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.
