Description

Technical Field

[0001] The present invention relates to the technical field of pet food, in particular to a pet weight-loss food and a preparation method thereof. Background Art

[0002] Pet food is a nutritious food specifically formulated for pets like dogs and cats. It's a premium animal food that's a cross between human food and traditional livestock feed, primarily designed to provide pets with the essential nutrients they need for life, growth, development, and health. The main nutrients in pet food include carbohydrates, protein, fat, minerals, and vitamins. Currently, most pet food is puffed, made by mixing nutrient ingredients, puffing or extruding them into a shape, and then drying, dehydrating, and seasoning them. Puffed food is widely accepted for its comprehensive and balanced nutrition, long shelf life, ease of feeding and carrying, and affordability.

[0003] However, pet obesity caused by overeating pet food has become a major health concern for pets. Pet obesity occurs when energy intake exceeds energy expenditure, leading to excessive body fat accumulation, which in turn can cause various health problems such as diabetes, hypertension, hyperlipidemia, and arteriosclerosis. Therefore, controlling pet weight is crucial for maintaining pet health; in particular, when reducing body fat, preventing muscle loss is also crucial. While existing pet foods contain added vitamins and trace elements, these only provide limited energy and nutritional benefits. Some pet foods with weight loss claims often only contain L-carnitine, failing to comprehensively and effectively control the weight of obese pets.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The object of the present invention is to provide a pet slimming food and a preparation method thereof, which is not only beneficial for controlling the body shape of pets, but also can maintain the health of pets.

[0006] The invention provides a pet weight-loss food, comprising a basic food and a weight-loss composition. The basic food comprises a first component, and the first component comprises the following raw materials in parts by weight: 20-30 parts of fresh meat, 15-25 parts of starch, 20-25 parts of meat powder, 1-3 parts of seaweed powder, 1-2 parts of chicken liver powder, 1-4 parts of brewer's yeast powder, 0.5-2 parts of complex minerals, 0.02-0.06 parts of complex vitamins, 0.2-0.4 parts of fructooligosaccharides, 0.16-0.2 parts of taurine, 0.01-0.06 parts of betaine, and vitamin C. 0.015-0.02 parts; the weight loss composition includes the following raw materials in parts by weight: 1-2 parts of polydextrose, 0.1-0.5 parts of chlorogenic acid, 0.05-0.1 parts of yucca extract, 0.1-0.5 parts of psyllium husk powder, 0.02-0.05 parts of tea polyphenols, 0.02-0.05 parts of oligosaccharides and 0.01-0.02 parts of carnitine.

[0007] The effects of the ingredients in the weight loss composition of the present invention are as follows:

[0008] Polydextrose: It is a new type of water-soluble dietary fiber that can form a membrane in the small intestine and wrap up some food fat. It can effectively limit the absorption of fat in the digestive tract, promote the excretion of lipid compounds, increase satiety, and reduce food intake, thereby achieving the effects of regulating blood lipids, reducing fat accumulation, and preventing obesity.

[0009] Chlorogenic acid: It is an important bioactive substance with antibacterial, antiviral, white blood cell increasing, liver protecting and choleretic, anti-tumor, blood pressure lowering, blood lipid lowering, free radical scavenging and central nervous system stimulating effects.

[0010] Yucca extract: Made from the stems and leaves of the genus Yucca of the Agavaceae family, it is extracted, concentrated, and spray-dried. It is rich in yucca saponins, polyphenols, polysaccharides, and other effective substances, which can promote intestinal health, increase protein utilization, and improve animal health.

[0011] Psyllium husk powder: It is rich in water-soluble fiber, which can increase satiety and reduce calorie intake. It cannot be digested in the human digestive tract, stomach and small intestine, and is only partially digested by bacteria in the large intestine and rectum. It is used to moisturize the intestines and defecate, and it can also lower cholesterol in the body, thereby playing a role in losing weight or controlling weight.

[0012] Tea polyphenols: It is a complex of polyhydroxyphenol compounds in tea, composed of more than 30 phenolic substances. Its main components are catechins and their derivatives. It is the main chemical component in tea with health functions, and has multiple physiological activities such as antioxidant, radiation protection, anti-aging, lipid-lowering, blood sugar-lowering, antibacterial and anti-enzyme.

[0013] Oligosaccharide: It swells with gastric acid to form a gel that is adsorbed on the small intestine and combines with lipid substances such as fat, fatty acids, and cholesterol to form a complex, intercepting lipids and cholesterol in the small intestine. It has strong hydrophobicity and is not hydrolyzed by gastric acid or absorbed by the small intestine, resulting in an increase in the cholesterol content in the feces, thereby reducing the content in the serum and liver. At the same time, it can be combined with bile acid and excreted from the body. Cholesterol is mainly converted into bile acid in the liver. The reduction of bile acid in the liver promotes the conversion of cholesterol in the liver into bile acid, thereby reducing the cholesterol content in the blood.

[0014] L-carnitine (abbreviated as carnitine): is a special amino acid and a key substance in the process of fat metabolism. It can promote the entry of fatty acids into mitochondria for oxidative decomposition, which is beneficial to promoting the balance of fat metabolism.

[0015] Research has found that while a single weight-loss ingredient has a certain weight-loss effect, its efficacy is low, its duration of action is long, and its effect is not significant. While a simple combination of multiple weight-loss ingredients can improve weight-loss effects to a certain extent, the improvement is limited and there is no significant synergistic effect. The inventors, through extensive screening experiments, have developed a weight-loss composition with the aforementioned specific composition. Studies have shown that this composition can significantly improve the weight-loss efficacy of pets, rapidly reducing the weight of obese pets, thereby restoring them to a healthy physique in a short period of time. In particular, chlorogenic acid and yucca extract exhibit significant synergistic effects with polydextrose. The mechanisms of action are speculated to include: inhibiting pancreatic lipase activity, thereby inhibiting fat absorption and promoting the excretion of cholesterol and bile acids; inhibiting the body's absorption of carbohydrates, thereby preventing them from being converted to fat; inhibiting α-amylase activity, effectively controlling the absorption of carbohydrates in food and preventing them from being converted to fat; promoting fatty acid metabolism, thereby effectively breaking down excess fat and reducing fat accumulation; and inhibiting fat absorption, allowing it to directly bind to lipids and be excreted through feces, thereby achieving a weight-loss effect. Through multiple weight-loss mechanisms, the composition achieves comprehensive and effective weight control for obese pets.

[0016] Furthermore, the basic food also includes a second component, which includes the following raw materials in parts by weight: 2-4 parts of freeze-dried chicken, 0.5-1 parts of freeze-dried duck meat, 1-2 parts of freeze-dried egg yolks, 0.1-0.2 parts of pumpkin powder, 2-3 parts of beet pulp, 0.5-1 parts of celery, 0.5-1 parts of hawthorn, 0.7-0.9 parts of lysine, 0.8-1.2 parts of DL-methionine, 0.6-0.8 parts of choline chloride, 0.9-1 parts of sodium chloride and 10-15 parts of cellulose powder.

[0017] Specifically, the fresh meat can be fresh chicken; the starch can include 5-7 parts of tapioca starch, 5-8 parts of potato starch and 5-10 parts of sweet potato starch; and the meat powder can be chicken powder.

[0018] The present invention does not impose strict restrictions on the content of the weight-loss composition in the pet weight-loss food; specifically, the effective dose of the weight-loss composition can be 10-15 g / kg·BW / d.

[0019] The above-mentioned raw materials of the present invention can be obtained through common commercial purchase.

[0020] The present invention also provides a method for preparing the above-mentioned pet weight-loss food, comprising the following steps:

[0021] S1: Prepare fresh meat into fresh meat pulp;

[0022] S2: grinding and mixing the remaining raw materials except the fresh meat to obtain a raw material mixture;

[0023] S3: adding the fresh meat slurry and the raw material mixture into a conditioner for conditioning, and then performing puffing, drying, oil spraying, and cooling after conditioning to prepare a pet weight loss food.

[0024] Specifically, during conditioning, the temperature is controlled at 85-95°C and the moisture content is 10-30%. During puffing, the die head temperature is controlled at 130-140°C and the cutting frequency is 40-45 Hz. During drying, the temperature is controlled at 85-95°C and the drying time is 20-30 minutes. Furthermore, the pulverization and mixing can be performed twice: the first pulverization and mixing of raw materials other than the powdered raw materials, and the second pulverization and mixing of the raw materials with the powdered raw materials, especially those added in smaller amounts.

[0025] The pet weight-loss food of the present invention realizes comprehensive and effective body shape control for obese pets through multiple weight-loss mechanisms, greatly improves the efficacy of pet weight loss, quickly reduces the weight of obese pets, and can restore obese pets to a healthy body shape in a short period of time. It is not only beneficial to the body shape control of pets, but also can maintain the health of pets. DETAILED DESCRIPTION
