Description

A kind of method that utilization microwave pulse handles fast lifting eating quality of brown rice
Technical field
The invention belongs to grain intensive processing technical field, it is related to a kind of side of microwave fast lifting eating quality of brown rice Method, is specially a kind of brown rice improved using microwave pulse treatment technology, final acquisition edible quality, is the edible of brown rice Promote and its exploitation of functional food provides foundation.
Background technology
China is paddy production and consumption state the biggest in the world, and rice is our traditional staple food, its nutrition and food flavor product Matter is held the balance in meals.Traditional paddy processing method is Xian Longgu, removes the rice husk for accounting for paddy weight 1/5, obtains rough Rice.Brown rice is that paddy sloughs glume through hulling machine but still retains the grain of rice of this crust, aleurone and plumule.Brown rice is because retaining embryo Bud, rice bran layer, the natural bioactivity substance such as γ-aminobutyric acid lacked containing abundant nutrient and a variety of highed milled rice, Glutathione, γ-Hi-Z, ceramide etc., are proven to have anticancer, prevent and treat diabetes, hypercholesterolemia and obesity The effects such as, the prevention and treatment to health and modern civilization diseases are significant.Therefore, brown rice is recently by U.S. FDA Full cereal healthy food is classified as, proposal is directly eaten, it means that brown rice substitutes highed milled rice will turn into future health as staple food The new direction of meals.But, there is digestion time in impermeability and coarse-fibred presence due to brown rice surface chaff layer, brown rice Long, rice aroma is light, poor adherence, the shortcomings of mouthfeel and poor absorbability.Therefore, although its nutrient substance content is rich Richness, but do not turn into the staple food of the mankind always.
In order to improve brown rice cooking and eating quality, unpolished-rice nutrient material is made full use of, domestic and foreign scholars use various methods, Unremitting research is carried out, mainly including physics, chemistry and biological method:Physical method is mainly stone roller and cuts method, seasoning, radiation Method, ultrasonically treated, plasma treatment etc.;Chemical method mainly uses chemical reagent or water immersion etc.;Biological method is mainly Addition external source enzymatic reagent sprouts brown rice endogenous enzymes with certain method, and sprouted unpolished rice is made.Above-mentioned improvement brown rice quality Method also there are many shortcomings, such as easily cause nutrient loss, processing time is long, there is special chemical smell, treatment effeciency It is low etc..
At present, also there are some on the patented technology related to brown rice cooking quality, such as disclosed in CN103859282A A kind of method that ultrasound enzyme is combined fast lifting brown rice quality, is directed to being used in combination for physics and biological method, should Brown rice after method processing can reach the cooking quality of rice substantially, but this method processing time is long, and technique is cumbersome, and institute's reagent adding There is certain smell, influence brown rice quality;A kind of enzyme modified method of brown rice is disclosed in CN102423038A, the method is with brown rice For research object, brown rice peel layer is pre-processed by adding cellulase and carbohydrase, so that improve eating quality of brown rice, Pretreated brown rice and highed milled rice are under identical conditions of cooking and time, and mouthfeel is close to steamed rice.These methods or it is many or It is required for adding some chemical reagent or biological enzyme formulation less, method is relatively cumbersome, and the nutritional quality of brown rice can be produced Raw certain influence.
The content of the invention
Goal of the invention:For the deficiencies in the prior art, microwave pulse is utilized it is an object of the invention to provide one kind The method for handling fast lifting eating quality of brown rice.
Technical scheme:In order to realize foregoing invention purpose, the technical solution adopted by the present invention is:
A kind of method that utilization microwave pulse handles fast lifting eating quality of brown rice:Brown rice after japonica rice paddy rice huller paddy is entered Row screening and removing impurities, remove some and crack rice and miscellaneous rice;Brown rice is then put into microwave device pre-processed, will finally handled well Brown rice is put into baking oven and is further dried until reaching storage safe moisture.
The method that described utilization microwave pulse handles fast lifting eating quality of brown rice, is comprised the following steps that:
1) rice huller paddy is carried out again after japonica rice paddy being carried out into screening and removing impurities;
2) brown rice that Jiang Longgu is obtained carries out primary dcreening operation, removes and cracks rice and miscellaneous rice;
3) take brown rice packing obtained by step (2) to be put into polyethylene plastic packaging bag, be placed in microwave device and enter horizontal pulse processing, place Reason time 60-120s, pulse working time 10-20s, interval time 10s-30s;
4) by step 3) obtained by brown rice be put into 30 DEG C of -40 DEG C of heated-air drying 60-90min in baking oven, make brown rice moisture Content is reached below stored grain safety;
5) by step 4) gained brown rice packed, gained is the brown rice after microwave modification.
The microwave frequency of the microwave device is 2450MHz, is made up of eight microwave generators, general power 0-8000W can Adjust.
The microwave power is 1500-2500W.
The method that described utilization microwave pulse handles fast lifting eating quality of brown rice, before microwave treatment, is adjusted rough Rice moisture is 13-16%.
The method that described utilization microwave pulse handles fast lifting eating quality of brown rice, is slowly added by atomizing type Moisture is until brown rice moisture content is 15%.
Beneficial effect:The skill existed for brown rice poor quality, the characteristic of poor taste and existing brown rice quality improving method Art bottleneck, the present invention creatively provides a kind of microwave pulse handling process, only pure physical treatment method, in special process bar Under part, without germination process, you can cooking and eating quality (such as moisture content, hardness, elasticity, cohesion, the friendship of fast lifting brown rice Connection property and restorative etc.), and brown rice after microwave treatment more fully retains the nutriment and functional components in cortex, presses After highed milled rice boiling method is cooked, mouthfeel is similar with steamed rice.Traditional chemistry, biological means are replaced with pure physical means, plus Short between man-hour, operation is simple, suitable industrialized production, is that the popularization of brown rice edible is had laid a good foundation.After processing Brown rice superficial cortical layers there is crackle, but constantly grain.The method has the advantages that production efficiency height, cost are low, pollution-free, simultaneously Product has the advantages that small nutritive loss, easy cooking, digested well.
