Problems solved by technology

Among them, octenyl succinic esterified starch, one of the esterified starches, has excellent emulsifying ability, but its emulsifying stability is very low in a highly diluted system, so it is not suitable for long-term storage
In addition, acetate-esterified starch in which acetate is bonded to starch is also sold, but it has no emulsification stability and can only be used for aging resistance and viscosity stability.

Embodiment 1）

[0077] (Example 1) - demethylation treatment (pH12), acetic esterification treatment (20%) -

[0078] Using okara produced during the production of isolated soybean protein as a raw material, add water to it, and adjust the pH to 5 with hydrochloric acid. Then, the water-soluble soybean polysaccharides were extracted by heating at 125° C. for 2 hours in an autoclave. After the extraction, centrifugation (5,000×g, 10 minutes) was performed to separate into a supernatant mainly containing water-soluble soybean polysaccharides and a precipitate. Sodium hydroxide was added to the supernatant to adjust the pH to 12. Then, it heated at 60 degreeC for 60 minutes, and performed demethylation process. The precipitate produced by heating was removed, and the pH was adjusted to 5.0 with hydrochloric acid to remove the precipitate. Thereafter, desalination treatment was performed by electrodialysis, the aqueous solution of water-soluble soybean polysaccharides was concentrated to 10Bx,...

Embodiment 2）

[0080] (Example 2) - demethylation treatment (pH11), acetic esterification treatment (10%) -

[0081] In the same manner as in Example 1, water-soluble soybean polysaccharides were extracted, demethylated and acetic esterified. Here, the demethylation treatment adjusted the pH to 11, and the acetic acid esterification treatment used 10% by weight of acetic anhydride relative to the solid content. The obtained "water-soluble soybean polysaccharide B" was analyzed similarly to Example 1.

Embodiment 3）

[0082] (Example 3) - demethylation treatment (pH10), acetic esterification treatment (5%) -

[0083] Water-soluble soybean polysaccharides were extracted in the same manner as in Example 1, and subjected to demethylation treatment and acetic esterification treatment. Here, the demethylation treatment made pH 10, and the acetic anhydride treatment used 5% by weight of acetic anhydride relative to the solid content. The obtained "water-soluble soybean polysaccharide C" was analyzed similarly to Example 1.

Abstract

The purpose of the present invention is to provide a natural polymeric emulsifier improved in so-called "emulsifying power", said natural polymeric emulsifier being capable of forming, even by the addition thereof in a small amount, an oil-in-water emulsion which has a small emulsified particle diameter and a uniform particle size distribution and which rarely suffers from the aggregation or coalescence of emulsified particles even when has undergone heating, long-term storage, aging or the like. [Solution] The purpose can be achieved by using water-soluble soybean polysaccharides which have a methyl ester content of 30% or below relative to the uronic acids and an acetate content of 1wt% or higher in terms of free acetic acid and relative to the water-soluble soybean polysaccharides. The water-soluble soybean polysaccharides can be manufactured by subjecting raw material water-soluble soybean polysaccharides to methyl ester removal treatment and thereafter acetate-forming esterification treatment.

Description

technical field [0001] The present invention relates to modified water-soluble soybean polysaccharides. Specifically, it relates to water-soluble soybean polysaccharides having excellent emulsifying ability and emulsification stability compared with conventional water-soluble soybean polysaccharides. In particular, it relates to water-soluble soybean polysaccharides which are suitable for exhibiting high emulsifying ability and emulsification stability, which are characterized by low methyl ester content and moderate acetate content, and furthermore, water-soluble soybean polysaccharides. An emulsifier with sugar as an active ingredient, an oil-in-water emulsion formed using the emulsifier, and the application of water-soluble soybean polysaccharides in the preparation of the emulsifier and the oil-in-water emulsion. Background technique [0002] For polymer emulsifiers, even if the emulsion is highly diluted, it can maintain the emulsified state without being destroyed, an...
