German researchers have found a smart way to turn food waste into a protein-packed food that tastes better than soy alternatives. Scientists at Justus Liebig University have used discarded carrot parts to grow a special fungus called mycelium. In tests, people liked these mushroom-based patties more than regular soy ones for their smell, taste, and feel. This could help solve big problems like hunger and climate change by making use of scraps that would otherwise go to waste.

The study came out on 16 December 2025 in the Journal of Agricultural and Food Chemistry. It shows how mycelium from pink oyster mushrooms, grown on carrot side streams, beats other plant proteins. Volunteers in blind taste tests picked the 100% mycelium patties over soy and even chickpea versions. This is big news as sales of plant-based meats drop worldwide, with many complaining about poor taste.

Turning Waste into Wonder Food

Lead researcher Martin Gand and his team tested 106 types of fungi on leftovers from orange and black carrot production. These scraps come from making natural colours and are usually thrown away. They picked Pleurotus djamor, or pink oyster mushroom, as the winner after checking which grew best and gave the most protein.

The team fine-tuned the growing setup to get top results. Mycelium grows fast, needs less time and space than full mushrooms, and makes proteins as good as those from plants or animals. The end product has less fat and fibre like other fungi. Gand said, “This study is a step towards a circular economy by transforming valuable food side streams into a high-quality protein source, highlighting the potential of fungal mycelium in addressing global food security and sustainability challenges.”

Funding came from the university and GNT, a company that makes natural colours from carrots. GNT wants to use 75% of its waste for human food by 2026. This teamwork shows how industry scraps can become tomorrow’s meals.

A Boost Against World Hunger

This discovery hits at the right time as hunger grows worldwide. UN reports say 733 million people went hungry in 2023 – one in every 11 persons. Another 2.33 billion faced moderate or severe food shortages. Gand added, “Utilising side streams as substrate for mycelium production reduces environmental impact while adding value and supports food security by enabling an efficient and sustainable protein production.”

Unlike soy or peas that need big farms and water, mycelium uses waste that is already there. It cuts down on new farming, which harms the planet with chemicals and deforestation. In places like India, where food waste is huge – millions of tonnes from veggies and fruits – this could mean local solutions. Imagine turning onion peels or potato scraps into inexpensive, tasty protein for the underprivileged.

Why Mycelium Could Change Everything

Fungi like mycelium are nature’s recyclers. They break down waste and build nutrients fast in controlled setups, like breweries or small factories. This means less land, water, and emissions than growing soy or raising animals. The German patties had protein levels matching meat, with a meaty bite that fooled tasters.

For India, this is exciting. Our veggie markets throw away tons daily. Firms like GNT show companies can partner with scientists to turn trash into cash. It fits PM Modi’s push for zero waste and Atmanirbhar Bharat – self-reliant food from our own scraps.

Experts say scaling up is key. Gand’s team calls for more trials to make mycelium patties cheap and widespread. As climate change hits farms harder, this fungal fix could feed billions without extra strain on earth.

In a world racing against hunger and waste, Germany’s mycelium breakthrough lights the way. It proves simple fungi from carrot peels can outdo fancy lab meats, bringing hope one patty at a time.
