中文摘要: 以新鲜米糠为原料,发酵生产γ-氨基丁酸(gamma-aminobutyric,GABA),对发酵液进行浓缩、喷雾干燥制备GABA 粉。以GABA 粉的溶解时间为测定指标,对喷雾压力、进料速度和进风温度进行单因素试验,通过正交试验法优化喷雾干燥的工艺参数。结果表明,最优的喷雾干燥条件为:喷雾压力0.8 MPa、进料速度0.9 L/min、进风温度140 ℃,此条件下得到的GABA 粉的溶解时间为40 s。GABA 的含量为28.71 mg/g。
Abstract:Using fresh rice bran as raw material to product GABA.The fermentation liquid was concentrated and sprayed drying to product GABA powder.Taking the dissolution time of GABA powder as the measurement index,the spray pressure,feed rate and inlet air temperature were studied using single factor test.Through orthogonal test get the best spray drying condition.The results showed the best conditions were spray pressure 0.8 MPa,feed rate 0.9 L/min and inlet air temperature 140 ℃.Under these conditions,dissolution time of GABA powder was 40 s,the content of GABA was 28.71 mg/g.
