中文摘要:

      目的 基于国家营养监测要求对甘肃省内常见48种甜点中维生素含量情况进行检测。方法 以甘肃省内常见的48种甜品为研究对象, 采用食品安全国家标准中规定的高效液相色谱法对样品中维生素A、胡萝卜素、维生素B1、维生素B2、维生素C、维生素E以及维生素E(包括α-生育酚、β-生育酚、γ-生育酚和δ-生育酚)的含量进行检测。结果 48种甜品中除去维生素B1均未检出外, 其余维生素检出率从高到低为维生素E>维生素B2>维生素A>胡萝卜素>维生素C; 样品中维生素A含量为未检出~549.000 μg/100 g,中位数为20.000 μg/100 g; 胡萝卜素检出含量为未检出~142.650 μg/100 g, 中位数为0.250 μg/100 g; 维生素B2检出含量为未检出~0.226 mg/100 g,中位数为0.090 mg/100 g; 维生素C检出为未检出~4.740 mg/100 g, 中位数为0.250 mg/100 g; 维生素E(各分型之和)检出含量为未检出~549.000 mg/100 g,中位数为21.650 mg/100 g; α-生育酚检出含量为未检出~2.690 mg/100 g, 中位数为1.015 mg/100 g; β-生育酚检出含量为未检出~1.240 mg/100 g, 中位数为0.02 mg/100 g; γ-生育酚检出含量为未检出~11.810 mg/100 g, 中位数为1.135 mg/100 g; δ-生育酚检出含量为未检出~2.040 mg/100 g, 中位数为0.020 mg/100 g。结论 脂溶性维生素在甘肃省内甜点样品中检出含量普遍较高, 水溶性维生素检出均较低。

英文摘要:

      Objective To investigate the vitamin content in common 48 kinds of desserts in Gansu Province based on the requirements of national nutritional monitoring. Methods A total of 48 kinds of common desserts from Gansu Province were analyzed. The content of vitamin A, carotene, vitamin B1, vitamin B2, vitamin C, vitamin E and vitamin E fractions, i.e. (α-tocopherol, β-tocopherol, γ-tocopherol and δ-tocopherol) were determined by high performance liquid chromatography method as specifiedin the national standard for food safety. Results The results showed that among the 48 kinds of desserts, except for vitamin B1, the detection rates of other vitamins ranged from high to low: Vitamin E>vitamin B2>vitamin A>carotene>vitamin C; the content of vitamin A in the sample is ND-549.000 μg/100 g, median of 20.000 μg/100 g; the content of carotene was ND-142.650 μg/100 g, median of 0.250 μg/100 g. The content of vitamin B2 was ND-0.226 mg/100 g, median of 0.090 mg/100 g; The content of vitamin C was ND-4.740 mg/100 g, median of 0.250 mg/100 g. The detected content of vitamin E (sum of various subtypes) ranges was ND-549.000 mg/100 g, median of 21.650 mg/100 g; the content of α-tocopherol was ND-2.690 mg/100 g, median of 1.015 mg/100 g; the content of β-tocopherol was ND-1.240 mg/100 g, median of 0.020 mg/100 g; the content of γ-tocopherol was ND-11.810 mg/100 g, median of 1.135 mg/100 g; the content of δ-tocopherol was ND-2.040 mg/100 g, median of 0.020 mg/100 g. Conclusion The fat-soluble vitamins are generally detected at higher levels in the samples from Gansu Province, while the water-soluble vitamins are detected at lower levels.
