Abstract

The invention discloses a processing method for obtaining rice particles with smooth and full surfaces, which comprises the following steps: 1) soaking panus giganteus powder in a mixed aqueous solution of sodium dodecyl sulfate, trihydroxymethyl aminomethane and HCl, carrying out solid-liquid separation, collecting a solid phase, and washing and freeze-drying the solid phase; then respectively performing dissociation extraction by using formic acid and trifluoroacetic acid, and finally washing and drying by using absolute ethyl alcohol to obtain a solid A; (2) preparing a kiwi fruit water extracting solution to obtain a liquid phase B; 3) adding the solid A into unpolished rice after unhusked rice is husked, fully and uniformly stirring, then adding the liquid phase B into the unpolished rice according to the mass ratio of the liquid phase B to the unpolished rice being 5%-7%, then adding sophorolipid, fully and uniformly stirring, and introducing into a polishing machine for polishing; and drying the polished rice in a temperature range of 40-43 DEG C to obtain the rice particles with smooth and full surfaces. By optimizing the rice polishing process and introducing the polishing aid, the polished rice particles have smooth and full surface appearance and are crystal clear.

Description

technical field [0001] The invention belongs to the technical field of rice processing, in particular to a processing method for obtaining rice grains with smooth and plump surfaces. Background technique [0002] As the world's largest rice producer and consumer, my country's total rice output accounts for about 1 / 3 of the world's grain output. About 2 / 3 of the population in my country takes rice as the staple food, and rice plays an important role in my country's grain production. Citizens' consumption concept of edible rice is continuously upgrading, and it is no longer limited to eating enough to eat well in the traditional sense. According to market research, rice with good quality, lean appearance and clear appearance is more popular among people. Rice polishing is an important technology in the finishing of grain and oil products, and abrasion is inevitable. The main principle of polishing is to remove broken rice and Kang flakes after brown rice is rolled in multip...
