Fat replacement, Nutritional value, Olive oil, Pâté


The present study investigates the effects of olive oil when used as back fat replacers on the physico-chemical properties, fatty acids, cholesterol and α-tocopherol content of p.t.. The replacement of back fat by olive oil at 50 and 100% did not affect the moisture, fat or protein contents, while it increased yellowness. According to texture parameters, reformulated p.t. presented lower values for hardness, cohesiveness, gumminess and chewiness. The use of olive oil significantly (P < 0.05) affected the fatty acid content. The amount of MUFA increased, while the content of SFA and PUFA decreased as the back fat was replaced by olive oil. The replacement of fat resulted in an improvement in all nutritional indexes. Atherogenic and thrombogenic indexes decreased while the h/H ratio increased with fat replacement. At the same time, the content of α-tocopherol increased and the amount of cholesterol decreased with the addition of olive oil. Therefore, olive oil provides p.t. with high levels of C18:1n9c and MUFA, natural antioxidants such as α-tocopherol and reduces cholesterol levels. As a general conclusion, the replacement of back fat by olive oil allows us to obtain a healthier product.
