水解蛋白注射液因含有十多种氨基酸,是重要的蛋白质营养剂,故在生产过程中极易被微生物污染,产生热原。国内目前多采用活性炭常规吸附法除去热原,此法不仅活性炭用量大,吸附次数多,而且不彻底。为此我厂在制备工艺上进行改进,兹将初步经验简介如下。一、方法取水解蛋白浓缩液按总氮稀释至2％左右,加入0.5％活性炭,于120℃保温2小时,放置过夜;次日加1.2％活性陶土加温搅拌45分钟,过滤;滤液再加1.5～2％活性炭 Hydrolyzed protein injection contains more than 10 kinds of amino acids, is an important protein nutrients, it is easily contaminated by microorganisms in the production process, produce pyrogen. Domestic use of activated carbon conventional adsorption method to remove pyrogen, this method is not only a large amount of activated carbon adsorption times, but not completely. To this end I plant on the preparation process to improve, I hereby introduce the initial experience is as follows. First, the method to take the hydrolyzed protein concentrate diluted to 2% of total nitrogen by adding 0.5% activated carbon, incubated at 120 ℃ for 2 hours, placed overnight; the next day plus 1.2% activated clay heated for 45 minutes, filtered; the filtrate plus 1.5 ~ 2% activated carbon
