Selective UV light keeps beautiful, lush strawberries that way even longer  (Photo: Shutte...

A truism as old as strawberry picking is the observation that the juicier and tastier the strawberries, the more quickly the berries turn to a mushy heap of rot and mold, even in the fridge. An answer to longer fruit storage may come with research showing that selective UV light inhibits both decay and the growth of mold. With new LEDs able to produce specific types of UV light, we might see gadgets for use in the fridge that keep produce fresher longer.  Read More

FreshPaper is herb-infused paper, that is claimed to prolong the shelf life of fresh fruit...

While we all know how important it is to eat plenty of fruits and vegetables, it can often be difficult to use all that we buy before they spoil. A product known as FreshPaper, however, is claimed to keep such foods fresh two to four times longer than normal – and it does so just using spices.  Read More

Don't eat that fish - the blue color of the indicator film indicates that it's spoiled (Ph...

When it comes to buying packaged meat and fish, consumers usually just have to go by the “best before” label to know that it hasn’t begun to spoil. Needless to say, the dates on those labels are just estimates and certainly won’t tell you if the product has sat through a lengthy power failure, or been left out of the cooler for several hours. Researchers from the Fraunhofer Research Institution for Modular Solid State Technologies in Munich, however, have developed an inexpensive plastic film that will change color in the presence of rotten foods.  Read More

A new coating that reportedly allows foods to last longer has a structure similar to a bri...

We’ve already heard about new types of packaging that use things such as sorbic acid and silver nanoparticles to keep food fresh for longer, but this week scientists from Texas A&M University announced the development of a “nano-brick” film that utilizes yet another substance to achieve the same purpose. That substance is montmorillonite clay, which is one of the ingredients used to make bricks. The film is about 70 percent clay (with the rest of it made from various polymer materials) and when its structure is viewed through an electron microscope, it actually even looks like bricks and mortar.  Read More

Pull Ties are a new invention that offer a simple method of securely closing plastic bags ...

Scientists may be working on things like increasing the efficiency of solar cells, finding new methods of filtering water and growing hardier strains of wheat, but they have been woefully neglecting one important task for decades ... creating a better way of closing plastic bags. Currently, options include twist ties, spring-loaded clips, plastic tabs and zip-lock bags. The first three of those aren’t particularly sturdy, while it’s often difficult to get zip-locks to seal properly. Perhaps, however, all of us frustrated plastic-baggers might have better luck with the recently-released Pull Ties.  Read More

The deployment of MMP units in Darfur Refugee Camps has brought  clean water and power to ...

Recently we reported on Marines and their deployment of GREENS solar-power for technological devices on the battlefield. World Water and Solar Technologies (WWST) has also placed solar-powered water purification units throughout the world including war-torn Darfur, Sudan. Working with the Humanitarian International Services Group (HISG), two high-volume Mobile Max Pure (MMP) water filters have been installed that use the sun for their power. Placed in a carefully selected location where it could do the most good, each unit can generate up to 3.5kW of solar electric power and provide 30,000 gallons of clean drinking water for the many thousands of displaced civilians.  Read More

The Friis Coffee Savor canister with the special lid that vents CO2 gases which ruin good ...

Coffee-lovers of the world rejoice … a new coffee canister for the home that eliminates the four main causes of flavor loss in whole bean and ground coffee - CO2 gases, moisture, light and air - has been released by Friis. The company says its Coffee Savor container is the first in the world that vents away damaging trapped carbon dioxide gas created during the roasting process and also blocks out moisture, light and air to seal in flavor.  Read More

The Fresh shrinking milk jug

Milk goes sour in about a week, even if you keep it in the fridge. That's because Lactobacillus, the "good bacteria" that's found in yogurt, is constantly going about the job of oxidizing the lactose sugars in the milk into sour-tasting lactic acid - the same chemical that makes your muscles sore after exercise. But since this souring process requires the presence of oxygen, theoretically it could be slowed down even further if you kept the milk out of contact with oxygen. Rather than going with a high-tech nitrous contraption like the N2Wine globes we wrote about recently, one entrant to this year's James Dyson awards has come up with something devilishly simple: a shrinking milk jug that squeezes all the air out as you empty it. The inventor claims it lets milk last as much as a week longer. Simple and brilliant!  Read More
