Problems solved by technology

However, all of these articles did not study gum arabic and did not evaluate the application value of related graded products
[0008] Moreover, the existing gum arabic modification technologies are thermal modification and radiation modification. Although these two methods can produce better gum arabic modified products, they are based on sacrificing some characteristics of gum arabic. , such as a decrease in solubility
Moreover, in the above-mentioned modification process, along with the aggregation between gum arabic molecules, smaller fractions are polymerized into fractions with larger molecular weights, which may destroy the natural structure and properties of gum arabic

Embodiment 1

[0046] Embodiment 1 thermally modified gum arabic and hyaluronic acid

[0047] The method of the invention is applicable to various modified gum arabic, including thermally modified gum arabic.

[0048] Gum Arabic is a complex polysaccharide containing a small amount of protein components. The polysaccharide part is composed of arabinose, galactose, rhamnose and their uronic acids. The molecular weight is usually about 400,000 Daltons. The polysaccharide moiety joins with the protein components to form a structure known as an "albizia flower" shape, with many polysaccharide units scattered on both sides of the same polypeptide chain. It has been proved by experiments that there are three main components of gum arabic: AGP, AG and GP, which account for about 10%, 90% and 1% of the total amount of gum arabic respectively. Gum Arabic is widely used in industry, usually as binder, stabilizer, emulsifier, spice wrapping material, material to prevent sugar crystallization, stabiliz...

Embodiment 2

[0078] Embodiment 2 standard gum arabic and hyaluronic acid

[0079]The method of the present invention is also applicable to the traditional standard gum arabic without any physical and chemical modification. The standard gum arabic is in the form of coarse particles, and the biopolymer is still hyaluronic acid.

[0080] 1. Induced phase separation

[0081] The weight-average molecular weight of the standard gum arabic sample in the experiment was 560,000 Daltons, and the AGP content was 11%. The weight-average molecular weight of the hyaluronic acid sample is 1.8 million Daltons, and mixing the two sample solutions above the critical concentration will cause phase separation. Compared with thermally modified gum arabic, the molecular weight of standard gum arabic is smaller, so the phase separation critical concentration of standard gum arabic should be different from that of thermally modified gum arabic. The method of observation and GPC-MALLS detection is still used to ...

Embodiment 3

[0091] Example 3 Spray drying gum arabic and beet pectin

[0092] The method of the invention is not only applicable to heat-modified gum arabic and hyaluronic acid system, standard gum arabic and hyaluronic acid system, but also applicable to spray-dried gum arabic powder and negatively charged biopolymer—beet pectin.

[0093] 1. Induced phase separation

[0094] The weight-average molecular weight of the spray-dried gum arabic sample in the experiment was 990,000 Daltons, and the AGP content was 12%. The weight-average molecular weight of the sugar beet pectin sample is 2.6 million Daltons, and mixing the two sample solutions above the critical concentration will cause phase separation. Compared with thermally modified gum arabic and standard gum arabic, the molecular weight of spray-dried gum arabic is between the two, so the phase separation critical concentration of spray-dried gum arabic should be different from the above two. The methods of observation and GPC-MALLS d...

Abstract

The invention relates to an Arabic gum component grading method. Within the critical concentration range of phase separation, Arabic gum is mixed with one or multiple biomacromolecules in aqueous solution to form mixed aqueous solution of the Arabic gum and the biomacromolecules, and liquid-liquid phase separation is carried out on the mixed aqueous solution by means of standing, or centrifuging or standing or centrifuging under a heating condition, so that different components of the Arabic gum are graded. The method provided by the invention is a pure physical process, the natural chemical structure of the Arabic gum is not changed, even no physical combination or gathering of components is caused, and the method provided by the invention only changes proportions of the components at different grades. The graded Arabic gum products can be applicable to emulsifier, thickener, coating material, binder, capsule material and the like in the industries such as food and biological medicine.

Description

technical field [0001] The present invention relates to a method for fractionating gum arabic components, in particular to a method of mixing gum arabic and other biopolymers so that liquid-liquid phase separation occurs when the concentration is above the critical concentration, and spontaneously grading gum arabic . Fractionation allows different fractions of gum arabic to be enriched in different phases, resulting in products with different functionalities. Background technique [0002] Gum Arabic is a natural gum secreted from injured parts of plant branches, mainly from the genus Acacia of the Fabaceae, especially Acacia Senegal and Acacia Seyal. Gum Arabic is widely used in different industries, mainly as emulsifier, stabilizer, thickener, binder, capsule raw material, sugar coating raw material and pasting agent. [0003] The structure of gum arabic is very complex, including branched polysaccharide parts and protein parts. Studies have shown that gum arabic has th...
