Vitaminer i Norsk fisk II. Vitaminer i forskjellige organer fra makrellstørje (Thunnus Thynnus) fanget utenfor Norges vestkyst.

Abstract

Fresh samples of different organs from tuna fish (Thunnus thynnus) were collected during the summer 1952. The samples represented 100 -150 fishes and were minced and stored at -15° C during the investigation. Niacin, riboflavin, pantothenic acid and vitamin B 12 were determined by microbiological assays, and thiamine and vitamin A by physicalchemical methods. The results are summarized in Tables 1-8, which have English subtitles. The liver showed extremely high values for vitamin B12, further high values for riboflavine. Meat from tuna fish is a very good source of all the vitamins investigated.
