Description

Enriched rice or barley and production thereof

Relevant enriched rice or barley and the production thereof that contains the nutrient of appropriate balance of the present invention.

Grain such as rice and barley are through purified treatment, just sell after the refining profile, and before boiling, generally all want earlier through washing.Just at refining or water-washing process, a large amount of basic nutrition element such as vitamin and mineral matters have been lost.

In order to overcome this shortcoming, the interpolation Cobastab has been arranged ₁Enriched rice or barley and with the rice mixed selling, this contributes to some extent to improving nutritional status.But, during balance on considering nutrition, obviously the more important thing is to provide not only have Cobastab ₁, but also to have the rice or the barley of other nutrient of appropriate balance.

The method of typical production enriched rice or barley, rice (Acid Parboiled rice) method is boiled in the so-called similar acid that has, and cladding process.Previous method comprises rice or barley raw material are immersed in the acidic aqueous solution that adds nutrient spends the regular hour, then in the extremely short time in superheated steam cooking rice or barley, dry grain in thermal air current at last.But, use this method, rice or barley can not add water insoluble, and liposoluble vitamin is such as vitamin A, vitamin D and vitamin E.Calcium, iron and mineral matter can not be used for this purpose, and this is owing to donors or fertile material are insoluble or only are slightly soluble in water accordingly in a large number.

For cladding process, a lot of specialist papers are arranged, the main process of the method for being recommended comprises, covers rice or barley with the nutrient that adds.While has been lost these nutrients when washing these cereal ante cibum in order to prevent to do, will be water insoluble with some, solution that can film forming material, cover these cereal again, for example using zeins, is the protein component of a kind of India corn, or the shellac natural resin of secreting out with certain insect body surface, be dissolved in ethanol, in isopropyl alcohol or the suchlike solvent.The method that has can be produced reinforced refining rice or the barley that contains liposoluble vitamin and mineral matter, but use solvent, this just not only will strengthen the size of crucial production equipment, and will improve the cost of reinforced refining rice or barley in a large number.

In order to overcome top shortcoming, the method for having invented has on rice or barley corn, fusion or deposition nutrient, further use oil (fat) and (or) wax is included on the covered grain, wraps starch at last again.This method helps enrichment grain, and final products have when washing rice as ante cibum the superiority of unlikely loss nutrient.But, when cereal is made with extra care in sale, generally to be added to these reinforced cereal in the proper ratio in the common rice and go, in this mixed process, the starch cover layer of above-mentioned reinforced cereal just is worn away, expose oil (fat) and (or) the wax layer, in the case, flow freely, the result who grinds has played bad effect mutually, cause mixing inhomogeneous, or oil (wax) to be bonded on the mixer, on the feeder or on the other parts of equipment.Moreover when washing the mixture of these rice and enriched rice or barley with water, the latter's stratum granulosum loses gradually, exposes oil (wax) layer, so cereal causes cereal to be swum to the affinity decline of water, loses along with washing.So when washing such product, want SC.

In view of above-mentioned technical situation, people of the present invention have done further research, find that all above-mentioned shortcomings can avoid, method be with oil (fat) or (with) wax covers rice or barley corn, cover on the grain of as above handling with a kind of hydrophilic emulsion, last is that basic coverture covers on it in order to starch again.Immediately following the further research of this discovery, the result has developed the present invention.

So, purpose of the present invention is exactly that a kind of refining enriched rice or barley of having improved quality will be provided.

Another object of the present invention just provides a method of producing refining enriched rice or barley, comprise nutrient blending deposit in rice or the barley grain or above, with not melting at normal temperatures but heat time fusing oil (fat) or (with) wax covers on every kind of cereal, cover on it with hydrophilic emulsion, further cover on it again with the starch base coverture." oil (fat) " this meaning be " oil or (with) fat ", mainly comprise the material of fatty glyceride one class.

According to the present invention, can be used for reinforced as previously mentioned rice or the barley raw material of handling, be hard-core fully.For example, the kind of these raw material cereal, refining degree or the like all is random.As for refining barley or like that, be meant with general pressure of pressing the rolling method to obtain and roll over barley.

According to the present invention, be used for to the reinforced nutrient of rice or barley comprising, water-soluble vitamin (Cobastab ₁, Cobastab ₂, vitamin C, Cobastab ₆, nicotinic acid, pantothenic acid etc.), be dissolved in the vitamin (vitamin A, vitamin D, vitamin E etc.) of fat, amino acid (lysine, threonine etc.) or (with) mineral matter (calcium, iron etc.).Each of these nutrients can be selected from all cpds, from natural prodcuts, extracts, and the purifying preparation, these nutrients have gone through to be added in the grain to go.

According to the present invention, used oil (fat) or (with) wax, can be any fully, melt when heat as long as it does not melt at normal temperatures.Usually, preferably oil (fat) or (with) fusing point of wax is about 40 ℃ to 80 ℃.

For example, above-mentioned oil comprises hydrogenated vegetable oil, resembles hydrogenation soya-bean oil, cotton seed oil, rapeseed oil, rice bran oil, corn wet goods, animal tallow such as butter, lard etc., and the hydrogenation animal tallow that obtains from them.Wax comprises animal or plant wax, for example rice bran wax, Brazil wax, cane sugar wax, beeswax, spermaceti etc.

According to the present invention, used hydrophilic emulsion can be any sucrose fatty ester, sorbitan fatty acid esters and fatty acid glyceride, the HLB value of these esters (hydrophilic-hydrophobic balance value) is 8 or bigger, preferably 10 or bigger, protein (for example soybean protein, gelatin, casein sodium etc.) or plant gum (for example, Arabic gum, bassora gum etc.).

According to the present invention, used starch for example can be, cornstarch, potato starch, wheaten starch and rice starch and grain flour, for example wheat flour and rice meal.These all are the original state materials of usefulness.Preferably the particle diameter of wheaten starch is not more than 10 μ, and such cover layer can be more fine and close, and can resist mechanical shock.

This method is used as typical raw material to rice as benchmark, equally also uses refining barley.

Nutrient blending or be deposited in the rice particle or top method, be exactly general method.When nutrient is water miscible, rice at first is immersed in the acid solution of nutrient by giving the fixed time, in very short time, use the superheated vapour boiling then, dry in the air stream of heat at last.Perhaps, whitened rice grains also can usually cover with these nutrition.But in general, still preceding a kind of method can obtain preferable quality, because rice seed lac materialization.If nutrient is water-fast or can only be water-soluble on a small quantity, for example liposoluble vitamin, mineral matters etc. then or whitened rice grains or above-mentioned deposited the big grain of rice that water soluble nutrient and drying are crossed, all deposit with cladding process.

Above-mentioned covering method can be with general way.Exactly rice is put in the groove of a covering usefulness, advances in the thermal air current at drum, the aqueous solution that contains interpolation nutrient and binding agent is sprayed to rice get on, binding agent is a sucrose for example, gelatin, alphalise starch or (with) like that.

Adding the kind and the ratio of nutrient can optionally select.For example practice preferably is that the nutrient that adds is exactly at the nutrient of loss when refining that shells, recover damage like this, and the level when returning to without refining or yellow rice.The amount of nutrient generally depends on the ratio of reinforced cereal to the common cereal (refining cereal) of blending.For example, when the ratio of the reinforced common cereal of cereal blending be 1: 100 to 200 the time, fusion or deposit in the refining cereal or top nutrient amount as follows:

Cobastab ₁: about 0.07 gram is to 0.3 gram

Cobastab ₂: about 0.003 gram is to 0.012 gram

Nicotinic acid: about 0.3 gram is to 1.2 grams

Pantothenic acid: about 0.1 gram is to 0.5 gram

Cobastab ₆: about 0.004 gram is to 0.02 gram

Vitamin E: about 0.07 gram is to 0.3 gram

Vitamin A: about 50000(international unit) extremely

The 200000(international unit)

Vitamin D: about 20(international unit) to the 100(international unit)

Vitamin C: about 1 gram is to 5 grams

Calcium: about 0.4 gram is to 1.6 grams

Iron: about 0.06 gram is to 0.25 gram

Lysine: about 3 grams are to 15 grams

(the reinforced cereal that top quantity processes based on 100 grams).

Consider and strengthen the required standard volume of grain that when bigger than top amount, then reinforced cereal and common cereal are difficult to blending evenly.On the other hand, less amount is also also bad, because this will improve the ratio of reinforced cereal and common cereal in a large number.

In rice or above the rice after blending or the deposition nutrient, cereal cover again with oil (fat) or (with) do not melt at normal temperatures but the wax that melts when heat.The method that the typical case covers comprise the oil (fat) that has melted or (with) wax, or with oil emulsion (fat) or (with) emulsion that wax prepares, on the big grain of rice, spray.The emulsion that uses is such as sucrose fatty ester, fatty acid glyceride or dehydration sorbitol fatty acid ester, or a kind of natural glue, and such as lecithin, Arabic gum, xanthic acid (Xanthane) glue, gelatin or agar.

Ordinary circumstance, the emulsion covering method has bigger superiority aspect operating efficiency.Because it can carry out at normal temperatures, and can guarantee that oil/fat more effectively is deposited on the big grain of rice.Prepare this kind emulsion, approximately want 100 to 1000 weight parts waters, and about 1 to 100 weight portion emulsifying agent be added to per 100 weight portions oil (fat) or (with) in the wax, mixture is then used common method emulsification.Spraying covers and can spray on the big grain of rice with above-mentioned emulsion, is covering in the groove about 20 to 70 ℃ greatly, stirs the hot-air that constant speed supply simultaneously is 40 to 100 ℃ with constant speed.

In order to prevent to wash rice time loss nutrient, generally preferably adopt cladding process, make rice after the processing have at least 2 heavy % oil (fat) or (with) wax, preferably about 3 heavy %, if covered blocked up oil (fat) and wax on the big grain of rice, the fragrance and the viscosity of boiling rice all will degenerate.For preventing above-mentioned situation, the content on the rice after general hope guarantees to process is no more than 7 heavy %.

If the big grain of rice that is loaded with nutrient cover oil/fat or (with) before the wax, cover starch earlier, then oil/fat or (with) wax can deposit very evenly and tight, so can obtain the more gratifying product of high-quality.In the case, use the ratio of starch to be, the rice of processing will contain the starch of the heavy % of 2-7 that has an appointment.

Generally preferably before continue covering above-mentioned hydrophilic emulsifying agent, rice cover earlier with above-mentioned oil (fat) or (with) wax, make surface smoothing, through so handling, then in water-washing step, can reduce the loss of nutrient.This kind processing procedure is a heating grain to oil (fat) or (with) softening temperature of wax, in the rotary machine container, rotatory force is applied to grain simultaneously and gets on to guarantee being in contact with one another of grain.

The cereal of so handling, thereafter again oil (fat) or (with) cover on the wax with hydrophilic emulsion, the soverlay technique preferably of standard is with the aqueous solution of the hydrophilic emulsion that contains about 2 to 20 heavy % or the suspension of water, according to a conventional method, spraying covers on the big grain of rice.

Temperature to big grain of rice overwrite procedure is enough low, with the oil (fat) that prevents to deposit or (with) fusing of wax, the covering of general hydrophilic emulsion the most preferably is approximately the heavy % of 0.05-1 of processing back product.The method that another one covers the big grain of rice with above-mentioned hydrophilic emulsion comprise the moistening oil of first water (fat) or (with) cover layer of wax, spray hydrophilic emulsion then from the teeth outwards with powdery.

Then, on hydrophilic emulsion layer, further cover again to contain starch base coverture greater than 50% starch.Be conveniently, this process can be used general overlay device, for example can spray the water slurry that contains starch and a kind of adhesive on the big grain of rice, or spray starch on the grain that sprayed adhesive.Above-mentioned adhesive can be selected from one or more glue, such as gelatin, and Arabic gum, locust bean gum, mosanom etc., carbohydrate such as sucrose etc., alphalise starch, dextrin etc.

Cover in the starch step, the temperature of grain is enough low, prevent the oil (fat) that deposited and (or) the wax fusing, the overlay capacity of starch, preferably approximately quite the 2-25 of converted products weighs %.Above-mentioned adhesive consumption preferably approximately is the heavy % of the 0.2-45 of amount of starch.

According to the present invention, top method can obtain reinforced refining rice.Usually, rice is also further painted, to make it more attractive.Coloring process can add Cobastab ₂Or like that (for example, the peaceful look of chlorophyll, carotene, mast) colouring agent goes to the starch base coverture, or sprays the aqueous solution of these colouring agents to the starch cover layer.

According to the present invention, reinforced refining rice or barley product because the step useful oil of producing (fat) or (with) wax covers refining grain, cover again with hydrophilic emulsion.Further cover again, so superior, functional with the starch base coverture.

And in the methods of the invention, because stratum granulosum is deposited on the hydrophilic emulsion layer, stratum granulosum is firmly on rice or barley corn, so starch in mixing and transport the impact that these products take place, or during washing, is not easy to peel off.Therefore, enriched rice is in mixing and transportation, and the flow behavior that has is identical with those rice, so easy blending.Also have, when washing this product with water,, can not take place that grain swims and along with washing brings trouble in the loss because grain has affinity preferably to water.So the loss of nutrient also is minimum in the water-washing process.

In addition, old technology in the past such as corn gum, shellac is the same with using, and this method does not comprise with an organic solvent in covering step.So production equipment is not quite also uncomplicated, also reduced production cost.And according to method of the present invention, enriched rice or barley are painted easy and firm, so being improved in appearance at treating grain.
