面粉中过氧化苯甲酰的检测方法研究进展加外文加翻译分析报告.docVIP

面粉中过氧化苯甲酰的测定 摘 要 本论文首先从过氧化苯甲酰的性质、效用、毒性、用量等方面进行了叙述，过氧化苯甲酰作为面粉添加剂，主要有4 大功能: 增白、后熟、防腐及提高出粉率。过氧化苯甲酰对维生素B1、B2、C、E、K 和胡萝卜素产生氧化作用，破坏了面粉的营养成分; 过量食用含过氧化苯甲酰的面粉会加重肝功能不健全人群的肝脏负担，短期过量食用易产生恶心、眩晕、神经衰弱等症状，长期过量食用会严重损坏肝脏. 然后列出几种过氧化苯甲酰的测定方法，综述了近年间过氧化苯甲酰检验方法的研究，包括样品前处理及定性分析、定量检验的原理及检出限等。检测方法主要为5类，化学分析法、光谱法、色谱法、质谱法及电化学法，并对面粉中过氧化苯甲酰分析方法进行了总结和讨论。 最后对过氧化苯甲酰剂量使用规定存在的问题进行了阐述和提出了相关的建议，通过对面粉添加剂过氧化苯甲酰的研究学习，让我们可以通过所学知识与实际结合起来解决生活中的相关问题 关键词：面粉; 过氧化苯甲酰; 检验方法 Testing Methods for the Determination of Benzoyl Peroxide in Flour Abstract This paper first from the nature, utility, toxicity, dosage and other aspects of benzoyl peroxide in this article, BPO as flour additives, there are mainly four functions: whitening, after ripening, antisepsis and improve flour yield 。benzoyl peroxide of vitamin B1, B2, C, E, K and carotene oxidation, destroyed the flour nutrients; Excessive edible flour containing benzoyl peroxide can increase the liver liver diseased population burden, short-term excess mucus produce symptoms such as nausea, dizziness,neurasthenia,long-term excessive consumption will seriously damage the liver. Then list several methods of determination of benzoyl peroxide ,which covering mainly the last decade and relating especially to sample pretreatment，qualitative analysis and quantitative inspection principle，detection limit etc.were presented． The testing methods were divided into five types: chemical analysis，spectrometry，chromatography，mass spectrometry and electrochemical analysis． The methods for testing the benzoyl peroxide added in flour were discussed and summarized． Finally the problems existing in the use of benzoyl peroxide dosage regulations are expounded and put forward some Suggestions, through the study on flour additive Benzoyl peroxide study, so that we can through the knowledge combined with the actual solve related problems in life. Key words: flour，benzoyl peroxide，testing methods 目　录 前　言 4 第1章 面粉中的过氧化苯甲酰 6 1.1面制品质量的评价 6 1.2过氧化苯甲酰的物理性质 6 1.3过氧化苯甲酰
