Food-grade phosphate: Why is it called the "invisible seasoning" of the modern food industry?

Everyone knows about salt and sugar for seasoning, but few know the magic of food-grade phosphate - in meat products, it can lock in moisture to make beef as tender as morning dew; in baking, it helps flour to be fluffy like spring clouds; in beverages, it stabilizes the taste like a fixed star. It can also inhibit the growth of bacteria and extend the shelf life of pastries to more than a month. Or ask: "Is this agent safe?" Our company's products all follow international food safety standards, and after triple testing, they can be traced from the production line to the table. Today, instant noodles, ham sausages, and baked bread often contain this agent, not to add to the mix, but to use the power of technology to keep the original taste of food and keep it fresh for a long time. Isn't this the wisdom of modern diet?
