The official ingredient name of Ajinomoto MSG is L-Monosodium Glutamate (Monosodium Glutamate, E621). Under EU food law (EC No 1333/2008), it is classified within the EU as a 'flavour enhancer' and labelled with food additive code E621. MSG is the sodium salt form of glutamic acid, which occurs naturally in a wide variety of foods such as tomatoes, Parmesan cheese, and miso. When added to food in small amounts, it enhances the deep, rich taste known as 'umami', and is widely used in both Asian and Western cooking.

Yes, Ajinomoto MSG is suitable for both vegan and vegetarian diets. It contains no animal-derived ingredients whatsoever. It also holds official halal certification. As a gluten-free product, it can be used with confidence by those with gluten sensitivity. The product consists of a single ingredient: L-Monosodium Glutamate (E621).

Under EU nutrition labelling requirements, the sodium content of MSG is declared as approximately 12.3g per 100g (equivalent to approx. 30.75g salt per 100g), which may look high. However, the actual amount used in cooking is very small. Typically, only 0.5g to 2g is used per dish (serving 2–4 people) — roughly a small pinch. Compared to table salt, using MSG allows you to reduce the amount of salt needed while achieving a richer flavour, which can actually help lower overall sodium intake. The per-100g figures shown are a legal labelling requirement; the sodium consumed per actual serving is very low.

Ajinomoto (味の素) is a Japanese food company founded in Tokyo, Japan in 1909. The name 'Ajinomoto' means 'essence of taste' in Japanese, and the brand is recognised as the world's first to commercially produce and sell MSG. Both the brand origin and country of manufacture are Japan. Ajinomoto products are currently sold in over 100 countries worldwide, including throughout Asia, and have long been widely used in households and restaurants as a go-to umami seasoning.

Ajinomoto MSG should be stored in a cool, dry place away from direct sunlight, with the lid tightly closed. Exposure to moisture may cause it to clump, so always reseal the container after use. When stored correctly, it maintains its quality for an extended period. For best results in cooking, add MSG at the final stage of preparation — just before turning off the heat. MSG is heat-stable and does not break down at high temperatures, but adding it at the end allows for better control of flavour balance. Try using small amounts in soups, stir-fries, marinades, and more.
