    Abstract: A new type of cryoprotective agents that are useful for retaining the viability and metabolic activity of frozen or freeze-dried microbial cultures, is disclosed. The cryoprotective agent comprises compounds involved in biosynthesis of nucleic acids. Methods for the preparation as well as the uses of such cultures are given. Such cultures are useful as starter cultures in the manufacturing of food and feed products. Starter cultures of the invention include culture of lactic acid bacteria, e.g. Lactococcus species as well as other species.

    Abstract: The present invention pertains to a process of improving the total yield of curcuminoids from curcuminoid-containing material. More specifically, there is provided a process wherein a second residue, previously considered a waste resulting from a crystallisation step of a curcuminoid-containing phase, is made useful by improving the colouring properties of this second residue by extraction with hexane and/or methanol at ambient temperature. The pronullnullcess improves the total yield of curcuminoids by 30-40%.
