A method and modified fermentation intermediate are disclosed for the production of polyunsaturated fatty acid (PUFA). The method comprises heat sterilizing a fermentation medium comprising dextrose to produce a heat sterilized fermentation medium, wherein the heat sterilizing converts at least a portion of the dextrose to DP2+ sugars. The method comprises combining the heat sterilized fermentation medium with an enzyme capable of converting DP2+ sugars to dextrose, thereby producing a modified heat sterilized fermentation medium comprising more dextrose and less DP+2 sugars than without combining the medium with the enzyme. The modified heat sterilized fermentation intermediate may be placed in contact with a microorganism to produce PUFA, wherein the microorganism is capable of utilizing dextrose to produce PUFA.

The present invention aims to provide a saccharide composition suitable for a cyclic-tetrasaccharide-containing starch syrup which has low viscosity, low water activity, low coloration property, and low calorie content, and which is unlikely to cause precipitation of crystals of saccharides during storage, and to provide a use of the composition and a production method for the composition. The object is achieved by providing a cyclic-tetrasaccharide-containing saccharide composition having the following characteristics (1) to (3): (1) the saccharide composition includes a branched cyclic tetrasaccharide in addition to the cyclic tetrasaccharide, wherein the content of the cyclic tetrasaccharide with respect to the total solid content of the saccharide composition obtained by allowing glucoamylase and α-glucosidase to act on the above saccharide composition is 38% by mass or higher, on a dry solid basis; (2) the ratio of α-1,4-linked glucose in the total glucose residues constituting the saccharide composition in methylation analysis is over 9% and 15% or lower, and (3) the ratio of α-1,4,6-linked glucose in the total glucose residues constituting the saccharide composition in methylation analysis is less than 6%; and providing a use of the composition and a production method for the composition.
