Review of progress in application visible/near-infrared spectroscopy inn liquid food detection

As a rapid, non-destructive new testing technology, Vis/near-infrared spectroscopy is increasingly widely used in agriculture products and food quality evaluation research. The United States, Japan and many European countries have made a great deal of progress in the Vis/near-infrared spectroscopy for agriculture products and food quality evaluation. Although our country has got some fruits in this area, in comparison with foreign countries, there is still a lot of work to strengthen. In the present paper, from aspects of alcohol, dairy products, fruit juices and edible oil, the authors reviewed the latest research progress in Vis/near-infrared spectroscopy in the quality evaluation of liquid food with the emphasis on the recent 5 years, analyzed the advantages of this technique's application to the quality evaluation of liquid foods. Finally, problems existing in the applications were analyzed and solutions to them were proposed. Based on a study of the issue, this article outlined the further study and made a number of recommendations.
