Description

Staple grain and brown rice nutritional rice and preparation method thereof
Technical Field
The invention relates to the technical field of food, in particular to staple grain brown rice nutritional rice and a preparation method thereof, and the staple grain brown rice nutritional rice.
Background
The brown rice is recognized as whole-grain nutritional rice, and is considered to be a popular healthy staple food in terms of natural nutritional composition, the brown rice is particularly suitable for people with high blood pressure, high blood sugar and pregnant and lying-in women, and the brown rice is the best source of dietary fiber; however, the taste and the mouthfeel of the cooked brown rice or the cooked porridge are difficult to be accepted by the public, namely the brown rice has rough mouthfeel, is hard and astringent, is difficult to swallow and has unpleasant smell.
The reason why the cooked rice or porridge made of brown rice has a bad taste is that the brown rice has a high content of coarse fibers and a high content of horny layer cells in the pericarp, the seed coat and the aleurone layer and has a compact texture, and the coarse fibers and the horny layer cannot be softened to a palatable degree by only heating and water during cooking, the water cannot easily enter the endosperm, and the starch in the endosperm cannot be easily gelatinized, so that the cooked rice or brown rice porridge has a poor palatability. In addition, since the brown rice husk layer contains a large amount of substances such as coarse cellulose and horny layer, when the rice or porridge is cooked by heating, steam having an unpleasant odor is generated.
The brown rice or the germinated brown rice does not exist in the market, the bottleneck of poor taste value is broken through, the brown rice or the germinated brown rice is accepted by wide consumers as daily staple food, the rice is an absolutely dominant staple food product in rice products at present, the rice is finely processed, the pericarp, the seed coat, the aleurone layer and the embryo bud are removed, and the rice is repeatedly ground and polished, so that the original nutrition of the rice is greatly lost, and the fine grinding processing facilities and equipment, manpower and electric power are greatly consumed.
At present, thousands of brands of brown rice (such as a Qiaofu Dazhong brand) and a plurality of brands of glutinous brown rice (such as a Wuchangtai brand) sold in China and germinated brown rice (such as a Qinkang brand) are sold in China, and the smell generated in the cooking process and the taste and the mouthfeel of cooked rice or porridge are not good in both brown rice and germinated brown rice, so that the brown rice is unacceptable for the general consumer. In 2018/2019 years, the rice in China is used for staple food consumption of 1.585 million tons, the rice hulls account for 20 percent of the weight of the rice, and the rice yield of processed rice is about 65 percent. Based on the calculation, by adopting the technical scheme of the invention, if the rice is completely consumed and changed into brown rice, 2378 ten thousand tons of paddy rice can be saved every year, 1.76 million people can eat grain all the year round, and 4754 thousand mu of cultivated land can be saved every year. By 2018, diabetics in our country have 1.16 million people, overweight and obese people have 2 million people, 0.15 million pregnant and lying-in women are newly added in 2018, brown rice is used as staple food instead of rice, and particularly, glutinous brown rice is used as daily staple food instead of rice, so that health value brought to the nation is immeasurable.
The prior art discloses a method for improving the taste of a plurality of brown rice, wherein CN 106562214A is a method for preparing germinated brown rice, and the invention discloses a method for preparing germinated brown rice, which comprises the following steps: (1) sterilizing the brown rice; (2) cleaning the sterilized brown rice, and then soaking the brown rice in water at the temperature of 22-28 ℃ for 3-5 hours; (3) germinating the soaked brown rice for 48-72 h at 26-30 ℃ and with relative humidity of more than 95%; (4) drying the germinated brown rice to obtain germinated brown rice. According to the preparation method of the germinated brown rice, the brown rice is sterilized, soaked and germinated, and finally dried to prepare the germinated brown rice. The main defects of the preparation method are that the smell generated in the process of steaming the germinated brown rice of the product is almost the same as the taste and the mouthfeel of cooked rice or porridge and the brown rice, and the preparation process needs additional processing facilities and equipment, manpower and electric power input and has high cost. The brown rice needs to be soaked in sodium hypochlorite serving as a chemical bactericide in the preparation process, so that potential food safety hazards exist; the color of the product is unpleasant. In general, the mass consumer is still unacceptable. CN106983081A provides a preparation method of germinated brown rice and a method for preparing instant rice by using the germinated brown rice. The preparation method comprises the steps of pretreating the brown rice, soaking the brown rice in citric acid/sodium citrate buffer solution for a short time, germinating for 18-20 hours at 28-33 ℃, draining and the like, so that the generation of peculiar smell is reduced by germination at a shallow degree, the elutriation frequency is reduced, and the loss of nutrient components and gamma-aminobutyric acid is reduced. And secondly, providing a method for preparing the instant rice by the germinated brown rice through ultrahigh pressure modification treatment, wherein the method comprises the steps of solving the problems of poor palatability, peculiar smell and retrogradation of the germinated brown rice through the ultrahigh pressure modification treatment, and curing and ensuring commercial sterility of the product through temperature cooking. The method has the advantages of simple process, short germination period, no drying process, energy conservation and consumption reduction, and the prepared germinated brown rice has strong fragrance, no peculiar smell, good palatability, high nutrient content, normal-temperature storage and no retrogradation, and is suitable for industrial production; the prepared instant rice is high in cost and not suitable for being consumed as staple food by mass families, the prepared instant rice is soaked in a sodium citrate solution and germinates for 18-20 hours at 28-33 ℃ in the preparation process, the loss of nutrient components of germs is easily caused, and the high-pressure modification treatment destroys the nutrition of active substances such as original vitamins of the rice; the preparation process needs more processing facilities, equipment, manpower and electric power investment, and the cost is huge. CN103719703A discloses an enzyme hydrolysis method for softening the skin layer of brown rice under the action of ultrasound by using cellulase and pectinase complex enzyme to improve and reduce the hardness of germinated brown rice, which is shown in (Zengdan, plum-polygala root, Chenyouqing and the like; the influence of the enzyme hydrolysis process on the improvement of the taste of germinated brown rice [ J ]. food and machinery, 2011 (2011) (71-74.). The main defect of the preparation method is that under the action of enzyme, the cellulose of the bran layer of the brown rice is damaged, so that a large amount of nutrient substances stored in embryo buds are lost, more importantly, the substances such as crude fibers in the seed coat, the grain coat and the aleurone layer of the brown rice cannot absorb water to soften and penetrate into the embryo milk of the brown rice in an accelerating way, and the problem of low taste value of the brown rice still cannot be solved; the preparation process requires additional processing facilities and equipment, labor and power input, and is high in cost.
Therefore, it is necessary to provide a method for retaining whole grain nutrition staple food which can be quickly consumed by the general public in daily consumption, and the generated smell and the taste of cooked porridge or rice are both good through the daily cooking process.

It is expressly intended that all such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the scope of the invention. While the methods and applications of this invention have been described in terms of preferred embodiments, it will be apparent to those of ordinary skill in the art that variations and modifications in the methods and applications described herein, as well as other suitable variations and combinations, may be made to implement and use the techniques of this invention without departing from the spirit and scope of the invention.
The invention provides staple grain brown rice nutritional rice, which comprises the following components in part by weight:
5-50 parts of brown rice;
50-95 parts by weight of glutinous brown rice;
0.2-3.5 parts by weight of soybean lecithin, lecithin and/or vegetable oil.
The invention provides staple grain brown rice nutritional rice which comprises the following components: 5-50 parts of brown rice; preferably, the brown rice comprises 17-45 parts by weight of brown rice; more preferably 20 to 42 parts by weight; most preferably 28 to 38 parts by weight.
The brown rice is non-glutinous brown rice, and specifically can be colorless brown rice or colored brown rice; wherein the colored brown rice is selected from black brown rice or red brown rice.
The brown rice is not limited in source, is available in the market, and can be north pure non-glutinous brown rice.
The brown rice, non-glutinous paddy rice, kernel with intact pericarp, seed coat, aleurone layer and germ, executes GB/T18810 brown rice standard, the brown rice is classified as follows: early indica brown rice, late indica brown rice, and japonica brown rice (non-glutinous rice); indica glutinous brown rice and japonica glutinous brown rice.
Brown rice is nominally called brown rice in japan, and the brown rice and brown rice referred to in this patent are the same. Compared with rice (GB/T1354), the brown rice is rich in vitamins, minerals and dietary fibers.
Compared with rice, the brown rice contains 12 times of vitamin B1, 10 times of vitamin E, 14 times of dietary fiber, 1.7 times of calcium, 2.75 times of iron, and 3.2 times of nicotine. The vitamin B and the vitamin E of the rice bran and the germ part in the brown rice can improve the immunologic function of a human body, promote blood circulation, help people eliminate depressed and irritable moods and enable people to be full of vitality. In addition, the brown rice contains potassium, magnesium, zinc, ferrum, manganese and other trace elements, and is beneficial to preventing cardiovascular diseases and anemia. It also retains a large amount of dietary fiber, and has effects in promoting proliferation of intestinal beneficial bacteria, accelerating intestinal peristalsis, softening feces, and preventing constipation and intestinal cancer; the dietary fiber can be combined with cholesterol in bile to promote the discharge of cholesterol, thereby helping patients with hyperlipidemia to reduce blood lipid. Brown rice is particularly beneficial for diabetic patients and obese people. Because the carbohydrate in the blood sugar is wrapped by the coarse fiber tissue, the digestion and absorption speed of the human body is slow, and the blood sugar can be well controlled; meanwhile, the microelements such as zinc, chromium, manganese, vanadium and the like in the brown rice are beneficial to improving the sensitivity of insulin, and are very helpful for people with impaired glucose tolerance. Japanese studies have demonstrated that brown rice has a much lower glycemic index than fine-milled rice, has better satiety when eaten in the same quantity, and is beneficial to controlling food consumption, thereby helping obese people lose weight. However, because the brown rice pericarp and the seed coat have more dense substances such as crude fiber, stratum corneum cell and the like, the cooked rice or porridge has rough mouthfeel and is hard and astringent and difficult to swallow; the smell is also unpleasant during the cooking process.
The invention provides staple grain brown rice nutritional rice which comprises the following components: 50-95 parts by weight of glutinous brown rice; preferably 55 to 83 parts by weight; more preferably 58 to 80 parts by weight; most preferably 62 to 72 parts by weight.
The glutinous brown rice can be colorless glutinous brown rice or colored glutinous brown rice; wherein the colored waxy brown rice is waxy purple brown rice.
The source of the glutinous brown rice is not limited, the glutinous brown rice is commercially available, and the glutinous brown rice can be north pure glutinous brown rice.
Glutinous rice is a sticky variant of rice, and is mainly different from other rice in that starch in the endosperm of glutinous rice is mainly amylopectin, and accounts for about 98 percent. The glutinous brown rice is the kernel with the husk, the seed coat, the aleurone layer and the germ of the glutinous rice removed, and the GB/T18810 brown rice standard is implemented. It is used for steaming rice and cooking porridge, and has sticky and glutinous taste and unpleasant smell generated during steaming process. The nutrient components are basically equal to the non-glutinous brown rice. However, compared with non-glutinous brown rice, glutinous rice has a very good health care function, and modern researches also prove that: the glutinous rice is rich in B vitamins, and has effects of warming spleen and stomach, invigorating middle warmer and invigorating qi. Has certain relieving effect on deficiency-cold of spleen and stomach, poor appetite, abdominal distention and diarrhea; glutinous rice has astringent effect, and also has good dietetic therapy effect on frequent micturition and spontaneous perspiration; the glutinous brown rice is warm in nature and is an important nourishing food. The efficacy of glutinous rice is summarized as the main indications in Ben Cao gang mu: stomach cold pain, diabetes, frequent micturition, spleen and stomach qi deficiency, diarrhea, spontaneous perspiration due to qi deficiency, pregnant waist and abdomen distention, short breath after labor, asthenia, and asthenia. In China, the glutinous rice variety only accounts for 3.59 percent of all the rice varieties, and the yield is not matched with the consumption demand. The glutinous brown rice is rich in nutrition, contains more than 20 vitamins and minerals, and 23 amino acids, and is helpful for in vivo energy metabolism, skin and mucosa health maintenance, dark vision maintenance, and antioxidation. The series of foods and drinks developed by using glutinous rice are more than hundreds of types, and most of the foods and drinks are traditional snacks, glutinous rice porridge, rice cakes, rice dumplings, glutinous rice balls and the like. The rice food prepared by using the sticky rice as the main raw material does not reach balanced matching and standardized production. Therefore, the staple grain brown rice nutritional rice prepared by using the waxy brown rice and the brown rice as main raw materials and using the soybean lecithin, the lecithin or the vegetable oil as auxiliary materials can meet the requirements of most consumers in terms of taste, smell and nutritional value.
The glutinous brown rice and the non-glutinous brown rice are mixed according to a certain proportion. The waxy brown rice contains almost all amylopectin, is sticky compared with non-waxy brown rice, can improve the softness of rice or porridge, but has too soft and waxy mouthfeel when being used for steaming rice alone; the non-glutinous brown rice mainly contains amylose, and has coarse and hard mouthfeel. Therefore, the technology adopts the glutinous brown rice and the non-glutinous brown rice to be mixed according to a certain proportion and is used for steaming rice or cooking porridge, so that the requirement of the public bottom line on the taste can be met.
The non-glutinous brown rice rich in amylose and the glutinous brown rice rich in amylopectin are creatively mixed according to a specific proportion, and the two kinds of brown rice make up for each other to ensure that the mouthfeel of the cooked rice or the porridge is proper.
The staple grain brown rice nutritional rice provided by the invention comprises 0.2-3.5 parts by weight of soybean lecithin, lecithin and/or vegetable oil, wherein the vegetable oil is one or more of rapeseed oil, peanut oil, hemp oil, corn oil, rice oil, camellia oil, palm oil, sunflower oil, soybean oil, linseed oil, grape seed oil, walnut oil, peony seed oil, blend oil, canola oil and perilla seed oil; preferably 0.5 to 3.0 parts by weight; more preferably 0.8 to 2.5 parts by weight; most preferably 1 to 2 parts by weight.
Wherein the soybean lecithin can be one of soybean lecithin, lecithin or vegetable oil, and can also be two or more of soybean lecithin, lecithin or vegetable oil;
specifically, the soybean lecithin and vegetable oil can be combined; it may also be a combination of lecithin and vegetable oil; it can also be a combination of soybean phospholipids, lecithin and vegetable oil.
Wherein the preferable proportion is 0.1-1.7 parts by weight of soybean phospholipid or lecithin; more preferably, the proportion is 0.1-1.2 parts by weight of soybean lecithin or lecithin; the most preferred proportion is 0.1-1.0 weight part of soybean phospholipid or lecithin
Soybean lecithin is an essence extracted from soybean, is an ester composed of glycerol, fatty acid, choline or cholestyramine, and is soluble in oil and nonpolar solvent. Soy phospholipids are complex in composition and contain mostly lecithin (about 34.2%), cephalins (about 19.7%), inositol phospholipids (about 16.0%), phosphatidylserine (about 15.8%), phosphatidic acid (about 3.6%) and other phospholipids (about 10.7%). Contains a large amount of lipid components required by human body, and is mainly used as an emulsifier, a humectant, a thickener and the like in the food industry. Meanwhile, the beverage also has the function of a nutritional supplement.
The soybean lecithin is a food surfactant approved by the world health organization, and has good wettability, permeability and nutrition. On the surface of the brown rice, the surface tension of water can be reduced, the water absorption softening of substances such as crude fibers, horny layers and the like in the pericarp, the seed coat and the aleurone layer of the brown rice is accelerated, and the water is accelerated to permeate into the endosperm of the brown rice, so that the endosperm starch of the brown rice can fully absorb water to meet the requirement of gelatinized water. In addition, the soybean lecithin has a nut delicate fragrance, and can improve the taste value of the brown rice. The addition of phospholipid also improves the nutritional value of the formula rice.
The staple grain brown rice nutritional rice provided by the invention comprises 0.1-4 parts by weight of vegetable oil; preferably, the vegetable oil is 0.5-3.5 parts by weight; more preferably, the vegetable oil comprises 0.8 to 3.0 parts by weight of vegetable oil; most preferably 1-2.5 parts by weight of vegetable oil.

The olive oil is rich in monounsaturated fatty acid and other active substances, has the effect of softening tough tissues such as crude fibers and stratum corneum cells in brown rice pericarp, seed coat and aleurone layer under heating, and various aromatic substances contained in the olive oil are fully volatilized and blended into rice or porridge in the cooking process, so that the taste is improved, and the bad smell can be lightened. The addition of olive oil also improves the nutritional value of the formula rice.
The olive oil is prepared by directly cold pressing fresh olive fruits, does not undergo heating and chemical treatment, and retains natural nutritional ingredients; the olive oil is rich in oleic acid which is a monounsaturated fatty acid, and also contains vitamin A, vitamin B, vitamin D, vitamin E, vitamin K, antioxidant and the like. Olive oil is considered as the oil most suitable for human nutrition among the oils and fats found so far. The monounsaturated fatty acid can not only supply heat energy to human body, but also adjust the proportion of high-density lipoprotein cholesterol and low-density lipoprotein cholesterol in human plasma, increase the level of high-density lipoprotein HDL which is beneficial to human health and reduce the level of low-density lipoprotein LDL which is not beneficial to human health, thereby preventing the excessive cholesterol in human body. Therefore, for people who are used to eat meat food and have excessive intake of saturated fatty acid and cholesterol, the olive oil is selected as the edible oil, so that the function of reducing blood fat can be effectively exerted, the functions of preventing hyperlipidemia and fatty liver and protecting heart can be assisted, and the occurrence of diseases such as hypertension, cardiovascular and cerebrovascular diseases and the like can be reduced.
