What is "terrible" golden staphylococcus frozen dumplings?

Following the thoughts and trifecta, Wanchai Ferry was also involved in the bacteria gate. "Deep-fried dumplings in the end can not eat?" 39 editor for this interview with our country's leading nutrition expert, senior nutrition expert in the Guangzhou Military District Center for Disease Control Professor He Yingqiang. Let us listen to what the experts say.

What is Staphylococcus aureus?

S. aureus is widely found in natural environments such as air and soil and is a common aerobic microorganism. On the one hand, Staphylococcus aureus may cause the body to be infected with pathogenic bacteria, resulting in people suffering from some infectious diseases, such as otitis media, purulent body, etc., and it may cause lice on the skin; on the other hand, golden yellow grapes The cocci may also cause toxins in the human body. Toxins can reach a certain amount and may cause food poisoning.

Humans and animals are the main carriers of bacteria, and about 50% of healthy individuals have this bacteria in their nose, throat, hair, and epidermis. It is internationally recognized that the concentration of bacteria that produce staphylococcal enterotoxin is greater than 100,000/g. Staphylococcal enterotoxin poisoning can cause severe nausea and vomiting, accompanied by abdominal cramps and diarrhea. Severe cases can lead to collapse, intestinal spasm and severe water loss.

"Three Passes" kills Staphylococcus aureus

First pass: boiled for 5-10 minutes

Asked that the bacteria on the Internet need to be “heated to 80°C, can be killed in 30 minutes, and dumplings have been boiled for a long time”, Prof. He thinks this is correct, but there is a best of both worlds: “You can put Cook in boiling water at 100°C! Cook for 5-10 minutes and the vast majority of Staphylococcus aureus is killed."

Professor He pointed out that most of the "pus and long mustard seeds" are caused by Staphylococcus aureus, but the bacteria have a fatal weakness: they are afraid of heat and are afraid of hot. "It's most effective to use boiled water, so don't eat raw, or It's not OK to cook it in a hurry."

The second pass: stomach acid is a natural barrier in the body

After the first pass, 95% of Staphylococcus aureus has been killed. In addition, some stubborn people will survive. But don't worry, when the dumplings are chewed and swallowed into the stomach, they have to pass the "acid" barrier. The acidity of stomach acid is very high, "It is very easy to eliminate this kind of bacteria by the acidity of stomach acid.

The third pass: garlic, vinegar mixed with food, but also sterilization

“The staphylococcus aureus in the quick-frozen dumplings can be safely consumed through the first two passes,” Professor Ho added. If you still don’t feel at ease, you can put some garlic, vinegar, and other bactericidal condiments while eating dumplings. This adds yet another protective barrier.

Polyhydroxybutyrate PHB

PHB is a truly biodegradable and biocompatible plastic and an attractive environmental-friendly alternative to fossil-based thermoplastics such as PE and PP. However, unmodified PHB resin has a relatively high melting point of about 160 to 180 °C and is difficult to process due to its narrow processing window. To improve its processability and mechanical properties, PHB is often blended with plasticizers and other polymers such as polyvinyl acetate (binders), polyvinyl alcohol and polylactic acid (PLA).

Commercial grades of PHB have properties that are very similar to those of polypropylene (PP). Typical applications of PHB are disposable tableware articles like drinking cups, cutlery, trays, food plates and food containers. Some other (potential) applications include soil retention sheething and other agriculture films, waste and shopping bags, and the use as a packaging material in general. PHB can also be spun into fibers which could be used for the manufacture of woven and non-woven biodegradable one-use fabric articles such as surgical sutures (Tepha). Other (potential) biomedical applications include drug delivery systems (microcapsules or microspheres) and biodegradable implanted medical devices.
