Comprehensive Utilization of Blueberry Processing By-Product Resources and Development Trend of New Business Forms

Blueberry, known as the “king of berries”, is loved by consumers because of their high nutritional value. With the rapid development of blueberry processing industry, the by-products resources generated during the processing are becoming increasingly abundant. Comprehensively improving the utilization rate of by-product resources is an important way to practice the national “grain conservation and loss reduction” strategy. Application status of blueberry processing by-products in terms of efficacy component extraction, functional activity application, biomass conversion, and intelligent food packaging was summarized. Main problems restricting the overall development of the blueberry processing by-products industry were discussed, including low level of development and utilization of by-products, incomplete extraction technology for high retention of functional components, insufficient steady-state technology for processing activity of functional extracts, and a relatively single type of high value-added functional products in the market. In view of the existing problems, it was proposed that the key measures to effectively improving the utilization of blueberry by-product resources was to tackle the high steady-state technology of active ingredients in by-products, deeply explore precise nutritional benefits of active ingredients, develop diversified and personalized functional products, and construct complete processing standards and quality assurance systems. Current situation and existing problems of resource utilization of blueberry processing by-products were systematically summarized, and rational suggestions and future development trends were proposed, aiming to provide reference for the high-value utilization and high-quality development of blueberry processing by-products.
