Surprisingly all eight of the judges revealed that the appearance and the texture was just, but began to show differences with the flavor. Out of all the judges, six of them wrote that the flavor of the pasta was a little salty but could not distinguish the difference in the spinach being substituted for kale.
Discussion:
The difference in kale and spinach would be the nutritional values they provide in food; kale is considered a finer source of copper, calcium, manganese, and vitamin A, K, C, and B6. Spinach is richer in folate, iron, and fibre. They are both very healthy foods with nutritional similarities, but the texture of kale seems to be a little tougher than spinach. As a substitute, these foods are definitely interchangeable because during the experiment, the judges could not differentiate which was the control recipe and which was the experiment recipe.
