A recent study explored how incorporating extra-virgin olive oil (EVOO) into veggie patties and using different cooking methods affect their nutritional quality and sensory appeal. The research, conducted by Chilean scientists, found that patties enriched with EVOO and cooked via air frying or baking were significantly more nutritious and palatable than those that were deep-fried. These findings reinforce the dietary benefits of olive oil and suggest healthier ways to prepare plant-based dishes.
The Science Behind Healthier Veggie Patties
This comprehensive study was divided into two main phases. In the initial phase, researchers meticulously crafted veggie patties using a base of broccoli, carrots, onions, egg whites, oat flour, and a blend of seasonings including salt, pepper, garlic powder, and cumin. A crucial element of the experiment involved adding approximately half a teaspoon of extra-virgin olive oil (EVOO) to half of these patties during their preparation. These olive oil-enriched patties, along with their un-enriched counterparts, were then subjected to three distinct cooking methods: deep frying, air frying, and baking. The nutritional changes in the patties were rigorously measured by comparing the nutrient composition of the raw samples with that of each cooked patty, allowing for a precise assessment of nutrient gain or loss.
The second phase of the study focused on the human element: a blind taste test. Fifty-three participants, predominantly women (77%) with a significant portion (40%) being young adults aged 18 to 20, were recruited from a university campus. Each participant received samples of the various patties without any prior knowledge of their EVOO content or cooking method. They were asked to rate the sensory attributes of each sample, including taste, texture, aroma, and appearance, on a scale of one to seven. A score of one indicated a strong dislike, while a score of seven represented a strong preference. This dual-approach methodology ensured that both the scientific nutritional impact and the consumer's sensory experience were thoroughly evaluated.
This research offers valuable insights for everyday cooking and highlights the importance of choosing appropriate ingredients and cooking methods to maximize nutritional benefits. Olive oil, a cornerstone of the Mediterranean diet, is celebrated for its rich content of monounsaturated fats and antioxidants, known for their anti-inflammatory and disease-preventing properties. While past concerns about cooking with olive oil centered on its smoke point and potential nutrient degradation, more recent studies, including this one, suggest that these effects are minimal, especially when temperatures are maintained below 375°F. Therefore, embracing EVOO in cooking, whether for savory dishes like salad dressings, marinades, or even baked goods, can significantly enhance the nutritional profile of meals. Consumers are encouraged to select high-quality EVOO by looking for tinted bottles, recent harvest dates, and quality assurance seals to ensure they are getting the most beneficial product for their health and culinary endeavors.
