Sweetening Effect of Characteristic Aroma Substances in Yellow Peach and Navel Orange
In order to explore the method of reducing sugar without reducing sweetness,this paper studied the influence of aroma substances on the sweetness of sucrose solution.First,7 characteristic aroma substances(nonal,decanal,decyl aldehyde,γ-caprolactone,linalool,(E)-2-pentenal,(E)-2-decenal and(E)-2-hexenol)in yellow peach and navel orange were selected and their sweetening effects were evaluated at low sucrose mass fraction(2.5%),medium sucrose mass fraction(5.0%)and high sucrose mass fraction(7.5%).Secondly,the correlation between sweetening and fruity,floral,sweet and green aromas was studied.The results showed that all the 7 aroma substances could significantly enhance the sweetness perception of sucrose at medium and high sucrose concentration(P＜0.05),and their sweetness was positively correlated with fruity aroma.
