Among tofu, lactone tofu is the most delicate and fragile. If you want the tofu with inner fat not to be broken, you can pack it and steam it for 20 minutes before cooking, and then cut it into various shapes according to the needs of cooking. Lactone tofu is rich in soybean nutrition and has unique advantages. It is not only lower in energy than traditional tofu, but also has a longer shelf life because it is sealed after ultra-high temperature sterilization. Coupled with the soft texture of lactone tofu, the taste is tender and smooth, and it is more acceptable, so if you have the habit of drinking milk at ordinary times and are not short of calcium, you can try lactone tofu.
