[0004] Therefore, coix seed widely appears on the human dining table and gradually becomes a necessity of people's life. However, barley can only be harvested once a year, and barley itself is rich in oil. During storage, the oil is easily oxidized, resulting in rancidity and a nasty smell. Seriously affect the quality of barley, and it is easy to deteriorate and spoil during long-term storage

Embodiment 1
[0029] This embodiment provides a processing method for prolonging the storage period of coix seed rice, the specific process is as follows:
[0030] a. Selection and classification: take the barley rice to be processed, remove unfulfilled and rotten particles, and color sort and classify;
[0031] b. Electrolytic cleaning: Soak the above-mentioned spare barley in clean water, control the temperature of the clean water to 50°C, keep the temperature constant, and keep stirring, insert the negative and positive two-stage inert electrodes, electrolyze for 25 minutes, and the current size is 15A; Oxygen provides sufficient oxygen for the oxidation of easily oxidizable substances in barley, and effectively promotes the oxidation of easily oxidizable substances under the action of stirring and electrolysis;
[0032] After the electrolysis, add river sand accounting for 1 / 3 of the total weight of barley, wash at a stirring speed of 3200r / min for 12 minutes, remove part of the oxidize...
Embodiment 2
[0040] This embodiment provides a processing method for prolonging the storage period of coix seed rice, the specific process is as follows:
[0041] a. Selection and classification: take the barley rice to be processed, remove unfulfilled and rotten particles, and color sort and classify;
[0042] b. Electrolytic cleaning: Soak the above-mentioned spare barley in clean water, control the temperature of the clean water to 45°C, and keep stirring at a constant temperature, insert the negative and positive two-stage inert electrodes, electrolyze for 35 minutes, and the current size is 8A; Oxygen provides sufficient oxygen for the oxidation of easily oxidizable substances in barley, and effectively promotes the oxidation of easily oxidizable substances under the action of stirring and electrolysis;
[0043] After the electrolysis, add river sand accounting for 1 / 3 of the total weight of barley, wash at a stirring speed of 3500r / min for 10 minutes, remove part of the oxidized oxid...

Abstract
The invention relates to the technical field of grain processing, in particular to a processing method for prolonging shelf life of barley rice. The method comprises the steps of selection and classification, electrolytic cleaning, acidolysis for impurity removal, mixing and cleaning, freeze-drying, ozone sterilization, package and other processing procedures. The processing method for prolongingthe shelf life of the barley rice has the advantages that beta-cyclodextrine is added to wrap the barley rice, so that long-term stability of volatile matter in the barley rice is kept; a layer of protective film is formed on the surface of the barley rice under the cooperative action of an HA compound antioxidant, which has a good protective function on the color, fragrance and the like of the barley rice, and isolates residual readily oxidizable substances in the barley rice from oxygen, thereby insulating oxidation, and prolonging the shelf life of the barley rice; finally, freezing and freeze-drying technologies are combined to remove water in the barley rice and reserve the main components and value of the barley rice, thereby effectively prolonging the shelf life of the barley rice.
Description
technical field [0001] The invention relates to the technical field of grain processing, in particular to a processing method for prolonging the storage period of coix seed rice. Background technique [0002] Coix seed, also known as coix seed, coix seed, and six millet seeds, is the seed of coix seed, a grass plant in the family Gramineae. Cool in nature, sweet in taste, light in taste, enters the spleen, lung, and kidney meridians, has the effects of diuresis, invigorating the spleen, removing numbness, clearing away heat and evacuating pus. Barley is grown in warm and humid Shibiandi and valleys and streams, and it is more common below 2000 meters above sea level. [0003] Because of its high nutritional value, barley is known as "the king of grasses in the world"; in Europe, it is called "the grain of life and health"; in Japan, it has recently been listed as an anti-cancer food, so its value has doubled. The seed of Job's tears is easy to digest and absorb, whether it...
