Description

Technical Field

[0001] This invention relates to the field of biomedicine, specifically to a composition for improving the safety of eating in patients with dysphagia, its preparation method, and its application. Background Technology

[0002] Dysphagia, caused by various factors and occurring in different locations, severely affects patients' food intake, nutrient absorption, and oral medication administration. It can even lead to aspiration pneumonia or infection, and in severe cases, endanger life. The 2017 "Epidemiological Survey Report on Dysphagia in Specific Populations in China" showed that the prevalence of dysphagia in China was 38.7%.

[0003] The causes of dysphagia include physiological reasons, surgical procedures, genetic factors, and disease-related causes. These include age-related decline in swallowing ability, muscle weakness caused by radiotherapy and chemotherapy, neurodegeneration related to physiological processes and the nerve innervation of the swallowing reflex, and diseases associated with neurological disorders, infectious diseases, autoimmune diseases, metabolic diseases, myopathic diseases, iatrogenic diseases, post-surgical muscle or neurological disorders, radiation therapy, corrosive and structural diseases, etc.

[0004] For patients with dysphagia who can eat orally, adjusting the texture and consistency of food is a prerequisite for ensuring safe and effective eating. The texture of food affects the swallowing process; by adjusting the texture, some patients can eat safely and effectively. Studies have shown that adding thickening agents to liquid foods increases their viscosity and reduces their flowability, giving patients sufficient time to react and control the epiglottis from covering the trachea. This is an important method for prolonging the swallowing time of liquid foods, reducing swallowing safety risks, and is also one of the effective measures to address eating difficulties in patients with dysphagia.

[0005] CN105831711B discloses an instant thickener that provides a comfortable viscosity and its preparation method, wherein the thickener is composed of 20.00% xanthan gum and 80.00% maltodextrin.

[0006] CN 110326792 A discloses a non-complete nutritional liquid diet based on tamarind polysaccharide, containing 0.2% to 0.35% tamarind polysaccharide, 0.15% to 0.3% xanthan gum, 2% to 12% erythritol, 2% to 10% resistant dextrin and 1% to 15% nutrients, with the balance being water.

[0007] CN110522011A discloses a thickening component for improving swallowing disorders, containing 30%–45% hydrophilic gum, 10%–30% starch, and 40%–60% maltodextrin, wherein the hydrophilic gum includes xanthan gum, guar gum, locust bean gum, and locust bean gum.

[0062] The composition of Example 1 was prepared into solutions of 1.25%, 2.50%, 3.75%, and 5.00% by adding water, and the viscosity was tested at room temperature. The results showed that the product viscosity increased rapidly with increasing sample concentration, exhibiting non-Newtonian fluid characteristics.
