Embodiment 1

[0018] Embodiment 1: the glycemic index of special rice for diabetics

[0019] The glycemic index of 15 representative common rice and rice noodle products in different ecological regions in my country is shown in Table 1. The glycemic index of ordinary rice, whether it is hot rice or its products, is very high, that is, the glycemic index of ordinary rice is higher than 80, the rice noodle product is relatively higher, and the glycemic index of high-quality rice is higher, about 100, which belongs to Typical high glycemic index foods (Table 1). The glycemic index of the diabetes-specific rice LGI-R1 described in the present invention is significantly lower, lower than 50, of which the hot rice is only 39, and the rice noodle is 41.

Embodiment 2

[0022] Example 2: Cultivate rice with a glycemic index lower than 50 for diabetes and its effects from mutant plants

[0023] Using 9311, the main medium indica rice variety in my country, as the material, through chemical mutagenesis, 30,000 second-generation mutant plants were constructed in 2004. While retaining part of the seeds, use STATAKE brown rice machine and rice polishing machine to dehull and process into polished rice, cook mature rice in a rice cooker according to the water-to-rice ratio of 1.5:1, sample hot rice kept at 50 degrees, and measure the glycemic index (the glycemic index is Refers to the rate and extent of the increase in blood glucose concentration after the human body eats hot rice. When measuring the glycemic index of hot rice, glucose is first selected as the standard food, and its glycemic index is stipulated to be 100. Compared with glucose, the effect of hot rice on The influence of blood sugar, obtain the glycemic index of hot rice), primary s...

Embodiment 3

[0024] Example 3: In Vitro Digestive Resistance of Rice Special for Diabetes

[0025] Using LGI-R1 rice for diabetes as a material, compared with high-quality rice (Northeast fragrant rice), the digestion characteristics were compared under in vitro conditions, and the results are shown in figure 1 . Depend on figure 1 It can be seen that the special rice for diabetes of the present invention has remarkable digestion resistance, and shows significantly low digestion rate and digestion speed, that is, after 1.5-2.0 hours of digestion, 90% of high-quality rice has been quickly digested and starch is converted into sugar, while the special rice for diabetes LGI-R1 digested only about 50%, and the rate of starch hydrolysis was significantly slower.

Abstract

The present invention relates to a method of breeding paddy special for diabetic. The method comprises steps of collecting paddy material seeds, preserving appropriate amount of standby seeds, other seeds being performed with a shelling process to obtain polished rice or rice flour, cooking the rice or rice flour, and measuring the glycemic index of the cooked rice or gelatinized rice flour; firstly selecting the paddy materials corresponding to the samples with the glycemic index below 50 to plant, evaluating and validating the expression stability of the low glycemic index, breeding the materials having a stable glycemic index that below 50, and obtaining the rice having a stable glycemic index that below 50. The paddy special for diabetic of the present invention relates to a low glycemic index food, stays for a long time in the stomach and intestine and has a low absorptivity. The dextrose in the paddy special for diabetic can be released slowly, when the dextrose is in blood, the peak value is low and the descending rate is reduced too, postprandial blood sugar effect can be improved greatly, therefore, the present invention is important to perform dietotherapy for diabetic.

Description

technical field [0001] The invention relates to a method for cultivating special rice for diabetes. Background technique [0002] Chinese residents have traditionally used grains as their staple food, but now the consumption of grains continues to decline, and the intake of high-fat and high-protein foods such as meat and eggs continues to rise. The increasing westernization of lifestyle and eating habits and the aging of the population have had a serious impact on the physical fitness of the nation and led to a major shift in the spectrum of human disease. The proportion of chronic lifestyle unhealthy diseases such as diabetes, cardiovascular disease, obesity, hyperlipidemia, and high blood pressure continues to rise, and has become a major global public health problem in this century. Some people predict that by 2015, lifestyle diseases will become the number one killer of human beings. Among these diseases, the incidence of diabetes has increased significantly. It is e...
