Description

Technical Field

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

[0002] With the continuous improvement of people's living standards and changes in family structures, more and more families in my country are keeping pets. However, due to excessive pampering and blind feeding of pets, coupled with the lack of exercise for pets kept in apartments, the problem of overweight pets is becoming increasingly prominent. Excessive fat not only accumulates under the skin, making pets intolerant to heat, clumsy, and easily fatigued, but can also lead to a variety of diseases including heart disease, diabetes, arthritis, herniated discs, and fractures.

[0003] Most pet foods on the market are puffed grains high in carbohydrates. Overfeeding and insufficient exercise can lead to obesity in pets. Currently, pet diet foods primarily use crops and plant fibers as their primary ingredients to achieve weight loss. However, long-term feeding of these diet foods can lead to essential nutritional deficiencies in pets. The present invention aims to provide a pet food that achieves both weight loss and nutritional needs. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the present invention provides a pet food for weight loss and a preparation method thereof, so that the pet food can achieve the effect of weight loss and meet the nutritional needs of pets.

[0009] Preferably, the pet food is composed of the following raw materials in parts by weight: 15 parts of konjac flour, 15 parts of egg white, 15 parts of appetizer hydrolyzed protein powder, 15 parts of chicken, 8 parts of fish, 25 parts of soy protein concentrate, 25 parts of soy protein isolate, 5 parts of fruit and vegetable powder, 3 parts of glycerin, 3 parts of hops extract, 2 parts of traditional Chinese medicine extract, 2 parts of compound premix, 1 part of probiotics, 1 part of enzyme, 1 part of black tea polyphenols, 1 part of nucifera, and 1 part of phytosterols.

[0010] Preferably, the appetizing hydrolyzed protein powder is one or more of chicken bone protein powder, pig bone protein powder, and fish bone protein powder.

[0011] Preferably, the fruit and vegetable powder is one or more of sweet potato powder, carrot powder, spinach powder, tomato powder, pumpkin powder, cabbage powder, apple powder, banana powder, and peach powder.

[0012] Preferably, the Chinese medicine extract is one or more of yam, atractylodes macrocephala, eucommia bark, codonopsis pilosula, astragalus membranaceus, and coix seed.

[0013] Preferably, the ingredients and usage ratio of the composite premix are composite trace elements: composite vitamins: Angel Yeast: glucose = 1:1:5:50.

[0014] Preferably, the probiotics are one or more of Lactobacillus, Bifidobacterium, and Clostridium butyricum.

[0015] Preferably, the enzyme is one or more of papain, alkaline protease, and pancreatin.

[0016] The preparation method of the hop extract comprises the following steps: weighing an appropriate amount of hop medicinal material powder, adding a methanol solution 30 times the volume of the medicinal material powder, ultrasonically extracting twice, each time for 2 hours, filtering and combining the filtrates, concentrating, and vacuum drying to obtain the hop extract.

[0017] The preparation method of the Chinese herbal medicine extract comprises the following steps: adding 8 times the amount of water of the original medicinal material, soaking for 1 hour, decocting for 1 hour, filtering, adding 4 times the amount of water of the original medicinal material again, decocting for 1 hour, and filtering; combining the two filtrates and placing the filtrate in a 70°C water bath to concentrate to 500 mL; adding 95% ethanol to the concentrated solution after cooling to make the alcohol content reach 65%, stirring evenly, and placing the concentrated solution in a 4°C refrigerator overnight; transferring the upper alcohol solution to a new flask, centrifuging the lower alcohol solution at 3000 r / min for 8 minutes, mixing the supernatant obtained by centrifugation with the upper alcohol solution, placing the solution in a water bath to recover ethanol and concentrating until there is no ethanol smell; adding 95% ethanol again to make the alcohol content reach 75%, repeating the above steps to concentrate the Chinese herbal medicine extract into a paste with a concentration of 6g of original medicinal material per milliliter.

[0018] On the other hand, the present invention also provides a method for preparing pet food for weight loss, which is characterized by comprising the following steps: mixing soy protein concentrate, soy protein isolate, and fruit and vegetable powder raw materials in proportion, adding 2-3 times the total amount of water of the above three raw materials, aging at 120°C for 20 minutes, cooling to 50-60°C, adding probiotics and protease for enzymatic hydrolysis for 2-5 hours to obtain a mixture A; mincing chicken and fish with a meat grinder and then grinding them with a colloid mill to obtain a minced meat mixture B; mixing the mixture A and the mixture B with the remaining raw materials, feeding them into an extruder for extrusion granulation and drying to obtain granular pet food; sieving and packaging the above granular pet food to obtain the weight loss pet food of the present invention.

[0019] The functions of some components in the weight-loss pet food of the present invention are:

[0020] Konjac flour: Konjac flour is extracted from the rhizome of the konjac plant. Its main component is glucomannan, a water-soluble cellulose. Unlike starch, glucomannan cannot be digested or metabolized by animals, so it provides a strong sense of fullness but is low in energy. Furthermore, glucomannan can accelerate gastrointestinal motility, aid in intestinal absorption, and have a laxative effect.

[0021] Hops Extract: Hops have the benefits of strengthening the stomach, promoting digestion, diuresis and calming the nerves. Hops extract has anti-tumor, antioxidant, antibacterial and free radical scavenging effects. In addition, using hops extract as a food additive can prevent food spoilage.

[0022] Black tea polyphenols: Black tea, a fully fermented tea, has recently been shown to exert lipid-lowering and weight-loss health benefits by regulating lipid metabolism, improving blood lipids, improving oxidative stress markers, and modulating intestinal flora. Black tea polyphenols, one of its main functional components, have been reported to improve high-fat diet-induced obesity by increasing the amount of short-chain fatty acids in the intestine and thereby increasing the phosphorylation of adenosine monophosphate-activated protein kinase in the liver. Furthermore, other studies have reported that black tea polyphenols can promote lipid excretion in human feces, thereby contributing to lipid-lowering and weight-loss benefits.

[0023] Nuciferine: Lotus leaf, the dried leaves of the Nelumbo nucifera plant, is both a medicinal and edible food, used in tea making and traditional Chinese medicine. Lotus leaf extract has been reported to reduce weight, blood sugar, and lipid levels, thereby promoting weight loss. Nuciferine, an isoquinoline alkaloid abundant in lotus leaves, is a key functional component of lotus leaves that contributes to their pharmacological effects.

[0024] Phytosterols: Phytosterols are an important component of plant cells and have been reported to have physiological functions such as lowering blood lipids and cholesterol, providing antioxidants, and enhancing immunity. Studies have found that consuming 2g of phytosterols per day can reduce low-density lipoprotein cholesterol levels in adults by approximately 10%.

[0025] (3) Beneficial effects

[0026] The present invention provides a pet food for weight loss and a preparation method thereof. The pet food for weight loss of the present invention is composed of 17 ingredients, including konjac flour, egg white, hydrolyzed protein powder for attracting appetite, chicken, fish, soy protein concentrate, soy protein isolate, fruit and vegetable powder, glycerin, hop extract, Chinese medicine extract, composite premix, probiotics, enzymes, black tea polyphenols, nuciferine, and phytosterols. The present invention takes into account both pet nutrition and weight loss, and the pet food formula is reasonable. Specifically, 1) konjac flour is added, which has a strong sense of fullness, low energy, and a laxative effect; 2) egg white, hydrolyzed protein powder for attracting appetite, chicken, fish, soy protein concentrate, and soy protein isolate provide high-quality protein and multiple vitamins, enzymes, and minerals, while reducing fat intake, which is beneficial to the growth and development of pet muscles; 3) fruit and vegetable powder is rich in dietary fiber and various vitamins and trace elements, which can stimulate the digestive tract to regulate gastrointestinal motility and increase immunity; 4) black tea polyphenols, nuciferine, and phytosterols can regulate lipid metabolism to achieve the effect of weight loss. The pet food has good palatability, can effectively reduce the weight of obese pet dogs, and significantly improve the abnormality of serum lipid metabolism indicators of obese pet dogs. In addition to pet dogs, the present invention can also play a weight-loss effect on pets including pet cats and pet pigs. DETAILED DESCRIPTION

[0082] Test Example 1

[0083] 1. Experimental Group

[0084] This experiment used a 9-point BCS scoring system to evaluate the obesity of Corgi dogs. A BCS score of more than 7 was considered obese. Twelve obese male Corgi dogs aged about 2 years and with a BCS score of more than 7 were selected as experimental animals and randomly divided into 3 groups, with 4 dogs in each group, namely a group fed with commercially available ordinary pet food, a group fed with commercially available weight-loss pet food, and a group fed with the weight-loss pet food of the present invention. There was no significant difference in the body weight and BCS score of the Corgi dogs in each group before the experiment. The entire experimental period was 2 months. The Corgi dogs in each group were fed in the same environment, with free access to food and water, and were guaranteed about 30 minutes of outdoor activity time per day. The changes in the average daily food intake of each group of Corgi dogs were analyzed before and after the food change, and all Corgi dogs were weighed every 2 weeks during the experimental period. After the experiment, blood was collected from all Corgi dogs to measure blood cholesterol and triglyceride indicators.

[0085] 2 Data Analysis

[0086] The experimental data were analyzed using GraphPad Prism 7.0 software and Student's t-test. The results were expressed as mean ± standard deviation, and significant differences were indicated by (P < 0.05).

[0087] 3 Results

[0088] 3.1 Palatability Analysis

[0089] The average daily food intake of the 12 Corgi dogs in this experiment was calculated before and after the experiment to analyze the palatability of the weight-loss pet food of the present invention. As shown in Table 1, there was no significant change in food intake in any group of Corgi dogs compared to before the experiment, indicating that the palatability of the commercially available ordinary pet food, commercially available weight-loss pet food, and the weight-loss pet food of the present invention was good. Furthermore, the Corgi dogs' mental state and foraging behavior were observed during the experiment, indicating that they were in good spirits and did not feel hungry or forage for food after eating.

[0090] Table 1 Food intake data of each group of Corgi dogs before and after the experiment

[0091] Group Feed intake before the experiment (g / d) Daily feed intake after the experiment (g / d) P-value Group fed with ordinary pet food on the market 165.5±6.95 167.5±5.69 0.67 Commercially available weight loss pet food feeding group 166.8±9.14 167.3±6.24 0.93 The present invention is a weight loss pet food feeding group 168.3±6.95 169.3±5.50 0.83

[0092] 3.2 Weight Analysis

[0093] As shown in Table 2, the weights of the Corgi dogs fed with the commercially available ordinary pet food and the commercially available weight-loss pet food were basically the same after two months compared with those before the experiment. The group fed with the weight-loss pet food of the present invention was fed with the weight-loss pet food prepared in Example 1. While the food intake was basically the same as before the experiment, the weight loss was 7.19% after two months of feeding, indicating that the pet food of the present invention is beneficial for pet dogs to lose weight.

[0094] Table 2 Weight data of Corgi dogs in each group before and after the experiment

[0095]

[0096] 3.3 Analysis of blood indicators

[0097] We conducted biochemical tests on the blood of Corgi dogs before and after the experiment. The results showed that compared with before the experiment, there was no significant change in the cholesterol and triglyceride levels in the serum of the group fed with commercially available ordinary pet food; the serum cholesterol concentration of the Corgi dogs fed with commercially available weight-loss pet food decreased significantly compared with before the experiment, but the triglyceride content did not change significantly compared with before the experiment; the serum cholesterol and triglyceride concentrations of the Corgi dogs fed with the weight-loss pet food of the present invention decreased extremely significantly compared with before the experiment, indicating that the weight-loss pet food of the present invention can effectively reduce the cholesterol and triglyceride levels in the blood of pet dogs to within the normal range.

[0099]

[0100] In summary, the embodiments of the present invention have the following beneficial effects:

[0101] 1. The weight-loss pet food of the present invention has good palatability, and there is no significant difference in the food intake of pet dogs before and after the food change.

[0102] 2. The weight-loss pet food of the present invention effectively reduces the weight of obese pet dogs and significantly improves the abnormalities of serum lipid metabolism indicators in obese pet dogs.

[0103] Test Example 2

[0104] To further illustrate the weight loss effect of the weight loss pet food of the present invention, an animal experiment on a pet cat is provided below for illustration.

[0105] The test animal was a golden gradient male cat that had been sterilized for one and a half years. The living environment, feeding time and feeding amount of the pet cat were kept consistent before and after the test, and the pet cat had free access to food and free drinking water. The test period was 2 months, and the weight of the pet cat was measured before and after the test. The measuring time was 10 a.m., and the calculation formula of the weight loss rate was (pet cat weight before the test-pet cat weight after the test) / pet cat weight before the test. The food intake, defecation and mental state of the pet cat were observed during the test. After analysis, it was found that the food intake of the pet cat after feeding the weight-loss pet food prepared in Example 1 of the present invention was not significantly different from that of feeding commercially available ordinary pet food. After feeding the weight-loss pet food prepared in Example 1 of the present invention for 2 months, the weight loss rate was 6.86%, indicating that the weight-loss effect of the pet food of the present invention was significant. During the test, the number of bowel movements of the pet cat was normal, and there was no phenomenon of loose stools or soft stools. Before the experiment, the golden tabby male cat was easily tired, had little exercise, was listless, and moved slowly. After the experiment, the pet cat's mental state improved and its activity level increased compared to before the experiment.
