The invention relates to a processing method of lemon-flavor duck crisp chips. The lemon-flavor duck crisp chips contain the following raw material components in parts by weight: 10000 parts of duck breast meat and 10000 parts of pickling liquid, wherein the pickling liquid contains the following components in parts by weight: 100 parts of cooking wine, 100-250 parts of table salt, 9-110 parts ofmonosodium glutamate, 70-85 parts of fresh ginger, 40-60 parts of green onion, 15-30 parts of anises, 20-40 parts of folia perillae acutae powder, 40-70 parts of fresh lemon slices and 8500-9500 partsof water. The processing method comprises the steps of selecting the fresh or frozen duck breast meat, carrying out cleaning, cutting the fresh or frozen duck breast meat into meat blocks, putting the meat blocks into the prepared pickling liquid for pickling, carrying out leaching, blow-drying and quick-freezing, carrying out vacuum frying on the frozen raw material, mixing the material with curry powder and spice powder, and carrying out drying, carrying out sieving by virtue of a sieving net, and carrying out packaging. By utilizing a method for combining folia perillae acutae with the lemon slices, the fishy smell of the duck meat is effectively removed, and a special flavor is brought to a product. A quick-freezing process is utilized before the vacuum frying, so that the shape of the product is fixed; moisture in intercellular spaces is acutely vaporized and swelled in the subsequent vacuum frying process, so that the form of the product is stabilized, and meanwhile, the productbecomes crispier.
