Abstract: The current research progress of evaluation technologies for apples with different quality indices including sensory quality (size, shape index, skin color, and flavor component contents), physiochemical and nutritional quality (vitamin C content, soluble solid content, acidity, and mineral and protein contents) and processing quality (firmness, browning degree, moisture content and edible rate) are summarized in this paper. The further development trend of apple quality evaluation technologies is also proposed.
