Stone mill tofu machine processing tofu is a kind of green, healthy, high nutritional value green food produced by the combination of modern technology and traditional technology. In the past, the stone mill tofu was made by people or animals as the power to drive the stone mill to rotate, while the production process of modern stone mill tofu machine is combined with the machine. The machine generates power to drive the stone mill, saving time and improving efficiency. So how to store tofu?

盒装豆腐较易保存，但仍须放入冰箱冷藏，以确保在保存期限内不会腐败。若无法一次食用完毕，可依所需的分量切割使用，剩余的部分再放回冷冻室，方便下次食用。

Boxed tofu is easy to keep, but it must be refrigerated to ensure that it will not rot during the shelf life. If it can't be eaten at one time, it can be cut and used according to the required amount, and the rest can be put back into the freezer for the next time.

豆腐作为食药兼备的食品，具有、补虚等多方面的功能。一般100克豆腐含钙量为140毫克－160毫克，豆腐又是植物食品中含蛋白质比较高的，含有8种人体必需的氨基酸，还含有动物性食物缺乏的不饱和脂肪酸，卵磷脂等。因此，常吃豆腐可以保护肝脏，促进机体代谢，增加免疫力并且有作用。

Tofu, as a kind of food with both food and medicine, has many functions, such as Tonifying Qi, tonifying deficiency and so on. Generally, the calcium content of 100g tofu is 140mg-160mg. Tofu is a plant food with high protein content. It contains 8 kinds of essential amino acids for human body. It also contains unsaturated fatty acids and lecithin which animal food lacks. Therefore, often eat tofu can protect the liver, promote metabolism, enhance immunity and detoxification.

豆腐不足之处是它所含的大豆蛋白缺少一种必需氨基酸——蛋氛酸，若单独食用，蛋白质利用率低，如搭配一些别的食物，使大豆蛋白中所缺的蛋氨基酸得到补充，使整个氨基酸的配比趋于平衡，人体就能充分吸收利用豆腐中的蛋白质。蛋类、肉类蛋白质中的蛋氨酸含量较高，豆腐应与此类食物混合食用，如豆腐炒鸡蛋、肉末豆腐、肉片烧豆腐等。这样搭配食用，便可提高豆腐中蛋白质的利用率。

The deficiency of tofu is that it contains soybean protein which lacks an essential amino acid - egg yolk acid. If it is eaten alone, the utilization rate of protein is low. For example, if it is combined with some other foods, the egg amino acid which is missing in soybean protein can be supplemented, so that the proportion of the whole amino acid tends to be balanced, and the human body can fully absorb and utilize the protein in tofu. The methionine content in egg and meat protein is high, so tofu should be mixed with this kind of food, such as fried eggs with tofu, tofu with minced meat, tofu with sliced meat, etc. In this way, the utilization rate of protein in tofu can be improved.
