谷氨酸废液制取天然调味料——酵母抽提物的研究

Study on Yeast Extract Production from the Waste Water of MGS

谷氨酸废液中含有有机物、糖及多种无机盐等成分 ,接入酵母菌种 ,通气培养可获得酵母菌体 ;再采用酶工程等技术 ,经自溶等工序而制成天然调味料——酵母抽提物。产品富含氨基酸、肽以及多肽类、呈味核苷酸、维生素及微量元素等 ,具有强烈的增鲜效应及醇厚浓郁的肉香味 ,可广泛应用在食品工业中。

The waste water of MGS, including orgnic compounds, sugar and many kinds of inorganic salts etc, can be used for producing a kind of natural flavour—yeast extract. After inoculation and aerated culture, yeast mycelium can be obtained. Autolysis and some other enzyme engineering technique were used to form the final product, which includes amino acid,peptide, polypeptide, nucleotides, vitamins, microelement and other nutrition components. Because of its strong odour increasing effect and richly meaty flavor, it has a wide applications in food industry.
