Abstract:
The invention discloses a healthy sucrose product and a method for fabricating the same. The sucrose product mainly consists of sucrose and L-arabinose, wherein sucrose has a mass percentage of 70-99.99%, and L-arabinose has a mass percentage of 0.01-30%. The method for fabricating the sucrose product mainly comprises the steps of: sufficiently mixing solid sucrose and L-arabinose crystals; or mixing solid sucrose and L-arabinose solution and then drying the resulting solution. In the present healthy sucrose product, L-arabinose is added into sucrose for suppressing invertase&#39;s activity, so that the human body&#39;s absorption of sucrose is reduced to achieve a healthy intake of sugar. In this manner, the problems of hyperglycemia, dental caries, and obesity, which otherwise may occur after the intake of sucrose, are solved.

CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the priority benefit of Chinese patent application No.2013103842030, filed on Aug. 30, 2013. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of specification. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of Invention 
         [0003]    The present invention relates to the field of foods, and particularly to a healthy sucrose product containing L-arabinose and a method for fabricating the same. 
         [0004]    2. Background of Invention 
         [0005]    With the continuous development of productivity and the continuous improvement of people&#39;s living standards, incidence of obesity, fat disease, diabetes, and cardiovascular disease continues to increase, which seriously affects human&#39;s health and longevity. The rate of obesity even reaches 45-55% in some developed regions and 10-20% in developing countries, and exhibits a trend of further development and younger age. According to analysis, the main reason lies in excessive intake of sweet food and high-fat food. The sweet taste in the sweet food mainly comes from sucrose. Upon ingestion, sucrose can be decomposed into fructose and glucose, thus increasing the level of blood glucose in the body. The excessive sucrose turns into body fat and is stored in the body, which causes obesity. Thus, there is a urgent request for a healthy sucrose. The Chinese Patent No. 200910229364.6 entitled “Novel functional healthy sugar and preparation process thereof” discloses a healthy sugar product in which sucrose and arabinose are mixed by a mass ratio of 2-98:98-2. This healthy sugar product is fabricated by melting and crystallization. The method for fabricating comprises the steps of dissolving, concentrating under vacuum, crystallizing, grinding or the like. The production process is complicated. The grain size of after grinding is difficult to control, and the state of sucrose is changed. Now, there is a request for a healthy sugar product which is simple and feasible in term of its fabricating process, can reduce or completely suppress the absorption of sucrose, and does not change sweetness and grain state of sucrose. This is not only a hot topic of researchers, but also a gospel for people who like sugar and people who suffer from high cholesterol, high blood pressure, and high blood glucose.
