A kind of potato rice and processing method thereof
Technical field
The present invention relates to a kind of rice processing method, particularly a kind of potato rice and processing method thereof.
Background technology
Potato nutritious, is called as out of this world food.For a long time, many countries are used potato as staple food resource.
But one of approach of processing staple food with rice, potato is the independent boiling method of rice.In this method, only use rice, do not use potato, can not make potato rice, to drive the consumption of potato.Two of the approach of processing as staple food is the independent boiling methods of potato, is about to the fresh potato peeling after cleaning or does not remove the peel, more whole potato is directly steamed to (boiling) ripe rear eating.There are many shortcomings in this method: the one, in the time of the direct boiling of fresh potato, because Potato Cultivars difference, Individual Size difference are large, be difficult to the boiling method of standard by the individual boiling simultaneously of different potatos slakings; The 2nd, due to the individual heat-resistant quality difference of potato, in digestion process, the easy gelatinization of some individualities, starch granules are separated out, and cause organoleptic quality to decline, degradation; The 3rd, in digestion process, potato is easily ftractureed, and causes that nutriment wherein runs off; The 4th, this boiling method, can not invest market by potato staple food, is difficult to expand the market of potato.Three of the approach of processing as staple food is that potato and rice close cooking method.By whole fresh potato and together boiling of rice after peeling.The major defect of this method: the one, the slaking simultaneously of rice and potato; The 2nd, rice is bonded in potato surface, is not easy to take food; The 3rd, when the potato after peeling is dealt with improperly, often easily variable color, affects aesthetic quality; The 4th, after potato starch particle is separated out, the outward appearance muddle of potato rice, unlimpid.
The common shortcoming of above three approach is also, with fresh potato making potato rice, also be subject to potato and supply seasonal restriction, can not the anniversary potato be processed, cause potato rice process technology to be difficult to promote, the consumption of potato is difficult to expand, and has seriously restricted the benign development of Potato Industry.
Summary of the invention
Technical problem to be solved by this invention is, for the existing deficiency of cooing staple food processing method of rice, potato, provide that a kind of rice synchronizes with potato that slaking, potato ball are not ftractureed, nondiscolouring, farina are not separated out, potato rice non-stick pan, the non-discoloring potato rice of the bottom of a pan rice and processing method thereof.
For solving the problems of the technologies described above, the first technical scheme of the present invention is: a kind of potato rice, and it is processed by following raw materials according by weight percentage:
Get and eluriate clean rice 30%-40%;
Wash potato piece or fourth 20%-30% after surface starch and reduced sugar off;
Clear water 40%-50%.
For solving the problems of the technologies described above, the second technical scheme of the present invention is: a kind of processing method of potato rice, it comprises the following steps:
1) after fresh potato is cleaned, is removed the peel, rapidly potato is placed in to clear water, again potato is cut into (0.4-0.8) cm x (0.4-0.8) centimetre big or small potato piece or fourth, and potato piece or fourth are placed in rapidly to clear water, rinse starch and the reduced sugar on potato piece or fourth surface with clear water;
2) after rice cooker is cleaned, is dried, be coated with last layer edible oil in rice cooker bottom, get by weight percentage again and eluriate clean rice 30%-40%, wash potato piece or fourth 20%-30% after starch and reduced sugar off, clear water 40%-50% puts into rice cooker, after mixing, together boiling, until potato piece or fourth and rice boil.
For solving the problems of the technologies described above, the third technical scheme of the present invention is: a kind of processing method of potato rice, is characterized in that comprising the following steps:
1) dehydrated potato potato piece or fourth are soaked to 3-5 hour in clear water, the size that makes to soak rear potato piece or fourth is (0.4-0.8) cm x (0.4-0.8) centimetre, and rinses starch and the reduced sugar on potato piece or fourth surface with clear water;
2) rice cooker is cleaned, dried, be coated with last layer edible oil in rice cooker bottom, get by weight percentage again and eluriate clean rice 30%-40%, wash potato piece or fourth 20%-30% after starch and reduced sugar off, clear water 40%-50% puts into rice cooker, after mixing, together boiling, until potato piece or fourth and rice boil.
Further being improved to of such scheme, after described potato piece or fourth and rice boil, insulation 5-10 minute.
Further being improved to of such scheme, described potato carries out cutting with stainless steel knife.
Further being improved to of such scheme, described edible oil is edible vegetable oil.
Fresh potato for the present invention (or dehydrated potato) and rice are that Raw material processing goes out potato rice, and in this potato rice boiling process, rice synchronizes with potato that slaking, potato ball are not ftractureed, nondiscolouring, farina are not separated out, potato rice non-stick pan, the bottom of a pan rice nondiscolouring.Below the principle that the present invention is obtained to above-mentioned effect is described:
(1) potato is synchronizeed the principle of slaking with rice
Rice starch is different from the gelatinization point of farina, and the gelatinization point of rice is higher than the gelatinization point of potato; And dry rice also will absorb the moisture ability gelatinization in a large amount of external worlds at a certain temperature.Make dry rice and the synchronous slaking under same condition of moistening potato, must guarantee potato ball size to fit, the ratio of the moisture of rice, potato ball is suitable, and acid extraction is appropriate.
(2) prevent the principle that potato cracking, starch are separated out
Fresh potato water content is high, and gelatinization point is low, and heating-up temperature is too high or the heat time is long, can be all the excessive gelatinization of potato and ftractureing, and causes starch to be separated out, and causes potato ball form imperfect, and it is unlimpid that rice seems, aesthetic quality reduces.Therefore, to, in the boiling process of potato rice, adopt rational brew temperatures and time to rice and potato, both ensure the lucky slaking of rice and potato, guarantee that again potato ball can not ftracture, starch can not be separated out and be affected the aesthetic quality of potato rice.
