Chapter 619 :The difference between soy milk and oil extraction

“Okay, leave it to me.” Chu Feng took the bean cakes handed over by the girl and put them into the trough of the oil press one by one.

He then stuffed it into the deed, and then slowly knocked the wooden deed into the gap of the trough with the prepared wood.

“Tick Tick Tick Two Two”

Following Chu Feng’s movements, one head of oil was slowly squeezed out, and dropped into the clay pot along the bamboo trough under the oil outlet.

The girl quickly moved the second batch of six beancakes. Put it on the head next to the oil press.

“Well, everyone, don’t worry, the bear’s paw should be ready, let’s have some lunch first.” Chu Feng stopped his hand and said.

“Okay.” Everyone replied, and they all went upstairs after washing their hands by the stream.

“It smells good 1 2 but I don’t know how it tastes?” Chu Feng lifted the lid on the clay pot, and the soup that was originally filled appeared

There are only a few left, just barely past the bear’s paws

He thought for a while, added some oyster sauce to the pot, and put the pot on the table after the fire closed.

“The color looks good, and I didn’t smell the fishy smell.” Liu Yimeng snorted and commented, lying on the wooden table.

“Taste it.” Chu Feng raised his brows-he said.

“Okay.” Liu Yimeng picked up the chopsticks and gently-poke the soft bear’s paw. It is easy to pick up a piece of bear paw meat and send it to

I blew around my mouth, then stuffed I into my mouth and chewed

She chewed twice, and then exclaimed, “It melts in the mouth, there is no fishy smell at all, it’s delicious.”

“Really? I’ll try it.” Yun Xin stretched out his chopsticks, and then Liu Yiqiu picked up a piece of palm meat and tasted it.

Yun Xin praised, “Really delicious.”

“Well, this is the correct way to eat bear meat.” Liu Yiqiu nodded in agreement.

“How to do this 3 Anna must be very interested.” Li Youyou asked, turning his head in awe.

“It’s very simple, just watch the live broadcast.” Chu Feng raised his hand-pointing to the camera placed on the wooden frame.

“I’m afraid I will wait for you to send her the meat.” Yun Xin chuckled softly, covering her mouth.

“Don’t tell me, it’s possible.” Li Youyou followed and laughed.

“By the way, can you give me two pieces of meat at that time, for Sister Qingyue and Sister Wei Ting?” Yun Xin thought of Shi Ma and said in a hurry.

“No problem, but I don’t know how to contact them?” Li Youyou = agreed.

“Sister Qingyue will find you somehow, don’t you think 2” Yun Xin blinked at the camera.

In the observer’s live broadcast room, Wu Qingyue couldn’t help but chuckle.

“It’s still a little Lolita who can be a human being.” She smiled and said.

“Ahem, shouldn’t the good things be brought out and shared by then 2” He Ming half joked.

“Want to eat?” Wu Qingyue looked at He Ming with a smile.(Read more @ wuxiax.com)

“Uh, I don’t want to.” He Mingyan fish pump 2″ Wang Lin put his mouth on his mouth directly. Although he was curious about the taste of bear meat, face was more important.

“Don’t worry, when I follow the method taught by Chu Feng, I will bring you a taste.” Wu Qingyue waved his hand.

“This feeling is good.” He Ming laughed 2

“It’s still unfinished.” Yun Xin couldn’t help but licked the soup that I accidentally stood on her upper hair finger.

“Do you still want to eat?” Chu Feng asked indulgently

“Well, but I shouldn’t gain weight?” Yun Xin nodded and shook his head.

“How can I gain weight if I only eat this little bit?” Chu Feng said amusedly

“That said, bear paws don’t have much meat,-a few dollars is gone.” Yun Xin nodded thoughtfully.

“Then give someone who can hold back tonight.” Chu Feng raised his hand and pinched the girl’s fleshy face. The girl is really a little bit.

The flesh is growing. It looks more cute and beautiful 2

“Well, let’s cook some arrowroot noodles. That’s the decision for dinner today.” Yun Xin nodded and responded with a smile.

“Uh. Aren’t you tired of eating arrowroot?” Chu Feng asked with a wry smile.

“No, arrowroot is so delicious, it can still be.

,” Yun Xin said with a pretty face red, some inexplicably white-,

Take a look at Chu Feng-

“Did I say something wrong?” Chu Feng muttered to himself somewhat puzzled.

Liu Yimeng smirked and went downstairs, eating and drinking enough to work.

With the tacit cooperation of everyone, the remaining oil-sand beans are made into bean cakes, which are squeezed with first oil, stir-fried again, and pressed by the house.

The three steps of squeezing have completed the full utilization of the oil sand beans.

Time also came to around four o’clock in the afternoon unknowingly.

The sisters of the Liu family, Xiao Yiyi, slowly moved the clay pot with vegetable oil into the wooden house. Placed in the corner of the wooden house.

The oil-sand-beans 1 planted this time squeezed out three pots of vegetable oil, enough for four people to eat until the end of the game. Also get twenty

Many pieces of beancake can be eaten as market food.

“My hands are getting cramped.” Liu Yimeng shook her little hand and rubbed the oily beans for z days, feeling that the hand is no longer his own.

“I’m a bit puzzled, why don’t you use the stone mill you did last time to squeeze oil?” Li Youyou asked curiously.

“Of course not. That way, you can only squeeze soy milk, not oil. As for the principle, I don’t know.” Liu Yimeng shrugged



Shrugged that he didn’t know.

“This is a good explanation to use soybeans as an example. Stone milling can only grind soy milk, but after cooking and pressing it can produce soybean oil.” Chu Feng used plain and easy-to-understand words to popularize science.

Take soybeans as an example. Soybeans are also called soybeans. 2 It contains about 20% oil, 3.6% protein, and 30__,

% Carbohydrates.

In soybeans, these oils are divided into small oil droplets, and the surface of these oil droplets are covered with z = layer of phospholipid protein structure.

The resulting membrane is also called ‘oil body membrane protein’.

‘Oil Body Membrane Protein’_ is very hydrophobic, and they are closely related to each other. Can form a film on the surface of small oil droplets, making

The oil droplets don’t break, just like tossing 1-For example, crushing soybeans and boiling them can’t destroy this layer of film.

This is the reason why stone mills can only be used to grind soy milk but cannot squeeze oil.

It is precisely because of the strong hydrophobicity of “oil body membrane protein” that heating the soybeans reduces the viscosity of the oil and makes the surface of the oil droplets

The stability of “oil body membrane protein” decreases, and pressure is applied to the soybeans to squeeze that layer of “membrane” to squeeze out the oil.

“Understand?” Chu Feng looked at the four women and smiled.

“I understand.” Yun Xin nodded thoughtfully.

“Me too.” Liu Yiqiu pursed his lips and nodded.

“What are you talking about? 2 How come I don’t understand at all?” Liu Yimeng’s expression was a bit dull, as if he couldn’t figure it out.

child.

“Sure enough, you are not the material for reading.” Liu Yiqiu sighed–said.

“What?” Liu Yimeng pursed his lips and asked without giving up, “Yoyou, do you understand?”

“Well, I understand.” Li You You nodded earnestly.

“” Liu Yimeng pouted and walked away silently, the feelings since 2. do not understand.
