  • Patent number: 9376357
    Abstract: The invention discloses a method for preparing high-content zeaxanthin. In the conventional preparation methods, some methods adopt certain toxic organic solvents; some methods require the multi-step crystallization process; and some methods are featured by long reaction time, high temperature and lower product yield, thus being not suitable for industrial production. The invention adopts lutein crystal or its fatty acid ester as the raw material and utilizes isomerization reaction to produce zeaxanthin, and is characterized in that a mixed catalyst consisting of an organic base catalyst and a cocatalyst is used in the isomerization reaction, wherein the cocatalyst is palladium carbon. The invention has the advantages of simple process route, low reaction temperature, short reaction time, good product purity and high yield, thus being suitable for industrial production, and no poisonous and harmful organic solvent residues in the product, thus being suitable for the use as a food additive or drug.

  • Patent number: 9317557
    Abstract: Embodiments are directed to processing queries using schema graph traversal and to establishing a schema graph that allows queries to be answered by traversing graph nodes. In one scenario, a computer system receives a query which specifies relational tables and corresponding relationships that are to be retrieved from a relational database. The computer system accesses a schema graph that includes graph nodes representing relational tables, as well as edges that identify relationships between the relational tables. The graph nodes include relational data that was loaded from one storage area (e.g. a non-volatile storage area), and the schema graph is stored in a second storage area (e.g. a volatile storage area). The computer system then traverses the schema graph, beginning at a set of graph nodes and continuing along the edges to other graph nodes until the query has been satisfied, and then reports the results of the graph traversal.
