Production Technology Of Special Functional Rice And Study On Exploitation Of A New Ersi

It is quite universal that disease problems including diabetes,hypertension,hyperlipemia and so on in our country. According to "medicine food homology" the idea, "functional food" opened the diet prevention disease new approach; It has the important meaning that enhance the staple food rice for the nutrition health care function to improve person's meals structure and to raise the diet health standard. In recent years, the functional rice's research also occupied the start stage as a whole, bred the special and functional rice often were high quality and low yield, disease resistance with weak(rice blast, bacterial leaf blight), narrow adaptability and so on problems. Although the resistant starch content of some functional rice is high, weak taste for direct edible, but the consumer is difficult accepts. The amylose content for Ersi rice is also high, weak taste for direct edible, but Ersi rice processing is good taste. This dissertation carries on the functional ingredient analysis of local famous Tengchong's Rice Ersi, and have selected the special and functional rice with high theγ-amino-butyric acid (GABA), resistant starch (RS) and total flavones. We have processesed the new Rice Ersi and Barley Ersi according to the definite proportion for functional rice and functional barley as well as Ersi rice. It has not only solved the problems of taste for direct edible for functional rice and barley flour, but also may enhance the functional ingredients of y-amino butyric acid, resistant starch, total flavone in Rice Ersi. Makes the following progress:1. Six rice cultivars with high functional ingredients have been examined.Through to the Rice Ersi cultivar's analysis, the average of GABA content of H20 is 13.3 mg/100g, the resistant starch is 0.779%, the flavanone content is 276.9 mg/100g; the average of GABA content of T58-6 is 12.29 mg/100g, the resistant starch is 0.67%, the flavanone content is 84.46 mg/100g. Three functional ingredients are high, is good materials to make the function Ersi and the breeding of functional rice.Moreover, GABA content of the mutantation of Liandaogu is the highest, reaches 31.65 mg/100g, Zaodaba 28.16 mg/100g, Teng 08-227.88 mg/100g, T58-8 21.46 mg/100g.This two cultivars may utilize for foundation material of the GABA breeding. Total flavone content of Tengchong Ludao is the highest, i.e 437.53 mg/100g, may do for the foundation material of the flavanone breeding and may utilize for foundation material of the flavone breeding.2. Extend benefit for T58—6 of Rice Ersi with processing type is remarkableT58-6 and T58-7 for processing special rice, although high plant type(130-137.4 cm), but the stalk is hard, the resistant to lodging, bears fat, the anti-rice blast and the bacterial leaf blight, and Rice Ersi processing with good quality, soft does not stick after cooking, lubrication mouth and good taste. Through research and extension for the standardization cultural technique, overcomes its shortcoming, yields of two cultivars are generally 400～450 Kg/667 m2 on the high elevation warm cool area in Tengchong County. The accumulation promotion areas during 2006-2008 is 99910 mu(667 m2), the average yield is 401 Kg/mu, increase 64 Kg/mu compared to 74-35(CK), the accumulation yield is 6,394,000 Kg/mu, the average increase 160 Yuan/mu, the accumulation increase the output value 15,985,600 Yuan.3. Function ingredient contents of new type Rice Ersi developed is high(1) Along with H20 unpolished rice immersion time's increase, GABA contents of Rice Ersi become high; when soaks 24h, its GABA is the highest,i.e.77.76 mg/100g. Along with H20 unpolished rice immersion time's increase, RS contents of Rice Ersi become high; when soaks 36h, RS is the highest reaches 10.13%, and it is higher (2.59%) than that of soaks 4h. Mean value of total flavone is 83.83 mg/100g. GABA and Rs as well as total flavone content of developed new Rice Ersi based on H20 germinated brown rice is higher, specially RS has achieved the functional food level, explained that the effect of H20 unpolished rice make Rice Ersi is good,it is one functional food to worth developing.(2) Processes Rice Ersi based on the mixturation of functional rice with high GABA rice according to the different proportion, increases along with rice proportion of the Diannong S-1×Haomei, GABA content of processing Rice Ersi increases, but resistant starch and total flavone content's overall change is not great, explained that joins Diannong S-1×Haomei to raise the Rice Ersi's GABA content is effective. When Diannong S-1×Haomei accounts for 50%, Rice Ersi's GABA reaches 105.6mg/100g, but Rice Ersi's physique is weak, but Rice Ersi's physique is good when occupies by Diannong S-1×Haomei the Rice Ersi's GABA also reaches 76.84 mg/100g.(3) Their change of GABA and resistant starch as well as total flavone are not big, processes the Rice Ersi to utilizate the polished rices admixture of Ersi rice (T58—6) and Gongmi No.3 according to the different proportion. The GABA content of Rice Ersi for polished rice (27.98mg/100g) is lower that of the unpolished rice; RS content average 5.4%; Total flavone content average 34.81mg/100g. There are high functional ingredient content and good taste as well as physique of Rice Ersi to admixture Ersi rice (T58—6) and Gongmi No.3. There are good Rice Ersi with the soft does not stick and the circle lubrication mouth.(4) Processes the Rice Ersi of admixture of Ersi rice and functional barley according to the different proportion; Along with functional barley permeating proportion's increase, the GABA and RS as well as the total flavone contents of Rice Ersi increases gradually, explained that when the functional barley permeating rice processing Rice Ersi, and obviously increase the functional ingredient contents of them. This is innovation spot of the dissertation. Considered Rice Ersi edible feeling in the mouth, take permeates 30% functional barley as appropriately, it's GABA content is 38.86mg/100g, RS content is 7.62%, total flavone content 54.82mg/100g. It is one kind of good functional Rice Ersi with higher three functional ingredients.
