![]() ![]() Lingonberry (Vaccinium vitis-idaea) is one of the most abundant and economically important wild berries in the Nordic countries. At the same time, on the market the Norwegian wild berries are almost non-existent and berries are left unexploited. In our neighbouring countries, Sweden and Finland, wild berries are already a big industry. These areas are abundant in valuable renewable resources, including wild berries. Results from analysis of berries collected in 20 are necessary to have the basis to draw a conclusion on how biotic and abiotic factors influence anthocyanin content of lingonberries.Īlmost 95% of the area in Norway is wilderness and 38% of the land area is covered by woods. However, as the variation was as large within the stands of each location as they were between the locations, different growth factors would also play key parts in synthesis of anthocyanins in lingonberries. There appears to be a variation in anthocyanin concentration linked to latitude. The total content of anthocyanins in lingonberries ranged from approximately 320 to 790 mg 100 g‑1 dw. ![]() Additionally, small quantities of three other cyanidin glycosides were preliminarily identified. The three major anthocyanins in Norwegian lingonberries were cyanidin-3-galactoside (69-90%), -arabinoside (6-23%) and -glucoside (2-10%). Phenolic compounds were analysed by HPLC-DAD-MSn, with quantification of anthocyanin at 520 nm and MS used for identification. Berries from each sector were lyophilised and extracted with 70% methanol. Within each location, eight stands (250 m2) with different biotic conditions were chosen. Eight locations across Norway (58 to 69°N) with supposed high production potential of lingonberries were selected. Here, anthocyanin content in berries from the first growth season is presented. A three-year study (2019-2021) with 64 field plots across Norway have therefore been set up, with the aim of studying the effect of climate and growth conditions on lingonberries. The large variations in abiotic and biotic growth conditions have potential to influence quality and availability of lingonberries. These small red fruits grow across Norway, a country with large variations in abiotic and biotic growth conditions. Lingonberries (Vaccinium vitis-idaea L.) have received much positive attention due to their exotic taste and high phenolic content. In the time of bioeconomy an unexploited environmentally friendly resource is too good to leave untouched. We believe that the knowledge will have high transfer value for other wild berry species and non-wood forest products.īy interdisciplinary collaboration from start to the end of the value chain, WILDBERRIES seeks to meet the key challenges for an increased utilization on a renewable resource. The focus will be on lingonberry and in selected high yielding areas. Furthermore, to increase possible value creation, WILDBERRIES will enlighten innovation potential and new product opportunities. However, innovative solutions and new knowledge on quality aspects can open possibilities for innovation and value creation. Due to high labour costs, Norwegian raw material cannot compete on product price. In order to utilize the wild crop commercially, it must be profitable. By utilizing knowledge and modelling expertise from Finland, WILDBERRIES seek to develop tools in order to map areas with high yields and/or high quality of wild berries as well as getting new knowledge on key climatic conditions, which affect the yield. The availability and quality of wild berry yield varies from year to year and from locations to location. One of the key challenges is the access to the berries in the Norwegian topography. ![]() Nevertheless, Norwegian wild berries are almost non-existent on the market, leaving the berries unexploited in the forests. In Norway, the everyman's right allows picking of wild berries no matter who owns the land. In our neighbouring countries, wild berries are already a big industry. ![]()
