Prøveplan – en del av kvalitetssystemet
Krav : at enhver som er ansvarlig for produksjon av mat og fôr vet
hvordan en sikrer at produktet er trygt for konsum for mennesker
og/eller dyr.
• HACCP, Risiko og kvalitetsledelse
• Tilpasset selskapet og til produktet.
• Prøvetakning/analyse til å dokumentere
• Frekvens avhengig av risiko.

Value added components
Mat & Fôr analyser
• Proteiner – aminosyreprofil, frie aminosyrer, peptider
• Fett – fettsyreprofil, oksidasjon, lipid klasse
• Karbohydrater – fiber, stivelse, sakkarider, betaglukaner
• Vanninnhold
• Vitaminer
• Mineraler

Både Kjeldahl og Leco (Dumas) metoden
bestemmer N-innholdet i prøven
Leco finner total nitrogen, Kjeldahl tar ikke med N fra
nitrat og nitritt
Leco gir noe høyere proteinresultat enn Kjeldahl
• Fordeler med Leco:
• Raskere enn Kjeldahl
• Mer miljøvennlig – bruker mindre kjemikalier

Tracing Residues and Contaminants!
Mycotoxins & Natural Plant Toxins
from Aflatoxins to Zearalenone
Organic & Process Contaminants
from Acrylamide to Xylene
Metals and Elements
from Arsenic to Zinc
Veterinary Drug Residues
from Antibiotics to Steroids
14
Tung metaller og grunnstoffer
Arsen, Kadmium, Bly, Kvikksølv
– Natrium, Iron, Jod, Selen, Calsium, Sink eller Kobber
• Finnes overalt
➢ Akkumulering av uønskede stoffer i mennesker kan ha negative
helseeffekter.
15
Heavy metal - Cadmium (Cd)
Sources:
• Used in many technical processes - rechargeable batteries, production of color pigments,
coating of metals to prevent corrosion
• Available in the environment through combustion processes or as part of sewage sludge
• Cadmium is taken up by the plants mainly by the roots from the soil and stored in the
tissue
Toxicology:
• Enrichment in the human body mainly damages kidney
• Inhaled cadmium-containing dusts (tobacco smoke) can cause lung cancer
17
Heavy metal - Arsenic (As)
Sources:
• Ubiquitous in soil (cause: volcanic eruptions / burning of fossil fuels such as coal /
petroleum)
• Released by leaching or microbial activities when growing plants in water – absorbed by
the roots of plants (e.g. rice)
• Arsenic may occur as inorganic arsenic as well as organically bound. Inorganic arsenic
compounds are classified as carcinogenic
• Some algae can store arsenic in a larger amount in organically bound form
• Fish and seafood absorb arsenic from the water - organically bound (arsenobetaine and
arsenocholine)
• Rice and rice products may contain relatively high amounts of inorganic arsenic
depending on their geographical origin
Toxicology:
• In the case of organic arsenic compounds, toxicological safety is largely assumed
• Inorganic arsenic compounds are highly toxic and classified as carcinogenic

Dioksiner og PCBs
• What are dioxins?
• What are PCBs?
• Why are these
contaminants of
relevance?
• Where do they come from?
• How do they get into food?
• How does dioxin testing
work?

Flame Retardants - An Overview (Status: 26.09.2018)
Fire fighting agent
• Used for suppression ofan existing fire
• Role:
• To cool the fire
• To coat the fuelpreventing its contactwith oxygen
