Description
Technical field
The present invention relates to a kind of can the production method of brown rice of longer-term storage, belong to field of deep processing of farm products.
Background technology
China is paddy production and consumption state the biggest in the world, and rice is our traditional staple food, with a very important position in meals of its nutrition and Cooking Quality.Tradition paddy processing method is Xian Longgu, removes the rice husk accounting for paddy weight 1/5, obtains brown rice.Brown rice is that paddy is sloughed clever shell through hulling machine but still retains the grain of rice of this crust, aleurone and plumule.And the normal polished rice used eliminates crust, aleurone and the plumule in brown rice in our daily life, but the vitamin of cereal and inorganic salts are mainly distributed among paddy embryo and Mai Pi, only remain a large amount of protein.
Brown rice is protected because not having clever shell, is rich in outside nutrition pericarp and interior tissue be directly exposed to; Simultaneously brown rice has complete embryo, breathes vigorous, as stored manner is not suitable for, very easily infestedly to go mouldy, and quality declines rapidly b1.And due to brown rice lipid content high, easily cause water-disintegrable and oxidisability to become sour, cause the deterioration of brown rice quality, and occur that old rice is smelly.So brown rice storage problem also improves with people's living standard and seems more and more important.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of can the production method of brown rice of longer-term storage.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of can the production method of brown rice of longer-term storage, the technological process of production is as follows:
1) screening processes raw material;
During selection meets " GB1891-1999 high quality paddy ", the brown rice of one-level paddy processing is as raw material; Described paddy is carried out rice huller paddy and obtains brown rice; Content of mineral substances≤0.02 of described brown rice, contaminating black rate is 0, and the brown rice that embryo is intact at least accounts for 98% of total amount; Described paddy is indica type non-glutinous rice;
2) screening and removing impurities;
Screen out magnetic metal thing, porcelain fragment, sheet glass, worm excrement, mouse excrement, worm and worm corpse;
3) washing and sterilizing;
Brown rice is placed in germination tank, first inwardly passes into cold water steam, make described germination tank humidity reach more than 60%, then after passing into ozone closed sterilizing 10 ~ 20min;
4) water suction is soaked;
Water brown rice after washing and sterilizing being put into 20 DEG C ~ 30 DEG C soaks, and changes water once every 12h, 1 ~ 2 time repeatedly;
5) germination activation;
Brown rice water after soaking clean and drains away the water, the brown rice after draining to be distributed in porcelain dish and to cover gauze, afterwards by described porcelain dish as in insulating box, control germination temperature 25 DEG C ~ 30 DEG C;
When the bud of brown rice reaches 0.5mm ~ 1mm, terminate activation of germinateing;
6) dry process;
The brown rice of the activation that terminates in step 5) to germinate is proceeded to microwave drying oven rapidly carry out processing and make the moisture of brown rice be less than 15%; The biologically active that this step reduces brown rice simultaneously reduces, and completing can the production method of brown rice of longer-term storage.
The improvement of technique scheme is: after selecting results as the indica type non-glutinous rice of raw material in step 1), natural drying is to standard moisture, and germination percentage is high, germinating energy strong, without insect pest, disease-free, without the plague of rats, do not generate heat the paddy gone mouldy; Described germination percentage >=95%, described germinating energy >=90%.
The invention has the beneficial effects as follows: utilize the humidity in cold water steam raising germination tank, to improve the utilization rate of ozone in sterilization functions, and utilize microwave drying while completing dry process, the biologically active reducing brown rice makes the enzymatic activity in brown rice reduce the plumule undue growth avoiding brown rice, utilize microwave drying to carry out sterilization processing, killing three birds with one stone is enhanced productivity simultaneously.
