Liking rating data of 8 pigmeat products from 99 Australian females aged 25‐45 was analyzed using MDPREF. A line scale extended past the anchor points, 100 mm long and anchored by the words ‘dislike extremely’ and ‘like extremely’ was used. Liking was judged on the product name alone, no products were actually tasted. MDPREF configures products and consumers so that individual preferences (or product order preference) can be obtained. The order of product preference from the rating scores and order of product preference from the MDPREF analysis for each consumer was matched. It was found that the preference order for each consumer from the MDPREF map matched the order shown by rating scores in about 25% of cases. MDPREF produced 17% of consumers who had no products in the correct position for the preference order. Only 1% of consumers had all eight product preferences in the correct order.
