Description

Technical Field

[0001] The present invention relates to the technical field of food, and particularly relates to a complete nutrition formula food and a preparation method thereof. Background Art

[0002] Special medical purpose formula foods are formula foods specially processed and prepared to meet the special needs of nutrients or diets for people with restricted eating, impaired digestion and absorption, metabolic disorders or specific disease states. Such products must be consumed alone or in combination with other foods under the guidance of a doctor or clinical dietitian. Complete nutrition formula foods are special medical purpose formula foods that can be used as a single source of nutrition to meet the nutritional needs of the target population.

[0003] High body metabolism generally refers to the resting energy consumption of the body being more than 10% higher than the normal value. Body infections, multiple traumas and burns can all lead to a hypermetabolic response. During a hypermetabolic response, skeletal muscle breaks down excessively, and the breakdown rate of muscle protein far exceeds the synthesis rate, resulting in a burden imbalance. There are many causes and complex mechanisms of hypermetabolism. The body's consumption increases while utilization is insufficient, and rapid weight loss is an important reason among them. Sufficient nutritional supplementation can offset the body's consumption, rebuild the composition and metabolic homeostasis of a normal body, contribute to the repair of the body, and ultimately improve the cure rate and the quality of life of patients after recovery.

[0004] Severe burns not only cause damage to the full-thickness skin, muscle tissue and bones, but can also directly or indirectly damage multiple systems and organs throughout the body such as the heart and kidneys. Myocardial injury is the most serious injury in patients with severe burns. Severe burns will cause the patient's body to have a persistent hypermetabolic response. If not corrected in time, it will delay the wound healing process of the patient, increase the risk of infection, and even cause multiple organ failure or death. Standardized enteral and parenteral nutrition is an effective means to deal with the hypermetabolic response after severe burns, which helps to improve acute malnutrition caused by burns, accelerate wound healing, and reduce the infection rate and mortality rate. The Adult Burn Nutrition Support Guidelines indicate that protein is required for burn wound repair, and a nutrient solution with a high nitrogen / calorie ratio is needed. Early enteral nutrition short peptide preparations after burns are more beneficial than whole protein preparations in increasing visceral protein levels and reducing diarrhea. The energy density of traditional complete nutrition formula foods is lower than 1.2 kcal / mL, and they cannot well meet the special nutritional needs of the severe burn patient population. Summary of the Invention

[0005] The present invention provides a complete nutrition formula food and a preparation method thereof to solve the problem that the energy density of traditional complete nutrition formula foods is insufficient and cannot well meet the special nutritional needs of the hypercatabolic patient population.

[0006] The present invention provides a complete nutrition formula food, comprising the following components in parts by weight: 7 - 13 parts of protein, 3 - 8 parts of fat, 16 - 30 parts of carbohydrates, 0.1 - 0.5 parts of compound vitamins, 0.8 - 1.5 parts of compound minerals, 0.5 - 1.5 parts of fructooligosaccharide, 0.1 - 0.2 parts of calcium β-hydroxy-β-methylbutyrate, 0.04 - 0.06 parts of mono- and diglycerides, 0.05 - 0.10 parts of phospholipids, 0.02 - 0.08 parts of carrageenan, 0.1 - 0.2 parts of arabic gum, and 90 - 120 parts of water.

[0007] By limiting the dosages of each component within a reasonable range value, the whole-nutrition formula food of the present invention enables better synergistic effects among the components, so that the obtained whole-nutrition formula food has a high energy density and can meet the special nutritional needs of highly catabolic patients such as severely burned patients.

[0008] Among them, protein in the whole-nutrition formula food not only provides essential nutrients for the human body, but also supports the normal operation and health status of the body through various physiological functions. The energy contribution ratio of protein in the whole-nutrition formula food of the present invention is 20 - 25%, which is greater than the recommended protein energy contribution of 10% - 20% in "Dietary Reference Intakes for Chinese Residents", and at the same time meets the requirements of high-protein whole-nutrition formula food.

[0009] Fat is a high-energy nutrient that can provide energy to the human body and help with the absorption and utilization of fat-soluble vitamins (such as vitamins A, D, E, and K).

[0010] Carbohydrates can be quickly absorbed and utilized by the human body to maintain normal physiological functions and also maintain the normal functions of the brain. When the intake of carbohydrates is insufficient, fat metabolism will produce ketone bodies, and an appropriate amount of carbohydrates can prevent excessive ketone bodies.

[0011] Compound vitamins can participate in the metabolic process, maintain the physiological functions of the human body, and support growth and development.

[0012] Compound minerals can maintain the physiological functions of the human body, regulate acid-base balance and water balance, and participate in the metabolic reactions of the human body.

[0013] Fructooligosaccharide can promote intestinal health, regulate blood sugar, promote mineral absorption, and regulate lipid metabolism.

[0014] β-hydroxy β-methyl butyrate (HMB) is a natural product in the leucine metabolic process. Supplementing HMB through the new food raw material CaHMB is an important way to promote muscle protein synthesis and slow down muscle protein breakdown. Supplementing CaHMB is beneficial to correcting negative nitrogen balance and beneficial to the muscle health of patients with negative nitrogen balance.

[0015] As an emulsifier, mono- and diglycerol fatty acid esters can better mix oil and water, prevent layering, improve the stability of food, and also enhance the taste.

[0016] Phospholipids have the dual properties of hydrophilicity and lipophilicity and can be used as emulsifiers to promote the absorption and metabolism of fat. It helps to reduce blood viscosity, prevent cardiovascular diseases, and at the same time has a protective effect on the nervous system.

[0017] Carrageenan can increase the viscosity and stability of food, prevent food layering, and also improve the taste. Carrageenan can also combine with proteins to prevent protein denaturation and maintain the freshness of food.

[0018] Arabic gum has emulsifying and stabilizing effects, can prevent oil-water separation, improve the stability of food, help to improve the solubility of other components in food, and make the taste of food more uniform.

[0019] Preferably, the whole-nutrition formula food comprises the following components in parts by weight: 10 - 13 parts of protein, 5 - 7 parts of fat, 25 - 28 parts of carbohydrates, 0.4 - 0.45 parts of compound vitamins, 1.3 - 1.4 parts of compound minerals, 1 - 1.5 parts of fructooligosaccharide, 0.18 - 0.2 parts of calcium β-hydroxy-β-methylbutyrate, 0.05 - 0.06 parts of mono- and diglycerol fatty acid esters, 0.08 - 0.10 parts of phospholipids, 0.06 - 0.08 parts of carrageenan, 0.18 - 0.2 parts of Arabic gum, and 90 - 120 parts of water.

[0021] Preferably, the compound vitamins comprise the following nutrients in parts by weight: 0.45 - 1 part of vitamin A, 0.010 - 0.014 part of vitamin D, 14 - 20 parts of vitamin E, 0.040 - 0.060 part of vitamin K, 1 1.9 - 4 parts of vitamin B 1 1.9 - 4 parts of vitamin B 2 1.9 - 4 parts of vitamin B6 1.9 - 4 parts, vitamin B 12 2.6 - 4.1 parts, niacin 4.2 - 6 parts, folic acid 0.2 - 0.25 parts, pantothenic acid 5 - 6 parts, vitamin C 75 - 400 parts, and biotin 0.028 - 0.060 parts. This ratio can significantly improve the nutritional balance, safety, stability, and taste of the total nutritional formula food, while optimizing cost - effectiveness and better meeting the nutritional needs of severely burned patients.

[0022] Furthermore, the compound mineral includes the following nutrients in parts by weight: Sodium 125 - 165 parts, potassium 160 - 220 parts, copper 0.090 - 0.5 parts, magnesium 25 - 40 parts, iron 1.5 - 3.5 parts, zinc 0.8 - 3.5 parts, manganese 0.045 - 0.65 parts, calcium 70 - 200 parts, phosphorus 50 - 100 parts, iodine 0.012 - 0.035 parts, chlorine 20 - 300 parts, selenium 0.006 - 0.030 parts, choline 45 - 225 parts, chromium 0.0035 - 0.065 parts, and molybdenum 0.007 - 0.095 parts. This ratio can strengthen the synergistic effect among various nutrients, playing the roles of nutritional balance, reducing complications, and assisting drug treatment.

[0023] Preferably, the compound mineral includes the following nutrients in parts by weight: Sodium 150 - 160 parts, potassium 180 - 190 parts, copper 0.35 - 0.5 parts, magnesium 30 - 40 parts, iron 2.5 - 3.2 parts, zinc 2.0 - 3.1 parts, manganese 0.35 - 0.65 parts, calcium 110 - 190 parts, phosphorus 60 - 95 parts, iodine 0.02 - 0.032 parts, chlorine 225 - 285 parts, selenium 0.01 - 0.030 parts, choline 110 - 225 parts, chromium 0.007 - 0.065 parts, and molybdenum 0.009 - 0.095 parts.

[0024] Furthermore, the energy density of the total nutritional formula food is 1.5 - 2.0 kcal / mL.

[0025] According to the second aspect of the present invention, the present invention also provides a preparation method of the above - mentioned total nutritional formula food, which is characterized by including the following steps: Step (1): Dissolve the protein - containing raw material and fructooligosaccharide in water to obtain liquid A; mix the arabic gum, carrageenan, and carbohydrate - containing raw material evenly and then disperse them in water to obtain liquid B; Step (2): Add liquid B to liquid A and then perform high - speed shearing to obtain liquid C; Step (3): Dissolve the raw materials of the compound minerals and calcium β-hydroxy-β-methylbutyrate in water to obtain liquid D; add the liquid D to the liquid C and stir to obtain the aqueous phase liquid E; add mono- and diglycerol fatty acid esters and phospholipids to the raw materials containing fat and perform high-speed shearing to obtain the oil phase liquid F; Step (4): Add the oil phase liquid F to the aqueous phase liquid E and perform high-speed shearing to obtain an emulsion; after cooling the emulsion, adjust the pH to 6.8 - 7.2 with a phosphoric acid solution; Step (5): Dissolve the raw materials of the compound vitamins in water and then add them to the emulsion, make up the water, and stir evenly; Step (6): Subject the material after adding water to homogenization, ultra-high pressure sterilization, and canning.

[0026] The preparation method of the full-nutrition formula food of the present invention adds and mixes the raw materials step by step, which can avoid the interaction between certain components and reduce the loss or denaturation of nutrients. Through high-speed shearing and the use of emulsifiers (such as mono- and diglycerol fatty acid esters, phospholipids), the oil phase and the aqueous phase are fully emulsified to form a stable emulsion, which helps the uniform distribution of fat and fat-soluble vitamins and improves the stability of the product. Through high-speed shearing and emulsification, it is ensured that all components are evenly dispersed in the product, avoiding layering or precipitation, and making the product more uniform in taste. Adjusting the pH value of the emulsion to 6.8 - 7.2, which is close to the physiological pH value of the human body, helps the absorption and utilization of nutrients and reduces the stimulation to the gastrointestinal tract. The preparation method of the full-nutrition formula food of the present invention uses ultra-high pressure sterilization technology, which can achieve the sterilization of the product at a lower temperature, avoid the destruction of nutrients by high-temperature sterilization, and effectively kill microorganisms to ensure the safety of the product.

[0027] Further, in the step (6), the pressure of the ultra-high pressure sterilization is 400 - 800 Mpa, the time is 10 - 40 min, and the temperature is 15°C - 35°C. The full-nutrition formula food obtained under this condition can achieve more efficient sterilization while better maintaining the nutrients in the food from being destroyed.

[0028] Further, the raw material containing protein is selected from whey protein and hydrolyzed whey protein.

[0029] Further, the raw material containing fat includes one or more of medium-chain triglycerides, low-erucic acid rapeseed oil, and sunflower oil.

[0030] Further, the raw material containing carbohydrates is selected from maltodextrin.

[0031] Further, the raw materials of the compound vitamins are selected from vitamin A acetate, cholecalciferol, dl-α-tocopherol acetate, and vitamin K 1, thiamine hydrochloride, riboflavin, pyridoxine hydrochloride, cyanocobalamin, nicotinamide, folic acid, D-calcium pantothenate, sodium L-ascorbate and D-biotin.

[0032] Further, the raw materials of the compound minerals are selected from sodium citrate dihydrate, potassium citrate monohydrate, potassium dihydrogen phosphate, copper sulfate, magnesium carbonate, ferrous sulfate, zinc sulfate monohydrate, manganese sulfate monohydrate, tricalcium phosphate, potassium dihydrogen phosphate, potassium iodide, potassium chloride, sodium selenite, chromium chloride and sodium molybdate.

[0033] Further, the speed of high-speed shearing in the step (2) is 2000 - 10000 rpm, and the time is 10 - 30 min. Further, the speed of high-speed shearing in the step (3) is 2000 - 10000 rpm, and the time is 10 - 20 min.

[0034] Further, the speed of high-speed shearing in the step (4) is 2000 - 10000 rpm, and the time is 20 - 60 min.

[0035] Further, the speed of stirring in the step (3) is 300 - 1000 rpm, and the time is 10 - 15 min.

[0036] Reasonably controlling the speed and time of the above high-speed shearing and stirring can significantly improve the stability, quality and production efficiency of the total nutrient formula food, while reducing energy consumption and material waste, and ensuring the consistency of product quality.

[0037] Further, in the step (6), the number of homogenization times is 2 - 3 times, the homogenization pressure is 200 - 600 bar, and nitrogen protection is used during the preparation process; nitrogen protection is used during the canning process. Limiting the conditions of homogenization and canning within reasonable conditions can further improve the stability, quality and safety of the total nutrient formula food.

[0038] The beneficial effects produced by the technical solution provided by the present invention are as follows: A total nutrient formula food of the present invention limits the amounts of protein, fat, carbohydrate, compound vitamins, compound minerals, fructooligosaccharide, β-hydroxy-β-methylbutyric acid calcium, mono- and diglycerol fatty acid esters, phospholipids, carrageenan, arabic gum and water within reasonable range values, so that better synergistic effects are formed among the components, and the obtained total nutrient formula food has a high energy density (1.5 - 2.0 kcal / mL), which can meet the special nutritional needs of highly catabolic patients such as severely burned patients.
