After five years of intensive research, the research group led by Prof. Weijing Wei, Dean of the School of Life Sciences at East China Normal University, discovered that 3.98 grams of bilberry pigment can be extracted per 100 grams of bilberry pomace. This achievement has filled the blank of research on the use of slag in fruit juice extraction in China. On the 29th, the "Changbai Mountain Natural Food Resources (Bilberry) In-depth Utilization Research" project issued by the Shanghai Municipal Science and Technology Commission and the Shanghai West Project Management Center successfully passed the expert group's appraisal. At the same time, "bilberry fruit residue flavonoids for the preparation of HDL-C to reduce TC levels and prevention of hyperlipidemia drug method" has applied for invention patents, experts agreed that this project has reached the international advanced level. Vaccinium uliginosum L., commonly known as blue berry, is an evergreen dwarf shrub widely distributed in Daxinganling and Changbai Mountains. Bilberry is one of the internationally recognized human health foods, with high economic value and development prospects. So far, the medicinal components of bilberry in China have been mainly concentrated on stems and leaves and fruit juices. The subject led by Prof. Wei Jingjing has demonstrated for the first time that bilberry pigmented flavonoids extracted from bilberry pomace glycosylated in GXL system. The formation of the final product has a significant inhibitory effect; it can effectively inhibit the activity of xanthine oxidase and substrate, and reduce the accumulation of uric acid; a certain dose of bilberry fruit residue pigment and flavone can significantly reduce the content of triglyceride and cholesterol, Significantly increase the activity of SOD in serum and liver and reduce the content of MDA in serum; It can also effectively increase the content of HDL-C in hyperlipidemia serum of model animals. Bilberry pomace pigment flavonoids have a good effect on the control of hyperuricemia and hyperlipidemia, especially for the treatment of gout. The industrialization of pigments and flavonoids extracted from bilberry marc is promising. Bilberry grows more densely in the Changbai Mountain area of ​​China. According to the previous production mode, Changbai Mountain's bilberry resources are primarily processed for fruit juice, and the export purchase price is only RMB 20,000/ton, and the fruit slag is basically treated as waste. This new achievement of China Normal University adopts a "two-step" approach to make full use of the bilberry: the first step is to use the bilberry resources to research and develop new types of fruit wine; the second step is to use the rosacea after brewing to extract blueberries. Pigment flavonoids, research and development of drug health products. The bilberry has been converted into finished blueberry wine from the previous resource export type of 20,000 yuan/ton, and the output value per ton can be increased to 15-18 million yuan. According to the conservative estimate of the current size of the company, 300 tons of fruit residue a year can extract 11.94 tons of bilberry pigments and flavonoids, which is calculated at the lowest price of 4,000 yuan per kilogram and can generate economic benefits of 48 million yuan.
