Description

A kind of dendrobium polysaccharide premixed powder and its preparation and application
Technical field
The invention belongs to field of food science, specifically a kind of conducive to the dendrobium polysaccharide premixed powder swallowed and its preparation Methods and applications.
Background technique
Dysphagia, which refers to exist during the transport by the substances such as solid-state or aqueous liquid foodstuff, drug from oral cavity to stomach, is stranded It is difficult.Dysphagia can betide each age group crowd, have within 50 years old or more 22%, over-65s to have 10%~30%, 70 years old or more There is 40% people to suffer from function of deglutition disorder, as the trend risen, the elderly's epiglottis reflection function drop is presented in the increase at age Low, constrictor pharyngis activity weakens, and is more also easy to produce aphetite disorder.The especially patients such as neurodegenerative disease, there is 60%~80% The puzzlement of neurodegenerative disease patient and stroke patient more than 30% by dysphagia.Dysphagia crowd largely exists The problems such as dehydration, malnutrition, electrolyte disturbance, and easily lead to patient and food is sucked into tracheae, serious person when swallowing food Aspiration pneumonia can occur and lead to death.
Patients with deglutition disorders quality of life is adversely effected.Alleviate dysphagia method mainly swallow function training, Nasal feeding substitutes feed, operative treatment, electronic stimulation and food drug physical property improving etc..From swallowing in terms of angle, liquid food increases It is thick that viscosity can be improved, slow down its speed for flowing through throat, be conducive to swallow, reduces the danger of food sucking lung.Therefore, exist In the diet nursing of dysphagia patients, improving the physical property such as viscosity, the rheological characteristic of dilute slop is critically important means.
Food requirement suitable for dysphagia patients is the viscosity that density is uniform, appropriate, is not easy loosely, by pharynx and food It is easily deformed when road, is not easy the properties such as the bioactivity and the color that remain on mucous membrane, and take into account food.Dysphagia The common slop thickener of therapy field is divided into two classes: starch and polysaccharide.Starch is since starch granules is in liquid In swelling and partly soluble property, be easy to cause the mouthfeel of paste, influence the acceptance level of patient, and its thickening liquid Viscosity it is very big with the variation of temperature at any time, hardly result in the thickened fluid of stable homogeneous.Polysaccharide is not easy by human oral cavity In ptyalin decompose, tangled structure can be formed in aqueous solution and keep stable glutinous within the relatively long time Degree, therefore it is used widely in dysphagia nursing field.
Xanthan gum due to it there are strong pseudoplastic rheological properties to show product in the diet nursing of dysphagia The effect of pole.The fluid of dysphagia therapeutic purposes should also have stable viscosity, to meet the needs of patient safety is swallowed.It is yellow Virgin rubber is as thickener, though it is widely used in dysphagia diet nursing, however, thixotroping possessed by the fluid of its thickening Property, so that its viscosity is easy the factors such as at any time upon configuration and apparent variation occurs, to be difficult to ensure that it edible reaches setting Value in turn results in eater and swallows that there are security risks.In addition, guar gum, locust bean gum, hyaluronic acid etc. are used also as gulping down Difficult diet thickener is swallowed, however these hydrophilic colloid thickeners are difficult to provide other beneficial functions, and content is higher has Certain disagreeable taste.
Main active constituent is polysaccharide compound in dendrobium nobile, has and improves immunity, hypoglycemic, antitumor, antioxygen The effects of change, liver-protecting and stomach-protecting and anti-cataract.Since eighties of last century the fifties, researcher is in succession to the extraction of dendrobium polysaccharide Purifying, structure elucidation and functional activity etc. have done numerous studies, and achieve certain achievement.We have found in scientific research Dendrobium polysaccharide can be used as the food nature modifying agent for improving dysphagia crowd.
With the growth of aging populations quantity, dysphagia is just becoming an increasingly serious social concern, serious shadow Human health and quality of life are rung, therefore studies the food or drug physical property improving for being suitable for the special medicine purposes of dysphagia Agent will have great importance and great market potential.
