Abstract

The invention discloses a method for making low-oil sweet potato chips. The method comprises the following steps: (1) washing and draining the sweet potatoes after peeling and slicing to obtain sweet potato chips; (2) blanching the sweet potato chips with water, After draining, dry with hot air; (3) pre-fry sweet potato chips at 110-130°C for 1-3 minutes, drain and let cool; then deep-fry at 180-200°C for 15-20s to obtain sweet potato chips; (4) After the sweet potato chips in the step (3) are deoiled, they are packaged. The invention adopts a two-step frying method, first pre-frying at 110-130°C, and then frying at 180-200°C, which significantly reduces the oil content and acrylamide content of the fried sweet potato chips, And ensure the crisp taste of sweet potato chips.
