Description

Technical Field

[0001] The invention relates to the technical field of pet health food, and in particular to a highly palatable nutrient solution for companion animals and a preparation process thereof. Background Art

[0002] For most pet owners, pets are like "family members". With the improvement of living standards, the development of short video social media, and the popularization of pet care knowledge, pet owners pay more attention to the health of their pets, and their consumption in pet health care has become more diversified, which has promoted the development of the pet economy. Data shows that 85.2% of pet owners buy pet nutritional health products regularly, and 66% of users buy 2-3 times or more each quarter. They also buy health products with different functions according to the different nutritional needs of their pets. However, for many pet owners, feeding medicine is a difficult task, so "convenient feeding" and "palatable" have become the core needs of users. Liquid preparations are favored by pet owners because they can control the dosage well and are convenient for feeding.

[0003] At present, many oral liquids for pets mainly have several systems: 1. Referring to the formula design of oral liquid for human use, only nutritional needs are considered, and the palatability needs of pets are not considered, which leads to that even if there are sufficient nutrients, they cannot be fully utilized; 2. Adding synthetic meat flavors to attract the attention of pets or satisfy human sense of smell, but it has little effect on the palatability of pets and cannot improve the palatability of the product; 3. Adding commercially available powdered, liquid or paste attractants, the amount added is limited due to the properties, and for storage, these commercially available attractants will add more additives such as preservatives, thickeners, etc. to ensure their stability, which also affects the properties and stability of the final product.

[0004] The application number is 202111313634.9, which discloses a liquid attractant for spraying on dog dry food; the application number is 202211681241.8, which discloses a freeze-dried powder attractant; the application number is 201211319080.1, which discloses a spray-dried powder attractant. All three of these products used enzymatic hydrolysis and Maillard reaction processes to treat chicken livers in the early stages to reduce the bitterness of chicken livers, improve the flavor of the attractant, and achieve the purpose of improving the attractant. This is the current conventional processing method for pet attractants, but these common attractants are mainly powders or paste liquids. If a powdered attractant is used in the oral liquid, obvious precipitation will occur and the taste will be rough; if a paste liquid attractant is used, because of its high sugar or high salt system, it affects the formation and taste of the oral liquid. Summary of the invention

[0005] The purpose of the present invention is to address the defects and shortcomings of the prior art and provide a highly palatable nutrient solution for companion animals and a preparation process thereof. The nutrient solution is formed by enzymatic hydrolysis and Maillard reaction of chicken liver and blending. Based on the nutrient solution, nutrients are added according to the nutritional needs of companion animals to meet the daily needs of pets.

[0006] To achieve the above-mentioned purpose, the highly palatable companion animal nutrient solution of the present invention comprises the following ingredients in weight percentage: 30%-40% chicken liver, 0.1%-0.2% compound protease, 3%-5% yeast extract, 0.5%-2.5% reducing sugar, 0.01%-0.2% glycine, 0.3%-0.6% L-cysteine, 0.05%-0.25% thiamine nitrate, 0.01%-0.05% ethyl maltol, 5%-20% sucrose, 0%-0.05% rosemary extract, 2%-4% Polygonum multiflorum extract, 1%-2% garlic powder, 5%-10% complex vitamins, 0.1%-0.5% compound thickener, 0.1%-0.5% citric acid monohydrate, 0.1%-0.5% potassium sorbate, and 5%-30% purified water.

[0007] Furthermore, the composition of the complex vitamin and the weight proportion of each component in the total formula are: vitamin A acetate 0.3%-0.6%, vitamin E acetate 1%-2.5%, vitamin D3 0.01%-0.05%, vitamin B1 0.1%-0.3%, vitamin B2 0.01%-0.05%, vitamin B6 0.1%-0.2%, vitamin B12 0.01%-0.05%, folic acid 0.2%-0.6%, niacinamide 0.2%-0.6%, calcium pantothenate 0.3%-0.8%, and biotin 2%-5%.

[0008] Furthermore, the compound thickener comprises one or more of pectin, xanthan gum, sodium carboxymethyl cellulose, modified starch, maltodextrin, etc.

[0009] Furthermore, the reducing sugar comprises one or more of xylose and glucose.

[0010] The preparation process of the companion animal nutrient solution of the present invention comprises the following steps: Step a, chicken liver crushing: weigh the chicken liver in the formula amount, put it into a blender and crush it into chicken liver minced meat; Step b, protein enzymolysis: put the chicken liver mince into a reactor, heat it to 50-60°C, then put the protease into the reactor, close and tighten the tank cover, react for 1.5h-2h, and then the enzymolysis reaction is completed; Step c, Maillard reaction: first open the vent valve, and when the pressure on the pressure gauge is "0", open the lid of the reactor and close the vent valve, add all the weighed amounts of glycine, thiamine nitrate, L-cysteine, reducing sugar, ethyl maltol, and yeast extract into the reactor, close and tighten the lid of the reactor, start stirring, and heat up for thermal reaction; Step d, preparation: add the formula amount of sucrose, compound thickener, Polygonum multiflorum extract, garlic powder, and rosemary extract while hot, start stirring, and stop stirring after the compound thickener is completely swollen, and cool to 40-50° C.; add multivitamins, potassium sorbate, citric acid monohydrate and other ingredients in sequence, and stir until they are completely dispersed or dissolved; Step e, filtration: use a double filter to filter to prevent foreign matter and undispersed foreign matter; Step f: Packing in 100 ml glass bottles.

[0011] Furthermore, the heating temperature in step c needs to be maintained at 85° C.-95° C., and the reaction time is 1 h-1.5 h.

[0012] Furthermore, after stopping stirring in step d, the temperature is lowered to 40-50°C.
