CONSTITUTION:The surface of a raw vegetable is coated with an aqueous solution of a flavonoid and an organic acid and/or a calcium salt. The flavonoid is e.g. rutin, quercetin, hesperidin, naringen, etc., and is used as a solution in a solvent such as alcohol, propylene glycol, glycerol, etc. The solution is applied to the surface of a raw vegetable e.g. by spraying, coating, immersing, etc. The coated raw vegetable may be left in an outer atmosphere or stored at a low temperature or in an inert gas.</p> |
