Abstract

The invention discloses a xanthan gum compound thickener with good instant solubility and high viscosity and a preparation method of the xanthan gum compound thickener. The instant xanthan gum compound thickener obtained by the preparation method disclosed by the invention achieves an instant effect in cold water, can provide high viscosity at low concentration, and can keep a stable thickening effect for a long time. Meanwhile, the technological process is easy to operate, economical, safe, free of pollution and suitable for large-scale industrial production. The product provides a compound thickening agent with good instant solubility and high viscosity for thickening instant powdery food and a meal aid for patients with dysphagia.

Description

technical field [0001] The invention belongs to the field of food additives, and relates to a xanthan gum compound thickener with good instant solubility and high viscosity and a preparation method thereof. Background technique [0002] Dysphagia refers to the symptoms of obstacles in the transportation of food and liquid from the mouth to the stomach. It is common in the elderly and patients with esophageal lesions who have impaired chewing and swallowing functions. When patients with dysphagia eat, food boluses are easily aspirated and enter the trachea, causing choking, and even shock and death in severe cases, seriously affecting the quality of life of the patient. Aspiration can be prevented to a certain extent by changing eating behaviors. One of the important means is to use thickeners to thicken food to form "food boluses" to control its flow rate when swallowing, so as to achieve the purpose of meal aid. [0003] At present, most meal aids for patients with dysphag...
