  6. The visual analog scales were 100mm in length. How pleasant, salty and bitter scales were anchored by “not at all” and “extremely” and the texture and taste scales were anchored by “dislike extremely” and “like extremely.” The satiety VAS was measured 30 minutes after commencement of test food. How hungry, satisfied, and thirsty scales were anchored by “not and all” and “extremely.” How much could you eat scale was anchored by “nothing” and “vast quantities”.
