Nutritional composition for improving motor system function of old people and preparation method thereof
Technical Field
The invention relates to a nutritional composition for improving the motor system function of the elderly, and a preparation method and application thereof.
Background
The global aging speed is increasing. The predictions promulgated by the united nations show that the world's proportion of the elderly population over 60 years of age is about 10.0% in 2000, will rise to 15.1% in 2025, and will be as high as 21.7% in 2050. With the aging, the physiological functions of the locomotor system of the human body are gradually degraded, most of the elderly have the problems of osteoporosis, degenerative osteoarthropathy (articular cartilage degradation) and skeletal muscle reduction, the consequences of which often cause the activity of the elderly to be reduced, and daily actions such as walking, sitting, ascending, lifting heavy objects and the like to be affected, even cause balance disorder, difficulty in standing, great easiness in falling and the like.
The locomotor system consists of three organs, bone joints (joints) and skeletal muscle. Bones are joined together in different joints (inactive, semi-active, or active) to make up the skeleton. Forms the basic shape of the human body and provides attachment for muscles which contract under the nerve innervation, pulling the attached bone, pivoting on the movable bone connection, creating a lever motion. From the kinematic perspective, the bone is the passive part, the skeletal muscle is the dynamic part, and the joint is the kinematic hinge. In fact, the three muscles, bones and bone joints are closely related in the movement function and have mutual regulation.
According to the consensus of the experts of muscle, bone and osteoporosis, osteoporosis is closely related to muscle and bone. Osteoporosis and sarcopenia present many common risk factors. The motor systems of muscles and bones are all originated from mesoderm and have common mesenchymal precursors, and the two are closely related in motor functions. Muscle is a ligament that connects bones and is closely related to the growth and development of bones. Recent researches find that muscles and bones are important endocrine organs, relevant factors secreted by the muscles are involved in regulation and control of the bones and have certain influence on growth, development and development of the bones, and the bone factors can also regulate muscle mass and muscle strength. Developmental biology studies suggest that there may be molecular signaling networks that coordinate muscle and bone mass, and regulatory factors that can couple muscle and skeletal growth in the circulation and local microenvironment. Muscles and bones are also regulated by each other, in addition to being influenced by both internal (neuroendocrine) and external (force) factors.
The development, function and aging of the skeletal muscle system are an organic whole. The strength of muscle contraction under the control of the nervous system is an important factor determining the bone mass and strength. The effect of muscle strength on bone density is more pronounced than the effect of muscle content on bone density. The number of skeletal muscles is an important factor in determining bone density. The number of muscles and the bone density are increased and decreased synchronously. Loss of skeletal muscle can lead to decreased bone density. Muscular atrophy, muscle strength decline and muscle function decline can lead to accelerated and thinned cortical bone absorption and weakened ability to resist shear force, torsion and bending force; the number of horizontal trabeculae in the cancellous bone is reduced, the vertical trabeculae become sparse, and the bone density becomes lower and lower. The bone adapts to the changes in the strength of muscle contraction by changing the bone mass and strength. The mechanical stimuli to which bones are subjected have a significant effect on bone density. Bone cells convert mechanical stimuli into biochemical signals that regulate bone density. The decrease in bone density is a result of an imbalance in the regulation of the musculoskeletal system.
Degenerative osteoarthropathy, also known as osteoarthritis, is a degenerative disease, which is degenerative injury of articular cartilage, reactive hyperplasia of articular margin and subchondral bone caused by aging, obesity, strain, trauma, congenital abnormality of joints, joint deformity, etc. Studies have shown that cartilage is nutritionally impaired, cartilage matrix is degraded over synthesis, and reduced repair capacity is a major cause of degenerative joint disease. The research result of the knee arthritis shows that the weakness of the skeletal muscle of the knee joint (skeletal muscle atrophy and muscle strength decline) is an important pathological link of the knee arthritis, and is generally considered to be caused by muscle inhibition and secondary atrophy caused by arthritis pain. And it has been considered that age-related quadriceps femoris weakness plays an important role in the pathogenesis of knee osteoarthritis.
However, in the fields of nutrition and food, the intervention on the motion system is mostly part of individual intervention, and no systemic overall consideration exists. Such as calcium and/or vitamin D to improve osteoporosis, glucosamine to relieve joint cartilage degradation. And loss of skeletal muscle is largely ignored by the general public.
Generally, most old people have the problems of osteoporosis, degenerative osteoarthropathy (articular cartilage degeneration) and skeletal muscle reduction, and the vitamin D calcium tablets for improving osteoporosis and the glucosamine for relieving joint degeneration cannot integrally improve the motion system, so that the effect is single and the product is not an ideal product.

The invention also comprises the application of the nutritional composition or the preparation thereof for improving the motor system function of the elderly in preparing food, health-care products or medicines.
Compared with the prior art, the invention has the following beneficial effects:
in terms of improving muscle attenuation:
(1) through the combination of whole protein (whey protein) and hydrolyzed protein (whey protein peptide and collagen peptide), gradient absorption of protein is formed, and energy and raw materials are continuously provided for muscles;
(2) the whey protein contains high leucine, and meanwhile, part of leucine and a metabolite beta-hydroxy-beta-methylbutyric acid thereof are supplemented, the leucine promotes the strongest synthesis of skeletal muscle protein, the beta-hydroxy-beta-methylbutyric acid is beneficial to promoting the increase of muscle volume to the maximum extent, and the muscle mass and function reduction of the old can be reversed by cooperating with other nutrient substances;
(3) the vitamin B group participates in energy metabolism, and can further regulate muscle energy supply. The supply of energy is an important source of muscle strength. The vitamins participating in energy metabolism with coenzyme or prosthetic group are mainly B vitamins, and mainly comprise VB1, VB2 and VB 6. The active form of VB1 constitutes the coenzyme of the α -keto acid dehydrogenase system and transketolase in vivo and is mainly involved in the metabolism of sugars and branched-chain amino acids. VB2 is bound to specific proteins in vivo in the form of flavin mononucleotide and flavin adenine dinucleotide coenzyme, and is widely involved in redox reactions in metabolism. Since flavin adenine dinucleotide is a component of the respiratory chain, VB2 is a central link for energy production. VB6 in its active form pyridoxal 5' -phosphate is involved in amino acid metabolism as a coenzyme for many enzymes (e.g., transaminases, decarboxylases).
(4) Vitamin D is added to increase muscle strength and function. Vitamin D functions via the following two pathways: in one aspect, vitamin D promotes muscle fiber synthesis by binding to specific vitamin D receptors on the surface of skeletal muscle cells, resulting in increased mRNA expression. On the other hand, vitamin D can increase calcium storage of sarcoplasmic reticulum and promote muscle contraction function.
(5) The wheat protein peptide contains rich glutamine, the glutamine is the amino acid which is most consumed by metabolism under the stress state of a human body and is also the amino acid with the most content in the skeletal muscle of the human body, the volume of muscle cells can be increased, the decomposition of protein is inhibited, and meanwhile, the glutamine can regulate the intestinal barrier function and the immunity of the old and promote the absorption of nutrient components;
(6) the oxidative stress of muscle is reduced by supplementing vitamin C and vitamin E with antioxidant effect. Reduce the damage to the muscle caused by oxidative stress and maintain the muscle function.
In the aspect of improving osteoporosis:
(1) supplement the main components of bone, calcium and collagen (peptides). 97-98% of bone tissue is bone matrix, 65% of vitamin mineral substance in the bone matrix, 35% of organic substance in the bone matrix, and 95% of the organic substance is collagen. Calcium and collagen supplementation can help to increase the strength and toughness of bones, thereby improving osteoporosis;
(2) supplementing vitamin K2. Vitamin K2 plays an important role in various links of bone metabolism, has two-way effects of promoting bone formation and inhibiting bone resorption, and can improve the unbalanced state of bone tissue metabolism and bone quality, thereby increasing bone strength.
(3) Supplementing casein phosphopeptide and vitamin D. The casein phosphopeptide can promote the absorption of calcium by small intestine. Vitamin D can promote absorption of calcium and phosphorus by intestinal tract, and can stimulate osteoblast to promote maturation of bone-like tissue and bone salt deposition.
(4) Supplementing vitamin C, and promoting bone collagen regeneration. In the synthesis of collagen, proline and lysine residues in the polypeptide chain must be hydroxylated into hydroxyproline and hydroxylysine residues under the catalysis of proline carboxylase and lysine hydroxylase. Vitamin C is one of the accessory factors necessary for the maintenance of the activity of these hydroxylases.
(5) And supplementing magnesium. Magnesium is an element essential for bone cell structure and function, which allows bone growth and maintenance, and it can affect bone resorption.
In the aspect of improving the articular cartilage damage:
(1) the chicken breast cartilage powder contains rich collagen, glucosamine, chondroitin sulfate and other important bone joint components, contains various active factors such as basic fibroblast growth factor, insulin-like growth factor and the like, and can promote the growth of chondrocytes, accelerate the synthesis of bone matrix so as to promote the repair of articular cartilage and slow down the degradation of articular cartilage;
(2) dimethyl sulfone is one of the major supplies of sulfur in the human body for the synthesis of methionine, cystine and sulfur-containing peptides, proteins, and sulfur-containing tissues. The mucous membrane at the joint consists of sulfur-containing protein, glucosamine and the like. The sulfur-containing protein and glucosamine have the functions of promoting the production of collagen, increasing the combination of water and helping to repair damaged cartilage. Can restore the injured cartilage to be normal, and the periosteal fluid is more concentrated and viscous, thereby strengthening the protective function of periosteum, relieving the friction of bone joints and reducing the pain.
(3) The chitosan oligosaccharide is an oligosaccharide formed by connecting 2-10 glucoseamine through beta-1, 4 glycosidic bonds, can promote the repair of synovium and cartilage, reduce inflammatory transmitters in joint synovial fluid, and effectively improve the symptoms of osteoarthritis.
(4) Curcumin and turmeric are also traditional blood-activating and stasis-removing medicines, and can activate blood, promote qi circulation and relieve pain. The effect of protecting articular cartilage against osteoarthritis is mainly achieved by: curcumin can remove free radicals by inhibiting oxidase, and has antioxidant effect, thereby preventing osteoarthritis; curcumin inhibits the consumption of matrix metalloproteinase to cartilage matrix and increases the generation of type II collagen; curcumin accomplishes anti-inflammatory response by inhibiting cytosolic phospholipase a2, cyclooxygenase 2, lipoxygenase 5.
The invention is based on the thought of the system nutrition theory, and is integrally considered from three aspects of bones, joints and muscles, thereby pertinently supplementing the functional state of the motion system of the old people with the required nutrient components. The whole health of the motion system of the old is promoted and realized cooperatively through the functional effects of all nutrients and the progressive and scientific proportion of the nutrients, so that the daily activity and the life quality of the old are improved.
The composition provided by the invention can improve the functions of a human motion system from multiple aspects of promoting muscle growth, reducing muscle catabolism, improving osteoporosis, promoting articular cartilage repair and the like so as to improve the activity of old people. Meanwhile, the accumulation of free radicals in the body can be effectively eliminated, the effect of oxidative stress reaction in the body is reduced, and the body is healthier.

Experimental example 1 experiment for improving muscle attenuation effect of exercise system
1. Experimental sample
The nutritional composition for improving the motor system function of the elderly prepared in example 1, the nutritional compositions prepared in comparative example 1 and comparative example 4, and the compound protein composition of comparative example 5, whey protein (the same as whey protein in example 1).
2. Experimental methods
84C 57BL/6 mice, 6-7 months old, were randomly divided into 7 groups of 12 mice each. Wherein 1 group is designated as a normal group, and 6 groups of mice are subcutaneously administered with dexamethasone at a concentration of 0.1ml/10g for 42 days to establish a muscle decay model. Corresponding treatments were given for 60 days thereafter. Before molding and before and after treatment, body composition (from Congjia biological products (China) Co., Ltd.) was measured for each group of mice by an Echo MRITM small body composition analyzer, and the muscle content was measured. The treatment of each group of mice was as follows:
normal group: 12, normal feed and water feeding only;
model group: 12, normal feed and water feeding only;
example 1 group: 12 individuals, gavage daily for 60 days except for normal feed and water feed, the nutritional composition of example 1 at 7.8 mg/g;
comparative example 1 group: 12, gavage 5.3mg/g of the nutritional composition of comparative example 1 every day for 60 consecutive days except for feeding with normal feed and water;
comparative example 4 group: 12, gavage daily except for normal feed and water feeding, and gavage daily for 60 days with 5.3mg/g of the comparative example 4 nutritional composition;
comparative example 5 group: 12, except for feeding with normal feed and water, the stomach is drenched every day, and the compound protein composition of comparative example 5 is 4.5 mg/g for 60 days continuously;
whey protein group: 12 animals except for normal feed and water, were gavaged daily for 60 days with 2.5mg/g whey protein.
Note: the molding principle is as follows: glucocorticoids promote protein breakdown in a variety of tissues, such as muscle, skin, lymphatic, and bone tissues. At the same time, it can inhibit protein synthesis and reduce assimilation, so that negative nitrogen balance appears, muscles and lymph tissue are atrophied, and wound healing is slow. Clinical studies have demonstrated that patients treated with glucocorticoids have a significant reduction in muscle content. Dexamethasone is a hormone medicine with the highest potency and the longest action duration in glucocorticoid, so that the establishment of a muscle decay syndrome model by utilizing dexamethasone has the advantages of short period, obvious effect and the like. Dexamethasone induces muscle decline in mice primarily by promoting protein degradation.

Experimental example 3 experiment for improving gonarthritis effect of locomotor system
1. Experimental sample
Nutritional composition for improving motor system function of elderly prepared in example 3, nutritional composition prepared in comparative example 3, glucosamine + chondroitin sulfate composition (consisting of glucosamine 0.5g, chondroitin sulfate 0.2 g).
2. Experimental methods
60 SD rats, randomly divided into 5 groups of 12 rats each. In the other 4 groups, iodoacetic acid (1mg, 50. mu.l) was injected into the knee joint cavity of the right knee joint of rats 1 time per week for 4 consecutive times to perform knee arthritis modeling. Rats in each group were given a corresponding treatment one week before the start of molding. 30 days after the model building is finished, the rats are sacrificed to extract the cartilage tissue specimens of the right knee joint, and the expression of type II collagen and cartilage proteoglycan (aggrecan) in the cartilage of the right knee joint of each group of rats is detected by a reverse transcription-polymerase chain reaction (RT-PCR) method. The treatment of each group of rats was as follows:
normal group: 12 animals fed with normal feed and water only
Model group: 12 animals fed with normal feed and water only
Example 3 group: 12 animals except for soybean and its product feed and water, gavage the stomach every day with 8mg/g of the nutritional composition of example 3 for 65 consecutive days
Comparative example 3 group: 12 animals except for feeding soybean and its product feed and water, and gavage the stomach every day to obtain the nutritional composition of comparative example 3 (4.7 mg/g) for 65 days
Glucosamine + chondroitin sulfate group: 12 animals except semen glycines and its product feed and water, respectively, feeding with 250 μ g/g composition (composed of glucosamine 0.5g and chondroitin sulfate 0.2 g) of glucosamine and chondroitin sulfate for 65 days
Note: the principle of osteoarthritis molding is as follows: the iodoacetic acid is selected for injecting in the knee joint cavity, so that the original steady state of the joint cavity is changed, MIA has certain destructive effect on articular cartilage and peripheral synovial membrane toughness, and the metabolism of cartilage and subchondral bone is changed, the stability of the internal environment of the joint is destroyed, cartilage cells are apoptotic, and cartilage is abraded. Meanwhile, other structures in the joint are damaged, and fibrous tissues around the joint are proliferated to form osteophytes, which finally develop into osteoarthritis.
Collagen type ii and cartilage proteoglycan are important components of articular cartilage and also important marker components of articular cartilage degeneration.
3. Results of the experiment
The results of the specific experiments are shown in Table 3 below.

As can be seen from Table 3, the expression of collagen type II and cartilage proteoglycan in the normal group was significantly higher than that in the model group (P < 0.01); the model is successfully established;
the increase in type II collagen and cartilage proteoglycan was very significantly different in the example 3 group compared to the model group (P < 0.01);
the group of example 3 also showed a very significant improvement (P < 0.05) in the case of type II collagen and cartilage proteoglycan compared to the group of comparative example 3, glucosamine + chondroitin sulfate;
the expression of type II collagen and cartilage proteoglycan of the glucosamine and chondroitin sulfate group rats is better than that of the comparative example 3, but the difference is not significant (P is more than 0.05).
The experimental results show that the treatment effect of the group in example 3 is significantly better than that of a few of the components which are used independently in the aspect of improving the functions of the bone joints of the motion system of the old.
EXAMPLE 4 product stability (high temperature, high humidity acceleration)
1. Test sample
The nutritional composition for improving the motor system function of the elderly in example 1 is subpackaged into 45g of packaging bags according to a conventional method.
2. Experimental methods
The shelf life of the product is estimated to be at least 12 months by referring to the like products. The shelf life at different temperatures is initially assumed to be as shown in table 4 below, with a 1-fold increase in reaction for each 10 ℃ increase in temperature.

The test samples are placed at the temperature of 60 ℃ and the humidity of 75% to carry out high-temperature high-humidity accelerated test, and the detection of relevant indexes is carried out on the 0 th day and the 23 rd day. The method mainly aims to preliminarily predict the shelf life of the product and the stability, physical stability, water activity and sensory state of each nutrient component in the shelf life range.
The detection of the nutrient components comprises main nutrient components of protein, fat and carbohydrate, and easily lost nutrient components of vitamin B group, vitamin C and vitamin E.
And (3) detecting physical stability: the product is brewed according to a certain proportion and then is detected by a LUMiSizer 611 type rapid stability analyzer to detect the Slope value (the Slope value represents the change speed of the light transmittance of the liquid in a period of time, the curve Slope value can be obtained by drawing the whole light transmittance versus time, the larger the value is, the faster the light transmittance of the liquid is changed, the worse the liquid stability is, otherwise, the smaller the Slope value is, the more stable the liquid is).
And (3) water activity detection: the ease of growth and reproduction of the microorganism can be evaluated. Each microorganism has its minimum water activity requirement for growth and reproduction in food. If the water activity of the food product is below this requirement, the growth and propagation of microorganisms is inhibited. At water activities below 0.6, most microorganisms are unable to grow.
The sensory state evaluation includes: color, smell, tissue state, color, smell, solubility, etc.
