Scrolling through social media the other night, I stumbled upon a question about the use of baking soda on beef to tenderize it. This piqued my interest, especially since I know it's a common technique in Chinese and Asian cooking called velveting, where cornstarch, egg white, and baking soda are used in marinades for meats.
The idea is straightforward: baking soda affects the pH level of meat, hindering protein bonds from forming tightly and thus keeping the meat from becoming tough. The bonds, when too strong, squeeze out moisture, making the meat less tender. Increasing the pH level with baking soda prevents these bonds from tightening too much.
To put this theory to the test, I decided to experiment with ground beef. I used equal amounts of meat—one pound each—from the same package, cooked them in identical pans, and seasoned one batch with a quarter teaspoon of baking soda. I let it sit for 15 minutes before sautéing both batches under the same conditions to observe the effects. I was eager to see which would brown better and retain more moisture.
The results were quite astonishing. The batch of beef treated with baking soda retained 25 to 30 percent more moisture compared to the one without. It also browned more appealingly. In the baking soda-free batch, the released moisture was darker, suggesting that the Maillard browning, which lends the meat its rich flavor, was washed away because of the excess moisture escape. The experiment clearly showed the impact of baking soda on moisture retention and browning.
A common curiosity was whether there was a taste difference between the two. Given the small quantity of baking soda used and the nature of ground beef, there wasn't a noticeable flavor difference. I've tasted beef treated with more baking soda before which made it somewhat slippery and unpleasant, but this wasn't the case here. It’s generally advisable to rinse off baking soda in dishes using strips of meat to avoid off-putting flavors. In this case, however, the subtle amount didn't make a perceivable difference in taste.
One notable outcome was the tenderness of the beef with baking soda. While it might sound unusual for ground beef, the treated meat was indeed more tender. It was a fascinating exploration—watching the cooking chemistry at work, illustrating how a seemingly simple ingredient can significantly alter texture and moisture level of meat.
