Abstract

Abstract:

Under the new situation of the development of edible agricultural products closely linked with high quality and nutrition, a series of new words emerged, among which the “characteristic quality indicators of edible agricultural products” occupied a prominent position. The clarification of the characteristic quality indicators of edible agricultural products has a leading significance for the scientific and effective evaluation of the quality of edible agricultural products. This paper discussed the definition of characteristic quality indicators of edible agricultural products, and preliminarily provided some suggestions on the screening methods of characteristic quality indicators of edible agricultural products from the aspects of object determination, consumer investigation, literature investigation, literature information extraction, sampling index verification, specification index, and health index consideration as well as process correction. The purpose of this paper was to attract the attention of relevant functional departments, industrial groups and scientific researchers, to make the definition and screening methods of characteristic quality indicators of edible agricultural products accurate and practical, to promote the establishment of quality evaluation system of edible agricultural products, to evaluate the quality of edible agricultural products scientifically and effectively, and truly to serve the development of edible agricultural products industry.

Key words: edible agricultural products, characteristic quality indicators, definition, screening
