Beef in Flavor or Flavor in Beef
On this early 4th of July morning while Tellïo completes the Murph Challenge, the smell of grilling and smokey notes drift into his nostrils. Many will light up their pits and grills. With that said, let's talk beef. In particular beef flavor. There are many factors that affect the taste and flavor of beef. The factors include:
Processing techniques & temperature
Duration
Composition of the animal
There is also a need to consider the interaction between several organic substances such as amino acids (building blocks of proteins), peptides (tiny pieces of proteins), lipids (fats & oils) and volatiles (chemicals with a strong smell). These substances are impacted by the animal species, food and processing techniques. Free amino acids such as glutamic acid and aspartic acid are found in mushrooms, tomatoes, seaweed and other sources. They improve the mouthfeel, the umami taste (meaty, savory taste), and balance the overall flavor. The nucleotides aka peptides Adenosine Monophosphate (AMP), Inosine Monophosphate (IMP) & Guanosine Monophosphate (GMP) contribute by heightening the intense of the salt, sour, spicy and other flavors associated with the meat. Organic acids like succinic acid and lactic acid enhance the umami taste, adjusting acidity, and delay food oxidation (prevents meat from turning brown or smelling unpleasant). The way meat is processed plays a vital role in its taste profile.
Processing methods consist of dry and wet aging, marinating, and smoking.
As part of the wet aging process, the meat is vacuum-sealed to prevent moisture loss, thus allowing proteolytic enzymes (natural proteins that act like scissors to cut up long proteins into smaller pieces) to break down muscle proteins into smaller, tasty fragments. As a result, there is a more subdued metallic flavor produced.
In contrast, dry aging is the process of storing meat at ambient temperatures and humidity without packaging. This permits sweat to evaporate, which concentrates the flavor and promotes microbial activity (think of bacteria, mold, and yeast as tiny workers that eat, thrive, and process the food). This gives beef a complex umami flavor that is nutty, earthy, and savory.
Marination is a common used approach that usually uses acids (such as vinegar, citrus), oils and spices. Acids breakdown proteins into delicate and succulent meat. While herbs and spices offer a complementary flavor.
Smoking is an established method that exposes meat to wood smoke and infuses it with phenols (flavor intensifier & flavour preserver), carbonyl (adds a rich, cooked taste and aroma) and organic acids (attribute a tangy, sour taste to food, help preserve it and affect texture). This yields aromatic and antibacterial characteristics. The cultivation of the animal influences the taste as well.
Tello opts for for the high cost grass-fed and finished beef for several reasons. He has long been suffering from stomach discomfort and symptoms resembling rheumatoid arthritis. Specifically around his knees when eating grain-fed beef. This could be the result of a higher ratio of omega-6s (too much can increase inflammation) to omega-3s (help to calm things down). In grass-fed animals, omega-3 fatty acids (cannot be produced by body, must be ingested) and conjugated linoleic acid (CLA) (healthy fat - key to energy, protection and balance) concentrations are elevated compared to grain-fed animals. From a taste perspective, omega-3 and CLA deliver a distinctive grassy and gamey flavor that's typically found in grass-fed meats. Meanwhile sweet and buttery flavor are more prominent in grain-fed meats.
Overall, it is interesting to see how meat can be prepared in a variety of ways, and how that affects the flavor in the end. It's really a preference thing at the end of the day, but the decision one makes can impact their health as well. In general be cognizant of what you consume, how it is processed and raised. As always Stay Strong & Stay Vivid!
