"My husband and I have a bit of allergic rhinitis. It is said that vitamin C supplementation can inhibit allergies, so there is a small bottle of orange juice at home and often drink," said Ji Ji.
The juice becomes foamy and the cap changes to a "bullet." A bottle of delicious juice turned into a "bomb." Yesterday at noon, Hangzhou's Jimmy was almost injured by a bottle of delicious orange juice.Yesterday morning, Gigi took a bottle of orange juice to drink before work. He didn't finish drinking, left a little bit (approximately 2cm) and settled on the table. At noon, Ji Ji thought it was a pity to throw it, and she wanted to pour it out.
"Just a twist, only heard a bang, and the loosened cap bounced like a bullet. At that time, my palm had not left the cap and the lid was on my hand. This article is from Chinese packaging. Bottle net. And then let go, and my palms are purple.†Look at the bottle again, it has expanded to twice the original volume, and the orange juice at the bottom of the bottle turned into a full bottle of foam.
Fortunately, Gigi's cap did not hurt.
In fact, it is not uncommon for the people to be left with the leftover fruit juice. When Ji Ji's mother posted her encounter on the Hangzhou local network, she attracted many follow-up comments.
"I also met this summer. My husband and I both like to drink that 100% juice, so I bought a box at home. That time I drank the rest of the bottle. Later that evening, I wanted to The bottle was overwhelmed, and the bottle sold for good. When it fell, it was blown off by the bottle cap. At that time, the bottle was still white smoke, and my hand was sore.
"I also encountered it. The fruit oranges were opened after a day and they wanted to be drained. They were bombed and they were scared after thinking about it."
Everyone does not want to understand: Why is this? Orange juice is not carbonated beverages, it should not contain gas Yeah?
The reporter interviewed Feng Jie, a teacher from the School of Chemical Engineering and Materials at Zhejiang University of Technology. Teacher Feng said that this is the result of fermentation. “When the orange juice is opened, the air enters the bottle. In the summer at more than 30 degrees Celsius, bacteria in the air ferment in nutrient-rich orange juice. One of the products of the fermentation is gas. The gas is suddenly released in a small space. It will explode," said Teacher Feng. "Not only that, the orange juice in the bottle has also deteriorated and cannot be drunk." But this also precisely shows that the Jiji family's orange juice is genuine and its nutrition is very rich. The bacteria fermented in a short time. According to Feng, many juice drinks have this feature.
General juices have instructions on the packaging and require the juice to be refrigerated. However, most people do not pay much attention to this issue after half a drink. "Drinking the remaining juice must be returned to the refrigerator. Because of the low temperature conditions, bacteria are not easy to ferment," said Feng.
