Description
Technical Field
The invention relates to the technical field of rice processing, in particular to a processing method of health-care rice with bamboo flavor.
Background
As is known, the main and minor cereals in China have certain defects in nutrient components, cannot completely meet the needs of human bodies, and particularly, most of proteins are insufficient or lack of certain essential amino acid. While the bamboo contains eighteen trace elements such as abundant dwarf sugar, vitamins, flavonoid carotene, selenium, phosphorus, silicon, potassium, iron, magnesium, boron and the like, and the nutrient substances are rich and complete. Wherein, the substances such as the short saccharides are natural good medicines for preventing and treating various diseases such as cancer, hypertension, constipation and the like, and also have the effects of beautifying and the like. In addition to this health care effect, the natural bamboo fragrance is also enjoyed by most people. Therefore, the bamboo fragrant rice is produced at the same time. The bamboo-fragrant rice is the organic combination of rice and bamboo, is light green rice, has strong bamboo fragrance, and can be used for cooking porridge and steaming rice at ordinary times. However, the quality of the bamboo fragrant rice sold in the market is not uniform.
Publication No. CN1265841A discloses a method for preparing health rice, which comprises soaking fresh bamboo leaves, bamboo shavings, bamboo juice, fresh loquat leaves, eucommia ulmoides, and palm leaves in edible alcohol, collecting the effective component extract by reduced pressure distillation, spraying the extract onto the surface of rice by a spray gun under stirring, and heating and drying to obtain emerald green health rice. The method directly uses alcohol to leach effective components such as fresh bamboo leaves and bamboo shavings, and has the defects of low leaching efficiency, low content of effective components in the obtained extract, and the like; the extracting solution is sprayed on the surface of the rice by a spray gun, so that the problems of loss of effective components and the like exist in the subsequent cleaning process of the rice. Based on the statement, the invention provides a processing method of health-care rice with bamboo flavor.
Disclosure of Invention
The invention aims to solve the problems of poor quality, low content of effective health-care ingredients, easy loss and the like of bamboo-flavored health-care rice in the prior art, and provides a processing method of bamboo-flavored health-care rice.
A processing method of health rice with bamboo flavor comprises the following steps:
s1, cleaning and drying fresh and tender fragrant and glutinous bamboo, crushing the dried fragrant and glutinous bamboo to obtain fragrant and glutinous bamboo dry powder, adding water into the fragrant and glutinous bamboo dry powder, uniformly mixing, and pulping to obtain fragrant and glutinous bamboo pulp;
s2, adding a leaching agent into the fragrant and glutinous bamboo serous fluid according to the mass ratio of 1:30-50, stirring and mixing uniformly at room temperature, extracting effective components in the fragrant and glutinous bamboo serous fluid by adopting an ultrasonic extraction process, and filtering to obtain a fragrant and glutinous bamboo extracting solution;
s3, selecting broken rice in the rice processing process as a raw material, cleaning the broken rice, removing impurities, drying, mixing the dried broken rice with walnut kernels, and crushing to obtain rice flour;
s4, adding the fragrant and glutinous bamboo extract into the rice flour according to the mass ratio of 1:55-75, stirring and mixing uniformly at the temperature of 38-58 ℃, and then performing spray drying, granulation and polishing to obtain the bamboo-flavored health-care rice.
Preferably, the mass ratio of the dry powder of the fragrant waxy bamboo to the water in the step S1 is 1: 7-12.
Preferably, the leaching agent in the step S2 is prepared by compounding ethanol, sodium citrate and enzyme in a mass ratio of 5-8:1-2: 1-2.
Preferably, the concentration of ethanol is 45%.
Preferably, the enzyme is one of protease, amylase, pectinase, cellulase, xylanase or beta-glucanase.
Preferably, the ultrasonic extraction conditions in step S2 are as follows: under the conditions that the frequency is 80-100 kHz and the temperature is 25-35 ℃, ultrasonic extraction is carried out for 5-10 min, then the temperature is continuously raised to 40-50 ℃, and ultrasonic extraction is carried out for 5-10 min.
Preferably, the mass ratio of the broken rice to the walnut kernels in the step S3 is 7-10: 1.
The processing method of the bamboo-flavor health-care rice provided by the invention has the following beneficial effects:
1. the invention adopts the fragrant and glutinous bamboo extract to be organically combined with the rice and the walnut, the prepared rice has high protein content, is rich in vitamins, essential amino acids and trace elements required by human bodies, has rich nutrient substances and high health care value, can effectively enhance the immunity of the human bodies and improve the oxidation resistance and disease resistance of the human bodies, and in addition, the health care rice prepared by the invention has strong bamboo fragrance and can enhance the appetite.
2. According to the invention, ethanol, sodium citrate and enzyme are compounded to prepare the leaching solution, the effective components of the fragrant and glutinous bamboo are extracted by using the leaching solution after the fragrant and glutinous bamboo is pulped, and the extraction rate of the effective components of the fragrant and glutinous bamboo is up to 98.7%.
3. The method selects broken rice in the rice processing process as a raw material, mixes and crushes the broken rice and walnut kernels, mixes the crushed rice and the walnut kernels with the fragrant glutinous bamboo extract, dries and granulates, greatly improves the market utilization value of the broken rice, and the obtained health-care rice has the advantages of simple processing method, low processing cost, high health-care component content, high nutritional value and popularization.
