石磨豆腐腦是利用大豆蛋白制成的高營養食品，人體對其吸收率可達92—98%。石磨豆腐腦除含蛋白質外，還可為人體生理活動提供多種維生素和礦物質，尤其是鈣、磷等。老陳家石磨豆腐腦制作的過程分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、選豆：

1. Bean selection:

大豆在收割、晾曬、脫粒、裝袋、貯藏、運輸等過程中，會混雜進草根、樹皮、泥塊、砂粒、石子及金屬屑等雜物。因此，在使用之前，須先把大豆中的雜物、破口豆、霉爛豆、蟲蛀豆、雜豆等完全檢去，再將其磨碎成豆粉。

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、選水：

2. Water selection:

生產豆腐腦需用一定量的水，水質的好壞，直接關系到豆腐腦的質量。制作豆腐腦一般以軟水為宜，而深井水、溪水、礦泉水、海水等都會影響豆腐腦的出品率和質量。被工業廢水污染過的湖水、水庫水等嚴禁使用。為選擇適宜的水，可用試紙測試，選用PH值5—6可產生酸堿反應的水。

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、濾漿：

3. Filter slurry:

把豆粉與水以1：5比例攪成糊狀，倒入濾單；再把13份水多次逐漸加到單里。邊加水，邊攪動。直到濾出豆渣。流下的淡漿，加入鍋內，即可加熱煮沸。

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、制劑：

4. Preparation:

制豆腐腦的凝固劑以石膏為好。但石膏粉直接撒在豆漿中難以起凝固作用，須制成漿才能使用。制法是取用熟石膏粉三錢（每斤豆粉用量），放入盆內，加入等量水調成糊狀。用手或工具仔細研磨，擠碎溶化后，添少量水進行稀釋。略等片刻，顆粒較粗的石膏往下沉淀，取其懸浮液備用。反復進行多次。

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、制漿：

5. Pulping:

生豆漿過濾后經過燒煮，使殘留的豆渣體積有所膨脹。因此，要把煮熟的漿再倒入濾單內，經第二次濾漿后，即可制得口感良好的豆漿。

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、點腦：

6. Brain tapping:

制豆腐腦是把凝固劑倒入容器內，充分攪動后，立即把熟漿沖進去，稱為反點，點后立即加蓋。脹漿約10分鐘后，大豆蛋白質可凝固好，即制得味美且有營養的豆腐腦。

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.

豆腐腦除蛋白質外，還可為人體生理活動提供多種維生素和礦物質，尤其是鈣、磷等。特別是用葡萄糖酸內脂作凝固劑，不僅制出成品多，而且含鈣量有所增加，對防冶軟骨病及牙齒發育良等病有一定的功效。您有需求就來我們網站http://www.lincetecnologia.com咨詢吧！

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.
