After dinner, Ye Zhenzhen took a set of popular science materials brought back from nutrition and food safety to Kexin. Pen & Fun & Pavilion www.biquge.info

I happily took the materials back to my house.

The next morning, before Ye Zhenzhen got up, Kexin came and knocked on the door.

"Knock Knock Knock ......"

A slight sharp knock on the door woke Ye Zhenzhen.

After two seconds, Ye Zhenzhen was wearing pajamas and opened the door with a hazy face, "Kexin, what's going on?

You Kexin held the information on food safety borrowed yesterday in one hand, and gestured with the other: "Now let's go to the morning market together, Zhen Zhen, you teach me how to distinguish the authenticity and quality of food on the spot." ”

"Ah?!" Ye Zhenzhen glanced up at the wall clock on the wall and complained, "Kexin, look, it's only five o'clock now." ”

"Wake up early to catch the morning market, so let's clean up and go to the big market nearby, and have breakfast outside by the way." ”

Ye Zhenzhen looked at You Kexin who was standing at the door of the room, and her face was excited, even more excited than when the two of them were going out shopping together in college.

"I can't help it. Ye Zhenzhen compromised, "Okay, go early and come back early, at eight o'clock, I have to go back to the downstairs of the Xincheng apartment to take the unit's shuttle bus to work." ”

Seeing that Zhen Zhen agreed, You Kexin looked happy and said with a smile: "No problem, we have more than two hours, and we won't be delayed." ”

The two of them packed up and were about to go out, Ye Zhenzhen suddenly noticed that something was wrong, thought for a while, and asked, "Where's Auntie? Kexin, where did your mother go? I haven't seen her this morning, usually, Auntie gets up very early." ”

You Kexin: "My mother, I've gone out early." ”

"Where are you going?"

"Big market, my mother went out at half past four, she said, it's summer, it's dawn early, she can't sleep, so she gets up early, and the vegetable farmers and vendors near the big market get up very early, and the stalls have begun to come out at half past four, I really can't get up, so I slept for half an hour. ”

"Oh, I thought Auntie would want to come with us. ”

"My mom wanted to come with us, but she said she was going too late and the new stuff was picked up. ”

Ye Zhenzhen smiled, "Let's hurry up too." ”

――

The "big market" in the mouth of the heart is a commercial street, only ten minutes' walk away from the new city apartment, the commercial street is lined with shops, the business types are varied, and there is a separate area demarcated, which is used to sell vegetables, melons and fruits, aquatic products, poultry eggs, meat and its products, soy products, cooked food, condiments, native products and other agricultural products and foods, mainly retail operations, this area is also called the farmers' market.

In BJ City, with the increase of hypermarkets, shopping malls, specialty stores, fresh supermarkets, and convenience stores, there are fewer and fewer farmers' markets like this.

This farmer's market near the New Town apartment is bustling with business, especially in the morning, and it can be described as a crowd.

Ye Zhenzhen and You Kexin crowded into the farmers' market with the flow of people.

You Kexin stopped in front of a shop selling marinated products, the shop area is not large, and through the glass window, you can clearly see all kinds of marinated products inside, including marinated pig's head, pig's ears, pig's feet, pig's liver, and meat skin jelly.

Ke Xin glanced at the various marinated goods a few times, and finally his eyes fell on a square piece of meat skin jelly, "Zhen Zhen, look, could this meat skin jelly be added with industrial gelatin?"

Kexin asked this, and Zhen Zhen remembered what had been mentioned in the information, some unscrupulous traders, in order to improve the shape of the jelly of the meat, Reduce costs, add industrial gelatin, but the practice of industrial gelatin is to collect low-cost leather scraps, through a series of processes, the hydrolyzed protein from the leather is removed, to make gelatin, which can effectively use waste leather and reduce costs, however, the problem is that waste leather contains a lot of metal chromium residue in the leather tanning process, and in the process of removing hydrolyzed protein, chromium can not be removed cleanly, so industrial gelatin is toxic.

Looking at Ke Xin standing in front of the marinated goods stall, with a suspicious look, Ye Zhenzhen explained: "The real meat skin jelly is an easy to melt food, which is not easy to solidify and not easy to store when it is hot. ”

You Kexin opened the small door of the window, leaned forward, sniffed it, and whispered, "It smells like meat." ”

Then, You Kexin picked up the disposable thin plastic PE gloves next to him, put them on his hands, and carefully pinched the meat skin jelly with his thumb and index finger, but did not crush it, "I didn't crush it, is it that I don't use enough strength?"

Kexin also wanted to increase her strength and pinch it again, but Ye Zhenzhen pulled her behind her and reminded in a low voice: "Kexin, it's enough, the stall owner is watching you." ”

You Kexin raised his head and met the gaze of the stall owner.

The stall owner has been observing Kexin for a while, since the two of them came to the stall and muttered, the stall owner felt that the two of them did not look like buying things, and now, seeing You Kexin look at it with a critical eye, pinching and pinching, the stall owner's face was even more ugly.

The stall owner asked impatiently, "Do you buy anything or not?"

You Ke withdrew his hand in disgust and said, "Of course, you have to pick it before you buy it." ”

The stall owner: "What's so picky about this? The pork skin jelly is a whole piece, how many do you want? I'll cut it for you." ”

You Kexin was silent for two seconds, and suddenly asked, "Boss, is there any industrial gelatin in your meat skin jelly?"

The stall owner was stunned for a moment, and soon, his face sank, and he scolded: "You little girl, you look very cute, but why is it so ugly, my shop has been open for five or six years, and all the customers who come here are old customers, and my marinated goods are all original, without any additives, little girl, you have to be responsible for what you say, you can't ruin the reputation of my store like this......"

The stall owner said as he walked out, seemingly trying to find Kexin's theory to the end.

Ye Zhenzhen pulled up Kexin and ran, and before running, she threw a sentence at the stall owner: "Boss, I'm sorry, we won't buy it." ”

You Kexin was pulled away by Zhen Zhen, there were many people in the market, and the stall owner took care of the business and did not follow.

The two of them didn't stop until they ran back and couldn't see the marinade store.

You Kexin ran out of breath, and after stopping, he asked, "Zhenzhen, why are you pulling me away." ”

"If I don't pull you away, will you wait for you to be beaten by the stall owner there?"

"How can a stall owner beat someone? I just want to ask a few questions. ”

"Ask a question, Kexin, you don't look at where this is, the farmer's market, all the people who come here are uncles and aunts who buy vegetables, when you ask this, people will think that there is a problem with the marinated goods store, who would dare to buy it?"
