The potential market

 

With yeast extract on the market for freshness and material and the competition is mainly: monosodium glutamate. Animal and plant extract; Vegetable protein hydrolysate (HVP) and hydrolysis animal protein (HAP). Yeast extract more tasty than MSG is mellow, taste good, after compared with MSG can immediately feel the freshness, but short duration, lack of satisfaction, and the use of yeast extract can significantly improve the expressive force of freshness, extend the flavor of duration, make the person get taste satisfaction. But because the MSG price is low, has long been the freshness agents of choice for China market, so in a short period of time, MSG will occupy larger share of the Chinese market, the yeast extract can't compete with them.
