4. Conclusions
The manufacture of cooked burger patties with vegetable oils as
replacers of pork-back-fat lead to products with enhanced nutritional
properties as a result of a more favorable fatty acid profile and higher
oxidative stability. In addition, the volatile components of burger
patties with added avocado and the olive oils indicate a more pleasant
aroma profile in these products. Whereas the avocado oil may impart
positive spicy and fruity flavor notes to burger patties, its impact on
other quality traits such as color and texture could be considered as a
noticeable drawback. The results from the present study highlight
remarkable technological applications of these vegetable oils as food
ingredients in the design of healthier meat commodities. The
accomplishment of further sensory analyses should confirm the
extent of the impact of back-fat replacement on particular sensory
features and on consumer's acceptance.
