Scientists from Oregon State University in the US have patented a nutrient-dense strain of red marine algae called dulse, which tastes remarkably like bacon when fried and contains 16% protein even when cooked. Dulse resembles a translucent red lettuce and is typically difficult to grow. However, this new strain is easily harvested.
According to a study by the California Academy of Sciences, the global population is expected to hit 9 billion by 2050. With this in mind, scientists are researching new ways to maximise abundant food sources, such as seaweed, and create new-format proteins that don't rely on cattle, livestock or fish supplies.
"We're seeing a fascinating array of sustainable food substitutes that could provide viable and tasty alternatives to diminishing foodstuffs," said Mandy Saven, head of Food, Beverage & Hospitality at Stylus. "If these can deliver on flavour and nutritional value as well as texture, I think they will become more widely accepted by food-savvy consumers. However, nobody will want an inferior offering."
Looking to other tasty food substitutes, American chef James Corwell has invented a sustainable tomato-based sushi that tastes like tuna, while Stanford University scientist Patrick Brown has created a vegetarian burger that 'bleeds' juices just like real meat, as discussed in Reframing Rare.
