The healthy method substituting sugar.
Background technology
Sugar is one of important substance of depending on for existence of the mankind, is one of big main nutrients of human body three, is human body heat energy
Main source.General " sugared " eaten typically refers to sucrose.Heat contained by every gram of sugar about 4 calories, if picked-up excess
And cannot consume in time, unnecessary heat will change into fat.Additionally, containing adding the food of sugar, beverage picked-up too much meeting
Make blood glucose rapid increase, cause insulin in blood to increase;Insulin can make health efficiently depot fat, causes fertilizer
Fat, the risk suffering from chronic disease such as cardiovascular disease can be increased.So some expert thinks: sugar is than cigarette and alcopop pair
The harm of human body also wants big.World Health Organization's investigation finds, sugar is taken in and heart disease, hypertension, blood vessel too much can be caused hard
Change disease and cerebral hemorrhage, diabetes etc..Addicted to the evil of sugar, more than smoking.Therefore, World Health Organization (WHO) proposes " whole world ring in nineteen ninety-five
Sugar " new slogan.Along with growth in the living standard, people are to adding the high heating value such as sucrose, glucose and having certain side effect
Sugar is not welcome.And the use of sucrose is long-standing, the people especially children peculiar sense of taste to sucrose sweet taste
Dependency is difficult to shake.The most both keep people's habitual sucrose taste, benefit from again functional sugar low sugar, nutrition etc.
New concept of health, is also a problem of puzzled food service industry.
L-arabinose (L-arabinose) is also known as pectose, it is possible to the absorption of suppression sucrose, adds 3.5 in sucrose
The ratio of %, it is possible to the absorption of suppression human body 60 ~ 70 % sucrose, therefore life-time service can control blood glucose rising can suppress fertile
Fat, prevent the disease relevant to hyperglycemia;Constipation, promotes bifidobacterium growth;Change the merit of skeletal muscle fiber composition
Effect, may be had to the glycoxidative growth affecting abdominal adipose tissue, the change of this Muscle fiber density by domination glycolysis
Improve the effect of type 2 diabetes mellitus.
Fructose is a kind of refinement from various fruit and corn, All Pure Nature, new saccharide that sweet taste is strong, because not being easily caused high blood
Sugar, is not easy to occur athero to get fat, more will not produce dental caries, and be recognized by more people.The sugariness of fructose is
1.8 times of sucrose, are the sugar that in all natural sugar, sugariness is the highest, so under same sweetness standard, the intake of fructose is only
Half for sucrose.And with synthesis for compared with sugar, fructose is the most more reliable on trophism with safety.It can be said that fructose
Be at present the most in the world known to one of the safest, the most healthy sugar.
Xylose is a component of xylan, is widely present in plant.The most digested absorption of xylose, does not has energy value,
Can meet to greatest extent and like that eating sweets worries again the demand of the person of getting fat;Edible xylose can improve the microbial environment of human body, carries
The immunocompetence of high body;Xylose is not utilized by Institute of Micro-biology in oral cavity, possesses the part physiological function of dietary fiber, it is possible to decrease
Serum cholesterol, prevention intestinal cancer etc.;Xylose is fine with the compatibility of food, adds a small amount of xylose, just can embody very in food
Good health-care effect;Xylose is taken in calcium simultaneously, can improve human body to the absorbance of calcium and retention rate, moreover it is possible to prevent constipation.
Along with growth in the living standard, the health that people are increasingly careful in one's diet, thus develop a kind of novel, can meet
People's mouthfeel is difficult to again cause the sweeting agent of multiple disease extremely urgent.At present, major part uses functional sugar alcohol such as xylitol, wheat
The part substituting saccharoses such as bud sugar alcohol, but owing to people are when functional sugar alcohol such as edible xylitol, maltose alcohols, it may appear that diarrhoea,
The adverse consequences of abdominal distention, therefore its amount and edible crowd are partly limited.Prior art is mostly by melted or vacuum
Several sugar are mixed with functional sugar by the methods such as concentration, but this kind of method cost of material is high, is difficult to expanding production;Utilize plant
Raw material is prepared arabinose, fructose etc. and is typically required the chemical methodes such as acid hydrolysis, not only complex process in process of production, and
