This invention discloses a microneedle patch and its application in braised meat products. The invention uses lactic acid, curcumin, glutamine, lacquer tree juice, hawthorn powder, kudzu root powder, hyaluronic acid, gelatin, and tea polyphenols to create an edible, soluble microneedle patch. The microneedle patch is applied to the surface of the meat to form micron-level penetration channels, then immersed in a composite functional liquid containing malic acid, glutamine, and soybean lecithin at low temperature. Next, low-salt soy sauce, braising spices, dried mushrooms, and edible porcini mushrooms are added and braised at a constant temperature over low heat. Finally, the heat is turned off and the meat is left to soak a second time to tenderize and infuse flavor, resulting in the finished product. This edible microneedle deep delivery technology solves the problems of traditional braised beef, such as tough texture, uneven flavor, high salt content, poor digestibility, and easy oxidation and browning. The resulting product is tender, delicate, low in salt, free of chemical preservatives, and easily absorbed nutrients, making it suitable for the elderly, children, people with weak digestive systems, and those prone to gout.
