ABSTRACT:
Sea buckthorn berry juice and aqueous extracts obtained from sea buckthorn berry and leaf tissue provide an ice nucleating agent and thereby operate, upon addition of the juice and/or extract to a freezeable food product, to increase the freezing temperature of the food product. A protein and a protein-lipid aggregate having the ice-nucleating activity may be isolated from the juice and/or extract. The extracts may be obtained by extracting the tissue with an aqueous solution containing a saccharide, particularly pectin alone or in combination with another saccharide.
