Glycosyl hesperetin and process for producing the same and uses thereof
The present invention aims to provide a novel glycosyl hesperetin, which is significantly reduced in miscellaneous tastes characteristic of conventional products containing glycosyl hesperetin, and a method for producing the same and uses thereof; and the objects are solved by providing a glycosyl hesperetin which comprises glycosyl hesperetin in an amount of 90% or more by mass but less than 100% by mass, on a dry solid basis, but it does not substantially contain furfural, and a method for producing the same and uses thereof.
1. A glycosyl hesperetin composition, which comprises as glycosyl hesperetin α-glycosyl hesperidin and either or both of hesperidin and 7-O-β-glucosyl hesperetin in an amount of 90% by mass or more but less than 100% by mass, on a dry solid basis, wherein the content of furfural measured on GC/MS analysis is less than 200 ppb, on a dry solid basis.
2. The glycosyl hesperetin composition of claim 1 , wherein the content of 4-methoxystylene measured on GC/MS analysis is less than 30 ppb, on a dry solid basis.
3. The glycosyl hesperetin composition of claim 1 , wherein the content of α-glycosyl hesperidin is 50% by mass or more but less than 100% by mass, on a dry solid basis.
4. The glycosyl hesperetin composition of claim 1 , wherein said α-glycosyl hesperidin is α-glucosyl hesperidin.
5. The glycosyl hesperetin composition of claim 4 , wherein the content of α-glucosyl hesperidin is 60% by mass or more but 90% by mass or lower, on a dry solid basis.
6. A method for reducing the miscellaneous tastes of a glycosyl hesperetin composition comprising as glycosyl hesperetin α-glycosyl hesperidin and either or both of hesperidin and 7-O-β-glucosyl hesperetin in an amount of 90% or more by mass but less than 100% by mass, on a dry solid basis, said method comprising a step of contacting said glycosyl hesperetin composition with an inorganic reducing agent to reduce the miscellaneous tastes.
7. The method of claim 6 , wherein the content of α-glycosyl hesperidin is 50% by mass or more but less than 100% by mass to said glycosyl hesperetin, on a dry solid basis.
8. The method of claim 6 , wherein said α-glycosyl hesperidin is α-glucosyl hesperidin.
9. The method of claim 6 , wherein said inorganic reducing agent is a sulfite.
