Can tofu be eaten directly with cold sauce

Tofu can be eaten directly as a cold dish, but it is recommended to choose the harder texture of northern tofu or brine tofu. Before cold mixing, it should be blanched in boiling water to kill bacteria. Tender tofu is more suitable for heating and cooking due to its fragility and high water content. The key to cold tofu lies in the selection of ingredients and processing methods. North tofu has a tight texture and high protein content, making it suitable for direct seasoning after cutting into pieces. The brine tofu has a strong bean aroma, and the microbial risk is relatively low after high-temperature braising. The blanching process can inactivate potential pathogenic bacteria, while removing bean odor and enhancing taste. The blanching time should be controlled within 1 minute to avoid nutrient loss. When cold mixed, it can be paired with natural antibacterial ingredients such as scallions, ginger, and garlic, which can not only season but also reduce food safety risks.

Some people should be cautious when consuming cold tofu. People with weak digestive function may experience bloating due to soy oligosaccharides. Unterilized bulk tofu may pose a risk of Listeria contamination, and pregnant women should avoid consuming it. After opening, commercially available boxed sterilized tofu needs to be refrigerated and consumed within 24 hours. If the surface of tofu is sticky or emits a sour taste, it has spoiled and cannot be consumed cold.

It is recommended to pair cold tofu with vegetables rich in vitamin C, such as green peppers and tomatoes, to promote iron absorption. Avoid consuming high oxalate foods such as spinach, as it can affect calcium utilization. Cold tofu that has been stored at room temperature for more than 2 hours in summer should be discarded to prevent bacterial growth. Homemade cold tofu can be mixed with a small amount of vinegar or lemon juice to stimulate appetite and inhibit microbial growth. Special groups such as children and the elderly can choose the warm mixing method of heating and cooling, which balances safety and nutrition.
