The application provides a
pet food composition for efficiently removing tear marks and a preparation method thereof, and the composition comprises marigold
powder, 0.1-5 parts;
cassia seed, 0.1-5 parts; medlar, 0.1-5 parts;
bilberry, 0.1-5 parts; blueberry, 0.1-5 parts; and the balance is a filler. The application constructs four functional target points of antioxidation, anti-
inflammation, tear duct dredging and eye
nutrition through multi-component combination, and the synergistic effect is significantly better than that of single or binary combination. The application breaks through the limitation of traditional embedding technology, realizes the trinity of "
palatability optimization +
gastric acid protection + bile protection", greatly improves the intestinal targeting release efficiency of effective components and realizes site-specific absorption, the
palatability acceptance rate is 95%, the tear mark
improvement rate is 70% in 14 days, the tear mark
improvement rate is 95% in 28 days, the effect is good and fast, and the application can be widely applied to various forms such as puffed food, baked food, wet food and health products. Long-term safety is verified by blood
biochemistry, and
