Abstract
Numerous species of wild berries are abundant in the Nordic forests, mountains and peat lands. They ripen throughout the early summer until late autumn. Both lingonberry (Vaccinium vitis-idaea) and bilberry (Vaccinium myrtillus), that are among the most picked wild berries, are characteristic field layer species in boreal forests. Other species that have potential of better exploitation are cloudberry (Rubus chamaemorus), crowberry (Empeterum nigrum), bog blueberry (Vaccinium uliginosum), arctic bramble (Rubus arcticus), wild strawberries/woodland strawberries (Fragaria vesca) and wild raspberries (Rubus idaeus). Here we present a mini-review about properties and potentials of Nordic wild berries.

«Nudges» eller såkalte små dytt kan gjøre det lettere for folk å ta bedre valg, som (for eksempel) å spise sunnere, uten å begrense valgfriheten/tilgjengeligheten. Denne studien undersøkte om små endringer eller dytt i en sykehuskantine kunne hjelpe pasienter til å velge sunnere og mer «hjertevennlig mat». Prosjektets mål var å utvikle og teste ut et sett med enkle og lite kostbare «nudging»-metoder som gjør det lettere å velge mer helseriktig mat, å vise om metodene eller tiltakene gav endringer i spiseatferd og lage en praktisk veileder som beskriver resultatene og erfaringene fra prosjektet slik at disse kan brukes av kjøkkenansvarlige på andre spiseplasser.

Biofertilizers, fertilizers made from organic residues, could replace some mineral fertilizers, reducing energy consumption and resource mining. The main treatment options are composting, anaerobic digestion, drying, pyrolysis and combustion, they can be used alone or in combination. The quality of biofertilizers depend both on the original residue and on the treatment, but in most cases not all the nutrients are immediately available to plants. It is difficult to predict how available the nutrients are, and when they will become available. The methods to assess and predict nutrient availability are reviewed. Furthermore, the effect of biofertilizers on the environment in the form of nutrient losses and greenhouse gas emissions are reviewed and compared to mineral fertilizers. There is a need to produce biofertilizers with better and more predictable qualities, and also to understand their effects over multiple seasons.

A study was conducted on 124 farms in Sweden and Norway where fungal (all farms) and mycotoxin (100 of the 124 farms) presence was examined in wrapped forage bales. Samples were also analysed for chemical composition, and data on the bale production and storage system on each farm were collected. Fungi, analysed by three common sampling methods, were found in bales from 89% of the visited farms (110 farms). The most frequently isolated fungal species from the bale surface was Penicillium roqueforti. Mycotoxins were present in 39% of the 100 samples analysed. The most common mycotoxins present were enniatin B (14 farms) followed by deoxynivalenol (12 farms). The risk of finding fungi in baled forage samples was higher with odds ratio (OR) of 5.1 when less than eight layers of stretch film were applied, low seal integrity of wrapping (OR 172 at <10 s of seal integrity), higher dry‐matter content (OR 1.17–1.56 per % unit DM) and higher concentrations of acetic acid (OR 47.5 per g DM) and ethanol (OR 3.4 per g DM). Mycotoxin presence was not found to be correlated with any of the chemical characteristics of the baled forage, or with any forage production and management factors. A positive correlation was present between total fungal counts and general mycotoxin presence, but not between specific mycotoxins and the toxin‐producing fungal species.

The aims of this study were to find out if organic apple juice (AJ) contained higher contents of polyphenols or patulin compared to conventional AJ, and if higher storage temperature before processing increases patulin content in juice. AJ was pressed from Estonian, Danish and Norwegian apples. Additionally, three cultivars from Estonian organic and conventional orchards were stored at 3±2 °C and 9±2 °C before processing. Patulin, polyphenol content and antioxidant capacity were determined in pasteurized juices. In 2015, 33% of conventional (n=6) and 46% of organic (n=11) juices contained patulin; two of the organic juices above the legal limit (191 and 64µg l-1). In 2016, none of the AJs contained patulin. Patulin occurrence was more affected by weather conditions two weeks before harvest than by cultivation system and apple storage temperature. Polyphenol content was higher in organic than in conventional juices and was reduced at higher apple storage temperature.
