Embodiment Construction

[0028] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited to the scope expressed in the examples.

[0029] The core idea of ​​the present invention uses high-performance liquid chromatography to measure the content of lycopene in different tomato paste samples, and performs an attenuated total reflection infrared spectrum test on the samples. The spectral data of the calibration set samples were processed and modeled, and the regression equation was verified using the validation set samples to establish a rapid detection method for lycopene in tomato paste. The invention was tested through the following research process:

[0030] 1. Determine the infrared spectrum analysis band range of lycopene in tomato paste

[0031] The infrared spectrum of lycopene and the infrared spectrum of tomato paste samples are as follows figure 1 , the wave number of lycopene is 1800-950cm -1 T...

Abstract

The invention relates to the field of food examination and detection, and concretely relates to a method for determining lycopene in catsup through infrared spectroscopy. The method for determining lycopene in catsup through infrared spectroscopy is characterized in that 1700-950 cm<-1> is used as the infrared spectroscopic analysis waveband of lycopene in the catsup, and a model between the content of the lycopene in catsup and infrared spectroscopic data is Y = -16.9*F1 + 3.58*F2 - 0.98*F3 - 1.75*F4 + 0.22*F5 - 1.28*F6 - 1.54*F7 + 1.65*F8, wherein Y is the content of the lycopene in catsup, and F1, F2, F3, F4, F5, F6, F7 and F8 are main components obtained after main component analysis of the catsup infrared spectroscopy. The method has the advantages of obtaining of visual and reliable information, strong practicality, rapidness, accuracy, practicality, economy, and easy promotion and use.

Description

technical field [0001] The invention relates to the field of food inspection and detection, in particular to a method for measuring lycopene in tomato paste by using infrared spectroscopy. Background technique [0002] Lycopene is composed of 11 conjugated double bonds and 2 non-conjugated double bonds. It is a functional natural pigment with anti-oxidation, scavenging free radicals, effective prevention and treatment of tumors and cardiovascular and cerebrovascular diseases, delaying aging, improving The ability of immunity. Therefore, the content of lycopene has become the ultimate standard of tomato product quality, and the content of lycopene is used as the grading standard of tomato paste quality at home and abroad. At present, high performance liquid chromatography has high precision in determining lycopene, and can eliminate the interference of other components, and can effectively quantify and identify counterfeit. However, the cost of instruments is very high, sam...
