Description
Technical field
The present invention relates to a kind of rice and breeding method thereof of diabetic patients.
Background technology
About 5,000 ten thousand people of China diabetic account for 3.5% of China's total population.Diabetic's number increases with people's's every days 3000 speed at least, and increase by 1,200,000 every year at least, and age of onset more is tending towards rejuvenation.Estimate that according to the expert China's diabetes average attack rate will reach about 11% in 2010.At present, treating diabetes mainly relies on medicine and keeps on a diet and prevents and treats.Medicine generally has side effect and can't effect a radical cure; Diet control is to patient and physiology and the psychological burden of Yan Shixin.But market in urgent need balance and stability blood sugar has obvious booster action and has the functional food of good prevention to occur treating diabetes.
Carbohydrate is the necessary energy source of human body, and daily required carbohydrate is mainly from starch based staple foods such as rice and wheats.From the angle of digestion, after starch entered human body, the overwhelming majority was digested and assimilated by enzyme degraded saccharogenesis in small intestine, sub-fraction then can be escaped the degraded of enzyme and enter large intestine, after being utilized by the large intestine microbial fermentation, finally excretes, but the former is digestible starch, and the latter is resistant starch.FAO (Food and Agriculture Organization of the United Nation) (FAO) and The World Health Organization (WHO) point out in " carbohydrate expert forum in the human nutrition " book that the United Nations in 1998 publishes: " discovery of resistant starch and progress thereof are most important achievements in the research of carbohydrate and healthy relation in recent years ".
Resistance starch content is very low in the general rice, generally is lower than 1%, and the content of commercially available high quality white rice is lower, generally is lower than 0.5%.After the edible general rice of human body, starch is very fast to be absorbed rapidly by enzyme degraded saccharogenesis, impels glycemic index sharply to raise.The diabetes patient's kind and quantity of must strictness keeping on a diet why that Here it is, one of the least possible major reason of eating sugar and digestible starch food products.
The research of rice high-resistance starch product at present concentrates on processing method, and the resistant starch product of exploitation is also generally only edible in special population as diatery supplement, does not see the research report of daily staple food RS Products Development and breed improvement.Just under this background, the invention provides a kind of rice and breeding method thereof of diabetic patients, carry out the seed selection of diabetes patient's rice special new varieties, be intended to take the strategy of diet, from source prevention diabetes patient's generation, effectively solve " having enough to eat and wear " problem of diabetes special population.
Summary of the invention
The object of the present invention is to provide a kind of rice and breeding method thereof of diabetic patients.
The rice of diabetic patients of the present invention, but it is characterized in that this rice contains resistant starch more than 5%, all the other are digestible starch.
The breeding method of diabetic patients rice may further comprise the steps:
1) collect the rice material seed, said rice material is rice varieties and the germ plasm resource through strain, mutant plant and various places that mutagenesis produces;
2) an amount of seed of reservation is standby, and all the other seeds shellings are processed into polished rice or are made ground rice, boiling, the resistance starch content after rice that mensuration is boiled or the gelatinization in the ground rice;
3) be to select index with the resistance starch content, the primary election resistance starch content is higher than 5% the pairing rice material of sample;
4) continue to plant the rice material that step 3) is screened, estimate the stability that the checking resistant starch is expressed, stable material is bred, the acquisition resistance starch content is stabilized in the rice more than 5%.
Above-mentioned stability be meant resistance starch content in the selected paddy rice between different year between (more than 2 years), season the content of (more than 2 seasons) and intersite (2 more than the place) not remarkable.
The present invention has the beneficial effect of following several respects:
1) rice of diabetic patients of the present invention because of it is rich in resistant starch, forms a kind of special construction that significantly is different from common starch, plays the release of effective delay glucose and the effect of absorption, therefore, is very suitable for diabetes patient.Because it has digestion resistant, can increase satiety, keeps a diet and control glycemic index.This rice of patients with diabetes mellitus can be had enough as normal person's breakfast, lunch and dinner, changes the phenomenon of many meal every day.After edible a period of time, steadily the postprandial blood sugar index is obvious, can progressively stop to eat blocking-up digestion medicine, feels that obviously physique takes a turn for the better, and it is significant that diabetic population is implemented dietetic treatment.
2) do not see that so far domestic and international specific aim carries out the report of the special-purpose rice of diabetes patient.No matter be to exsomatize or the body measurement glycemic index, it is huge not only to measure expense, and is difficult to organize and implement.Method described in the invention, taking with the resistant starch is index, to promoting the important directive significance of seed selection tool of the special-purpose rice of diabetes patient.
