• Keywords: weijing, 味精, MSG in Chinese, what is weijing, monosodium glutamate Chinese, umami flavor, xianwei, Chinese cooking, Chinese restaurant syndrome, flavor enhancer, is MSG bad for you.
• Summary: 味精 (wèijīng) is the Chinese word for MSG (monosodium glutamate), a powerful and widely used flavor enhancer in Chinese cuisine. It is prized for its ability to add a savory, “umami” (鲜味, xiānwèi) taste to soups, stir-fries, and other dishes. While it is a staple in many kitchens, it has also been at the center of health controversies, particularly in the West under the name “Chinese Restaurant Syndrome.” This page provides a comprehensive guide to its meaning, cultural significance, and practical use in modern China.

• Pinyin (with tone marks): wèijīng
• Part of Speech: Noun
• HSK Level: HSK 5
• Concise Definition: Monosodium glutamate (MSG), a salt used as a flavor enhancer to create a savory taste.
• In a Nutshell: Think of 味精 (wèijīng) as a crystalline powder, like salt or sugar, that acts as a “flavor booster.” It doesn't have a strong taste on its own, but when added to food, it amplifies and deepens the existing savory flavors, creating the rich, satisfying taste known as “umami.” It's the secret ingredient that often makes restaurant food taste so addictively delicious.

• 味 (wèi): This character means “taste” or “flavor.” It is composed of the radical 口 (kǒu), meaning “mouth,” and the phonetic component 未 (wèi). It directly relates to the sensation of flavor experienced by the mouth.
• 精 (jīng): This character means “essence,” “refined,” “spirit,” or “the best of.” It contains the rice radical 米 (mǐ), suggesting something refined from a raw material (like polished rice).
• Together, 味精 (wèijīng) literally translates to “flavor essence.” This is a perfect description of its function: it is a refined, concentrated crystal that provides the pure essence of savory flavor.

For decades, 味精 was a cornerstone of Chinese home and restaurant cooking, just as essential as salt or soy sauce. Its ability to create a deep savory flavor, known as `鲜 (xiān)` or umami, made it an inexpensive and effective way to elevate simple dishes. Many older Chinese cooks consider it an indispensable part of their pantry. The cultural story of 味精 becomes complex when viewed from a Western perspective due to the phenomenon known as “Chinese Restaurant Syndrome.” In the late 1960s, a narrative emerged in the United States linking symptoms like headaches, numbness, and palpitations to eating at Chinese restaurants, with MSG being singled out as the culprit. This created a lasting stigma around both MSG and, by extension, Chinese cuisine in the West. It is crucial for learners to understand that extensive, double-blind scientific studies have since failed to establish a clear, consistent link between MSG consumption and these symptoms in the general population. While a small percentage of people may have a sensitivity, the “syndrome” is now widely regarded by the scientific community as a xenophobic myth. In modern China, while a health-conscious movement has led some to reduce its use, 味精 is not viewed with the same level of suspicion as it often is in the West. It is seen more as a traditional, perhaps slightly old-fashioned, ingredient rather than a dangerous chemical.

• In the Kitchen: A small pinch of 味精 is often added to soups, stir-fried vegetables, meat marinades, and dumpling fillings. It dissolves easily and its purpose is to round out and boost the overall flavor profile of the dish.
• Restaurant Culture: While high-end restaurants might avoid it to emphasize the natural flavors of their ingredients, many everyday eateries and street food stalls still use it. It is now common for restaurants catering to health-conscious diners to advertise with signs that read “无味精” (wú wèijīng - No MSG) or “不含味精” (bù hán wèijīng - Does not contain MSG) as a major selling point.
• In Conversation: The health effects of 味精 are a common topic of discussion. People might complain of feeling thirsty (口渴, kǒukě) after a meal, attributing it to excessive MSG. Asking a host or a chef if they use 味精 is a normal question, though the motivation might be simple curiosity or a dietary preference.

• Example 1:
  • 很多饭店的汤里都放了味精。
  • Pinyin: Hěn duō fàndiàn de tāng lǐ dōu fàng le wèijīng.
  • English: Many restaurants put MSG in their soup.
  • Analysis: A simple statement of fact, neutral in tone. This is a common observation about restaurant cooking in China.
• Example 2:
  • 师傅，我的面里请不要放味精，谢谢。
  • Pinyin: Shīfu, wǒ de miàn lǐ qǐng búyào fàng wèijīng, xièxie.
  • English: Chef, please don't put MSG in my noodles, thank you.
  • Analysis: A polite and practical request when ordering food. “师傅” (shīfu) is a common and respectful way to address a cook or chef.
• Example 3:
  • 我对味精过敏，吃了会不舒服。
  • Pinyin: Wǒ duì wèijīng guòmǐn, chī le huì bù shūfu.
  • English: I'm allergic to MSG; I feel unwell after eating it.
  • Analysis: This sentence clearly explains a dietary restriction. “对 (duì)… 过敏 (guòmǐn)” is the standard structure for “to be allergic to…”.
• Example 4:
  • 现在很多年轻人做菜都不用味精了，他们觉得不健康。
  • Pinyin: Xiànzài hěn duō niánqīngrén zuòcài dōu bú yòng wèijīng le, tāmen juéde bù jiànkāng.
  • English: Nowadays, many young people don't use MSG when they cook; they think it's unhealthy.
  • Analysis: This sentence reflects the modern health-conscious trend and generational shift in cooking habits in China.
• Example 5:
  • 这个菜这么鲜，你是不是放味精了？
  • Pinyin: Zhège cài zhème xiān, nǐ shì bu shì fàng wèijīng le?
  • English: This dish is so savory, did you add MSG?
  • Analysis: A common question, often asked out of curiosity rather than accusation. “鲜 (xiān)” is the key adjective describing the taste that MSG provides.
• Example 6:
  • 少放一点味精可以提鲜，但放多了会口渴。
  • Pinyin: Shǎo fàng yìdiǎn wèijīng kěyǐ tíxiān, dàn fàng duō le huì kǒukě.
  • English: Adding a little MSG can enhance the flavor, but adding too much will make you thirsty.
  • Analysis: This sentence shows a balanced understanding of 味精. “提鲜 (tíxiān)” means to “bring out the umami/savory flavor.” “口渴 (kǒukě)” (thirsty) is the most common complaint associated with MSG.
• Example 7:
  • 我们家现在用鸡精代替味精。
  • Pinyin: Wǒmen jiā xiànzài yòng jījīng dàitì wèijīng.
  • English: Our family uses chicken powder instead of MSG now.
  • Analysis: This highlights a very common substitution in modern Chinese kitchens. 鸡精 (jījīng) is seen by many as a more “advanced” or flavorful alternative.
• Example 8:
  • 有些零食的配料表里也含有味精。
  • Pinyin: Yǒu xiē língshí de pèiliàobiǎo lǐ yě hányǒu wèijīng.
  • English: The ingredient lists of some snack foods also contain MSG.
  • Analysis: Demonstrates that 味精 is not just for restaurant food, but is a common industrial food additive. “配料表 (pèiliàobiǎo)” means “ingredient list.”
• Example 9:
  • 奶奶说，没有味精的菜就没有灵魂。
  • Pinyin: Nǎinai shuō, méiyǒu wèijīng de cài jiù méiyǒu línghún.
  • English: Grandma says that a dish without MSG has no soul.
  • Analysis: A humorous and evocative sentence showing the perspective of the older generation, for whom 味精 was a revolutionary and essential ingredient.
• Example 10:
  • 味精的主要成分是谷氨酸钠。
  • Pinyin: Wèijīng de zhǔyào chéngfèn shì gǔ'ānsuānnà.
  • English: The main component of MSG is monosodium glutamate.
  • Analysis: A scientific and formal sentence providing the chemical name, useful for advanced learners or those interested in food science.

• “False Friend” with Salt: Do not confuse 味精 (wèijīng) with 盐 (yán - salt). While both are white crystals used for seasoning, they provide completely different tastes. 味精 adds savory depth (umami), while 盐 adds saltiness. They are not interchangeable.
• 味精 (wèijīng) vs. 鸡精 (jījīng): This is a critical distinction in modern China.
  • 味精 (wèijīng): Pure monosodium glutamate (99%+). Its only job is to add umami.
  • 鸡精 (jījīng - chicken essence/powder): A compound seasoning. It contains MSG as its main ingredient, but also includes salt, sugar, and chicken flavoring. It provides a more complex, chicken-broth-like flavor. Many households have completely replaced 味精 with 鸡精.
• Navigating the Health Debate: When discussing 味精, be aware of its controversial history. Avoid making definitive statements that it is “poisonous” or “perfectly harmless.” Acknowledge that while science has debunked the “Chinese Restaurant Syndrome,” personal sensitivities and dietary preferences are valid. Using phrases like “听说 (tīngshuō - I've heard that…)” or “有人说 (yǒurén shuō - some people say…)” can be a more sensitive way to broach the topic.
