Description

A kind of purple potato nutrient rice and preparation method
Technical field
The present invention relates to food and purple potato processing technique field, more specifically relate to a kind of purple potato nutrient rice, also relate to a kind of preparation method of purple potato nutrient rice simultaneously.
Background technology
Purple potato (Ipomoea Batatas poir) is also claimed purple sweet potato, purple sweet potato, purple sweet potato and black sweet potato, is the special kinds of sweet potato, is meant that potato meat color is the sweet potato of purple, is Convolvulaceae annual herb plant.Purple potato has the wide characteristics in region of suitable planting, all can plant in national most of areas, and wherein ground such as Hubei, Jiangxi, Sichuan, Chongqing, Guangxi, Yunnan, Shandong, Anhui, Zhejiang and Guangdong are the main producing regions of the purple planting potato of China.Sweet potato by universally acknowledged for having the natural food of anticancer health-care effect; Also be one of China's four big staple food crops; List in after wheat, paddy rice and the corn; The plantation in sweet potato year surplus China existing 400 is historical, and China's cultivated area and total output account for 70% and 85% of the world respectively, occupy first place in the world.At present, the purple potato kind of various places cultivations has: No. 6, No. 1, the purple potato in Hubei Province, Rhizoma Dioscoreae esculentae No. 18, purple No. 1 of Chongqing, wide purple 135, peaceful purple No. 4 and capital potato etc., the external kind of introducing mainly contains: mountain, river purple, American Black Ipomoea batatas, the U.S. short climing black mix potato and German black Ipomoea batatas etc.
Purple potato has the output height, purple potato anthocyanidin (Purple-Fleshed Sweet Potato Anthocyanidin generally abbreviates purple potato pigment as) content is high and the nutrition and health care value ratio such as gives prominence at characteristics.But purple potato spring and summer plantation, monolithic heavily is generally 200~800g, per mu yield 1500~4000kg, output is very high, is important crops and staple food substitute, and the crisis in food that possibly exist solution China and even the world has a very important role; Purple potato pigment content is bigger with variety variations, is generally 0.04~1.0% (in fresh weight), and the anthocyanidin content of indivedual purple potato kinds can be up to 2.0%, and purple potato pigment is present in piece root, stem, leaf and the potato skin of purple potato; Purple potato not only amount than nutritional labelings such as higher starch, protein, crude fibre, vitamin and mineral matters; Nutritive value is than higher; But also contain functional components such as organic acids such as having the purple potato anthocyanidin of multiple pharmacological effect and physiologically active, organic selenium, glycoprotein, pectin, chlorogenic acid and isochlorogenic acid, sugar ester and straight chain fatty aldehyde; Research shows that purple potato has anti-oxidant, anti-sudden change, alleviates dyshepatia, treatment angiocardiopathy, enhance immunity power and multiple physiological activity such as anticancer, and health-care effect is more outstanding.
At present, it is main that purple potato is eaten raw with aquatic foods product marketing fresh, and working research and development product are fewer.The working research of relevant purple potato is mainly reflected in four aspects: the one, and extracting purple potato anthocyanidin is purple potato pigment; Purple potato pigment not only can be used as natural edible coloring agent but also can be used as the health active composition and had been used for industries such as food, cosmetics and medicine; The domestic and international market demand is bigger, and patent 2003131605.0,200610005525.X, 200710192250.X and 200810020364.0 etc. have related to distinct methods and extracted purple potato pigment; The 2nd, process the full powder of purple potato, the full powder of purple potato both can eat separately, also was fabulous raw materials for food industry, can be used as the major ingredient or the batching of various cakes or other food; The 3rd, processing tourism and leisure food hangs down purple sweet potato chips etc. like purple French fries, purple potato dried meat, purple potato sauce and grease; The 4th, be processed into products such as purple potato wine and purple potato vinegar through fermentation.
Purple potato rice is a primary raw material, suitably allocates other food materials into, strengthens multiple nutritional components and adds the small amount of gel agent, the graininess rice made products of processing through operations such as mixing, extruder grain and dryings similar with natural rice.Patent 2000120584.6 and 200410040346.0 relates to the synthetic rice and the preparation method of the moisture raw material of gourd, fruit and vegetable, coarse cereals class raw material, rice and converted starch or konjaku flour, and these two kinds of synthetic rice's nutritive values are relatively poor; Patent 200610131657.7 relates to the synthetic rice of corn, beans, rice and the combination of bitter buckwheat; Patent 200710044124.X relates to the synthetic rice of cereal and beans combination; Patent 200710156500.4 relates to the synthetic rice with the pigment extract surface colour.The described synthetic rice of these patents does not all relate to purple potato on the one hand, is of low nutritive value on the other hand, and health care does not have or be little, so the new meter that nutritive value and health care are laid equal stress on remains further to be researched and developed.
Summary of the invention
The objective of the invention is to be to provide a kind of purple potato nutrient rice, prescription is reasonable, and nutrition is good, and is safe, and purple potato raw material is utilized fully, and the storage rate of purple potato anthocyanidin is high, and the anthocyanidin content of product is 0.06~2%; The integrated cost of product is low, and environmentally safe, and nutritional labeling relatively full nutrition is worth high.
Another object of the present invention is the preparation method who has been to provide a kind of purple potato nutrient rice, and raw material sources are wide and raw material availability is high, and integrated cost is lower, and is easy and simple to handle, and non-environmental-pollution is applicable to the scale and the industrialization production of purple potato.
