Abstract

The invention discloses an instant gellan gum and its preparation method. The instant gellan gum is prepared through treating gellan gum powder as an initial raw material and adopting a boiling, granulating and drying device. The method comprises the following steps: 1, gellan gum powder feeding: introducing the raw material gellan gum powder to the fluidized bed bottom of the boiling, granulating and drying device through purified cold air in order to make the raw material in a boiling state; 3, aqueous KCl solution wetting: injecting an aqueous KCl solution to humidify and granulate the gellan gum powder; 3, gellan gum solution injecting: atomizing a gellan gum solution having a small concentration, and uniformly injecting the raw material gellan gum powder for dressing boiling from the upper portion of the fluidized bed; 4, dressing; and 5, drying the obtained particulate product to obtain an instant colloidal matrix. The instant gellan gum prepared through adopting the method disclosed in the invention is used for solving the problems comprising difficult dissolving, easy formation of fish eye-like blocks in the dissolving process, slow dissolving time and fly dusts of powdery gellan gums produced at present.

Description

technical field [0001] The invention relates to a gellan gum, in particular to an instant gellan gum; in addition, the invention also relates to a preparation method of the instant gellan gum. It belongs to the preparation of compounds containing sugar residues. Background technique [0002] Gellan Gum (Gellan Gum) is a Gram-negative bacterium isolated from water lilies—Pseudomonas elodea (Pseudomonas elodea) that is purified by fermentation of carbohydrates and extracted and refined. Polysaccharide colloid, almost white powder, is a new type of fully transparent gel. The gellan gum products in the prior art are mostly powdery. [0003] Gellan gum is a high molecular polysaccharide, and its dissolution process has something in common with other high polymers. The dissolution process of the polymer goes through two stages. First, the solvent molecules penetrate into the polymer to expand the volume of the polymer, that is, the swelling process, and then the polymer is even...
