Abstract:

To explore the nutritional and quality differences of Lanmei 1 blueberry fruits from four production areas, Zhejiang, Sichuan, Jiangxi, and Anhui, this study compared the metabolite profiles of fruits from different origins through metabolomic analysis and nutritional indicator determination, and selected blueberries from Sichuan for processing suitability investigation. A total of 2 167 metabolites were identified. Compared with other origins, Zhejiang blueberries exhibited a larger number of significantly differential metabolites, rich in unique components such as organic acids, esters, flavonoids, and their derivatives; Sichuan and Anhui blueberries showed relatively abundant differential metabolites, containing more flavonoids and organic oxygen compounds; Jiangxi blueberries had the highest content of organic oxygen compounds but lower uniqueness in flavonoids and anthocyanins. Metabolic pathway analysis indicated that, compared with Zhejiang, metabolites in Sichuan and Jiangxi blueberries were enriched in amino acid and linoleic acid metabolism pathways, while Anhui blueberries were enriched in flavonoid biosynthesis pathways. Due to higher vitamin C and soluble sugar content, Sichuan blueberries were more suitable for processing than for fresh consumption. Evaluation of their basic processed products showed that preserved fruits retained nutrients relatively well, while juice processing requires optimization. Blueberries from Sichuan were more suitable for deep processing, such as functional foods, to fully utilize their nutritional advantages. The metabolomic data obtained in this study could provide a scientific basis for blueberry raw material selection and processing applications.
