There is no difference between puffed soybean powder and puffed soybean. Puffed soybean, also referred to as puffed soybean, is generally made from imported soybean by whole crushing and refined by wet puffing. Expanded full-fat soybean powder retains the nutritional components of soybean and removes the anti-nutritional factors of soybean. It has high nutritional value, strong bean flavor, good palatability and high nutritional digestibility, and has been widely used in livestock and poultry and aquatic products.
