The blueberry industry in China has experienced rapid development over the past 20 years, and the blueberry processing industry has become an important means to extend the blueberry industry chain and increase industrial added value. With the development of agricultural E-commerce, online platforms have become crucial for selling blueberry processed products. Product details and sales information for three main types of blueberry processed products on the JD platform were obtained, including blueberry jam, blueberry wine, and frozen blueberry. Through data preprocessing and analysis, the typical commodity features of these three processed products were extracted, the sales situations were compared and analyzed and the market preferences for blueberry processed products were explored. The results showed that coverage of China on imported blueberry processed products is low, and domestically products dominate in both quantity and sales volume. The blueberry jam market is stable, and the quality and market share of domestic brands have certain advantages. The unit price of products is relatively concentrated, and the packaging forms are diverse, which meets the market demand. Blueberry wine is a niche category but holds market potential. The price differences between different brands are significant, and their packaging forms and bottle capacities are mostly the same. Consumers are more inclined to purchase products with medium or low price. As for frozen blueberry, there are fewer well-known brands. Consumers prefer low- and mid-priced products, and the quality and brand of imported products are more advantageous. Finally, according to the research conclusions, some suggestions are put forward on the development of blueberry industry, in order to achieve sustainable and healthy development of blueberry industry in the future.
