i was reading an aticle on MSG recently .Here's an extract .
I like the idea of the Popadom oil though . that would definately have flavour .

Monosodium glutamate is the sodium salt of glutamic acid. When MSG is added to foods, it provides a similar flavouring function as the glutamate that occurs naturally in food.

MSG is a flavour enhancer that has been used effectively to bring out meaty taste in foods. Many researchers also believe that MSG imparts a fifth taste, independent of the four basic tastes of sweet, sour, salty and bitter. This taste, called "umami" in Japan, is described as savoury or meaty.
Originally commercial MSG was extracted from natural protein-rich foods such as seaweed. Today MSG is produced by a natural fermentation process that has been used for hundreds of years to make such common foods as beer, vinegar and yoghurt.

The natural flavour-enhancing levels of glutamate in food varies greatly, but is high in foods such as tomatoes, mushrooms and parmesan cheese. MSG enhances many but not all food flavours through the interaction between glutamate and other flavours. It works well with a variety of foods including meats, poultry, seafood and many vegetables. It is used to enhance the flavour of some soups, stews, meat-based sauces and snack foods. MSG harmonises well with salty and sour tastes, but does little for sweet foods such as cakes, pastries or candies.


Hope this is of interest
