番茄中番茄红素含量无损检测的研究

STUDY ON THE NON-DAMAGE MEASURE METHOD OF LYCOPENE CONTENT FOR TOMATO FRUIT

实验通过苏丹Ι色素标准溶液,以及番茄样品的测定,寻找扫描仪的R、G、B、H2、I与色差计中的X、Y、Z、H1、L值及色素含量之间的相关性。实验结果显示:色差仪的X,Y,Z值和扫描仪的R,G,B值相关性均达到极显著水平。对番茄样品的测定表明,H1和H2值的相关性达到极显著水平。色差计测定的X,Y,H1和L值与番茄样品的番茄红素含量的相关性均达到极显著水平,其相关系数分别为-0.9382,-0.9763,-0.9174,-0.9653。扫描仪的H2值与番茄样品的番茄红素含量相关性达到极显著水平,相关系数R为-0.9475。显然色差计的Y值比扫描仪的H2值与番茄样品的番茄红素含量相关性更好。可以利用色差仪的Y和L值,以及扫描仪的H2值计算番茄样品的番茄红素含量。

The content of standard Sudan dye Ⅰ and the lycopene Content of tomato were studied. The results showed that there were significantly close relativity between the Sudan content of standard solution and the data of X or Y or Z of Different Color Meter and the data of R or G or B of Scanner. The result of tomato fruit color determine showed that the relationship of H1 and H2 were significant.The data of X,Y,H1 and L of Different Color Meter and the lycopene content of tomato had significantly close relativity. These correlation coefficient were - 0.938 2,-0.976 3,-0.917 4,-0.965 3, respectively. The data of H2 of Scanner and the lycopene content of tomato had significantly close relativity, too. The correlation coefficient was -0.947 5.The relationship of data of Y of Different Color Meter with the lycopene content of tomato was closer than the relationship between the data of H2 of scanner and the lycopene content of tomato. The lycopene content of tomato can be calculated by the parameters of Y and L of Different Color Meter and the data of H2 of scanner according to the regression equation.
