23 Aug 2024 --- Scientists at the Korea University in Seoul have examined four methods of extracting edible insect proteins from mealworms (Tenebrio molitor larvae) to overcome the challenges associated with conventional protein extraction methods, which they say are time-consuming, costly and energy-intensive. This comes as the F&B industry increasingly explores insect proteins as a more sustainable food source and regulations approving their use in foods. According to the FAO, this is due to the rising cost of animal protein, food insecurity, environmental pressures, population growth and rising demand for protein among the middle classes.
