It is axiomatic that in circular dichroism studies, knowledge of the absolute configuration allows determination of the conformation, and vice versa (1). The tetracycline antibiotics are -unusually complex from a conformational standpoint, but choice of appropriate conditions allows one to obtain a

## Abstract The effect of two antibiotics (chlor‐ and oxy‐tetracycline) on the spoilage of whole iced herring is studied. Spring and summer herring were improved (taste panel assessment, determination of total volatile bases) by the antibiotics, but autumn herring were unaffected. This is attribute
