Abstract

PURPOSE:To produce a syrup containing a large amount of branched oligosaccharide having caries-preventing effect, extremely economically, by the industrial process based on the reverse synthesis with an enzyme. CONSTITUTION:An aqueous solution of glucose having a solid concentration of >=50% is made to react with an enzyme capable of condensing a saccharide (e.g. glucoamylase) to produce a branched oligosaccharide in the aqueous solution. The sugar syrup produced by the above process is a mixture containing glucose, maltose, etc. as well as branched oligosaccharides such as isomaltose, panose, isomaltotriose, etc. If necessary, the saccharides other than the branched oligosaccharides are separated and removed e.g. by the organic solvent treatment, to obtain a syrup of branched oligosaccharide having high concentration.

Recently, there has been a tendency to avoid sweeteners such as sugar from the viewpoint of preventing tooth decay, and branched oligosaccharides such as isomaltose are attracting attention as an alternative sweetener. However, as a method for industrially and economically mass-producing these branched oligosaccharides has not yet been established, isomaltose and the like are currently only sold as expensive reagents and are not commonly used in food products. has not yet been reached.

Furthermore, it is known that in the conventional glucose production process, glucoamylase and the like cause a glucose retrosynthesis reaction as well as saccharification, and small amounts of isomaltose and panose produce so-called branched oligosaccharides. The amount produced is usually around 5% of the sugar solid content, but
From the viewpoint of glucose production, the production of such branched oligosaccharides is not desirable, and therefore efforts have been made to suppress their production as much as possible. It is also known that when starch is hydrolyzed with acid at high temperatures, a compatibility reaction occurs and sugars having α-1,6 bonds are produced. However, in this case, the conversion rate to branched oligosaccharides is extremely low, and since the conditions are extremely extreme, there are many products due to side reactions, so this method can be practically used as a means for producing branched oligosaccharides. There is almost no possibility.

In the present invention, an enzyme having a saccharide condensation action is applied to a glucose aqueous solution having a solid content concentration of 50% or more to produce branched oligosaccharides in the aqueous solution, and further, if necessary, saccharides other than branched oligosaccharides are separated and removed. This is a method for producing syrup containing a large amount of branched oligosaccharides. The term "branched oligosaccharide" as used herein is a general term for oligosaccharides having α-1,6 bonds, such as isomaltose, panose, and isomaltotriose.

According to the research conducted by the present inventors, it has been found that the amount of branched oligosaccharides produced from a glucose solution by a compatible composition reaction increases as the glucose solid content concentration of the glucose aqueous solution used as a substrate increases. That is, to explain this using Figure 1, when glucoamylase is applied to glucose solutions with various solid content concentrations, as the reaction time progresses,
The amount of branched oligosaccharide produced gradually reaches a certain equilibrium state (after about 3 days) for each solid content concentration. At this time, for example, if the solid content concentration is 50%, the amount of branched oligosaccharides produced will be in equilibrium at about 30% (as solid content), but
As the solid concentration of the substrate increases, the equilibrium state shifts to a higher value, and when an 85% glucose solution is used, the amount of branched oligosaccharides produced reaches around 60%, and an equilibrium state is reached. The above equilibrium state seems to have a certain level depending on the concentration of the substrate used. For example, after reaching the equilibrium state (the amount of branched oligosaccharide produced is around 50%) in a reaction with a substrate concentration of 75%, the substrate is diluted and the concentration When the concentration was 50%, it was observed that the equilibrium state changed to a level where the substrate concentration was 50% (the amount of branched oligosaccharide produced was about 30%).

From these facts, it is clear that in order to obtain branched oligosaccharides in high yield, it is desirable to use a glucose solution with a high solid content concentration. Therefore, in the present invention, the glucose solution used as a substrate needs to have a high solid content concentration, and is preferably 50% or more, preferably 60% or more. In a glucose solution with a solid content concentration of 50% or less, the production of branched oligosaccharides rapidly decreases, which is economically disadvantageous and therefore inconvenient.

In the present invention, such a highly concentrated glucose solution is used as a substrate, and an enzyme having an M-class condensing action, such as glucoamylase, is allowed to act on this to proceed with the reaction. Reaction conditions, such as reaction temperature and pH, may be in accordance with the conditions under which each enzyme is normally used, and no particularly special conditions are required. Glucoamylase is most suitable as the enzyme to be used because of its ease of availability. Furthermore, it goes without saying that it is preferable that the glucose used as the substrate be of high purity.

The enzyme reaction may be carried out batchwise or continuously using a column. During the reaction, the concentration of the substrate gradually decreases due to the condensation reaction of glucose due to the compatible composition.
Accordingly, the equilibrium level of branched oligosaccharide production tends to decrease with substrate concentration. However, since the decrease is very slight, it is often not a practical disadvantage, but if necessary, the concentration can be kept constant by appropriately supplying glucose to the substrate aqueous solution during the reaction, and the level of branched oligosaccharide production can be reduced. can also be maintained.

Conversely, depending on the purpose, the equilibrium level of branched oligosaccharide production may be arbitrarily changed by appropriately increasing or decreasing the substrate concentration during the reaction.

The concentration of the glucose solution used as a substrate is 80% or more, especially 85%.
If the temperature exceeds 100%, crystals will precipitate in the liquid, which requires caution during operation, but these often disappear during the reaction and do not interfere with the operation. The reason why the crystals disappear during the reaction is that, in addition to the decrease in the substrate concentration due to the condensation reaction of glucose, the formation of amorphous isomaltose prevents the crystallization of other sugars.

このようにして分岐オリゴ糖を多く含む糖液が得られる
が、その糖組成の一例は第1表に示すとおりである。
In this way, a sugar solution containing a large amount of branched oligosaccharides is obtained, and an example of the sugar composition is shown in Table 1.

This seems to be the same for those with 4 or more leaves, and it is clear that many branched oligosaccharides are produced in the reaction solution. In addition, the amount of DP2 produced reaches equilibrium at about 30%,
It is observed that DP3, DP4, etc. increase as the reaction time is extended. From this, it is also possible to produce branched oligosaccharides with different compositions by appropriately controlling the reaction conditions.
