Which dishes should not contain MSG? MSG is a common kitchen seasoning, and many know excessive consumption can be harmful. So, how can MSG be used healthily? Below are five types of dishes that should not contain MSG, helping you use it correctly.Meat naturally contains glutamic acid. When heated with salt in dishes, it naturally produces monosodium glutamate—MSG's main component. Beyond meat, other umami-rich foods like eggs, mushrooms, water chestnuts, and seafood also don't require added MSG.
Dishes containing vinegar should not have MSG added. Dishes with pronounced acidity or significant vinegar content should not include MSG. This is because MSG dissolves poorly in acidic environments; the higher the acidity, the lower the solubility and the weaker the umami effect. Thus, dishes like sweet and sour pork or vinegar-braised cabbage, which are highly acidic, should not have MSG added.
Avoid adding MSG to cold salads. MSG fully enhances umami only at temperatures between 80°C and 100°C. Since cold dishes remain below this range, MSG fails to activate and may even cling to ingredients, leaving them tasteless and disappointing. If MSG is essential for cold dishes, dissolve a small amount in hot water before mixing it in.
MSG should not be added to stuffing mixtures. Many people add MSG when preparing dumpling or spring roll fillings, which is unsafe. When mixed into stuffing, MSG undergoes high-temperature processes like steaming, boiling, or frying.However, MSG denatures at temperatures exceeding 100°C (212°F). Not only does it lose its savory flavor, but it also forms toxic sodium pyroglutamate, which can harm human health. Beyond avoiding stuffings, when preparing hot dishes, MSG should only be added just before removing the dish from heat.
Use MSG with savory, not sweet, dishes. Its savory flavor is most pronounced at appropriate sodium ion concentrations.Therefore, MSG's savory flavor shines best in salty dishes. Adding it to sweet dishes not only fails to enhance umami but also suppresses the natural sweetness and creates an off-flavor. Thus, dishes like Chicken Corn Soup or Sweet Taro Puree should never include MSG.
Precautions for Daily MSG Consumption
High-temperature usage. When cooking, adding MSG to extremely hot dishes triggers chemical reactions that convert it into sodium pyroglutamate. This not only fails to enhance flavor but also produces mild toxins harmful to human health.Scientific experiments confirm that MSG dissolves best at temperatures between 70°C and 90°C.
Therefore, the optimal time to add MSG is just before serving the dish. If thickening the sauce is required, add MSG before thickening. Based on the principle of avoiding high temperatures, you also need not add MSG when coating ingredients with batter.
Use at low temperatures. MSG dissolves poorly in cold conditions. For salads requiring MSG to enhance flavor, dissolve it in warm water, let it cool, then drizzle over the dish.In alkaline solutions, MSG undergoes a chemical reaction, producing disodium glutamate with an unpleasant odor. Therefore, avoid adding MSG when cooking alkaline foods. For example, squid treated with alkali should not be seasoned with MSG.
For acidic foods. MSG dissolves poorly in acidic dishes; the higher the acidity, the less it dissolves and the weaker its effect.
Finally, let's clarify the difference between MSG and chicken bouillon powder.
The Difference Between MSG and Chicken Bouillon Powder
MSG's primary component is monosodium glutamate, which imparts a savory flavor for seasoning but offers little nutritional value. Thus, MSG is essentially a pure flavor enhancer. Chicken bouillon powder, while containing a significant proportion of MSG, also includes various nutrients.High-quality chicken bouillon is made from fresh chicken meat, chicken bones, and fresh eggs as primary ingredients. It undergoes multiple processes like steaming, pressure reduction, and juice extraction, then blended with additives like MSG, sugar, salt, chicken powder, spices, and flavorings. Besides offering richer umami, chicken bouillon has far greater nutritional value than MSG and suits diverse culinary applications.
Consume MSG sparingly, as excessive intake can be harmful.
