Abstract
The invention discloses a processing method of germ-remaining rice, which comprises the following steps: rough rice, cleaning, rice hulling, paddy separation, brown rice selection, brown rice tempering, multi-step whitening, polishing, germ rice grading, color selection, finished product warehousing, metering and packaging and finished product germ rice. The production of the germ-retaining rice meets the requirements of people on food nutrition and health care; in addition, the germ is reserved when the germ-remaining rice is processed, so that the rice yield is improved, the germ-remaining rate of the obtained germ-remaining rice is higher than 80%, and the nutrition in the rice germ can be well reserved, so that the germ-remaining rice has a wide market prospect, the health care consciousness of people is improved by strongly advocating and promoting the germ-remaining rice, and the nutritional structure of daily life is perfected.
Description
Technical Field
The invention relates to the technical field of rice processing, in particular to a processing method of germ-remaining rice.
Background
Rice, the most prominent and longest kind of grain in the genus of rice, is native to China. Is one of the main grain crops in the world. The rice seeding surface of China accounts for 1/4 of food crops all over the country, and the yield accounts for more than half. The rice has various eating methods, such as rice, rice porridge, rice cake, rice wine and the like. Besides being edible, the rice can also be used as industrial raw materials for brewing wine and making sugar, and the rice husks and rice straws can be used as feed. Has wide application.
The germ-remaining rice is rice with the germ-remaining rate of more than eighty percent. The embryo is an important component of rice, is rich in fat, protein, vitamin B1 and the like, and has high nutritional value. But are easily released. In order to obtain the polished rice, the rice is repeatedly rolled, bran is removed, and simultaneously, rice embryos are also removed, so that a lot of nutrition is lost, the rice embryos are rich in high-quality protein, glutathione, high-quality fat, macroelements of calcium, magnesium, trace elements of zinc and other mineral substances, so that the nutrition value of the germ-remaining rice is higher than that of common rice, and the edible germ rice is beneficial to human health.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the processing method of the embryo-remaining rice, the embryo-remaining rate of the obtained embryo-remaining rice is higher than 80%, the nutrition in the rice embryo can be well reserved, the process is simple, the working efficiency is improved, and the method is easy to realize.
In order to achieve the aim of the invention, the invention adopts the specific scheme that:
a processing method of germ-remaining rice, comprising the following steps: rough rice, cleaning, rice hulling, paddy separation, brown rice selection, brown rice tempering, multi-step whitening, polishing, germ rice grading, color selection, finished product warehousing, metering and packaging and finished product germ rice.
Further, brown rice with germ retention rate of more than 90% is selected as raw grain for processing germ-retaining rice.
Further, a whitening process of multiple grinding by a light machine and multiple white discharging by machines is adopted.
Further, selecting a carborundum roller rice mill with finer sand grain size for whitening; the rotation speed of the rice mill is not too high, and the rotation speed is changed from high to low according to different stages of whitening.
Further, when the roller length is 200mm, the rotating speed is 977r/min, and the clearance of the whitening chamber is 8mm, standard first-class germ-retaining rice can be obtained by 4 times of circulating whitening, and the germ retention rate is more than 80%.
The invention has the beneficial effects that:
the production of the germ-retaining rice meets the requirements of people on food nutrition and health care; in addition, the germ is reserved when the germ-remaining rice is processed, so that the rice yield is improved, the germ-remaining rate of the obtained germ-remaining rice is higher than 80%, and the nutrition in the rice germ can be well reserved, so that the germ-remaining rice has a wide market prospect, the health care consciousness of people is improved by strongly advocating and promoting the germ-remaining rice, and the nutritional structure of daily life is perfected.
Detailed Description
The present invention is further described below by way of specific examples, but the present invention is not limited to only the following examples. Variations, combinations, or substitutions of the invention, which are within the scope of the invention or the spirit, scope of the invention, will be apparent to those of skill in the art and are within the scope of the invention.
A processing method of germ-remaining rice, comprising the following steps: rough rice, cleaning, rice hulling, paddy separation, brown rice selection, brown rice tempering, multi-step whitening, polishing, germ rice grading, color selection, finished product warehousing, metering and packaging and finished product germ rice.
Selecting brown rice with embryo retention rate of above 90% as raw grain for processing embryo-retained rice.
The whitening process adopts a light machine to perform multi-grinding and multi-machine whitening.
Selecting a carborundum roller rice mill with finer sand grain size for whitening; the rotation speed of the rice mill is not too high, and the rotation speed is changed from high to low according to different stages of whitening.
When the roller length is 200mm, the rotating speed is 977r/min and the clearance of the whitening chamber is 8mm, standard first-class germ-retaining rice can be obtained by 4 times of circulating whitening, and the germ retention rate is more than 80%.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
