Monosidum glutamate raw material liquid as well as preparation method and application thereof

The invention relates to the technical field of food technology, and discloses monosodium glutamate raw material liquid as well as a preparation method and application thereof. The light transmittance of the monosodium glutamate raw material liquid is greater than or equal to 95%, and the pH value of the monosodium glutamate raw material liquid is 6-7.5; On the basis of the total weight of the monosodium glutamate raw material liquid, the monosodium glutamate raw material liquid contains 40-50wt% of sodium glutamate, 0.02-0.08wt% of chloride ions, 0.00015-0.0003wt% of iron ions, 0.02-0.08wt% of sulfate and 45-65wt% of water. The monosodium glutamate raw material liquid with high purity and few impurities can be obtained, so that the monosodium glutamate conversion rate and the monosodium glutamate crystal quality which are higher than those in the prior art are obtained. 本发明涉及食品工艺技术领域，公开了一种味精原料液及其制备方法和应用。该味精原料液的透光率≥95％，所述味精原料液的pH值为6-7.5；以所述味精原料液的总重量为基准，所述味精原料液中含有40-50wt％谷氨酸钠、0.02-0.08wt％氯离子、0.00015-0.0003wt％铁
