Sustainable, flavourful and healthy vacuum-dried products from food waste

Period: 2014 - 2020

The conversion of food waste into new valuable food ingredients and new products via energy-efficient vacuum-drying opens up the potential of a wide new market for the processing industries, and product developers and chefs.

Overproduction of food in highly developed countries is a reality, and consequently an increasing amount of environmental and economic resources are inefficiently utilised.

The high demand for fresh fruit and vegetable that meet the requirements for quality, freshness, shape and size causes overproduction.

About 110,000 tonnes of edible fruits and vegetables go to waste every year, which is approximately 33 percent of the produced amount of edible fruits and vegetables.

The food waste used as the basis for the present project is fit for human consumption.
