1. A crosslinked molecularly imprinted polymer (MIP) for extraction of at least one target molecule component of wine, the MIP consisting essentially of polyvinylpolypyrrolidone (PVPP) molecularly imprinted to have specific affinity for binding with the target molecule component of wine, the target molecule component of wine being a flavor component, the PVPP being molecularly imprinted with 2-isobutyl-3-methoxypyrazine (IBMP), 2-methoxypyrazine, 2-phenyl ethyl alcohol, guaiacol or 4-methyl guaiacol.
