Tomatoes need to be blanched in hot water for a few minutes before peeling

Tomatoes are usually blanched in hot water for 30 seconds to 1 minute, depending on their maturity and water temperature. Blanching the skin for too long may cause the flesh to soften, while insufficient time may make it difficult to peel off. There is a thin film between the tomato skin and flesh, and high temperatures can loosen this film. Make a cross cut on the top of the tomato and put it in boiling water. When heated, the skin rapidly expands and separates from the flesh. Tomatoes with high maturity have thin skin that can be easily peeled off by blanching for 10-30 seconds; Newer tomatoes need to be extended to 1 minute. The best effect is to keep the water temperature above 90 ℃, and a small amount of salt can be added to help damage the skin structure.

The water temperature drops rapidly in winter, so it is recommended to handle it in small batches. Using an induction cooker or electric kettle to maintain a constant temperature is more efficient. After blanching, immediately transfer the tomatoes into ice water. Alternating between hot and cold can further promote skin separation. People who have requirements for lycopene absorption can keep the skin, which has higher dietary fiber and antioxidant content than the flesh. Special varieties such as cherry tomatoes do not require peeling, and mini tomato skins can be consumed directly. In addition to hot water scalding, gas stoves and specialized vegetable peelers can also be used to quickly roast the skin with an open flame. Processed fruit pulp is more suitable for making sauces or cold dishes to avoid nutrient loss caused by prolonged cooking at high temperatures. It is recommended to choose naturally ripe tomatoes. artificially ripened fruits have strong skin toughness and may contain pesticide residues, so the boiling time should be extended. Tomatoes that have not been peeled during daily storage should be stored in a cool place. After peeling, they should be refrigerated and consumed as soon as possible.
