食品分析 一、 名词解释（3×5=15） 水分活度：食品水分的饱和蒸汽压与相同温度下纯水的饱和蒸汽压之比。 灰分：食品经高温灼烧后残留的无机物质成为灰分，它是表示食品中无机成分总量的一项指标。 准确度：是指测定值与真实值之间相互符合的程度，它能说明测定的可靠性，用误差来表示。 采样：由整批事物的各个部分采取的少量样品。 常压湿法消化法：是在常压条件下，利用强氧化性试剂将样品中的有机物分解，使其中的碳、氢、氧等元素生成易挥发的二氧化碳和水，金属元素和无机盐类留在溶液中。 二、 填空（1×20=20） （1）有效数字的修约规则＿＿＿（四舍六入五留成双） 250.650＿＿＿（保留四位有效数字）（250.6） 10.2350＿＿＿（保留四位有效数字）（10.24） （2）凯氏定氮法的正确顺序＿＿＿、＿＿＿、＿＿＿、＿＿＿（消化 蒸馏 吸收 滴定） （3）误差的种类有＿＿＿、＿＿＿、＿＿＿（系统误差 偶然误差 过失误差） （4）索氏抽提法提主要提取的是＿＿＿（游离脂肪），氯仿-甲醇法适用于的是＿＿＿的提取（结合态脂类） （5）食品灰分测定中的两个重要步骤为＿＿＿、＿＿＿（炭化 灰分） （6）还原糖的测定方法有______、__________（直接滴定法 高锰酸钾滴定法） 院部_____________ 班级___________ 姓名_____________ 学号_______________
（7）在消化反应中，加入硫酸钾是为了___________________________________________，加入硫酸铜是为了___________________________。（为了提高溶液的沸点加快有机物的分解为了起催化的作用） （8）液态食品相对密度的分析方法有________、________（密度瓶法密度天平法） 三、计算（5×4=20） 1、测定食品中含氮量时，5次平行测定的结果如下：1.49%,1.50%,1.55%,1.50%,1.80%. 试 判断有无应舍弃的可疑值（利用4d检验法） 解 1.80%离群较远，将其列为可疑值。舍去 1.80%后其余四个数据的平均值和平均偏差为 1.51% x d =0.02% 1.80%-1.51%=0.29%＞4d 故应当将其舍去 2、用分析天平称量两份样品的质量分别是3.0211克和2.3212克，如果他们的真实值分 别为3.0212克和2.3213克，则这两份样品称量的准确度哪一份较高？ 答案：E1=3.0211-3.0212=-0.0001 E2=2.3212-2.3213=0.0001 Er1=E1/T1×100%=-0.0001/3.0212=-0.0033% Er2=E2/T2×100%=-0.0001/2.3213=-0.0043% 从计算信息可知，两样品称量的绝对误差相等，但相对误差Er1>Er2,因此3.0212的那个样品准确度较高 由此看出，称量绝对误差相等时，在允许范围内称量物品越重相对误差越小，称量的准确度越高 3 、用凯氏定氮法测量某面粉中粗的质含量，精确称取样品3.100g样品，经消化后，消 化液定容至100ml，吸取10ml采用微量凯氏定氮法蒸馏（以2%硼酸溶液10ml吸收），用0.0500mol/L 标准盐的溶液滴定消耗9.80mL，求此面粉中的蛋白质含量。空白滴定消耗0.08mL盐酸溶液（面粉的蛋白质换算系数为5.70）。

食品分析试题 一、填空题（每空1分，共20分） 1实验员用等臂天平称量10g的样品来实验，实验有5个平行样，但是由于实验员的粗心大意，称量前没有校正，结果称量结果偏低，由这个引起的误差应该属于误差。 2 原料中淀粉含量的测定一般要先用乙醚和乙醇对样品进行洗涤预处理，然后在进行测定。其中乙醚洗涤的目的是，乙醇洗涤目的是。 3 液态食品相对密度测定方法通常有、等方法。 4 折光仪是利用原理测定物质折射率的仪器，食品工业中最常用的折光仪有、等。 5 化学分析法是以为基础的分析方法，主要可分为、两类。 6 食品分析样品预处理处理方法主要包括、、等。 7 水溶性灰分反映的是的含量。 8 双缩脲比色法测定重金属的原理是：样品经过消化后，在一定的酸性或碱性溶液中，重金属离子与双缩脲生成有色稳定络合物，然后用合适的有机溶剂萃取，采用比色法测定。其中铅、镉离子测定是在性质溶液中进行，锌、汞离子测定是在性质溶液中进行。 9 比旋光度定义为；比旋光度和旋光度的换算公式为。 二、单选题（每小题2分，共20分） 1（）采样一般分三步，依次获得。 A 原始样、检样、平均样 B 检样、原始样、平均样 C 检样、平均样、原始样 D 检样、原始样、试验样 2（）右图表示的准确度与精密度特点是。 A 准确度好，精密度好 B 准确度好，精密度不好 C准确度不好，精密度好 D 准确度不好，精密度不好 3（）ISO是指。 A 国际标准 B 行业标准 C 国家标准 D 地方标准 4（）下列不属于干法灰化法优点（与湿法消化相比）的是。 A 试剂用量少 B 空白值低C不需工作者经常看管 D 时间短，温度低 5（）用pH计测定某样液的pH值，该酸度为。 A 总酸度 B 有效酸度 C 外表酸度D真实酸度 6（）下列测定脂肪含量的方法中，哪个不是专门用于测定乳脂肪的？ A 氯仿-甲醇提取法 B 罗素-哥特里法C巴布科克法 D 盖勃法 7（）薄层层析法测定瓜子中糖精钠含量时，在提取过程中加入盐酸的目的是。 A 增加糖精钠在水中溶解度 B 增加糖精在水中溶解度 C 转变糖精钠为糖精，使其溶于乙醚 D 以上都不是 8（）过氧化值是测定的重要质量指标。 A 脂肪 B 淀粉 C 维生素 D 蛋白质 9（）某物质与染料2,6-二氯靛酚在酸性溶液中发生氧化还原反应，使染料溶液颜色消失，氧化的染料量与该物质的含量在一定的范围内成正比，故可比色测定，该物质为。 A 氨基酸 B V A C 葡萄糖 D V C 10（）某物质与三氯化锑可生成蓝色可溶性络合物，在620nm波长处有最大吸收峰，其吸光度与物质的含量在一定的范围内成正比，故可比色测定，该物质为。 A 氨基酸 B V A C 葡萄糖 D V C
