Introduction to the
The concept of yeast powder and yeast dip some easily confused. Yeast powder and yeast powder is similar to play a role in the fermentation, are providing microbial organic nitrogen source and vitamins, hormones and other nutrition. Yeast powder is also called the powdery yeast extract, its rich nutrition, high protein content, and contains 18 kinds of amino acids necessary for human body and functional peptides (including glutathione), some types also contain prandial fiber, dextran and mannan.zymosan nucleic acid (RNA) of the human body and nucleotide, vitamin B group, rich in a variety of trace elements, is a kind of high nutritional value of natural flavoring.
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. However, as people living standard rise and "precious is natural, return to natural life philosophy, the formation of MSG would gradually reduce freshness agents in mainland China market of the market share.
