鱼粉废水经蒸发后呈糊状 ,选择在不同种类酸、浓度、温度、水解时间、用料比的条件制取氨基酸水解液. 10 0℃、4mol?L-1盐酸、用料比 1g/5 0ml、水解 10h是最佳试验条件 ,氨基酸态氮含量高达 4 4mg?mL-1.水解液含有 17种不同浓度的氨基酸 ,其中谷氨酸含量最高占 17%,其次是天门冬氨酸、丙氨酸、精氨酸、甘氨酸、赖氨酸等.“,”After evaporated,fishmeal waste water became mushy.Amino acid hydrolyzing solution was made under the condition of different sorts of acids,chrome,temperature,hydrolyzing time and dosage proportion.It is the best experimental condition to be used under 100℃,4mol·L -1 muriatic acid,dosage proportion 1g/50ml and hydrolyzing 10 hours.The mount of amino acid nitrogen reached 4 4mg·ml -1 .Amino acid hydrolyzing solution consisted of 17 sorts of different chrome amino acid.Among them,glutamic acid is the highest.The next are asparagine acidal,alanine,arginine,glycin and lysine etc.
