Rapporten presenterer estimater for framtidig tilgjengelig kvantum av GROT (greiner og topper) fra sluttavvirkning i Innlandet, basert på avvirkningsstatistikk fra Statistisk sentralbyrå og Landsskogtakseringens registreringer i fylket i perioden 2016-2020. Rapporten er utarbeidet på oppdrag fra Stasforvalteren i Innlandet.

The demand for meat products is rising globally. A potential substitute for meat is synthetic meat, meat produce d in the laboratory. Synthetic meat is not in the market yet due to high production costs and regulatory issues, but it will probably be available during the next decade. If cheap and popular it may crowd out the demand and production of farmed meat and herby affect farmers income. In this study we have used data from a choice experiment in Norway to construct price and income elasticities for synthetic meat with three different assumptions. The data shows that half of the population does not accept synthetic meat. They will not buy it whatever the price. The own-price elasticities were estimated to be in the interval [-0.47,-0.08] and the cross-price elasticities were in the interval [0.09,0.40]. The income elasticities were all close to 0. If these elasticities were valid in a situation in which synthetic meat is available on the market, we could infer that the market for synthetic meat is limited.

Fish waste (FW) contains large amounts of protein and is a challenging feedstock for biogas production due to possible H₂S and ammonia generation. Adding FeCl3 to an anaerobic digester can precipitate H₂S. Mackinawite and greigite are conductive and magnetic substances formed from H₂S precipitation. Direct interspecies electron transfer (DIET) can be stimulated by developing these conductive materials and by applying an external magnetic force. In this study, FW was digested in batch reactors and exposed to magnets magnetic fields from 3 to 115 mT. The results showed that the use of magnetic fields could increase the biomethane yield by up to 36 %. XRD analyses showed that mackinawite and greigite were accumulating in the solid phase in digesters added FeCl3. Genetic analysis of the microbial community suggested that applying a magnetic field not only increased the relative abundance of protein-hydrolyzing bacteria but also potentially improved methane production through DIET.

Dette prosjektet har hatt fokus på lagringsforholdene for potet til fritering, og på å redusere økningen i mengde akrylamid som naturlig skjer på lager. Innhold av akrylamid er en viktig faktor for lønnsomhet og bærekraft i produksjonen av friterte potetprodukter. Akrylamid dannes ved sterk oppvarming av stivelsesholdig mat og er knyttet til utvikling av kreft. Chips og pommes frites konsumeres av alle aldersgrupper, og det har derfor vært stort press på potetindustrien for å senke nivåene. Målet med prosjektet var å oppnå bedre produktkvalitet, lavere akrylamidinnhold og en mer lønnsom og bærekraftig produksjon av norsk chips og pommes frites. Målet skulle nås gjennom kunnskap om samspillet mellom råvarekvalitet og lagringsforhold. Acrylamide has become an important measure when looking at profitability and sustainability in the potato processing industry. Acrylamide is a possible carcinogenic which is formed in starchy foods during high-temperature cooking processes. Crisps and French fries are consumed by people of all ages and therefore the pressure on the industry has been large to reduce the levels. The aim of the project was to reduce acrylamide content and improve product quality profitability and sustainability in the production of crisps and French fries. Knowledge about the interaction between potato quality and storage conditions were important measures. The importance of elevated CO2 levels on product quality and acrylamide content, was studied.
