In our daily lives, we often eat tofu when we eat, right?
It is even said that some friends who have lived in the countryside often go to the workshop to make tofu with soybeans at home, but is tofu really only a raw material of soybeans?In fact, a type called "aokako" can also be used as a raw material for tofu.
Are you very unfamiliar with this name?,Actually, I haven't heard of it before because of my age.,But after some understanding, I understand why things that were once used as staple foods are now unpopular!
The green oka fruit, also known as the green oka fruit, is a fruit produced by a large tree.
According to historical records, the green oka fruit has a long planting process in China, its shell is extremely hard, but the flesh is very sweet. In some places, people grind the green oka fruit into a powder and make it into a variety of delicacies.
The appearance of this fruit is actually very interesting, it is usually nut-shaped or oval-shaped, and the ripe green oka fruit will be covered with a hard skin on the buttocks, and the navel protrudes to look like a spinning top, so it is also called a spinning top.
Readers who lived in the village as children may know the spinning top, and many people would pick the fruit and play with it as a toy when they were children, and sometimes beat the spinning top with a rope to make the fruit spin at high speed, just like a spinning top.
It can be said that the spinning top should be a childhood memory for many people.
This kind of tree grows very tall and usually more than ten meters high, and the highest one is more than 20 meters, which is equivalent to seven or eight floors, which is very scary. The stems of the trees are very thick and long, some of which are even hundreds of years old.
They bloom in April and May, and their fruits do not ripen until October.In many books in ancient China, there are records of eating green oka, but green oka has a small poison, and if you eat too much, you will not digest, that is, it will be difficult to defecate.
If you eat it directly, it has a crisp taste, but it tastes slightly bitter and is not delicious when eaten raw. You can also cut the peeled green oka fruit into small pieces and eat it directly or add it to porridge, soy milk, drinks and other foods. If you prefer a softer texture, you can put it in a pot and bring it to a boil with water, and then simmer for a while.
Qinggang is rich in nutrients such as fat, protein, carbohydrates, vitamins, etc. Moreover, the green carp contains a certain amount of fiber, which may be difficult for people with weak digestive function.
However, although green oka is rich in nutrients, it is still necessary to eat it in moderation.
It can be said that the whole body of Qinggang is a treasure, its leaves are dense, and it is windproof and fireproof, it has tall trees, well-developed root system, and can also prevent soil erosion.
In addition, the wood of the green oka tree is also very tough, not easy to be corroded, often the preferred material for furniture and wooden tools, and even it can be used to make carbon, the carbon it burns, very resistant to burning, is a very high-quality carbon.
At the same time, the green oka tree is also one of the most widely distributed tree species in China, and there are traces all over the country, especially in places such as hillsides or valleys, there are always one or two green oka trees standing in the wind.
In ancient times, when food was very scarce, Qinggangzi was an important living food for people at that time.
There is a record in Han Feizi's book: "Qin is hungry ......."Acorns, enough to liven the people, please send them". It's hard to imagine that in the past, acorns were one of the staple foods.
When there is a shortage of food, winter acorns are particularly important for the common people, acorns are rich in oil and starch, and can play a very important role in the winter of hunger and cold, and mountain people will go to the mountains to collect acorns and make all kinds of fresh food.
At that time, it was actually a very difficult job to collect green okazi, and the mountain roads were bumpy in the cold winter. Because the trees grow very tall, it is completely impossible to climb the tree to pick the fruit, so it can only fall naturally when the green tree is ripe.
In the bitterly cold season, the mountain people have to carry large baskets on their backs, wade through mountains and rivers to the area of the green oka tree, and pick up fruits under the green oka tree, just to have enough food to survive the winter.
Fortunately, the yield of this fruit tree is also very high, a tree can bear hundreds of catties, and there are still many people who carry the green gangzi from the mountains to the home land in winter.
After the mountain people have picked the green oka, how should they eat it?The starch content of Qinggangzi is very rich, but the taste is very astringent when eaten raw, and it is poisonous when eaten raw.
But at that time, the wise working people were not stumped by Qinggangzi, and also discovered the wonderful way to eat Qinggangzi, to eat "good" Qinggangzi, it was necessary to go through continuous drying, washing, and steaming.
At that time, people could process green oka seeds into various foods to satisfy hunger, such as acorn noodles, acorn flour, acorn tofu, etc. Grinding the green oka into flour and then mixing it with water to form a dough can be made into acorn noodles, which are used to make various pasta dishes, such as noodles, dumpling wrappers, etc. Grinding green oka into a fine powder, that is, acorn flour can be used to make various pastries, biscuits, etc.
Grinding the green oka into a pulp and then adding a coagulant can make the green oka tofu, which is highly nutritious and a healthy food.
Qinggangzi tofu has a delicate taste with a certain bitterness and astringency, while other tofu has a softer texture and a light taste.
In addition, Qinggangzi tofu is rich in protein, fat, carbohydrates, vitamins and other nutrients, and has high nutritional value.Other tofu is also rich in protein, calcium, iron and other nutrients, but compared with Qinggangzi tofu, its nutrients are relatively simple.
In the past, people would also use Qinggangzi to feed pigs, and when people had food to eat, they would break it up as pig feed, because its starch content was quite high, and piglets could eat more starch to become fat and strong.
Qinggangzi was really popular in the past, but now Qinggangzi is almost unpopular, and it is rare to see Qinggangzi's derivative products on our table, and even when it comes to Qinggangzi, many people don't know it.
In the past, everyone liked to eat green oka because the economic conditions were not good, and it was often the age of not having enough to eat, so they would go up the mountain to pick this kind of small fruit that was everywhere but it was more troublesome to pick, and now everyone's economic conditions are better, and few people are willing to spend so much time and energy to collect green oka.
What's more, the processing process of Qinggangzi is also very complicated, and it takes many layers of processes to become easy-to-eat raw materials, and from the perspective of industrial processing, it is actually very cost-effective to use Qinggangzi as raw materials. Now if you want to eat starch, potatoes, corn, etc. are good starch raw materials.
And Qinggangzi is actually not very delicious in taste, the taste of raw Qinggangzi is too poor, and there are slight toxins, in the fast-paced modern life, even if Qinggangzi is rich in nutrients, everyone is not willing to eat. Over time, Qinggangzi became the tears of the times.
Many children living in rural areas may have seen Qinggangzi when they were young, but even if they do, they are more often just used as toys, that is, the spinning top we talked about before, and you can tell the way to play with a rope or a tree branch.
Now is the era of a mobile phone in everyone's hand, the entertainment activities on the mobile phone are complicated, and all kinds of novel gameplay are flooding everyone's life, under such conditions, the spinning top has become less attractive.
Even children in rural areas have begun to get in touch with the Internet, and they still prefer online games to such simple toys.
In any case, Qinggangzi still carries a lot of historical memories, in the past it fed a lot of poor mountain people, it is the main food that many people rely on to survive**, and it is also the childhood memories of a generation.
Although we no longer need Qinggangzi so much, we should not forget the value of Qinggangzi, and it is precisely because of its contribution that we have a good life now.
