Four samples of neutral fractions of protein hydrolysates were separated by gas chromatography and the individual components were identified from the mass spectra obtained. Some of the identified compounds were not previously reported as volatile components of foodstuffs. Three of these compounds namely 3-chloropropan-1-ol, 2,3-dichloropropan-1-ol, and 1,3-dichloropropan-2-ol, were toxic chlorohydrins. 1,3-Dichloropropan-2-ol was present in samples in concentrations 0.17 to 0.94 mg/kg. To check the possibilities of the formation of these chlorohydrins and to find their precursor, glycerol, and hydrochloric acid mixtures were heated under conditions of producing protein hydrolysates. All three chlorohydrins, formerly found in protein hydrolysates have been identified.
蛋白质水解产物的四个中性馏分样品通过气相色谱法进行分离，并根据所得质谱图鉴定各个成分。一些鉴定出的化合物以前未被报道为食品的挥发性成分。其中三种化合物，即3-氯-1-丙醇、2,3-二氯-1-丙醇和1,3-二氯-2-丙醇，是有毒的氯代醇。1,3-二氯-2-丙醇在样品中的浓度为0.17至0.94毫克/千克。为了检验这些氯代醇的形成可能性并找到它们的前体，将甘油和盐酸混合物在产生蛋白质水解产物的条件下加热。以前在蛋白质水解产物中发现的所有三种氯代醇都已被鉴定出来。
