I make homemade soy Labneh (AKA Greek yogurt) from soybeans by making soy milk, making yogurt from that milk and then straining out the liquids using a cheesecloth. The only ingredients are soybeans and the starter (probiotics or a previous batch of yogurt).
How would I go about finding approximate nutritional data for this yogurt, such as carbs, protein, fat, calcium etc? I googled but couldn't find any commercial Greek soy yogurt, only dairy ones.
