Abstract:

Apple is an important part of Chinese diet. Apple quality is increasingly concerned and the market, especially the high-end market for apple quality requirements are increasing day by day. One hundred and seventy six ‘Fuji’ apple samples were collected from orchards of 8 main apple producing provinces, including Hebei, Henan, Liaoning, Shandong, Shanxi, Shaanxi, Ningxia and Xinjiang. Fifteen indexes were tested for each sample, including single fruit weight, fruit firmness, total soluble solid, soluble sugar, titratable acidity, vitamin C, sorbitol, glucose, fructose, sucrose, sweetness value, the ratio of total soluble solid to titratable acidity, the ratio of soluble sugar to titratable acidity, a the ratio of sweetness value to titratable acidity. The aim of this study was to establish the quality basic database of ‘Fuji’ apple. Through the establishment of ‘Fuji’ apple quality dataset, the nutritional quality of ‘Fuji’ apples from different production areas in China can be systematically mastered, the differences of ‘Fuji’ apples from different production areas can be explored, and the influencing factors can be explored. This study also provided theory basis for apple industry development and quality evaluation.
