石磨豆腐脑是利用大豆蛋白制成的高营养食品，人体对其吸收率可达92—98%。石磨豆腐脑除含蛋白质外，还可为人体生理活动提供多种维生素和矿物质，尤其是钙、磷等。老陈家石磨豆腐脑制作的过程分6步了解，如下：

Shimo Tofu Brain is a highly nutritious food made from soybean protein, and its absorption rate can reach 92 - 98%. In addition to protein, Shimo Tofu Brain can also provide a variety of vitamins and minerals, especially calcium and phosphorus, for human physiological activities. There are six steps to understand the process of making bean curd jelly by Chen Jiashi, as follows:

1、选豆：

1. Bean selection:

大豆在收割、晾晒、脱粒、装袋、贮藏、运输等过程中，会混杂进草根、树皮、泥块、砂粒、石子及金属屑等杂物。因此，在使用之前，须先把大豆中的杂物、破口豆、霉烂豆、虫蛀豆、杂豆等完全检去，再将其磨碎成豆粉。

During the process of harvesting, drying, threshing, bagging, storage and transportation of soybeans, sundries such as grass roots, bark, mud, sand, stones and metal chips will be mixed. Therefore, before use, the sundries, broken beans, moldy beans, worm-eaten beans and miscellaneous beans in the soybean must be completely removed, and then ground into bean powder.

2、选水：

2. Water selection:

生产豆腐脑需用一定量的水，水质的好坏，直接关系到豆腐脑的质量。制作豆腐脑一般以软水为宜，而深井水、溪水、矿泉水、海水等都会影响豆腐脑的出品率和质量。被工业废水污染过的湖水、水库水等严禁使用。为选择适宜的水，可用试纸测试，选用PH值5—6可产生酸碱反应的水。

A certain amount of water is required for the production of Tofu Brain. The quality of the water is directly related to the quality of Tofu Brain. Soft water is generally suitable for making bean curd, while deep well water, stream water, mineral water and sea water will affect the yield and quality of bean curd. It is forbidden to use lake water and reservoir water polluted by industrial wastewater. In order to select suitable water, test paper can be used to select water with pH 5-6 that can produce acid-base reaction.

3、滤浆：

3. Filter slurry:

把豆粉与水以1：5比例搅成糊状，倒入滤单；再把13份水多次逐渐加到单里。边加水，边搅动。直到滤出豆渣。流下的淡浆，加入锅内，即可加热煮沸。

Mix the bean powder and water into a paste in the ratio of 1:5, and pour into the filter sheet; Add 13 more portions of water to the list gradually. Stir while adding water. Until the bean dregs are filtered out. Pour the diluted slurry into the pot, then heat it and boil it.

4、制剂：

4. Preparation:

制豆腐脑的凝固剂以石膏为好。但石膏粉直接撒在豆浆中难以起凝固作用，须制成浆才能使用。制法是取用熟石膏粉三钱（每斤豆粉用量），放入盆内，加入等量水调成糊状。用手或工具仔细研磨，挤碎溶化后，添少量水进行稀释。略等片刻，颗粒较粗的石膏往下沉淀，取其悬浮液备用。反复进行多次。

Gypsum is the best coagulant for making tofu. However, it is difficult for gypsum powder to coagulate directly in soybean milk, so it can only be used after it is made into milk. The preparation method is to take three coins of anhydrite powder (the amount of soybean powder per kilogram), put it into a basin, and add the same amount of water to make it into a paste. Grind carefully with hands or tools, crush and dissolve, and add a small amount of water for dilution. Wait for a moment, the coarse gypsum will precipitate down, and its suspension will be taken for standby. Repeat several times.

5、制浆：

5. Pulping:

生豆浆过滤后经过烧煮，使残留的豆渣体积有所膨胀。因此，要把煮熟的浆再倒入滤单内，经第二次滤浆后，即可制得口感良好的豆浆。

The raw soybean milk is filtered and boiled to expand the volume of residual soybean residue. Therefore, it is necessary to pour the boiled milk into the filter sheet, and after the second filtration, the soybean milk with good taste can be prepared.

6、点脑：

6. Brain tapping:

制豆腐脑是把凝固剂倒入容器内，充分搅动后，立即把熟浆冲进去，称为反点，点后立即加盖。胀浆约10分钟后，大豆蛋白质可凝固好，即制得味美且有营养的豆腐脑。

Tofu jelly is made by pouring coagulant into the container, stirring it fully, and then pouring the cooked pulp into it immediately, which is called reverse point, and then capping it immediately. After about 10 minutes of swelling, the soybean protein can solidify well, and then the delicious and nutritious tofu brain can be prepared.

豆腐脑除蛋白质外，还可为人体生理活动提供多种维生素和矿物质，尤其是钙、磷等。特别是用葡萄糖酸内脂作凝固剂，不仅制出成品多，而且含钙量有所增加，对防冶软骨病及牙齿发育良等病有一定的功效。您有需求就来我们网站https://www.sdlaochenjia.com咨询吧！

In addition to protein, Tofu Brain can also provide a variety of vitamins and minerals, especially calcium and phosphorus, for human physiological activities. In particular, gluconate lactose is used as a coagulant to not only produce more finished products, but also increase the calcium content, which has certain effect on preventing osteomalacia and tooth development.
