Abstract: A method of preserving delicate biological substances or organic compounds (a) in a dry state and/or (b) at elevated temperatures and/or (c) under irradiation comprises incorporating in a system containing the said substances or compounds, a sugar or a sugar derivative selected from (i) a non-reducing glycoside of a polyhydroxy compound selected from sugar alcohols and other straight chain polyalcohols, or (ii) a non-reducing oligosaccharide selected from raffinose, stachyose and melezitose. In particular, methods for preserving dehydrated agarose gels comprising adding lactitol or glucopyranosyl-mannitol or glucopyranosyl-sorbitol to the gel during formation and prior to dehydration are disclosed.

Abstract: A method of preserving live viruses comprises subjecting an aqueous system containing the virus to drying either in the frozen state or at ambient temperature, in the presence of trehalose.

Abstract: A method of drying a water-containing foodstuff or beverage at a temperature above ambient, is characterized by incorporating trehalose into the foodstuff or beverage which is to be dried.

Abstract: Sensitive proteins and other macromolecules, such as enzymes, antibodies, antigens, serum complement, fluorescent proteins, vaccine components, polysaccharides such as agarose etc, can be preserved by drying at ambient temperature and at atmospheric pressure in the presence of trehalose. A porous matrix impregnated with trehalose is provided as a receiver for a blood or other liquid sample to be dried.
