航天诱变育种番茄营养成分分析及评价

Analysis and Evaluation on Nutritional Components of Tomato Via Space Mutation Breeding

目的:研究2个品种的航天诱变育种番茄的营养成分,并对其功能特性进行分析。方法:分别采用氨基酸自动分析仪、原子吸收分光光度仪、高效液相色谱仪等对其蛋白质、氨基酸、矿物质及维生素C等的含量进行分析,并与原亲本番茄作比较。结果:航天育种番茄中含有丰富的营养成分,蛋白质含量高于4%,氨基酸总量达0.9g/100g,矿物质含量36mg/100g,维生素C含量72mg/100g。与原亲本比较,各项指标均发生不同程度的变化。结论:航天育种番茄营养丰富,具有良好的开发利用前景。

Objective： To determinate the main nutritional components of two kind of tomatos M1 and M2 by space mutation breeding and their parent CK. Methods： The contents of protein, amino acids, mineral elements and vitamin C were analyzed by Amino acid automatic analyzer, Atomic absorption spectrophotometer, HPLC, etc. Results： The tomatos M1 and M2 contained abundant nutritional components. The protein content was more than 4% and the total amino acid was up to 0.9 g/100 g. Besides, the content of minerals was about 36 mg/100 g and the Vitamin C was even almost 72 mg/100 g. There were changes to different degree, compared with the parent CK. Conclusions： The tomatos by space mutation breeding had high nutrition value. Thus, it provided the scientific basis for a great culturing and the further comprehensives utilization.
