Flame peeling is a food processing technique used to remove the outer skin or layers of certain fruits and vegetables. The produce is briefly exposed to high-temperature flames, which causes the skin to char or blister, making it easier to remove, often with subsequent brushing or washing.
(1) Onion and garlic: Flame peeling is a well-established and effective method for removing the dry outer skins of onions and for peeling garlic cloves, especially on a commercial scale. The heat loosens the papery skins.
(2) Pea and grains: Peas are typically shelled, not peeled by flame. Grains undergo milling or other processes, not flame peeling for consumption.
(3) Carrot: Carrots are usually peeled by abrasion or knives. Flame peeling is not a common method for carrots.
(4) Pineapple: Pineapples have a tough, fibrous, and spiky skin that is typically removed by cutting with knives. Flame peeling is not suitable for pineapples.
Therefore, flame peeling is most characteristically used for onion and garlic among the options provided.
