Half-cooked cheese can be kept for one day at room temperature. Semi-cooked cheese is a kind of cheese cake treated by special technology, which tastes soft and waxy, light and not greasy. However, due to its rich nutrition, semi-cooked cheese is easily attacked by bacteria and other microorganisms at room temperature, which leads to its deterioration. In the production process, some preservatives will be added to the semi-cooked cheese to extend its shelf life, but these preservatives can not completely inhibit the growth of bacteria, so the shelf life of semi-cooked cheese is only one day at room temperature. Cheese, also known as cheese and cheese, is a fermented dairy product. Its properties are similar to ordinary yogurt. Both of them are made by fermentation, and they also contain lactic acid bacteria that can protect health. However, the concentration of cheese is higher than yogurt, and it is similar to solid food, so its nutritional value is richer.
