Description

A kind of processing method of potato rice
Technical field
The present invention relates to a kind of rice processing method, particularly a kind of processing method of potato rice.
Background technology
Potato nutritious, is called as out of this world food.For a long time, potato is used as staple food resource by many countries.
But, be the independent boiling method of rice by one of approach of rice, Potato ring rot bacteria staple food.Only use rice in this method, do not use potato, potato rice can not be made, to drive the consumption of potato.As staple food processing approach two are the independent boiling methods of potato, be about to the fresh potato peeling after cleaning or do not remove the peel, more whole potato is directly steamed (boiling) ripe rear edible.There is many shortcomings in this method: one is when the direct boiling of fresh potato, because Potato Cultivars is different, Individual Size difference is large, is difficult to the boiling method of standard by different potato individual boiling simultaneously slaking; Two is that in digestion process, the easy gelatinization of some individualities, starch granules are separated out, and cause organoleptic quality to decline, degradation because the individual heat-resistant quality of potato is different; Three is in digestion process, and potato is easily ftractureed, and causes nutriment wherein to run off; Four is this boiling methods, potato staple food can not be invested market, is difficult to the market expanding potato.As staple food processing approach three be that potato and rice close cooking method.By the whole fresh potato after peeling and rice together boiling.The major defect of this method: one is that rice and potato can not slakings simultaneously; Two is that rice is bonded in potato surface, is not easy to take food; Three is potatos after peeling when dealing with improperly, and often easily variable color, affects aesthetic quality; Four is after potato starch particle is separated out, and the outward appearance of potato rice is muddled, unlimpid.
The common drawback of above three approach is also, potato rice is made with fresh potato, also be subject to potato and supply seasonal restriction, anniversary potato can not be processed, potato rice process technology is caused to be difficult to promote, the consumption of potato is difficult to expand, and seriously constrains the benign development of Potato Industry.
Summary of the invention
Technical problem to be solved by this invention is, do the deficiency of staple food processing method for existing rice, potato, the slaking synchronous with potato of a kind of rice be provided, potato ball does not ftracture, nondiscolouring, farina are not separated out, the non-discoloring potato rice of potato rice non-stick pan, 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 processing method of potato rice, it comprises the following steps:
1) by after fresh potato cleaning, peeling, rapidly potato is placed in clear water, again potato is cut into potato block or the fourth of (0.4-0.8) cm x (0.4-0.8) centimetre size, and potato block or fourth are placed in clear water rapidly, starch and the reduced sugar on potato block or fourth surface is rinsed with clear water;
2) after rice cooker being cleaned, drying, last layer edible oil is coated with bottom rice cooker, get by weight percentage again and eluriate clean rice 30%-40%, wash the potato block after starch and reduced sugar or fourth 20%-30% off, clear water 40%-50% puts into rice cooker, after mixing, together boiling, until potato block or fourth and rice boil.
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, is characterized in that comprising the following steps:
1) dehydrated potato potato block or fourth are soaked 3-5 hour in clear water, after making immersion, the size of potato block or fourth is (0.4-0.8) cm x (0.4-0.8) centimetre, and rinses starch and the reduced sugar on potato block or fourth surface with clear water;
2) rice cooker cleaned, dry, last layer edible oil is coated with bottom rice cooker, get by weight percentage again and eluriate clean rice 30%-40%, wash the potato block after starch and reduced sugar or fourth 20%-30% off, clear water 40%-50% puts into rice cooker, after mixing, together boiling, until potato block or fourth and rice boil.
Being improved to further of such scheme, after described potato block or fourth and rice boil, insulation 5-10 minute.
Being improved to further of such scheme, the stainless steel knife of described potato carries out cutting.
Being improved to further of such scheme, described edible oil is edible vegetable oil.
The present invention's fresh potato (or dehydrated potato) and rice are that Raw material processing goes out potato rice, and in this potato rice boiling process, rice slaking synchronous with potato, potato ball are not ftractureed, nondiscolouring, farina are not separated out, potato rice non-stick pan, the bottom of a pan rice nondiscolouring.Below principle the present invention being obtained to above-mentioned effect is described:
(1) principle of potato slaking synchronous 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 the rice of drying also will absorb the gelatinization of a large amount of extraneous moisture ability at a certain temperature.Make dry rice and the synchronous slaking under identical 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) principle that potato is ftractureed, starch is separated out is prevented
Fresh potato water content is high, and gelatinization point is low, and heating-up temperature is too high or the heat time is long, and can be all the excessive gelatinization of potato and ftracture, cause starch to be separated out, cause potato ball form imperfect, rice seems unlimpid, and aesthetic quality reduces.Therefore, in the boiling process of potato rice, rational brew temperatures and time to be adopted to rice and potato, both ensure rice and the lucky slaking of potato, guarantee that again potato ball can not ftracture, starch can not be separated out and affect the aesthetic quality of potato rice.
(3) principle of the coking variable color of polyphenols oxidation stain and reduced sugar in inhibition of potato block
Polyphenols containing certain easy oxidation stain in potato tissue.Therefore, the potato of peeling, cutting be put into water in time with starvation, prevent the polyphenols oxidation stain in potato ball; Also the reduced sugar on potato block surface to be cleaned up, prevent reduced sugar in the bottom of a pan coking variable color.
(4) the rehydration principle of dehydrated potato block
After potato ball dehydration, although the supply time of raw potatoes can be extended, meet the four seasons needs of consumer.But the necessary rehydration of dehydrated potato, the rice of ability boiling one-tenth quality the same as fresh potato.Therefore, the dehydrated potato block of the present invention's employing first suitably rehydration before boiling.
Compared with prior art, the present invention has the following advantages:
Existing conventional art mainly contains three kinds: conventional art 1 is the independent boiling method of rice; Conventional art 2 is the independent boiling methods of potato; Conventional art 3 is that potato and rice close cooking method.The present invention compares with conventional art 1, has nutritious advantage, and containing abundant lysine, tryptophan in potato, these are all lack in Cereal grain.By potato and rice together boiling become potato rice, enriched lysine and tryptophan, improve the biological value of protein in rice, can promote that human body is to effective utilization of rice protein; Potato also containing abundant carrotene and vitamin C, improves the nutritive value of rice; In addition, potato rice makes rice have the delicate fragrance of potato, enhances the mouthfeel of rice; Compared with conventional art 2, the present invention makes potato rice, and can drive with rice is crowd's food potato of staple food, drives potato as the consumption of staple food.Compared with conventional art 3, the present invention makes potato rice, and potato and rice can synchronously slakings; Potato is not ftractureed; Potato nondiscolouring; Rice non-stick pan.In addition, the present invention also can use dehydrated potato, makes raw potatoes by the restriction of producing season, can not obtain year-round supply; By the consumption of potato rice, the consumption of potato can also be driven, expand food source, alleviate crisis in food.
