A kind of health substitution sugar and the method with liquid state fermentation technology preparation health substitution sugar
Technical field
The present invention relates to food technology fields, prepare more particularly to a kind of health substitution sugar and using liquid state fermentation technology
The method of health substitution sugar.
Background technique
Sugar is one of important substance for the survival of mankind, is one of big main nutrients of human body three, is human body thermal energy
Main source." sugar " generally eaten typically refers to sucrose.About 4 calories of heat contained by every gram of sugar, if intake is excessive
And can not consume in time, extra heat will be converted to fat.In addition, food, drink containing addition sugar absorb excessive meeting
Blood glucose rapid increase is enabled, insulin in blood is caused to increase;Insulin can enable body efficiently depot fat, cause fertilizer
It is fat, it will increase the risk for suffering from chronic disease such as cardiovascular disease.So some experts think: sugar is than cigarette and alcoholic drink pair
The harm of human body is also big.World Health Organization's investigation discovery, it is hard that sugar intake excessively will lead to heart disease, hypertension, blood vessel
Change disease and cerebral hemorrhage, diabetes etc..The evil of thermophilic sugar, more than smokes.Therefore, the World Health Organization proposes " to guard against in the whole world in nineteen ninety-five
The new slogan of sugar ".With the improvement of living standards, people are to high heating values such as addition sucrose, glucose and have certain side effect
Sugar is not welcome increasingly.And sucrose uses long-standing, peculiar sense of taste of the people especially children to sucrose sweet taste
Dependence is difficult to shake.How not only to have kept the habitual sucrose taste of people, but also benefited from functional sugar low sugar, nutrition etc.
New concept of health, and a problem of puzzled food service industry.
L-arabinose (L-arabinose) is also known as arabinose, is able to suppress the absorption of sucrose, 3.5 are added in sucrose
The ratio of %, is able to suppress the absorption of 60 ~ 70 % sucrose of human body, and long-time service can control blood glucose rise therefore can inhibit fertilizer
It is fat, prevent disease relevant to hyperglycemia;Prevent constipation promotes bifidobacterium growth;There is the function for changing skeletal muscle fibre ingredient
Effect influences the growth of abdominal adipose tissue to glycoxidative by dominating glycolysis, and the change of this Muscle fiber density may have
Improve the effect of diabetes B.
Fructose is a kind of refine from various fruit and cereal, new carbohydrate all natural, sweet taste is strong, because not easily leading to high blood
Sugar is also not susceptible to fat accumulation and gets fat, and will not more generate saprodontia, and is recognized by more people.The sugariness of fructose is
1.8 times of sucrose are the highest sugar of sugariness in all natural sugars, so the intake of fructose is only under same sweetness standard
For the half of sucrose.And compared with synthesis is for sugar, fructose trophism with it is then more reliable in safety.It can be said that fructose
It is current most safe, most healthy one of sugar known in the world.
Xylose is a component of xylan, is widely present in plant.Xylose is not digested absorption, without energy value,
Can meet love to the maximum extent and eat the needs of sweets worries the person of getting fat again;Edible xylose can improve the microbial environment of human body, mention
The immunocompetence of high body;Xylose is not utilized by Institute of Micro-biology in oral cavity, is had the part physiological function of dietary fiber, can be reduced
Serum cholesterol, prevention intestinal cancer etc.;The compatibility of xylose and food is fine, and a small amount of xylose is added in food, just can embody very
Good health-care effect;Xylose is taken in simultaneously with calcium, human body can be improved to the absorptivity and retention rate of calcium, moreover it is possible to prevent constipation.
With the improvement of living standards, the health that people are increasingly careful in one's diet, thus develop it is a kind of it is novel, be able to satisfy
The sweetener that people's mouthfeel is not easy to cause a variety of diseases again is extremely urgent.Currently, most of use functional sugar alcohol such as xylitol, wheat
The parts such as bud sugar alcohol substituting saccharose, but since people are in functional sugar alcohols such as edible xylitol, maltitols, it may appear that diarrhea,
The adverse consequences of abdominal distension, therefore its amount and edible crowd are partially limited.The prior art passes through melting or vacuum mostly
Several sugar are mixed with functional sugar by the methods of concentration, but such method cost of material is high, is not easy expanding production;Utilize plant
Raw material prepares arabinose, fructose etc. and usually requires the chemical methodes such as sour water solution in process of production, not only complex process, and
There is the potential risk for introducing chemical component.
