The chemical composition of garlic powder is represented by the same substances, only their amount per 100 g of product may differ. And in the 16th century, it was considered an inedible and even poisonous root crop. A depositional current, on the other hand, such as a turbidity current, is a mechanism of sediment transport within which the velocity, depositional rate, and grain concentration can change sufficiently to alter the depositional process through time. The percentage of starch in white potatoes has been shown to vary widely with the variety and many climatic and cultural conditions from as low as 9.6 in the Earlaine No. The main composition of the three elements are C x (H 2 O) y, where x and y are whole numbers and refer to certain carbohydrates.
