cheese sticks use a large proportion of plastic – we would like to fix that.”

Future plans also include the addition of vitamins, probiotics and dietary boosters which could eventually be incorporated into the plastic. Flavours could also be added. Full Story
