New Technology Could Be a Solution to Food Waste

Read Time: 4 188博金宝电子游戏

We don’t think too much about the food in our fridge, at least until it starts to go bad. Food waste — either because of spoilage in the home or because it doesn’t fit the ideal image we’re used to seeing in the grocery store — is a bigger problem than most people realize. Technology is shaping and changing the food and agriculture industry, and a new emerging piece of tech might be the solution to food waste in general. What is this new technology and how could it change how we think of food waste?

Beyond the “Use By” Date

Manufacturers stamp every piece of food you buy, except for fresh produce with a “best-by” or “use-by” date. This is a guideline that is often more important for stores selling to consumers. By law, grocery stores can’t sell foods past their use-by date. However, in some instances, it’s actually safe to consume for months after it goes out of date. However, it’s important to do your research first.

The date stamped on food packaging is a problem when it comes to food waste. Upwards of 40 percent of packaged food in the United States gets tossed in the garbage once it goes out of date, regardless of whether it has gone bad yet or not. of that, 35 million tons of food waste is dumped in U.S. landfills each year, putting a strain on the environment. While it can be a good rule of thumb for foods that can easily generate bacteria, like raw meats and eggs, many other items don’t spoil as soon as they pass their best-by dates. They simply pass their peak quality point.

Technology Might Have the Solution to Food Waste

Wouldn’t it be easier to tell if your meat had gone bad if there was a sensor on your package? That’s what one microbiologist from the University of Tasmania is trying to create. A simple sensor on the package, when viewed under a black light, shows whether the meat has been contaminated with E. coli. The sensor is simple, cheap to produce and could potentially be included on every perishable food item if it is approved for use by the FDA in the United States.

This isn’t the perfect solution — it won’t work on foods like canned goods or dry goods that aren’t prone to E. coli growth. These tend to go stale or lose their taste, but don’t generally become dangerous to eat once they pass peak freshness. These sensors ideally could reduce the confusion surrounding sell-by and use-by labels. These sensors are still in their infancy, but they show great potential to help reduce food waste and make perishable foods safer for consumers.

Problems With Transportation

Transportation is always a problem when it comes to the agricultural industry. People love their meat, fish and poultry, but these products aren’t always available from local sources, fresh from the farm or the ocean. Technology is changing the way we transport our food and making sure that even if it isn’t fresh from the farm, it’s fresh enough to enjoy safely. Much of this is due to the Internet of Things.

The Internet of Things, or IoT, includes a network level and a physical layer. More simply it involves an internet-connected device that communicates with other connected devices on a network. Your phone, cable box, computer and smart fridge are all part of the IoT. These connected devices can also ensure the freshness of food. Unfortunately, most food companies don’t choose to utilize this technology that could prevent food waste while saving the companies money and increasing customer satisfaction.

These devices could be as simple as connected thermometers that monitor the temperature of the food while it is being transported. If one or more of these thermometers drop below the required transportation temperature, an alert can be sent to the driver or the freight company to let them know that there is a problem, so there will be no wasted food.

Food waste is an enormous problem, especially when there are so many people around the globe who don’t have access to healthy food. Globally, more than $1 trillion worth of food is wasted every single year. In fact, first-world countries waste more food than is produced in all of sub-Saharan Africa in an entire year.

New Innovations

Technology is quickly changing and shaping the way we grow, transport and package food — and soon it might keep our food fresher while it is being transported. Hopefully, more transport and food packaging companies will start to adopt these new technologies as a solution to food waste. Not only will they save money, have happier customers and ensure food is fresher when it arrives, but it will also help reduce the epidemic of food waste that is gripping our planet.
