Vietnamese fresh spring rolls were found to have compounds that kill harmful bacteria in food. Photo: RMIT. Professors and researchers at RMIT University (Australia) have shown how to use this natural bacteria-killing compound to keep food fresh for longer. Weapons to kill bacteria A team of researchers from RMIT University was inspired to learn about the potential, antibacterial properties of Nem chua after traveling to Vietnam. They were surprised to see people who ate this raw meat without getting sick even in hot and humid climates. The research team, led by Professor Andrew Smith (Griffith University, Australia) and Dr Bee May, has discovered a new type of germicidal compound in spring rolls. That’s Plantacyclin B21AG, a group of compounds made by bacteria to kill other rival strains of bacteria. This compound is said to be much more potent than previously created man-made preservatives as food preservatives. The harmful bacteria Listera (green) dies after being exposed to the compound in Vietnamese spring rolls, Plantacyclin B21AG. Plantacyclin B21AG can survive at 90 degrees Celsius for 20 minutes and remains stable at high or low pH levels. This compound has the ability to kill a wide range of pathogenic organisms commonly found in food, Listeria, potentially life-threatening, persisting in the refrigerator or even when frozen. Study co-leader Professor Oliver Jones said there was a growing need for natural alternatives to artificial food preservatives. The reason for this is the change in people’s consumption habits. Safe for humans Professor John, associate dean of the Department of Food Science and Technology at RMIT University, said: “Scientists have known this natural bacteria-killing compound for many years. But the challenge was to manufacture it. obtain them in quantities large enough for use in the food industry”. “The structural compound of Nem chua is colorless, odorless, tasteless and very tough. Through this new study, we have identified suitable growth conditions that allow us to produce this compound in large quantities. large, potentially industrial scale. I hope this is an effective, safe and natural solution to both waste and potentially food-borne diseases,” said Professor John. Australian professors and doctors were surprised that spring rolls made from raw meat are not harmful to people. Photo: Vietnamdiscovery. Dr Elvina Parlindungan, who completed the study, said: “Using natural bacteria themselves as effective preservatives in food, we are turning bacteria’s toxic weapons against them. This smart solution from nature will solve all the major challenges in food technology. In the future, these compounds could also be useful as antibiotics in medicine.” Following the discovery, researchers at RMIT University began testing methods for purifying the compound and are planning to include it in experimental products. They look forward to working with many potential industry partners to further develop food technology. This work was supported by a PhD scholarship from the Indonesian Education Foundation (Indonesian Ministry of Finance), awarded to Dr. Parlindungan.

Normally, the skin of the face is the thinnest area on the body, especially the thinner the skin around the eyes, so staying up late, crying, and being angry can cause swelling around the eyelids. The outermost layer of skin (the horny layer) is where cells die and are replaced by underlying cells. It contains moisturizers for the skin, helps soften the skin, keeps it moist, and is a place to directly show skin health. As we age, the rate of change in the horny layer decreases. For example, baby skin changes every 14 days. When we are 20 years old, our skin changes every 28 days. When we are 40 years old, our skin changes every 50 days. Therefore, to have skin beautification and rejuvenation, skin needs to be changed faster, but of course at a moderate rate with the age of the body. A mask is one way to increase skin moisture and increase the exfoliation of dead cells. Any mask with a moisturizing effect or lotions can do this well. With coffee masks, like other masks, it has a moisturizing effect when applied, so it will have some certain effects. But to date there are no studies showing that coffee beans reduce eye fatigue or whiten skin. There are also no studies showing that coffee masks can improve hair. The danger point is the preservatives and impurities in the coffee powder. You should remember ground coffee powder to drink should have all the five flavors including oil, corn kernels, preservatives … not to mention honey (germs and impurities). At the same time, everyone has a different skin type (oily, dry, mixed, ..) so there will be different types of masks for each person, not everyone will be good with coffee masks. Before using any product, you should thoroughly understand whether it is natural but sometimes not necessarily safe, especially when using these ingredients to beautify the skin, as it can cause side Effects.

What is water?

Soda is a beverage that typically contains saturated carbon dioxide water, a sweetener, and is often flavored. Some other carbonated soft drinks also contain caffeine, colorants, preservatives and other ingredients.

Soda is considered a vitamin and mineral supplement, widely marketed for improvements in human dehydration, lack of energy and mental fatigue.

The ingredients are in boiling water

– The most basic material of water is water, usually purified water with different levels depending on water treatment technology and equipment. If not, the product will be cloudy, sedimented, and contaminated with microorganisms.

– Sugar or sweetener is often called “folk” as a chemical sugar. They are also nothing to replace in manufacturing products for people with a history of diabetes.

– Flavors: most soft drinks have artificial flavors with different levels to create a natural-like aroma, creating a pleasant feeling. There are two levels: used for industrial production and used to produce in food.

Illustration.

Food coloring is a must for soda manufacturers. It helps the beverage to have a beautiful color and appeal to the eyes of consumers more.

Preservatives are necessary in every beverage bottle because soft drinks contain sugar and some potentially spoiled nutrients. The preservative will prolong the shelf life of the product. However, they are only allowed in a certain amount.

– Finally, there may or may not be C02. C02 carbonated soft drinks are easy to feel when drinking, but for many people, especially those with problems with the digestive system, this substance can cause unpleasant satiety or some harm.

Drink soft drinks to help quench your thirst

Soda or carbonated soft drinks are drinks that are quite popular on hot summer days. Many people like to drink carbonated soft drinks because it helps to cool down quickly and refreshes the drinker immediately.

However, according to Assoc.Prof.Dr. Nguyen Xuan Ninh, Head of the Clinic of Nutrition, Institute of Medicine that applies the refreshing feeling of carbonated soft drinks is only instantaneous and it will quickly cause thirst. later.

To explain more about this, this expert said that the feeling of thirst after drinking carbonated soft drinks is because the carbonated soft drinks contain CO2 and water (H2O), these two substances when entering the body will create. a reaction together produces a weak carbonic acid.

“Carbonic acid can stimulate the taste receptors in the mouth, plus the use of water when cold will bring a feeling of refreshing, quenching.” In fact, carbonated soft drinks can only quench your thirst. Just a few minutes after drinking carbonated soft drinks will cause more thirst. The reason is that the sugar in carbonated soft drinks is high and the sugar is quickly absorbed. High blood sugar, the brain will signal to trigger a feeling of thirst and notify that you need to drink water to bring the blood back to a normal state ”, Assoc.Prof.Dr. Xuan Ninh.

Misuse of carbonated beverages is potentially dangerous

Carbonated soft drinks provide fast energy, but the main energy is empty energy that is not beneficial for the body, young children drink too much carbonated soft drinks can lead to excess energy, obesity. Children who drink a lot of carbonated soft drinks will lead to a lack of nutrients because they will reduce other healthy drinks for example (milk, juice).

Associate Professor, Dr. Ninh recommends: “In carbonated soft drinks, which contain a certain amount of caffeine, when children drink a lot, they will cause central nervous system stimulation. Too much caffeine can cause the following conditions (in both adults and children): restlessness, upset stomach, headache, difficulty concentrating, difficulty sleeping, increased heart rate, increased blood pressure, loss of urination ” .

Carbonated soft drinks contain a lot of phosphorus if used too much, leading to an excess of phosphorus. Excess phosphorus will affect the absorption of iron, calcium, magnesium and zinc. Phosphorus poisoning leads to diarrhea, hardening of organs and soft tissues, increasing the risk of chronic bone, kidney and cardiovascular diseases.

Associate Professor, Dr. Ninh said that to use good carbonated soft drinks for the body for adults, do not drink more than 3 cans / week, children 1 can / week, children under 2 years old do not drink sugary drinks. If you want to drink in the summer, you can choose other healthier drinks such as water or juice. For water, you can add a few slices of lemon or mint leaves for more flavor.

Drink beverages properly and effectively

Here are some tips for quitting your habit and reducing your risk of the negative effects described above.

Don’t give up right away

If you are drinking more than one can per day, it will be nearly impossible to quit immediately. Instead, cut in half and gradually reduce your intake over the course of 2-4 weeks.

Replace your favorite drink

Readers try to replace soft drinks with another drink that does not contain sugar or sweeteners. For example, try herbal tea, mineral water squeezed with a piece of fresh lemon, or a glass of milk to quench your thirst.
