Eliminating food waste − new advances in technology

SHORT: STORAGE AND PRESERVATION

One of the United Nations Sustainable Development Goals is to cut global food loss and waste by half, and new Japanese technologies are helping. DayBreak, a company in Tokyo, uses a special freezing technique to preserve fruit far longer than conventional freezers, while retaining the original flavor and nutrition. While a company in Nagasaki, Isle, took a different approach with their method for drying and processing vegetables into thin sheets to allow long-term storage of various food that otherwise would be discarded. These vegetable sheets are ideal as emergency food, and their versatility appeals to creative chefs. We’ll introduce today’s Japanese food technology which tries to provide solutions to the global food issues.

00:00 In 2015, the United Nations announced a range of sustainable development goals.

00:20 One of these calls for cutting global food loss and waste by half.

00:26 At present, the world wastes 1.3 billion tons of food every year.

00:34 In Japan, there are people looking to technology to provide solutions to this problem.

00:43 Kinoshita Masayuki was inspired by an experience on an overseas trip.

00:50 I saw all these kinds of fruit that had never been imported to Japan, and this was a hot

00:55 country where food spoils quickly.

00:58 It seemed like a huge waste and made me want to do something.

01:04 Kinoshita focused on a special freezing technology that could allow foods to be used instead

01:09 of discarded.

01:13 It's much faster and operates at lower temperatures than normal methods.

01:19 The inside of the freezer reaches minus 35 degrees Celsius.

01:24 Multiple fans constantly blow cold air over the fruit from every angle, ensuring they

01:29 freeze evenly.

01:31 This process takes only one-tenth of the time required by normal freezers.

01:40 Kinoshita has already begun using this technology to create frozen fruit from produce that otherwise

01:46 would go to waste.

01:51 Food frozen by this new method can be preserved for up to six months and lose none of its

01:55 original flavor and nutrition.

02:02 Just by eating these fruits, you're helping their producers and contributing to solving

02:06 the world's food problem.

02:11 Souda Keisuke believes the elimination of food waste is the key to saving the planet.

02:22 By 2050, world population will exceed 9 billion people, and we're already talking about a

02:27 coming food crisis.

02:29 That's why we're building up stocks of grain.

02:32 But you can't keep stocks of vegetables.

02:34 If we can find ways to preserve vegetables long term, it will be a huge boon for the

02:38 human race.

02:41 Souda's method transforms discarded vegetables into a completely different form, so they

02:46 can be stored for long periods.

02:50 Today's delivery is a load of daikon radishes, a vegetable widely used in Japanese kitchens.

02:58 After being chopped up and boiled, the daikon are mashed into a paste.

03:07 A special technology is then used to dry and process the paste into thin sheets.

03:16 Looking like sheets of paper, they're just 0.1 millimeters thick.

03:26 Souda makes his vegetable sheets from daikon, carrot, pumpkin, and tomato.

03:32 Although they look nothing like the original vegetables, they retain all their original

03:36 flavor.

03:39 The sheets can be used for wraps, or as an edible base for other ingredients.

03:46 You can even fold them origami style to make a container that you can also eat.

03:56 Souda's invention is ideal for emergency food supplies.

04:01 They can be stockpiled in shelters where they stay good for up to two years.

04:08 Vegetables normally go off quickly, even in the refrigerator.

04:11 These sheets weigh very little and stay edible for ages.

04:15 I think we'll be seeing a lot more of this kind of food in the future, once people realize

04:19 how it lets you store food safely almost anywhere.

04:24 Japanese technology and inventiveness are finding fresh ways to preserve food, helping

04:30 solve the world's food problems by reducing waste.
